使用tkinter获取矩形以在文本上绘制

Question

我正在尝试制作剪刀石头布游戏，但我不知道如何在文本上绘制矩形。 这是我的代码：

class game:
    def __init__(self):
        self.choices = ['Rock','Paper','Scissors']
        self.final_human_score = 0
        self.final_computer_score = 0
        rock_b = Button(canvas,text="Rock",bg='black',fg='green',command=self.rock)
        rock_b.place(x=225,y=40)
        paper_b = Button(canvas,text="Paper",bg='black',fg='green',command=self.paper)
        paper_b.place(x=290,y=40)
        scissors_b = Button(canvas,text="Scissors",bg="black",fg='green',comman=self.scissors)
        scissors_b.place(x=360,y=40)
        self.human_turn = False
        self.computer_turn = True

    def turn(self):
        start_x = 75
        start_y = 100
        start_x2 = 90
        start_y2 =200
        Turn = canvas.create_rectangle(start_x,start_y,50,50,fill='green')
        not_turn = canvas.create_rectangle(start_x2,start_y2,50,50,fill='red')

    def rock(self):
        if self.human_turn == False:
            #280,90,400,113
            self.choice_display = canvas.create_text(310,100,text="Rock",fill="white",font=('Courier',13))
            global human_turn #global required to change human_turn and commputer_turn
            global computer_turn
            self.human_turn = True
            self.computer_turn = False
            self.cc()

    def paper(self):
        if self.human_turn == False:
            self.choice_display = canvas.create_text(315,100,text="Paper",fill="white",font=('Courier',13))
            global human_turn
            global computer_turn
            self.human_turn = True
            self.computer_turn = False
            self.cc()

    def scissors(self):
        if self.human_turn == False:
            self.choice_display = canvas.create_text(330,100,text="Scissors",fill="white",font=('Courier',13))
            global human_turn
            global computer_turn
            self.human_turn = True
            self.computer_turn = False
            self.cc()

    def cc(self): #(computer choice)
        computer_choice = random.choice(self.choices)
        if self.computer_turn == False:
            if computer_choice == 'Rock':
                self.c_choice_display = canvas.create_text(310,200,text="Rock",fill="white",font=("Courier",13))
                global human_turn
                global computer_turn
                self.human_turn = False
                self.computer_turn = True
            elif computer_choice == 'Paper':
                self.c_choice_display = canvas.create_text(315,200,text="Paper",fill="white",font=("Courier",13))
                global human_turn
                global computer_turn
                self.human_turn = False
                self.computer_turn = True
            elif computer_choice == 'Scissors':
                self.c_choice_display = canvas.create_text(330,200,text="Scissors",fill="white",font=("Courier",13))
                global human_turn
                global computer_turn
                self.human_turn = False
                self.computer_turn = True

在游戏课中，我如何让它等待3秒钟，然后掩盖计算机的选择和人类的选择？

Answer 1

从Tk手册中了解画布小部件中的窗口：

注意：由于管理窗口的方式的限制，无法在窗口项的顶部绘制其他图形项（例如线条和图像）。 窗口项始终会遮盖与其重叠的所有图形，无论它们在显示列表中的顺序如何。

您的解决方案可以使用可以相互重叠的画布绘制元素。 我没有更改turn方法的工作方式，但是程序中存在泄漏。 您应该在init （）中创建一次overlay元素，然后可以在画布上升高，降低或移动它们。 但是turn方法每次调用都会创建一个新的矩形。
