LocalizationService is the service responsible for handling automated
translation.

It is used as a storage for `Class.LocalizationTable` objects used by
automatic text replacement.

LocalizationService will only use its child LocalizationTables for automatic
text replacement unless `Class.GuiBase2d.RootLocalizationTable` is specified
on a GUI object or its ancestors.


Returns a list of `Class.LocalizationTable` objects used for localizing
core scripts.


LocalizationService:GetCorescriptLocalizations

This code sample gets the country/region code for a local player and prints
"Hello, friend from Canada!" if the player's client IP geolocation is Canada.


Returns a country/region code string according to player's client IP
geolocation. The supported country/region codes are as follows:

- `Class.PolicyService:GetPolicyInfoForPlayerAsync()`, returns policy
  information about a player which is based on geolocation, age group and
  platform


LocalizationService:GetCountryRegionForPlayerAsync

player

The player that you are getting country/region information for.


A string indicating the country/region code of a player.


Returns country/region code string according to player's client IP
geolocation.


Returns an `Array`, where each element of the returned `Array` is itself
an `Array` of entries in the same format as described in
`Class.LocalizationTable:GetEntries()`. The order of the elements in the
returned `Array` is the same order that the
`Class.LocalizationTable|LocalizationTables` will be searched through to
attempt automated localization for the provided `Class.Instance`. The
entry elements within a particular `Class.LocalizationTable` are returned
in an unspecified order.

This function returns entries regardless of whether the object is a
`Class.GuiBase2d` with `Class.GuiBase2d.AutoLocalize` enabled. An object
that is a `Class.GuiBase2d` will not actually be automatically localized
unless `Class.GuiBase2d.AutoLocalize` is enabled.

The ordering of the tables is as follows:

- First, it looks for the earliest `Class.GuiBase2d` ancestor of the
  object (including the provided object) that has a
  `Class.GuiBase2d.RootLocalizationTable`. Tables then append in the same
  order as described in `Class.GuiBase2d.RootLocalizationTable` by going
  up through the `Class.LocalizationTable` ancestors of that
  `Class.GuiBase2d.RootLocalizationTable`. If no such
  `Class.GuiBase2d.RootLocalizationTable` is found, no tables append in
  this step. If `instance` is `nil`, no tables append in this step.
- Next, tables from the `Class.LocalizationTable` hierarchy under
  `Class.LocalizationService` append. For each child
  `Class.LocalizationTable` of `Class.LocalizationService`, it appends
  tables going up from the lowest descendant `Class.LocalizationTable` of
  the tables parented to the service, all the way up to the children of
  the service. If there are no children of `Class.LocalizationService`
  that are `Class.LocalizationTable|LocalizationTables`, then no tables
  append in this step.
- Finally, the cloud `Class.LocalizationTable` appends to the array. If
  there is no cloud `Class.LocalizationTable`, or the cloud
  `Class.LocalizationTable` has not yet loaded, then no table appends in
  this step.

This function does not yield. It will not wait until the cloud
`Class.LocalizationTable` has loaded.


LocalizationService:GetTableEntries

instance

An array of arrays, where each array is in the same format as
described in `Class.LocalizationTable:GetEntries()`.


Gets all entries used for automated localization.


This code sample attempts to retrieve a `Translator` object for the locale
"fr" (French).

`Class.LocalizationService:GetTranslatorForLocaleAsync()` is wrapped in a
pcall because it may error. If it does not error and returns a Translator,
prints "Hello in French:" followed by the French translation of "Hello
World!". If the function errors, it prints "GetTranslatorForLocaleAsync
failed:" followed by the error message.


This function takes a locale code as an argument and yields until the
cloud `Class.LocalizationTable` for that locale has been loaded, if
available. It then returns a `Class.Translator` object which can be used
to perform translations for that locale if any are available. The entries
used for localization are the entries provided by the
`Class.LocalizationTable` hierarchy under `Class.LocalizationService` as
well as the cloud table (if available). This will be the same set of
entries returned by `Class.LocalizationService:GetTableEntries(nil)`.

This function can error and thus should be wrapped in a `pcall()`.

- `Class.LocalizationService:GetTranslatorForPlayer()` gets the translator
  corresponding to the locale of the provided player. This function is
  deprecated and should not be used in new work.
- `Class.LocalizationService:GetTranslatorForPlayerAsync()` yields until
  the cloud `Class.LocalizationTable` for the locale of the provided
  player has loaded and then gets the translator corresponding to the
  locale of the provided player.


LocalizationService:GetTranslatorForLocaleAsync

locale

A Roblox supported language or locale code.


The `Class.Translator` instance for the specified locale.


Yields until the cloud `Class.LocalizationTable` for the argument locale
has been loaded - if available. Returns a `Class.Translator` instance to
be used for translations for the provided locale.


This code sample attempts to retrieve a `Translator` object for the local
player. `Class.LocalizationService:GetTranslatorForPlayerAsync()` is wrapped
in a pcall because it may error. If it does not error and returns a
Translator, it translates and prints "Hello World!" in the player's language.
If the function errors, it prints "GetTranslatorForLocaleAsync failed:"
followed by the error message.

`Class.LocalizationService:GetTranslatorForPlayer()` can also be used if you'd
like to get the player's translator without yielding until the function
returns.


This function takes a player as an argument and returns a
`Class.Translator` instance which can be used to perform translations for
that locale if any are available. The entries used for localization are
the entries provided by the `Class.LocalizationTable` hierarchy under
`Class.LocalizationService` as well as the cloud
`Class.LocalizationTable`, if it is available and already loaded. This
will be the same set of entries returned by
`Class.LocalizationService:GetTableEntries(nil)`.

