菜单栏GameObject中的Break Prefab Instance ，脱离与Prefab的关联。

菜单栏GameObject下的Clear Parent，可以脱离父子关系。

Ctrl + D 复制

按住Ctrl拖动，1米间隔

[System.Serializable]设置为可序列化属性

Enemy Spawner

public static private

小Bug：敌人孵化器脚本中的static变量在场景重载时会变-1；

public static int countEnemyAlive = 0;

修复private void Awake()
    {
        countEnemyAlive = 0;
    }

直接替换材质球：effect.GetComponent<Renderer>().material = materialSelf;

    void UpdateEnemys()
    {
        enemys.RemoveAll(n => n == null);
    }

搞定。

设置Physic碰撞矩阵即可。

public static Transform[] position;

positions = new Transform[transform.childCount];

for (int i = 0; i < positionLength; i++){

}

coroutine

添加事件时注意选上面的dynamic bool。

OnDestroy 会在 GameObject.Destroy(this.gameObject); 自动被调用。
