Problem

During the development of the main menu, I ran into an issue where buttons, like "Play" or "Quit," were not responding when clicked. It all compiled fine, but the function was never being called when I pressed the button. I honestly thought maybe my button wasn’t set up correctly or that the binding was broken somehow. This was a serious problem because players would be unable to start the game or exit properly from the menu, leaving them stuck at the very first screen. For end users, that would make the game unplayable, so it was a high-priority fix.

Solution

After tracing the problem, I found that the issue wasn’t with the menu setup itself but inside my ButtonWithText.h file. The HandleClick() function was bound to the button, but because it wasn’t marked with UFUNCTION(), Unreal’s reflection system didn’t recognize it for delegate binding. Adding UFUNCTION() directly above the void HandleClick() declaration solved the problem immediately. With this fix, button presses now register properly, allowing players to start or exit the game without issues.
