How Do I Cange in ags 2.72 the existing quitgui to a quit gui that Made?
No matter I do it Doesn't Change!!
Ehhh....
I'm not really sure what you're asking... my best guess is that you want to turn off a GUI. The way that this is done is by using:
gGuiName.Visible=false;
If you mean the GUI that pops up with QuitGame(1) (like the default Ctrl-Q interaction), then no, you can't change it. However, it's easy enough to make your own (one button that turn it off, one that runs QuitGame(0)) and call that instead.
Actually, you can change the text that's used by altering Global Messages 993-995, if that's any use.
