In Ace of Coders, I tried to do this

```
 var friends = this.built;
 var soldiers = friends.findByType("soldier");

```

to separate my units. However, I get this error: tmp35[tmp36 is not a function]  
Any suggested fixes?

`this.built` is an array and does not have a `findByType` method. Your hero has the `findByType` method. The code should be:

```python
var soldiers = this.findByType('soldier', this.built);
// OR:
var soldiers = this.built.filter(function(unit) { return unit.type === 'soldier'; });

```

However, note that `this.built` includes dead units. If you want only the alive ones you can use:

```python
var soldiers = this.findByType('soldier', this.findFriends());
// OR:
var soldiers = this.built.filter(function(unit) {
    return unit.type === 'soldier' && unit.health > 0;
});

```
