You can't do that without having to 'draw' something, as already stated. Be it with directx or else wise.
So obviously, the point of having to 'draw' something, was already made, which I'm not going to do. And most of what your doing, like eiden, breaks all to shit on big updates, like the WvW coming update.. Midnight couldn't even last through the last update yet Unf what did I have to update, the loot address? And what did I need to change on ESP, the highlight? And how hard would it be to port Midnight out of autoit?
You still haven't even realized about using character state + teleport to bypass the banning..
And you still call it wall walk, maybe you should call it something proper like Climb since it involves slope limit and not walls an goes into the climb speed divisor, but you'd notice that if you actually looked at the address your using from my old CT table in midnight. Just saying ;)
