UI elements that have the Active property set to true are blocking mobile taps to the elements underneath them. Example: In AdoptMe! on mobile, when using the backpack buttons are difficult to press or cannot be pressed.
Expected behavior
On mobile UI elements like buttons should respond when tapped.
Would you be able to share a screenshot/screen recording of the issue please? If the Active property is set to true, mouse click events should not propagate to the 3D view below, but they should still propagate to overlapping GuiObjects.
It seems that tap events should indeed be sunk for Active=true GuiObjects, based on current behavior.
Also, do you know if this is a new regression and when you first noticed it?
That was a link to the same issue I wrote in our adopt-me channel on Discord. You can disregard.
We have since pushed a fix on our side (we disabled the Active property from the backpack icons). So we are not in urgent need of a fix any longer. Here is more information on the issue in case it’s helpful on your end:
If you opened Adopt Me on a mobile device and then open the backpack, the UI buttons had no response. Our engineer confirmed this new behavior was not from any changes on our side. It appears to be from an update Roblox pushed today. Those UI elements, such as the buttons in the backpack UI, have the Active property set to “true”.
So, before the Roblox update all UI worked fine. After the update, UI stopped working until we did a hotfix.
We did modify some touch input processing behavior today, and I just reverted the change. Please let me know if you encounter any other user input regressions!
Spray Paint! was temporarily unplayable for mobile players due to this issue. Not a huge deal, but just seconding that I was experiencing this issue too.
