在在线游戏中，您可以实现奖励和其他能源目标。一个人可能需要总共24,000个能量，这是一个基于时间的能量，而其他人只有25个。基于0能量开始并且在用户睡觉或其他什么时没有失去的能量，我想计算需要多长时间才能获得所需的能量。
--------------------------------------------------------------------
| Energy | Cooldown | Additional | Limit | wait |
| | | Energy | | |
--------------------------------------------------------------------
| Natural | 10 minutes | 5 | N/A | Y |
| Booster 1 | 24 hours | 150 | 1 p/24h | Y |
| Booster 2 | 6 hours | 150 | 4 p/24h | N |
| Booster 3 | 6 hours | 250 | 4 p/24h | Y |
--------------------------------------------------------------------
一个人在24小时内所能达到的总能量是2,470个，通过720个自然能量，150个来自Booster 1,600个来自Booster 2，1,000个来自Booster 3。
所以你每10分钟（600秒）就能获得5点自然能量，你可以通过助推器补充能量，立即增加“冷却时间”。所以基于从0能量开始，你可以跳到1000能量。 “等待”意味着你需要等到冷却时间结束或不结束。
为计算天数，我做了以下工作：
$days = floor($Energy_Needed / 2470) * 86400;
对于剩余的能量，我已经完成了以下工作：
$remaining = $Energy_Needed - (floor($Energy_Needed / 2470) * 2470);
计算出$days之后，再次开始新的问题是if $remaining > 1000（因为用户可以跳到此，所以它只是N天）我怎样才能找到最好的剩余时间？
注意：我只是在寻找总秒数，没有“漂亮”。
答案 0 :(得分：5)
尝试这样的事情。我很难理解这个问题！
实际上这是一个经过测试的工作示例。 我做了这些假设：
1）任何有助推器的球员都会获得自然能量
2）等待时间不会影响THE BOOSTER2

答案 1 :(得分：2)
为什么你乘以86400？这是秒数，而不是几天。
其余的看起来是正确的。但是我会使用modulo（％）运算符。
所以，从剩下的我们首先减去1000，为你的助推器。然后，如果剩下的是小于180，即在6小时内获得的自然能量，你只需将其除以0.5（5能量/ 10分钟）以得到剩余的分钟数。
如果有更多，减去250 + 180并在所需时间增加6小时。然后再将它与180进行比较，如果更大则重复此步骤（如果需要则多次），否则请参见上文。
编辑：如果减去250 + 180后该值为负，则表示您使用助推器达到该值。对于24000能量的例子，情况确实如此，因此需要9天12小时。
-----我认为下面的代码是正确的，没有经过测试-----
$BOOSTER3_ENERGY = 250;
$NAT_EN_6H = 180;
$days = floor($Energy_Needed / 2470);
$remaining = $Energy_Needed % 2470;
$seconds = 0;
if ($remaining > 1000)
{
$remaining -= 1000;
while ($remaining > 0)
{
if ($remaining <= $NAT_EN_6H)
{
$seconds += (ceil($remaining / 5)) * 10 * 60;
break;
}
else
{
$seconds += 6 * 60 * 60;
$remaining -= $NAT_EN_6H + $BOOSTER3_ENERGY;
}
}
}
