An error in getting_started/first_2d_game/03.coding_the_player

# Description
In the Choosing animations section, there is the following code
```gdscript
if velocity.x != 0:
$AnimatedSprite2D.animation = "walk"
$AnimatedSprite2D.flip_v = false
# See the note below about boolean assignment.
$AnimatedSprite2D.flip_h = velocity.x < 0
elif velocity.y != 0:
$AnimatedSprite2D.animation = "up"
$AnimatedSprite2D.flip_v = velocity.y > 0
```
I think it does not fulfill the intended function
If you want to make a move down to the left or right, it doesn't flip up and down,
I think it needs to be changed to the following code to achieve the desired effect.
```gdscript
if velocity.x != 0:
$AnimatedSprite2D.animation = "walk"
elif velocity.y != 0:
$AnimatedSprite2D.animation = "up"
if velocity.x != 0 or velocity.y != 0:
$AnimatedSprite2D.flip_h = velocity.x < 0
$AnimatedSprite2D.flip_v = velocity.y > 0
```
