成果1077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 [duration(ms)] (Default: touchscreen) # 模拟长按$ adb shell screencap # 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 / kL = p2 - p1获取到起始点和结束点的坐标源码开发环境： Kotlin, IetelliJ IDEAhttps://github.com/iOSDevLog/JumpJump主要源码fun main(args: Array) { 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...
