A problem with getangle

[Kyranki]

Currently scripting some custom projectiles however I'm having a problem with my getangle();

PHP Code:

/*

  ** Custom Projectile Notes **
: Attributes
  - Attr 1: Base Direction
  - Attr 2: Speed Calc
  - Attr 3: P-Type, (Random, Track)
  - Attr 4: Tracking Who/Owner, (String: Npc, Player)
  - Attr 5: (Npc/Player Id
  - Attr 6: Coords of mouse click
 
: Variables
  - Speed: How fast this projectile will travel
 
*/
function onCreated() {
  canwarp();
  canwarp2();
  
  setimg("block.png");
  setTimer(0.1);
}
function onTimeout() {
  if (this.attr[3] == "random") {
    echo("Projectile: Has a randomized movement pattern.");
  }
  else if (this.attr[3] == "track") {
    temp.obj = this.attr[4] == "npc" ? this.level.npcs[this.attr[5]] : this.level.players[this.attr[5]];
    if (temp.obj.objecttype() in {"TServerPlayer", "TServerNPC"}) {
      temp.tx = temp.obj.x;
      temp.ty = temp.obj.y;
    
      this.dir = getdir((temp.tx - this.x), (temp.ty - this.y));
      this.attr[1] = getangle((temp.tx - this.x), (temp.ty - this.y));
    }
  }
  this.chat = "Direction: " @ this.dir;
  if (onwall(this.x, this.y))
    destroy();
  for (temp.pl : this.level.players) {
  }
  for (temp.nc : this.level.npcs) {
  }
  this.x += cos(this.attr[1]);
  this.y += sin(this.attr[1]);
   
  setTimer(1);
}
function onPlayerChats() {
  if (player.account in serveroptions.staffdevaccess.tokenize(",")) {
    if (player.chat == ":destroy") {
      destroy();
    }
  }
} 


The major problem is where I use getangle to set this.attr[1]. It's getting the wrong angle tho that should work.

It's moving in an arc away from the player like this... _|
