Description

Position, rotation and scale of an object.

Every object in a Scene has a Transform. It's used to store and manipulate the position, rotation and scale of the object. Every Transform can have a parent, which allows you to apply position, rotation and scale hierarchically. This is the hierarchy seen in the Hierarchy pane. They also support enumerators so you can loop through children using:

using UnityEngine;

public class Example : MonoBehaviour { // Moves all transform children 10 units upwards! void Start() { foreach (Transform child in transform) { child.position += Vector3.up * 10.0f; } } }

See Also: The component reference, Physics class.

Properties

childCountThe number of children the parent Transform has.
eulerAnglesThe rotation as Euler angles in degrees.
forwardReturns a normalized vector representing the blue axis of the transform in world space.
hasChangedHas the transform changed since the last time the flag was set to 'false'?
hierarchyCapacityThe transform capacity of the transform's hierarchy data structure.
hierarchyCountThe number of transforms in the transform's hierarchy data structure.
localEulerAnglesThe rotation as Euler angles in degrees relative to the parent transform's rotation.
localPositionPosition of the transform relative to the parent transform.
localRotationThe rotation of the transform relative to the transform rotation of the parent.
localScaleThe scale of the transform relative to the GameObjects parent.
localToWorldMatrixMatrix that transforms a point from local space into world space (Read Only).
lossyScaleThe global scale of the object (Read Only).
parentThe parent of the transform.
positionThe world space position of the Transform.
rightThe red axis of the transform in world space.
rootReturns the topmost transform in the hierarchy.
rotationA Quaternion that stores the rotation of the Transform in world space.
upThe green axis of the transform in world space.
worldToLocalMatrixMatrix that transforms a point from world space into local space (Read Only).

Public Methods

DetachChildrenUnparents all children.
FindFinds a child by name n and returns it.
GetChildReturns a transform child by index.
GetLocalPositionAndRotationGets the position and rotation of the Transform component in local space (that is, relative to its parent transform).
GetPositionAndRotationGets the position and rotation of the Transform component in world space.
GetSiblingIndexGets the sibling index.
InverseTransformDirectionTransforms a direction from world space to local space. The opposite of Transform.TransformDirection.
InverseTransformDirectionsTransforms multiple directions from world space to local space overwriting each original position with the transformed version. The opposite of Transform.TransformDirections.
InverseTransformPointTransforms position from world space to local space.
InverseTransformPointsTransforms multiple positions from world space to local space overwriting each original position with the transformed version.
InverseTransformVectorTransforms a vector from world space to local space. The opposite of Transform.TransformVector.
InverseTransformVectorsTransforms multiple vectors from world space to local space overwriting each original position with the transformed version. The opposite of Transform.TransformVectors.
IsChildOfIs this transform a child of parent?
LookAtRotates the transform so the forward vector points at /target/'s current position.
RotateUse Transform.Rotate to rotate GameObjects in a variety of ways. The rotation is often provided as an Euler angle and not a Quaternion.
RotateAroundRotates the transform about axis passing through point in world coordinates by angle degrees.
SetAsFirstSiblingMove the transform to the start of the local transform list.
SetAsLastSiblingMove the transform to the end of the local transform list.
SetLocalPositionAndRotationSets the position and rotation of the Transform component in local space (i.e. relative to its parent transform).
SetParentSet the parent of the transform.
SetPositionAndRotationSets the world space position and rotation of the Transform component.
SetSiblingIndexSets the sibling index.
TransformDirectionTransforms direction from local space to world space.
TransformDirectionsTransforms multiple directions from local space to world space overwriting each original direction with the transformed version.
TransformPointTransforms position from local space to world space.
TransformPointsTransforms multiple points from local space to world space overwriting each original point with the transformed version.
TransformVectorTransforms vector from local space to world space.
TransformVectorsTransforms multiple vectors from local space to world space overwriting each original vector with the transformed version.
TranslateMoves the transform in the direction and distance of translation.

nameThe name of the object.

Public Methods

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagChecks the GameObject's tag against the defined tag.
GetComponentGets a reference to a component of type T on the same GameObject as the component specified.
GetComponentInChildrenGets a reference to a component of type T on the same GameObject as the component specified, or any child of the GameObject.
GetComponentInParentGets a reference to a component of type T on the same GameObject as the component specified, or any parent of the GameObject.
GetComponentsGets references to all components of type T on the same GameObject as the component specified.

SendMessageCalls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwardsCalls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
TryGetComponentGets the component of the specified type, if it exists.
GetInstanceIDGets the instance ID of the object.
ToStringReturns the name of the object.

Static Methods

DestroyRemoves a GameObject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.

InstantiateClones the object original and returns the clone.

Operators

boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.
