Simple Map Modifier

[taco-man]

im not quite sure i understand you correctly, but but heres a slightly simplified version of the function i wrote for the site that takes the pathfind location and zonerect and gives you the x,y coordinates on the map
incase mean is lost in translation this function is
need: pathfind location, zonerect
returns: x,y location on map.

PHP Code:

function GetCoords($PathfindLocation, $ZoneRect){
            //Assume Map images size
            $MAP_1x = 436;
            $MAP_1y = 506;
            //the 2 below should always be zero
            $MAP_0x = 0;
            $MAP_0y = 0;
            //Set Icons Width and height
            $IconW = 12;
            $IconH = 12;
            //split the pathfind location into 2 variables (assumes there is no Z coordinate given in pathfind location
            //normally i have a check that splits it differently depending on if there is 1 comma or 2.
            list($LOC_x, $LOC_y) = explode(",",$PathfindLocation);
            //split the zonerect up so i can use each value
            list($LOC_0x, $LOC_0y, $LOC_1x, $LOC_1y) = explode(",",$ZoneRect);
            $LOC_0x = $LOC_0x * -1;
            //Calculate WDPP_X and WDPP_Y
            $wdpp_x = ((-$LOC_1x - $LOC_0x) / $MAP_1x);
            $wdpp_y = (($LOC_1y - $LOC_0y) / $MAP_1y);
            //calculate Location
            $MAP_x = (((-$LOC_0x + $LOC_x) / $wdpp_x) + $MAP_0x) - ($IconW / 2);
            $MAP_y = (((-$LOC_0y + $LOC_y) / $wdpp_y) + $MAP_0y) - ($IconH / 2);
            //round the Location so that there are no decimals
            $MAP_x = round($MAP_x, 0);
            $MAP_y = round($MAP_y, 0);
            $xml_loc = "$MAP_x,$MAP_y";
            //return location in format x,y
            return($xml_loc);
            //end calculations
} 


does this help at all?
