Arc hitbox system for weapons triggering three times per swing.

You might also want to move some of that code to functions. I.e:

PHP Code:

function sendTrigger(pl) {
  triggeraction(pl.x+0.5, pl.y+0.5, "Damage", this.effects, player.account, {temp.damage, temp.criton}, temp.accuracy, "Physical", 100, temp.armorpierce, temp.attackerlevel, ax, ay, az, ad); 
  if (client.showhits){ 
    triggerserver("gui", this.name, "putnpc", "testblock",pl.x+0.5, pl.y+0.5); 
  }
} 


Other functions may include:

PHP Code:

function inHittingRange(pl, maxdist) {
  if (pl == player) {
    return false;
  }
  if (dist(player.x + 1, player.y + 1.5, pl.x + 1, pl.y + 1.5) <= maxdist) {
    if (player.dir == 0) {
      if (pl.y < player.y + 0.5) {
        return true;
      }
    }
    else if (player.dir == 1) {
      if (pl.x < player.x + 0.5) {
        return true;
      }
    }
    else if (player.dir == 2) {
      if (pl.y > player.y + 0.5) {
        return true;
      }
    }
    else if (player.dir == 3) {
      if (pl.x > player.x + 0.5) {
        return true;
      }
    }
    return false;
  } else {
    return false;
  }
}

function inParty(pl) {
  return (pl.account in clientr.party);
} 


Also I would store the tokens in it's own variable, for clarity reasons and it's slightly more efficient.

Your code can then be re-factored to:

PHP Code:

temp.weapondata = wdata[5].tokenize(",");
temp.weapontype = temp.weapondata[1];
temp.weapondist = temp.weapondata[2];
if (temp.weapontype == "arc") {
  for (temp.pl: findNearestPlayers(player.x, player.y)) {
    if (!inParty(temp.pl)) {
      if (inHittingRange(temp.pl, temp.weapondist)) {
        sendTrigger(temp.pl);
      }
    }
  }
}
