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"

Why synchronous loading flush async loading

 //
 // Begin loading packages.
 //warning: Objects may not be destroyed between BeginLoad/EndLoad calls.
 //
 void BeginLoad()
 {
     auto& ThreadContext = FUObjectThreadContext::Get();
     if (ThreadContext.ObjBeginLoadCount == 0 && !IsInAsyncLoadingThread())
     {
         // Make sure we're finishing up all pending async loads, and trigger texture streaming next tick if necessary.
         FlushAsyncLoading();
 
         // Validate clean load state.
         check(ThreadContext.ObjLoaded.Num() == 0);
     }
 
     ++ThreadContext.ObjBeginLoadCount;
 }

In the function BeginLoad, unreal will flush aync loading when this is invoked by synchronous loading request(staticloadobject). But why? Can someone help me to explain it? For a example?

What's more, it just flush the time-sliced async loading, not threaded aync loading.

Many thanks!
