はじめに
Amazon Q CLI でゲームを作ろう Tシャツキャンペーンに応募します！
せっかくなので、 Elixir の Phoenix LiveView で作ってもらいます
Amazon Q CLI が実装したコードはこちら
Amazon Q CLI とは
本人に聞いてみました
> Amazon Q CLI とは何ですか
Amazon Q CLI は、AWS が提供するコマンドラインインターフェース（CLI）ツールです。これを使用すると、ターミナルやコマンドプロンプトから直接 Amazon Q の AI アシスタント機能にアクセスできます。
主な特徴:
• ターミナル内で AI アシスタントと対話できる
• ローカルファイルシステムの操作（ファイルの読み書き、ディレクトリの一覧表示など）
• Bash コマンドの実行
• AWS CLI 呼び出しによる AWS リソースの管理・照会
• コードの作成や修正のサポート
• AWS サービスに関する質問への回答
• インフラストラクチャコードや設定のサポート
• ベストプラクティスのガイダンス
• トラブルシューティングのサポート現在、あなたは q chat コマンドを使用して私（Amazon Q）と対話しています。より詳細な使用方法については、q --help コマンドを実行すると確認できます。
> 仕組みを Mermaid.jsの図で表してください
Mermaid.js を使って Amazon Q CLI の仕組みを図で表現します。以下のコードをファイルに保存して、Mermaid.js レンダラーで表示できます：

● Path: /Users/rwakabay/amazon_q_cli_diagram.mdAmazon Q CLI の仕組みを Mermaid.js で表現した図を作成し、amazon_q_cli_diagram.md というファイルに保存しました。この図は以下のような構造を示しています：
ユーザーとの対話:
• ユーザーが Amazon Q CLI と対話
• CLI が Amazon Q AI サービスと通信ローカル環境での操作:
• ファイルシステムの操作
• Bash コマンドの実行
• AWS CLI の呼び出しAWS クラウド側の処理:
• 大規模言語モデルによる処理
• AWS サービス情報の提供
• コード生成エンジンの活用この Mermaid.js コードをブラウザベースの Mermaid エディタ（例：https://mermaid.live）にコピー＆ペーストすると、視覚的な図として表示できます。また、多くのマークダウンエディタや GitHub などでも、このコードを含むマークダウンファイルを開くと図として表示されます。
料金は以下を参照してください
今回は無料利用枠で使用しますが、無料で十分ゲームを実装できました
Amazon Q CLI のインストール
Amazon Builder ID に登録します
公式の手順に従って Amazon Q CLI をインストールします
Amazon Q CLI への指示
q コマンドを実行すると、 Amazon Q CLI とのチャットが開始されます

以下のように指示を与えてみました
Phoenix LiveView を使って、ブラウザで遊べるブロック崩しを作ってください。データベースは不要です。
すると、以下のように Elixir のバージョンを確認しようとします
信頼しているので、 t （Trust） と回答し、以降のコマンドの実行を許可します
I'll help you create a block breaker game using Phoenix LiveView that can be played in the browser without requiring a database. Let's build this step by step.
First, let's create a new Phoenix project with LiveView:
🛠️ Using tool: execute_bash

We are almost there! The following steps are missing:
$ cd block_breaker
Start your Phoenix app with:
$ mix phx.server
You can also run your app inside IEx (Interactive Elixir) as:
$ iex -S mix phx.server

You're right, I missed assigning those important game constants to the socket. Let's fix the mount function in the game_live.ex file to include all the necessary
constants.

● Completed in 0.0s
I've updated the mount function in the game_live.ex file to include all the necessary game constants in the socket assigns. This will fix the error you were
encountering.
The updated mount function now assigns these additional values to the socket:
• game_width
• game_height
• paddle_width
• paddle_height
• ball_radius
• block_width
• block_height
These constants are needed in the template to properly render the game elements. Now when you reference these values in the template with @game_width,
@paddle_width, etc., they will be available from the socket assigns.
You should now be able to run the game without errors. To start the Phoenix server, you can run:
cd /Users/rwakabay/block_breaker
mix phx.server
Then visit http://localhost:4000/game in your browser to play the block breaker game.
The game features:
• A paddle you can control with mouse movement or arrow keys
• A bouncing ball that reflects off walls, blocks, and the paddle
• Multiple rows of colorful blocks to break
• Score tracking
• Game states (ready, playing, game over)
• Press Space to start the game or restart after game over
