'''

FIREWORKS SIMULATION WITH TKINTER

*self-containing code

*to run: simply type python simple.py in your console

*compatible with both Python 2 and Python 3

*Dependencies: tkinter, Pillow (only for background image)

*The design is based on high school physics, with some small twists only for aesthetics purpose

import tkinter as tk

#from tkinter import messagebox

#from tkinter import PhotoImage

from PIL import Image, ImageTk

from time import time, sleep

from random import choice, uniform, randint

from math import sin, cos, radians

# gravity, act as our constant g, you can experiment by changing it

GRAVITY = 0.05

# list of color, can choose randomly or use as a queue (FIFO)

colors = ['red', 'blue', 'yellow', 'white', 'green', 'orange', 'purple', 'seagreen','indigo', 'cornflowerblue']

Generic class for particles

particles are emitted almost randomly on the sky, forming a round of circle (a star) before falling and getting removed

from canvas

Attributes:

- id: identifier of a particular particle in a star

- x, y: x,y-coordinate of a star (point of explosion)

- vx, vy: speed of particle in x, y coordinate

- total: total number of particle in a star

- age: how long has the particle last on canvas

- color: self-explantory

- cv: canvas

- lifespan: how long a particle will last on canvas

class part:

def __init__(self, cv, idx, total, explosion_speed, x=0., y=0., vx = 0., vy = 0., size=2., color = 'red', lifespan = 2, **kwargs):

self.id = idx

self.x = x

self.y = y

self.initial_speed = explosion_speed

self.vx = vx

self.vy = vy

self.total = total

self.age = 0

self.color = color

self.cv = cv

self.cid = self.cv.create_oval(

x - size, y - size, x + size,

y + size, fill=self.color)

self.lifespan = lifespan

def update(self, dt):

self.age += dt

# particle expansions

if self.alive() and self.expand():

move_x = cos(radians(self.id*360/self.total))*self.initial_speed

move_y = sin(radians(self.id*360/self.total))*self.initial_speed

self.cv.move(self.cid, move_x, move_y)

self.vx = move_x/(float(dt)*1000)

# falling down in projectile motion

elif self.alive():

move_x = cos(radians(self.id*360/self.total))

# we technically don't need to update x, y because move will do the job

self.cv.move(self.cid, self.vx + move_x, self.vy+GRAVITY*dt)

self.vy += GRAVITY*dt

# remove article if it is over the lifespan

elif self.cid is not None:

cv.delete(self.cid)

self.cid = None

# define time frame for expansion

def expand (self):

return self.age <= 1.2

# check if particle is still alive in lifespan

def alive(self):

return self.age <= self.lifespan

Firework simulation loop:

Recursively call to repeatedly emit new fireworks on canvas

a list of list (list of stars, each of which is a list of particles)

is created and drawn on canvas at every call,

via update protocol inside each 'part' object

def simulate(cv):

t = time()

explode_points = []

wait_time = randint(10,100)

numb_explode = randint(6,10)

# create list of list of all particles in all simultaneous explosion

for point in range(numb_explode):

objects = []

x_cordi = randint(50,550)

y_cordi = randint(50, 150)

speed = uniform (0.5, 1.5)

size = uniform (0.5,3)

color = choice(colors)

explosion_speed = uniform(0.2, 1)

total_particles = randint(10,50)

for i in range(1,total_particles):

r = part(cv, idx = i, total = total_particles, explosion_speed = explosion_speed, x = x_cordi, y = y_cordi,

vx = speed, vy = speed, color=color, size = size, lifespan = uniform(0.6,1.75))

objects.append(r)

explode_points.append(objects)

total_time = .0

# keeps undate within a timeframe of 1.8 second

while total_time < 1.8:

sleep(0.01)

tnew = time()

t, dt = tnew, tnew - t

for point in explode_points:

for item in point:

item.update(dt)

cv.update()

total_time += dt

# recursive call to continue adding new explosion on canvas

root.after(wait_time, simulate, cv)

def close(*ignore):

"""Stops simulation loop and closes the window."""

global root

root.quit()

if __name__ == '__main__':

root = tk.Tk()

cv = tk.Canvas(root, height=600, width=600)

# use a nice background image

image = Image.open("./image1.jpg")#背景照片路径自行选择,可以选择酷炫一点的,看起来效果会#更好

photo = ImageTk.PhotoImage(image)

cv.create_image(0, 0, image=photo, anchor='nw')

cv.pack()

root.protocol("WM_DELETE_WINDOW", close)

root.after(100, simulate, cv)

root.mainloop()

注意:这里需要安装tkinter,安装过程:

step1:

>>> import _tkinter # with underscore, and lowercase 't'

step2:

>>> import Tkinter # no underscore, uppercase 'T' for versions prior to V3.0

>>> import tkinter # no underscore, lowercase 't' for V3.0 and later

step3:

>>> Tkinter._test() # note underscore in _test and uppercase 'T' for versions prior to V3.0

>>> tkinter._test() # note underscore in _test and lowercase 'T' for V3.0 and later

