Question on Managing Points In the Asteroid Example

[Chad Stever]

I am playing around with the Asteroid example by implementing a UI to show lives and points, and I have a question on best practices for implementing this feature.  I have looked at the other topics and created my HUD outside of the game and implemented an Event Bus that I pass into the game.  For lives, the game manager dispatches an event and the HUD picks it up and that seems like the best for that.

if (clearToAddSpaceship)

{

eventBus.dispatch( EventBus.LIVES_EVENT, new LifeEvent(node.state.lives) );

        creator.createSpaceship();

        node.state.lives--;

}

For the points, however, I am not sure I am doing it the best way.  I modified the collision system to be aware of GameNodes.  When ever an asteroid is destroyed I update the GameNode. Then the GameManager dispatches an event for the HUD to pick up.

Is there a better way of doing this?
