"Is touching" triggered on distant touches

I'm working on a project with three touch areas (TouchFail.capx or browse to the HTML5 export). I've stripped my example to two touch areas.

The player may adjust a parameter using the slider and get extra points by moving around in the second touch area. The <font face="Courier New, Courier, mono">SliderMarker</font> adjusts to where the finger current currently is located on the Slider.

+ Touch: Is touching <font face="Courier New, Courier, mono">Slider</font>? <font face="Courier New, Courier, mono">SliderMarker</font>, Set Y to Touch.Y

+ Touch: Is touching <font face="Courier New, Courier, mono">SecondTouchArea</font>?

During my testing, the <font face="Courier New, Courier, mono">SliderMarker</font> adjusts to where the finger is currently touching the <font face="Courier New, Courier, mono">Slider</font>. I can also touch the <font face="Courier New, Courier, mono">SecondTouchArea</font> without problems.

When I branch out to different devices and/or different browsers, I see a new problem. When I'm touching the <font face="Courier New, Courier, mono">SecondTouchArea</font>, it sometimes takes control of the <font face="Courier New, Courier, mono">SliderMarker</font>.

I can make a video if it'll be clearer, but here's the testing steps:

1) Touch the <font face="Courier New, Courier, mono">Slider</font> and move around. Watch the <font face="Courier New, Courier, mono">SliderMarker</font> move with the finger

2) Drag off the <font face="Courier New, Courier, mono">Slider</font> and watch the <font face="Courier New, Courier, mono">SliderMarker</font> stop.

3) Drag back onto the <font face="Courier New, Courier, mono">Slider</font> and watching the <font face="Courier New, Courier, mono">SliderMarker</font> move again.

4) Repeat steps (1) through (3), this time moving a second finger inside the <font face="Courier New, Courier, mono">SecondTouchArea</font>.

The bug occurs in step (4): the <font face="Courier New, Courier, mono">SliderMarker</font> moves up and down with the finger in the <font face="Courier New, Courier, mono">SecondTouchArea</font>, and stays that way until both fingers are removed from the screen. Often times, I cannot control the <font face="Courier New, Courier, mono">SliderMarker</font> any more and have to restart the application.

Am I using the Construct 2 language wrong and/or is there a better way to do this? Or is this an issue with, say, Chrome on Android?

I feel like I've got too much junk here... if anybody needs me to provide some more information, please let me know and I'll get it.

Hi again! I've simplified the problem and provided more direct observations of what I'm seeing.

Am I completely missing how the "Is touching" event is supposed to work? Is there a better way to accomplish what I want? I'd like to think this is a bug in Construct 2, but I'm still so new to this way of expressing my intentions that I'm worried that I've overlooked something simple.

Thanks!

Hmm... really strange)

I saw somewhere smth like this. There was ask about two fingers and decision was using layers.

I forgot how it was((

It was like this: is touching object -> object set position to mouse.y(1)

(1) - its a layer number.

I tried to use the Touch.YAt( Touch.Index ) and Touch.YForID( Touch.ID ). A very similar problem occurs: the blue <font face="Courier New, Courier, mono">SliderMarker</font> toggles between the Y values of the two touches.

In the past, I've tried to capture the Touch.ID of the finger that first touches the <font face="Courier New, Courier, mono">Slider</font>. The logic would then only allow a touch with that same Touch.ID to manipulate the <font face="Courier New, Courier, mono">SliderMarker</font>. Unfortunately, this did not work either.

Are there any other ideas?

I guess I'm going to give this one last bump before I write up a bug report. I'd really hate for this to be an obvious problem.

Thanks!

Have you tried adding another condition to your event, an "inverted" (right click the condition - Invert) "Is touching SecondArea..." ?

I completely removed the <font face="Courier New, Courier, mono">SecondTouchArea</font> and the problem still occurs:
