[alaindet]

• Conceptualize a queue containing game actions
• The game actions queue can resolve with a delay (for animations), or immediately
• The queue should an API so that
  • You can add actions with a delay (for animations)
  • You can add immediate actions
  • You can both add delayed and immediate actions immediately on the queue or trigger them as soon as the queue stabilizes (animations are finished)
• While resolving a game action with a delay, debounce any game action
• It is important to debounce and not just thottle game actions since the player could potentially flood the queue with game actions coming from the keyboard (ex.: Pressing Attack many times in a row in a short time)
