Well the San Andreas map is 6000*6000, so you should just calculate the half of the coordinate.

XMin -2989.5361
XMax 2977.8582

YMin -2942.8245
YMax 2989.5361

The problem is to onvert it.

Because 0.0 beging into the left top in the image.

But samp coord 0.0 is into los santos.

like this?

Код:

MapIconPosX=(HousePosX+3000)/2;
MapIconPosY=3000-(HousePosY+3000)/2;

edit: ah you got it working

old: hm... may we get 1 or 2 house coordinates? perhaps the 2 red houses at santa maria beach?
the position parameters are clear: -3000 to 3000 on both axis at the gta map, offset by 3000 to result in positive coords, scaled down /2 to fit the picture size, and the y-axis inverted. i clicked the link, and the houses in santos looks good... weird.

Hi, sorry for possibly jacking your topic but, i've been wondering how to do this for a long time, would you or anyone else be able to help me? Thanks.

What I need is, basically, the same as the OP. I've used the code you provided Babul, but, I don't think it's work as it should! Here's what I currently have;

Код:

$Query = mysql_query("SELECT * FROM `houses`");
while($Row = mysql_fetch_assoc($Query)) {
	$MapIconPosX=($Row['out_X']+)/2;
	$MapIconPosY=3000-($Row['out_Y']+3000)/2;
	echo '<div style="z-index: 2;position:absolute;top:'.$MapIconPosY.';left:'.$MapIconPosX.'; width: 60px; height: 60px;"><img src="images/house-green.gif" /></div>';
}
