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.


Instance.AncestryChanged

child

parent

Instance.AttributeChanged

attribute

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


Instance.ChildAdded

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


Instance.ChildRemoved

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


Instance.DescendantAdded

descendant

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


Instance.DescendantRemoving

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.


Instance.Destroying

Instance.childAdded

Instance:AddTag

This example creates a Part and adds a few sparkle objects to the part. Then
it calls Part:ClearAllChildren() to remove all of the children.


Instance:ClearAllChildren

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

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.


Instance:Destroy

Instance:FindFirstAncestor

Instance:FindFirstAncestorOfClass

Instance:FindFirstAncestorWhichIsA

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

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

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.


Instance:GetDescendants

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.


Instance:GetFullName

Instance:GetStyled

Instance:GetTags

Instance:HasTag

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.

The following code demonstrates how a part can be re-added to the DataModel
after being removed:


Instance:Remove

Workspace.

This sample demonstrates the subtleties of the Changed event on normal objects
and "-Value" objects.


This code sample demonstrates the Changed event firing within a parent object.


Object.Changed

property

This code sample demonstrates how to save a value before a changed event fires
on it in order to get more information about a change.


This code sample demonstrates the equivalence of the `Changed` event and event
returned by `GetPropertyChangedSignal`.


Object:GetPropertyChangedSignal

Demonstrates determining the class of Workspace using `Class.Instance:IsA()`

Workspace is of class 'Workspace', so the first statement is true.
Workspace is not of class 'BasePart', so the second statement is false.
Workspace inherits from Instance and therefore is of class 'Instance', so the third statement is true.


Object:IsA

Object:isA

Object

Object.ClassName

/reference/engine/classes/UniversalConstraint.yaml

Ensures two axes on two bodies remain perpendicular.


An `Class.Actor` is a container for code that can be safely split into its own thread.

This method is asynchronous and returns an `Operation`, which represents the current state of the operation. It contains an endpoint path that you can poll to obtain the real response and applicable metadata. See the [documentation]({longRunningOperationsLink}) on long-running operations for more information.
            
The following sections describe the response and metadata objects that are provided when an operation completes.
