And I suppose the direction of the moving object should be reversed for a 3d view perspective, and you could look into removing the cursor for the mouse as well. I think Builderboy2005's Advanced Mouse Control scenario would help: http://www.greenfoot.org/scenarios/2828

The first one occurs as the scenario loads. The second is continuous as it runs after hitting the run button. It seems to be mac related

Thanks, I am aware. This experimentation project has been closed. The blocks not rendering close to the edge of the screen while walking is because of a cut off for how far down the drawing loops go (that don't accurately account for blocks with their base off screen, yet have high enough elevation that should be drawn as they do reach onto the screen). Some related glitches of rendering will be addressed in my future isometric projects.
