I have a PNG image with a transparent background but when I get it to move across the
screen, it displays a white background. How do I stop this?
Are you testing your game on your iPhone with GameSalad? If so, it's a known glitch that happens when testing on the "iPhone GameSalad viewer"... it doesn't happen on the "Android GameSalad viewer"
It also does not happen when testing on the "Computer GameSalad Viewer"
I'm just running it on the GameSalad developer system and it's showing a white background.
by "GameSalad developer system" you mean on your computer? or on your iphone or android (yes, via gamesalad viewer obviously)
I mean my PC (running on Windows 7)
