I have been trying to learn more about Pixel Based Movement, because it, frankly, looks sexy in a game, and I am using a 64x64 base and need it. I am having troubles learning it, so I used Cody123100's Pixel Based Movement Library, and am coming up with a blank. The movement looks great; but I am having 2 issues that I think would be better resolved if I understood how to make my own Pixel Based Movement system.

1. The density is not working. In the library, he has a variable called dense, that, in his demo, works just fine. But when I set the dense variable to 1 on any of my /mob or /objs, I can still walk over them in-game.

2. The default movement state is not working. I walk around with the same icon_state all the time. I saw EbonShadow's demo, but I would like my person to be standing straight while not moving, and stepping like normal when moving.

Is there any way I can do this without changing any of my icons?
