pygame绘制梯形 使用polygon函数

points=[(100,30),(200,30),(250,130),(50,130)]
pygame.draw.polygon(screen, (0, 144, 0), points)
1
2

绘制顺序是从左上开始，右上，右下，左下

如果是左上，右上，左下，右下就会变成两个三角形

pygame.init()
screen = pygame.display.set_mode((640, 480), 0, 32)
points = []

            # add the position to points
            points.append(event.pos)
    # refresh the screen
    screen.fill((255,255,255))
    # draw the polygon
    if len(points) >= 3:
        pygame.draw.polygon(screen, (0,255,0), points)
    # draw the point
    for point in points:
        pygame.draw.circle(screen, (0,0,255), point, 5)
    # display on screen
    pygame.display.update()
