How to import GrabVR

npm install grabvr

Import into your code

import GrabVR from 'grabvr'

Instantiate And Use

Create a GrabVR object.

const grabVR = new GrabVR()

Create some Object3Ds and add then to the GrabVR grabables.

const box = new THREE.Mesh(
    new THREE.BoxGeometry(1.0, 1.0, 1.0),
    new THREE.MeshBasicMaterial({
        color: 0xff0066,
        wireframe: true
    })
)
scene.add(box)
grabVR.grabableObjects().push(box);

Add your VR controllers to the scene (see example code for better understanding)

const controllerGrip0 = renderer.xr.getControllerGrip(0)
controllerGrip0.addEventListener("connected", (e: any) => {
    controllerGrip0.add(lefthand)
    grabVR.add(0, controllerGrip0, e.data.gamepad)
    scene.add(controllerGrip0)
})

Update in the render loop.

grabVR.update(clock.getDelta());
renderer.render(scene, camera)
