Analisador de pacotes da Sala de jogos

Nesta página, mostramos como usar o analisador de pacotes da Sala de jogos.

Instruções

O analisador de pacotes da Sala de jogos pode ser executado em um pacote da Sala de jogos para realizar várias validações no pacote do jogo antes de fazer upload dos recursos no Google. Google Drive.

Pré-requisitos

• Instale o Python 3.

Criar o script

1. Identifique um diretório na sua máquina para criar o script (exemplo: ~/scripts).
2. Usando o exemplo de código fornecido, crie um arquivo na sua máquina chamada playables_bundle_analyzer.py.

Executar o script para analisar o pacote do jogo

1. Abra uma janela do terminal na sua máquina e navegue até o diretório. que contém o script playables_bundle_analyzer.py.

2. Execute este comando para executar o script, substituindo [GAME_DIRECTORY_PATH] pelo caminho real do diretório do pacote de jogos:

   python3 playables_bundle_analyzer.py [GAME_DIRECTORY_PATH]
   

3. Um relatório de análise de pacotes será gerado no diretório do script. Ele vai chamado playable_bundle_analysis_report.txt.

4. Consulte os Requisitos de estabilidade e desempenho para mais informações. sobre o requisito de tamanho de pacote e nomes de arquivo.
