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"

Why is a Static Mesh with Collision not Blocking When Moving in Timeline

I have a blueprint Actor and made a door with a frame, door and a door handle. All have collision set and when I try to run through the door I cannot pass through. Perfect. However I have input set up so that when the player gets close to the door they can hit a button and the door will open or close using a timeline. The problem is that when the player hits the correct button and the doors move to either open or close, while they are moving I can move right through the doors. When the doors are done moving the collision is back to normal and I can't walk through the door. This is how collision is set up on the door. Any guesses on why I can walk through the door while its moving?

Could you provide a screenshot of the blueprint you are using to play the timeline, as well as the timeline itself if you don't mind? I'd like to attempt to mirror your setup as closely as possible so I can get an accurate test case.

Done. Its a weird issue. I noticed this from standing still in frot of the door and opening the door. They pass right through me and when they stop I can no longer walk through them. However if I stand back, open the doors and while they are opening run towards them I do not go through. It only happens if I am standing still as the doors are opening or closing.

Thank you for the clarification. After some research, I have discovered that this is currently a known issue that relates to having a collision that moves over time. Until the player moves initially, the moving collision will not react to the player. This issue is in our database at (UE-10172).

Have a great day

Yes I kind of had a suspicion that this might be a bug. Thanks for looking into it.

Has this problem been fixed? I am doing something similar and it messes up. I am using a matinee movement track to move a blocker and the collision does not work when my character is standing still.
