Resources

We’re starting to get quite a lot of code in our main function so it’s time to refactor again to improve the code structure a little.

We’ll start by moving all the loading of file assets to a struct. At the same time we will change all the unwrap() and expect() calls to using the ? operator to handle error messages.

After that we will make use of a coroutine to load the resources in the background while also displaying a message about loading resources on the screen.

Finally we will use a Storage struct to make the resources available in the code without having to send them around to every function where they are needed.
