表白烟花代码

天天敲代码的朋友，有没有想过代码也可以变得很酷炫又浪漫？今天就教大家用Python模拟出绽放的烟花，工作之余也可以随时让程序为自己放一场烟花秀。

python炫酷烟花表白源代码

这个有趣的小项目并不复杂，只需一点可视化技巧，100余行Python代码和程序库Tkinter，最后我们就能达到下面这个效果：

学完本教程后，你也能做出这样的烟花秀。

整体概念梳理

我们的整个理念比较简单。

我们这里通过让画面上一个粒子分裂为X数量的粒子来模拟爆炸效果。粒子会发生"膨胀”，意思是它们会以恒速移动且相互之间的角度相等。这样就能让我们以一个向外膨胀的圆圈形式模拟出烟花绽放的画面。经过一定时间后，粒子会进入"自由落体”阶段，也就是由于重力因素它们开始坠落到地面，仿若绽放后熄灭的烟花。

while (y_move y_click)//如果点击的位置小于最大高度。

{

g = (((int) Math.round(Math.random() * 4321)) % 200) + 55;

b = (((int) Math.round(Math.random() * 4321)) % 200) + 55;//rgb是光的三原色，这个就是烟花产生的颜色，这里定义成随机的，但在一个范围里

g1.setColor(new Color(r, g, b));//把画笔改成那个颜色

g1.fillOval(x_click, y_move, 5, 5);//画一个这样的圆

for (int j = 0; j = 10; j++) {

if (r 55)

if (b 55)

b -= 20;

}

g1.setColor(Color.black);

g1.fillOval(x_click, y_move + 5 * 10, 5, 5);//把上一次画的彩色圆，用黑色画一遍，就能让它消失在背景里

} catch (InterruptedException e) {

}

}//上面这段代码是烟花的升上去的那一串东西的效果

g1.setColor(Color.black);

g1.fillOval(x_click, y_move + (j * 5), 5, 5);

try {

Thread.currentThread().sleep((v++) / 3);

for (int i = 0; i = 25; i++) {

if (i 23) {

g1.drawOval(x_click - 3 * (i + 1), y_click - 3 * (i + 1),

6 * (i + 1), 6 * (i + 1));

g1.drawOval(x_click - 3 * (i + 2), y_click - 3 * (i + 2),

6 * (i + 2), 6 * (i + 2));

}//上面这段是画爆炸的效果

try {

Thread.currentThread().sleep(v++);//停一下，看效果

} catch (InterruptedException e) {

}

g1.setColor(Color.black);

g1.drawOval(x_click - 3 * i, y_click - 3 * i, 6 * i, 6 * i);//然后画黑圈，相当于让彩圈消失。

}

public void mousePressed(MouseEvent e) {//点击从这里开始~~~~~~~~~~~~~~

x = e.getX();

y = e.getY();//得到鼠标点击的坐标

Thread one = new Thread(this);//新建一个线程

one.start();//启动这个线程，到上面的run方法

one = null;//把这个线程置为空，让它执行完以后就释放

}

如果你想一下自己写要怎样写这个程序，就很容易理解这个程序了。

一直从下向上画圆，然后把下面的圆擦掉，就能得到一个向上升的烟花效果，

爆炸效果就是先画小圆再画大圆，然后擦掉小圆，再擦掉大圆。

这个是烟花代码！怎么改好看点？

在编写那个烟花的程序（java），以下是对烟花进行绘制的代码，我是新手看不懂，请帮忙解释下呢··

就是找了三个随机数, r,g,b作为颜色的初始色彩,在三个数字上偏移, 得到相近的颜色.. 并画出来..
