Pygame:如何对图像进行blit和旋转以连接屏幕上的两个点？

import pygame
import math

# 初始化Pygame
pygame.init()

# 设置屏幕尺寸
screen_width, screen_height = 800, 600
screen = pygame.display.set_mode((screen_width, screen_height))

# 加载图像
image = pygame.image.load('path_to_your_image.png')
image_rect = image.get_rect()

# 定义起始点和结束点
start_point = pygame.math.Vector2(100, 100)
end_point = pygame.math.Vector2(400, 300)

# 游戏主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 清屏
    screen.fill((255, 255, 255))

    # 计算旋转角度
    direction_vector = end_point - start_point
    angle = math.degrees(math.atan2(-direction_vector.y, direction_vector.x))

    # 旋转图像
    rotated_image = pygame.transform.rotate(image, angle)
    rotated_rect = rotated_image.get_rect(center=start_point)

    # 调整旋转后图像的位置
    rotated_rect.centerx += direction_vector.x
    rotated_rect.centery += direction_vector.y

    # 绘制旋转后的图像
    screen.blit(rotated_image, rotated_rect)

    # 更新屏幕显示
    pygame.display.flip()

# 退出Pygame
pygame.quit()
