Swipe up action

Hi Patrick, although you're right and this is not available via the drop down, it is possible to calculate this yourself :) See below: 

Hi Marek,

You're right! The first thing we need to do is to block usual swipe reaction:

global.touchSystem.touchBlocking = true;
global.touchSystem.enableTouchBlockingException("TouchTypeSwipe", true);

Then, we can calculate where our user is swiping by looking at their touch start and touch end position. For example in a script set on Initialized: 

var touchStartPos;

var event = script.createEvent("TouchStartEvent");
event.bind(function(eventData){
 touchStartPos = eventData.getTouchPosition();
});

var event = script.createEvent("TouchEndEvent"); 
event.bind(function(eventData){
 if (touchStartPos) {
   var currentPos = eventData.getTouchPosition();
   var posChange = new vec2(currentPos.x - touchStartPos.x, currentPos.y - touchStartPos.y);
 
   if (posChange.y > 0) {
     print("Swiped Down");
   } else {
     print("Swiped Up");
   }

   if (posChange.x > 0) {
     print("Swiped Right");
   } else {
     print("Swiped Left");
   }
 }
});

Let us know what you end up creating :)
