| ACTORCOL_ALL = ACTORCOL_NO_Y_MOVE | ACTORCOL_GRAVITY | ACTORCOL_BIT2 | ||
| ACTORCOL_NO_Y_MOVE = FLAG_BIT(0), // When _not_ set, an actor can move vertically. Set for non-flying enemies. | ||
| ACTORCOL_GRAVITY = FLAG_BIT(1), | ||
| ACTORCOL_SLIDE_RESPONSE = FLAG_BIT(2), // Actor will "slide" along a wall that they collide with. This is generally set for flying enemies and bosses. |

Nice, I never got around to naming all of the flags properly.

I worked out what is going on in the actor collision code. I've renamed members in the
CollisionInfostruct that looked like they still had provisional namesbotOffset --> stepUpHeight (max step height that can be climbed up by the actor)
yPos --> stepDownHeight (max step height that can be climbed down by the actor)
These have been made moddable.
I worked out that bit 2 of ActorCollisionFlags causes actors to slide along a wall that they collide with, so have named it and also made it moddable.
Also made it possible to set mod logics to use the trooper alert sounds.
