DOOM plugin for Figma
I have been wanting to do a Figma plugin since the support for it was announced, and since i like the product so much, so when i saw that someone tweeted How soon until someone ports original DOOM to Figma it felt like the right combination of useless, stupid and interesting enough.
How does it work
So i looked for a WebAssembly doom port and found this one tried to build it, had to patch a couple of things because i was using a more recent version of Emscripten.
I tried running webassembly directly in the plugin but thanks to the security boundaries in Figma the plugin was unable to fetch the data needed, so i had to resort to an <IFRAME> instead and host the actual game somewhere else.
Using it
Download this and unpack it somewhere, select "Link existing plugin" in the "Create plugin" dialog, then select the plugin/manifest.json file.
Building it yourself
The plugin itself is very simple, it is just an iframe, to change where it loads the game from, change the server URL in code.js in the plugin folder.
The server part needs to be hosted on HTTPS, so either deploy it somewhere or just use ngrok or a similar service to tunnel your local machine.
The WebAssembly Doom port itself requires Emscripten to build, you also need to download the shareware IWAD file.
I had to patch a few things to make it build, they're in the doom/patch.diff file, apply them like this patch -p1 < path/to/doom/patch.diff
After bootstrapping Emscripten you can use cmake to build it.
mkdir build
cd build
emconfigure cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
This will produce a doom.js, doom.wasm, doom.data and a doom.html - put all but the html file into the server folder
