Mouse Over not working in build version

Dear Unreal Community,

Our mouseover event only got triggered in -editor and in -game mode. Whenever we build a shipping version of our game, this event is never trigger. There’s absolutely nothing different to prevent this from happening in our codes.

So I’m wondering if anyone has any problem with this like us?


Hi KillerPenguin,

Have you been able to reproduce this in a clean project with no additional content? Additionally, please ensure that you have the game mode, playercontroller, pawn, and HUD set to your game specifics in both the Editor Preferences window and the world settings pane. Thank you!

We used c++ to set up all those thing and all version are sharing the same codes. The only code that didn’t work in the built version was the mouse event.

ps. We wrote our own mouse over code now, but just reporting bugs in any case.

HI KillerPenguin,

What I mean is, in a clean, blank project with nothing else in it, are you able to reproduce this bug? For instance, if you create a brand new blank code project and attempt to use the mouse over code, does the same error still occur?

Hi KillerPenguin,
