Movement.py

Hi, there.

Could anybody clarify why my code doesn't work but it works in shell.

Thank you

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

if x == 0:
hp -= 5
if x == -1:
hp -= 10
if y == 0:
hp -= 5
if y == -1:
hp == 10

return x, y, hp
```

You're not accounting for the direction the player is trying to travel. Just because the player is at `x=0` doesn't mean they lose 5 HP. They'd only lose that if they were trying to travel to `x=-1`. Same for other cases where they're trying to leave the map.

Hi there,

This is my solution that worked:

```def move(player, direction):
x, y, hp = player
xd, yd = direction
if x+xd < 0 or x+xd > 9:
hp -= 5
pass
else:
x += xd
if y+yd < 0 or y+yd > 9:
hp -= 5
pass
else:
y += yd
return x, y, hp
```

I know it's been a long time since your post. Can you explain why are you using "pass" in your conditions?
