让 pygame 在继续之前等待用户点击/输入（python 问答游戏）

Question

所以我正在尝试在 pygame 上制作一个游戏，它将一个词汇表显示为一个问题和三个答案选项。如果用户按正确的答案，他们的分数会上升一，游戏将进入下一个词汇问题。

我将我的问题存储在一个名为 questions[] 的二维数组中，在数组的每个元素中，它将每个问题的问题和答案保存为 [问题、正确答案选择、答案选择、答案选择]。所以正确的答案总是在索引位置[i][1]。我确实随机化了稍后显示答案选择的顺序。

现在我的问题是我的游戏在不等待用户输入的情况下通过问题。关键是它会等待用户点击。当用户点击时，它会检查用户点击的位置。用户鼠标的位置将决定用户按下哪个“答案框”。让我们假设用户按下了第一个框。游戏然后比较存储在该框中的文本是否正确（即文本与 questions[i][1] 相同）。它会在瞬间显示每个问题，然后转到下一个问题和下一个问题。

但它不会等待用户先点击。甚至没有，它甚至没有显示足够长的时间让用户阅读问题。有没有办法可以构建循环或添加某些条件，以便程序显示每个问题，直到用户选择答案，然后添加分数并继续下一个问题？

代码如下：

import pygame
from random import randint
from pygame import *

pygame.init()
pygame.font.match_font('Courier New.ttf')


BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)
GREEN = (71, 212, 15)
BLUE = (42, 250, 246)
PINK = (255,102, 196)
YELLOW = (255, 255, 0)
i = 0

    if drawbox[0]+drawbox[2] > mouse[0] > drawbox[0] and drawbox[1]+drawbox[3] > mouse[1] > drawbox[1]:
        pygame.draw.rect(screen, drawbox[5],(drawbox[0],drawbox[1],drawbox[2],drawbox[3]),drawbox[6])           
    else:

    answerTextFont = pygame.font.SysFont("Courier New",60)
    textWord, textBox = textObject(drawbox[7], answerTextFont) #the text & the "Text box"
    textBox.center = ( (drawbox[0]+(drawbox[2]/2)), (drawbox[1]+(drawbox[3]/2)) )
    screen.blit(textWord, textBox)

def questionbutton(message,x,y,w,h,color):
    mouse = pygame.mouse.get_pos()
    pygame.draw.rect(screen,color,(x,y,w,h))

    answerTextFont = pygame.font.SysFont("Courier New",60)
    textWord, textBox = textObject(message, answerTextFont) #the text & the "Text box"
    textBox.center = ( (x+(w/2)), (y+(h/2)) )
    screen.blit(textWord, textBox)

while not done:

    text = font.render("SPACE VOCBULARY QUIZ",True,WHITE)
    screen.blit(text, [30, 30])
    font = pygame.font.SysFont('Courier', 30, False, False)
    text = font.render("SCORE: ", True, WHITE)
    screen.blit(text, [500, 30])

    for event in pygame.event.get():
        if i == (len(questions)): #if user clicks close then done becomes true and game quits
            done = True
            event.type == pygame.QUIT
        for c in range (len(questions)):

            questionbutton((questions[c][0]),30,150,640,100,GREEN)
            for n in range(3):
                choices.append(questions[c][n+1])
            for r in range(3):
                randomPointer = randint(0, (len(choices)-1))
                answerboxes[r].append(choices[randomPointer])
                choices.remove(choices[randomPointer])
                answerbutton(answerboxes[r][0:8])
            if click[0] == 1: 
                for a in range(3):
                    if answerboxes[a][0]+answerboxes[a][2] > mouse[0] > answerboxes[a][0] and answerboxes[a][1]+answerboxes[a][3] > mouse[1] > answerboxes[a][1]:
                        if answerboxes[a][7] == questions[i][1]:
                            score = score + 1
                            print (score)
            for g in range (3):
                answerboxes[g].pop()           
            i = i+1

pygame.quit()

Answer 1

你可以在问题的循环中设置一个无限循环，当鼠标点击答案框时退出无限循环的中断条件。

示例：

for c in len(range(questions)):
    clicked_on_answer = False
    while True:
        # your code

        if click[0] == 1: 
            for a in range(3):
                if answerboxes[a][0]+answerboxes[a][2] > mouse[0] > answerboxes[a][0] and answerboxes[a][1]+answerboxes[a][3] > mouse[1] > answerboxes[a][1]:
                    clicked_on_answer = True
                    if answerboxes[a][7] == questions[i][1]:
                        score = score + 1
                        print (score)
        if clicked_on_answer:
            break

是的，您需要重组程序并将绘图与事件处理和游戏逻辑更好地分开。如果按下鼠标按钮，它应该只进入下一个问题，所以检查事件循环if event.type == pygame.MOUSEBUTTONDOWN:（每次点击只产生一个MOUSEBUTTONDOWN事件），然后查看是否点击了矩形，增加分数，最后提出下一个问题和选择。 Blit 事件循环之外的问题和选择文本。

clock = pygame.time.Clock()  # A clock to limit the frame rate.
# Define the fonts outside of the main loop.
font = pygame.font.SysFont('Courier', 30, False, False)

# Render question and choice text surfaces.
# Create the rects for the choices and set their positions.

while not done:
    # Handle events.
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.MOUSEBUTTONDOWN:
            # Check if event.pos collides with the correct rect.
            for index, rect in enumerate(rects):
                if rect.collidepoint(event.pos) and choices[index] == correct_answer:
                    score += 1
            # Get next question and choices, render them and update the rects.

    # Draw everything.
    # Blit the question and choice text surfaces at their rects.

    pygame.display.update()
    clock.tick(30)  # Limit frame rate to 30 fps.
