Hi guys,
i have some troubles with level “Volcano fighters”. The error message is in line 34 (hero.moveXY): "reads only undefined arguments. I understand the error message, but I don’t know what I could change. I think there might be another error, but I just can’t find it. Can some help me? Thanks a lot!
