用Python制作一个李峋同款的动态爱心效果!
大家好,我是 Jack~
最近「点燃我,温暖你」这部剧非常火,讲述的是程序员的爱情故事。
其中陈飞宇饰演的男主李峋,在剧中用程序做出的爱心跳动效果,非常炫。
网上各个大佬也是纷纷给出看法,综合就是不太可能用C语言来实现的。
大概率是AE这种做特效软件实现的,毕竟里面的编程语言、编辑器、程序出现太多问题啦。
下面小F就给大家分享各个版本的跳动爱心,有兴趣的小伙伴可以去试试,送给那个人!
① Python跳动爱心
由B站UP主@码农高天原创,博客园@清风来叙魔改,我们来看看效果吧。
涉及到了不少数学知识,需定义曲线函数,然后去调整爱心跳动周期。
源代码如下,感兴趣的小伙伴可以去试试。
可玩的东西还是挺多的,比如改变颜色,添加字幕,打包成exe,然后发给别人。

② Python爱心泡泡
用Python做一个爱心泡泡机。
使用turtle海龟库进行绘制,代码如下。
import turtle
import random
import math
# 初始化
turtle.setup(1280, 720)
t = turtle.Pen()
t.ht()
# 颜色
colors = []
t_list = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f"]
for i in t_list:
t_str = "#ff00"
for j in t_list:
colors.append(t_str+i+j)
class Love():

# 定义变量
self.r = random.randint(4, 10)

self.speed = random.randint(1, 8)

# 通过y坐标来控制爱心
if self.y <= 500:
self.y += 2.5*self.speed
self.x = self.x + 1.5*math.sin(self.i)*math.sqrt(self.i)*self.speed
self.i = self.i + 0.1
else:
self.y = -700
self.r = random.randint(5, 20)
self.x = random.randint(-900, 700)
self.i = 0
self.color = random.choice(colors)
self.speed = random.randint(1, 8)
def draw(self):
# 绘制爱心
t.pensize(self.r/2)
t.penup()
t.color(self.color, self.color)
t.goto(self.x, self.y)
t.pendown()
# 设置角度
t.setheading(60)
t.circle(self.r, 255)
t.fd(2.4*self.r)
t.left(90)
t.fd(2.4*self.r)
t.circle(self.r, 255)
love = []
for i in range(100):
love.append(Love())
turtle.bgcolor("#000000")
while 1:
turtle.tracer(0)
t.clear()
for i in range(80):
love[i].move()
love[i].draw()

对于上面的网页最好是部署在服务器上,这样就能在互联网上进行访问。
可以通过一个centos系统服务器,用nginx又或者是httpd进行实现。
然后就可以把网站地址发出去啦!
