What code do you have in the Auto7 class?

In what class is the 'act' method above? I hope it is not in a class of one of those 7 objects.

That is the problem, then. The act method will run for each object of its class during the time it is in the world. If none are in the world, the code will not execute. Use the 'act' method in your World subclass to perform the duty of randomly spawning objects (add an act method there if you do not already have one there.

Show the code for the World subclass so that the placement of given code can be confirmed to be correct.

You are showing 350, 400 and ???; is it supposed to be 350 (again)?
