ObjectValue

Inherits from: ValueBase → Instance → Object

Stores a single reference to another object. If this object is duplicated within Studio and the value refers to an object also being copied, then the new ObjectValue points to the copied object instead of the original. Otherwise, the same value is kept. Copying and pasting this object clears the value field.

Like all ValueBase objects, this single value is stored in the Value property. The Changed event fires with the new value being stored in the object, instead of a string representing the property being changed.

If streaming is enabled, the Value property is nil until the referenced object streams in, at which point the Changed event fires.

Events

Name	Type / Returns	Description
ObjectValue.Changed		Fires whenever the `ObjectValue.Value` is changed.
ObjectValue.changed

Inherited from Instance

Name	Type / Returns	Description
Instance.AncestryChanged		Fires when the `Instance.Parent` property of this object or one of its ancestors is changed.
Instance.AttributeChanged		Fires whenever an attribute is changed on the `Instance`.
Instance.ChildAdded		Fires after an object is parented to this `Instance`.
Instance.childAdded
Instance.ChildRemoved		Fires after a child is removed from this `Instance`.
Instance.DescendantAdded		Fires after a descendant is added to the `Instance`.
Instance.DescendantRemoving		Fires immediately before a descendant of the `Instance` is removed.
Instance.Destroying		Fires immediately before (or is deferred until after) the instance is destroyed via `Instance:Destroy()`.
Instance.StyledPropertiesChanged		Fires whenever any style property is changed on the instance, including when a property is set to `nil`.

Inherited from Object

Name	Type / Returns	Description
Object.Changed		Fires immediately after a property of the object changes, with some limitations.

ObjectValue.Changed

Fires whenever the ObjectValue.Value changes. It runs with the new value being stored in the argument object, instead of a string representing the property being changed.

Listening for the Changed signal can be useful in games that use ObjectValues to track game state, such as an RPG targeting system.

Parameters

Name	Type	Default	Description
value	Instance		The new value after the change.

Field	Value
security	None
