Module prelude

Expand description

The asset prelude.

This includes the most common types in this crate, re-exported for your convenience.

Structs§

AssetChanged: Filter that selects entities with an A for an asset that changed after the system last ran, where A is a component that implements AsAssetId.
AssetPlugin: Provides “asset” loading and processing functionality. An Asset is a “runtime value” that is loaded from an AssetSource, which can be something like a filesystem, a network, etc.
AssetServer: Loads and tracks the state of Asset values from a configured AssetReader. This can be used to kick off new asset loads and retrieve their current load states.
Assets: Stores Asset values identified by their AssetId.

AssetEvent: Messages that occur for a specific loaded Asset, such as “value changed” events and “dependency” events.
AssetId: A unique runtime-only identifier for an Asset. This is cheap to Copy/Clone and is not directly tied to the lifetime of the Asset. This means it can point to an Asset that no longer exists.
AssetMode: Controls whether or not assets are pre-processed before being loaded.
Handle: A handle to a specific Asset of type A. Handles act as abstract “references” to assets, whose data are stored in the Assets<A> resource, avoiding the need to store multiple copies of the same data.
UntypedHandle: An untyped variant of Handle, which internally stores the Asset type information at runtime as a TypeId instead of encoding it in the compile-time type. This allows handles across Asset types to be stored together and compared.

Asset: Declares that this type is an asset, which can be loaded and managed by the AssetServer and stored in Assets collections.
AssetApp: Adds asset-related builder methods to App.
DirectAssetAccessExt: An extension trait for methods for working with assets directly from a World.
