class firstpage: def __init__(self,screen): self.screen = screen self.font = pygame.font.Font("D:\Virtual stdio2022\华文行楷.ttf", 36) self.button1 = self.font.render("登录/注册", True, BLACK) self.button1_rect=self.button1.get

这段代码是一个 Python 类，名为 `firstpage`，它有一个 `__init__` 方法，接收一个 `screen` 参数。`screen` 可以是 Pygame 中的一个 `Surface` 对象，用于绘制游戏界面。在 `__init__` 方法中，首先通过指定字体文件路径创建了一个 `Font` 对象，用于在界面上显示文本。然后，通过该字体对象的 `render` 方法创建了一个名为 `button1` 的文本 Surface 对象，该文本为 "登录/注册"，颜色为 `BLACK`。最后，通过 `get` 方法获取了 `button1` 的矩形区域，保存在 `button1_rect` 中。这个矩形区域用于在屏幕上画出按钮。

import sys import pygame from yaya import YAYA class Sky: def __init__(self): self.screen=pygame.display.set_mode((0,0),pygame.FULLSCREEN) self.bg_color=(0,23,56) self.yaya=YAYA(self) def run_game(self): while True: for event in pygame.event.get(): if event.type==pygame.QUIT: sys.exit() self.screen.fill(self.bg_color) self.yaya.blitme() self.display.flip() if __name__=='__main__': blny=Sky() blny.run_game()

在你的代码中，你有一个`Sky`类，以及一个`run_game`方法。在`run_game`方法中，你调用了`self.display.flip()`。然而，`display`属性实际上不存在于`Sky`类中。相反，你应该使用`pygame.display.flip()`来刷新屏幕。

因此，你的代码应该修改为：

import sys
import pygame
from yaya import YAYA

class Sky:
    def __init__(self):
        self.screen=pygame.display.set_mode((0,0),pygame.FULLSCREEN)
        self.bg_color=(0,23,56)
        self.yaya=YAYA(self)

    def run_game(self):
        while True:
            for event in pygame.event.get():
                if event.type==pygame.QUIT:
                    sys.exit()
            self.screen.fill(self.bg_color)
            self.yaya.blitme()
            pygame.display.flip()

if __name__=='__main__':
    blny=Sky()
    blny.run_game()

这应该可以解决你遇到的问题。

帮我把下面代码添加注释class Button: def __init__(self, text='按钮', left=0, top=0, width=90, height=30, color=(200, 200, 200)): self.text = text self.color = color self.rect = pygame.Rect(left, top, width, height) self.font = pygame.font.Font(r"C:\Windows\Fonts\simsun.ttc", 16) self.text_surface = self.font.render(self.text, True, (0, 0, 0)) self.text_rect = self.text_surface.get_rect() # self.text_rect.center = self.rect.center self.active = False self.function = None button_group.append(self) def set_text(self, new_text): self.text = new_text self.text_surface = self.font.render(self.text, True, (0, 0, 0)) self.text_rect = self.text_surface.get_rect() def draw(self, screen): if self.active: pygame.draw.rect(screen, (180, 180, 200), self.rect, 0) else: pygame.draw.rect(screen, self.color, self.rect, 0) self.text_rect.center = self.rect.center screen.blit(self.text_surface, self.text_rect) def get_click(self, event): if event.type == pygame.MOUSEBUTTONDOWN: if event.button == 1: mx, my = event.pos if self.rect.left <= mx <= self.rect.right and self.rect.top <= my <= self.rect.bottom: self.active = True elif event.type == pygame.MOUSEBUTTONUP and self.active: if event.button == 1: mx, my = event.pos if self.rect.left <= mx <= self.rect.right and self.rect.top <= my <= self.rect.bottom: # print(f'{self.text}按钮被点击') if callable(self.function): self.function() self.active = False def click_connect(self, function): self.function = function
