MonoBehaviour.OnEnable()

描述

当对象被启用并处于活动状态时，将调用此函数。

由于此函数在对象启用时执行，因此它将在每次进入播放模式（对象启用）时执行。

// Implement OnDisable and OnEnable script functions.
// These functions will be called when the attached GameObject
// is enabled.
// This example also supports the Editor. The Update function
// will be called, for example, when the position of the
// GameObject is changed.

using UnityEngine;

[ExecuteInEditMode]
public class PrintOnOff : MonoBehaviour
{
    void OnDisable()
    {
        Debug.Log("PrintOnDisable: script was disabled");
    }

    void OnEnable()
    {
        Debug.Log("PrintOnEnable: script was enabled");
    }

    void Update()
    {
#if UNITY_EDITOR
        Debug.Log("Editor causes this Update");
#endif
    }
}

注意： OnEnable 不能是协程。
