No matter what I do unless I change the window size in the properties the window size does not change. I have use events to change the window size. but nothing happen. I just used simple action no condition whatsoever!
Have you tried this?
At the beginning of the scene > set window size to your window size
I think this stuff doesnโt really work in the preview, or at least I remember having had this problem and never got it working either. Try compiling the game and see whether it work in the actual executable.
