让pygame在用户点击的任何地方绘制立方体

import pygame
from pygame.locals import *

pygame.init()

screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("绘制立方体")

cube_size = 100
cube_color = (255, 0, 0)  # 立方体的颜色为红色

running = True
while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False
        elif event.type == MOUSEBUTTONDOWN:
            # 获取用户点击的位置
            mouse_x, mouse_y = pygame.mouse.get_pos()
            # 计算立方体的左上角坐标
            cube_x = mouse_x - cube_size / 2
            cube_y = mouse_y - cube_size / 2
            # 绘制立方体
            pygame.draw.rect(screen, cube_color, (cube_x, cube_y, cube_size, cube_size))
    
    pygame.display.update()
