I've been working on a project, and whenever I click the run button it does nothing. It was working fine before...
Is there some kind of troubleshoot for this or something? Any help would be much appreciated. :)
If the run button doesn't do anything the game probably starts and you directly get an error or an exception which causes the game to stop.
If there is an exception or an error it'll be shown in a new window.
In this window there probably is a link that shows where the exception/error occours.
If you can show us the code that causes the problems we probably can help you to fix this problem.
Chances are you need to edit your world constructor code. Start by commenting out everything after the 'super' call; then, line by line (or group by group of lines) uncomment them and compile after each uncommenting action. This should let you know what is causing the problem (when it finally occurs again).
