Thanks for the info @Tanoshi , I bought the script and changed the sh_configs.lua to adapt and now I can spawn the signs, yippee ^^
I think I'll follow your lead on that slot machine as well.
I have a new issue, I want to use the code(below) found in the sh_configs.lua that allows you to buy from the Shop tab in F1, but I dont know how I set it to spawn a vehicle(A simfphys vehicle)
nut.bent.add("nut_checker", "models/props_wasteland/interior_fence002e.mdl", "weaponChecker", 2, 1000, onlyLaw)
I found this command for simfphys, but I dont know how to incorporate this into the shop tab seeing as the above code only accepts entities.
