How to get the joints between a starting joint and end joint? (Joint hierarchy)

[E7LK (Elk)]

Hello,

I’ve been at this for a while and somehow haven’t found a reliable solution yet, not from myself, or various sources online which is why I’m here.

I’m looking for a way to get a joint hierarchy from a ChainRoot and EndEffector much like how the IKControl instance does before applying inverse kinematics.

For instance,

print (GetJointHierarchy (RightShoulder, RightWrist)) 

would print

{RightShoulder, RightElbow, RightWrist}

So far the most I know for sure is that an iterative approach should be taken.

local function GetJointHierarchy (ChainRoot, EndEffector)	local Hierarchy = {}	local CurrentRoot = ChainRoot	while CurrentRoot ~= EndEffector do	-- Proceed to next root	-- Add to Hierarchy	end	return Hierarchy end 

As you can see, I need help with practically everything.

The most difficult part will be ensuring that the function considers the possibility a single root might diverge into multiple paths, with only one reaching the EndEffector.

This has been really scratching my brain, so please; any help is appreciated.

Add the current root’s name to the hierarchy. If the current root is the EndEffector, break the loop, Iterate through the children of the current root to find the next joint (either Motor6D or Bone ). Update CurrentRoot to the next joint’s Part1 .
