How do I make the player "wait" to be able to move until he touches the ground after doing his smash attack ? This is what I got so far but it does not work

[Grzybowy Gornisz]

if Input.is_action_just_pressed("jump"):
		if is_on_floor():
			velocity.y = jump_velocity
		elif not has_smashed:
			moving=false
			velocity.x=0
			velocity.y = -jump_velocity*2
			has_smashed=true

if moving==true:
	var direction = Input.get_axis("left", "right")
	if direction:
		velocity.x = direction * speed
	else:
		velocity.x = move_toward(velocity.x, 0, speed)
else:
	await is_on_floor() 
	moving=true
