用python绘制动态烟花
时间: 2023-02-20 22:07:07 浏览: 50
你可以使用Python的matplotlib库来绘制动态烟花,可以参考下面的示例代码:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
fig, ax = plt.subplots()
xdata, ydata = [], []
ln, = plt.plot([], [], 'ro', animated=True)
def init():
ax.set_xlim(0, 2*np.pi)
ax.set_ylim(-1, 1)
return ln,
def update(frame):
xdata.append(frame)
ydata.append(np.sin(frame))
ln.set_data(xdata, ydata)
return ln,
ani = FuncAnimation(fig, update, frames=np.linspace(0, 2*np.pi, 128),
init_func=init, blit=True)
plt.show()

用python绘制出烟花
抱歉,作为语言模型AI,我无法绘制出烟花。但是,我可以提供一份Python代码,可以在Python中实现一个烟花效果。你可以尝试运行以下代码:
```python
import pygame
import random
# 初始化pygame
pygame.init()
# 定义窗口大小
width, height = 800, 600
# 创建窗口
screen = pygame.display.set_mode((width, height))
# 设置窗口标题
pygame.display.set_caption("Fireworks")
# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
# 定义烟花粒子类
class Particle:
def __init__(self, x, y, size):
self.x = x
self.y = y
self.size = size
self.colour = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
def display(self):
pygame.draw.circle(screen, self.colour, (self.x, self.y), self.size)
def move(self):
self.x += random.randint(-5, 5)
self.y += random.randint(-5, 5)
self.size -= 0.1
# 定义烟花类
class Firework:
def __init__(self):
self.particles = []
self.exploded = False
self.colour = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
for i in range(100):
self.particles.append(Particle(random.randint(0, width), height, random.randint(2, 5)))
def display(self):
if not self.exploded:
pygame.draw.circle(screen, self.colour, (self.particles[0].x, self.particles[0].y), 5)
for particle in self.particles:
particle.display()
def explode(self):
self.exploded = True
for particle in self.particles:
particle.colour = self.colour
speed = random.randint(1, 10)
angle = random.uniform(0, 2 * 3.14)
particle.xspeed = speed * math.cos(angle)
particle.yspeed = speed * math.sin(angle)
def move(self):
if not self.exploded:
self.particles[0].y -= 10
if self.particles[0].y <= 0:
self.explode()
else:
for particle in self.particles:
particle.move()
# 创建烟花列表
fireworks = []
# 游戏主循环
while True:
# 处理事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
# 添加新烟花
if random.randint(1, 10) == 1:
fireworks.append(Firework())
# 绘制背景
screen.fill(BLACK)
# 显示和移动烟花
for firework in fireworks:
firework.display()
firework.move()
# 删除烟花
fireworks = [firework for firework in fireworks if not firework.exploded]
# 更新屏幕
pygame.display.update()
```
这是一份简单的代码,可能不是很完美,但它可以帮助你开始制作自己的烟花效果。
python画静态烟花_python代码绘制动态烟花(代码简单只需二十几行)
以下是Python代码绘制静态烟花:
```python
import turtle
import random
colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple']
turtle.speed(0)
turtle.hideturtle()
for i in range(50):
x = random.randint(-400, 400)
y = random.randint(-400, 400)
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
color = random.choice(colors)
turtle.color(color)
size = random.randint(10, 40)
turtle.dot(size)
turtle.done()
```
以下是Python代码绘制动态烟花:
```python
import turtle
import random
colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple']
turtle.speed(0)
turtle.hideturtle()
for i in range(50):
x = random.randint(-400, 400)
y = random.randint(-400, 400)
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
color = random.choice(colors)
turtle.color(color)
size = random.randint(10, 40)
for i in range(10):
turtle.dot(size)
turtle.penup()
turtle.forward(size * 2)
turtle.pendown()
turtle.done()
```
以上代码中,我们使用turtle库来绘制烟花。在静态烟花中,我们随机生成50个位置,并使用dot方法来绘制烟花。在动态烟花中,我们在静态烟花的基础上,加入了循环,让烟花变得动态起来。
