hopefully somebody can help me.

greets passie

I dont understand it fully, but i think this is what you need.

PHP Code:

---

<?php
$coords = array("1,2", "1,4", "1,8", "1,0", "2,2", "2,6", "2,0", "3,5", "3,6", "3,7", "4,9", "5,3", "5,9", "6,3", "6,7", "7,3", "7,9", "7,0"); //which are restricted 
$rand1 = rand(1,70); //1-70
$rand2 = rand(0,9); //0-9

$searching = false;

while($searching){
    $newcoords = $rand1.",".$rand2;
    if(in_array($newcoords, $coords)){
        $rand1 = rand(1,70); //1-70
        $rand2 = rand(0,9); //0-9     
    }else{
        $searching = true;
    }
}

echo $newcoords;

?>

sorry for my bad english dunno what i have today.

but i mean the numbers in $coords are restricted which are not allowed.
because there are tree's on the map on these coordination s

the coords which are generated it for the player house on the world.
but your script don't return any result

My bad, im sorry.

PHP Code:

---

<?php
$coords = array("1,2", "1,4", "1,8", "1,0", "2,2", "2,6", "2,0", "3,5", "3,6", "3,7", "4,9", "5,3", "5,9", "6,3", "6,7", "7,3", "7,9", "7,0"); //which are restricted 
$rand1 = rand(1,70); //1-70
$rand2 = rand(0,9); //0-9

$searching = true;

while($searching){
    $newcoords = $rand1.",".$rand2;
    if(in_array($newcoords, $coords)){
        $rand1 = rand(1,70); //1-70
        $rand2 = rand(0,9); //0-9     
    }else{
        $searching = false;
    }
}

echo $newcoords;

?>

Store your coordinates as integers:

PHP Code:

---

$point = $x << 16 | $y;

Just saying.. it'll make life easier.
