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"

this is my solution:

 LineBatchComponent = CreateDefaultSubobject<ULineBatchComponent>(TEXT("LineBatcher"));
  TArray<FBatchedLine> lines;
         for (auto i = 0; i < mVertexes.size() - 1; i += 2)
         {
             FVector start = FVector(mVertexes[i].x,mVertexes[i].y,mVertexes[i].z);
             FVector end = FVector(mVertexes[i+1].x,mVertexes[i+1].y,mVertexes[i+1].z);
 
             FBatchedLine line = FBatchedLine(start,
                 end,
                 FLinearColor(1, 1, 1, 0.5),
                 10000, // for long period draw
                 0.3,
                 4
             );
             lines.Add(line);
         }
     }
 
 
     LineBatchComponent->DrawLines(lines);
