Collision Editor: Editing tools

Collision ID's
Use this interface to select which collision ID to draw.
You can also press a number on the keyboard to select ID's quickly.
The ~ key selects ID zero.
  In most games, collision ID 0 is passible, and collision ID 1 represents walls. All the other collision values represent whatever the game wants them to. It'll vary from game to game. But most values go unused.

You could program a game that uses one ID as water and another for harmful objects like lava.
A platformer game could use an ID to define one-way ledges.
