[unreal] 使用Mixin方案，使用super会出现错误

    GetDerivedStaticClass(): UE.Class {
        if (!this.classDerivedByMixin) {
            ALog("Haven't Mixin");
        }
        return this.classDerivedByMixin.StaticClass();
    }

export default new MixinSuperTemplate();

在gamemode里Mixin后通过GetDerivedStaticClass(),spawnActor()。根据示例理解写的，是哪里理解有问题吗

js调用父类，父类是UE类型，UE的规则是调用子类，于是又调用js，所有死循环。

其次，mixin不是继承，早在mixin出来前继承已经存在几十年了，如果mixin是继承，就没必要折腾个新别名。

我的例子用得也是一个POD类型。

如果用ts类mixin了一个bp类，是不是就没办法在ts的方法里面调用被mixin的方法了？
