Descrizione
Creating constraints between instanced meshes isn't possible at the moment.
From #48 @drcmda
we could maybe learn from react-springs playbook here, esp useSprings: https://www.react-spring.io/docs/hooks/use-springs
const [refs, api] = useDistanceConstraints(10000, () => ({ ... }))
return data.map((id, index) => <mesh key={id} ref={refs[index]} ... />
I think this would be a good pattern for constraints on instanced bodies. An iterator function that returns an array of two indexes could attach a standard mesh to instanced meshes or instanced mesh to instanced mesh.
const [bodyA] = useBox({...})
const [bodyB] = useSphere({...}) // ref for instancedMesh
useDistanceConstraints(count, bodyA, bodyB, fn: (i) => [0, i], options, deps]) // where fn returns [bodyAIndex, bodyBIndex]
