Need help with shoot()

[khortez]

I have tried testing it to see if it would shoot a arrow or anything, but it was a no go, I don't even see a shadow being shot. so if anyone could point out what i need to do to get this working, it would be nice, thanks in advance.

Also, additional constructive criticism about the script i have would be nice too. like what i should do instead, or something i should not have done on it would be helpful.

PHP Code:

//#CLIENTSIDE
function onCreated() {
  this.equip = false;
  this.gunout = false;
}

function onKeyPressed(code, key) {
  if (key == "d") {
    if (this.gunout == true) {
      onFire();
    } else {
      onGani();
    }
  }
  if (key == "a") {
    this.equip = this.gunout = false;
    setani("idle", null);
    replaceani("idle", "idle");
    replaceani("walk", "walk");
    player.chat = "Gun off!";
  }
}

function onGani() {
  this.equip = true;
  setani(this.gani_idle, null);
  replaceani("idle", this.gani_idle);
  replaceani("walk", this.gani_walk);
  player.chat = "Gun on!";
  this.gunout = true;
}

//problems below

function onFire() {
  player.chat = "Firing!";
  setani(this.gani_fire, null);
  setshootparams("arrow", player.account);
  temp.angle = getangle(vecx(player.dir), vecy(player.dir));
  temp.zangle = pi / 4;
  temp.power = 1.5;
  shoot(player.x, player.y, player.z, temp.angle, temp.zangle, temp.power, "arrow", "barrow0.png");
} 


also, whats that second parameter in setani()?
