Editing Rizline:Assets

'''Assets''' are [[Rizline:game files|game files]] that are downloaded on-demand. These assets can be updated at any time by ''Rizline''<nowiki>'</nowiki>s developers, and they do not need an app update to be modified.

== How the game checks for asset updates ==

Every time ''Rizline'' is launched, it sends a GET request to download the [[Rizline:game_config.json|game_config.json]] file. It then finds a resource URL for the current app version, and uses it to download the [[Rizline:catalog_catalog.json|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 The game then checks for missing or outdated asset bundles, and downloads only the updated or missing ones from the servers.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 ==

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:
* [[Rizline:Song music|Song music]] - downloaded when selecting a specific song (tapping a song bubble) on the [[Rizline:Song Select screen|Song Select screen]].
* [[Rizline:Chart|Chart files]] - downloaded when playing a specific chart for the first time (only the played difficulty is downloaded).
* High-quality versions of [[Rizline:illustration|illustration]]s (2048px × 2048px, instead of the usual 512px × 512px) - downloaded when zooming in on a specific illustration in the [[Rizline:gallery|gallery]].
* High-quality versions of [[Rizline:Rizcard|Rizcards]] (2048px × 2048px, instead of the usual 512px × 512px) - downloaded when zooming in on a specific Rizcard in the [[Rizline:gallery|gallery]].
