And the numbers represent which target it goes to. I couldn't figure out how to make it stop increasing.

If the target for a projectile is fixed, why did you add lines that change the number?

Greenfoot wont tell me what's wrong

By Ran, with 1 reply.
Replied to by danpost, over 6 years ago:

Greenfoot ignores any attempt I make to compile a class, thus leaving it unusable, but also refuses to tell me which code isn't working. It shows me nothing as missing an element or not formatted correctly.

Sometimes closing the greenfoot application and restarting it will help.
