读取问题

如下所示，我们在文本中写了一个问题，然后将其读取出来。

“黄河远上白云间，一片孤城万仞山。”的作者是谁？

王之涣

李白

白居易

杜甫


file = open("1.txt", "r")
question_coll = file.readlines()
file.close()
print(file)

运行之后发现报错，查询之后发现编码格式不正确。

设置了读取的编码格式发现可以读取文本的内容


file = open("1.txt", encoding='utf-8')

绘制回答面板

为了方便读取，新建一个类来储存文件中的问题


# 问题类
class Question:

    # 回答列表
    answer_question = []

    # 正确答案
    answer_index = 1

    """问题类"""
    def __init__(self, question):
        self.question = question

导入问题，将文件中的问题保存在qustion中


from question import Question

因为文件的格式是固定的以6为一个问题的所有行数。

将问题


questionList = []
for i in range(int(len(question_coll) / 6)):
    que_all = question_coll[i * 6: i * 6 + 6]
    que = Question(que_all[0].rstrip())
    que.answer_question = [que_all[1].rstrip(), que_all[2].rstrip(), que_all[3].rstrip(), que_all[4].rstrip()]
    que.answer_index = int(que_all[5].rstrip())
    questionList.append(que)

封装屏幕上显示文字的打印


def draw_text(window_screen, font_size, content, starting_x, starting_y, text_color=WHITE, bg_color=BLACK):
    # 绘制文字
    # 设置字体
    font = pygame.font.SysFont("方正粗黑宋简体", font_size)
    text1 = font.render(content, True, text_color, bg_color)
    window_screen.blit(text1, (starting_x, starting_y))

显示问题


draw_text(screen, 48, "知识竞赛", 180, 20)
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
    tips = "当前一共有" + str(len(questionList)) + "个问题,目前是第" + str(index) + "个。"
    draw_text(screen, 18, tips, 20, 140, bg_color=WHITE, text_color=BLACK)
    current_que = questionList[index - 1]
    question_main = "问题" + str(index) + ". " + current_que.question
    draw_text(screen, 16, question_main, 20, 200, bg_color=WHITE, text_color=BLACK)
    for i in range(len(current_que.answer_question)):
        option = str(i + 1) + ". " + current_que.answer_question[i]
        draw_text(screen, 16, option, 40, 260 + i * 40, bg_color=WHITE, text_color=BLACK)

    pygame.display.update()

这样就实现了问题的显示

回答问题

首先我们给出提示，为了方便确认问题是否回答，答案正确与否，我们在问题类中添加变量


    # 是否回答
    answeredFlg = False

    # 回答是否正确
    rightFlg = False

根据这些变量设置文字。


    if current_que.answeredFlg:
        if current_que.rightFlg:
            print("回答正确，是" + current_que.answer_question[current_que.answer_index])
        else:
            print("回答错误，正确答案是" + current_que.answer_question[current_que.answer_index])
    else:
        draw_text(screen, 16, "请按下1、2、3、4来回答答案", 40, 460, bg_color=WHITE, text_color=RED)

如果按下按键，根据答案的正确与否给与响应的提示。


 if current_que.answeredFlg:
        if current_que.rightFlg:
            str1 = "回答正确，是" + current_que.answer_question[current_que.answer_index - 1]
            draw_text(screen, 16, str1, 40, 460, bg_color=WHITE, text_color=GREEN)
        else:
            str1 = "回答错误，正确答案是" + current_que.answer_question[current_que.answer_index - 1]
            draw_text(screen, 16, str1, 40, 460, bg_color=WHITE, text_color=RED)
    else:
        draw_text(screen, 16, "请按下1、2、3、4来回答答案", 40, 460, bg_color=WHITE, text_color=RED)

问题切换

为了方便用户切换问题，在窗口上添加对应的按钮。


import pygame.font


class Button:

    def __init__(self, screen, msg, start_x, start_y):
        # 设置按钮的尺寸和其他属性
        self.screen = screen
        self.width, self.height = 200, 50
        self.button_color = (0, 255, 0)
        self.text_color = (255, 255, 255)
        self.font = pygame.font.SysFont("方正粗黑宋简体", 20)

        # 创建按钮的rect对象，并使其居中
        self.rect = pygame.Rect(0, 0, self.width, self.height)
        self.rect.left = start_x
        self.rect.right = start_y
        # 按钮的标签只需创建一次
        self._prep_msg(msg)

    def _prep_msg(self, msg):
        """将msg渲染为图像，并让按钮居上"""
        self.msg_image = self.font.render(msg, True, self.text_color, self.button_color)
        self.msg_image_rect = self.msg_image.get_rect()
        self.msg_image_rect.center = self.rect.center

    def draw_button(self):
        # 绘制一个用颜色填充的按钮，在绘制文本
        self.screen.fill(self.button_color, self.rect)
        self.screen.blit(self.msg_image, self.msg_image_rect)

answer_question.py


	btn1 = Button(screen, "next", 300, 500)
    btn1.draw_button()

修改对应的按钮颜色，并添加上一个按钮。

通过是否回答和是否有下一个或者上一个控制按钮的显示


    if current_que.answeredFlg and index < len(questionList):
        btn1 = Button(screen, "下一个", 300, 500)
        btn1.draw_button()
    if index > 1:
        btn2 = Button(screen, "上一个", 50, 500)
        btn2.draw_button()

给按钮添加事件


        if event.type == pygame.MOUSEBUTTONDOWN:
            mouse_pos = pygame.mouse.get_pos()
            if btn1.rect.collidepoint(mouse_pos):
                if current_que.answeredFlg and index < len(questionList):
                    index += 1
            if btn2.rect.collidepoint(mouse_pos) and index > 1:
                index -= 1
