Installing and Using @react-three/cannon in a React Application

To install @react-three/cannon using pnpm, you can run the following command in your terminal:

pnpm install @react-three/cannon

This will install the package and its dependencies. Make sure you have pnpm installed and configured correctly on your system. If you don't have pnpm, you can install it by following the instructions on the pnpm website.

After installing, you can import the package in your React application and use its hooks to add physics to your scene. For example, you can use the useBox hook to create a box with mass and position, and the usePlane hook to create a plane with rotation and position.

Here's an example of how you might use these hooks:

import { Canvas } from '@react-three/fiber';
import { Physics, useBox, usePlane } from '@react-three/cannon';

function Plane() {
  const [ref] = usePlane(() => ({ rotation: [-Math.PI / 2, 0, 0] }));
  return (
    <mesh ref={ref}>
      <planeGeometry args={[100, 100]} />
    </mesh>
  );
}

function Cube() {
  const [ref] = useBox(() => ({ mass: 1, position: [0, 5, 0] }));
  return (
    <mesh ref={ref}>
      <boxGeometry />
    </mesh>
  );
}

function App() {
  return (
    <Canvas>
      <Physics>
        <Plane />
        <Cube />
      </Physics>
    </Canvas>
  );
}

This code creates a plane and a cube, and adds them to a physics world. The plane has a rotation of -π/2, and the cube has a mass of 1 and a position of [5]. The useBox and usePlane hooks return a reference to the box and plane objects, which can be used to access their properties and methods.

Note that you'll need to have @react-three/fiber installed as well, as it provides the Canvas component that wraps the physics world.