This function does not yield. It will not wait until the cloud
`Class.LocalizationTable` has loaded.

See also:

- `Class.LocalizationService:GetTranslatorForPlayerAsync()` has the same
  functionality as this function, except that it yields until the cloud
  `Class.LocalizationTable` has been loaded.
- `Class.LocalizationService:GetTranslatorForLocaleAsync()`, returns a
  Translator to be used for translations using the provided locale.


LocalizationService:GetTranslatorForPlayer

The `Class.Player` that you are getting the `Class.Translator` for.


Returns a `Class.Translator` to be used for translations using the locale
data loaded.


This function takes a player as an argument and yields until the cloud
`Class.LocalizationTable` for that player's locale has been loaded, if
available. It then returns a `Class.Translator` object which can be used
to perform translations for that locale if any are available. The entries
used for localization are the entries provided by the
`Class.LocalizationTable` hierarchy under `Class.LocalizationService` as
well as the cloud table (if available). This will be the same set of
entries returned by `Class.LocalizationService:GetTableEntries(nil)`.

This function can error and thus should be wrapped in a `pcall()`.

See also:

- `Class.LocalizationService:GetTranslatorForPlayer()`, same functionality
  as this function except that it does not yield and does not wait until
  the cloud `Class.LocalizationTable` for the player's locale has been
  loaded. This function is deprecated and should not be used in new work.
- `Class.LocalizationService:GetTranslatorForLocaleAsync()`, returns a
  Translator to be used for translations using the provided locale.


LocalizationService:GetTranslatorForPlayerAsync

Yields until the cloud `Class.LocalizationTable` for the player's locale
has been loaded - if available. Returns a `Class.Translator` instance to
be used for translations for the provided locale.


LocalizationService

This property shows the locale ID used for the localization of core and
internal features such as `Class.CoreGui`. Returns a string with the two
letter code (for example, `en-us`) for the locale.


LocalizationService.RobloxLocaleId

The locale ID used for localizing core and internal features.


This property shows the locale ID that the local player has set for their
operating system.

This will return a string with the two letter code (for example, "en-us")
for the locale.

See also `Class.Player.LocaleId`, the locale ID that a user has set for
their Roblox account which is used for localizing in-experience content.
This will be a different value when Roblox does not yet internally support
that player's locale.


LocalizationService.SystemLocaleId

The locale ID that the local player has set for their operating system.


`Instance` is the base class for all classes in the Roblox class hierarchy
which can be part of the `Class.DataModel` tree.

It is not possible to directly create root `Instance` objects, but the special
`Datatype.Instance.new()` constructor creates objects via code, taking the
name of the class as a parameter and returning the created object.


Demonstrates detecting changes to an instance's ancestry by connecting to the
`Class.Instance.AncestryChanged` event.

The ChangingPart's Parent is set to different values overtime. The parent of
the part is the part's ancestor, so the `Class.Instance.AncestryChanged` event
will fire whenever it changes.


Fires when this instance is reparented or when any of its ancestors is
reparented.

You can use this event to track the deletion of an instance in Studio,
such as manual deletion in the Explorer or through a plugin. If you need
to detect when an instance is destroyed using `Class.Instance:Destroy()`,
use the `Class.Instance.Destroying` event instead.


Instance.AncestryChanged

child

The instance whose `Class.Instance.Parent|Parent` property changed,
which can be this instance or a more distant ancestor, **not**
necessarily the instance the handler is connected to.


parent

The new parent of the `child` parameter.


Fires when the `Class.Instance.Parent` property of this object or one of
its ancestors is changed.


This event fires whenever any attribute is changed on the instance,
including when an attribute is set to `nil`. The name of the changed
attribute is passed to the connected function.

For example, the following code snippet connects the `attributeChanged()`
function to fire whenever one of the part's attributes changes:

```lua
local Workspace = game:GetService("Workspace")

local part = Workspace.Part

local function attributeChanged(attributeName)
	print(attributeName, "changed")
end

part.AttributeChanged:Connect(attributeChanged)
```

See also `Class.Instance:GetAttributeChangedSignal()` which returns an
event that fires when a specific given attribute changes.


Instance.AttributeChanged

attribute

The name of the attribute that has been changed.


Fires whenever an attribute is changed on the `Class.Instance`.


This snippet prints the names of objects as they are added to the Workspace:


Fires after an object is parented to this `Class.Instance`.

Note, when using this method on a client to detect objects created by the
server it is necessary to use `Class.Instance:WaitForChild()` when
indexing these object's descendants. This is because the object and its
descendants are not guaranteed to replicate from the server to the client
simultaneously. For example:

```
local Workspace = game:GetService("Workspace")

Workspace.ChildAdded:Connect(function(child)
	-- Use WaitForChild() since descendants may not have replicated yet
	local head = child:WaitForChild("Head")
end)
```

Note, this event only operates for immediate children of the
`Class.Instance`. For an event that captures all descendants, use
`Class.Instance.DescendantAdded`.

See also `Class.Instance.ChildRemoved`.


Instance.ChildAdded

The `Class.Instance` that has been added.


Fires after an object is parented to this `Class.Instance`.


Instance.childAdded

This snippet prints the names of objects as they are removed from the
Workspace:


Fires after a child is removed from this `Class.Instance`.

Removed refers to when an object's parent is changed from this
`Class.Instance` to something other than this `Class.Instance`. Note, this
event will also fire when a child is destroyed (using
`Class.Instance:Destroy()`) as the destroy function sets an object's
parent to `nil`.

