Rizline:Assets
Assets are game files that are downloaded on-demand. These assets can be updated at any time by Rizline's developers, and they do not need an app update to be modified.
How the game checks for asset updates
[edit | edit source]Every time Rizline is launched, it sends a GET request to download the game_config.json file. It then finds a resource URL for the current app version, and uses it to download the catalog_catalog.json file, which contains a list of all of the names of the asset bundles that the game uses. The game then checks for missing or outdated asset bundles, and downloads only the updated or missing ones from the servers.
If an old asset bundle is updated, the previous version is overwritten by the new one, effectively deleting it from the device. However, if an old asset bundle goes unused, it stays on the device until the user deletes the app data or uninstalls the application.
Assets downloaded on-demand
[edit | edit source]Some assets are required for the game to work and are downloaded at start-up, while others are not required immediately and are downloaded when needed. Examples of assets downloaded on-demand include:
- Song music - downloaded when selecting a specific song (tapping a song bubble) on the Song Select screen.
- Chart files - downloaded when playing a specific chart for the first time (only the played difficulty is downloaded).
- High-quality versions of illustrations (2048px × 2048px, instead of the usual 512px × 512px) - downloaded when zooming in on a specific illustration in the gallery.
- High-quality versions of Rizcards (2048px × 2048px, instead of the usual 512px × 512px) - downloaded when zooming in on a specific Rizcard in the gallery.
