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"

[Closed] Component instance cached data

Hello, this API has recently been changed (in 4.3). In order to achieve data caching we need to override UACtorComponent's

 virtual FName GetComponentInstanceDataType() const override;
 virtual TSharedPtr<class FComponentInstanceDataBase> GetComponentInstanceData() const override;
 virtual void ApplyComponentInstanceData(TSharedPtr<class FComponentInstanceDataBase> ComponentInstanceData) override;

This is all great, but FComponentInstanceDataBase is not exported from Engine module (no ENGINE_API) in front of it. Which basically produces link errors when you try to use all of this functionality in a plugin.

Is this a bug or am I crucially missing something here? Thanks
