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"

EditInstanceOnly works on Actors but not on components

hi,

this is C++ related only.

UPROPERTY(EditInstanceOnly, Category=InstanceOnly) float InstanceOnlyProp;

If this property declaration is placed on any AActor class, it's not visible in BP editor as it should be. This is not the case if the same declaration is used in UActorComponent class. The property is still visible and editable in this case.

Is this bug or intent?

Thank you,

Cooper

Hey Jiri-

The behavior when added to an actor is expected. The EditInstanceOnly specifier means that the property is only available for edit on individual instances of the actor. It would also make sense that adding the property to an actor component treats each component added to a blueprint as an "instance" of that component, which is why it does appear in the blueprint in this case. I'm not positive if this is accurate however, and have entered a bug report, UE-30735 to investigate the behavior.

Cheers

Doug Wilson
