It works on gmod which uses Lua to code all its functions but it is really good and quite amusing to fall from great heights as a ragdoll. especially when you face plant the ground
I know Gmod is way different and much more advanced plugin wise and is much less hacky than sourcemod.
Still I figure it is possible.
just have to figure out how to make the camera do what you want when someone dies rather than automatically 3rd personing your corpse.
and if you think about it... when you die it follows your ragdoll with third person which means its following the client side ragdoll rather than a server side calculation for the corpses position.
