- Event Occurs:
- Asteroid explodes.
- It shouts into the SignalBus: "I died! Here is my point value (100)."
- Logic Handles It:
- ScoreManager (or GameManager) hears the shout.
- It adds 100 to total_score.
- It shouts back into the SignalBus: "The score is now 500."
- UI Displays It:
- HUD hears "Score is 500" and updates the text.
