Sorry, but your source codes will not work, please completely remove your current source code from Platform and BuyArcher before adding the source code given in this post. As I understand, you want to click on a platform and after that you want to click on a button ("BuyArcher") and then a tower has to appear on the platform that was clicked earlier.

Currently, there is nothing that does this in your source code. 1.

The left and right arrows to turn, up to accelerate and, although I didn't test it well, down is probably to decelerate. I cannot tell what mechanism controls the drag off the track, but possibly background color testing or maybe the center of the track is expressed in formulas and deviation from the center by a specified amount will trigger the drag.

I think I got it solved. I tried greenfoot version 3.6.0. The problem still occurred. Then I decided to switch to ubuntu. I installed greenfoot on it. Now in it if I delete my actor's subclass the problem does not occur. I thank both of you for helping me!