This event only operates for immediate children of the `Class.Instance`.
For an event that captures all descendants, use
`Class.Instance.DescendantRemoving`.

See also `Class.Instance.ChildAdded`.


Instance.ChildRemoved

The `Class.Instance` that has been removed.


Fires after a child is removed from this `Class.Instance`.


This following example will print the name of any object that is added to the
Workspace:


This event fires after a descendant is added to the `Class.Instance`.

As it fires for every descendant, parenting an object to the
`Class.Instance` will fire the event for this object and all of its
descendants individually.

If you're only concerned with the **direct children** of the
`Class.Instance`, use `Class.Instance.ChildAdded` instead.

See also `Class.Instance.DescendantRemoving`.


Instance.DescendantAdded

descendant

Fires after a descendant is added to the `Class.Instance`.


The following example prints the name of any descendant as it is being removed
from the Workspace:


This event fires **immediately before** the parent `Class.Instance`
changes such that a **descendant** instance will no longer be a
descendant. `Class.Instance:Destroy()|Destroy()` changes an instance's
`Class.Instance.Parent|Parent` to `nil`, so calling that method on a
descendant of the parent will cause this event to fire.

Since this event fires **before** the descendant's removal, the parent of
the descendant will be unchanged at the time of this event firing. If the
descendant is also a **direct child** of the parent, this event will fire
before `Class.Instance.ChildRemoved`.

If a descendant has children, this event fires with the descendant first,
followed by its descendants.

#### Warning

This event fires with the descendant object that is being removed.
Attempting to set the `Class.Instance.Parent|Parent` of the descendant to
something else will fail. Below is an example that demonstrates this:

```
local Workspace = game:GetService("Workspace")

Workspace.DescendantRemoving:Connect(function(descendant)
	-- Do not manipulate the parent of the descendant in this function!
	-- This event fires BECAUSE the parent was manipulated, and the change hasn't happened yet
	-- Therefore, it is problematic to change the parent like this:
	descendant.Parent = game
end)

local part = Instance.new("Part")
part.Parent = Workspace
part.Parent = nil
```

See also `Class.Instance.DescendantAdded|DescendantAdded`.


Instance.DescendantRemoving

The `Class.Instance` that is being removed.


Fires immediately before a descendant of the `Class.Instance` is removed.


This sample demonstrates how, when using Immediate signal behavior, an
Instance being destroyed remains in place until the connected function yields.


This sample demonstrates how, when using Deferred signal behavior, an Instance
is destroyed before the signal fires.


The `Class.Instance` will never be deleted from memory while a connected
function is still using it. However, if the function yields at any point,
the `Class.Instance` and its descendants will be parented to `nil`.

If the `Class.Workspace.SignalBehavior` property is set to
`Enum.SignalBehavior.Immediate`, this event fires immediately before the
`Class.Instance` or one of its ancestors is destroyed with
`Class.Instance:Destroy()`.

If the `Class.Workspace.SignalBehavior` property is set to
`Enum.SignalBehavior.Deferred`, this event fires at the next resumption
point, which will be after the `Class.Instance` or one of its ancestors is
destroyed with `Class.Instance:Destroy()`.

With `Enum.SignalBehavior.Deferred|Deferred` behavior, connecting a script
to its own `Class.Instance.Destroying` event is problematic, as the script
will be destroyed before the callback can be called (meaning it will not
execute).

When deleting an `Class.Instance` in Studio, such as manually deleting
through the [Explorer](/studio/explorer) or through a plugin,
the `Class.Instance` isn't destroyed. Instead, the parent is set to `nil`
which you can track with `Class.Instance.AncestryChanged`.


Instance.Destroying

Fires immediately before (or is deferred until after) the instance is
destroyed via `Class.Instance:Destroy()`.


This event fires whenever any style property is changed on the instance,
including when a property is set to `nil`.

```lua
local Players = game:GetService("Players")

local player = Players.LocalPlayer
local playerGui = player.PlayerGui
local HUDContainer = playerGui:WaitForChild("HUDContainer")
local meterBar = HUDContainer.MeterBar

local function stylePropertyChanged()
	print("Styled properties changed")
end

meterBar:StyledPropertiesChanged():Connect(stylePropertyChanged)
```


Instance.StyledPropertiesChanged

Fires whenever any style property is changed on the instance, including
when a property is set to `nil`.


This method applies a tag to the instance, with no effect if the tag is
already applied. Successfully adding a tag will fire a signal created by
`Class.CollectionService:GetInstanceAddedSignal()` with the given tag.

#### Warnings

- An instance's tags that were added client-side will be dropped if the
  server later adds or removes a tag on that instance because the server
  replicates all tags together and overwrites previous tags.

- When tagging an instance, it is common that some resources are used to
  give the tag its functionality, for example event connections or tables.
  To prevent memory leaks, it's a good idea to clean these up (disconnect,
  set to `nil`, etc.) when no longer needed for a tag. Do this when
  calling `Class.Instance:RemoveTag()`, calling
  `Class.Instance:Destroy()`, or in a function connected to a signal
  returned by `Class.CollectionService:GetInstanceRemovedSignal()`.


Instance:AddTag

The children function returns an array of the object's children.


Instance:children

Returns an array of the object's children.


