我的问答游戏中的 draw() 函数无法正常工作

Question

好的，我正在使用 python 制作问答游戏。我拥有它，以便当您的鼠标悬停在其中一个选项上时，它会改变颜色。但是，当我尝试这样做时出现了两个问题。

当我将鼠标悬停在它上面时，只有 answer_box4 实际上会稍微改变颜色。
当我将鼠标悬停在 answer_box4 上时，它会更改所有框的颜色。

代码如下：

     try:
        logname = 'c:/temp/pgzrun.log'
        fontname = 'arial.ttf'
    
        import faulthandler
        faulthandler.enable()
        
        import os, sys
        
        script_dir = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
        os.chdir(script_dir)
        
        import pgzrun
        import playsound

        HEIGHT = 720
    
        def draw():
            screen.fill("purple")
            screen.draw.filled_rect(main_box, "sky blue")
            screen.draw.filled_rect(timer_box, "sky blue")
            screen.draw.text("Score: " + str(score), color="black", topleft=(10, 10), fontname=fontname)
    
            for boxc in answer_boxes:
                screen.draw.filled_rect(box, color)
    
            screen.draw.textbox(str(time_left), timer_box, color=('black'), fontname=fontname)
            screen.draw.textbox(question[0], main_box, color=('black'), fontname=fontname)
    
            index = 1
            for box in answer_boxes:
                screen.draw.textbox(question[index], box, color=('black'), fontname=fontname)
                index = index + 1
    
        def game_over():
            global question, time_left, scoredecreaserps
            scoredecreaserps = 0

            score = score + 1000
    
            if questions:
                question = questions.pop()
                time_left = 10
            else:

        answer_box4 = Rect(735, 538, 495, 165)

Answer 1

每次鼠标经过方框时，您都会迭代所有方框

def on_mouse_move(pos):
            global color 
            for box in answer_boxes:
    
                if box.collidepoint(pos):
                    color = "medium blue"
                    print(color)
    
                else:
                    color = "green yellow"
                    print(color)

最后一个盒子是 box4 answer_boxes = [answer_box1, answer_box2, answer_box3, answer_box4]。最后，如果将 box1 悬停，您会将其颜色更改为蓝色，然后在循环中移动到 box2，进入“else”块并将 box1 的颜色更改为绿色。

为什么？我怀疑是 global color 的声明：每个框指的是相同的颜色。这与 box4 不同并且单击时会更改所有框的颜色这一事实是一致的：作为 for 循环中的最后一个，悬停后会将颜色覆盖为所需的颜色，如果单击会更新所有框的颜色。

您应该将每个框实现为具有自己颜色的对象，然后更改特定框的颜色。
