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"

What is Get Mouse X/Y based on?

Using the Get Mouse X/Y functions in a blueprint gives you some kind of mouse position delta value, but what exactly is this value? The description just says "Return the current value of input axis key Mouse X" which isn't particularly helpful in this case.

I first assumed it was how far the mouse had moved since last frame (in pixels) or something similar, but after some testing that is quite obviously not the case, or at least it's not in pixels. It's certainly something similar to this, is it maybe in a different format than I expected? Where exactly does the value come from?
