Bevy common assets

crates.io docs license crates.io

Collection of Bevy plugins offering generic asset loaders for common file formats.

Supported formats:

format feature example
json json json.rs
msgpack msgpack msgpack.rs
postcard postcard postcard.rs
ron ron ron.rs
toml toml toml.rs
xml xml xml.rs
yaml yaml yaml.rs
csv csv csv.rs

Usage

Enable the feature(s) for the format(s) that you want to use.

Define the types that you would like to load from files and derive serde::Deserialize, bevy::reflect::TypePath, and bevy::asset::Asset for them.

#[derive(serde::Deserialize, bevy::asset::Asset, bevy::reflect::TypePath)]
struct Level {
    positions: Vec<[f32;3]>,
}

With the types ready, you can start adding asset plugins. Every plugin gets the asset type that it is supposed to load as a generic parameter. You can also configure custom file endings for each plugin:

use bevy::prelude::*;
use bevy_common_assets::json::JsonAssetPlugin;
use bevy_common_assets::msgpack::MsgPackAssetPlugin;
use bevy_common_assets::postcard::PostcardAssetPlugin;
use bevy_common_assets::ron::RonAssetPlugin;
use bevy_common_assets::toml::TomlAssetPlugin;
use bevy_common_assets::xml::XmlAssetPlugin;
use bevy_common_assets::yaml::YamlAssetPlugin;

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins,
            JsonAssetPlugin::<Level>::new(&["level.json", "custom.json"]),
            RonAssetPlugin::<Level>::new(&["level.ron"]),
            MsgPackAssetPlugin::<Level>::new(&["level.msgpack"]),
            PostcardAssetPlugin::<Level>::new(&["level.postcard"]),
            TomlAssetPlugin::<Level>::new(&["level.toml"]),
            XmlAssetPlugin::<Level>::new(&["level.xml"]),
            YamlAssetPlugin::<Level>::new(&["level.yaml"])
        ))
        // ...
        .run();
}

#[derive(serde::Deserialize, bevy::asset::Asset, bevy::reflect::TypePath)]
struct Level {
    positions: Vec<[f32; 3]>,
}

The example above will load Level structs from json files ending on .level.json or .custom.json, from ron files ending on .level.ron and so on...

See the examples for working Bevy apps using the different formats.
