Ok, there must be a way to do this then without creating my own commands, but I don't know how.
I have three SketchMorphs named Moon, Earth, and Sun. I want the Moon to revolve around the Earth, and the Earth to revolve around Sun.
I was going to make a command that would change the moon's X,Y based on the Earth's X,Y, but if I can't create commands that's not really an option.
I guess there's a better way to do this using the commands we already have..any ideas what that way is?
Do you know about arithmetic in EToys? Click the little green arrow pointing to the right, and you can adjust a value using basic arithmetic. So you can do things like:
Moon's x <- Earth's x + Moon's deltaX
