使用箭头键控制菜单并输入

时间:2017-10-24 10:28:39

标签: c# colors arrow-keys

我正在尝试创建一个RPG。我的菜单有问题,我可以选择一个班级。 我正在尝试创建一个菜单,您可以使用箭头键控制指向特定类的方向,然后以前景颜色红色突出显示,就像在真实游戏中,当您想要选择某些内容时,只需使用箭头键和你所关注的事情得到了强调。

我的问题是当我按箭头键时无法指定箭头键的位置。我只能去第一个位置而另一个问题是当我突出显示rpg类以向用户显示他所在的位置时,所有rpg类都获得前景色。我使用Console.Read来分隔它们,但现在我必须按 Enter 来更改颜色。

这是代码。我想在你打开代码之后你会理解我的问题。

最好的问候Csharpnoob61。

不是手工编写每个组合,而是我要做的事情:使用辅助类来处理常见任务,例如这些多选操作,传递一组选项并等待用户进行选择。 / p>

public class ConsoleHelper
{
    public static int MultipleChoice(bool canCancel, params string[] options)
    {
        const int startX = 15;
        const int startY = 8;
        const int optionsPerLine = 3;
        const int spacingPerLine = 14;

        int currentSelection = 0;

        ConsoleKey key;

        Console.CursorVisible = false;

        do
        {
            Console.Clear();

            for (int i = 0; i < options.Length; i++)
            {
                Console.SetCursorPosition(startX + (i % optionsPerLine) * spacingPerLine, startY + i / optionsPerLine);

                if(i == currentSelection)
                    Console.ForegroundColor = ConsoleColor.Red;

                Console.Write(options[i]);

                Console.ResetColor();
            }

            key = Console.ReadKey(true).Key;

            switch (key)
            {
                case ConsoleKey.LeftArrow:
                {
                    if (currentSelection % optionsPerLine > 0)
                        currentSelection--;
                    break;
                }
                case ConsoleKey.RightArrow:
                {
                    if (currentSelection % optionsPerLine < optionsPerLine - 1)
                        currentSelection++;
                    break;
                }
                case ConsoleKey.UpArrow:
                {
                    if (currentSelection >= optionsPerLine)
                        currentSelection -= optionsPerLine;
                    break;
                }
                case ConsoleKey.DownArrow:
                {
                    if (currentSelection + optionsPerLine < options.Length)
                        currentSelection += optionsPerLine;
                    break;
                }
                case ConsoleKey.Escape:
                {
                    if (canCancel)
                        return -1;
                    break;
                }
            }
        } while (key != ConsoleKey.Enter);

        Console.CursorVisible = true;

        return currentSelection;
    }
}

上面的例子可以像这样使用:

int selectedClass = ConsoleHelper.MultipleChoice(true, "Warrior", "Bard", "Mage", "Archer", 
    "Thief", "Assassin", "Cleric", "Paladin", "etc.");
函数返回时,

selectedClass将只是所选选项的索引(如果用户按下escape,则为-1)。您可能希望添加其他参数,例如横幅文本(“选择类”)或格式化选项。

应该是这样的:

Console output

您当然可以添加其他标记,例如_these_> those <,以进一步突出显示当前选择。
