This means that pressing Refresh button and adding servers manually now uses TCP. The master-server and initial scan are still UDP as they will be replaced by Game Coordinator; no need to change this now. If we query a server that is too old, show a proper warning to the user informing him the server is too old.
How to build with Emscripten
Building with Emscripten works with emsdk 2.0.10 and above.
Currently there is no LibLZMA support upstream; for this we suggest to apply the provided patch in this folder to your emsdk installation.
For convenience, a Dockerfile is supplied that does this patches for you against upstream emsdk docker. Best way to use it:
Build the docker image:
docker build -t emsdk-lzma .
Build the host tools first:
mkdir build-host
docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build-host emsdk-lzma cmake .. -DOPTION_TOOLS_ONLY=ON
docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build-host emsdk-lzma make -j5 tools
Next, build the game with emscripten:
mkdir build
docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build emsdk-lzma emcmake cmake .. -DHOST_BINARY_DIR=$(pwd)/build-host -DCMAKE_BUILD_TYPE=RelWithDebInfo -DOPTION_USE_ASSERTS=OFF
docker run -it --rm -v $(pwd):$(pwd) -u $(id -u):$(id -g) --workdir $(pwd)/build emsdk-lzma emmake make -j5
And now you have in your build folder files like "openttd.html".
To run it locally, you would have to start a local webserver, like:
cd build
python3 -m http.server
Now you can play the game via http://127.0.0.1:8000/openttd.html .
