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"

Polymorphism and Blueprints Support

Hi

We are using Unreal 4.8.

We have a fairly basic class hierarchy in our Blueprints (APawn(code)->OurPawn (code)->BaseClass (Blueprints)->Multiple sub classes(Blueprints) )

Without getting into specifics, we are finding the support for polymorphism in Blueprints lacking and very fragile. For example:

  • Adding new functions to the base class or moving logic from a sub class to the parent frequently cause crashes deep in the engine. Attempting to refactor logic from a sub class to the base is a painful experience :)

  • Functions in the base class sometimes appear in the sub class in the override section, other times they don't. This feels like a showstopper if we can't rely on being able to override functions. There are posts about a hack to add a return value to force them to show, but we have found this isn't reliable.

Does Epic recommend anything beyond an extremely trivial use of inheritance in Blueprints?

Do you use it in any of your internal projects?

Thanks!
