A simple falling sand simulation written in C and compiled to WebAssembly. This can be used as a new tab page in Google Chrome or Firefox.
Press almost any key to make sand randomly fall from the top of the screen. When escape or backspace are pressed, around half of the sand will disappear. When the window is resized, the sand will adjust to match the new size.
Download "dist-chrome.zip" from the latest release and unzip the file. Go to "chrome://extensions", turn on "Developer mode", and click "Load unpacked". Then select the unzipped directory.
Download "dist-firefox.zip" from the latest release. The requirement for signed add-ons needs to be turned off in order to allow this add-on to persist. To do this, go to "about:config", and set xpinstall.signatures.required to false. Finally, go to "about:addons" and drag the zip file into the page.
Open the "index.html" file from any distribution directory. Note that this will need to be done using a server due to CORS policy (for example, run python3 -m http.server).
Requirements:
- Emscripten is needed in order to compile the project to WebAssembly. Install by following the instructions here.
jqis needed to create the correct manifest files for different browsers. Install from here.
After installing the required programs, run make to build the extension/add-on. This will output both a "dist-firefox.zip" and a "dist-chrome.zip" which can be used in the respective browsers.
If you are editing any of the C files, it may be helpful to have a "compile_flags.txt" so your language tools work correctly. This can be generated by running make compile_flags.txt.
