See my post here:
viewtopic.php?f=3&t=3463I solved the problem mostly. Now you can have kits disappear after they spawn from a soldier. It involves adding mobile physics to the kit and despite adding mobile physics usually being a big no no in Server Side modding, it seems to work on kits server side. Most importantly, you can't use the standard mobile physics setting as it has no effect. It must be the "set" version. (ObjectTemplate.
sethasMobilePhysics 1) Since oddly the standard one has no effect.
However the kit still is technically on the map (it just falls through the ground so that nobody can pick it up), so for those who are trying to get kits with spawn points on them to go away, then this probably won't be of use. But for all other purposes it should do the job. Perhaps just add the spawn point to a weapon other then the primary weapon (the one that kit shows when on the ground). Try adding it to the knife or the hand gun. Since kits only use one weapon for visible use when on the ground.
If you do use this to get rid of dropped kits, be sure to add the "ObjectTemplate.holdobject 1" code to make any kits you spawn on the map stay in place, since it will effect map spawned kits as well.
