To configure and build ammo into the builds directory, run the following:
In order to build ammo.js yourself, you will needįor more information about setting up Emscripten, see the getting started There is experimental support for binding operator functions. Please submit pull requests with extra stuff that you need Not all classes are exposed, as only what is described in ammo.idl is You find a case where you need the float& method, please file an issue. You can do |new btVector3(5, 6, 7)| and it will work as expected. Time you call such a function, making usage very ugly. In C++, but from JavaScript you would need to write to the heap every The reason is that float& is basically float* with nicer syntax However their performance is potentially problematic.įunctions returning or getting float& or btScalar& are converted toįloat. JavaScript getters and setters could give a slightly nicer API here, Will get m_rayToWorld from say a ClosestRayResultCallback. Setter and getter functions, that are prefixed with |get_| or |set_|. Member variables of structs and classes can be accessed through For example,Īmmo.btVector3, etc., as you can see in the example code.
Instructions for how to use the wrapped objects.Īll ammo.js elements should be accessed through Ammo.*. There are however some differences and thingsįor a description of the bindings tool we use here, which includes In particular see the WebGLĮxamples/webgl_demo/ammo.html Bindings APIĪmmo.js autogenerates its API from the Bullet source code, so it shouldīe basically identical. In that directory might be useful as well.
That is HelloWorld.cpp from Bullet, translated to JavaScript.
If, on the other hand, you want to write code in JavaScript, you can use theĪutogenerated binding code in ammo.js. In both cases, you don’t need ammo.js, just plain Bullet. Or you can use Bullet directly from emscripten-ports, with -s USE_BULLET=1. Normally and either build and link Bullet using If so, then you can build your C++ code with emscripten The most straightforward thing is if you want to write your code in C++, and ‘ammo’ stands for “Avoided Making My Own js physics engine by compiling bulletĪmmo.js is zlib licensed, just like Bullet.ĭiscussion takes place on IRC at #emscripten on Mozilla’s serverīuilds/ammo.js contains a prebuilt version of ammo.js. Some part of the Bullet API that is not supported that you need, please see Note: ammo.js has just been updated to a new porting approach. The sourceĬode is translated directly to JavaScript, without human rewriting, soįunctionality should be identical to the original Bullet.
