Penganalisis paket Ruang Game

Halaman ini membahas cara menggunakan penganalisis paket Ruang Game.

Petunjuk

Penganalisis paket Ruang Game dapat dijalankan di paket game Ruang Game untuk menjalankan beberapa validasi pada paket game sebelum mengupload aset di Google Mengemudi.

Prasyarat

• Instal Python 3.

Membuat skrip

1. Identifikasi direktori di komputer Anda untuk membuat skrip (contoh: ~/scripts).
2. Buat file di mesin Anda menggunakan kode contoh yang diberikan disebut playables_bundle_analyzer.py.

Menjalankan skrip untuk menganalisis paket game

1. Buka jendela terminal pada komputer Anda dan arahkan ke direktori yang berisi skrip playables_bundle_analyzer.py.

2. Jalankan skrip dengan menjalankan perintah ini, dengan mengganti [GAME_DIRECTORY_PATH] dengan jalur sebenarnya dari direktori paket game Anda:

   python3 playables_bundle_analyzer.py [GAME_DIRECTORY_PATH]
   

3. Laporan analisis paket akan dibuat di direktori skrip. Materi ini akan diberi nama playable_bundle_analysis_report.txt.

4. Lihat Persyaratan stabilitas dan performa untuk informasi selengkapnya tentang ukuran paket dan persyaratan nama file.
