My friend wanted me to get Greenfoot in Eclipse, so I did. He didn't want the run button, but where is the code for creating it so I can remove it?
Also, I need help getting the program to run at all!
Read the documentation that comes in the source bundle on how to build Greenfoot. You should use ant to build and run it (you can use Eclipse's "ant view").
See bluej/doc/HOWTO.make-release for instructions on building BlueJ. You need to build BlueJ as part of the Greenfoot build process.
See greenfoot/doc/HOWTO.release for instructions on building Greenfoot.
That's as much help as I can give - basically you're on your own. Modifying Greenfoot is not for beginners.
