I’m facing a situation that can only import es6 module, can not use <script> tag. How to convert ammo.js to es6 module? If can’t convert, is there a way to wrap it in an es6 loader, and load it like what DRACOLoader loading draco_decoder.wasm?

I suggest you use the JS version instead of wasm (because wasm is a pain to wrap and performance difference with ammo specifically is quite low) make a local copy (or clone repo) go to the bottom of the file and add an export statement profit?

Oh! There’s an ammo.js file in the official ammo.js repo. ( I consider EMScripten can only produce .wasm not .js before, and three.js repo only has ammo.wasm.js and ammo.wasm.wasm files too. ) Thanks a lot! I’ll try.

OK! I found need one more step: delete this.Ammo=b; in ammo.js, otherwise will cause an error. Seems to work fine: demo code [image]

Sorry that I chose to use cannon-es and PhysX wasm later. So no more use of ammo.

[image] gonnavis: cannon-es and PhysX wasm Thank you very much for reply. I use cannon-es too but I hear about physx-js at first time. It needs for me to have the same physics engine on Web and Desktop (C++ client) for multiplayer game: Ammo.js and Bullet Physics. I must have the same physics…

We are using a customized PhysX wasm. https://github.com/webaverse/app-wasm/blob/e7f13f911e1b493672a42495040657445f2de5bb/objectize.cc https://github.com/webaverse/app-wasm/blob/e7f13f911e1b493672a42495040657445f2de5bb/physics.cc Not full-featured yet, but expose functions for our project’s needs…

Thanks a lot! Maybe I will try it later. I will use cannon-es with TypeScript and Parcel for a while.

is ammo unmaintained as well now? otherwise why don’t they just release an es export?

Ammo.js isn’t a separate library. This is just a direct build of C++ Bullet Physics code using Emscripten. You can get the Bullet Physics source code and build it yourself to JS. I think this is an Emscripten issue. If I’m not mistaken.
