別の質問では、サッカーのシミュレーション アルゴリズムの構築を手伝ってくれました。私はそこにいくつかの非常に良い答えを得ました. 再度、感謝します!
これで、このアルゴリズムをコーディングしました。私はそれを改善し、そこにある可能性のある小さな間違いを見つけたいと思っています. 前回の質問で行ったように、解決方法については議論したくありません。今はそれを改善したいだけです。もう一度私を助けてもらえますか?
- 間違いはありますか?
- ネストされた if 節の構造は大丈夫ですか? 改善できますか?
- 私の説明に従って、戦術は正しく統合されていますか?
ランダム性に影響を与える戦術設定:
- $tactics[x][0] 調整 (1=防御、2=中立、3=攻撃): 値が高いほど防御が弱く、攻撃が強い
- $tactics xプレーの速さ (1=遅い、2=中程度、3=速い): 値が高いほど機会は多くなりますが、素早い反撃を受けるリスクが高くなります。
- $tactics xパスの距離 (1 = ショート、2 = ミディアム、3 = ロング): 値が大きいほどチャンスは少なくなりますが、オフサイドになる頻度が高くなります。
- $tactics x変更の作成 (1 = 安全、2 = 中、3 = 危険): 値が高いほどチャンスは多くなりますが、迅速な反撃を受けるリスクが高くなります。
- $tactics[x][4] 防御におけるプレッシャー (1=低、2=中、3=高): 値が高いほど、カウンター攻撃が速くなります。
- $tactics[x][5] 攻撃性 (1=低、2=中、3=高): 値が高いほど、ファウルによって阻止される攻撃が多くなります
注: 戦術 0 と戦術 4 は、エンジンの残りの部分に部分的に統合されており、この機能では必要ありません。
現在のアルゴリズム:

更新 (2014 年):数年後、ゲームの完全なコード ベースをGitHub でオープン ソースとしてリリースしました。興味のある方は、このファイルにこのシミュレーションの具体的な実装を見つけることができます。
