Hi all :)
So here's what's going on. I'm working on building an Entrapment game, and I started off by simply building an application, with the intent of converting it to an applet later. All went well, and my java program worked fine, so I decided to convert it to an applet.
Here is where I started having problems. So far I have not been able to get the darned program to do anything! Everything compiles fine, but when I run the applet it simply says 'applet loaded', and nothing shows up.
I think that the problem is that it's not repainting, however I have no idea why. As you can see, I have a System.exit line in the repaint method. This should cause the program to generate an error as soon as it is hit during run-time; however no errors are given during either compilation or run-time. What I'm wondering here is why the program doesn't initiate the paint method when repaint() is called?
Sorry for the messy code... look at the init() method and the paint() method and you'll see what I'm talking about...
