New code (pointing to a missing class): shoot and Arrows

Some detail has been added to the Player.shoot method compared to the pseudocode. First, inside the Player class we have the method,

    def shoot(self):
        roomlist = input('What rooms [a, b, c]? ')
        self.arrows = self.arrows - 1
        print 'Shooting...'
        # Uncomment the next line when you are ready to add the code it requires.
        # The return below it is a temporary statement to allow the program
        # to execute.
        # return Arrow(self.location, roomlist).fly()
        return MISS

The shoot method will get the list of rooms for the arrow to fly through from the user, decrement the number of arrows left by 1 and then create an Arrow object and tell it to fly. Note that the line Arrow(self.location, roomlist).fly() does two things. It first creates an Arrow object with Arrow(self.location, roomlist) and then it immediately sends it the message to fly with the appended .fly(). This line is commented out at the moment since it would just throw an error because there is no class Arrow (you will be creating it as part of the assignment). To make the code runnable I have simply added an artificial return statement that returns a legal value of MISS.

MISS is one of three values that the fly method can return; the other two are HIT and OOPS. These three values correspond to the three possible outcomes of shooting an arrow: you could hit the wumpus (HIT), miss the wumpus (MISS), or shoot yourself (OOPS). Shooting yourself can happen either if you include your current room in your flight path (not too likely) or if you include unconnected rooms in your flight path. In the latter case the arrow will begin to fly randomly and may come back at you and hit you.

The constants are assigned by the statement,

(HIT, OOPS, MISS) = range(3) # Possible outcomes of shooting an arrow.

The section of the main routine handling shooting was expanded to deal with each possible return value appropriately,

    elif action == 's':
        outcome = player.shoot()
        
        if outcome == HIT:
            print 'You hit the wumpus! You win!'
            game_over = True
            
        elif outcome == OOPS:
            print 'Ouch! You shot yourself!'
            game_over = True
            
        elif outcome == MISS:
            print 'I\'m afraid the Wumpus wasn\'t in any of those rooms.'
            print 'You wasted your arrow.'
