ok, i would on my own server but i dont even know how to write a script, much less for something that doesnt even hook to anything that isnt gta5.exe is what im trying to say.

It's an external program, not an dll injector

something similar to the injector above except it hooks to fiveM.exe nstead of gtav.exe