然后就可以运行了,在代码中有一个背景照片部分,路径可自行选择!我这里就不修改了。

<think>好的,我现在需要处理用户关于Python烟花特效表白程序的请求。首先,用户希望得到用Python实现的烟花特效源代码示例,并且之前他们提供的参考引用中有一些相关的信息,我需要整合这些信息来生成一个合适的回答。 首先,我应该检查用户提供的引用内容。引用[1]提到有PythonHTML烟花特效代码,但用户主要关注Python部分。引用[2]详细描述了一个使用自定义Fireworks类管理烟花状态和动画的示例,包括烟花上升、变大和粒子效果。引用[3]和[4]则提到了简单的烟花效果,并指出可以通过添加更多功能来增强效果,还提到使用turtle模块的可能性。 用户的需求是寻找一个表白特效,所以需要结合动画效果和文字显示。考虑到引用[2]中的Fireworks类,可能适合使用pygame库来实现,因为pygame适合处理更复杂的动画和粒子效果。而引用[4]提到turtle模块,但可能速度较慢,所以可能更适合简单效果,但用户需要的,所以pygame更合适。 接下来,我需要确保代码示例的正确性。根据引用[2],Fireworks类管理烟花的位置、大小和状态。烟花上升到一定高度后消失并重新生成,同时生成粒子效果。此外,用户需要表白文字,所以应该在烟花爆炸时显示文字。 需要整合这些元素:初始化pygame,设置屏幕,创建烟花粒子,处理事件循环,更新粒子状态,绘制到屏幕。可能包括多个烟花实例,每个有自己的位置、颜色、爆炸效果等。在爆炸时显示“I Love You”之类的文字。 需要注意代码结构是否清晰,比如类设计,粒子系统的管理,颜色和速度的随机生成。同时,确保代码没有语法错误,比如正确的缩进、函数调用等。 然后,根据用户的要求,生成相关问题。可能涉及如何调整颜色、速度,如何添加音乐,优化性能,或结合其他库如tkinter做界面。 最后,确保回答符合系统级指令:行内数学公式用$...$,独立公式用$$...$$,但在这个问题中可能用不到数学公式。使用中文,结构清晰,引用正确,每个引用在相关部分末尾添加标识符。 现在,将这些思路整合成一个代码示例,并解释关键部分,确保引用来源正确标注。同时生成相关问题,帮助用户进一步探索。</think>以下是一个基于Python烟花特效表白程序示例,结合了粒子动画和文字显示效果。代码基于pygame库实现,参考了站内多个烟花特效实现方案并进行了优化[^2][^3][^4]: ```python import pygame import random import math # 初始化pygame pygame.init() screen = pygame.display.set_mode((800, 600)) clock = pygame.time.Clock() class Particle: def __init__(self, pos, color): self.pos = list(pos) self.color = color self.velocity = [ random.uniform(-3, 3), random.uniform(-8, -4) ] self.age = 0 def update(self): self.velocity[1] += 0.2 # 重力加速度 self.pos[0] += self.velocity[0] self.pos[1] += self.velocity[1] self.age += 1 class Firework: def __init__(self): self.reset() self.particles = [] self.exploded = False def reset(self): self.x = random.randint(100, 700) self.y = 600 self.color = ( random.randint(100, 255), random.randint(100, 255), random.randint(100, 255) ) self.speed = random.uniform(3, 7) self.exploded = False def update(self): if not self.exploded: self.y -= self.speed if self.speed > 0.5: self.speed -= 0.02 if self.speed <= 0.5: self.explode() for p in self.particles[:]: p.update() if p.age > 50: self.particles.remove(p) if len(self.particles) == 0 and self.exploded: self.reset() def explode(self): for _ in range(50): # 爆炸粒子数 self.particles.append(Particle((self.x, self.y), self.color)) self.exploded = True def draw_text(): font = pygame.font.SysFont('arial', 64) text = font.render('I Love You!', True, (255, 215, 0)) text_rect = text.get_rect(center=(400, 300)) screen.blit(text, text_rect) fireworks = [Firework() for _ in range(3)] # 同时存在的烟花数量 running = True while running: screen.fill((0, 0, 0)) for event in pygame.event.get(): if event.type == pygame.QUIT: running = False for fw in fireworks: fw.update() for p in fw.particles: pygame.draw.circle(screen, p.color, (int(p.pos[0]), int(p.pos[1])), 3) draw_text() # 绘制表白文字 pygame.display.flip() clock.tick(30) pygame.quit() ``` **关键实现说明:** 1. 使用$O(n)$空间复杂度管理粒子状态,每个烟花爆炸时生成50个粒子 2. 粒子运动遵循抛物线轨迹,通过velocity数组实现速度分量控制 3. 颜色采用RGB随机生成,取值范围$(100 \leq r,g,b \leq 255)$保证明亮色调 4. 表白文字通过pygame.font模块渲染,使用黄金色$(255,215,0)$增强视觉效果 5. 烟花重置机制确保动画持续运行,当粒子寿命$age > 50$时自动回收
