5. 总结 问题:在构造函数中绑定时,OnComponentBeginOverlap 事件未触发。 原因:在构造函数中绑定事件时,组件尚未完全初始化和注册。 解决方案:将事件绑定移至 BeginPlay,以确保组件准备好进行交互。 结果:现在重叠事件如预期般触发,无需蓝图修改。 6. 建议 避免在构造函数中绑定事件:在 Unreal Engine C++ 中,避免...

By default a 'begin_play' and a 'tick' method are expected (they will be automatically taken into account if found). In addition to them an 'automagic' system for defining event is available: defon_actor_begin_overlap(self,me,other_actor):passdefon_actor_end_overlap(self,me,other_actor)...
bind_event('OnActorBeginOverlap', a_funny_callback) You can obviously bind to Event Dispatchers too. Triggering events is basically like calling functions, self.uobject.call('OnActorBeginOverlap') will be more than enough. If you want to map events from a blueprint to a python function, ...
Triggering events is basically like calling functions, self.uobject.call('OnActorBeginOverlap') will be more than enough. If you want to map events from a blueprint to a python function, the best thing to do is using the 'python call' blueprint functions exposed by the various plugin clas...
Mac Metal 现在能够默认开启 Shader Model 5 的支持了。这将使得所有 Mac OS X 10.11.6 的 Metal 上可用的特性都能在虚幻引擎 4 中得以使用。实现了 RHI 线程和平行调度分发渲染指令。 对Metal 计算 shader 的支持。 支持在 AMD GPU 上的异步计算。 启用了原先在 Mac 上不可用的一些高阶渲染特性,包括: 高...
