Rotate or translate an object during grasp event Leap-motion

[haider482]

Can i rotate or transform an object during the grasping event of the leap motion i actually have some custom made maya 3d objects that i want to hold in correct position in hand. any help or suggestions will be helpful an example perhaps will be great. Thanks.

A few ideas:

Make the mesh a child of the gameobject with a collider, rigidbody and interactionbehaviour

Have an event listener that adjusts rotation OnGraspedMotion, OnGrasped, or on GraspStay

Use one object as a handle (with rigidbody, Interaction) and put update the position of your model (not childed) OnUpdate to match the handle.

I will try adding an event listener and adjust the rotation thank you for your reply i will let you know how did it go.

i tried with the onGraspedMotion but as i have some surgical tools in the environment so the mesh is not that good or big for holding it. The tool keeps slipping and bouncing from my hand collides i guess. But i do need something like this that's sure. There is an other issue also, i have some tools that are designed in two parts. These surgical tools work like scissors. To provide motion to these tools, i have used the getFistStrength method for now and directly mapped the values to the tools rotational movement. but still i need to map these tools to my hand for positioning them where ever my hands go.

For problems with collisions, you can customize the layers on the InteractionBehaviour, and set the tools to a layer that doesn't collide with the hands or other Interactable Objects when they are in motion. Our dynamic geometry project required a similar solution. Let me know if you want more information in this direction, and I'll send this forum to the dev on our team that implemented it.

EDIT: However, the scissors motion is something that we have not be able to accomplish. I'd be interested to hear if you have any success with that!

I am in a similar position wrt the Scissor action. Any updates on that ?
