UMG widgets stops tilt input on mobile

Development Programming & Scripting
1

UE4 4.5.1 on Mac OS Yosemite.
Can anyone please help.
I’m about to submit a game for iOS but this bug is stopping me. Touching any UMG widget (button, text or image) stops Tilt (accelerometer) input and returns 0,0,0 touching screen where there is no widget reactivates Tilt.
Thanks

I’ve posted a video of bug here - YouTube

if i enable virtual joysticks in project settings touch input it sort of works.
but i have to touch one of joysticks to enable tilt input after this game works fine until i close app and reopen it and again have to touch joysticks. video posted here - YouTube
if anyone can help with a touch interface workaround or fix ASAP I and others with this issue would very much appreciate it

Hello ,

I watched your video and see what you are talking about. It does appear that tilt is temporarily disabled or set to inactive when using touch inputs. Would you mind providing device specifications you are testing your game with?

Also is this a code project or a blueprint based project?

Thanks,

hi andy,
thanks for your response. All built in BluePrint tested on both iPhone 5 and iPad 2 both running iOS 8 i also see someone has same issue with Android here Touching UMG stops Tilt output. Any fix? - Mobile - Epic Developer Community Forums fault is with UMG widgets even touching target recital (image) and score (text) stops accelerometer. as you can see in second video enabling joystick touch interface almost fixes it but i have to move a joystick to enable accelerometer. any help is much appreciated. let me know if you need anymore info, Thanks again

hi again, I’ve just taken time to update to 4.6 and converted my project and can confirm that i still have exactly same issue.

In fact i’d say joysticks doesn’t help; it’s entirely if you touch anywhere on screen that is not UMG widgets accelerometer will begin to work. For me users have to tap screens ‘start game’ button to begin game, but they have to tap screen again to get movement (tilt based) controls to work. As you can imagine, this is fairly game breaking. Any fix would be severely appreciated.

Hey guys,

I am assigned to both of your posts about this issue and am going to merge them since they seem to be same.

Would you provide me with some basic steps to reproduce in order for me to play a test game with a widget and tilt so I can test it on my end?

If you are comfortable with it, you can send enough of your project over for me to test as well.

Thanks,

Andrew

Cheers Andrew,
I’ve built a new simple project just for you my friend, using tilt input to control a ball and made a hud widget with buttons which is created and added to viewport in level BP I’ve tested it on an iPhone 5 with same problem how do i send you project?

Awesome, thank you for doing so. Content, Config, and Uproject files into a folder, and you can post in here on AnswerHub.

It was brought to my attention that this issue is known and has already been reported as a bug. It can be tracked in JIRA under number UE-5495. I apologize for not letting you know ahead of time, but it was just made aware to me that it is a known issue.

Either way developers are working hard to have this issue resolved and you can track its progress to see when it becomes fixed.

Thanks,

Thanks Andrew, file is 10.2Mb and exceeds 5.2 upload limit, do you still need it? what and where is JIRA?do we have any sort of time scale? would it be possible to create a temporary workaround or fix using touch interface in some way? sorry for so many questions but please understand my concerns as this will be my first game and for obvious reasons I’m desperate to submit to App store before christmas holidays.
thanks

I can confirm this on android, too. When starting a level you first need to touch screen to activate motion input.

Hey ,

Since this issue has been made aware to our development team I don’t need your project any longer, but if you still wish me to test it I can. I only needed it to confirm on my end that I could reproduce bug.

As for a temporary work around, I am unsure because it seems you really need your UMG HUD assets, but it also seems these same assets are what is directly affecting your tilt function. Maybe temporarily disabling your tilt and using joysticks in its place for navigation. That way you can keep your widgets and play game somewhat?

JIRA is our bug report manager and number should allow you to search for bug I provided and track its progress toward being resolved. I do understand your time constraints, but unfortunately have no control over when things will be fixed, which in turn means I have no set time frame when this will be resolved.

Keep in my our developers are always working hard to make sure major bugs and issues are resolved as quickly and efficiently as possible. With that in mind we ask our users to be patient with these issue because they aren’t always easiest to fix.

Thank you for your report and for your patience!

hi Andy,
if you please id rather this question was not marked as resolved as it reduces chance of anybody in community helping with a possible workaround. also i have searched and can’t find JIRA or any reference to bug reports.
thanks

here is a small test project, once tested on a device if you touch any widget tilt returns 0,0,0 if you touch screen anywhere other than a widget tilt input resumes if anyone can help with this bug it would be much appreciated

Hi Andrew,

  1. I’d like to comment that this is not only a UMG problem. If developers are only looking at UMG, they may not be finding root cause of problem. I get Tilt disruption when I have no UMG widgets created on my Level.
  2. How do you get to JIRA to follow progress?

I agree with above comment…fix for this would be seriously appreciated.

Thanks!
Byron
