描述

应用相对于世界坐标系的变换。

使用它可通过世界坐标对 GameObject 应用变换。这意味着 GameObject 的变换是通过世界空间而不是 GameObject 的本地空间改变的。要变换 GameObject,并且考虑 GameObject 的旋转,请使用 Space.Self

//This example shows the difference between using Space.world and Space.self. Attach this script to a GameObject
//Enable or disable the checkbox in the Inspector before starting (depending on if you want world or self)
//Press play to see the GameObject rotating appropriately. Press space to switch between world and self.

using UnityEngine;

public class Example : MonoBehaviour { float m_Speed; public bool m_WorldSpace;

void Start() { //Set the speed of the rotation m_Speed = 20.0f; //Rotate the GameObject a little at the start to show the difference between Space and Local transform.Rotate(60, 0, 60); }

void Update() { //Rotate the GameObject in World Space if in the m_WorldSpace state if (m_WorldSpace) transform.Rotate(Vector3.up * m_Speed * Time.deltaTime, Space.World); //Otherwise, rotate the GameObject in local space else transform.Rotate(Vector3.up * m_Speed * Time.deltaTime, Space.Self);

//Press the Space button to switch between world and local space states if (Input.GetKeyDown(KeyCode.Space)) { //Make the current state switch to the other state m_WorldSpace = !m_WorldSpace; //Output the Current state to the console Debug.Log("World Space : " + m_WorldSpace.ToString()); } } }
