Pygame类菜单

Question

我以为我会试试pygame并且遇到了一个我希望有人可以帮助我的问题。我想有一个类def来创建退出按钮，但是当我这样做时，我无法让鼠标碰撞。我很可能做错了，但我真的很感激帮助。

它在我下面的状态下工作，但是当我把它放在def中时没有！

pygame.init()


class Window:

    def __init__(self):
        self.screen_width = 800
        self.screen_height = 600
        self.screen = (pygame.display.set_mode((self.screen_width, self.screen_height)))
        self.FPS = 30
        self.clock = pygame.time.Clock()
        self.font = pygame.font.SysFont('Arial', 25)
        self.menu_open = True
        self.colors = {"red": (255, 0, 0),
                       "green": (0, 255, 0),
                       "blue": (0, 0, 255),
                       "white": (255, 255, 255),
                       "black": (0, 0, 0),
                       "brown": (153, 76, 0),
                       "grey": (100, 100, 100)}

    def setup(self):
        self.screen.fill(self.colors["black"])
        pygame.display.set_caption("Menu Test!")

    def text(self, message, text_color, x_pos, y_pos):
        text = self.font.render(message, True, (self.colors[text_color]))
        text_rect = text.get_rect(center=(x_pos, y_pos))
        self.screen.blit(text, text_rect)

    def exit(self):
        self.screen.fill(self.colors["black"])
        text = self.font.render("Thank you for playing. Goodbye!", True,
                                (self.colors["white"]))
        text_rect = text.get_rect(center=(self.screen_width / 2,
                                          self.screen_height / 2))
        self.screen.blit(text, text_rect)
        pygame.display.update()
        sleep(3)
        pygame.quit()
        sys.exit()


def main():
    window = Window()
    window.setup()

这是我想要的一个类def

    quit_button = pygame.draw.rect(window.screen, window.colors["white"],
                                   (window.screen_width / 2 - 100,
                                    window.screen_height / 1.5 - 25, 200, 50), 0)
    window.text("QUIT", "red", window.screen_width / 2, window.screen_height / 1.5)
    pygame.display.update()

    while window.menu_open == 1:
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()

这就是它在矩形上点击鼠标的位置。

            if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
                pos = pygame.mouse.get_pos()
                if quit_button.collidepoint(pos):
                    window.exit()
                else:
                    print("Error Line 48")

if __name__ == "__main__":
    main()

Answer 1

使用import re c=r"([0-9]{1,2}\s+)(2003-09-07).+(2006-12-25)\s+\w+" with open("event.txt","r") as f: file_data=f.readlines() regex_search=re.search(c,str(file_data)) print(regex_search.group()) 和pygame.sprite.Sprite属性创建一个类（在本例中我使用image子类）并将文本blit到图像上。

rect

更高级的解决方案是处理import sys import pygame as pg pg.init() class Window: def __init__(self): self.screen = pg.display.set_mode((800, 600)) self.rect = self.screen.get_rect() self.FPS = 30 self.clock = pg.time.Clock() self.font = pg.font.SysFont("Arial", 25) self.menu_open = True self.colors = {"red": (255, 0, 0), "green": (0, 255, 0), "blue": (0, 0, 255), "white": (255, 255, 255), "black": (0, 0, 0), "brown": (153, 76, 0), "grey": (100, 100, 100)} def setup(self): self.screen.fill(self.colors["black"]) pg.display.set_caption("Menu Test!") def text(self, message, text_color, x_pos, y_pos): text = self.font.render(message, True, (self.colors[text_color])) text_rect = text.get_rect(center=(x_pos, y_pos)) self.screen.blit(text, text_rect) def exit(self): self.screen.fill(self.colors["black"]) text = self.font.render("Thank you for playing. Goodbye!", True, (self.colors["white"])) text_rect = text.get_rect(center=(self.rect.w/2, self.rect.h/2)) self.screen.blit(text, text_rect) pg.display.update() pg.time.wait(1000) pg.quit() sys.exit() class Button(pg.sprite.Sprite): def __init__(self, pos, text, window): super().__init__() # Call __init__ of the parent class. # Render the text. self.text_surf = window.font.render(text, True, window.colors["black"]) self.image = pg.Surface((self.text_surf.get_width()+40, self.text_surf.get_height()+20)) self.image.fill(window.colors["white"]) # Now blit the text onto the self.image. self.image.blit(self.text_surf, (20, 10)) self.rect = self.image.get_rect(topleft=pos) def main(): window = Window() window.setup() clock = pg.time.Clock() # gui is a sprite group which will contain the button sprites. gui = pg.sprite.Group() # Instantiate some buttons. quit_button = Button( pos=(window.rect.w/2 - 100, window.rect.h/1.5 - 25), text="QUIT", window=window, ) hello_button = Button( pos=(window.rect.w/8, window.rect.h/2), text="hello", window=window, ) # Add the buttons to the gui group. gui.add(quit_button, hello_button) while window.menu_open == True: for event in pg.event.get(): if event.type == pg.QUIT: window.exit() if event.type == pg.MOUSEBUTTONDOWN and event.button == 1: # Handle button events. if quit_button.rect.collidepoint(event.pos): window.exit() elif hello_button.rect.collidepoint(event.pos): print("hello") gui.update() # Call update methods of contained sprites. gui.draw(window.screen) # Draw all sprites. pg.display.flip() clock.tick(30) if __name__ == "__main__": main() 类中的事件，然后调用在实例化期间必须传递的回调函数。
