Inherits from Component,IEnumerable
Position, rotation and scale of an object.
物體的位置、旋轉和縮放。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:
場景中的每一個物體都有一個Transform。用于儲存并操控物體的位置、旋轉和縮放。每一個Transform可以有一個父級，允許你分層次應用位置、旋轉和縮放。可以在Hierarchy面板查看層次關系。他們也支持計數器（enumerator），因此你可以使用循環遍歷子物體。
C#
javaScript
using UnityEngine;using System.Collections;public class example : MonoBehaviour {public void Awake() {foreach (Transform child in transform) {child.position += Vector3.up * 10.0F;}}}
// Moves all transform children 10 units upwards!//向上移動所有變換的子物體10個單位for (var child : Transform in transform) {child.position += Vector3.up * 10.0;}

Variables變量
positionThe position of the transform in world space. 在世界空間坐標transform的位置。
localPositionPosition of the transform relative to the parent transform. 相對于父級的變換的位置。
eulerAnglesThe rotation as Euler angles in degrees. 旋轉作為歐拉角度。
localEulerAnglesThe rotation as Euler angles in degrees relative to the parent transform's rotation. 旋轉作為歐拉角度，相對于父級的變換旋轉角度。
rightThe red axis of the transform in world space. 在世界空間坐標變換的紅色軸。也就是x軸。
upThe green axis of the transform in world space. 在世界空間坐標變換的綠色軸。也就是y軸。
forwardThe blue axis of the transform in world space. 在世界空間坐標變換的藍色軸。也就是z軸。
rotationThe rotation of the transform in world space stored as a Quaternion. 在世界空間坐標物體變換的旋轉角度作為Quaternion儲存。
localRotationThe rotation of the transform relative to the parent transform's rotation. 物體變換的旋轉角度相對于父級的物體變換的旋轉角度。
localScaleThe scale of the transform relative to the parent. 相對于父級物體變換的縮放。
parentThe parent of the transform. 物體變換的父級。
worldToLocalMatrixMatrix that transforms a point from world space into local space (Read Only). 矩陣變換的點從世界坐標轉為自身坐標（只讀）。
localToWorldMatrixMatrix that transforms a point from local space into world space (Read Only). 矩陣變換的點從自身坐標轉為世界坐標（只讀）。
rootReturns the topmost transform in the hierarchy. 返回層次最高的變換。
childCountThe number of children the Transform has. 變換的子物體數量。
lossyScaleThe global scale of the object (Read Only). 物體的全局縮放（只讀）。
Functions函數
TranslateMoves the transform in the direction and distance of translation. 移動transform在translation的方向和距離。
RotateApplies a rotation of eulerAngles.z degrees around the z axis, eulerAngles.x degrees around the x axis, and eulerAngles.y degrees around the y axis (in that order). 應用一個歐拉角的旋轉角度，eulerAngles.z度圍繞z軸，eulerAngles.x度圍繞x軸，eulerAngles.y度圍繞y軸（這樣的順序）。
RotateAroundRotates the transform about axis passing through point in world coordinates by angle degrees. 按照angle度通過在世界坐標的point軸旋轉物體。
LookAtRotates the transform so the forward vector points at /target/'s current position. 旋轉物體，這樣向前向量指向target的當前位置。
TransformDirectionTransforms direction from local space to world space. 從自身坐標到世界坐標變換方向。
InverseTransformDirectionTransforms a direction from world space to local space. The opposite of Transform.TransformDirection. 變換方向從世界坐標到自身坐標。和Transform.TransformDirection相反。
TransformPointTransforms position from local space to world space. 變換位置從自身坐標到世界坐標。
InverseTransformPointTransforms position from world space to local space. The opposite of Transform.TransformPoint. 變換位置從世界坐標到自身坐標。和Transform.TransformPoint相反。
DetachChildrenUnparents all children. 所有子物體解除父子關系。
FindFinds a child by name and returns it. 通過名字查找子物體并返回它。
IsChildOfIs this transform a child of parent? 這個變換是父級的子物體？
