Title: Conflicting touch events causing crash?[SOLVED]
Post by: Clockwork Wolf on June 06, 2013, 11:49:20 PM

Hello all!
I'm encountering an odd crash in Unity, and I'm wondering if it's because I'm not using the touch events correctly?

I have a cube parented to the mainCamera, which has a fsm using touch object. Upon detecting a touch on the cube, I move to another state which rotates a cube in the scene. It returns to the wait state upon touch end, else it continuously rotates the cube.

The also exists a gameObject with an FSM that I am using to detect finger drags along the screen with Touch Event, and then moves to a state that drives the rotation of a null. With the later FSM engaged, it tends to crash Unity on the phone or tablet (Nexus 4, Kindle Fire HD)

I can't seem to figure out why - is this because the events are overlapping?

Please find attached a bare bones unity file, hopefully the playmaker FSMs come through properly.

I've also got an unlisted youtube video (http://youtu.be/8yweM88WgpQ) demonstrating this crash. Thanks for any pointers!

Hi,

 ok few things:

-- don't check "normalize" on the action "get touch info", this will give you an output ranging from 0 to 1 ( 1 being the width or height of the screen).

-- don't use the delta time of the "get touch info" since you have ticked "Per seconds" in the "rotate" action ( so get rid also of the float divide"

once you do that, everything is much better and dragging works as expected.

bye,

 Jean

Hi Jean!
I tried your suggestions and they worked perfectly! Thank you so much.

I think I understand why we do not need to use the change in time when using the seconds checkbox, but why would the things I'd originally done cause the crash?

It's not a divide by zero or floating point precision thing, is it?

Hi,

 Yes, it was actually, simply because you where doing the wrong set of procedures.

did you got it working?

Hi Jean,
Yes it is all working, thanks alot for your help. I wish I had unity pro, the debug over usb may be helpful in this case. Thanks again!
