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"

Question about blueprint communication

I m having a problem with blueprint communication. I've made a blueprint which makes the music in the background stop. I want that when i press an UMG button it will then stop the music. But when i use it, it says: "This blueprint (self) is not a Wind_Sound_Effect_1, therefore "Target" Must have a connection". Please look at this screenshot: http://i.imgur.com/6mZC1ft.png?1

I don't know if this will work, but you can try to make an variable which is a reference to your windsounfeffect, and connect that variable to your stop wind breeze.

Like I said I haven't tested this, but it might be worth a shot. Reason that you get this error btw is quite simple, you are calling a function from another blueptint it seems, and the self reference in your graph from your widget is a reference to that graph and not to the bp where the function is. another solution might be a cast but for that I would need to know some more stuff of your set up.And even than I can't garantee that it will work.
