# Exporta o Strange Winds (Yuri N. Martinez Laskowski e Lui Wolff, OpenGameArt Winter Game Jam 2022; GPL-3.0)
# para a web com o Godot 3.5.3 oficial: modelo webassembly_release (sem threads), sem PWA. O repositorio traz
# um export_presets.cfg so para desktop; o nosso (preset "Web") fica ao lado deste script. Mudancas no projeto,
# todas feitas aqui (e entregues no tar do fonte, que e o projeto ja mudado):
#   1. gfx/gui/navigator_portrait.png (retrato animado do navegador, do pacote "Animated Shadowy Portraits" de
#      YuriNikolai) e rostos gerados por StyleGAN2, e a OpenGameArt tirou os arquivos do ar por "possiveis
#      problemas de licenca". Como a licenca nao esta comprovada, trocamos por uma silhueta desenhada por nos
#      (scripts/navigator_silhouette.py, GPL-3.0-or-later) e tiramos o credito de texts/credits.csv e README.md.
#   2. Os botoes Quit (menu, tela de morte, tela final) nao fazem sentido numa pagina web: o do menu nao faz
#      nada e os outros voltam ao menu.
#
#   src/FredGames.Bundler/Builds/build-strange-winds.sh

# Saida: artifacts/build/strange-winds-9b50080/{web/,strange-winds-9b50080.tar.gz}, que o bundle.yaml do jogo
# confere pelo SHA-256. O tar.gz e o projeto do commit com as mudancas acima (fonte GPL), deterministico.
