Parenting layers is disabled if the platform type is HTML5 Canvas, which is what I am working in.
I have a robot arm with a claw. The robot arm should extend whilst the claw stays "parented". I've tried using the bone tool, which works for simple movement (keeping proportions etc), however because the arm needs to expand and there isn't parenting available, it makes for some tedious work (multiple arms moving rotating etc). Any suggestions how affixing the claw to the arm while it extends? Image left is the short arm and image right is the extended version.
