[x3d-public] [create3000/sunrize] Joe doesn't kick or move in sunrize. (Issue #6)

[John Carlson]

So, I did some research.  Here’s what tooltips says:


*[joints accessType inputOutput
<https://www.web3d.org/x3d/content/X3dTooltips.html#accessType>, type
MFNode <https://www.web3d.org/x3d/content/X3dTooltips.html#MFNode> array,
empty list] [HAnimJoint
<https://www.web3d.org/x3d/content/X3dTooltips.html#HAnimJoint>]*
The joints field contains a list of USE references for all HAnimJoint node
instances found within the preceding skeleton hierarchy.
*Hint:* order is irrelevant since names are contained in the original DEF
objects.
*Hint:* these USE nodes can be utilitized by inverse kinematics (IK) and
animation engines.
*Warning:* *the number of contained <HAnimJoint USE='*'
containerField='joints'/> nodes at top level of HAnimHumanoid needs to
match the number of corresponding HAnimJoint node instances found within
the preceding skeleton *hierarchy.
*Warning:* top-level HAnimJoint USE nodes must include
containerField='joints' for proper validation and operation

The first warning is the relevant one.

I am not sure about the standard.

Perhaps we’re talking best practices.
