MonoBehaviour.OnBecameVisible()

Description

OnBecameVisible 在渲染器变为对任意摄像机可见时调用。

该消息将发送到附加到渲染器的所有脚本。 OnBecameVisible 和 OnBecameInvisible 有助于避免仅在对象可见时才需要进行的计算。

// Enables the behaviour when it is visible

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void 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.
