Despite the name, these are not global settings for the entire engine. All these fields only apply to the player, not to any of the monsters.

All these fields are duplicated for the "Running" and "Walking" sections.

A word on modifying physics: Most Marathon players have been at it long enough to "align their brain" to the player's default movement. In addition, Marathon's physics code seems to be tweaked for exactly these values. When I used some altered movement settings for an extended session I felt disoriented and even developed a slight headache. Even a tiny change will feel funny and interfere with the game until the player adjusts. In conclusion, only mess with these numbers if you have a really good reason.

The Physics section uses several different scales, different from the rest of Anvil as well. The conversion factor for speeds is (Player speed)=(Monster speed)/512, but I haven't had too much success precisely matching speeds. Radius and Height are in WU. Angles are probably in Bungie's 512-degree circles, but this is untested.

Possible crashes: Notice that all these numbers are VERY small. While I haven't actually crashed while playing with them, I have experienced some otherwise harmless strange behavior, like walking through doors, smearing, misplaced weapon graphics, random bouncing off walls, and more.
