Syntax

public static class TransformExtensions

Methods

EnumerateAncestors(Transform, Boolean)

Enumerates the ancestors of the specified transform.

Declaration

public static IEnumerable<Transform> EnumerateAncestors(this Transform startTransform, bool includeSelf)

Parameters

Type	Name	Description
Transform	startTransform	Transform for which ancestors must be returned.
Boolean	includeSelf	Indicates whether the specified transform should be included.

Returns

Type	Description
IEnumerable<Transform>	An enumeration of all ancestor transforms of the specified start transform.

EnumerateHierarchy(Transform)

Enumerates all children in the hierarchy starting at the root object.

Declaration

public static IEnumerable<Transform> EnumerateHierarchy(this Transform root)

Parameters

Type	Name	Description
Transform	root	Start point of the traversion set

Returns

Type	Description
IEnumerable<Transform>

EnumerateHierarchy(Transform, ICollection<Transform>)

Enumerates all children in the hierarchy starting at the root object except for the branches in ignore.

Declaration

public static IEnumerable<Transform> EnumerateHierarchy(this Transform root, ICollection<Transform> ignore)

Parameters

Type	Name	Description
Transform	root	Start point of the traversion set
ICollection<Transform>	ignore	Transforms and all its children to be ignored

Returns

Type	Description
IEnumerable<Transform>

FindAncestorComponent<T>(Transform, Boolean)

Find the first component of type T in the ancestors of the specified transform.

Declaration

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

Parameters

Type	Name	Description
Transform	startTransform	Transform for which ancestors must be considered.
Boolean	includeSelf	Indicates whether the specified transform 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.

GetChildRecursive(Transform, String)

Walk hierarchy looking for named transform

Declaration

public static Transform GetChildRecursive(Transform t, string name)

Parameters

Type	Name	Description
Transform	t	root transform to start searching from
String	name	name to look for

Returns

Type	Description
Transform	returns found transform or null if none found

GetColliderBounds(Transform)

Calculates the bounds of all the colliders attached to this GameObject and all it's children

Declaration

public static Bounds GetColliderBounds(this Transform transform)

Parameters

Type	Name	Description
Transform	transform	Transform of root GameObject the colliders are attached to

Returns

Type	Description
Bounds	The total bounds of all colliders attached to this GameObject. If no colliders attached, returns a bounds of center and extents 0

GetDepth(Transform)

Gets the hierarchical depth of the Transform from its root. Returns -1 if the transform is the root.

Declaration

public static int GetDepth(this Transform t)

Parameters

Type	Name	Description
Transform	t	The transform to get the depth for.

Returns

Type	Description
Int32

GetFullPath(Transform, String, String)

An extension method that will get you the full path to an object.

Declaration

public static string GetFullPath(this Transform transform, string delimiter = ".", string prefix = "/")

Parameters

Type	Name	Description
Transform	transform	The transform you wish a full path to.
String	delimiter	The delimiter with which each object is delimited in the string.
String	prefix	Prefix with which the full path to the object should start.

Returns

Type	Description
String	A delimited string that is the full path to the game object in the hierarchy.

InverseTransformSize(Transform, Vector3)

Transforms the size from world to local.

Declaration

public static Vector3 InverseTransformSize(this Transform transform, Vector3 worldSize)

Parameters

Type	Name	Description
Transform	transform	The transform.
Vector3	worldSize	The world size

Returns

Type	Description
Vector3	World size.

IsParentOrChildOf(Transform, Transform)

Checks if the provided transforms are child/parent related.

Declaration

public static bool IsParentOrChildOf(this Transform transform1, Transform transform2)

Parameters

Type	Name	Description
Transform	transform1
Transform	transform2

Returns

Type	Description
Boolean	True if either transform is the parent of the other or if they are the same

TransformSize(Transform, Vector3)

Transforms the size from local to world.

Declaration

public static Vector3 TransformSize(this Transform transform, Vector3 localSize)

Parameters

Type	Name	Description
Transform	transform	The transform.
Vector3	localSize	The local size.

Returns

Type	Description
Vector3	World size.

TryGetDepth(Transform, Transform, ref Int32)

Tries to get the hierarchical depth of the Transform from the specified parent. This method is recursive.

Declaration

public static bool TryGetDepth(Transform target, Transform parent, ref int depth)

Parameters

Type	Name	Description
Transform	target	The transform to get the depth for
Transform	parent	The starting transform to look for the target transform in
Int32	depth	The depth of the target transform

Returns

Type	Description
Boolean	'true' if the depth could be retrieved, or 'false' because the transform is a root transform.
