What is wrong with this code

help me out here

movement.py 
# EXAMPLES:
# 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
    xd, yd = direction

    if xd + x >= 9:
        hp -= 5
    else:
        x += xd
    if xd - x <= 0:
        hp -= 5
    else:
        x -= xd

    if yd - y <= 0:
        hp -= 5
    else:
        y -= yd
    if yd + y >= 9:
        hp -= 5
    else:
        y += yd
    return x, y, hp

You are headed in the right direction, but have some issues:

"...if the player is being run into a wall, their hp is reduced by 5. Don't let them go past the wall."

:point_right: if the position would be greater than 9 or less than 0, set the value to the max 9 or min 0 instead.

:point_right: You are using <= 0 and >= 9 when it should be just '< 0' and '> 9'.

The x += xd statements may be executed twice for positions not near the borders. Same for y += xd.

:point_right: The two if statements for x and for y checking should use if... elif... else format.

The position change may be positive or negative relative value

:point_right: always use plus to add the new direction to the current position. You are mixing pluses and minuses.

Post back if you need more help. Good luck!!