This method destroys all of an instance's children and descendants.

```
local part = Instance.new("Part")

-- Add some sparkles
for i = 1, 3 do
	local sparkles = Instance.new("Sparkles")
	sparkles.Parent = part

  local sc = Instance.new("Sparkles")
  sc.Parent = sparkles
end

print("Children:", #part:GetChildren())  --> Children: 3

part:ClearAllChildren()

print("Children:", #part:GetChildren())  --> Children: 0
```

If you do not wish to destroy **all** children and descendants, use either
`Class.Instance:GetChildren()` or `Class.Instance:GetDescendants()` to
loop through those children/descendants and select what to destroy. For
example, the following code sample will destroy all
`Class.BasePart|BaseParts` descending from a `Class.Model`:

```
local Workspace = game:GetService("Workspace")

local model = Workspace:FindFirstChild("TestModel")

for _, descendant in model:GetDescendants() do
	if descendant:IsA("BasePart") then
		descendant:Destroy()
	end
end
```


Instance:ClearAllChildren

This method destroys all of an instance's children.


Demonstrates cloning a model using `Class.Instance:Clone()`.


`Clone()` creates a copy of an instance and all of its descendants,
ignoring all instances that are not
`Class.Instance.Archivable|Archivable`. The copy of the root instance is
returned by this method and its `Class.Instance.Parent|Parent` is set to
`nil`. Note that if the instance itself has
`Class.Instance.Archivable|Archivable` set to `false`, this method will
return `nil`.

If a reference property such as `Class.ObjectValue.Value` is set in a
cloned instance, the value of the copy's property depends on the
original's value:

- If a reference property refers to an instance that was **also** cloned,
  the copy will refer to the copy.
- If a reference property refers to an instance that was **not** cloned,
  the same value is maintained in the copy.


Instance:Clone

Create a copy of an instance and all its descendants, ignoring instances
that are not `Class.Instance.Archivable|Archivable`.


Instance:clone

Demonstrates destroying a Part using the `Class.Instance:Destroy()` function.

This function is the correct way to dispose of objects that are no longer
required.


Sets the `Class.Instance.Parent` property to `nil`, locks the
`Class.Instance.Parent` property, disconnects all connections, and calls
`Destroy()` on all children. This method is the correct way to dispose of
objects that are no longer required.

Disposing of unneeded objects is important, since unnecessary objects and
connections in a place use up memory which can lead to serious performance
issues over time.

As a best practice after calling `Destroy()` on an object, set any
variables referencing the object (or its descendants) to `nil`. This
prevents your code from accessing anything to do with the object.

```lua
local part = Instance.new("Part")
part.Name = "Hello, world"
part:Destroy()
-- Don't do this:
print(part.Name)  --> "Hello, world"
-- Do this to prevent the above line from working:
part = nil
```

Once an `Class.Instance` has been destroyed by this method, it cannot be
reused because the `Class.Instance.Parent` property is locked. To
**temporarily** remove an object instead of destroying it, set
`Class.Instance.Parent|Parent` to `nil`. For example:

```
local Workspace = game:GetService("Workspace")

object.Parent = nil
task.wait(2)
object.Parent = Workspace
```

To destroy an object after a set amount of time, use
`Class.Debris:AddItem()`.


Instance:Destroy

Sets the `Class.Instance.Parent` property to `nil`, locks the
`Class.Instance.Parent` property, disconnects all connections, and calls
`Destroy()` on all children.


Instance:destroy

Returns the first ancestor of the `Class.Instance` whose
`Class.Instance.Name` is equal to the given name.

This method works upwards, meaning it starts at the instance's immediate
`Class.Instance.Parent` and works up towards the `Class.DataModel`. If no
matching ancestor is found, it returns `nil`.

The following code snippet would find the first ancestor of the object
named `Car`.

```
local car = object:FindFirstAncestor("Car")
```

For variants of this method that find ancestors of a specific class,
please see `Class.Instance:FindFirstAncestorOfClass()` and
`Class.Instance:FindFirstAncestorWhichIsA()`.


Instance:FindFirstAncestor

name

The `Class.Instance.Name` to be looked for.


Returns the first ancestor of the `Class.Instance` whose
`Class.Instance.Name` is equal to the given name.


Returns the first ancestor of the `Class.Instance` whose
`Class.Object.ClassName` is equal to the given className.

This method works upwards, meaning it starts at the instance's immediate
`Class.Instance.Parent` and works up towards the `Class.DataModel`. If no
matching ancestor is found, it returns `nil`.

A common use of this method is finding the `Class.Model` a
`Class.BasePart` belongs to. For example:

```
local model = part:FindFirstAncestorOfClass("Model")
```

This method is a variant of `Class.Instance:FindFirstAncestor()` which
checks the `Class.Object.ClassName` property rather than
`Class.Instance.Name`. `Class.Instance:FindFirstAncestorWhichIsA()` also
exists, using the `Class.Object:IsA()` method instead to respect class
inheritance.


Instance:FindFirstAncestorOfClass

className

The `Class.Object.ClassName` to be looked for.


Returns the first ancestor of the `Class.Instance` whose
`Class.Object.ClassName` is equal to the given className.


Returns the first ancestor of the `Class.Instance` for whom
`Class.Object:IsA()` returns true for the given className.

This method works upwards, meaning it starts at the instance's immediate
`Class.Instance.Parent` and works up towards the `Class.DataModel`. If no
matching ancestor is found, it returns `nil`.

Unlike `Class.Instance:FindFirstAncestorOfClass()`, this method uses
`Class.Object:IsA()` which respects class inheritance. For example:

```
print(part:IsA("Part"))  --> true
print(part:IsA("BasePart"))  --> true
print(part:IsA("Instance"))  --> true
```

Therefore, the following code sample will return the first
`Class.BasePart` ancestor, regardless of if it is a `Class.WedgePart`,
`Class.MeshPart` or `Class.Part`.

```
local part = object:FindFirstAncestorWhichIsA("BasePart")
```

See also `Class.Instance:FindFirstAncestor()`.


