TKINTER，使用按钮进行文字冒险游戏-解网

问：

我想做一个基于文本的冒险游戏。这似乎很容易，我只是制作了一个巨大的if语句树，并在每一步都从用户那里获得输入。但是，后来我决定尝试使用 Tkinter 制作一个 GUI。问题是我不知道如何从其中一个按钮获取输入并推进游戏。

我尝试将选择变量实现为 ch。按钮触发更改 ch 的方法。我希望我能检测是否进行了输入并获取 ch 变量。但是，尽管位于主循环中，但 if 语句不会触发。

以下是完整代码：


import tkinter as tk


root = tk.Tk()
    #self.root.iconbitmap('')
root.geometry("800x500")
root.title("Diego's Adventure Extravaganza!")

class GUI:
    def __init__(self,master):
        #the charecter will be able to make choices
        self.ch =5
        self.index=0
        #this will display the chapter the charecter is on
        self.title = tk.Label(master, text="Text for titile", font=('Arial',18))
        self.title.pack()

        #relivent story details
        self.storyframe = tk.Frame(master)
        self.storyframe.columnconfigure(0, weight=1)
        self.storyframe.columnconfigure(1, weight=1)

        self.photo = tk.PhotoImage(file='images/pngtest.png')
        self.image = tk.Label(self.storyframe, image=self.photo, width= 300, height = 150)
        self.image.grid(row=0,column=0,sticky=tk.W+tk.E)

        self.story= tk.Label(self.storyframe, text="this is where the story goes")
        self.story.grid(row=0,column=1,sticky=tk.W+tk.E)

        self.storyframe.pack(fill='x')

        self.buttonframe=tk.Frame(master)
        self.buttonframe.columnconfigure(0,weight=1)
        self.buttonframe.columnconfigure(1,weight=1)

        #the choices the chatecter can make at the moment
        self.btmZ= tk.Button(self.buttonframe,text="The zero's button", command= self.clickZ)
        self.btmZ.grid(row=0, column=0, sticky=tk.W+tk.E)

        self.btmO= tk.Button(self.buttonframe,text="the first button", command= self.clickO)
        self.btmO.grid(row=0, column=1, sticky=tk.W+tk.E)

        self.btmT= tk.Button(self.buttonframe,text="the third button", command= self.clickT)
        self.btmT.grid(row=1, column=0, sticky=tk.W+tk.E)

        self.btmTh= tk.Button(self.buttonframe,text="the fourth button",command= self.clickTh)
        self.btmTh.grid(row=1, column=1, sticky=tk.W+tk.E)

        self.buttonframe.pack(fill='x')

    def clickZ(self):
        self.ch=0
    def clickO(self):
        self.ch=1
    def clickT(self):
        self.ch=2
    def clickTh(self):
        self.ch=3

    def cTitle(self,ctext):
        self.title.config(text=ctext)
    def cImage(self,cpath):
        self.photo.config(file=cpath)
    def cStory(self,ctext):
        self.story.config(text=ctext)
    def cBtmText(self,ctext,num):
        if num==0:
            self.btmZ.config(text=ctext)
        elif num == 1:
            self.btmO.config(text=ctext)
        elif num == 2:
            self.btmT.config(text=ctext)
        else:
            self.btmTh.config(text=ctext)

win = GUI(root)

#The main program
#trying to test the buttons, I want a branching story and for the buttons to do many things
if win.ch ==0:
    win.cTitle("Chapter 1")
elif win.ch == 1:
    win.cStory("The story begins")
elif win.ch == 2:
    win.cbtmText("This is the best button", 2)
else:
    win.ch =5
root.mainloop()

将代码放在调用上方不会将其置于主循环中。我建议直接从函数回调（、、等）运行、和函数root.mainloop()cTitlecStorycbtmTextclickZclickO

这是一个糟糕的解决方案：您必须退出程序才能继续前进。

如果您无法返回按钮输入，那么拥有 GUI 类的意义何在？

上一个：使用 MSVC 编译器和 GCC 编译器时获得的结果不同

下一个：std：:p air 的两个条目的销毁顺序是什么？
