I would like to learn how to make mobile games. The game I'm working on is using swipe detection. After watching some tutorials I put together this code:

var swipe_start = null
var minimum_drag = 100

func _unhandled_input(event):
if event.is_action_pressed("click"):
    swipe_start = event.get_position()
if event.is_action_released("click"):

func _calculate_swipe(swipe_end):
  if swipe_start == null: 
  var swipe = swipe_end - swipe_start
  if abs(swipe.x) > minimum_drag:
    if swipe.x > 0:

This code should determine if the user swiped and in which direction (left or right). Also, in the Input Map I chose "click" to be left mouse click.

The game works when I'm playing on my laptop (I click and drag with mouse) so I published it on google play but when you play the game on phone the swipe detector doesn't work.

Any ideas

Try setting emualte mouse(or something like that) in the project settings.

beside, you can use _input(event) function and InputEventScreenTouch + InputEventScreenDrag to get swipes for your game(i used it and got some touch joysticks working and some nice things in my android game)
