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 for Automated Door

I am learning how to create an automated door...

My basic logic is to create cinematics to mimic the open&close.

In Matinee and Level Sequence, there are two keys: Key1 is for open state and Key2 for closed state.

Then I use the trigger to control whether to open&close the door by BP (a timeline controlled by Play and Reverse in BP). When I walk into the trigger, the door is open(K1 -> K2); I get out of the trigger, the door reverse back(K2 -> K1).

When using Matinee, it works perfectly.

But problem comes when I use the level sequence. When the door is open and level sequence ends at the K2, the door closes immediately and level sequence go back to K1. That scene just likes that a video ends and goes back to its initial static picture(the first frame of video) .

Actually I don't know what's the difference between these two. Here is my BP for LevelSequence. I write it in LevelBP.

Thank you all alt text

On the tracks in sequencer, there should be a property called "When Finished". You should see it if your right click on the track section area in the "Properties" menu. Set it to "Keep State". Let me know if that doesn't work.
