List All Resource Types

Click here for the full example code.

We can access the metadata stored inside Bevy ECS to learn about the types of things currently stored.

This example shows how to print a list of all types that have been added as resources.

fn print_resources(archetypes: &Archetypes, components: &Components) {
    let mut r: Vec<String> = archetypes
        .map(|id| components.get_info(id).unwrap())
        // get_short_name removes the path information
        // i.e. `bevy_audio::audio::Audio` -> `Audio`
        // if you want to see the path info replace
        // `TypeRegistration::get_short_name` with `String::from`
        .map(|info| TypeRegistration::get_short_name(

    // sort list alphebetically
    r.iter().for_each(|name| println!("{}", name));

Note that this does not give you a comprehensive list of every Bevy-provided type that is useful as a resource. It lists the types of all the resources currently added to the app (by all registered plugins, your own, etc.).
