Problem with touch controls

Hey Godot Forum!
I am making a simple mobile game and I am now on the point where I am implementing touch controls into my game.
I want it to go up when I tap the screen and to the side when I swipe left or right ( and down if I swipe down ).
However whenever I try to put in the tap control it will override the swipe controls everytime. I believe this is because that when I first touch the screen, it registers as a tap and doesn't care if I swipe the screen after that. If anyone has any solutions to fix this problem that would be much appreciated! Anyway, code is down below! ( tap code is commented out )

extends Node2D

func _input(event):
	var is_drag = event is InputEventScreenDrag
	var is_press = !is_drag and event.is_pressed()
	var is_release = !is_drag and !event.is_pressed()

	if is_drag:
		if $TouchScreenClass.get_drag_direction(event.relative, 25) == Vector2.DOWN:
			print("down")
			$TouchScreenClass._on_self_released()
		if $TouchScreenClass.get_drag_direction(event.relative, 25) == Vector2.UP:
			print("up")
			$TouchScreenClass._on_self_released()
		if $TouchScreenClass.get_drag_direction(event.relative, 25) == Vector2.LEFT:
			print("left")
			$TouchScreenClass._on_self_released()
		if $TouchScreenClass.get_drag_direction(event.relative, 25) == Vector2.RIGHT:
			print("right")
			$TouchScreenClass._on_self_released()
			
#	if event is InputEventScreenTouch:
