Question

我在编码时遇到问题。当我回到Unity并玩游戏时，基于文本的游戏开始在＆＃34; Wake Up＆＃34;按照指示的场景。但是，游戏对按下的任何按键都没有响应。场景永远不会改变，它会停留在＆＃34;唤醒＆＃34;除非我手动到sNextHeading选项卡并输入不同的场景名称。例如，我输入＆＃34; Check Woven Basket＆＃34;那场景加载。我知道我的所有场景都有效，但它们对按键没有反应。我在学校看了我的讲座，看起来很相像。我必须忽略一些事情，我希望有人能指出我正确的方向。

Page[] aBook;

public string sPrevHeading;
public string sCurrHeading;
public string sNextHeading = "Wake Up";

void Start()
{

    BindBook();
    RenderStory();
}

void Update() //Input Keys Don't Work
{ 
    if (Input.GetKeyDown(KeyCode.W))
    {
        if (sCurrHeading == "Wake Up")
        {
            sNextHeading = "Check Woven Basket";
        }
    }
    else if (Input.GetKeyDown(KeyCode.D))
    {
        if (sCurrHeading == "Wake Up")
        {
            sNextHeading = "Check Door";
        }
        else if (sCurrHeading == "Pick Up")
        {
            sNextHeading = "Drink Milk";
        }
    }
    else if (Input.GetKeyDown(KeyCode.B))
    {
        if (sCurrHeading == "Wake Up")
        {
            sNextHeading = "Check Bowl";
        }
    }
    else if (Input.GetKeyDown(KeyCode.P))
    {
        if (sCurrHeading == "Bowl")
        {
            sNextHeading = "Pick Up";
        }
        else if (sCurrHeading == "Pick Up")
        {
            sNextHeading = "Pour Milk";
        }
    }
    else if (Input.GetKeyDown(KeyCode.Y))
    {
        if (sCurrHeading == "Drink Milk" ||
            sCurrHeading == "Pour Milk")
        {
            sNextHeading = "Wake Up";
        }
    }
    else if (Input.GetKeyDown(KeyCode.N))
    {
        if (sCurrHeading == "Drink Milk" ||
            sCurrHeading == "Pour Milk")
        {
            sNextHeading = "Thank You";
        }
    }

    RenderStory();
}

void RenderStory()
{
    if (!string.IsNullOrEmpty(sNextHeading))
    {
        for (int nPage = 0; nPage < aBook.Length; nPage++)
        {
            if (sNextHeading == aBook[nPage].Heading)
            {
                sCurrHeading = sNextHeading;
                sNextHeading = "";

                Debug.Log(aBook[nPage].Body);
            }
        }
    }
}

void BindBook()
{
    aBook = new Page[]
    {
        new Page("Wake Up", "(Wake Up)\nCheck the [W]oven Basket, [B]owl, or check the [D]oor?"),
        new Page("Check Woven Basket", "(Woven Basket)\n[X] to return to previous step."),
        new Page("Check Bowl", "(Check Bowl)\n[P]ick up bowl of mile or [X] to return."),
        new Page("Check Door", "(Check Door)\n[X] to return to previous step."),
        new Page("Pick Up", "(Pick Up)\n[P]our out the milk, [D]rink the liquid or [X] to return to previous step."),
        new Page("Pour Milk", "(Pour Milk)\nWin Play again [Y]es or [N]o?"),
        new Page("Drink Milk", "(Drink Milk)\nLose Play again [Y]es or [N]o?"),
        new Page("Thank You", "(Thank You)\nThank you for playing!")
    };

}

}

Answer 1

我认为当您开始游戏时，sCurrHeading实际上是null：它在此代码段中说明了这一点：

public string sCurrHeading;
public string sNextHeading = "Wake Up";

将其更改为

public string sCurrHeading = "Wake Up";
public string sNextHeading;

可能有帮助。

因为它是null，所有这些检查（例如if (sCurrHeading == "Wake Up")）都会失败，而else语句也会失败。

好吧所以我一直在尝试每个人都建议的所有有用选项，我找到了解决问题的方法。我试图搜索的关键词与我在数组中设置的不匹配。例如，＆＃34;碗＆＃34;与＃34;检查碗。＆＃34;我正在检查的标题没有与我创建的标题完全匹配。但是，我写下了所有这些可能的修复，以防我将来遇到问题。再次感谢你！
