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"

How to align Z axis of two actors?


I have an actor with two sockets defined. On each of these sockets there are two other actors. Each of these socketed actors have their z axis (Up direction) pointing in a direction of my interest, relative to the parent actor.

What I want to do is to align two parent actors, by the actor in the sockets I click, facing each Z axis to the opposite.

I have started implementing this calculating the cross product of the Up direction of each socketed actor, to use it as a axis rotator, and then calculating the angle between them, but it seems that I have to take into consideration many cases (cross product being a 0 vector, angle sign, etc).

Is there a more direct way to do this calculations?
