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"

Game crashing when running Standalone from the editor

The project runs well on the editor and package build, but it would crash if running on Standalone mode from the editor. It seems it has something to do with UChildActorComponent, but it still happens after I delete all the actors that has child actor in the scene.

I'm not sure about that but it might be because you are using some editor-only blueprint classes (or components). I had a similar issue with my project where some actions would crash standalone play. Turned out I was using an arrow component in my character blueprint that was editor-only, so it wouldn't be accepted as a valid class when trying to play in standalone or from a packaged build. I just had to replace this specific component with a normal arrow component.

Check if you are using some of these elements in your project and try to replace them with their non-editor counterparts.

Thanks for your insight, I'll check whether that is the case for my situation. Could you talk a bit more about the editor-only component? like what makes it editor-only?
