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"

Getting SpawnObject wrong class: None error, but only in build

I am using a C++ class (inheriting directly from UObject) for a call to ConstructObject in BP. It constructs fine and operates correctly when run in-editor. However, when the game is built (Shipping), it does not work correctly, and I find the following error in the log:

LogScript:Error: UGameplayStatics::SpawnObject wrong class: None

I get no such entry in the editor's log.

Potentially related information:

  1. ConstructObject is being called in a WidgetBlueprint. Does that not work correctly?

  2. I've already tried using an empty child BP class in place of the C++ class.

  3. I get no errors or warnings from the build log relating to that specific class.

Product Version: UE 4.10
