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"

Initialize object of custom class from blueprint

Hi guys,

I've created a C++ class called "Item" that holds an array of another class of mine, named "ItemEvent". This works fine if I add events via C++, but for ease of use I'm trying to enable the addition of events via blueprint also.

I have several blueprints that derive from "item". Item has a function named "AddEvent" which accepts a pointer to an ItemEvent and simply adds it to the existing TArray. My issue is that, when I create new variables in my blueprint of my various ItemEvent types, they are never initialized by default.

I have begun trying to call the following node on the BeginPlay event to initialize these objects: https://docs.unrealengine.com/latest/INT/BlueprintAPI/Game/ConstructObjectfromClass/index.html

My issue is that this does not work, and provides the following error: alt text

The object "SwingOneHandedWeaponEvent" is a really simply C++ class derived from ItemEvent. No matter which class I pick here, I seemingly always get the "wrong class to spawn" error.

Am I going about this incorrectly? All I wish to achieve here is to initialize the variables that I include on my blueprint when the object is created at runtime, so when I access them later they are not null.

Any and all help would be greatly appreciated!
