On released event bug

Hello Simfo,

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 elaborate further on the issue that you are experiencing and as to how it is at an inverse to the result that you are expecting?
  2. Can you reproduce this issue in a clean project?
  3. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  4. Could you provide screen shots of any settings/blueprints/widgets that may be involved with this issue?

Button event “on released” is triggered in a second, but not after the button is released.

Hello Rudy Q,
“On released” event is triggered in about 0.5-1 second regardless of whether the button was released or not. Here is my clear bp prodject showing a bug. Just press the button and hold around 3 sec.[link text][1]

I’m sorry, I mean the event is triggered even if the button has not been released.

Thank you! But “Use Mouse for Touch” is the default setting if you create a project for mobile devices. And I can not test my game for mobile without it! In versions before 4.17, everything works fine with “Use Mouse for Touch”. In any case, such behavior looks strange.

On mobile devices “on released” events always works wrong. Setting “Mouse for touch” does not affect this in any way. For this reason, I cannot use 4.17 in production. Please, fix it!

The bug is still there. UE 4.18 preview 1.

Hello Simfo,

After further testing I was able to find further inconsistency and I have written up a report. I have provided a link to the public tracker. Please feel free to use the link provided for future updates.

Make it a great day

After taking a look at the project provided I found that this issue is cause by setting “Use Mouse for Touch” to true in your project settings. Disabling this will setting will prevent the release from firing for the mouse button is released. I hope that this information helps.

Make it a great day

Thank you!

I’ve also come across this bug and it does indeed happen on Mobile and PC.

Tested in 4.18.3

I have noticed this on 4.17 too, still waiting for a solution for 4.18.3.

It’s been 6 months already… version 4.19… the bug is still here :frowning:

Still waiting… I just stopped my project only because this bug still exist =/

Is this bug ever going to be fixed?

For mobile: As a quick fix I’m now checking if the button is pressed or if it is hovered. Seems like it is released when it is hovered.

bug disappears if IsFocusable set to false.

bug still exists in 4.19

Thank you for this fix! Hopefully that works for mobile too!

Seems to work on mobile!
