flappy_bird | Flappy Bird written in Ruby with Ruby | Game Engine library

I've 3 class loaders:

1. MainLoader
2. PreloadingLoader
3. GameSceneLoader

There's only one instance of MainLoader throughout execution of a program, but PreloadingLoader and GameSceneLoader can be recreated on demand.

When I load any class in my program, I want to:

• if the class name begins with any of staticClasses load it with MainLoader
• if the class name begins with any of preloadingClasses load it with PreloadingLoader
• if the class name beings with pl.gieted.flappy_bird but isn't listed on neither of above lists, load it with GameSceneLoader
• otherwise load it with a default class loader

This below code works, but only for the first class loaded, e.g:

1. pl.gieted.flappy_bird.engine.Renderer is requested by GameSceneLoader
2. MainLoader tries to load it, because it's the oldest parent of GameSceneLoader
3. The Renderer has a class dependency of LoadingScene
4. Since Renderer was loaded using MainLoader, the Loading Scene is also being loaded using MainLoader, however it can't find it.
5. java.lang.NoClassDefFoundError is thrown.

What I want to happen instead is:

1. pl.gieted.flappy_bird.engine.Renderer is requested by GameSceneLoader
2. MainLoader tries to load it, because it's the oldest parent of GameSceneLoader
3. The Renderer has a class dependency of LoadingScene
4. Loading of LoadingScene is passed back to GameSceneLoader
5. MainLoader cannot find it.
6. PreloadingLoader finds it and loads it
7. Loading continues...
