Why will this only work once and then stop working?

NPC Code:

---

if (created) {

  setshape 1,32,32;

  this.apos = {1.5,0, -0.5,1.5, 1.5,4, 3.5,1.5};

  this.x = playerx;

  this.y = playery;

  this.dir = playerdir;

}

if (playertouchsme) {

  toweapons weapon_Dagger;

}

if (weaponfired){

  hitobjects 0.5,this.x+this.apos[this.dir*2],

    this.y+this.apos[this.dir*2+1];

  freezeplayer .4;

  setani sword,wbow1.png;

}
