[4.11 - ISSUE] Touch Moved Isn't Working Properly

Development Programming & Scripting
1

Hey guys! Since I’ve updated my project to 4.11 there’s been an issue with my touch Input. Whenever I start the game in whatever mode, touchMove isn’t firing.

So, You’ve to click outside the viewport and then click again, and it works. It’s been really hampering my project.

I think it’s a bug as it was working perfectly before 4.11.

I’m going to test it on a mobile device and see what happens? Will update the post.

[UPDATE]

[TEST DEVICE] iPhone 6s and iPhone 6plus

[TEST RESULT] Its working well on iPhone 6plus. But on iPhone6s, it’s exactly the opposite. touchMove is working correctly, however touchStart or Pressed isn’t working on world objects. But, they do work with UMG touch events.

Thanks.

Hello ,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide screen shots of any blueprints that may be involved?
  4. If you delete you save, intermediate, and config files before updating, does the issue still occur?

Note: You may want to make copies of any files before deleting them.

I think it is the same issue and there are steps to reproduce it:

Hey, @

I’ve tested in a new project and everything works as expected. Maybe something went wrong while switching between the engine versions.

Here is a video demonstration of the problem I’m facing.

Hope it represents the problem correctly. Thanks.

@ Just updated my project to 4.11.2 in a hope that it might fix my issue as it covered a lot mouse detection problems.

But still the same…

Is there any solution so far???

Thanks

@ I was able to reproduce this issue in a new project create using 4.11.2

  1. Steps to reproduce the issue.
  2. Create a new blank mobile project
  3. Create a controller and add a touch event in it.
  4. Add Print String on touch pressed and touch moved
  5. Add your controller to the game mode
  6. Play the game in PIE mode
  7. The Rest is same as shown in the video.

But it works alright in mobile preview.

Please tell me that it is a bug and will be fixed soon.

Thanks

Hi Rudy,

This isn’t really about this topic but most of you staff guys suggesting deleting “saved, intermediate and config” files in order to solve some problems.

But deleting config file causing character not to work or move. For example if you open just a simple third person template project and after deleting config file and open back UE, default map changes and also Third Person character seems not moving at all, wasd buttons isn’t working.

Is there some easy way to solve this or deleting config file always cause this ?

For a quick fix: In your project settings under the Input tab set Default Viewport Mouse Capture Mode to No Capture and I also set the Default Viewport Mouse Lock Mode to Do Not Lock.

To visualize your cursor enable mouse cursor in the settings of your player controller. Now touch movement should work fine.

It was the solution for me.
Thanks!
