var screenSize

func _process(delta):

		get_node("rightplayer").position.y += -PLAYERSPEED * delta
	if(get_node("rightplayer").position.y < 382 and Input.is_action_pressed("ui_down")):

	if(get_node("leftplayer").position.y > 18 and Input.is_action_pressed("left_up")):

	if(get_node("leftplayer").position.y < 382 and Input.is_action_pressed("left_down")):
		get_node("leftplayer").position.y += PLAYERSPEED * delta
	
get_node("Ball") += ballDirection * ballspeed * delta

Hi Friends I am using Godot 3. There’s a mistake here.

get_node("Ball") += ballDirection * ballspeed * delta

help me

That line doesn’t make sense. get_node("Ball") retrieves a reference to the “Ball” node, and then you’re trying to add to it with +=

You probably want

get_node("Ball").position += ballDirection * ballspeed * delta

Thank you. Working successfully
