python 实现漂亮的烟花,樱花,玫瑰花

时间:2024-04-16 10:35:12

显着无聊收集了下用python绘制烟花,绘制樱花,烟花+樱花,飘零雪花,玫瑰花的python绘制代码,可以来练手什么的哦。

同时python实现八音符,坦克大战,贪吃蛇,FlappyBird等都可以参考哦=> code

一、python实现烟花

效果图:

代码如下 :

import tkinter as tk
from PIL import Image, ImageTk
from time import time, sleep
from random import choice, uniform, randint
from math import sin, cos, radians

# 模拟重力
GRAVITY = 0.05
# 颜色选项(随机或者按顺序)
colors = [\'red\', \'blue\', \'yellow\', \'white\', \'green\', \'orange\', \'purple\', \'seagreen\', \'indigo\', \'cornflowerblue\']

particles 类

粒子在空中随机生成随机,变成一个圈、下坠、消失

属性:
    - id: 粒子的id
    - x, y: 粒子的坐标
    - vx, vy: 在坐标的变化速度
    - total: 总数
    - age: 粒子存在的时长
    - color: 颜色
    - cv: 画布
    - lifespan: 最高存在时长

\'\'\'


class Particle:

    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

        # 粒子范围扩大
        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)

        # 以*落体坠落
        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

        # 移除超过最高时长的粒子
        elif self.cid is not None:
            cv.delete(self.cid)
            self.cid = None

    # 扩大的时间
    def expand (self):
        return self.age <= 1.2

    # 粒子是否在最高存在时长内
    def alive(self):
        return self.age <= self.lifespan

循环调用保持不停
\'\'\'
def simulate(cv):
    t = time()
    explode_points = []
    wait_time = randint(10, 100)
    numb_explode = randint(6, 10)
    # 创建一个所有粒子同时扩大的二维列表
    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 = Particle(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
    # 1.8s内一直扩大
    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
    # 循环调用
    root.after(wait_time, simulate, cv)


def close(*ignore):
    """退出程序、关闭窗口"""
    global root
    root.quit()


if __name__ == \'__main__\':
    root = tk.Tk()
    cv = tk.Canvas(root, height=400, width=600)
    # 选一个好看的背景会让效果更惊艳!
    image = Image.open("./image.jpg")//这里自己选择好背景图片哦
    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()

二、动态樱花

效果如下:

代码如下:

import turtle as T
import random
import time

# 画樱花的躯干(60,t)
def Tree(branch, t):
    time.sleep(0.0005)
    if branch > 3:
        if 8 <= branch <= 12:
            if random.randint(0, 2) == 0:
                t.color(\'snow\')  # 白
            else:
                t.color(\'lightcoral\')  # 淡珊瑚色
            t.pensize(branch / 3)
        elif branch < 8:
            if random.randint(0, 1) == 0:
                t.color(\'snow\')
            else:
                t.color(\'lightcoral\')  # 淡珊瑚色
            t.pensize(branch / 2)
        else:
            t.color(\'sienna\')  # 赭(zhě)色
            t.pensize(branch / 10)  # 6
        t.forward(branch)
        a = 1.5 * random.random()
        t.right(20 * a)
        b = 1.5 * random.random()
        Tree(branch - 10 * b, t)
        t.left(40 * a)
        Tree(branch - 10 * b, t)
        t.right(20 * a)
        t.up()
        t.backward(branch)
        t.down()

# 掉落的花瓣
def Petal(m, t):
    for i in range(m):
        a = 200 - 400 * random.random()
        b = 10 - 20 * random.random()
        t.up()
        t.forward(b)
        t.left(90)
        t.forward(a)
        t.down()
        t.color(\'lightcoral\')  # 淡珊瑚色
        t.circle(1)
        t.up()
        t.backward(a)
        t.right(90)
        t.backward(b)

# 绘图区域
t = T.Turtle()
# 画布大小
w = T.Screen()
t.hideturtle()  # 隐藏画笔
t.getscreen().tracer(5, 0)
w.screensize(bg=\'wheat\')  # wheat小麦
t.left(90)
t.up()
t.backward(150)
t.down()
t.color(\'sienna\')

# 画樱花的躯干
Tree(60, t)
# 掉落的花瓣
Petal(100, t)
w.exitonclick()

            if random.randint(0, 2) == 0:
                t.color(\'snow\')  # 白
            else:
                t.color(\'lightcoral\')  # 淡珊瑚色
            t.pensize(branch / 3)
        elif branch < 8:
