【问题描述】：

我现在正在 pygame 中为一门课程创建 Battleship，我正在尝试超越，因为我喜欢使用 python 并用它用 pygame 创建东西。无论如何，我创建了一个 Button 类，它工作得很好，除了一个问题，如果我在屏幕上有多个按钮，它们都运行相同的代码：/ 我需要它们是唯一的，并且在它们被点击时运行不同的代码我似乎无法完成，哈哈。

这里是按钮类：

import pygame

red = (255, 0, 0)
darkRed = (153, 0, 0)
green = (0, 204, 0)
darkGreen = (0, 102, 0)
black = (0, 0, 0)
white = (255, 255, 255)
gray = (192, 192, 192)
darkGray = (96, 96, 96)


class Button(pygame.sprite.Sprite):

def __init__(self, color, color2, value):
    pygame.sprite.Sprite.__init__(self)
    self.color = color
    self.color2 = color2
    self.value = value

    self.image = pygame.Surface([80, 50])
    self.image.fill(self.color)

    self.rect = self.image.get_rect()

def update(self):
    pos = pygame.mouse.get_pos()

    xPos = self.rect[0]
    yPos = self.rect[1]
    width = self.rect[2]
    height = self.rect[3]

    if xPos + width > pos[0] > xPos and yPos + height > pos[1] > yPos:
        self.image.fill(self.color2)

    else:
        self.image.fill(self.color)

def click(self):
    click = pygame.mouse.get_pressed()

    if click[0] == True:
        return self.value

    else:
        return False

下面是运行一切的主要代码：

from Button import *
from TextDisplay import *
from wallPositions import *

screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))


def screen0():
pygame.init()

button_list = pygame.sprite.Group()

button = Button(green, darkGreen, True)
button_list.add(button)

text = Text("Battleship", white, 115, (screen_width * .5), (screen_height * .5 - 50))

done = False

clock = pygame.time.Clock()

button.rect.x = (screen_width * .5 - 35)
button.rect.y = (screen_height * .5 + 70)

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

        if button.click() == True:
            screen1()

        button_list.update()

    screen.fill(black)

    text.draw(screen)

    button_list.draw(screen)

    pygame.display.flip()

    clock.tick(30)

pygame.quit()

我一整天都被困在这个问题上，我问了我的老师，他说因为我在做一些不同的事情，我必须自己弄清楚，我什至问了学校的技术人员，他们都不知道：/我已经在堆栈中查看了大约一个小时，似乎没有人遇到与我相同的问题...请帮助，如果我的代码似乎有任何缩进问题，那是因为我只是复制并粘贴了它.

【问题讨论】：

button.click() 只运行第一个按钮的点击功能。所以我不确定你的问题是什么？顺便说一句，你做错了。您应该在事件循环中检查鼠标单击事件，然后再检查是否单击了任何按钮。
我只有一个 button.click() 因为当按下任何按钮时，它会运行那个按钮，而不仅仅是第一个按钮。但我会改为在事件循环中进行检查，看看是否可行，谢谢：p
还有一件事，现在您的代码不会检查是否单击了实际按钮。你只检查鼠标是否被点击。 Pygame 矩形有一个碰撞点函数，您可以使用它来检查一个点是否在矩形内。会派上用场的。
感谢您的帮助，当我看到您指出我在额头上打了自己的耳光时又好又重哈哈。我能够修复它，再次感谢您。

【解决方案1】：

在您的主程序中，编写 2 个按钮函数（func1 ()、func2 ()）。然后将一个变量添加到您的按钮类“self.action”和一个方法“def setaction（函数）。创建按钮时，请使用正确的函数调用方法：button.setaction (func1)。然后在时钟代码上你就可以'self.action'来调用相应的函数了。
