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 do I rotate a lever like a joystick with only pitch and roll?

I'm trying to rotate a control stick in a plane toward a point in space - a VR motion controller. So I have 2 vector positions - root of the control stick, and motion controller. Using this I can approximate the user moving the control stick. It's like a lever, but in 2 axes.

I'm trying to figure out the best way to rotate the control stick. When I use MakeRotFromX, or Look Rotation, it pitches properly, but it yaws / rotates around Z. A real control stick only has Roll and Pitch. So it leans forward/backward, and left and right, but doesn't spin or rotate on Z.

What is the right way to have the control stick pitch forward toward the motion controller, and roll left/right toward the motion controller?
