[Request/Help] Teleport Scipt

Does anyone know of a working /tpcoords command? Looked all over cant find one.

RegisterCommand("teleport", function(source, args, raw)
    if ( args[2] == nil or args[3] == nil or args[4] == nil) then
        print("Invalid values")
    else
        SetEntityCoords(GetPlayerPed(-1), args[2], args[3], args[4])
    end
end, false)

Just paste this in client.lua?
