java - 重建一些代码以根据概率返回损坏或未命中(游戏)

Question

你好，我正在尝试基于概率实现战斗和准确性。这是我的代码，但效果不太好。

public String setAttackedPartOfBodyPercent(String probability) {
    return this.probability = probability;    // from 0% - 100%
}

private int generateDamage() {
    int miss = generateMiss(probability)+1);
    damage = (new Random().nextInt(30 + getStrength()) + 1) * miss;
    if (damage == 0)
        gs.canvas.drawText("miss", (float) gs.chibi1.getX(), (float) gs.chibi1.getY(), pt.pBlack);
    return damage;
}

public int generateMiss(int accuracy) {
    if (accuracy < 100) 
        return new Random().nextInt((100 / accuracy)+1) > 0 ? 1 : 0;
    else
        return 1;
}

Answer 1

正确答案是

   public int generateMiss(int accuracy) {
        if (accuracy == 100) return 1;
        return (new Random().nextInt(101) < accuracy) ? 1 : 0;
    }
