# Compila o Scorch (artilharia por turnos de Volodymyr Shcherbinin, MIT; Rust + macroquad 0.4.16) em WebAssembly a partir do
# commit 2fda9ff de github.com/vovinacci/scorch-game: cargo build --release --locked --no-default-features (sem o
# auto-update) --target wasm32-unknown-unknown (Cargo.lock do autor mais o patch, Rust 1.92.0 de artifacts/tools). Os sons
# sao sintetizados em tempo de execucao e a fonte (ScorchMono, OFL) entra no .wasm; nao ha arquivos de dados.
#
# Mudancas (scorch/scorch-wasm.patch): saves em localStorage (quad-storage, chaves "scorch.run.json" e "scorch.profile.json") em
# vez de arquivos; sem sys-locale/dirs no navegador (idioma inicial = ingles); sem o gancho de relatorio de crash (grava arquivo
# e usa SystemTime); o item "Quit" do menu some e "salvar e sair" volta ao menu. Cargo.lock acompanha o patch.
# A pagina (scorch/index.html) e nossa; mq_js_bundle.js e o do crate macroquad 0.4.16 (a pagina declara a global register_plugin, que o bundle atribui sem
# declarar), sapp_jsutils.js o do sapp-jsutils 0.1.5 (o quad-storage.js usa o js_object global dele) e quad-storage.js o do commit a359374 de optozorax/quad-storage (plugin 0.1.2, o do quad-storage-sys 0.1.0).
#
#   src/FredGames.Bundler/Builds/build-scorch.sh
#
# Saida: artifacts/build/scorch-2fda9ff/{scorch-2fda9ff-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
