PhysX JS

PhysX for JavaScript.

This repo complements the work being done over at prestomation/PhysX to create emscripten bindings for NVIDIAGameWorks/PhysX. At some point the prestomation/PhysX fork may be merged into NVIDIAGameWorks/PhysX and this repo will be updated to track that repo instead.

This repo serves multiple purposes:

  • Provide a Docker workflow for compiling and building PhysX to WebAssembly via Emscripten
  • Provide a Docker workflow for adding new bindings (the whole PhysX API is not currently covered yet)
  • To publish WebAssembly files to npm (physx-js) so that they can be used in projects via npm or CDN

Example

There is an example with threejs and physx-js using Webpack in the /example folder. The example is also available to preview here, it's hosted on now

Usage via npm

npm install physx-js

The physx.release.js file can be imported via Webpack or included as a script on the page

The physx.release.wasm file needs to be served in a static/public folder so that it can be loaded in a browser environment

See /examples for how this can be used in Node, Browser and Browser w/ Webpack.

Usage via CDN (jsDelivr)

You may want to load the WebAssembly files via CDN, in which case you can use jsDelivr's npm mirror, loaded as a script:

<script src="https://cdn.jsdelivr.net/npm/physx-js/dist/physx.release.js">

You can also target a specific version:

<script src="https://cdn.jsdelivr.net/npm/physx-js@0.0.6/dist/physx.release.js">

Then configure this to also load the wasm file from the same place:

PHYSX({
  locateFile(path) {
    if (path.endsWith('.wasm')) {
      return 'https://cdn.jsdelivr.net/npm/physx-js@0.0.6/dist/physx.release.wasm'
    }
    return path
  }
})

Development

You may want to make your own builds from source, or modify the bindings yourself. The full PhysX API isn't covered yet but more will be added in the future.

The only dependencies you need to do this are Docker, Node and Npm. All other dependencies are managed inside the docker image.

The scripts run from this repo expect the repo prestomation/PhysX#emscripten_wip to be mounted here at ./PhysX.

// Install dependencies
npm install

// Generate the project (i believe this only needs to be run once, can take a while)
npm run generate

// Build WebAssembly files (physx.release.js and physx.release.wasm)
// This is all that needs to be run after making changes to bindings.
npm run make

These scripts will start a docker container, mount the PhysX source code and then build and compile it using emscripten.

The output files (js and wasm) are copied into ./dist

If you want to add new bindings, edit ./PhysX/physx/source/physxwebbindings/src/PxWebBindings.cpp and then run npm run make to rebuild.
