Constructor. Initializes various percepts.

Method Detail

perceive

public void perceive(Environment env,
                     GridPoint gp,
                     int orientation,
                     java.util.Vector allAgents,
                     TransferPercept tp)

Used to set the percepts for each agent depending on their position and orientation in the grid. The Vector containing all the other agents is needed to calculate the natural language hints.

createWumpusImage

public void createWumpusImage(int imageX,
                              int imageY,
                              int wumpusFacing)

createAgentImage

public void createAgentImage(int imageX,
                             int imageY,
                             int agentFacing)

createGoldImage

public void createGoldImage(int imageX,
                            int imageY)
