Length of any object or console.log or print

[betotulkas]

For the ik bone i need the distance between two point, the knee and the shoe. But this is less time if i obtain by console or any other idea, too the console work for know if any function is right .for this type of animation the distance and length. And because i can't work whit $value, translation.y and translation.x, $value in the same x and y of any object.

If I'm not mistaken, you should use an empty object. Add a custom property and fill it with your formula.

Yes is like your example ik, but is the work of create all, in your example are C2, B1, A2, A,B,C. And the properties too. If the script is for one object is ok, but more is hard time. But is for the way of friction. I left my hand to circle intersect. but your idea work perfectly.

Yes, it takes a lot of time. We need a programmer who understands how IK works so that IK bones no longer need to use expressions.

Hopefully, a team from Blender will want to help Friction2D. Haha...

In blender you can access to all code by python. In his console. I don't know if the code of ik is there. some day i look to it.
