Add physics to Instance component

[netgfx]

How would one add physics (cannon) to an Instance ? Tried with [ref] = useBox() but that did nothing.

Some example code would help sort out your issue.

If you're using @react-three/cannon, don't forget to wrap your physics objects in the <Physics> component.

Here is a working example https://codesandbox.io/s/usecannon-physics-basic-example-y2t7tu?file=/src/index.js

Unfortunately I don't think this is the answer, as the code example doesn't use <Instances> or <Instance>.

It's certainly possible to use @react-three/cannon with an instancedMesh as in this example: https://codesandbox.io/s/r3f-cannon-instanced-physics-g1s88?file=/src/index.js

However, I'm also struggling to find an examples where something like useBox has been integrated into an <Instances> or <Instance> component. Are there any other ideas?

it doesnt really make sense to mix drei/instance and physics. the whole point of drei/instance is that you are able to control the instances position, but when you couple an object with physics then the physics-engine controls position. react-three/cannon can handle instances out of the box without you having to do anything.

I have a problem with this, it does works as intended using useSphere(), but when using useBox() it only collides with usePlane() object but not useTrimesh() ones. It's weird.
