Summary of Changes

Hello @xiaoxustudio, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a bug where the 'fast button' in the WebGAL application could display an incorrect state, failing to synchronize with the actual gameplay speed. The implemented change ensures that the button's visual representation accurately mirrors the underlying game logic, thereby enhancing the user interface's reliability and responsiveness.

Highlights

• Fast Button State Synchronization: Introduced a new useEffect hook in useHotkey.tsx to ensure the fast button's UI state (setFastButton) correctly reflects the WebGAL.gameplay.isFast property. This change addresses an issue where the button's visual state might not update consistently with the game's fast-forward status.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• packages/webgal/src/hooks/useHotkey.tsx
  • Added a useEffect hook to synchronize the setFastButton state with WebGAL.gameplay.isFast.

Code Review

This pull request attempts to fix a state synchronization issue with the 'fast' button by adding a useEffect hook. However, the implementation is based on a common misconception about how useEffect dependencies work with external mutable state. The added effect will not trigger as expected, so the underlying bug is not fixed. I've provided a comment explaining the issue in detail and suggesting alternative approaches.
