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 can I SpawnActor in Thread?

I tried std :: Thread and it says Crash. Is there another way?

Don't use standard C++ library with UE4, aspecially in such sensitive matter as multi threading. UE4 provides it's own implementation and you should use it so UE4 is aware of thread creation:

https://wiki.unrealengine.com/Multi-Threading:_How_to_Create_Threads_in_UE4

But it might be still impossible to what you trying to do, UObjects should not be used else where then game thread, you most likely get crash with error informing you about it. You could make illusion of asynchronous spawns by doing that on tick when you green lit with some variables, you can also spread it across few frames if you thinking about performance. Explain your case, we might figure some alternatives.
