# Exporta o Jump & Sword & Dash (Antonio Montes "Garydos", 2019; codigo MIT, imagens e sons CC0, arte de Kenney
# 1-Bit Pack CC0, github.com/Garydos/jump-sword-dash) para a web com o Godot 3.5.3 oficial: modelo
# webassembly_release (sem threads: nao precisa de SharedArrayBuffer nem de COOP/COEP), sem PWA. O repositorio
# traz um export_presets.cfg que nao serve para a nossa pagina; o nosso fica ao lado deste script. Mudancas no
# projeto, todas feitas aqui (o fonte publicado ja as traz):
#   - saem Layer_0000_9.png e Layer_0002_7.png (fundo parallax de Eder Muniz, CC BY-ND, que o README do autor
#     separa das imagens CC0) e as texturas dos dois Sprite do ParallaxBackground (os nos ficam, os scripts do
#     jogo os acessam); sai tambem background.png (fundo do menu, recorte da mesma floresta de Eder Muniz) e
#     a linha "Backgrounds: Eder Muniz" do menu, e wea0013690311.jpg (foto de arco-iris da tela de abertura,
#     de origem nao declarada; o no Sprite fica sem textura);
#   - a fonte Fipps (licenca desconhecida) vira Press Start 2P (SIL OFL 1.1, google/fonts no commit pinado,
#     conferida pelo SHA-256), com o OFL.txt ao lado;
#   - sai a pasta .import/ (cache do editor commitado pelo autor; o Godot a refaz com os mesmos nomes).
#
#   src/FredGames.Bundler/Builds/build-jump-sword-dash.sh
#
# O editor (macOS) e os modelos de exportacao vem do release 3.5.3-stable do GitHub, conferidos pelo SHA-256
# e ficam em artifacts/tools/godot-3.5.3, instalados sob lockf (outros scripts podem estar instalando ao
# mesmo tempo). O editor roda com HOME dentro da pasta de saida (configuracao e modelo isolados).
#
# Saida: artifacts/build/jump-sword-dash-6cf8ffe/{web/,jump-sword-dash-6cf8ffe.tar.gz}, que o bundle.yaml do
# jogo confere pelo SHA-256. O tar.gz e o fonte publicado (o projeto no commit pinado ja com as mudancas
# acima) e sai igual a cada execucao.
