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"

MakeMap / MakeSet nodes do not exist

When I create a map variable and use a Set node to set its value without wiring an input to it, I get the following error message:

Error Default value '' for Map Variable is invalid: 'Map inputs (like 'Map Variable') must have an input wired into them (try connecting a MakeMap node).'

However, unlike MakeArray, there is no such node. There's no MakeSet for set variables either.

Still an issue as far as I can tell in 4.17. Anyone have an update on this?

You must manually add variable to this class, then go to its properties, and change its type to map or set with this button.
