風来のシレンDS (DS) > 確率

乱数

32-bit 疑似乱数生成器を用いており、その状態 x は次の式で更新されます: x ← (x × 0x5d588b65 + 1) mod 2^{32}
乱数 0〜(n-1) は (x / 2^{16}) × n / 2^{16} によって取得されます。

ダメージ計算式

シレンからモンスターへの攻撃

• (パワーアップ状態込みのダメージ量) := floor((ダメージ量) × (パワーアップ回数依存の乗数))
• (ダメージ量) := floor((基本ダメージ量) × (特攻倍率) × (乱数 87〜111) / 100) （ただし、最小ダメージは 1、最大ダメージは 999 とする）
• (基本ダメージ量) := round((剣の強さ依存のダメージ量) + (Lv 依存のダメージ量) + (ちから依存のダメージ量) - (対象の防御力))
• (剣の強さ依存のダメージ量) := 52428 × (剣の強さ) / 65536.0 (≈ 0.8 × (剣の強さ))

モンスターからシレンへの攻撃

• (ダメージ量) := round((655 × (モンスターの攻撃力) × (乱数 87〜111) - 51200 × (盾の強さ)) / 65536.0) （ただし、最小ダメージは 1、最大ダメージは 999 とする）

Lv 依存のダメージ量

補足: 正確な値は (括弧内の値)/65536.0 です。
