Unity 中 C# 脚本的问题

Question

如何缩短它？我想我可能是一个数组，但我不知道如何设置它。这是代码，这是当你获得一定数量的金币时需要做的事情：它增加 10 的健康并保存健康，然后它改变显示下一次升级需要多少金币的文本。

Answer 1

有几种不同的方法来处理这个问题，但也许最简单的方法是从一个带有阈值的数组开始（确保它按从小到大的顺序排列）：

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

然后您可以循环遍历您的数组，而不是那组可怕的 if 嵌套：

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

Answer 2

我发现您设置的等级要求（至少达到 450）遵循一定的模式。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，它可以用二次函数表示。所以我写了一个生成和求解这样一个二次函数的方法。
您向它提供基本功能参数（基础、增长）和当前点数（在本例中为黄金），它 returns 玩家达到的等级。

举个例子，我在下面的常量中设置的值几乎符合您首先列出的要求。他们是：

30
70
130
200
280...

我还使用了属性来使 HP 与 PlayerPrefs 保持同步。您可以在此处添加一个支持变量，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文本。
照原样，它似乎过于复杂。我无法想象您实际上需要所有这些单独的文本对象。
你到底想在这里做什么？
