飞镖游戏计算

phppermutation
3

我找不到任何有关飞镖的脚本或代码，所以我一直在编写自己的代码。如果有人知道有这些内容的网站，请告诉我（我已经用多种方式搜索了但没有找到）。

我正在尝试制作一个飞镖游戏（301/501）的脚本，它将计算如何完成游戏。游戏在你用飞镖打中一个精确的分数（3、2或1）并且最后一个镖是双倍时结束（例如，得分是170，可以打2个三倍20分（2*60），和一个双倍的靶心（2*25））。

我开始编写一个循环遍历值并提取加起来的第一个值的脚本。然而，我编写得不正确/低效，因为：1.我循环了三次（即使只需要1或2个镖），2.我只输出了要投掷的第一组值，而不是所有值。

Example:
Score 50
 1. double bull (25)
 2. 20 + double 15
 3. 20 + 20 + double 5
 4. 16 + 8 + double 13
 5. double 12 + double 12 + double 1
 6. triple 15 + 1 + double 2
 7. etc.

以下是我开始的内容：

$score = $_GET['score'];
if ($score > 170) {
    die('No Outs');
}
$possdarts = array();
$possdartstext = array();
for ($x = 0; $x < 2; $x++) {
    for ($a = 0; $a < 60; $a++) {
        if (($score - $a) >= 0)  {
            $possdarts[] = $a;
            if(($x == 2) && ($a % 2 == 0)) {
                $outs[] = $a;
            }
        }
    }
}

感谢您的任何帮助。
更新的代码现在遍历了所有值，但没有检查第二个飞镖上的值是否可行。<table border="1"> <?php for ($x=60; $x>0; $x--) { for ($xx=60; $xx>0; $xx--) { for ($xxx=50; $xxx>0; $xxx = $xxx - 2) { if ($xxx == 48) { $xxx = 40; } echo '<tr> <td>' . $x . '</td> <td>' . $xx . '</td> <td>' . $xxx . '</td> <td>' . ($xxx + $xx + $x) . '</td> </tr>'; } } }
?> </table> - user1419338

这是我几年前的账户。如果有人偶然发现了这个帖子，我最终完成了这个代码并分享给大家。

  1. 根据 @bestprogrammerintheworld 的建议更新了变量名。
  2. 允许用户输入他们喜欢的结束镖。
  3. 删除重复项（例如“45, 30, double 2”和“30, 45, double 2”只会显示一次）。

（如果没有此处的文字，编辑器将无法从代码中断开列表。）

我会尝试做这样的事情：（你也必须添加三元组，但这是我开始的方式...）你必须有足够的内存来使用数组...它会占用很多内存。我尝试了170个，php被耗尽了...内存限制。你应该注意这一点。如果你的服务器允许，这并不是真正的问题。

这很接近，尽管它不是按顺序排列的，会出现重复。

得分50的输出将是：48、0、1 双-45、3、1 双-45、1、2 双-42、6、1 双。你说它不是按顺序排列的 - 你希望输出如何呈现？给出前5个或更多的例子。 - bestprogrammerintheworld

一个小建议：你真的应该使用有意义的变量名，而不仅仅是在其后附加一个字母（$x、$xx、$xxx、$xxxx根本没有意义，而且很难阅读）。 - bestprogrammerintheworld
