在pygame中对22x16网格中的顶点进行正方形

import pygame
pygame.init()

screen_width = 800  # 屏幕宽度
screen_height = 600  # 屏幕高度
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("绘制正方形")

grid_width = 50  # 网格宽度
grid_height = 50  # 网格高度
num_rows = 16  # 网格行数
num_cols = 22  # 网格列数
vertex_color = (255, 0, 0)  # 顶点颜色，这里使用红色

def draw_square(row, col):
    x = col * grid_width  # 正方形左上角的x坐标
    y = row * grid_height  # 正方形左上角的y坐标
    rect = pygame.Rect(x, y, grid_width, grid_height)  # 创建一个矩形对象
    pygame.draw.rect(screen, vertex_color, rect)  # 在屏幕上绘制矩形

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    
    screen.fill((255, 255, 255))  # 清空屏幕
    
    # 绘制正方形
    for row in range(num_rows):
        for col in range(num_cols):
            draw_square(row, col)
    
    pygame.display.flip()  # 更新屏幕显示

pygame.quit()
