Spawning scripts

To spawn a Ruby script you will need to get a handle to a script asset using bevy's AssetServer.

# extern crate bevy;
# extern crate bevy_scriptum;

use bevy::prelude::*;
use bevy_scriptum::prelude::*;
use bevy_scriptum::runtimes::ruby::prelude::*;

fn my_spawner(mut commands: Commands, assets_server: Res<AssetServer>) {
    commands.spawn(Script::<RubyScript>::new(
        assets_server.load("my_script.rb"),
    ));
}

After they scripts have been evaled by bevy_scriptum, the entities that they've been attached to will get the Script::<RubyScript> component stripped and instead RubyScriptData component will be attached.

So to query scipted entities you could do something like:

# extern crate bevy;
# extern crate bevy_scriptum;

use bevy::prelude::*;
use bevy_scriptum::prelude::*;
use bevy_scriptum::runtimes::ruby::prelude::*;

fn my_system(
    mut scripted_entities: Query<(Entity, &mut RubyScriptData)>,
) {
    for (entity, mut script_data) in &mut scripted_entities {
        // do something with scripted entities
    }
}
