Python结合turtle简单开发一个烟花小工具

python yanhua.py

import turtle
import random
import math

# 设置屏幕
screen = turtle.Screen()
screen.bgcolor("black")
screen.title("Python 烟花效果")
screen.tracer(0, 0)  # 关闭自动刷新，提高性能

# 烟花粒子类
class FireworkParticle:
    def __init__(self, x, y, color):
        self.t = turtle.Turtle()
        self.t.shape("circle")
        self.t.shapesize(0.1, 0.1)  # 小圆点
        self.t.color(color)
        self.t.penup()
        self.t.goto(x, y)
        self.t.pendown()
        
        # 随机方向和速度
        angle = random.uniform(0, 2 * math.pi)
        speed = random.uniform(2, 6)
        self.vx = math.cos(angle) * speed
        self.vy = math.sin(angle) * speed
        self.life = random.randint(20, 40)  # 存活帧数

    def move(self):
        self.t.setx(self.t.xcor() + self.vx)
        self.t.sety(self.t.ycor() + self.vy)
        self.vy -= 0.1  # 重力
        self.life -= 1
        return self.life > 0

    def hide(self):
        self.t.hideturtle()

# 存储所有粒子
particles = []

# 创建烟花函数
def create_firework(x, y):
    colors = ["red", "orange", "yellow", "green", "blue", "purple", "white", "pink"]
    for _ in range(30):  # 每个烟花30个粒子
        color = random.choice(colors)
        particles.append(FireworkParticle(x, y, color))

# 随机在屏幕中发射烟花
def launch_random_firework():
    x = random.randint(-300, 300)
    y = random.randint(-100, 200)
    create_firework(x, y)

# 主循环
frame = 0
while True:
    frame += 1
    if frame % 60 == 0:  # 每60帧（约1秒）发射一个烟花
        launch_random_firework()

    # 更新粒子
    for p in particles[:]:
        if not p.move():
            p.hide()
            particles.remove(p)

    screen.update()  # 手动刷新画面
    turtle.delay(10)  # 控制速度

# 注意：正常退出会被无限循环阻塞，可按 Ctrl+C 强制退出
