# Exporta o Freaky Towers (Vyacheslav "Slava0135" Kovalevsky, 2023; MIT, github.com/Slava0135/Freaky-Towers)
# para a web com o Godot 4.4.1 oficial (o projeto e do 4.1; o editor 4.4 o reimporta sem mudar o jogo):
# renderer Compatibility, SEM threads (modelo web_nothreads_release: nao precisa de SharedArrayBuffer nem dos
# cabecalhos COOP/COEP), sem PWA. O repositorio traz um export_presets.cfg de desktop; o nosso (preset "Web")
# fica ao lado deste script e inclui o attributions.md, que a tela de creditos do jogo le.
# Mudancas no projeto, todas feitas aqui e visiveis no fonte publicado:
#  - backgrounds/night.jpg (foto do Unsplash, de Talha Imam) e trocado por um fundo nosso, gerado por
#    freaky-towers/make-night.py (ceu noturno com estrelas e lua, dedicado ao dominio publico, CC0 1.0), e
#    o attributions.md deixa de citar a foto e cita o fundo novo;
#  - o botao "Report Bug" do menu (LinkButton para o GitHub do autor, que abriria outro site) sai;
#  - o jogo roda como o autor publicou em todo o resto.
#
#   src/FredGames.Bundler/Builds/build-freaky-towers.sh
#
# O editor (macOS universal) e os modelos de exportacao vem do release 4.4.1-stable do GitHub, conferidos pelo
# SHA-256 e ficam em artifacts/tools/godot-4.4.1, instalados sob lockf. O editor roda com HOME dentro da pasta
# de saida (configuracao e modelo isolados).
#
# Saida: artifacts/build/freaky-towers-8f4fe16/{web/,freaky-towers-8f4fe16.tar.gz}, que o bundle.yaml do jogo
# confere pelo SHA-256. O tar.gz e o fonte do jogo ja com o fundo novo e sai igual a cada execucao.
