Race condition on multiple similar AssetLoaders

[Kaendor]

Hello,

I am currently trying to apply clean asset loading to two of my Plugin.

As per the guide, I am initializing a loopless_state with app.add_loopless_state(GameState::Loading) before using any of my plugins.

I am doing the following :

In MeteorPlugin :

AssetLoader::new(GameState::Loading)
            .continue_to_state(GameState::Level)
            .with_collection::<MeteorAssets>()
            .build(app);

app.add_enter_system(GameState::Level, spawn_asteroid_field);

In ShipPlugin :

 AssetLoader::new(GameState::Loading)
            .continue_to_state(GameState::Level)
            .with_collection::<LoadingShipAssets>()
            .build(app);

app.add_enter_system(GameState::Level, setup_spaceship_system)

When I was using the AssetLoader in only one Plugin everything went fine. But as soon as I added asset collection loading to the other, I believe the GameState::Level was entered too soon and made my code panic since all the assets were not loaded yet.

It kinda looks like a race condition between each AssetLoader.

I thought when declaring more than one AssetLoader on a given state, it would aggregate all the collections needed, wait for all of them to load, and then transition to the given state.

Thank you for your time!

Thank you for raising the issue. This should work, but I can reproduce, that it currently does not.

I'll fix it
