同款爱心Python代码版来了-编程知识

同款爱心就是一个动态的♥型效果，主要 Python 代码实现如下：

def __init__(self, generate_frame=20):
# 原始爱心坐标集合
self._points = set()  
# 边缘扩散效果点坐标集合
self._edge_diffusion_points = set()  
# 中心扩散效果点坐标集合
self._center_diffusion_points = set()  
# 每帧动态点坐标
self.all_points = {}  
self.build(2000)
self.random_halo = 1000
self.generate_frame = generate_frame
for frame in range(generate_frame):self.calc(frame)def build(self, number):
for _ in range(number):t = random.uniform(0, 2 * pi)x, y = heart(t)self._points.add((x, y))
# 爱心内扩散
for _x, _y in list(self._points):for _ in range(3):x, y = scatter_inside(_x, _y, 0.05)self._edge_diffusion_points.add((x, y))
# 爱心内再次扩散
point_list = list(self._points)
for _ in range(4000):x, y = random.choice(point_list)x, y = scatter_inside(x, y, 0.17)self._center_diffusion_points.add((x, y))@staticmethodstaticmethod
def calc_position(x, y, ratio):
force = 1 / (((x - X) ** 2 +(y - Y) ** 2) ** 0.520)
dx = ratio * force * (x - X) + random.randint(-1, 1)
dy = ratio * force * (y - Y) + random.randint(-1, 1)
return x - dx, y - dydef calc(self, generate_frame):
ratio = 10 * curve(generate_frame / 10 * pi)
halo_radius = int(4 + 6 * (1 + curve(generate_frame / 10 * pi)))
halo_number = int(3000 + 4000 * abs(curve(generate_frame / 10 * pi) ** 2))
all_points = []
# 光环
heart_halo_point = set()
for _ in range(halo_number):t = random.uniform(0, 2 * pi)x, y = heart(t, shrink_ratio=11.6)x, y = shrink(x, y, halo_radius)if (x, y) not in heart_halo_point:heart_halo_point.add((x, y))x += random.randint(-14, 14)y += random.randint(-14, 14)size = random.choice((1, 2, 2))all_points.append((x, y, size))
# 轮廓
for x, y in self._points:x, y = self.calc_position(x, y, ratio)size = random.randint(1, 3)all_points.append((x, y, size))
# 内容
for x, y in self._edge_diffusion_points:x, y = self.calc_position(x, y, ratio)size = random.randint(1, 2)all_points.append((x, y, size))
self.all_points[generate_frame] = all_points
for x, y in self._center_diffusion_points:x, y = self.calc_position(x, y, ratio)size = random.randint(1, 2)all_points.append((x, y, size))
self.all_points[generate_frame] = all_points

实现效果如下：
