RuntimeInitializeLoadType运行时间点枚举

在unity运行的时执行，RuntimeInitializeLoadType运行时间点枚举

   //
    // 摘要:
    //     Set RuntimeInitializeOnLoadMethod type.
    public enum RuntimeInitializeLoadType
    {
        //
        // 摘要:
        //     After Scene is loaded.
        AfterSceneLoad = 0,
        //
        // 摘要:
        //     Before Scene is loaded.
        BeforeSceneLoad = 1,
        //
        // 摘要:
        //     Callback when all assemblies are loaded and preloaded assets are initialized.
        AfterAssembliesLoaded = 2,
        //
        // 摘要:
        //     Immediately before the splash screen is shown.
        BeforeSplashScreen = 3,
        //
        // 摘要:
        //     Callback used for registration of subsystems
        SubsystemRegistration = 4
    }

使用示例

public class HookLuaSetup : MonoBehaviour

#if UNITY_5 || UNITY_2017_1_OR_NEWER
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
#endif
    public static void OnStartGame()
    { 
         GameObject go = new GameObject();
         go.AddComponent();
    }
}

用法:制作的工具初始化，不需要手动挂载mono脚本
