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"

Whenever I spawn blueprint actor in c++ the editor crashes

Whenever I attempt to spawn blueprint object c++ it fails. UBasicUnit, is a blueprint actor with the parent class being Ar1_CPPtoBPCharacterTransition which is a c++ class. The place I'm trying to spawn it out of is a blueprint class that has a parent of AArchwaySpawn. Whenever this function is called, the editor crashes and I can't figure out why.

AArchwaySpawn.h file

 UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Ai To Spawn")
     TSubclassOf<Ar1_CPPtoBPCharacterTransition> uBasicUnit;

AArchwaySpawn.cpp file

   FActorSpawnParameters SpawnParams;
     if (AiToSpawn == EAiToSpawn::BasicUnit) {
         GetWorld()->SpawnActor<Ar1_CPPtoBPCharacterTransition>(uBasicUnit, GetActorLocation(), GetActorRotation(), SpawnParams);
