Hello,
I have an actor with a limited number of primitives and a widget component:
What feels like 95% of the time, it will accept clicks as expected. However, sometimes it doesn’t register the click at all. Here are some bizarre observations:
clicking multiple times does nothing
rarely, waiting several seconds and then clicking works
occasionally clicking on the outer cube instead of the inner one with the dot (without waiting) works
frequently clicking on the display number / smaller lower-left cube (without waiting) works
always, clicking on a different instance of this actor has the other instance trigger its click
I have tried a few settings on the widget component, in case it was somehow blocking clicks:
Interaction> Receive hardware input is false
Interaction> Window focusable is false
Interaction> Window visibility is self hit test invisible
The widget itself is set to not hit testable (self & all children)
I’m running out of ideas as to what might be causing this. The camera is fixed in place and clicking works most of the time, so I don’t think it’s an offset issue. Is there a debug setting that will report which actor IS absorbing the clicks?
And while checking things while writing this, I just noticed an instance of an entirely different actor not responding to clicks, one which has always accepted them before (and doesn’t have a widget component).
Widget reflector doesn’t show any widgets as blocking the click or active/focused at any inappropriate time.
Line trace says I’m clicking on the correct thing.
When I set a “print” at the very start of actor on-clicked, it (of course) prints when the actor successfully receives the click, but does not print when click isn’t registering.
Given that widget reflector shows nothing blocking, and line trace says it’s clicking on the correct actor… I don’t know. Is there some process that can prevent clicks from being received? But when I click on another actor, it immediately receives and acts on the click…
Ugh. Okay, I don’t know why this didn’t show up in the first trace, but this is on me. Turns out there’s an invisible actor blocking clicks, but because it moves, it’s not always blocking the same thing, which explains the irregularity.
So I suppose all I need to do now is figure out how to make something that’s not visible also not block clicks.
