Hi, first time using a DI framework and I want to know if these bindings are structured correctly.

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Without seeing the actual code, it is difficult to provide a specific review. However, I can give you some general guidance on using Guice with libgdx.

  1. Make sure you have the necessary dependencies: To use Guice with libgdx, you need to include the appropriate Guice and libgdx dependencies in your project's build file (e.g., Maven or Gradle).

  2. Create a module: In Guice, bindings are defined in modules. You should create a module class where you define all your bindings. This class should extend com.google.inject.AbstractModule.

  3. Bind your classes: Inside your module class, use the bind() method to bind your classes/interfaces to their implementations. For example:

#
public class MyModule extends AbstractModule {
    @Override
    protected void configure() {
        bind(MyInterface.class).to(MyImplementation.class);
        // other bindings...
    }
}
#
  1. Install your module: In your application's entry point (e.g., Main class), create an instance of your module and install it in the com.google.inject.Guice.createInjector() method:
#
public class Main {
    public static void main(String[] args) {
        Injector injector = Guice.createInjector(new MyModule());
        // other initialization code...
    }
}
#
  1. Inject dependencies: Now you can use dependency injection by annotating fields or constructor parameters with @Inject:
#
public class MyClass {
    private final MyInterface myInterface;

    @Inject
    public MyClass(MyInterface myInterface) {
        this.myInterface = myInterface;
    }

    // ...
}
#
  1. Use dependency injection in libgdx components: If you want to use dependency injection in libgdx components like ApplicationListener, you can create a custom Game subclass and inject dependencies into it:
#
public class MyGame extends Game {
    @Inject
    private MyInterface myInterface;

    @Override
    public void create() {
        Injector injector = Guice.createInjector(new MyModule());
        injector.injectMembers(this);
        // other initialization code...
    }

    // ...
}
#

These are the general steps to use Guice with libgdx. Make sure to review the Guice documentation for more details and best practices.
