The scenario stops by itself after I spin the beam around a little. or move the actor some. Do you have it stopping when the beam detects something?

Maybe you should start a discussion, and explain what Greenfoot says it cannot find and give the code around where that highlighted statement is.

If you set the paint order so the beam and the phone are painted last, your robot will only show when the light is on him. setPaintOrder(Telephone.class, Beam.class);

After resetting, I loose the point counter and no asteroids are created. Also, could use a description on what one is supposed to do.
