用pygame绘制一个可旋转的立方体

好的，以下是用pygame绘制一个可旋转的立方体的步骤：

1. 导入pygame模块

import pygame

2. 初始化pygame

pygame.init()

3. 设置窗口大小和标题

size = (640, 480)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("旋转的立方体")

4. 定义立方体的顶点坐标和面

vertices = [(100,100,100), (100,-100,100), (-100,-100,100), (-100,100,100), (100,100,-100), (100,-100,-100), (-100,-100,-100), (-100,100,-100)]
faces = [(0,1,2,3), (0,4,5,1), (1,5,6,2), (2,6,7,3), (0,3,7,4), (4,7,6,5)]

5. 定义旋转角度和旋转中心

angle = 0
center = (size[0]/2, size[1]/2)

6. 定义旋转函数

def rotate_point(point, angle):
    x = point[0]
    y = point[1]
    z = point[2]
    cos_a = pygame.math.cos(angle)
    sin_a = pygame.math.sin(angle)
    new_x = x * cos_a - y * sin_a
    new_y = x * sin_a + y * cos_a
    new_z = z
    return (new_x, new_y, new_z)

7. 定义绘制函数

def draw_cube(vertices, faces, angle):
    for face in faces:
        pointlist = []
        for i in face:
            point = vertices[i]
            point = rotate_point(point, angle)
            x = point[0] + center[0]
            y = point[1] + center[1]
            pointlist.append((x, y))
        pygame.draw.polygon(screen, (255,255,255), pointlist)

8. 进入游戏循环，不断旋转并绘制立方体

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
    screen.fill((0,0,0))
    draw_cube(vertices, faces, angle)
    angle += 0.01
    pygame.display.flip()

以上就是用pygame绘制一个可旋转的立方体的完整代码。
