Remove lines 3-10 and do `hero.move(items[1].pos)` not `hero.move(items[1])`

First, you are defining the `items` to a blank list which result your hero don’t do anything. Second, you only need 1 array for `items`, because gems are `items`. Third, `items` is an array, you cannot just move into an array’s positions.

Try this:

```python
while True:
    items = hero.findItems()
    if len(items) >= 2: # When there are 2 or more gems...
        item = items[1] # Remember the second thing for array is '1'

        #Collect the Gem! Use moveXY()
    else:
        #Move to the center mark!

```

.  
**ITERATING AN ARRAY**  
An array is basically a list that stores things, where you need a “index” to iterate (also called loop) through it.  
The number inside a square bracket is called a “index”, where it helps you iterate through an array, for example:

```python
while True:
    enemies = hero.findEnemies()
    index = 0 # The index always start at 0
    while index < len(enemies): # While the index is less than the array enemies
        enemy = enemies[index] # Define the 'index' element enemies to 'enemy'
        while enemy.health > 0: # The reason to do this is to keep focus on this target, if you do not check the health, the hero will attack every enemy in the array only ONCE
            hero.attack(enemy)
        index += 1 # Add index by 1, so you can kill the next enemy
    # When there are no enemies, the while loop will finish and reset the index to 0 and find a new array of enemies if there are.

```

Your explanation is kind of incorrect, move only move 1 step, so he will only move once then go back to center again. Which will get him stuck

No, because it checks if there is an item, and if there ISN’T then it moves back

Still doesn’t work I think it might be a bug because I’ve tried everything and it keeps pulling up that message.

</div>

```python
while True:
    items = hero.findItems()
    if len(items) >= 2: # When there are 2 or more gems...
        item = items[1] # Remember the second thing for array is '1'

        #hero.moveXY(item.pos.x, item.pos.y)
    else:
        #Move to the center mark!

```

Do moveXY(pos.x, pos.y) like in the sample code.
