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"

Orientation Wrapping


I was trying to get quick prototype of Orientation Wrapping. I got some basic part working, (character rotate in the correct direction), what I'm stuck at is combing reorientation of character with animation switching in cardinal direction.

I just run out of ideas how to reliably calculate cardinal direction of movement of character. Calculating direction's of movement is quite trivial when character is moving only in one direction, getting all angles etc as well, but as soon character start turning or moving diagonally it all fall apart. And when combined with Reorienting of root bone, hell opens (animation just start to change directions seemgly randomly).

I wonder how the cardinal directions are calculated in Paragon, as they look really stable almost as per bone blend of different animations.
