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 to modify UObjects from custom thread?

I have written a custom thread derived from FRunnable, and I want to modify and apply some variables such as GameUserSettings and ViewTarget from this thread. But when I run these code below, the editor triggered a breakpoint at the engine source code and the comments said: CVar Changes can only be initiated from the main thread.

 GEngine->GameUserSettings->ScalabilityQuality.EffectsQuality = atoi(split[6].c_str());
 GEngine->GameUserSettings->ApplyNonResolutionSettings();

Is there any way to do it or can I delegate these task to GameThread?

Thanks a lot!

update: I found a class "FEvent" which seems to be useful about this problem,but I don't know how to use it...

I believe break points should only be triggered in debug and development configuration so I would try the shipping configuration; just for experimenting though, you should see the documentation more but for trying and experimenting I would try that. It would be weird if your shipped game suddenly triggered a break point; I believe though the alternate response of the engine is to simply crash but try it out.

I'll try it later... It takes a long time to rebuild the project in shipping mode... update: I think I cannot use shipping mode because this thread is in an editor plugin...
