#Milky2018/selene_raylib

Native backend implementation for Selene based on tonyfettes/raylib.

#Embed assets with MoonBit pre-build

This is an optional optimization and packaging workflow for native binary distribution. By default, you can skip it and let raylib load textures/audio/fonts from the filesystem.

#1. Install the asset bundling CLI

moon install Milky2018/selene_tools/cmd/selene-embed-assets

#2. Add pre-build hooks in your game package moon.pkg

options(
  "pre-build": [
    {
      "input": "<assets-dir>",
      "output": "_embedded_assets.pack",
      "command": "selene-embed-assets --assets-dir $input --pack-out $output --path-prefix <runtime-prefix>",
    },
    {
      "input": "<assets-dir>",
      "output": "embedded_assets_index.mbt",
      "command": "selene-embed-assets --assets-dir $input --index-out $output --path-prefix <runtime-prefix> --blob-name embedded_assets_blob --lookup-fn get_embedded_asset",
    },
    {
      "input": "_embedded_assets.pack",
      "output": "embedded_assets_blob.mbt",
      "command": ":embed --binary -i $input -o $output --name embedded_assets_blob",
    },
  ],
)

Use the same <assets-dir> in both pre-build steps, and set <runtime-prefix> to match your runtime asset paths.

This generates:

embedded_assets_blob.mbt (raw bytes via :embed)
embedded_assets_index.mbt (get_embedded_asset(path) -> Bytes?)

#3. Install embedded lookup before App::run (only when embedding is enabled)

import { "Milky2018/selene/asset" @asset }

fn main {
  @asset.set_io(get_embedded_asset)
  // app.run()
}

When installed, selene_raylib will prefer embedded bytes for:

images/textures
sounds/music
fonts

If a path is not found in embedded assets, it falls back to filesystem loading.

If embedding is not enabled, you should not call set_io.
