PHP Code:


		
			
function checkPath(ox, tx, oy, ty) {

  temp.nxy = {(tx + 23.5/16) - (ox + 23.5/16)

              (ty + 31.5/16) - (oy + 31.5/16)};

  temp.dist = (nxy[0]*nxy[0] + nxy[1]*nxy[1])^0.5;

  temp.ow = false;

  

  for(temp.i = 0; i < dist; i ++) {

    if (onwall2((ox + 23.5/16) + ((nxy[0]/dist) * i),

       (oy + 31.5/16) + ((nxy[1]/dist) * i), 0.5, 0.5)) {

      ow = true;

      break;

    }

    i ++;

  }

Perhaps a system could be created to transfer complex calculations to a single client that has the NPC loaded and the calculating client would shift between the various clients that have it loaded, and fall back on the NPC-Server if none have it loaded.

Just a thought.

I know I'm a little late but wouldnt something like this do the trick

PHP Code:


		
			
public function CheckPath(x, y, dx, dy)

{   

   temp.check = 0;

   temp.checkrate = 1;

   

   temp.distance = distance(x, y, dx, dy);

   temp.angle = getangle(dx - x, dy - y);

   

   while (temp.check < temp.distance)

   {

     temp.checkx = int(x + (temp.check * cos(temp.angle)));

     temp.checky = int(y + (temp.check * -sin(temp.angle)));

     

     if (onwall(temp.checkx, temp.checky))

     {

        temp.onwallcounter += 1;

     }

   

     temp.check += temp.checkrate;

     

     sleep(0.05);

   } 

  return temp.onwallcounter;

}
