Bullet Physics for Heaps

Bullet

Bullet Physics wrapper for Heaps

Supports both HashLink and JS output thanks to WebIDL

Compilation

• Clone this repository

• Run the following commands, they download the Bullet physics library into the lib dir.

git submodule init
git submodule update

• Make sure you have hashlink installed in two directories above the current one:

/hashlink <- hashlink git repo
/libs
   /bullet <- the current git repository

HL Target

• First run haxe bullet_hl.hxml, then check the platform specific instructions:

Windows

• Run CMake, and make sure the variable HASHLINK_DIR is correct.
• Compile the created Visual Studio solution.
• Place bullet.hdll where you have your other .hdlls

MacOS

• Currently compiling only works with GCC
• Install CMake: brew install cmake
• Install GCC: brew install gcc
• Run the following command, and make sure the paths to gcc and g++ are correct
  • cmake -DCMAKE_C_COMPILER=/usr/local/bin/gcc-9 -DCMAKE_CXX_COMPILER=/usr/local/bin/g++-9 . -G"Unix Makefiles"
• Build: make
• If compilation was successful, install the .hdll
  • make install

Linux

• This should work the same way as MacOS, except install GCC and CMake using your preferred package manager.

JS Target

• Install the webidl haxe package: haxelib git webidl https://github.com/jefvel/webidl.git.

• Install Emscripten

• Make sure the env variable EMSDK is set, pointing to the emsdk directory.

• Run haxe bullet_js.hxml

This should generate the files bullet.js and bullet.wasm.

Check out the sample html and haxe file on how to load it.

Building the Sample

First compile bullet as shown in the compilation section. Once that is done it should be possible to build the samples.

(You have to add the haxelib locally):

haxelib dev bullet $(pwd)

After building the JS sample, make sure to copy bullet.js and bullet.wasm into the sample directory.
