Whenever I try to do a level in Desert, I always get "Pass an Array of units to findNearest"  
any help? I can’t finish any of the levels  
I’m not sure if this is a bug or if I just don’t know how to do an array

</div>

this.findEnemies() and this.findItems() and this.findFriends() all return an array. what are you trying to find the nearest of?

probably enemies. so

```python
var enemy = this.findNearest(this.findEnemies());

```

Will get you the nearest enemy

Or in two steps :

```
var enemies = this.findEnemies();
var enemy = this.findNearest(enemies);

```

Here, enemies is the array of all the visible enemies.

The proposed codesnippets should work. Maybe post the code handling exactly this so we can review it?

looks like you are mixing python and javascript. you need to get rid of the semicolon after the var enemy line

Sorry, I’m using only javascript, so I give my example in this language.

Oh sorry I didn’t clarify before, I’m using python  
and @sotonin, i tried to do what you said, I got rid of the semicolon, but it still doesn’t seem to work?

python doesnt use this. change this to self.

```python
self.findNearest(self.findEnemies())

```

var is used in JavaScript and a few other languages to declare a new variable. In python variables are declared implicitly so you should write `foo = ...` instead of `var foo = ...`.
