# Problem with jumping 2D physics

Attention Topic was automatically imported from the old Question2Answer platform.

Basically, whenever i am walking and i spam the jump button my player doesn’t fall back down, he just does more jumps.
Here is the jump physics script

``````func _physics_process(delta):
get_input()
velocity.y += gravity * delta
velocity = move_and_slide(velocity, Vector2.UP)
if is_on_floor():
if Input.is_action_pressed("jump"):
velocity.y = jump_speed
\$PlayerSprite.play("Jump")
``````

what is the `Vector2.UP` for?

try to use this code

`````` func _physics_process(delta):
get_input()
velocity.y += gravity * delta
if is_on_floor():
if Input.is_action_pressed("jump"):
velocity.y = jump_speed
\$PlayerSprite.play("Jump")
move_and_slide(velocity, Vector2.UP)
``````

Thanks so much for the answer, but this wasn’t the solution. But I did notice that under the code that made the player walk I added script which said:

``````	if Input.is_action_pressed("walk_right"):
\$PlayerSprite.play("Run2")
velocity.x += speed
**if Input.is_action_just_pressed("jump"):
velocity.y = jump_speed
\$PlayerSprite.play("Jump")**
``````

and

``````elif Input.is_action_pressed("walk_left"):
\$PlayerSprite.play("Run")
velocity.x -= speed
**if Input.is_action_just_pressed("jump"):
velocity.y = jump_speed
\$PlayerSprite.play("Jump")**
``````

all I needed to do was to delete the extra jump commands and it stopped. (The ** is to show which part I am talking about).
