couldn't find 'move'

Hi there,

What is move_made? Where is it defined?

Also, your moves are strings. The direction variable contains a tuple that is an x, y coordinate change of the move; the example given in the question is, a direction tuple that's two parts, the x to move and the y (like (-1, 0) would move to the left but not up or down). We can't assume only a single-unit move can be made at once, though, but all the examples suggest such. The move is a numeric change of coordinate, not a string representation.

You need to start by determining the x & y position of the player - that's given as a parameter in a three-part tuple which has been processed into three variables for you. Then add in the move from the direction tuple. Lastly, if either x or y is less than 0 or more than 9, modify the hp of the player from the three-part tuple. Also, reset the value back to zero or 9, depending which bound the player broke - that way, the player isn't left beyond the wall.

I'm no Python programmer at all so this is an ugly solution, but it works merely by way of illustrating the above explanation. I am sure there is a far more elegant solution which you should try to find!

def move(player, direction):
    x, y, hp = player
    dx, dy = direction  # determine the change of x & y
    x = x + dx    # apply the changes
    y = y + dy
    if x < 0:       # if it went beyond the wall
        x = 0       # reset its position
        hp -= 5    # reduce hp
    if x > 9:      # repeat for each wall
        x = 9
        hp -= 5
    if y < 0:
        y = 0
        hp -= 5    
    if y > 9:
        y = 9
        hp -= 5
    return x, y, hp

Make sense?

Steve.
