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"

Finding if two forward vectors face each other

Hello,

I am trying to find out if the forward vector of "Actor A" faces towards the forward vector of "Actor B" or if it faces away from it. I just cant seem to figure it out.

With the dot product of both forward vectors you can get which direction they are facing. If the dot product is greater than 0 both vectors are pointing in the same direction, if the dot product of both forward vectors is less than 0 the two vectors are facing in opposite directions.
