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 execute code on the Game thread from an FRunnable thread?

Hello, I have an FRunnable thread that is checking if data has been received on a few FSockets. Whenever specific data arrives from the sockets, I want to execute code on the game thread.

How can I execute code on the game thread from the FRunnable thread?

Easiest way is to create your own queue of things to run on the game thread. Then poll that queue to execute the task when present. You can see an example in the Steam OSS

Ok that's pretty easy. Is there any way to schedule something on the task graph from within my FRunnable such that I don't have to poll the queue? I would like everything to be as automated as possible

You can't safely access game thread data from another thread whether it's a monolithic or task graph thread
