Unity3D的单例模式

RT，具体的模板可用：

public class MyClass : MonoBehaviour 
{
    private static MyClass s_Instance = null;

    public static MyClass instance
    {
        get
        {
            if (s_Instance == null)
            {
                s_Instance = FindObjectOfType(typeof(MyClass)) as MyClass;

                if (s_Instance == null && (Application.isEditor && !Application.isPlaying))
               {
                    GameObject o = new GameObject();
                    o.name = "MyClass Object";
                    s_Instance = (MyClass)o.AddComponent(typeof(MyClass));
                }
            }

            return s_Instance;
        }
    }
     
    // any other methods
    ....
}
