So, I began messing around in Clickteam again and started developing a simple, new game.
I'm using some new objects and code I haven't really tried before. In case any of these are the issue, here they are:
-GetRGB / ReplaceRGB
I implemented a feature that would change the ForeGround/BackGround colors when a detector hits them in-game, (it would change the colors of the Active Shapes or Frame Background). However, after getting everything set to go and working...it wouldn't start. I tried restarting my computer (no luck), restarting Clickteam (no luck), and tried other Clickteam apps I've made. Those apps worked, so I don't believe it's Clickteam that's the problem, it's the game itself.
Attached are some images to help you get an idea of what is happening. The rare times I'm able to get in-game, you can't control anything and nothing moves. The Event List Editor might reveal some issue in the code that I have overlooked.
