Doom3 appears to restrict commands preceded by a _ and allows one _command per bind, this obviously causes problems when scripting.


Weapon Cycle Script
To overcome the single _command per bind (and what appears to be restricted use of _commands in scripts) and until we find a better way here's a very crude workaround; not very usable to be honest.

Use mouse up to cycle explosive weapons, middle mouse button to cycle rapid fire weapons, mouse down to cycle slow fire weapons. To overcome the single command per bind (and restricted use of _commands in scripts) you need to confirm your weapon selection after cycling by pressing W.
