# Compila o Asteroid Capitalist (nave espacial, tiros com o mouse, Open Jam 2019, de Sidaroth e Garlov, MIT; Phaser 3 + matter-js) a partir
# do commit f86d05e de github.com/Sidaroth/Asteroid.Capitalist. O projeto do autor usa webpack 4 + node-sass 4, que nao rodam no Node 24:
# aqui o esbuild 0.28.1 junta o codigo com as mesmas bibliotecas nas versoes do package-lock.json do autor (phaser 3.24.1, matter-js 0.14.2,
# immutable 3.8.2; fixadas por asteroid-capitalist/package-lock.json, "npm ci"), usando o phaser/dist/phaser.min.js oficial do pacote, com
# os mesmos apelidos de caminho do webpack (configs, core, scenes...). A folha de estilo SCSS do autor so usa CSS comum.
#
# Mudancas (asteroid-capitalist/asteroid-capitalist-fredygames.patch): sem o painel de desenvolvimento dat.gui e o medidor stats-js (so rodavam com
# DEBUG ligado; o patch tira os imports de UI.js, e o bundle nao os traz); resizeCanvas.js avisa o Phaser do novo tamanho do canvas (sem isso o Play nao recebe cliques com a janela menor que 1920x1080); index.html proprio, com CSP que bloqueia qualquer requisicao externa
# (o do autor vem de um template do html-webpack-plugin) e main.css no lugar do main.scss. As pastas assets/ (imagens, audio e fontes) vao como estao,
# sem os projetos do TexturePacker (.tps).
#
#   src/FredGames.Bundler/Builds/build-asteroid-capitalist.sh
#
# Saida: artifacts/build/asteroid-capitalist-f86d05e/{asteroid-capitalist-f86d05e-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
