Description 描述

LateUpdate is called every frame, if the Behaviour is enabled.

当Behaviour启用时，其LateUpdate在每一帧被调用。

LateUpdate is called after all Update functions have been called. This is useful to order script execution. For example a follow camera should always be implemented in LateUpdate because it tracks objects that might have moved inside Update.

LateUpdate是在所有Update函数调用后被调用。这可用于调整脚本执行顺序。例如:当物体在Update里移动时，跟随物体的相机可以在LateUpdate里实现。

JavaScript:

// Moves the object forward 1 meter a second
 
function LateUpdate () { 
	transform.Translate(0, 0, Time.deltaTime * 1); 
} 

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void LateUpdate() {
        transform.Translate(0, 0, Time.deltaTime * 1);
    }
}

In order to get the elapsed time since last call to LateUpdate, use Time.deltaTime. This function is only called if the Behaviour is enabled. Override this function in order to provide your component's functionality.

为了获取自最后一次调用LateUpdate所用的时间,可以用Time.deltaTime。这个函数只有在Behaviour启用时被调用。实现组件功能时重载这个函数。
