Question by unity_dXpy2EIPXZSeaQ · Apr 19, 2019 at 10:01 AM · unity 5 ui trigger touch click

UI buttons sometimes does not detect touch

When I touch a button on my mobile device, sometimes the click function is called, sometimes it's not. When I click the button with a mouse on my PC, the click function is always called fine (the problem only exists with the touch).

The function is called through the EventTrigger:

  EventTrigger trigger = GetComponent<EventTrigger>();
  EventTrigger.Entry entry = new EventTrigger.Entry();
  entry.eventID = EventTriggerType.PointerClick;
  entry.callback.AddListener((data) => { OnPointerClickDelegate((PointerEventData)data); });
  trigger.triggers.Add(entry);

I have both Standalone Input and Touch Input modules enabled in Event System. I tried different solutions posted online and nothing worked for me.

Any idea?

Thanks!
