烟花灯电脑编程可以通过多种方式实现,以下是使用Python和Pygame库创建烟花效果的基本步骤和示例代码:
准备工作
安装Pygame库
```bash
pip install pygame
```
代码实现
```python
import pygame
import random
import math
初始化Pygame
pygame.init()
屏幕设置
WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("电子烟花模拟器")
颜色定义
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
COLORS = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0),
(255, 0, 255), (0, 255, 255), (255, 165, 0)]
class Particle:
def __init__(self, x, y, color):
self.x = x
self.y = y
self.color = color
self.speed = random.uniform(2, 6)
self.angle = random.uniform(0, math.pi * 2)
self.life = 100
def update(self):
self.x += self.speed * math.cos(self.angle)
self.y += self.speed * math.sin(self.angle)
self.life -= 1
def draw(self, surface):
pygame.draw.circle(surface, self.color, (int(self.x), int(self.y)), 5)
def random_bright_color():
return (random.randint(100, 255), random.randint(100, 255), random.randint(100, 255))
创建烟花实例
firework = Firework()
主循环
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
screen.fill(BLACK)
for particle in firework.particles:
particle.update()
particle.draw(screen)
if firework.particles:
firework.particles.pop(0)
pygame.display.flip()
pygame.quit()
```
代码解释
初始化Pygame
```python
pygame.init()
```
屏幕设置
```python
WIDTH, HEIGHT = 800, 600
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("电子烟花模拟器")
```
颜色定义
```python
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
COLORS = [(255, 0, 0), (0, 255, 0), (0, 0, 255), (255, 255, 0),
(255, 0, 255), (0, 255, 255), (255, 165, 0)]
```
