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"

Baffling nullptr bug

In my plugin I create a new node object using this line of code.

 Node = NewObject<UQuestGraphNode_Action>(QuestGraph, UQuestGraphNode_Action::StaticClass());

This line crashes and complains about a nullptr. I am completely stumped. As far as I can tell, i'm not even trying to access any pointers, so I have no idea why it would complain about a nullptr.

I have also tried instantiating the Node in this way, with no fix either.

 Node = NewObject<UQuestGraphNode_Action>(QuestGraph);

Any help would be appreciated, thank you.

i guess you checked if "QuestGraph" wasn't null (anyway it should throw an assert and not a classic access violation )

Could you tell us more, is it at the beginning of a method ? did you checked if the object you call this code on is not null ? could you show the few lines before and after this call ?
