Standalone copy of the OpenBW replay viewer webpage (originally/normally hosted at http://www.openbw.com/replay-viewer).
Available on GitHub Pages at https://bmnielsen.github.io/openbw-replay-viewer.
This copy originated as a pure mirror of the OpenBW version, with all assets taken from an archived version of the OpenBW website on archive.org from January 16th 2024. The scripts for this version is still available in this repository under docs/v1.0.
After some fixes were made to OpenBW, the need arose to be able to build the actual OpenBW engine from source. At this point the build scripts were added with much assistance from tscmoo.
The website consists only of static HTML/JS/CSS, so there are many options to serve the assets locally. A Dockerized version based on nginx is included and can be run through ./serve.sh.
The OpenBW part of the website needs to be built using emscripten. A Dockerized build script is included and can be invoked through ./build_openbw.sh in the project root. It will run the emscripten build script in the Docker container and export the openbw.js and openbw.wasm files to the project root when it's done.
We are using an old version of emscripten (via its Docker image). tscmoo made an attempt to get it working on a new version of emscripten, but ran into some difficulties:
i think i figured out that the choppy audio i was having is due to it using an emscripten-built native version of sdl mixer, whereas the one you built uses SDL1 mixer (even though we ask for sdl 2), which emscripten has an implementation of built in javascript (so it uses the browser api to play audio, and doesn't need to feed the chunks with specific timing since the browser takes care of it)
this also gives worse performance - the native javascript api will always be faster than some native webassembly code
there supposedly is a way to use the sdl 1 library in the newest version of emscripten, too, and i've tried but keep getting various linker errors and such that i haven't figured out
the newer emscripten version also requires some small code changes
We will therefore stick with the old version of emscripten for the time being.
The OpenBW files are pulled in via a Git submodule. The other dependencies, SDL header files and dlmalloc, are included in this repo as they are also old versions to ensure interoperability with the version of emscripten being used.
