Well darn...that's interesting. I'll have to find out if there is a way to move the effectors within the game mode live. That would solve that problem.

BTW I had to rebuild the pivots, the bio ik adds a rotation if the pivots are not in alignment with one another. No big deal, just added more time.

Ah, I had weird flips in my rotations too...I added another effector to balance it out, but now you are saying this, I guess I should go back and check my pivot points too!

Fixed it, pivots have to be in perfect alignment, i was just attempting by eye as i didnt think it was critical and was off by a fraction,. So this time i aligned them with numerical accuracy, works perfect.

Sweet, I got the script to extract the rotations ready...it needs to be attached to all child nodes which have a running BioIK joint!

using System.Collections;
using UnityEngine;

namespace BioIK {
    public class TransformValue : MonoBehaviour {

        public void Update() {
            Debug.Log(ReadValues());
        }

        private Vector3 ReadValues() {
            BioJoint joint = this.GetComponent<BioJoint>();
            if(joint != null) {
                return new Vector3((float)joint.X.GetTargetValue(), (float)joint.Y.GetTargetValue(), (float)joint.Z.GetTargetValue());
            } else {
                Debug.Log("No joint found for " + name + ".");
                return Vector3.zero;
            }
        }

    }
}

Nice!

Here is the video of the current set up. Sorry I'm out of it, from being tired. Had to rebuilding the rig 4 times. So I am droning on a bit in the video.

This is very cool. For head neck, shoulder, arm joints this will work very well, but I think there will be some challenges with moving his legs, knees, feet etc. The required physics to ensure JD doesn't face plant into the ground will be quite complex. When JD walks, stands up, sits down etc is a sophisticated balancing act of movements and so we are going to need a physics engine or some form of machine learning algorithm that is configured to understands the relationships between components to define how, when and where the legs can be moved to ensure he remains in a stable position, or we will lift one leg and he will simply fall down.

Amazing progress.

Unity does indeed have a built in physics engine. I'm currently looking into how to implement it with IK. A floor will be helpful!
