如何在pymunk中制作一个静态的矩形？

import pymunk
import pygame

space = pymunk.Space()

body = pymunk.Body(body_type=pymunk.Body.STATIC)

width = 100  # 矩形宽度
height = 50  # 矩形高度
rect_shape = pymunk.Poly.create_box(body, (width, height))

x = 200  # 矩形中心点的x坐标
y = 200  # 矩形中心点的y坐标
rect_shape.body.position = x, y
angle = 0  # 矩形的旋转角度（弧度）
rect_shape.body.angle = angle

space.add(rect_shape)

width = 800  # 窗口宽度
height = 600  # 窗口高度
pygame.init()
screen = pygame.display.set_mode((width, height))
clock = pygame.time.Clock()

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

    screen.fill((255, 255, 255))
    
    # 更新物理空间中的物体状态
    space.step(1/60)
    
    # 绘制矩形
    for shape in space.shapes:
        vertices = shape.get_vertices()
        vertices = [(v.x, v.y) for v in vertices]
        pygame.draw.polygon(screen, (0, 0, 0), vertices)

    pygame.display.flip()
    clock.tick(60)

pygame.quit()
