Python实现春节烟花效果
就快要过年了！！！很多小伙伴已经和朋友约好一起放烟花了，但是现在很多地方都禁止烟花燃放，过年没有烟花总感觉缺少一点味道~为了实现在家和朋友看烟花的愿望~这篇文章给大家带来2024过年烟花代码，让大家都能在家和朋友一起看自己编写的烟花，快快收藏起来吧！
用tkinter写的python烟花效果
今天给你们带来了用tkinter写的python烟花效果，点击鼠标即可触发。
完整实例
import tkinter as tk
import random
# 定义随机颜色函数
def random_color():
r = random.randint(0, 255)
g = random.randint(0, 255)
b = random.randint(0, 255)
return f'#{r:02x}{g:02x}{b:02x}'
# 定义烟花类
class Firework:
def __init__(self, canvas, x, y):
self.canvas = canvas
self.x = x
self.y = y
self.color = random_color()
self.radius = 2
self.particles = []
self.create_particles()
self.lifespan = 100 # 设置烟花消失的时间
# 创建粒子效果
def create_particles(self):
for i in range(120):
vx = random.uniform(-1, 1) * 8
vy = random.uniform(-1, 1) * 8
particle = self.canvas.create_oval(self.x, self.y, self.x+self.radius, self.y+self.radius, fill=self.color)
self.particles.append((particle, vx, vy))
# 更新烟花效果
def update(self):
self.radius += 0.5
self.lifespan -= 1
for particle in self.particles:
self.canvas.move(particle[0], particle[1], particle[2])
particle_position = self.canvas.coords(particle[0])
# 删除飞出屏幕的粒子
if particle_position[0] < 0 or particle_position[1] < 0 or particle_position[2] > 800 or particle_position[3] > 600:
self.canvas.delete(particle[0])
self.particles.remove(particle)
# 删除所有粒子后删除烟花
if not self.particles or self.lifespan <= 0:
self.canvas.delete(self.firework_id)
# 启动烟花效果
def fire(self):
self.firework_id = self.canvas.create_oval(self.x, self.y, self.x+self.radius, self.y+self.radius, fill=self.color)
self.canvas.after(10, self.launch)
# 发射烟花
def launch(self):
self.update()
if self.particles:
self.canvas.after(10, self.launch)
# 创建Tkinter窗口
root = tk.Tk()
root.geometry('800x600')
# 创建画布
canvas = tk.Canvas(root, bg='black')
canvas.pack(fill=tk.BOTH, expand=1)
# 点击事件处理函数
def on_click(event):
x = event.x
y = event.y
firework = Firework(canvas, x, y)
firework.fire()
# 绑定点击事件
canvas.bind('<Button-1>', on_click)
# 启动Tkinter事件循环
root.mainloop()3D旋转烟花
给大家带来了3D旋转烟花，这是一段Python代码，大家直接使用浏览器打开即可观看烟花，非常方便，并且效果也非常炫酷
