Please correct me if I'm wrong:
If I'm right, injecting is purely clientside
That's why you add 'cl' to the end of the open script command, it stands for cliant side
A dll, which you would inject into your client, wouldn't have any effect on the server.
I could understand a lua script doing this though
But then again, I'm a newbie too.
EDIT: I realized I totally contraticted myself.
Err, I meant a serverside lua script could, not a client side one, and unless the server is owned by owners that don't know how to own a server, you can't open serverside lua scripts.
