有两个蓝图Blueprint1(图片是Blueprint1内容) 和Blueprint3(里面是空的什么都没有),两个都放进关卡运行只会打印1, 为什么下面那个事件不能执行?(上面是自定义事件手动绑定到销毁时事件分发器,下面的事件是通过右侧的细节面板里的事件创建).(我只有初中文化今年30+了,有点搞不懂,我不是已经通过get actor of class拿到对象Blueprint3在关卡中的一个实例了吗?)

如果把变量Blueprint3设置为可编辑实例.然后在关卡细节面板中手动指定Blueprint3对象这时候两个事件都会运行,并打印1和3.

紧接着如果这时候继续设置-取消Blueprint3变量可编辑实例-编译-打开Blueprint3变量可编辑实例-编译-这时候可以看到关卡细节面板Blueprint3这里已经显示为无了但是运行时还是会打印1和3.

这东西到底要怎么去理解?

我的理解,通过细节面板创建的事件引擎已经帮我绑定到事件分发器了吧?而且我手动绑定也会报错
