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"

Many Actors causing Lag, need instancing? C++

I'm trying to find the correct way to instance a BP actor through C++. My original method of spawning my world causes an incredible amount of lag on even a high end system due to draw calls, but I've been unable to find a working way to instance everything and limit the lag.

I'm currently doing

     TSubclassOf<ATile> tile;        //Base tile object

 void ATileManager::SpawnTestWorld()
     FActorSpawnParameters spawnParams;
     spawnParams.Owner = this;
     for (int y = 0; y < WorldLength; y++)
         for (int x = 0; x < WorldWidth; x++)
             AActor* spawnedTile = GetWorld()->SpawnActor<ATile>(tile, FVector(x * TileWidth, y *TileWidth, 0), FRotator::ZeroRotator, spawnParams);

Obviously this isn't efficient, and a 100x100 map drops my fps from 120 -> 15-30. I know I have to add an UInstancedStaticMeshComponent to my class, but I am unsure of how to utilize it from there.

Any help would be appreciated,

Thank you
