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"

How to set default value to "self"?


How can I get my function on the left to have the same "Target [self]" pin as the one on the right?

looking for this, myself.

From what I can tell:

for C++ defined functions: use UFUNCTION metadata 'DefaultToSelf = <paramname>' and it looks like you can set only one parameter per function to use this feature.

Sadly, I don't see any path to using this in a blueprint-only implementation that doesn't require engine changes. That being said, I don't think it would be difficult. Something like, in UEdGraphSchema_K2::TrySetDefaultValue - compare with the meta keyword before doing the package lookup.

Alternately, exposing various other of the meta functionality to functions in the advanced interface would be nice.

I am guessing here, but can't you just put the right one into a variable and read it from there to the left one?
