Not to forget to mention the greatest issue, lag/ping. But basically, I don't see how it would differ much with you clicking on it, or having something search for it.
From what I've done with various types of Pixel Searching (C++, some Delphi, and some scripting engines like AutoIt or even SCAR) they all seem to work fine. I really doubt a 3 second delay would really be that much, especially when dealing with monsters. If you were talking about PvP, it would be different, but then again, system specifications and also internet connection, etc. would affect it all.
You could have 300 ping on a server (my average
) and someone else might have 475 ping at the time, and so it would basically make no difference whether it's a 3 second pixel search delay or a 500 millisecond, it's still going to suck.
Also, I doubt anybody would really be training on anything higher than what they know they can handle, so a 3 second delay or less wouldn't really matter, unless you can't stand taking 1 damage from a Bandit :P
There are various things out already such as Conquer Partner which seem to do just fine, and I doubt that is very advanced in the whole Pixel Searching methods.
If this was some other game such as Counter-Strike and you were doing a color 'aimbot', which I know LiX has, then I guess it would need to be more technical, but as a fact, Conquer is just like, a point and clicker.
It doesn't take any skills except a strong finger and eyesight...not even good coordination
So what I'm saying, is 300 ping and 500 Milliseconds against 300 ping and 3 seconds of a pixel search delay, isn't really going to matter.
You also have to look at the fact that on average, there is around 3-5 monsters on your screen at the same time, if you're hunting anywhere...especially Elfapes or somewhere like that. You're bound to find one of them in less time than 3 seconds, which really isn't that much at all.
It's not like making a Pixel Searching hunter for you is going to be much different than just clicking a monster yourself, it's doing the same thing, but...
faster. So that means, we all know we can click a monster right now if we were playing and we'd go attack it, even if it did move, we'd go to where it moved...the bot would be doing the same thing at the same speed if not faster...
