Define two pairs of coordinates on the map. build a relation between the game-coords and the pixels of the image.

e.g.

Code:

InGame -> Pixels
0|0 -> 3000|200
3500|250 -> 4300|800

Having these, you can calculate a conversion factor for "pixels per ingame-meter" and an offset.

i should create an alrgorithm to find any location based on those 2 dots relations, but can you ellaborate more a littile bit?

I have a cpp-example for the translation. A friend of mine made it: [Only registered and activated users can see links. Click Here To Register...]
