好的,以下是一个使用pymunk设置旋转球体的示例代码:
```python
import pymunk
import pygame
pygame.init()
screen = pygame.display.set_mode((600, 600))
clock = pygame.time.Clock()
space = pymunk.Space()
space.gravity = (0, 1000)
ball_body = pymunk.Body(1, 1666)
ball_body.position = (300, 300)
ball_shape = pymunk.Circle(ball_body, 50)
ball_shape.elasticity = 0.95
space.add(ball_body, ball_shape)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
space.step(1/60)
screen.fill((255, 255, 255))
ball_pos = ball_body.position
ball_angle = ball_body.angle
ball_points = [(x, y) for x, y in ball_shape.get_vertices()]
ball_points = [(x, y) for x, y in pymunk.pygame_util.to_pygame(ball_points, screen)]
pygame.draw.polygon(screen, (0, 0, 255), ball_points)
pygame.draw.line(screen, (255, 0, 0), ball_pos, (ball_pos[0] + 50 * pymunk.vec2d.Vec2d(1, 0).rotated(ball_angle), ball_pos[1]))
pygame.display.update()
clock.tick(60)
```
这个示例代码创建了一个pymunk空间,并在其中添加了一个质量为1、半径为50的圆形刚体。在主循环中,我们使用pymunk计算物理模拟,并将球体的位置和旋转角度转换为pygame坐标系中的点和线段,然后在屏幕上绘制出来。
