Unity中C＃脚本的问题

Question

如何使它更短？ 我想我可能是一个数组，但是我不知道如何设置它。 这是代码，这是当您获得一定数量的硬币时需要执行的操作：将生命值提高10，并保存生命值，然后更改显示下次升级所需数量的文本。

Answer 1

有几种不同的处理方法，但是最简单的方法可能是从一个带有阈值的数组开始（确保将数组从最小到最大排序）：

var thresholds = new int[] { 30,60,100,150,210,...};

然后，您可以循环遍历数组，而不是可怕的嵌套if集合：

int i = 0;
while (PlayerControl.coins < thresholds[i++])
{
    healthpoints += 10;
}

Answer 2

我意识到您设置的级别要求（至少达到450）遵循某种模式。 每个级别的要求总是增加10。我认为这是管理XP要求的简单但有效的方法。
这种模式的优点之一是可以用二次函数表示。 因此，我写了一种方法来生成和求解这种二次函数。
您向它提供基本功能参数（基本，增长）和当前点（在本例中为黄金），并返回玩家已达到的等级。

举个例子，我在下面的常量中设置的值几乎与您首先列出的要求匹配。 他们是：

1. 三十
2. 70
3. 130
4. 200
5. 280 ...

我还使用了一个属性，使HP与PlayerPrefs保持同步。 您可以在此处添加一个后备变量，以防止一直读取PlayerPrefs。

public class HpManager : MonoBehaviour
{
    public int HealthPoints 
    { 
        get 
        { 
            PlayerPrefs.GetFloat("HealthUP")
        }
        set 
        { 
            PlayerPrefs.SetFloat("HealthUP", value); 
        } 
    }   

    private const uint BASE_HEALTH_POINTS = 100;            // Your HP for level 0
    private const uint HEALTH_POINTS_PER_LEVEL = 10;        // The amount the HP increase with each level

    private const uint BASE_LEVEL_REQUIREMENT = 30;     // The gold required to reach level 1
    private const uint PER_LEVEL_INCREASE = 10;         // The amount the level up requirement increases with every level
    private const uint MAX_LEVEL = 99;


    private void Start()
    {
        HealthPoints = BASE_HEALTH_POINTS;              // Set a base value for your HP
    }

    void HpUpgradelvl()
    {
        int level = GetLevel((uint)PlayerControl.coins, BASE_LEVEL_REQUIREMENT, PER_LEVEL_INCREASE);
        level = Mathf.Clamp(0, MAX_LEVEL);

        HealthPoints = BASE_HEALTH_POINTS + level * HEALTH_POINTS_PER_LEVEL;
    }   

    private int GetLevel(uint points, uint baseRequirement, uint increaseRequirement)
    {
        float a = 0.5f * increaseRequirement;
        float b = baseRequirement - a;

        // Convert quadratic equation "l = ax² + bx" into normalized form "0 = x² + px + q"
        float p = b / a;                                                
        float q = -points / a;                                          // Bring across and normalize
        float level = -p / 2f + Mathf.Sqrt((p * p) / 4f - q);               // Solve for positive value       

        return Mathf.FloorToInt(level);                                     // Return reached level
    }
}

我需要更多信息来帮助您处理这些文本。
照原样，它似乎过于复杂。 我无法想象您实际上将需要所有这些单独的文本对象。
您在这里尝试这样做到底是什么？
