Jagged collisions in the physics branch

[Althoumb]

Collisions with the ground aren't smooth--possibly circumvent with rounded rectangles?

I'm not entirely sure what you mean about "not smooth". Should the player be able to slide up onto blocks?

Also, if you plan to use rounded rectangles, I don't think the physics engine will allow you to use java.awt rectangles. You might consider looking into creating 4 dyn4j capsules

[Althoumb]

If you walk along a flat section of ground, you get caught on the hitboxes of the ground, even if it should be a "smooth" slope. It's probably a floating point error, since it appears to happen completely at random while walking in both directions.

We could use capsules, but they don't work for shapes like squares and wide rectangles. I think we could use rounded rectangles, and convert them into dyn4j polygons. We could also use octagons like in the following drawing for performance and simplicity, at the expense of smooth movement.

The hit boxes have been changed in 31234bc. Note that the current implementation causes the character to be launched upwards when it used to get stuck.
