Hello, I'm making a game for my school project and in this game I have made it so I can spawn a map made out of tiles. The thing is when I make a larger map like 60*60 tiles in size the screen just freeze and after a while it pops up the map. I would want it so I could come into a loading screen with a loading bar so I could see the progress instead of making it seem like the game isn't responding anymore? Would really appreciate help!
