Minetest-wasm

This is an experimental port of Minetest to the web using emscripten/WebAssembly.

System Requirements

This has only been tested on Ubuntu 20.04.

Ubuntu: apt-get install -y build-essential cmake tclsh

Building

cd minetest-wasm
./build_all.sh

Installation

If the build completes successfully, the www/ directory will contain the entire application. This includes an .htaccess file which sets headers that are required (by browsers) to load the app. If your webserver does not recognize .htaccess files, you may need to set the headers in another way.

Network Play

By default, the proxy server is set to wss://minetest.dustlabs.io/proxy (see static/launcher.js). This is necessary for network play, since websites cannot open normal TCP/UDP sockets. This proxy is located in California. There are regional proxies which may perform better depending on your location:

North America (Dallas) - wss://na1.dustlabs.io/mtproxy South America (Sao Paulo) - wss://sa1.dustlabs.io/mtproxy Europe (Frankfurt) - wss://eu1.dustlabs.io/mtproxy Asia (Singapore) - wss://ap1.dustlabs.io/mtproxy Australia (Melbourne) - wss://ap2.dustlabs.io/mtproxy

You could also roll your own own custom proxy server. The client code is here:

Custom Emscripten

The Emscripten SDK (emsdk) will be downloaded and installed the first time you build. To provide your own instead, set $EMSDK before building (e.g. using emsdk_env.sh). An external Emscripten may need to be patched by running this exactly once:

./apply_patches.sh /path/to/emsdk
