Simple 3D reincarnation of Sokoban running in Google Chrome Native Client on top of Magnum OpenGL engine. Your target is to push all the boxes to their destination places.

Screenshot

Playable version is available on http://nuclearwhales.github.io/push-the-box. Please be patient, it will took a while before it loads -- the executable has around 4 MB. If you encounter any problems, please let us know :-)

Browser requirements

You need Google Chrome 25 or higher with working Native Client and OpenGL. Native Client is disabled by default and only apps from Chrome Web Store are allowed to run. This can be solved either by enabling Native Client in chrome://flags or running chrome from terminal with --enable-nacl option.

You can check that OpenGL is working on this native client example. It should display a cube which can be rotated using mouse. Some GPUs are blacklisted, you can try to bypass it with --disable-gpu-blacklist option.

How to play

Resume the game from menu. The cursor will be locked and you can use your mouse to look around and press up arrow or W key to move forward or push any box. If you screw something up, you can restart the level from the menu. When you successfully complete the level, next level will be loaded. There are currently 11 playable levels.

Why there is no...

Still work in progress :-)

Compiling and running the game

You can play the game online on the link provided above, but you can also compile and run it on your own. You can run it either natively using SDL2 or in NaCl itself. In case of NaCl you need these things:

  • Native Client SDK. Version used here is pepper_25, i.e. unzip it and run ./naclsdk update pepper_25.
  • CMake 2.8.8 or newer
  • Corrade, Magnum and Magnum Plugins compiled for NaCl and Corrade also compiled for your system (needed for resource compiler).

Get the toolchains submodule, if you don't have it already:

cd /path/to/push-the-box
git submodule init
git sumbodule update

Don't forget to adapt NACL_PREFIX variable in generic/NaCl-newlib-x86-32.cmake and generic/NaCl-newlib-x86-64.cmake to path where your SDK is installed, e.g. /home/johndoe/nacl_sdk/pepper_25. You may need to adapt also NACL_TOOLCHAIN_PATH so CMake is able to find the compiler.

Next create build directory for desired architecture (e.g. x86-64) and run CMake. The toolchains needs access to its platform file, so be sure to properly set absolute CMAKE_MODULE_PATH to toolchains/modules/ directory containing Platform/NaCl.cmake.

mkdir -p build-nacl-x86-64
cd build-nacl-x86-64
cmake .. \
    -DCMAKE_MODULE_PATH="/path/to/push-the-box/toolchains/modules" \
    -DCMAKE_TOOLCHAIN_FILE="../toolchains/generic/NaCl-newlib-x86-64.cmake" \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/path/to/webserver/directory
make

If you specified CMAKE_INSTALL_PREFIX, running make install will install the game with all additional files and libraries to given directory in your webserver and you can now run it from Chrome. Enjoy :-)