Instance:FindFirstAncestorWhichIsA

Returns the first ancestor of the `Class.Instance` for whom
`Class.Object:IsA()` returns true for the given className.


The below would look in Workspace for an object name "Brick". If found, it
will change the name of the object to "Foo".


Returns the first child of the `Class.Instance` with the given name, or
`nil` if no such child exists. If the optional `recursive` argument is
`true`, this method searches all descendants rather than only the
immediate children of the `Class.Instance`.

#### Checking the Existence of an Object

`FindFirstChild()` is necessary if you need to verify an object exists
before continuing. Attempting to index a child by name using the dot
operator throws an error if the child doesn't exist.

```lua
local Workspace = game:GetService("Workspace")

-- The following line errors if the part doesn't exist in the workspace
Workspace.Part.Transparency = 0.5
```

A better approach is to use `FindFirstChild()` to first check for `Part`,
then use an `if` statement to run code that needs it.

```lua
local Workspace = game:GetService("Workspace")

local part = Workspace:FindFirstChild("Part")
if part then
	part.Transparency = 0.5
end
```

#### Finding a Child Whose Name Matches a Property

Sometimes the `Class.Instance.Name|Name` of an object is the same as that
of a property of its `Class.Instance.Parent|Parent`. When using the dot
operator, properties take precedence over children if they share a name.

In the following example, a `Class.Folder` called `Color` is added to a
`Class.Part`, which also has the `Class.Part.Color` property. Notice that
`part.Color` refers to the `Datatype.Color3` property value, not the child
`Class.Folder` instance. A benefit of using
`Class.Instance:FindFirstChild()|FindFirstChild()` is that the
introduction of new properties does not impose a risk on your code.

```lua
local part = Instance.new("Part")
local folder = Instance.new("Folder")
folder.Name = "Color"
folder.Parent = part
local c1 = part.Color  -- The property
local c2 = part:FindFirstChild("Color")  -- The child folder
```

#### Performance Notes

`Class.Instance:FindFirstChild()|FindFirstChild()` takes about 20% longer
than using the dot operator and almost 8 times longer than simply storing
a reference to an object. Therefore, you should avoid calling it in
performance-dependent code such as in tight loops or functions connected
to `Class.RunService.Heartbeat` and `Class.RunService.PreRender`. Instead,
store the result in a variable, or consider using
`Class.Instance.ChildAdded|ChildAdded` or
`Class.Instance:WaitForChild()|WaitForChild()` to detect when a child of a
given name becomes available.


Instance:FindFirstChild

The `Class.Instance.Name` to be searched for.


recursive

Whether or not the search should be conducted recursively.


Returns the first child of the `Class.Instance` found with the given name.


Instance:findFirstChild

Returns the first child of the `Class.Instance` whose
`Class.Object.ClassName|ClassName` is equal to the given `className`.
Unlike `Class.Instance:FindFirstChildWhichIsA()`, this method only returns
objects whose class matches `className`, ignoring class inheritance. If no
matching child is found, this method returns `nil`.


Instance:FindFirstChildOfClass

Returns the first child of the `Class.Instance` whose
`Class.Object.ClassName|ClassName` is equal to the given class name.


Returns the first child of the `Class.Instance` for whom
`Class.Object:IsA()` returns true for the given className.

If no matching child is found, this method returns `nil`. If the optional
recursive argument is true, this method searches all descendants rather
than only the immediate children of the `Class.Instance`.

Unlike `Class.Instance:FindFirstChildOfClass()`, this method uses
`Class.Object:IsA()` which respects class inheritance. For example:

```lua
print(part:IsA("Part")) --> true
print(part:IsA("BasePart")) --> true
print(part:IsA("Instance")) --> true
```

Therefore, the following code sample will return the first
`Class.BasePart` child, regardless of if it is a `Class.WedgePart`,
`Class.MeshPart` or `Class.Part`.

```
local part = object:FindFirstChildWhichIsA("BasePart")
```

Developers looking for a child by name, should use
`Class.Instance:FindFirstChild()` instead.


Instance:FindFirstChildWhichIsA

The `Class.Object.ClassName` to be searched for.


Returns the first child of the `Class.Instance` for whom
`Class.Object:IsA()` returns true for the given className.


Returns the first descendant found with the given `Class.Instance.Name`.

This method is disabled and cannot be used. To find the first descendant
of an instance, consider using the `recursive` parameter on
`Class.Instance:FindFirstChild()` instead.


Instance:FindFirstDescendant

The `Class.Instance.Name` to search for.


Returns the first descendant found with the given `Class.Instance.Name`.


If the `Class.Instance` is an `Class.Actor`, the `Class.Actor` itself is
returned. Otherwise, its closest ancestor `Class.Actor` is returned. If no
ancestor is an `Class.Actor`, the result is `nil`.


Instance:GetActor

Returns the `Class.Actor` associated with the Instance, if any.


This method returns the value which has been assigned to the given
attribute name. If no attribute has been assigned, `nil` is returned.

For example, the following code snippet sets and then gets the value of
the instance's `InitialPosition` attribute:

```lua
local Workspace = game:GetService("Workspace")

local part = Workspace.Part
part:SetAttribute("InitialPosition", part.Position)

local initialPosition = instance:GetAttribute("InitialPosition")
print(initialPosition)
```

#### See Also

- `Class.Instance:SetAttribute()` which sets the attribute with the given
  name to the given value.
- `Class.Instance:GetAttributes()` which returns a dictionary of key‑value
  pairs for each of the instance's attributes.


