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"

How do I wake phsyics objects at a certain keyframe?

Dear community,

I'm making a VR experience and have zero programming skills. I have around a 100 props that need to start floating at a certain keyframe. There is an old video *(using UE 4.6: https://www.youtube.com/watch?v=tExfWojQe_w)* that shows how to do it in Matinee with one prop, but I found it rather difficult with a 100 props.

What is the workflow with level sequence to wake physics objects at a certain keyframe? Or is there an total different way to make objects float instead of physics?

Thanks in advance!

Best way to do anything not already integrated in Level Sequencer is to use Event Tracks, listening to those events in your BPs, and do everything you want to do from there.

I suggest to read this page for further info: https://docs.unrealengine.com/latest/INT/Engine/Sequencer/HowTo/TracksEvent/-

In your case you can add an Event in your Level Sequence and from the listener to that event (in your BP) do what you want with your physics affected actors.

Thanks! This headed me in the right direction.

Only thing is in the tutorial he is using a vector to translate a cube. How can I make an event that talks to the physics checkbox? If I select an bolean instead of the vector in my structure, I only get a checkbox but cant specify the command.

Everything else seems clear! Just that one part where I can make the event communicate something different then translation is unclear to me.
