Mini Game Subpackage

Some mini game platforms support subpackaging to divide resources, scenes, and scripts. Creator supports Asset Bundle starting in v2.4, which allows developers to divide contents that need to be subpackaged into multiple Asset Bundles, and these Asset Bundles will be built into subpackages of the mini game. Only the necessary main packages will be downloaded when you startup the game, and these subpackages will not be loaded, but will be manually loaded by the developer during the game. This effectively reduces the time for the game startup.

Configuration

The Asset Bundle is configured in folders. When we select a folder in the Assets panel, the Properties panel will show a Is Bundle option, if set, the folder-related configuration options will appear:

In addition to the general Asset Bundle Configuration, the main settings to focus on for the mini game subpackages are:

• Set the Target Platform to the mini game platform that you want to subpackage, and set the Compression Type to the Mini Game Subpackage.
• The mini game subpackages can only be placed locally and cannot be configured as remote packages, so the Is Remote Bundle option cannot be checked.

Once configured, click the Apply button at the top right and the folder will be configured as a Asset Bundle.

Build

After the project is built, this Asset Bundle folder is packaged into the subpackages folder in the release package directory of the mini game platform. Each folder contained in this folder is an Asset Bundle.

For example, if the cases/01_graphics folder in the example-case is configured as an Asset Bundle on the WeChat Mini Game, then after the project is built, a 01_graphics folder is generated in the subpackages folder in the release package directory, and the 01_graphics folder is an Asset Bundle.

WeChat Mini Games
