如何在Pygame中创建级别系统？

Question

我正在制作一个简单的数学游戏，其中有5个问题的设定顺序。我目前仅将前两个问题作为功能以及基于玩家答案所调用的“胜利”和“损失”功能实现。但是，我无法弄清楚如何建立适当的级别系统。这是我实施的四个函数的当前代码：

def victory():
    global num_correct
    global time

    while True:
        screen.fill((150, 200, 255))

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        victory_text = font.render("Correct!", True, dark_blue)

        time -= 1
        timer.tick(100)
        if time <= 0:
            second_problem()

        score_display(30, 25)
        screen.blit(victory_text, (325, 240))
        pygame.display.update()

# when incorrect answer is chosen, call this function 
def loss():
    global num_correct
    global time

    while True:
        screen.fill((150, 200, 255))

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        loss_text = font.render("Incorrect!", True, dark_blue)

        time -= 1
        timer.tick(100)
        if time <= 0:
            second_problem()

        score_display(30, 25)
        screen.blit(loss_text, (310, 240))
        pygame.display.update()

# first math problem (9 - 6) + 3 = 6
def first_problem():
    global num_correct

    while True:
        screen.fill((150, 200, 255))

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        gametext = font.render("(9 - 6) + 3 = ", True, dark_blue)
        if six.draw(screen):
            print("true")
            num_correct += 1
            victory()

        if eight.draw(screen):
            print("false")
            loss()

        score_display(30, 25)
        screen.blit(gametext, (290, 75))
        pygame.display.update()

# second math problem 3 + (4 * 1) = 7
def second_problem():
    global num_correct

    while True:
        screen.fill((150, 200, 255))

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        gametext = font.render("3 + (4 * 1) = ", True, dark_blue)
        if seven.draw(screen):
            print("true")
            num_correct += 1
            victory()

        if nine.draw(screen):
            print("false")
            loss()

        score_display(30, 25)
        screen.blit(gametext, (290, 75))
        pygame.display.update()

当前“胜利”和“损失”仅涉及第二个问题。我计划总共实施5个。如何创建一个级别的系统来调用设定顺序的问题？

Answer 1

您可以减少代码。而不是first_problem（）和second_problem（）您可以使用一个具有不同值的函数

problem("3 + (4 * 1) = ", "7", "9")
problem("(9 - 6) + 3 = ", "6", "9")

，并且函数应返回 true 或false代码>代替运行victor（）或lose（）

，然后您可以将值保留在列表上，并使用 loop - loop，

all_problems =  [
    # (question, answer1, answer2)
    ("(9 - 6) + 3 = ", "6", "9"),
    ("3 + (4 * 1) = ", "7", "9"),
]

score = 0

for data in all_problems:
    result = problem(*data)
    if result:
        score += 1
        victory()
    else:
        loss()
        break   # exit when wrong answer

您将减少<<。代码> victor（）和lose（）带有参数消息（'corment！'），message（'Corrent！'），然后您可以进行

all_problems =  [
    # (question, answer1, answer2)
    ("(9 - 6) + 3 = ", "6", "9"),
    ("3 + (4 * 1) = ", "7", "9"),
]

score = 0

for data in all_problems:
    result = problem(*data)
    if result:
        score += 1
        message('Corrent!')
    else:
        message('Incorrent!')
        break   # exit when wrong answer

# - end -

message(f"Final Result: {score}")
