touch screen object problem? becomes unresponsive after scrolling

Kazuya · November 11, 2015 at 9:22 AM

Hi, I'm making a pinball game for touch screen devices (currently testing on windows tablet) using the touch screen object.

The game works perfectly (flippers, nudges are all instant and responsive)
however, when the screen moves to another area (bonus table) the "touch" becomes laggy and sometimes doesn't respond at all.

The touch is detected on large (invisible) actives which go over the flippers and nudge areas.
Those objects move to the correct areas when the screen scrolls, so that isn't the issue.

I get the same problem with a separate game I'm making (which is an online fighting game) as soon as the screen starts scrolling the "touch" stops responding properly.

I notice the touch object doesn't have "follow frame" as an option (?)

Do you mean the Multiple Touch object?

Also, if you could post an example file with the issue it would be very helpful:)

I had the same thing.
I had a scroll bar that I wanted to use to touch and then drag to scroll the BG. It fet like because the BG was moving but the scroll bar wasn't the last touch x,y was getting confused. I'm getting around it by not using the scroll function on the BG.

Yes, the "multiple touch" object by francois. Is there an alternative that works with scrolling?
Thanks

the multi touch object does work with scrolling.. you need to post an example of your broken code so someone can help

Please login to see this link.

I stripped out all other code - it simply has the "touch". The flippers work perfectly until you tap the arrow to go to 2nd table (or push right cursor)
once on the second table the flippers are unresponsive and even the exit button fails.
If I click the left arrow (to return to first screen) the flippers are responsive again.
Same objects, same code on both screens.

Testing on Windows Tablet.

Just a simple horizontal scroll bar that scrolls the BG half way before getting confused:

Thanks.

good to know it's not my "broken code"

But I really need touch screen to work on scrolling apps (not just for pinball - I have lots of other stuff I want to convert to mobile/tablet!)

I wonder if Francois knows about this problem (he made the extension, right?)

Have you tried to put your MultiTouch object on layer with fixed position? (x and y coefficient set to 0)?

steakor · November 13, 2015 at 11:43 AM

Lazarus this sounds interesting could you elaborate on this or send us a little example? Thanks

steakor · November 13, 2015 at 2:19 PM

Currently I set:
Properties>Runtime Options> Follow the frame
To OFF for the multitouch object and the scroll bar objects so that they don't follow the scrolling, is there something more I should be doing with their Layer?

Kazuya · November 13, 2015 at 6:30 PM

I just tried Lazarus's suggestion and uploaded again to my site:

I put the multitouch object on another layer and set the coefficient to 0,0

Same issue though

steakor · November 13, 2015 at 11:11 PM

Same here:

I'm not sure it's the multi touch though, I changed all the settings in mine to mouse clicks instead and still got the crazy results, perhaps something to do with the scrolling more than anything?

ah, so yours is an android app? I was wondering if it was just a Windows only thing but it must be the object or some other issue in fusion

Kazuya · November 17, 2015 at 1:35 PM

so, does nobody have a solution for this ? Other than remaking our apps to be on only one screen? (I actually tried doing this yesterday but it was so much hassle, splitting each part that I gave up..)

I don't understand what the horizontal scroll example posted above is suppose to do.
What build of Fusion 2.5 are you guys using?

steakor · November 17, 2015 at 5:13 PM

Hi Jeff, basically it's a scroll bar at the bottom, that you can move left and right and have this scroll the background left and right whilst keeping the scroll bar where it is.
What seems to happen is you get half way and then the scrolling freaks out.

If anyone has an example of this working that would be really useful.

Kazuya · November 17, 2015 at 7:51 PM

Jeff please try my example uploaded above - and try it on an actual tablet or phone. It works fine within fusion or on a PC (mouse click simulating a "touch" ) but on actual touch screen strange things happen, after the screen scrolls -
and even the ability to close the app becomes laggy

284.10 build (dev)

Jeff · November 17, 2015 at 8:47 PM

Its the app named Horizontal Scroll right?
The top part isn't scrolling or moving for me at all.

Can't even see any events that would cause it to move so I don't know what I am missing here.

Does this file work if you build it?

I am using the next build of Fusion but I don't think there is any change in this area.

steakor · November 18, 2015 at 12:44 AM

Hi Jeff,
Yes I opened your .mfa, but when I tried to build the .apk it failed?
My Phone is on Android 4.4 if that changes things?

Strange that you couldn't see any events, maybe I uploaded the wrong one, try here:
