Basic 3D rigid body physics simulation with spheres and arbitrary static geometry, demo running in the browser available here!
Controls:
- WASD: move forwards/left/backwards/right
- Space: move upwards
- Left shift: move downwards
- Mouse: look around
- Mouse left button: "shoot" a ball
- Escape: release mouse lock
- R: remove all balls from the scene
- T: stop/start time
- P: save the current scene into a file with name saved.scene (only works in the native build)
Additional scenes can be found in the folder called scenes. The scenes downloaded from this folder can be opened by drag-and-dropping one into the browser window while the app is running.
The same codebase is used across all build targets, with small differences between them. For the native build, CMake is used and for WASM there is a separate build_wasm.sh build script.
Emscripten is used to compile and build the WASM target so the latest version of emsdk should be installed and included in PATH. Can be built by running the script:
sh build_wasm.sh
After building the directory dest will contain the compiled webpage.
CMake (sudo apt install cmake on Ubuntu...) and SDL2 development library (sudo apt install libsdl2-dev) has to be installed before building, then build with:
mkdir build
cd build
cmake ..
make
The executable should be ready in the build directory along with the base.scene file.
