Python實現問題回答小遊戲

Posted on 2021-12-10 by WalkonNet

讀取問題

如下所示，我們在文本中寫瞭一個問題，然後將其讀取出來。

“黃河遠上白雲間，一片孤城萬仞山。”的作者是誰？

王之渙

李白

白居易

杜甫

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

運行之後發現報錯，查詢之後發現編碼格式不正確。

設置瞭讀取的編碼格式發現可以讀取文本的內容

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

繪制回答面板

為瞭方便讀取，新建一個類來儲存文件中的問題

# 問題類
class Question:

    # 回答列表
    answer_question = []

    # 正確答案
    answer_index = 1

    """問題類"""
    def __init__(self, question):
        self.question = question

導入問題，將文件中的問題保存在qustion中

from question import Question

因為文件的格式是固定的以6為一個問題的所有行數。

將問題

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)

封裝屏幕上顯示文字的打印

def draw_text(window_screen, font_size, content, starting_x, starting_y, text_color=WHITE, bg_color=BLACK):
    # 繪制文字
    # 設置字體
    font = pygame.font.SysFont("方正粗黑宋簡體", font_size)
    text1 = font.render(content, True, text_color, bg_color)
    window_screen.blit(text1, (starting_x, starting_y))

顯示問題

draw_text(screen, 48, "知識競賽", 180, 20)
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
    tips = "當前一共有" + str(len(questionList)) + "個問題,目前是第" + str(index) + "個。"
    draw_text(screen, 18, tips, 20, 140, bg_color=WHITE, text_color=BLACK)
    current_que = questionList[index - 1]
    question_main = "問題" + 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()

這樣就實現瞭問題的顯示

回答問題

首先我們給出提示，為瞭方便確認問題是否回答，答案正確與否，我們在問題類中添加變量

    # 是否回答
    answeredFlg = False

    # 回答是否正確
    rightFlg = False

根據這些變量設置文字。

    if current_que.answeredFlg:
        if current_que.rightFlg:
            print("回答正確，是" + current_que.answer_question[current_que.answer_index])
        else:
            print("回答錯誤，正確答案是" + current_que.answer_question[current_que.answer_index])
    else:
        draw_text(screen, 16, "請按下1、2、3、4來回答答案", 40, 460, bg_color=WHITE, text_color=RED)

如果按下按鍵，根據答案的正確與否給與響應的提示。

 if current_que.answeredFlg:
        if current_que.rightFlg:
            str1 = "回答正確，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 = "回答錯誤，正確答案是" + 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, "請按下1、2、3、4來回答答案", 40, 460, bg_color=WHITE, text_color=RED)

問題切換

為瞭方便用戶切換問題，在窗口上添加對應的按鈕。

import pygame.font


class Button:

    def __init__(self, screen, msg, start_x, start_y):
        # 設置按鈕的尺寸和其他屬性
        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("方正粗黑宋簡體", 20)

        # 創建按鈕的rect對象，並使其居中
        self.rect = pygame.Rect(0, 0, self.width, self.height)
        self.rect.left = start_x
        self.rect.right = start_y
        # 按鈕的標簽隻需創建一次
        self._prep_msg(msg)

    def _prep_msg(self, msg):
        """將msg渲染為圖像，並讓按鈕居上"""
        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):
        # 繪制一個用顏色填充的按鈕，在繪制文本
        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()

修改對應的按鈕顏色，並添加上一個按鈕。

通過是否回答和是否有下一個或者上一個控制按鈕的顯示

    if current_que.answeredFlg and index < len(questionList):
        btn1 = Button(screen, "下一個", 300, 500)
        btn1.draw_button()
    if index > 1:
        btn2 = Button(screen, "上一個", 50, 500)
        btn2.draw_button()

給按鈕添加事件

        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
