我试图制作一段代码,它最终会掷骰子来决定哪个角色获胜,并且一直说有错误(使用未分配的局部变量' skillmodifier ')&(使用未分配的局部变量' strengthmodifier ' )。我真的很感激任何帮助。PS我只在Visual Studio 2010上做了很短的时间编程。请帮我找到解决这个问题的方法,出现问题是因为我使用变量' strengthmodifier '和' skillmodifier '两次。谢谢你,你忠实的,维卡什。我将粘贴下面的任务 breif 和之后的代码:

任务 3 确定遭遇的结果 当两个角色之间发生遭遇时,结果由以下过程确定:

• 计算两个角色的强度属性之间的差异

• 这个差值除以 5,然后向下取整以创建“强度修正”</p>

• 对技能属性重复该过程以创建“技能修饰符”</p>

• 每个玩家投掷一个 6 面骰子。

• 如果两个骰子的分数相同,则不做任何更改

• 如果分数不同,则得分最高的玩家将“力量修正”添加到其角色的力量值和“技能修正”到其角色的技能值

• 骰子得分较低的玩家从其角色的力量和技能值中减去这些修正值

• 如果技能值变为负数,则将其存储为零

• 如果力量值变为零或负数,则角色死亡。

该计划应:

* • 允许用户输入两个角色的力量和技能。

• 使用上述过程显示遭遇的结果。设计一个算法来描述这个过程。编写、测试和评估代码。*

实际上,我认为您的问题是因为技能修饰符和强度修饰符没有在所有代码路径上获得分配值。IE。它们仅从 if 子句中分配值,并且 Visual Studio 无法确定它们是否分配给所有可能的结果。此警告不应停止您的代码编译,但如果您希望它消失,您可以执行类似的操作

int skillmodifiertoround = 0;

而不仅仅是

int skillmodifiertoround;

现在 Skillmodifiertoround 在声明中被赋予了一个值。

编辑:“此警告不应停止您的代码编译” - 显然它会阻止程序在 c# 中正确编译,但 vb 中的相同错误仅给出警告但仍可编译。

它真的很简单

int skillmodifier;

您需要先分配它 - 即给它一个值,甚至是默认值 - 然后才能使用它。否则程序不知道它有什么价值。

所以像

int skillmodifier = -1;

会为你解决的。

当您int skillmodifier将其声明为默认值时,例如int skillmodifier = 0;

做同样的事情strengthmodifier,你应该很高兴!

问题是编译器可以在不设置这些参数的情况下检测到执行代码的方式。

C# 中的局部变量必须在使用前进行初始化。

来自MSDN

另请参阅相关问题为什么未分配的局部变量不会自动初始化?

对于类型未知的泛型,使用默认关键字

我想其他人已经给了你答案,但我发现了别的东西。

而不是 //method if(tryparse) { //done } else //loop

您应该将方法转换为返回整数的方法,然后...

int csko = loopCsko()
