No, what i mean is that if you click twice within a certain number of frames, it counts that as a double click. Since your framerate is so low, it is very easy to click twice within the required number of clicks.

Ah, that must be the problem. Since there is so much time between frames, the counter is counting down very slow, so when you click on it twice, even though you might have clicked on it within an interval of 2 seconds, only 3-6 frames, and it counts that as a double click. Perhapse i will change it to use actual system time...

Hmmm, are you only clicking once? I am trying this myself on all different objects and across all different levels, fast clicks, slow clicks, and i cant get it to reset the object. Is anybody else having this problem? Perhaps the game is running really slow and getting low framerate?

Very nice! I like placing trash cans, the 3D is so fun! But i got an error when moving the trash can near the center java.lang.ArrayIndexOutOfBoundsException: 10 at Park.getObjectsAtTile(Park.java:329) at Park.act(Park.java:182) at greenfoot.core.Simulation.runOneLoop(Simulation.java:332) at greenfoot.core.Simulation.run(Simulation.java:178) :(
