烟花编程代码可以根据不同的编程语言和平台有不同的实现方式。以下是几种不同编程语言实现烟花效果的方法:
微信小程序烟花编程代码示例
```javascript
// 获取屏幕宽度和高度
const { windowWidth, windowHeight } = wx.getSystemInfoSync();
// 定义烟花粒子类
class Particle {
constructor(x, y, color) {
this.x = x;
this.y = y;
this.color = color;
this.vx = Math.random() * 2 - 1;
this.vy = Math.random() * 2 - 1;
this.alpha = 1;
this.radius = 2;
}
draw(ctx) {
ctx.beginPath();
ctx.arc(this.x, this.y, this.radius, 0, Math.PI * 2);
ctx.fillStyle = `rgba(${this.color}, ${this.alpha})`;
ctx.fill();
}
update() {
this.x += this.vx;
this.alpha -= 0.01;
this.radius -= 0.01;
}
}
// 初始化烟花粒子数组
const particles = [];
for (let i = 0; i < 100; i++) {
particles.push(new Particle(Math.random() * windowWidth, Math.random() * windowHeight, `rgb(${Math.random() * 255}, ${Math.random() * 255}, ${Math.random() * 255})`));
}
// 绘制烟花
function draw() {
ctx.clearRect(0, 0, windowWidth, windowHeight);
particles.forEach(particle => {
particle.draw(ctx);
particle.update();
});
requestAnimationFrame(draw);
}
draw();
```
C语言实现烟花效果
```c
include include include define WND_WIDTH 800 define WND_HEIGHT 600 define NUM 100 struct Particle { int x, y; int color; int vx, vy; int alpha, radius; }; struct Particle particles[NUM]; void init() { srand(time(NULL)); for (int i = 0; i < NUM; i++) { particles[i].x = rand() % WND_WIDTH; particles[i].y = rand() % WND_HEIGHT; particles[i].color = rand() % 256; particles[i].vx = (rand() % 10 - 5) * 2; particles[i].vy = (rand() % 10 - 5) * 2; particles[i].alpha = 255; particles[i].radius = 2; } } void draw() { system("cls"); for (int i = 0; i < NUM; i++) { particles[i].draw(); particles[i].update(); } } int main() { init(); while (1) { draw(); Sleep(10); } return 0; } ``` Python使用matplotlib实现烟花效果
