Pellet gun is working.
Different kinds of bullets look different
Added collision with bullets

Entity takes damage from enemy bullet, and bullet is cleaned up
Added from = "any" state transitions

- from any state to damaged if entity has damage
[WIP] trying to get the damage slide working

When megaman is hit by an object or enemy, he slides away from
it.
Got it!

The direction and facing are based off the centers of the colliding
objects.
Megaman is temporarily invulnerable after being shot

Bullets pass through him, he flickers and flashes
Deactivate the x_buster when megaman is damaged
