Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

ComboBoxString doesn't work with WidgetInteraction Component in packaged game


I'm trying to package my game for a release tomorrow but my ComboBoxString in the main ui doesn't receive any actions performed by my ViveController which has a WidgetInteraction Component attached. All other UI elements work fine, the ComboBoxString, however, doesn't show its drop down menu when I press it. When I try it in the editor, it works just fine.

Is there something wrong with my setup or is it a bug? If the latter, is there a quick work-around as tomorrow is the release?

Thank you

Did you figure out a workaround for this? We've encountered it as well.

Hey there! I'm from the team of the guy above :P Just solved it, it's an engine bug and I have filed a report. If you are interested, the issue is deep down in engine code, for now you can solve it by adding

 bIsWindow = true;

to the "Construct()" function of SVirtualWindow

As mentioned in the comment, I have filed a bug report already. We had encountered the same problem.

Issue was that the widget-path tracing required an SWindow to be on the top of the hierachy, but WidgetComponents use only SVirtualWindow's which do not have that bIsWindow flag set to "true".
