Physics #3
Description
Need to create a method to create a more physically realistically way of moving materials. Downward movement is already physically realistic gravity works. This is in relation to solids mainly, as liquids can move horizontally and vertically. Gases also probably won't follow physically realistic rules. Courtesy of marf when something is below a solid material, convert some of the vertical velocity to horizontal velocity. Also whenever on the bottom of the screen or on top of other materials then friction is applied which should reduce horizontal velocity. Probably have to get rid of update side down method for more physically realistic behavior.
