Bevy Web Asset

This is a tiny crate that that wraps the standard bevy asset loader, and adds the ability to load assets from http and https urls.

Supports both wasm (web-sys) and native.

If asset paths start with http:// or https://, then we try to do a web request to load the asset, otherwise, we just call the normal asset io.

This is nice if you want to keep your content on a server, even when developing native games. Use cases can be:

• Tuning game balance post-launch
• Seasonal events (halloween theme etc.)
• Downloading dynamic content from 3rd party services (lospec, gltf repositories etc.)
• Sharing user-created assets/mods over some service (level editor etc.)
• Keeping initial download size small
• Testing with different online assets during development

Usage

NOTE: You need to add the plugin before DefaultPlugins:

App::new()
    // The web asset plugin must be inserted before the `AssetPlugin` so
    // that the asset plugin doesn't create another instance of an asset
    // server. In general, the AssetPlugin should still run so that other
    // aspects of the asset system are initialized correctly.
    .add_plugin(WebAssetPlugin)
    .add_plugins(DefaultPlugins)
    .add_startup_system(setup)
    .run();
});

But using it is quite simple, just use http urls instead of regular asset paths.

let font: Handle<Font> = asset_server.load("https://example.com/fonts/quicksand-light.ttf");

Or:

commands.spawn_bundle(SpriteBundle {
    // Simply use a url where you would normally use an asset folder relative path
    texture: asset_server.load("https://johanhelsing.studio/assets/favicon.png"),
    ..default()
});

Bevy version support

I intend to support the latest bevy release in the main branch.

Fixes against the Bevy main branch goes in the the bevy-main branch and are merged back into main whenever bevy is released.
