Does anyone know how to dynamically constrain hand position during grab interaction?
I am using Quest 2 controllers represented as hands. Started with the Complex Grab sample scene. I've created a custom object with custom grab points, hand pose, etc. and that works fine.
What I have been trying to do is, if you have picked up an object the object + hand should collide and not be able to pass through a panel. Think of, for example, drawing on a board. You don't want the pen and hand to simply pass through the board.
I know ways to do this in normal Unity or using XRI Toolkit - it's a fairly trivial thing - but the Interaction SDK is not playing nice.
I also tried deconstructing the pin board prefab and using those OneHandTranslateTransformer and InteractableTransformerConnection components but I couldn't get it to work how I want. For one, they affect rotation as well as position but I just want to constrain position. In addition, those constraints kick in the moment you grab the object, but I need the constraint behavior to happen only when the tool (e.g., a pen) touches a specific object (e.g., drawing board). Couldn't seem to override this via script.
Has anyone done this before with GrabInteractable type of objects? Or more generally, is there a GameObject one can interact with for constraining hand position?
Thank you!
