char position at map for bot

i try to make map control for my bot ( [Only registered and activated users can see links. Click Here To Register...] )
I made it but minimap changes colors in moment of moving char minimally (at first sight, that is not visible). And it is not possible to find same few combination of pixels every time.
Tried to make more pixels start points. Every time if cant find pixel it make another start point and have more start point pixels.
It look first start point, if not found second point if not found another point...
And at last it make another start point every char move if not found all earliest starts point.
it wont be problem if it dont slow down bot :(

Any one know how to do this?

what about reading the /potition coordinates on chat windows?

thinking about that but how can i read it?

I have tried to get the location from the mini-map also a long time ago.

It woundt works, because the mini-map is the same as the big map, just smaller and with a top-down view.

So you can't follow any pixel.

The /potition way works, but has also many bad side effects.
One very important one is: you can't chat with an active bot!
And you risk a ban, if something went wrong and you shout "!\position" all few sec, because someone has chanced the channel by mistake. :D
