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"

Duplicate an actor including its composite actors

For a simulation I am trying to duplicate an actor including all its composite actors.

I have a testing-environment (Arena) and the environment contains a set of targets and a set of agents (both stored in TArrays as UPROPERTY() )

I would like to, at some point in the simulation spawn a bunch of exact copies of that testing-environment (and thus including its targets and agents) in the exact same state as the original. (ideally even including its exact physics states). I have tried the following:

 FActorSpawnParameters SpawnParameters;
 SpawnParameters.Template = this->Arena;
 APC_Arena* AnotherArena;
 AnotherArena = GetWorld()->SpawnActor<APC_Arena>(SpawnParameters);

but this just copies just the Arena, not its composite actors.

Thank you for your time!
