在Scala中编写烟花代码可以使用图形库或者游戏开发库来实现，以下是一个简单的烟花代码示例：
import java.awt._ import javax.swing._ object Fireworks extends App { val frame = new JFrame("Fireworks") frame.setSize(800, 600) frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) frame.setVisible(true) val canvas = new Canvas() frame.add(canvas) case class Particle(var x: Int, var y: Int, var dx: Int, var dy: Int, var color: Color) val particles = collection.mutable.ArrayBuffer[Particle]() canvas.createBufferStrategy(3) val bs = canvas.getBufferStrategy while (true) { val g = bs.getDrawGraphics.asInstanceOf[Graphics2D] // Clear canvas g.setColor(Color.BLACK) g.fillRect(0, 0, canvas.getWidth, canvas.getHeight) // Update and draw particles particles.foreach { p => p.x += p.dx p.y += p.dy p.dy += 1 g.setColor(p.color) g.fillOval(p.x, p.y, 5, 5) } // Add new particles if (Math.random() < 0.1) { val color = new Color((Math.random() * 255).toInt, (Math.random() * 255).toInt, (Math.random() * 255).toInt) particles += Particle(canvas.getWidth / 2, canvas.getHeight, (Math.random() * 10 - 5).toInt, (Math.random() * -10 - 10).toInt, color) } bs.show() g.dispose() Thread.sleep(10) } } class Canvas extends JPanel { override def paintComponent(g: Graphics): Unit = { super.paintComponent(g) } } 这个简单的烟花代码会在窗口中显示一些不断上升和爆炸的颗粒。可以根据需求修改代码来实现更加丰富和复杂的烟花效果。
