<s>[INST] This is the fifth level of the Ruby Warrior project. The floor is 11 spaces wide and 4 spaces long. The warrior is at position (4, 0), and there is a wall at position (3, 0) so he can't move left. The warrior is facing right. 

Here's the current state of the floor:

```
  X | . | . | . | W | . | . | . | . | . | . 
  ---------
  . | . | . | . | . | . | . | . | . | . | . 
  ---------
  . | . | . | . | . | . | . | . | . | . | . 
  ---------
  . | . | . | . | . | . | . | . | . | . | . 
```

You have the following code to begin with:

```ruby
class Player
  def play_turn(warrior)
    # Your code goes here
  end
end
```

Write the move the warrior to the right. If there is a wall or an enemy to the right of the warrior, he should attack instead of moving. 

```ruby
class Player
  def play_turn(warrior)
    if warrior.feel.empty?[/INST]
