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"

std::vector to TArray

I am trying to convert this line of code in to UE4 C++

 //defenitions
 //std::vector lines;
 //size_t numObstLines;
 
 std::vector<Line> projLines(lines.begin(), lines.begin() + static_cast<ptrdiff_t>(numObstLines));
 
 How would I convert this std::vector constructor in to TArray syntax ?
 Like if I had a :
 
 //TArray<FLine> lines;
 //int32 numObstLines;
 
 TArray<FLine> projLines(???);
Product Version: UE 4.19

Assuming numObstLines is the number of elements to copy from lines then you can do

 TArray<FLine> projLines(lines.GetData(), numObstLines);
