Can't get past the dungeon game hit points challenge. Not sure what I'm getting wrong.

def move(player, direction): x, y, hp = player xd, yd = direction if x == 0 and xd -= 1: hp -= 5 xd = 0 if x == 9 and xd += 1: hp -= 5 xd = 9 if y == 0 and yd -= 1: hp -= 5 yd = 0 if y == 9 and yd += 1: hp -=5 yd = 9 return x, y, hp

# 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 x == 0 and xd -= 1:
        hp -= 5
        xd = 0
    if x == 9 and xd += 1:
        hp -= 5
        xd = 9
    if y == 0 and yd -= 1:
        hp -= 5
        yd = 0
    if y == 9 and yd += 1:
        hp -=5
        yd = 9
    return x, y, hp

if variable_name -= 1:

is not a valid conditional statement.

may be you meant.

if variable_name == -1:

If there is still a problem then...you probably are not considering all possible scenarios.

For example, in your first condition

if x == 0 and xd == -1:

Considers when the focus in on left border and xd(x_displacement) is towards left side(-1). Cant move, hit the wall and hitpoints reduce by 5. but what when the player in in center of the board and trying to move left.(when x>0)

Answer is: .

# 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 == -1:
        if x == 0:
            hp -= 5
            xd = 0
        else:
            x = x-1
    if xd == 1:
        if x == 9:
            hp -= 5
            xd = 9
        else:
            x = x+1
    if yd == -1:
        if y == 0:
            hp -= 5
            yd = 0
        else:
            y = y-1
    if yd == 1:
        if y == 9:
            hp -=5
            yd = 9
        else:
            y = y+1
    return x, y, hp
