GestureState.Failed happening "randomly" during TransformGestures about gestouch HOT 11 CLOSED

First of all let's ensure we're talking about the same version, so go and grab the sources from this commit
4398712

from gestouch.

Thanks for the quick reply!

I switched from the swc to the latest src, and then merged in your two changes from 4398712.

Sadly, I still see fail states. Here is how I'm detecting them:

    public function onSCMouseMove(event:GestureEvent):void {
        trace("[SceneStage] onSCMouseMove:", event.oldState + "->" + event.newState);
        if (event.oldState == GestureState.FAILED)
        {
            trace("[SceneStage] onSCMouseMove() - Gesture state: FAIL");  
        }

Some output:

[SceneStage] onSCMouseMove: GestureState.CHANGED->GestureState.CHANGED
[SceneStage] onSCMouseMove: GestureState.CHANGED->GestureState.ENDED
[SceneStage] onSCMouseMove: GestureState.ENDED->GestureState.IDLE
[SceneStage] onSCMouseMove: GestureState.IDLE->GestureState.POSSIBLE

from gestouch.

Check the project settings again because there's no more IDLE anymore.
https://github.com/fljot/Gestouch/blob/4398712f0c5b704818457bf120193157bd09dfdb/src/org/gestouch/core/GestureState.as

from gestouch.

So, with the recent version, show me the stacktrace once it fails:

if (event.newState == GestureState.FAILED)
{
    trace("failed:", (new Error()).getStackTrace());
}

and did I get you right — it fails while you're moving?

from gestouch.

Found the "develop" branch and I'm now using that -- master still has idle for me for some reason.

Also found that I needed to convert to GESTURE_RECOGNIZED in a few cases where I was using something else. Seems like you cleaned some things up, and I wasn't getting a location coordinate for the event state I was previously using.

Onward:
Here is the behavior I'm using to repro:

click -> release // (to select an object to transform)
clickhold ->drag ->release // moves an object
clickhold ->drag ->release // move here
clickhold ->drag ->release // move there
clickhold ->drag ->release // move somewhere else
clickhold ->drag // FAIL

The fail happens before the move -- the object stays put / the cursor moves without it.

Here's the latest trace with your code:

While still seemingly random, the fail state happens quite easily in my case. I'd be happy to skype-screen-share with you to show you first hand if that helps.

Thanks for your support. :)

from gestouch.

Well the log says that:

1. First you stop TransformGesture (dragging) via releasing the touch.
2. Then you attempt to do it (pan/transform) again, but another gesture (Swipe) is recognized therefore your TransformGesture fails.

my skype is fljot_

from gestouch.

Ugh - good call. I had a swipe gesture in there from an old test that was interfering. Thanks so much for helping to troubleshoot that.

Question - should I go back to the gestouch swc I was using, or do you think it's best to stay with the dev branch?

from gestouch.

I'd say this commit from develop branch has nothing experimental and I should actually make a release out of it or maybe a bit later.. so I'd say go with it.

But for me it's still a bit unclear how would swipe be recognized first.. only if it was deeper than transform?

from gestouch.

Yes - swipe was initialized after the transform was initialized. Is it more standard to do it before?

I think I'm having a similar issue with double-tap -- the transform is listened to first, so it makes it more difficult to successfully make a double-tap happen.

Thanks again for your support here.

from gestouch.

Transform and double-tap should not conflict due to different nature — you don't move your finger (much) when tapping. Well you have my skype.. because it sounds a bit weird what you say)

from gestouch.

It's pretty sensitive on my ipad3 -- difficult to get my double-tap context menu to show without moving the object via the Transform Gesture. I was thinking about doing some "this cancels that" logic, but I'm not at that point yet. I added you on skype -- would be happy to show you the repro :)
