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"

Can no longer use any fixed array as uproperty

Hi guys,

I just upgraded my source 4.6 -> 4.7 and ran into a problem. I used to have an exposed c-array of USTRUCTs (FTileEdge), like so :

 UPROPERTY(EditAnywhere, BlueprintReadWrite) FTileEdge m_edges[4];

working well. It seems like c-arrays are no longer allowed so i have been trying to switch this to a TArray of some sort.

 TArray<FTileEdge, TFixedAllocator<4> > m_edges;

Will fail with "missing >" which it is not. and all the "TStaticArray" variations fail as "Unrecognized type" no matter what i include.

So how do we expose a fixed size array of ustructs now?

Try remove BlueprintReadWrite from that property.

You are correct, thanks alot m8. I just took for granted that it was the actual c-array that was the problem. Never assume anything :).

The problem still holds for the others (TArray with TFixedAllocator and all the TStaticArray), but I guess there is no need for the headertool to support them if the c-arrays work well.
