跳一跳

微信小程序可以玩游戏了，我们来破解一下《跳一跳》这个官方出品的小游戏吧。

思路

用usb调试安卓手机，用adb截图并用鼠标测量距离，然后计算按压时间后模拟按压。

$ adb shell input swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen) # 模拟长按
$ adb shell screencap <filename> # 保存截屏到手机
$ adb pull /sdcard/screen.png # 下载截屏文件到本地
得到手指按的时间 t
时间 = 距离 / 速度(常量) t = L / k
L = p2 - p1
获取到起始点和结束点的坐标
源码

开发环境： Kotlin, IetelliJ IDEA

https://github.com/iOSDevLog/JumpJump

主要源码
fun main(args: Array<String>) {
val jumpjump = JumpJump()
var isFirst = true
var firstPoint: Point? = null
var secondPoint: Point?

val jPanel = object : JPanel() {
override fun paintComponent(g: Graphics) {
super.paintComponent(g)
try {
var bufferedImage = ImageIO.read(File(SCREENSHOT_LOCATION))
val newImage = BufferedImage(675, 1200, bufferedImage.getType())
val gTemp = newImage.graphics
gTemp.drawImage(bufferedImage, 0, 0, 675, 1200, null)
gTemp.dispose()
bufferedImage = newImage
g.drawImage(bufferedImage, 0, 0, null)
} catch (e: IOException) {
e.printStackTrace()
}
}
}

jPanel.addMouseListener(object : MouseListener {
override fun mouseReleased(e: MouseEvent?) {
}

override fun mouseEntered(e: MouseEvent?) {
}

override fun mouseClicked(e: MouseEvent?) {
}

override fun mouseExited(e: MouseEvent?) {
}

override fun mousePressed(e: MouseEvent?) {
println("mousePressed")
e.let {
if (isFirst) {
println("first {pomt" + e!!.x + " " + e.y)
firstPoint = e.point
isFirst = false
} else {
secondPoint = e!!.point
val distance = distance(firstPoint!!, secondPoint!!)
println("distance:" + distance)
isFirst = true
//magic number
call(distance * 2.2)
try {
// wait for screen cap
Thread.sleep(2500)
} catch (e1: InterruptedException) {
e1.printStackTrace()
}

printScreen()

jPanel.validate()
jPanel.repaint()
}
}
}

})

jumpjump.isVisible = true
jumpjump.contentPane.add(jPanel)

printScreen()
jumpjump.repaint()
jumpjump.validate()
}

fun distance(a: Point, b: Point): Int {
return Math.sqrt((a.x - b.getX()) * (a.x - b.getX()) + (a.y - b.getY()) * (a.y - b.getY())).toInt()
}
使用方法

在电脑上下载好adb
打开安卓手机的usb调试模式并授权连接的电脑
打开微信跳一跳，并点击开始
在Constans.kt中配置好adb路径与截图路径，运行
在弹出的窗口中先点击小人底部适当位置，然后再点想要跳的箱子的位置即可完成
