自动设置与手动减少(如何做到这两者？)

Question

一开始这可能有点复杂，但请您耐心点。我正在做一个城市模拟游戏，我想要实现的是：

1. 看看这座城市的healthStat
2. 如果它在一个范围内，设置daysRemaining (意味着城市的寿命)
3. 每过一天，daysRemaining就会减少。

准则：

healthStat自愿默认daysRemaining

.=‘1’>

.=

-35

-40

我设法解决了这个问题，但是出现了一个问题.我只能做daysRemaining的自动设置，或者手动的减少--我不能两者都做。

这是我的密码：

if (statsHealth <= -10f && statsHealth > -25f)
            {
                //Enable Health Hazard
                isHealthHazard = true;

                //Set Days Remaining
                daysRemaining = 10;
            }
            else if (statsHealth <= -25f && statsHealth > -35f)
            {
                //Enable Health Hazard
                isHealthHazard = true;

                //Set Days Remaining
                if (daysRemaining > 8 || daysRemaining <= 5)
                {
                    daysRemaining = 8;
                }
            }
            else if (statsHealth <= -35f && statsHealth > -40f)
            {
                //Enable Health Hazard
                isHealthHazard = true;

                //Set Days Remaining
                if (daysRemaining > 5 || daysRemaining <= 2)
                {
                    daysRemaining = 5;
                }
            }
            else if (statsHealth <= -40f && statsHealth > -50f)
            {
                //Enable Health Hazard
                isHealthHazard = true;

                //Set Days Remaining
                if (daysRemaining > 2 || daysRemaining < 0)
                {
                    daysRemaining = 2;
                }
            }
            else if(statsHealth >= -50f && hasIssues)
            {
                //GAME OVER
                Debug.Log("GAME OVER!");
                daysRemaining = 0;
            }
            else if(statsHealth >= 0)
            {
                //No More Health Issues
                isHealthHazard = false;
 }

问题是，每当我的比赛一天过去，如果它在healthStat的范围内(例如：-25的healthStat范围在8-6 daysRemaining之间)，它就会减少。但是，如果daysRemaining达到5，它将重置为8，因为它超出了范围(基于healthStat)。

另一方面，如果我根据healthStat的范围禁用autoSetting的daysRemaining，它将用于手动减少。但是，当玩家到达特定的daysRemaining时，我如何在第一时间设置healthStat？

我如何能够同时自动设置daysRemaining，同时能够手动调整它？

PS:我知道这可能有点混乱，所以如果你有任何进一步的询问，请随时评论，我一定会回应。谢谢!

您需要一种方法来确定何时输入或离开健康类别，或者是否已在该类别中。添加一个变量，该变量跟踪上一个类别中的默认天数，并仅根据前一个和新的默认天数之间的差异更改所剩的天数。

此外，还要有一个布尔值来跟踪您以前是否在任何类别之外。这样，如果您以前不在任何类别之外，则只需将剩余天数设置为默认的剩余天数。

以下是这些更改的样子：

private int previousDefaultDaysRemaining;
private bool previousOutsideHealthCategory;

void Start()
{
    previousDefaultDaysRemaining = 1000;
    previousOutsideHealthCategory = true;
} 

然后..。

// initialize to some value reasonable for not being health category.
int newDefaultDaysRemaining = 1000;
bool newOutsideHealthCategory = true;

// Determine what category of health you are in now
if (statsHealth <= -10f && statsHealth > -25f)
{
    //Enable Health Hazard
    isHealthHazard = true;
    newOutsideHealthCategory = false;

    newDefaultDaysRemaining = 10;
}
else if (statsHealth <= -25f && statsHealth > -35f)
{
    //Enable Health Hazard
    isHealthHazard = true;
    newOutsideHealthCategory = false;

    newDefaultDaysRemaining = 8;
}
else if (statsHealth <= -35f && statsHealth > -40f)
{
    //Enable Health Hazard
    isHealthHazard = true;
    newOutsideHealthCategory = false;

    //Set Days Remaining
    newDefaultDaysRemaining = 5;

}
else if (statsHealth <= -40f && statsHealth > -50f)
{
    //Enable Health Hazard
    isHealthHazard = true;
    newOutsideHealthCategory = false;

    newDefaultDaysRemaining = 2;
}

// Decrease timer 
daysRemaining -= 1;

if (previousOutsideHealthCategory) 
{
    // We were not in a category previously, just set the days remaining
    daysRemaining = newDefaultDaysRemaining;
} 
else 
{
    // reduce or increase daysRemaining by any category change
    daysRemaining += newDefaultDaysRemaining - previousDefaultDaysRemaining;
}

// remember the new category's days remaining and 
// our outsideHealthCategory status if either changed
previousDefaultDaysRemaining = newDefaultDaysRemaining;
previousOutsideHealthCategory = newOutsideHealthCategory;

// check for critical health status boundaries
if(statsHealth > -10 && hasIssues)
{
    //GAME OVER
    Debug.Log("GAME OVER!");
    daysRemaining = 0;
}
else if(statsHealth >= 0)
{
    //No More Health Issues
    isHealthHazard = false;
}
