新建了个Demo，默认玩家使用鼠标控制摄像头(usePawnControllerRotation=true)，当玩家与NPC交互后，出现选择项，同时禁用鼠标控制摄像头（usePawnControllerRotation=false），显示鼠标指针(showMouseCursor=true && EnableClickEvents=true && EnableMouseOverEvents=true)。但是鼠标无法直接和选项进行交互（无法出发 OnHovered，或者 OnClicked 事件），必须鼠标点击一次左键或者右键后（这个感觉有点像，鼠标失去了editor的焦点），鼠标才可以正常交互（能正常触发 OnHovered 或者 OnClicked）…

请教这个问题该如何解决

设置完显示鼠标光标后，还需要设置输入模式( Set Input Mode UI Only )并直接引用需要对焦的UI，退出相应UI后需要设置回去( Set Input Mode Game Only )

其实你查一下官方文档里的showMouseCursor，就会有这个说明，当然不详细，但是能理解的

感谢回答，是我想多了，不需要禁用 usePawnControllerRotation，直接设置 SetInputModeGameAndUI 就行~
