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 MAX_PACKET_HEADER_BITS set to be 15 rather than 16 in the version higner than 4.12?

I find a problem that the NET packet doesn't send success from server to client until I set the MAX_PACKET_HEADER_BITS to 15 which is same as the new version.

So I want to ask that in the version4.12 the value MAX_PACKET_HEADER_BITS is set to be 16 but 15 in version4.14. Why do this change in the progress of version upgrade?

UE4.12 NetConnection.h line 28

enum { MAX_PACKET_HEADER_BITS = 16 };

UE4.14 NetConnection.h line 29

enum { MAX_PACKET_HEADER_BITS = 15 }; // = FMath::CeilLogTwo(MAX_PACKETID) + 1

Hoping for your reply~
