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"

By default - No it isn't. However you may tackle with the Actors inner code and add mutexes there to allow a thread safety.

The best way to do it would be actually to Spawn a Task (on a game thread) where you can set the actor location. And even better is to batch all the Actors and All the locations and set them all in 1 single Task -> the set code will ofcourse be on a game thread but all your calculations can be done on worker thread which probably can slightly or even more than slightly improve your performance.
