I'm not quite sure what you're asking, but I think you mean that you're trying to trigger NPCs when they've been attacked.

Let's create a simple function for it..

PHP Code:

// put this in a class like func_damage so you can reuse it
function attackNPCs(temp.attacker, temp.attackX, temp.attackY, temp.attackRadius) {
  for (temp.npc : findAreaNPCs(temp.attackX - temp.attackRadius, temp.attackY - temp.attackRadius, temp.attackRadius * 2, temp.attackRadius * 2)) {
    // you could do proper radius checking rather than a square with
    // length of 2*radius, but this is easier and generally sufficient for your needs
    temp.npc.trigger("attack", temp.attacker); // tell the NPC it's been attacked
  }
} 


Now in any NPCs, you can do

PHP Code:

function onAttack(temp.attacker) {
  this.chat = "I was attacked by " @ temp.attacker.nick @ "!";
} 


Then in your weapon, you can just do this:

PHP Code:

function onCreated() {
  this.join("func_damage");
}

function onActionServerside(temp.command, temp.x, temp.y) 
{ 
  switch(temp.command){  
    case "attack":
      this.attackNPCs(player, temp.x, temp.y, 1);
    break;
 } 
}
