public class ReflexAgent

extends AbstractGridWorldAgent

Below is a very basic agent that will traverse poorly through the Wumpus World. This is similar to the gridworld agent, but there are few new things that adhere to the Wumpus game rules. If you fall in a pit you die, if you go to the location as a live Wumpus, you die. You have one arrow to use, you use the getEnvironmentInfo().getCurrentNode().getPercepts() to view the percepts of the current node which can be a BREEZE, STENCH, SCREAM, BUMP, or GLITTER. You can get the current direction by the use of the hints class. You set the new agent move by setting the direction that you want to go. These can be found in the WumpusConstants class. North is up. If the you move bumps you into a wall a "BUMP" percept will appear in the following EnvironmentInfo. The agent must set the previous current node to the current node, otherwise you will be inside the wall.

The agent can pickup gold using the pickUpGold() method in the Move class. If the current node has gold in it the gold will disappear and isGoldPickedUp() method in the EnvironmentInfo class will return true, else it will return false. The Wumpus Environment will compare the current node sent in the Move class with it's own internal current node. If these do not match the gold will not be picked up.

The agent can shoot an arrow in a direction once. The method shootArrow() is used for this. It takes a direction as an argument. The Wumpus Environement the traverses the direction that the arrow was shoot. If the arrow hits the wumpus a "SCREAM" is provided in the following percept list. If the arrow hits a wall nothing is returned. Once the arrow is shot you can not shot another. The isArrowShot() and isWumpusDead methods in the EnvironmentInfo class will provide info about the current status of the arrow and wumpus. If the Wumpus is dead agent can move to the Wumpus's location and not die, the stench will still be around it.

This agent simply randomly chooses a direction to go using the randomDirection() method. After four moves, if the agent has not died, it will shoot an arrow in the South direction. The agent keeps moving until it is dead or gets the gold and returns to the start location. I have not ever seen it do this. It sometimes will shoot the wumpus and pick up the gold but it always hits a pit.
