问题描述

我正在制作一个 RPG,我有一个怪物遭遇功能,我在其中为敌人的攻击添加权重和模式,并且我可以在调用该功能时对其进行编辑:

数组和变量可以同时作为同一个函数的参数吗?如果没有,是否有任何替代方案可以实现相同的目标?

static void MonsterEncounter(float hp = 10, float speed = 3, float attack = 2, string monName = "Monster",  float exp = 200F, float gold = 30, bool boss = false, bool doubleBattle = false, bool twoEnemy = false, float hpTwo = 10, float speedTwo = 10, float attackTwo = 1, string monNameTwo = "Monster 2", int teamMate = 0, string status = "Fine", string powerAttack = "Super Hit", float powerAttackHit = 10, float powerAttackHeal = 2, bool isHealing = false, bool isDefending = false, int waitTime = 0, string statusAfflict = "null", bool hasWeight = true, bool hasPattern = false, string statusTwo = "Fine",string powerAttackTwo = "Super Hit", float powerAttackHitTwo = 10, float powerAttackHealTwo = 2, bool isHealingTwo = false, bool isDefendingTwo = false, int waitTimeTwo = 0,string statusAfflictTwo = "null", bool hasWeightTwo = true, bool hasPatternTwo = false, int[] patternTwo = {1, 1, 1, 1, 1,1 ,1, 1, 1, 1}, int[] weight = {0, 0, 0, 0},  int[] pattern = {1, 1, 1, 1, 1,1 ,1, 1, 1, 1}, int[] weightTwo = {0, 0, 0, 0}) 

但这是相关的:

int[] patternTwo = {1, 1, 1, 1, 1,1 ,1, 1, 1, 1}, int[] weight = {0, 0, 0, 0},  int[] pattern = {1, 1, 1, 1, 1,1 ,1, 1, 1, 1}, int[] weightTwo = {0, 0, 0, 0}

但我在这里一直收到同样的错误:

    main.cs(4265,254): error CS1525: Unexpected symbol '{'
main.cs(4265,255+): error CS1737: Optional parameter cannot precede required parameters
main.cs(4265,254): error CS1525: Unexpected symbol '1'

我尝试以不同的方式声明变量:

 int[] patternTwo = new int[10] {1, 1, 1, 1, 1, 1, 1, 1, 1, 1}, int[] weight = new int[4] {0, 0, 0, 0},  int[] pattern = new int[10] {1, 1, 1, 1, 1, 1, 1, 1, 1, 1}, int[] weightTwo = new int[4] {0, 0, 0, 0}

但它仍然产生错误:

    main.cs(4265,255+): error CS1736: The expression being assigned to optional parameter 'patternTwo' must be a constant or default value
    main.cs(4265,255+): error CS1736: The expression being assigned to optional parameter 'weight' must be a constant or default value
    main.cs(4265,255+): error CS1736: The expression being assigned to optional parameter 'pattern' must be a constant or default value
    main.cs(4265,255+): error CS1736: The expression being assigned to optional parameter 'weightTwo' must be a constant or default value

我通过谷歌搜索,但我找到的页面要么使用不同的编程语言,要么不涵盖我的要求。

我可以将数组作为参数传递给 Java 中具有可变参数的方法吗?

具有无限参数的 c# 方法或具有数组或列表的方法?

将数组作为参数传递(C# 编程指南)

在 C# 中将数组作为参数传递

数组和变量可以同时作为同一个函数的参数吗?如果没有,是否有任何替代方案可以实现相同的目标?

解决方案


这不是一个“真正的”解决方案,而是一种解决方法。您可以将默认数组值设置为null,然后使用 if 语句设置所需的数组值

        static void MonsterEncounter(float hp = 10, /*[...]*/ int[] patternTwo = null, int[] weight = null,  int[] pattern = null, int[] weightTwo = null){
        if (patternTwo == null) { pattern = new int [] { 1, 1, 1, 1, 1, 1, 1, 1, 1, 1}; }
        //[...]
        if (weightTwo == null) { weightTwo = new int[] { 0, 0, 0, 0 }; }

    }

否则,您也可以使用重载。
