我目前正在学习Unreal并使用C ++,并且在创建碰撞箱时收到“错误C2248:'UPrimitiveComponent :: bGenerateOverlapEvents':无法访问在类'UPrimitiveComponent'中声明的私有成员 该错误显示在ShipController.cpp文件的第18行。
阅读时,建议不要使用'bGenerateOverlapEvents'来使用'SetGenerateOverlapEvents',但是,尽管编译正确,但碰撞盒无法正常工作。

我希望输出结果是当EnemyController类的对象触摸ShipController类的对象时,游戏将暂停,并且Shipship类的对象将被隐藏在游戏中。
答案 0 :(得分:0)
使用SetGenerateOverlapEvents(true);
代替bGenerateOverlapEvents = true;
确实有效。
由于某种原因,我将对象设置为不同的高度,并且碰撞盒没有碰撞,这就是为什么它似乎不起作用的原因。
感谢您的评论和建议!
