* The module will automatically use the relevant function depending
* on what game mod is loaded. You only have to tell it to do the damage.
* -
* Be VERY VERY careful. I check _NO_ bounds in any of the natives
* Also, these call the game's private function, and I do not have
* the time nor desire to figure out the quirks of each mod's function
* -
* The USE natives haven't been tested yet, but should work!
* -
* The only mod I tested the windows version of takedamage
* for was cs 1.6. It's much easier for me to test linux.
