MonoBehaviour.OnBecameVisible 当可见

function OnBecameVisible () : void

Description描述

OnBecameVisible is called when the renderer became visible by any camera.

当renderer(渲染器)在任何相机上可见时调用OnBecameVisible。

This message is sent to all scripts attached to the renderer. OnBecameVisible and OnBecameInvisible is useful to avoid computations that are only necessary when the object is visible.

这个消息发送到所有附在渲染器的脚本上。OnBecameVisible 和 OnBecameInvisible可以用于只需要在物体可见时才进行的计算。

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void OnBecameVisible() {
		enabled = true;
	}
}

// Enables the behaviour when it is visible
// 当可见时开启行为
function OnBecameVisible () {
   enabled = true;
}

OnBecameVisible can be a co-routine, simply use the yield statement in the function. When running in the editor, scene view cameras will also cause this function to be called.

OnBecameVisible可以被用作协同程序，在函数中调用yield语句。当在编辑器中运行时，场景面板相机也会导致这个函数被调用。
