I was creating a solution for a custom level I created, I received this error tmp13[tmp14] is not a function on `posChange = Vector.substract(friend.pos,nearest.pos);`

and I am unable to spot any errors in this function even though I experienced similar error before.

```
this.kite = function(friend){
var enemies = friend.findEnemies();
var nearest = friend.findNearest(enemies);
if(nearest){
var posChange = Vector.substract(friend.pos,nearest.pos);
//var posChange = Vector.substract(friendPos,enemyPos);
posChange = Vector.normalize(posChange);
posChange = Vector.multiply(posChange,10);
var finalPos = Vector.add(posChange,nearestPos);
if(friend.distanceTo(nearest)<10){
//this.command(friend, "move", {x:friend.pos.x+10,y:friend.pos.y
this.command(friend, "move", finalPos);
}else{
this.command(friend, "attack", nearest);
}
}
};
```

I also found out that the value of `friend.pos`

and `nearest.pos`

returns 3 axis, x,y,z. I tried making an extra variable without the z axis but the same error still happens.

```
friendPos = {x:friend.pos.x,y:friend.pos.y;
enemyPos = {x:nearest.pos.x,y:nearest.pos.y};
var posChange = Vector.substract(friendPos,enemyPos);
```

same error still applies ^^
