Pygame:在圆形路径中围绕另一个图像移动图像

import pygame
import math

pygame.init()
width, height = 800, 600
screen = pygame.display.set_mode((width, height))

image = pygame.image.load("image.png")
image_width, image_height = image.get_width(), image.get_height()

center_x, center_y = width // 2, height // 2  # 圆心坐标
radius = 200  # 圆的半径
angle = 0  # 初始角度
angular_speed = 0.1  # 角速度

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 清空屏幕
    screen.fill((0, 0, 0))

    # 计算图像在圆形路径上的位置
    x = center_x + math.cos(angle) * radius - image_width // 2
    y = center_y + math.sin(angle) * radius - image_height // 2

    # 绘制图像
    screen.blit(image, (x, y))

    # 更新角度
    angle += angular_speed

    # 更新显示
    pygame.display.flip()

pygame.quit()
