> The door and the guard are both physical objects, both have momentum, they impart an impulse on each other

I wonder if the term "impulse" here has any connection to the various impulse commands available in the source engine. I remember using "impulse 101" and causing havok in the opening plaza area. Spawning zombies on the roofs, sending them after the combine, etc.

		Right, I was just wondering if the developers repurposed the term impulse from the physics engine when creating console commands. "impulse 101" is a common cheat to give all weapons with ammo, but why not "give" or "player.addItem" or something? Just a curiosity.
