LibGDX静态AssetManager

Question

I am having some trouble figuring out the proper use of libGDX's AssetManager class. From what I understand, you are never supposed to create a static instance of an AssetManager. The alternative that people suggested was to pass around the AssetManager reference to every single class that uses it. I'm wondering if what I have proposed below is another safe alternative.

public class GdxGame extends Game {

    private AssetManager assets;

    ....dispose, create AssetManager etc


    public static AssetManager getAssets() {
        return ((GdxGame) Gdx.app.getApplicationListener()).assets;
    }
}

I really don't want to have to pass an AssetManager or an Assets class around to every single class in the game, so I'm trying to figure out a solution that allows some kind of static referencing. Is this safe?

Answer 1

I think you worry too much :-) The static instance you suggested originally will be perfectly adequate and functional for your purposes:

private static AssetManager assets;
....dispose, create AssetManager etc

public static AssetManager getAssets() {
    return assets;
}

The only trap for young players to avoid is when you pause an Android app: on resume, just reload the AssetManager and its assets before continuing. Don't worry about semantics - if it works for you, then it's fine. Happy days :-).
