I want to know the objects affected by a radial explosion. I may destroy these objects. The V2 version in the source code does not seem to handle this callback function.

The callback for v2 is `affectedBodiesCallback`, see the example: [Physics V2 Helpers | Babylon.js Playground (babylonjs.com)](https://playground.babylonjs.com/#E5URLZ#5)
