This is the build environment for RenPyWeb.

• See https://github.com/renpy/renpy-build/ - something like:

  git clone https://github.com/renpy/renpy-build/
  cd renpy-build/
  BASE=. bash ./nightly/git.sh
  # fix-up tasks ordering
  ./build.py --platform web
  

• Emscripten: you need to recompile everything on upgrade:

  rm -rf build/ install/ python-emscripten/2.7.18/build/
  make cythonclean
  emcc --clear-ports
  

• Recompile:

  make
  scripts/install_in_renpy.sh
  

• Package the game: from the Ren'Py interface, or using scripts/distribute_game.sh (basic testing only)

  make testserver
  $BROWSER http://localhost:8000/

Check the pygame-example-* targets. Symlink pygame-example/main.py to the variant you wish to experiment with.

Also check the native target to try to run Ren'Py natively with some Emscripten behavior.
