Knights and Archers

They are in front of us, behind us, and we are flanked on both sides by an enemy that outnumbers us. They can't get away from us now!

What if the board was larger and with more enemies? If your code is general enough, you shouldn't need to change much, and the lone explorer should be able to defeat all the enemies!

You can use the Space methods isKnight() and isArcher() to check if a Space contains a specific enemy.

API

Note: walk, getSpace, look and poke can each take in a direction parameter (either Direction.RIGHT or Direction.LEFT). If no Direction is passed in, they will default to Direction.RIGHT.

• walk() - Moves the explorer forward (to the right) one Space.
