Analyseur de bundle intégrés

Cette page explique comment utiliser l'analyseur de jeux intégrés.

Instructions

L'analyseur de jeux intégrés peut être exécuté sur un lot de jeux intégrés pour effectuer plusieurs validations sur le pack de jeu avant d'importer les assets sur Google Drive.

Prérequis

Créer le script

  1. Identifiez un répertoire sur votre machine pour créer le script (exemple: ~/scripts).
  2. À l'aide de l'exemple de code fourni, créez un fichier sur votre machine. appelé playables_bundle_analyzer.py.

Exécuter le script pour analyser le pack de jeu

  1. Ouvrez une fenêtre de terminal sur votre machine et accédez au répertoire contenant le script playables_bundle_analyzer.py.

  2. Exécutez le script en exécutant la commande suivante, en remplaçant [GAME_DIRECTORY_PATH] par le chemin d'accès réel au répertoire de votre pack de jeux:

    python3 playables_bundle_analyzer.py [GAME_DIRECTORY_PATH]

  3. Un rapport d'analyse du groupe sera généré dans le répertoire du script. Il va être nommée playable_bundle_analysis_report.txt.

  4. Pour en savoir plus, consultez les exigences de stabilité et de performances. sur la taille du bundle et les exigences liées aux noms de fichiers.
