scala编写烟花代码怎么写

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。
