# Exporta o Godot Open RPG (GDQuest, demo de RPG por turnos; codigo e arte do projeto MIT, arte, musica e sons de
# terceiros CC0 listados no CREDITS.md, addon Dialogic MIT, github.com/gdquest-demos/godot-open-rpg) para a web
# com o Godot 4.7.2 oficial (a versao que o projeto pede): renderer Compatibility, SEM threads (modelo
# web_nothreads_release), sem PWA. O export_presets.cfg e nosso, ao lado deste script. Uma mudanca no projeto,
# feita aqui: dos "Example Assets" que o Dialogic traz (retratos, fundos, fontes Roboto, etc., de varios autores
# e licencas), ficam so os sons de digitacao (CC BY-SA 4.0, usados pelo jogo, com o LICENSE.txt deles) e o
# next-indicator.png (referenciado pelo codigo do addon); o resto sai.
#
# ATENCAO: este export NAO e bit a bit reprodutivel. O Godot 4 sorteia um unique_id novo para os nos de cada
# cena que converte para binario (export-*.scn em .godot/exported/), entao index.pck muda a cada execucao; o
# resto (wasm, js, icones, o tar.gz do fonte) e identico. O bundle.yaml pina a saida gerada por ultimo; rodar o
# script de novo exige atualizar o sha256 do index.pck (e do index.html, que traz o tamanho dele).
#
#   src/FredGames.Bundler/Builds/build-godot-open-rpg.sh
#
# O editor (macOS) e os modelos de exportacao vem do release 4.7.2-stable do GitHub, conferidos pelo SHA-256
# e ficam em artifacts/tools/godot-4.7.2, 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/godot-open-rpg-d59f2f7/{web/,godot-open-rpg-d59f2f7.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.
