while 循环无法正常工作

Question

结果是这样的：

1. 你对敌人造成 8 点伤害，敌人还剩 92 点生命值
2. 敌人对你造成 8 点伤害，你还剩 86 hp
3. 你对敌人造成 5 点伤害，敌人还剩 81 点生命值
4. 敌人对你造成 11 点伤害，你还剩 72 hp
5. 你对敌人造成 12 点伤害，敌人还剩 67 点生命值
6. 敌人对你造成 7 点伤害，你还剩 60 hp
7. 你对敌人造成 13 点伤害，敌人还剩 40 点生命值
8. 敌人对你造成 11 点伤害，你还剩 32 点生命值
9. 你对敌人造成 2 点伤害，敌人还剩 33 点生命值
10. 敌人对你造成 15 点伤害，你还剩 16 点生命值
11. 你对敌人造成 15 点伤害，敌人还剩 2 点生命值
12. 敌人对你造成 17 点伤害，你还剩 -11 hp

你死了：-11 hp 敌人获胜！

敌人的生命值是：-8 你赢了！你获得 50 经验！

两者都有 100 hp，正如您在第 2 行看到的那样，当敌人受到 8 点伤害并剩下 86 hp 时，有一个“循环”丢失了。

当其中一个死亡时如何停止循环以使两者不能同时死亡？因此，如果一个人死了，循环就会停止并确定获胜者。

有没有更好的方法来确定从随机开始？

<?php

$p_hp = 100;
$p_atk = 20;
$p_defence = 5;

$m_hp = 100;
$m_atk = 20;
$m_defence = 5;

if ($p_hp > 0) {

    $turn = rand(0,1);
    $hitnr = 0;

    while (($p_hp >= 0) && ($m_hp >= 0)) {

        $turn--;
        $hitnr++;

        $enemydef = $p_atk - $m_defence / 2;
        $my_damage = rand(1, $enemydef);

        $playerdef = $m_atk - $p_defence / 2;
        $enemy_damage = rand(1, $playerdef);

        $p_hp = $p_hp - $enemy_damage;
        $m_hp = $m_hp - $my_damage;

        // Player turn
        if ($turn % 2 == 0) {
            echo "<b>".$hitnr.".</b> Enemy hit you for  <font color='red'><b>".$enemy_damage . "</b></font> damage you have <b>".$p_hp." hp</b> left<br>";    

        // Monster turn    
        } else {
            echo "<b>".$hitnr.".</b> You hit enemy for  <font color='green'><b>".$my_damage . "</b></font> damage enemy has <b>".$m_hp." hp</b> left<br>";
        }

        if ($p_hp <= 0) {
            echo "<br>You died: ".$p_hp." hp<br><font color='red'><b>Enemy wins!</b></font>";
         }

        if ($m_hp <= 0) {
            echo "<br>Enemy hp is: ".$m_hp."<br><font color='green'><b>You win! You gain 50 exp!</b></font>";

        }
    }
} else {
    echo "You are dead. <a href='hospital.php'>Go to the hospital!</a>";
}

?>

除非怪物（或玩家）可以反击，否则只有目标的HP应该减少：

$p_hp = 100;
$p_atk = 20;
$p_defence = 5;

$m_hp = 100;
$m_atk = 20;
$m_defence = 5;

if ($p_hp >= 0) {

    $turn = rand(0,1);
    $hitnr = 0;

    while (($p_hp >= 0) && ($m_hp >= 0)) {

        $turn--;
        $hitnr++;

        $enemydef = $p_atk - $m_defence / 2;
        $my_damage = rand(1, $enemydef);

        $playerdef = $m_atk - $p_defence / 2;
        $enemy_damage = rand(1, $playerdef);

        // Monster turn
        if ($turn % 2 == 0) {
            $p_hp = $p_hp - $enemy_damage;
            echo "<b>".$hitnr.".</b> Enemy hit you for  <font color='red'><b>".$enemy_damage . "</b></font> damage you have <b>".$p_hp." hp</b> left<br>";    

        // Player turn    
        } else {
            $m_hp = $m_hp - $my_damage;
            echo "<b>".$hitnr.".</b> You hit enemy for  <font color='green'><b>".$my_damage . "</b></font> damage enemy has <b>".$m_hp." hp</b> left<br>";
        }

        if ($p_hp <= 0) {
            echo "<br>You died: ".$p_hp." hp<br><font color='red'><b>Enemy wins!</b></font>";
         }

        if ($m_hp <= 0) {
            echo "<br>Enemy hp is: ".$m_hp."<br><font color='green'><b>You win! You gain 50 exp!</b></font>";

        }
    }
} else {
    echo "You are dead. <a href='hospital.php'>Go to the hospital!</a>";
}
