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"

tick, network and vr camera update execution order

Hi, I'm trying to figure out how to get as smooth updates as possible in our VR multiplayer project. I haven't really found any comprehensive overview of the execution order of an entire update cycle in the GameThread. Perhaps you guys could help me wrap my head around this some more.

This is my current working theory:

  1. All tick groups get updated first (Here we have "old" values of VR pose and replicated props)

  2. VR Pose gets updated in the special lateUpdate tick group

  3. Cameras are updated

  4. TG_PostUpdateWork runs here according to the docs. However, this does not seem to be the case

  5. Scene is rendered

  6. Replicated props get buffered to history

  7. Depending on NetUpdateFrequency replicated props get sent over the network

Is this even remotely correct?

Feel free to just answer part of this question since there's a lot of subcategories to it. All feedback is very appreciated
