用Go语言实现烟花的代码

好的，以下是用Go语言实现火花效果的示例代码：

package main

import (
	"fmt"
	"math/rand"
	"time"
)

const (
	width  = 80
	height = 15
)

type spark struct {
	x, y   int
	vx, vy float64
}

func main() {
	rand.Seed(time.Now().UnixNano())
	grid := make([][]bool, height)
	for i := range grid {
		grid[i] = make([]bool, width)
	}
	var sparks []*spark
	for {
		// Create new sparks at random locations
		if rand.Float64() < 0.5 {
			sparks = append(sparks, &spark{
				x: 0,
				y: rand.Intn(height),
				vx: rand.Float64()*3 + 1,
				vy: (rand.Float64() - 0.5) / 2,
			})
		}
		// Update the sparks
		for _, s := range sparks {
			s.x += int(s.vx)
			s.y += int(s.vy * s.vx)
			if s.x < 0 || s.x >= width || s.y < 0 || s.y >= height {
				continue
			}
			grid[s.y][s.x] = true
			s.vx *= 0.9
			s.vy *= 0.9
		}
		// Render the grid
		for y := range grid {
			for x := range grid[y] {
				if grid[y][x] {
					fmt.Print("*")
				} else {
					fmt.Print(" ")
				}
			}
			fmt.Println()
		}
		// Clear the grid
		for i := range grid {
			for j := range grid[i] {
				grid[i][j] = false
			}
		}
		// Remove dead sparks
		newSparks := sparks[:0]
		for _, s := range sparks {
			if s.vx > 0.1 {
				newSparks = append(newSparks, s)
			}
		}
		sparks = newSparks
		// Sleep for a short time
		time.Sleep(50 * time.Millisecond)
	}
}

这段代码实现了一个火花效果，随机生成火花并模拟它们的飞行轨迹，最后在终端上展示出来。
