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"

Level Sequence: Game crashes when "SetPlaybackPosition" is called by Sequencer

We've encountered a bug that leads to a complete crash of your application (editor + build) and here's how to reproduce it:

  1. Create a new level and save it

  2. Add a new level sequence to your level

  3. Add a new event track to your level sequence and add an event at a desired frame (for example: 50)

  4. Name the added event (for example: "SequencerEvent")

  5. Save your level sequence and open your level blueprint

  6. Get a reference to your level sequence and play it on "BeginPlay"

  7. Add a new custom event which is named after the sequencer event (in this case: "SequencerEvent")

  8. Put the execution pin of your custom event into a "SetPlaybackPosition" node and enter a valid time (for example: "0.1")

  9. Save all

  10. Playtest

  11. Unreal will crash

  12. Add a "Delay" node with duration value "0" right after your custom event before you call "SetPlaybackPosition". Unreal won't crash in this case

I've attached some screenshots that show the different repro steps: alt text alt text alt text
