In the OP, it says, "I have not tested it in anything but Counter-Strike: Source, but I can't see why it wouldn't work. Originally I had this marked as a CS:S plugin, but I changed it to Any after others said it works." I just made this bold.

DOD:S apparently uses a different jump event. CS:S and HL2DM are the games so far reported to work, as they both use "player_jump" for jumps.

The plugin could be made to work simply by replacing "player_jump" with whatever DOD:S's jump event is. I may look into fixing this later, but I don't have DOD:S installed, nor do I play it.
