Description 描述

Update is called every frame, if the MonoBehaviour is enabled.

当MonoBehaviour启用时，其Update在每一帧被调用。

Update is the most commonly used function to implement any kind of game behaviour.

Update是实现各种游戏行为最常用的函数。

JavaScript:

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

C#:

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

In order to get the elapsed time since last call to Update, 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Update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。
