python小游戏源码

见缝插针小游戏，设置关卡，难度逐渐增大，效果图如下，需要的话去个人主页提取资源

部分代码如下：

def __init__(self, angle):
self.x = x0
self.y = y0 + length
self.center = (self.x, self.y)
self.radius = 12
self.angle = angle
ball_group.append(self)

def draw(self, surface):
pygame.draw.line(surface, WHITE, shaft, self.center, 2)
pygame.draw.circle(surface, WHITE, self.center, 12)

def move(self, speed):
"""
围绕转轴做圆周运动
:param speed: 转动的角速度
:return:
"""
if self.angle < 2 * math.pi:
self.angle += speed
else:
self.angle = self.angle - 2 * math.pi
self.x = x0 - length * math.sin(self.angle)
self.y = y0 + length * math.cos(self.angle)
self.center = (self.x, self.y)