Instance:GetAttribute

The name of the attribute being retrieved.


The value which has been assigned to the given attribute name. If no
attribute has been assigned, `nil` is returned.


Returns the value which has been assigned to the given attribute name.


This method returns an event that behaves exactly like the
`Class.Object.Changed|Changed` event, except that it only fires when the
specific given attribute changes; effectively it is similar to
`Class.Object:GetPropertyChangedSignal()|GetPropertyChangedSignal()` but
for attributes.

It's generally a good idea to use this method instead of a connection to
`Class.Object.Changed|Changed` with a function that checks the attribute
name. Subsequent calls to this method on the same object with the same
attribute name return the same event.

The following code example returns a signal that fires the function
`attributeChanged()` when the part's `InitialPosition` attribute changes:

```lua
local Workspace = game:GetService("Workspace")

local part = Workspace.Part
part:SetAttribute("InitialPosition", part.Position)

local function attributeChanged()
	print("Attribute changed")
end

part:GetAttributeChangedSignal("InitialPosition"):Connect(attributeChanged)
```

See also `Class.Instance.AttributeChanged` which fires whenever any
attribute is changed on the instance.


Instance:GetAttributeChangedSignal

The name of the specified attribute for which the change signal is
being returned.


An event that fires when the given attribute changes.


Returns an event that fires when the given attribute changes.


This method returns a dictionary of key‑value pairs for each attribute
where the key is the attribute's name and the value is a non‑`nil` value.

For example, the following code snippet outputs an instance's attributes
and values:

```lua
local Workspace = game:GetService("Workspace")

local part = Workspace.Part
part:SetAttribute("InitialPosition", part.Position)
part:SetAttribute("CanUse", true)

for name, value in part:GetAttributes() do
	print(name .. " = " .. value)
end
```

See also `Class.Instance:GetAttribute()` which returns the value that has
been assigned to the given attribute name.


Instance:GetAttributes

A dictionary of string → variant pairs for each attribute where the
string is the name of the attribute and the variant is a non-nil
value.


Returns a dictionary of the instance's attributes.


The below would print the name of all objects currently in Workspace when ran.


Returns an array (a numerically indexed table) containing all of the
instance's direct children, or every `Class.Instance` whose
`Class.Instance.Parent|Parent` is equal to the object. The array can be
iterated upon using either a numeric or generic `for` loop:

```lua
local Workspace = game:GetService("Workspace")

-- Numeric loop example
local children = Workspace:GetChildren()
for i = 1, #children do
	local child = children[i]
	print(child.Name .. " is child number " .. i)
end
```

```lua
local Workspace = game:GetService("Workspace")

-- Generic loop example
local children = Workspace:GetChildren()
for i, child in children do
	print(child.Name .. " is child number " .. i)
end
```

Note that the returned array is **not** sorted in any particular order, so
manual sorting (for example using `Library.table.sort()`) is advised for
sorting the children returned by this method.

See also the `Class.Instance:GetDescendants()|GetDescendants()` method.


Instance:GetChildren

An array containing the instance's children.


Returns an array containing all of the instance's children.


Instance:getChildren

Returns a coded string of the debug ID used internally by Roblox. Note
that:

- This item is protected. Attempting to use it in a `Class.Script` or
  `Class.LocalScript` will cause an error.
- A debug ID is an ID used in debugging processes. It allows a debugger to
  read each instruction before an application processes it. All objects in
  Roblox act like processes and each run instructions (or 'code') that can
  be debugged if needed.
- This can be helpful for plugins which need to distinguish similar
  objects from one-another (such as objects that share the same name).


Instance:GetDebugId

scopeLength

Returns a coded string of the debug ID used internally by Roblox.


GetDescendants is often used to do something to all the descendants that are a
particular type of object. The code in this example uses GetDescendants and
`Class.Instance:IsA()` to find all of the parts in the workspace and turns
them green.


This object method returns an array that contains all of the descendants
of that object. Unlike `Class.Instance:GetChildren()`, which only returns
the immediate children of an object, this method finds every child of the
object, every child of those children, and so on.

Note that the returned array is **not** sorted in any particular order, so
manual sorting (for example using `Library.table.sort()`) is advised for
sorting the descendants returned by this method. Also consdier the
`Class.Instance:QueryDescendants()|QueryDescendants()` method to query
descendants by a combination of selectors and combinators.


Instance:GetDescendants

An array containing the instance's descendants.


Returns an array containing all of the descendants of the instance.


This code sample demonstrates the behavior of `Class.Instance:GetFullName()`.
It shows how the function behaves when called on an object not in the
`DataModel` hierarchy, and it also shows how the return value does not escape
special characters.


This code sample re-implements the `Class.Instance:GetFullName()` function in
Lua.


Returns a string describing the instance's ancestry. The string is a
concatenation of the `Class.Instance.Name|Name` of the object and its
ancestors, separated by periods. The `Class.DataModel` (`game`) is not
considered. For example, a `Class.Part` in the `Class.Workspace` may
return `Class.Workspace.Part`.

When called on an `Class.Instance` that is not a descendant of the
`Class.DataModel`, this method considers all ancestors up to and including
the topmost one without a `Class.Instance.Parent|Parent`.

This method is useful for logging and debugging. You shouldn't attempt to
parse the returned string for any useful operation; this method does not
escape periods (or any other symbol) in object names. In other words,
although its output often appears to be a valid Luau identifier, it is not
guaranteed.


