Compatibility Options

Odamex offers server operators a variety of ways to maintain compatibility with vanilla Doom behavior or choose other types of behavior.

Allow Dropoffs

This is a latched variable, and only takes effect after a map change.

Usage: co_allowdropoff (0-1)

When enabled, monsters can get pushed or thrusted off of ledges, like in Boom, ZDoom, and other modern engines. Disabled by default to maintain vanilla compatibility.

Real Actor Heights

This is a latched variable, and only takes effect after a map change.

Usage: co_realactorheight (0-1)

When enabled, players, monsters, and other solid objects will be able to pass over or under each other according to their defined pixel heights. When disabled, actors will be infinitely tall and not able to pass over or under each other. Disabled by default to maintain vanilla compatibility.
