Warping

Keep track of

• Camera look direction
  • Use to calculate relative rotation to transform.rotation
• Move direction
  • Use to calculate relative rotation to transform.forward

OnAnimatorIK

Stride

• Set foot IK goals and weights
  • Get goal positions
  • Add/subtract in forward direction based on speed

Look

• Use look direction to get look position
  • lookDirection = mainCam.transform.forward
  • lookDirection.y = 0f
    • Clamp to XZ plane
  • lookPosition = transform.position + lookDirection
• SetLookAtPosition with look position
  • Rotates upper body

OnAnimatorMove

Movement

controller.Move(transform.position + transform.forward * speed * moveRate);

Rotation

• moveRotation = Quaternion.AngleAxis(Vector3.SignedAngle(transform.forward, moveDirection, transform.up), transform.up)

• Get difference between move direction and look direction

  • difference = Vector3.SignedAngle(moveDirection, lookDirection, transform.up)
  • If difference > or < than max/-max
    • Add difference to move rotation
      • moveRotation *= Quaternion.AngleAxis(difference - max or + max, transform.up)
    • Set animator float for rotation
      • Triggers turn in place animation if idle
      • Triggers lean if moving

• Rotate transform to move rotation

  • transform.rotation *= moveRotation
  • Will be 0 rotation when look direction is inside max range and transform forward = move direction