Instance:GetFullName

Returns a string describing the instance's ancestry.


This method returns the styled or explicitly modified value of the
specified property, or else the default property value if it hasn't been
styled/modified. This differs slightly from accessing the property value
directly, such as `[GuiObject].Rotation`, which returns the default or
modified value of the property.

```lua
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local player = Players.LocalPlayer
local playerGui = player.PlayerGui
local HUDContainer = playerGui:WaitForChild("HUDContainer")

local coreSheet = ReplicatedStorage:FindFirstChild("CoreSheet")
local rule = coreSheet:FindFirstChildWhichIsA("StyleRule")
rule.Selector = "TextButton"

-- Reference to a button
local button = HUDContainer:FindFirstChildWhichIsA("TextButton")

print(button:GetStyled("Rotation")) --> 0 (default value)
print(button.Rotation) --> 0 (default value)

-- Apply rotation through style rule property
rule:SetProperty("Rotation", 30)

print(button:GetStyled("Rotation")) --> 30 (styled value based on rule)
print(button.Rotation) --> 0 (default value)

-- Explicitly modify/override styled property
button.Rotation = 45

print(button:GetStyled("Rotation")) --> 45 (modified value)
print(button.Rotation) --> 45 (modified value)
```


Instance:GetStyled

selector

Optional selector for the pseudo instance you are targeting on the
instance.


The styled or explicitly modified value of the specified property, or
else the default property value if it hasn't been styled/modified.


Returns the styled or explicitly modified value of the specified property,
or else the default property value if it hasn't been styled/modified.


This method returns an event that behaves exactly like the
`Class.Instance.StyledPropertiesChanged|StyledPropertiesChanged` event,
except that it only fires when the given style property changes. It's
generally a good idea to use this method instead of a connection to
`Class.Instance.StyledPropertiesChanged|StyledPropertiesChanged` with a
function that checks the property name. Subsequent calls to this method on
the same object with the same property name return the same event.

Note that this event will not pass any arguments to a connected function,
so the value of the changed property must be read directly within a
script.

```lua
local Players = game:GetService("Players")

local player = Players.LocalPlayer
local playerGui = player.PlayerGui
local HUDContainer = playerGui:WaitForChild("HUDContainer")
local meterBar = HUDContainer.MeterBar

local function stylePropertyChanged()
	print("Style property changed!")
end

meterBar:GetStyledPropertyChangedSignal("AnchorPoint"):Connect(stylePropertyChanged)
```


Instance:GetStyledPropertyChangedSignal

property

Name of the style property for which to listen for changes.


Event that fires when the given style property changes.


This method returns an array of the tags applied to the given instance, as
strings. You can add tags either in Studio in the
[Properties](/studio/properties) window or at runtime with
`Class.Instance:AddTag()|AddTag()`.

This method is useful when you want to do something with multiple tags on
an instance at once. However, it is inefficient to use this method to
check for the existence of a single tag; instead, use
`Class.Instance:HasTag()|HasTag()` to check for a specific tag.


Instance:GetTags

Gets an array of all tags applied to the instance.


This method returns `true` if the provided tag has been added to the
object. You can add tags either in Studio in the
[Properties](/studio/properties) window or at runtime with
`Class.Instance:AddTag()|AddTag()`.


Instance:HasTag

Check whether the instance has a given tag.


Demonstrates determining if one instance is the ancestor of another using
`Class.Instance:IsAncestorOf()`

Workspace and SpawnLocation are ancestors of the SpawnLocation's decal.
Workspace is an ancestor of SpawnLocation.

SpawnLocation and its decal are descendants of Workspace, not ancenstors.
Decal is a descendant to SpawnLocation, not an ancestor.


Returns true if an `Class.Instance` is an ancestor of the given
descendant.

An `Class.Instance` is considered the ancestor of an object if the
object's `Class.Instance.Parent` or one of it's parent's
`Class.Instance.Parent` is set to the `Class.Instance`.

See also, `Class.Instance:IsDescendantOf()`.


Instance:IsAncestorOf

True if the `Class.Instance` is an ancestor of the given descendant.


Returns true if an `Class.Instance` is an ancestor of the given
descendant.


Returns `true` if an `Class.Instance` is a descendant of the given
ancestor.

Note that `IsDescendantOf()` cannot be used with a parameter of `nil` to
check if an object has been removed.

See also `Class.Instance:IsAncestorOf()`.


Instance:IsDescendantOf

ancestor

True if the `Class.Instance` is a descendant of the given ancestor.


Returns `true` if an `Class.Instance` is a descendant of the given
ancestor.


Instance:isDescendantOf

This method indicates whether a specific property has been modified from
the code‑instantiated default. If called on an instance newly created via
code (`Datatype.Instance.new()`), this method will return `false`. If
called on an object newly created by Studio workflows such as
[Explorer](/studio/explorer) window insertion, the result may
differ.

For example, querying the
`Class.TextLabel.BackgroundColor3|BackgroundColor3` property of a
`Class.TextLabel` inserted via the [Explorer](/studio/explorer)
will return `true`, but querying the same property of a `Class.TextLabel`
created through `Datatype.Instance.new()` will return `false`, assuming no
other changes were made to its
`Class.TextLabel.BackgroundColor3|BackgroundColor3`.

Note that this method only returns useful results for services and
user‑creatable instances. Return values for system‑populated properties of
instances like `Class.PackageLink` is undefined behavior.

