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"

Foot IK for quadruped

Hello, everybody! Recently i have started making a simple game, just for experience and i though - can i make a foot ik for the cat skeleton. I have seen a lot of IK tutorials on 2 bone inverse kinematics, but none for quadrupeds. I played a Boy-Kite demo and the animals in there had the IK but i have no idea how to do that. So if anybody could help me it would be great!alt text

The ik system is gonna be exactly the same as if you do for a biped . Apply simple IK for all 4 legs and move down the chest and hip down accordingly through ray trace .

Do the animals in the Kite demo actually have quad-IK or did they just put the root bone in the center and rotate the root/capsule to match the slope of the ground? That still requires some math but not as much as IK on all 4 legs.

I don't remember any rough terrain in the demo that would have required IK, just gently sloping hills covered in grass that would have hidden most misplaced feet.
