MonoBehaviour.Update 更新

function Update () : void

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。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void Update() {
		transform.Translate(0, 0, Time.deltaTime * 1);
	}
}

// Moves the object forward 1 meter a second
// 以每秒1米的速度向前移动物体
function 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。
