Nothing Happens in my code:P Maze Code Implementation

There seems to be a problem with my code. For some reason my window will not popup for some reason. I will only type in the code that seems to be wrong. No error pops up its just that nothing will happen. I just implemented a random maze generation code in the maps and mapdirector files but nothing happens after i implemented the new code. Please help or at least tell me whats wrong.

Why do you think your map generation code is wrong? If you are getting no errors and the window is not popping up, then there is an error with your window initialization :slight_smile:

Well before I added the Map generation code the program worked well but when i added it it wouldn’t work for some reason. I tested it out both ways with and withought the map generation. The one withought map generation worked and not the one with it.

Does the program just end? If it doesn’t then you have an infinite loop somewhere in there. Try debugging it.
