- - - Updated - - -

how do you use that code?

Lua.
Put it to inf.txt , then save it as lua and put it to Gmod lua folder.
Then in game bypass lua,
and execute. (lua_openscript_cl inf.lua)

Get Rekt.

They're messing with you. Running cam.End3D() crashes your game. In response to your request, go and look at addons. A vast majority of them are exploitable.
