はじめに

遅ればせながら『Amazon Q CLi Developer でゲームを作ろう』のキャンペーンに応募すべく、ゲームを作成しました。
Amazon Q Developer CLI はリリース当初からお世話になっている推しAIツールので、このTシャツは絶対に欲しい。

動作環境

Windows 11
WSL2
- ubuntu
Amazon Q Developer CLI

セッティング

丁度、Claude4へのモデル変更が可能になったアップデートが入っていたので、せっかくなので最新のClaudeのモデルの性能も確認すべく、モデルの変更を実施。

/modelでモデル変更の選択肢が現れ、変更が可能に。
もちろん claude4-sonnetを選択。
毎度ですがターミナルに表示されるAAにはロマンがありますね...

q chat --model claude-4-sonnetで起動時のモデルをclaude4に変更できるので、マストで変更しておきます。

今回作ったもの

インベーダーゲーム

ベタですがレトロゲームをサクッと作ってみたかったのでインベーダーゲームにしました。

実装

Claude4のパワーもあり、3,4回のやり取りで完成しました。

一発目の出力でほぼほぼインベーダーゲームとしての機能はできあがりました。

自機・敵機の存在
自弾・敵弾の当たり判定
衝突判定からの消滅
左右への移動・全身

しかしながら自機も敵機も完全に豆腐で色気が無さすぎるので、もう少しグラフィカルに、かつゲーム性を持たせるためスコア表示機能の追加を依頼。

追加で以下の機能も実装しました。

残機の追加
ステージの概念(3面クリアで終了)
クリアタイムの記録
GAME OVER 機能
敵弾が命中した際の点滅エフェクト
自弾が命中した際の爆発エフェクト

開始時は敵機の数が多いのでなかなかの弾幕が降り注ぎます。

舐めてると意外と簡単にやられてしまいますね。

3面倒しきるとクリアです！

まとめ

普段はAWSリソースのパラメータ取得やエラー調査ばかり依頼しているAmazon Q Developer CLIですが、Claude4にアップグレードしたこともあり、これくらいのゲームなら余裕で作ってくれますね。

リリース当初から頻繁なアップデートによりどんどん使いやすくなっていくAmazon Q Developer CLI 君に今後も期待しています！！

作成してくれたコード
