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"

Issue in using Set Integer (by ref) in a macro

Hello, I am trying to set the value of an integer by reference in a macro created in my blueprint script. I was using one of the maze generating tutorials and the function throws a failed to resolve term Value passed into Target error. I am not sure why it cannot deduce the type of Value. The original tutorial was made in UE 4.6, so could it be due to updates made in UE 4.16? I have attached a screenshot of my blueprintalt text

Product Version: UE 4.16

This usually happens when the macro is called and the referenced variable is not valid / not plugged in outside the macro itself. Make sure all 'plugs' are connected. Another alternative would be, as mentioned in other forums, use the IncrementInt (++)

I'm not sure i understand what "called and the referenced variable is not valid / not plugged in outside the macro itself. Make sure all 'plugs' are connected" means. I can't think of a way in which it makes sense. Perhaps an example? Thanks in advance.
