Hi guys, so I am stuck on brewball. I have got the first part right, catching a potion, but I am stuck on getting back to Omarn and I get this `t.copy`

error:

Here is my code:

```
// Say anything within 10m of Omarn for him to throw a potion.
// Catch the potion by standing near it before it lands.
// DO NOT LET THE POTION LAND ON THE GROUND!
while(true) {
var potion = hero.findFriendlyMissiles()[0];
var firetraps = hero.findNearest(hero.findHazards());
// Remember that a Fire Trap will trigger if you move closer than 3 meters!
var omarn = hero.findByType("potion-master")[0];
if(potion) {
var dest = potion.targetPos;
// Go get the potion.
var potion = Vector.subtract(dest, hero.pos);
potion = Vector.normalize(potion);
potion = Vector.multiply(potion, 5);
if (firetraps) {
if (hero.distanceTo(firetraps) < 3) {
var trapVector = Vector.subtract(hero.pos, firetraps.pos);
trapVector = Vector.normalize(trapVector);
trapVector = Vector.multiply(trapVector, 10);
potion = Vector.add(trapVector, potion);
}
}
// Warning: isPathClear doesn't work with Hazards!
var moveToPos = Vector.add(hero.pos, potion);
hero.move(moveToPos);
} else {
if(omarn && hero.distanceTo(omarn) > 10) {
// Move back to Omarn.
var home = {"x": 14, "y": 34};
// Go back to the x.
var xpos = Vector.subtract(home, hero.pos);
xpos = Vector.normalize(xpos);
xpos = Vector.multiply(xpos, 5);
if (firetraps) {
if (hero.distanceTo(firetraps) <= 3) {
trapVector = Vector.subtract(hero.pos, firetraps.pos);
trapVector = Vector.normalize(trapVector);
trapVector = Vector.multiply(trapVector, 5);
xpos = Vector.add(trapVector, xpos);
}
}
// Warning: isPathClear doesn't work with Hazards!
moveToPos = Vector.add(hero.pos, xpos);
hero.move(moveToPos);
} else {
hero.say("Hup, hup!");
}
}
}
```

Thanks for any help!
