MonoBehaviour.OnBecameVisible()

Description

OnBecameVisible 在渲染器变为对任意摄像机可见时调用。

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.

using UnityEngine;
using System.Collections;

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

OnBecameVisible 可以作为协同程序使用 - 在函数中使用 yield 语句即可。 在 Editor 中运行时，场景视图摄像机也会导致调用该函数。
