Single touches don't seem to work on WebGL/iOS, but drags do

I have a simple cube with a box collider and a script with OnMouseUp/OnMouseDown which just toggles the box's color. It works fine on the desktop.

However, if I make a WebGL build and try it on iOS (in Safari or Chrome) I only see events if I drag my finger. A simple tap (down and up) doesn't register at all.

Is there something else I should be doing in this situation?

 

FWIW, I can see single touch begins and ends with Input.GetTouch(0). I guess I'll plumb them through myself.

 

at least on ipad iOS, had to disable Desktop browsing mode from (Settings/Safari/Desktop Browsing),
that helped for me (when touches were not registered normally).

 

Ah. Interesting idea! I gave that a go, but it didn't get the traditional OnMouseUp handlers working. Browser touch/mouse/pointer events are something of an undisciplined mess to begin with, so I guess I'm not surprised Unity is having trouble with it.

 

Hi, I'm having the same issue in my webGL build running on mobile browser. I have built objects with drag n drop functionality using mouse drag and new input system.
Trying this application on mobile browser, if I just tap the object i don't receive the mouse press cancel event; If I drag the finger I receive immediately the mouse press cancel event, and so I cannot interpret is as dragging.

Are there any ways to work with touch events in new input system for webGL running on mobile?

 

I'm slowly working my way through this paid solution.

I'm looking forward to innate Unity complete mobile support for WebGL on this front.

 

Hi, I have an update regarding this. Working with Press input of new input system with Touch as binding now the drag works as intended. The only issue that I'm having is that sometimes it still doesn't register the "Mouse Up" event if I don't move the mouse after I pressed it.

To recap briefly:
- the sequence Press - Move - Release is all handled correctly
- the sequence Press - Release is not handled correctly since the Release event isn't received
