No single touch event is fired when multitouch is activated

Hi,

when multitouch is activated, no singletouch event is fired. And a single touch then pulls the framerate down to sometimes half a frame per second. I would say that this is not really practical or?

Also event.touches contains always just one touch. Is this by design? I thought that event.touches hold everything that is current and event.previoustouches from the last event.

The issue still exists Tom.

Take your left index finger and press down. Now hold it really really still so no events are being generated.

Then place your right index finger on the screen. No event is generated. That’s what this is talking about.

Scott,

When I do that I see the following: ctouches: 1, ptouches: false -> ptouches: 1. If I add another finger, ptouches: 2.

If I hold my index finger on the screen and press and remove my right index finger the ptouches field goes from false -> 1 -> false. ctouches stays at 1 the entire time.

I do see a problem if I touch my left index finger; touch my right index finger; and remove my left index finger. In this case ctouches: 1 and ptouches: 1 at the end. I’m not sure if this is the correct response since I’m not looking at the previousTouch events.

If I touch my left index finger; touch my right index finger and remove my right index finger I get ctouches: 1 and ptouches: false (which is what I expected).

I’m not sure all the responses are correct but I do see events for multiple touches. It seems like there is a lack of events (sometimes) when fingers are removed but not when fingers touch the screen.
