Transform 变换

Namespace: UnityEngine

Inherits from: Component

Description 描述

Position, rotation and scale of an object.

对象的位置、旋转和缩放。

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:

场景中的每一个对象都有一个Transform。用于储存并操控物体的位置、旋转和缩放。每一个Transform可以有一个父级，允许你分层次应用位置、旋转和缩放。可以在Hierarchy面板查看层次关系。他们也支持计数器（enumerator），因此你可以使用循环遍历子对象。

localScale	The scale of the transform relative to the parent. 相对于父级变换的缩放。
localToWorldMatrix	Matrix that transforms a point from local space into world space (Read Only). 变换点的矩阵从局部坐标到世界坐标（只读）。
lossyScale	The global scale of the object (Read Only). 该对象的整体缩放（只读）。
parent	The parent of the transform.  该变换的父对象。
position	The position of the transform in world space. 在世界空间坐标transform的位置。
right	The red axis of the transform in world space. 在世界坐标空间，变换的红色轴。也就是x轴。
root	Returns the topmost transform in the hierarchy.  返回最高层级的变换。

Functions 函数

DetachChildren	Unparents all children.、 所有子对象解除父子关系。
Find	Finds a child by name and returns it. 通过名字查找子对象并返回它。
GetChild	Returns a transform child by index. 通过索引返回一个变换的子对象。
GetSiblingIndex	Gets the sibling index. 获取该对象的同级索引。
InverseTransformDirection	Transforms a direction from world space to local space. The opposite of Transform.TransformDirection. 变换的方向从世界坐标转换到局部坐标。和Transform.TransformDirection相反。
InverseTransformPoint	Transforms position from world space to local space. The opposite of Transform.TransformPoint. 变换位置从世界坐标到局部坐标。和Transform.TransformPoint相反。
