含源码，用Python实现浪漫烟花( 二 ) _烟花

Trail：烟花轨迹，本质上是一个点。创建 Trail 类，定义 show 方法绘制轨迹、实时获取轨迹坐标
class Trail:def __init__(self, n, size, dynamic):self.pos_in_line = nself.pos = vector(-10, -10)self.dynamic = dynamicif self.dynamic:self.colour = trail_colours[n]self.size = int(size - n / 2)else:self.colour = (255, 255, 200)self.size = size - 2if self.size < 0:self.size = 0def get_pos(self, x, y):self.pos = vector(x, y)def show(self, win):pygame.draw.circle(win, self.colour, (int(self.pos.x), int(self.pos.y)), self.size)def update(win, fireworks):for fw in fireworks:fw.update(win)if fw.remove():fireworks.remove(fw)pygame.display.update()
主函数部分：

运行游戏：
if __name__ == 'main':main()
