Help in Hit Points challenge!

I have tried solving it in this way with no success... I know there is an easier way but I want to complete it this way... Please help :(

# move((1, 1, 10), (-1, 0)) => (0, 1, 10)
# move((0, 1, 10), (-1, 0)) => (0, 1, 5)
# move((0, 9, 5), (0, 1)) => (0, 9, 0)

def move(player, direction):
    x, y, hp = player
    x_move, y_move = direction
    nx = x + x_move
    ny = y + y_move

    if (nx) in range(0, 9):
        x = nx
    elif nx > 9:
        hp -= 5
        x = 9
        x = 0

    if (ny) in range(0, 9):
        y = ny
    elif ny > 9
        hp -= 5
        y = 9
        y = 0

    return x, y, hp

Hi Daniel Adari. Actually, you are closer than you may think :smile: , your approach it's good and it works just fine, double check the second elif statement, something it's missing from the end. Happy coding.

Good spot, too!! :smile: :+1:

Hi Daniel,

I had another look at this one to remind myself how this challenge worked.

I did the same as you and created two more variables to represent the x and y change. I then tested whether x plus the change in x position was either less than zero or greater than 9. If so, do nothing to x but take 5 off hp otherwise, allow the change in the else part of the conditional test. Then do the same with y.

I hope that makes sense.


Hi Daniel,

You need to test for scenarios where x or y may become less than zero; not just greater than 9.

I hope that helps a little! Else, get back to me and I'll explain further ... post any new code, though.
