Syntax

public static class GameObjectExtensions

Methods

ApplyLayerCacheRecursively(GameObject, Dictionary<GameObject, Int32>)

Reapplies previously cached hierarchy layers

Declaration

public static void ApplyLayerCacheRecursively(this GameObject root, Dictionary<GameObject, int> cache)

Parameters

Type	Name	Description
GameObject	root	Start point of the traverse
Dictionary<GameObject, Int32>	cache	The previously set layer for each object

ApplyToHierarchy(GameObject, Action<GameObject>)

Apply the specified delegate to all objects in the hierarchy under a specified game object.

Declaration

public static void ApplyToHierarchy(this GameObject root, Action<GameObject> action)

Parameters

Type	Name	Description
GameObject	root	Root game object of the hierarchy.
Action<GameObject>	action	Delegate to apply.

DestroyGameObject(GameObject, Single)

Destroys GameObject appropriately depending if in edit or playmode

Declaration

public static void DestroyGameObject(GameObject gameObject, float t = 0F)

Parameters

Type	Name	Description
GameObject	gameObject	GameObject to destroy
Single	t	time in seconds at which to destroy GameObject if applicable

ExportOBJAsync(GameObject, String, Boolean)

Export mesh data of current GameObject, and children if enabled, to file provided in OBJ format

Declaration

public static Task ExportOBJAsync(this GameObject root, string filePath, bool includeChildren = true)

Parameters

Type	Name	Description
GameObject	root
String	filePath
Boolean	includeChildren

Returns

Type	Description
Task

FindAncestorComponent<T>(GameObject, Boolean)

Find the first component of type T in the ancestors of the specified game object.

Declaration

public static T FindAncestorComponent<T>(this GameObject gameObject, bool includeSelf = true)
    where T : Component

Parameters

Type	Name	Description
GameObject	gameObject	Game object for which ancestors must be considered.
Boolean	includeSelf	Indicates whether the specified game object should be included.

Returns

Type	Description
T	The component of type T. Null if it none was found.

Type Parameters

Name	Description
T	Type of component to find.

ForEachComponent<T>(GameObject, Action<T>)

Perform an action on every component of type T that is on this GameObject

Declaration

public static void ForEachComponent<T>(this GameObject gameObject, Action<T> action)
    where T : Component

Parameters

Type	Name	Description
GameObject	gameObject	this gameObject
Action<T>	action	Action to perform.

Type Parameters

Name	Description
T	Component Type

IsComponentRequired<T>(GameObject, out List<Type>)

Checks if any MonoBehaviour on the given GameObject is using the RequireComponentAttribute requiring type T

Declaration

public static bool IsComponentRequired<T>(this GameObject gameObject, out List<Type> requiringTypes)
    where T : Component

Parameters

Type	Name	Description
GameObject	gameObject	the GameObject requiring the component
List<Type>	requiringTypes	A list of types that do require the component in question

Returns

Type	Description
Boolean	true if T appears in any RequireComponentAttribute, otherwise false

Type Parameters

Name	Description
T	The potentially required component

Remarks

Only functions when called within a UNITY_EDITOR context. Outside of UNITY_EDITOR, always returns false

IsInLayerMask(GameObject, LayerMask)

Determines whether or not a game object's layer is included in the specified layer mask.

Declaration

public static bool IsInLayerMask(this GameObject gameObject, LayerMask layerMask)

Parameters

Type	Name	Description
GameObject	gameObject	The game object whose layer to test.
LayerMask	layerMask	The layer mask to test against.

Returns

Type	Description
Boolean	True if gameObject's layer is included in layerMask, false otherwise.

SetChildrenActive(GameObject, Boolean)

Set all GameObject children active or inactive based on argument

Declaration

public static void SetChildrenActive(this GameObject root, bool isActive)

Parameters

Type	Name	Description
GameObject	root	GameObject parent to traverse from
Boolean	isActive	Indicates whether children GameObjects should be active or not

Remarks

Does not call SetActive on the top level GameObject, only its children

SetLayerRecursively(GameObject, Int32)

Set the layer to the given object and the full hierarchy below it.

Declaration

public static void SetLayerRecursively(this GameObject root, int layer)

Parameters

Type	Name	Description
GameObject	root	Start point of the traverse
Int32	layer	The layer to apply

SetLayerRecursively(GameObject, Int32, out Dictionary<GameObject, Int32>)

Set the layer to the given object and the full hierarchy below it and cache the previous layers in the out parameter.

Declaration

public static void SetLayerRecursively(this GameObject root, int layer, out Dictionary<GameObject, int> cache)

Parameters

Type	Name	Description
GameObject	root	Start point of the traverse
Int32	layer	The layer to apply
Dictionary<GameObject, Int32>	cache	The previously set layer for each object