Also note that if this method returns `true`, styling will **not** affect
the property because explicitly modifying a property takes precedence over
styling it. To reset a property to its code‑instantiated default and allow
styling on it, use
`Class.Instance:ResetPropertyToDefault()|ResetPropertyToDefault()`.


Instance:IsPropertyModified

Boolean indicating whether the property is modified from its
code‑instantiated default.


Returns `true` if the value stored in the specified property is not equal
to the code-instantiated default.


This object method returns an array that contains all descendants of the
object that match the provided `selector` string. `selector` can include
multiple selectors and combinators to match characteristics such as the
class name, instance name, and hierarchy relationships, as well as
specific values of instance properties and attributes. The `selector`
grammar is similar to the one used in `Class.StyleRule`, with only a few
differences regarding which parts of the grammar are supported or not.

#### Selectors

- `ClassName` — Matches instances of the specified class in a
  `Class.Object:IsA()` relationship.
- `.Tag` — Matches instances tagged with a `Class.CollectionService` tag.
- `#Name` — Matches instances of a specific `Class.Instance.Name`.
- `[property = value]` — Matches instances which have the specified
  property and that property has the specified value. Boolean, number, and
  string values are supported. Letters, numbers, `_`, and `-` can be used
  without putting the value in quotation marks.
- `[$attribute]` — Matches instances which have the specified
  [attribute](/studio/properties#instance-attributes) set.
- `[$attribute = value]` — Matches instances which have the specified
  attribute **and** that attribute has the specified value. Same
  limitations apply as for property selectors. If you want to check for
  the absence of an attribute, do not query it as `nil`; instead use the
  `:not` pseudo‑class as in `:not([$attribute])`.

Selectors can also be combined. For example,
`Model.Apple[$Variety = Fuji][$Flavor = 4]` will match instances which are
a `Class.Model` tagged as `Apple` and which have a `Variety` attribute
equal to `Fuji` as well as a `Flavor` attribute equal to `4`.

```lua
local Workspace = game:GetService("Workspace")

-- Get all MeshPart descendants
print(Workspace:QueryDescendants("MeshPart"))

-- Get all descendants tagged as "Fruit"
print(Workspace:QueryDescendants(".Fruit"))

-- Get all descendants with the name "RedTree"
print(Workspace:QueryDescendants("#RedTree"))

-- Get all descendants with CanCollide property set to false
print(Workspace:QueryDescendants("[CanCollide = false]"))

-- Get all descendants with a "FuelCapacity" attribute assigned
print(Workspace:QueryDescendants("[$FuelCapacity]"))
-- Get all descendants with a "FuelCapacity" attribute set to 75
print(Workspace:QueryDescendants("[$FuelCapacity = 75]"))
```

#### Combinators

Combinators let you mix basic selectors to match deeper hierarchy
relationships.

- `>` — Matches instances that are **direct children** of the previous
  filter matches.

- `>>` — Matches instances that are **descendants** of the previous filter
  matches. This is the default first filter, meaning that `SpotLight.Red`
  is the same as `>> SpotLight.Red`.

- `,` — Specifies a list of multiple independent selectors for the
  descendant query. Only elements matching the filter are placed in the
  returned array; `nil` will not be included for non‑matches in a query
  list.

```lua
local Workspace = game:GetService("Workspace")

-- Get direct children of any Model that are tagged as "SwordPart"
print(Workspace:QueryDescendants("Model > .SwordPart"))

-- Get direct children which are a Part and are tagged as "Apple"
print(Workspace:QueryDescendants("> Part.Apple"))

-- Get descendants of any Model with an attribute "OnFire" set to true
print(Workspace:QueryDescendants("Model >> [$OnFire = true]"))

-- Get MeshPart descendants tagged as "SwordPart" OR with an attribute "OnFire" set to true
print(Workspace:QueryDescendants("MeshPart.SwordPart, MeshPart[$OnFire = true]"))
```

#### Pseudo-class selectors

- `:not(complex-selector-list)` — Allows selecting instances which do
  **not** match any of the selectors inside, effectively performing a
  negation of the selectors. Since the expression inside is a list of
  complex selectors, it's possible to filter based on multiple conditions.

- `:has(relative-selector-list)` — Allows selecting instances based on
  which instances they contain inside. The selector list is evaluated
  relative to each instance.

```lua
local Workspace = game:GetService("Workspace")

-- Get all descendants which are NOT of class SpotLight
print(Workspace:QueryDescendants(":not(SpotLight)"))
-- Get all descendants which are NOT of class SpotLight OR PointLight
print(Workspace:QueryDescendants(":not(SpotLight, PointLight)"))
-- Get all descendants which do NOT have an attribute "OnFire"
print(Workspace:QueryDescendants(":not([$OnFire])"))
-- Get all descendants EXCEPT children of a Model tagged as "SwordPart"
print(Workspace:QueryDescendants(":not(Model > .SwordPart)"))

-- Get descendants which contain a Tool instance as their own descendant
print(Workspace:QueryDescendants(":has(Tool)"))
-- Get MeshPart descendants which contain a direct child tagged as "SwordPart"
print(Workspace:QueryDescendants("MeshPart:has(> .SwordPart)"))

-- Get MeshPart descendants with direct children NOT of SurfaceAppearance or Texture class
print(Workspace:QueryDescendants("MeshPart:has(> :not(SurfaceAppearance, Texture))"))
```


Instance:QueryDescendants

Returns an array containing all descendants of the instance that match the
`selector` string.


Instance

`Instance` is the base class for all classes in the Roblox class hierarchy
which can be part of the `Class.DataModel` tree.
