用Kotlin破解Android版微信小游戏-跳一跳 _跳一跳

大鹏一日同风起，扶摇直上九万里。这篇文章主要讲述用Kotlin破解Android版微信小游戏-跳一跳相关的知识，希望能为你提供帮助。
前言微信又更新了，从更新日志上来看，似乎只是一次不痛不痒的小更新.
不过，很快就有人发现，原来微信这次搞了个大动作——在小程序里加入了小游戏。今天也是朋友圈被刷爆的缘故。
看到网上有人弄了一个破解版的，于是自己也跟着网上的案例整了一下，感觉挺有意思的。
游戏如下：

用Kotlin破解android版微信小游戏-跳一跳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

主要核心

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() }

在java中是如何操作的？
BackgroundImage4Panel.java

public class BackgroundImage4Panel extends javax.swing.JFrame { /** * serialVersionId */ private static final long serialVersionUID = 1L; private static boolean isFirst = true; private static Point firstPoint; private static Point secondPoint; /** * Creates new form NewJFrame */ public BackgroundImage4Panel() { setSize(675, 1200); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); }/** * 测试入口 * * @param args 参数列表 */ public static void main(String[] args) { AdbCaller.printScreen(); final BackgroundImage4Panel backgroundImage4Panel = new BackgroundImage4Panel(); backgroundImage4Panel.setVisible(true); JPanel jPanel = new JPanel() { /** * serialVersionId */ private static final long serialVersionUID = -1183754274585001429L; protected void paintComponent(Graphics g) { super.paintComponent(g); try { BufferedImage bufferedImage = ImageIO.read(new File(Constants.SCREENSHOT_LOCATION)); BufferedImage newImage = new BufferedImage(675, 1200, bufferedImage.getType()); /** * try to resize */ Graphics gTemp = newImage.getGraphics(); gTemp.drawImage(bufferedImage, 0, 0, 675, 1200, null); gTemp.dispose(); bufferedImage = newImage; g.drawImage(bufferedImage, 0, 0, null); } catch (IOException e) { e.printStackTrace(); } } }; backgroundImage4Panel.getContentPane().add(jPanel); backgroundImage4Panel.getContentPane().getComponent(0).addMouseListener(new MouseListener() { @Override public void mouseClicked(MouseEvent e) { if (isFirst) { System.out.println("first " + e.getX() + " " + e.getY()); firstPoint = e.getPoint(); isFirst = false; } else { secondPoint = e.getPoint(); int distance = distance(firstPoint, secondPoint); System.out.println("distance:" + distance); isFirst = true; AdbCaller.call(distance * 2.19); //magic number try { Thread.sleep(2500); // wait for screencap } catch (InterruptedException e1) { e1.printStackTrace(); } AdbCaller.printScreen(); JPanel jp = ((JPanel) backgroundImage4Panel.getContentPane().getComponent(0)); jp.validate(); jp.repaint(); }}@Override public void mousePressed(MouseEvent e) {}@Override public void mouseReleased(MouseEvent e) {}@Override public void mouseEntered(MouseEvent e) {}@Override public void mouseExited(MouseEvent e) {} }); }/** * 实现图像的等比缩放 * * @param source待处理的图片流 * @param targetW 宽度 * @param targetH 高度 * @return */ public static BufferedImage resize(BufferedImage source, int targetW, int targetH) { int width = source.getWidth(); // 图片宽度 int height = source.getHeight(); // 图片高度 return zoomInImage(source, targetW, targetH); }/** * 对图片进行强制放大或缩小 * * @param originalImage 原始图片 * @return */ public static BufferedImage zoomInImage(BufferedImage originalImage, int width, int height) { BufferedImage newImage = new BufferedImage(width, height, originalImage.getType()); Graphics g = newImage.getGraphics(); g.drawImage(originalImage, 0, 0, width, height, null); g.dispose(); return newImage; }public static int distance(Point a, Point b) {//求两点距离 return (int) Math.sqrt((a.x - b.getX()) * (a.x - b.getX()) + (a.y - b.getY()) * (a.y - b.getY())); } }

AdbCaller.java

public class AdbCaller {public static void call(double timeMilli) { try { Runtime.getRuntime().exec(Constants.ADB_PATH + " shell input touchscreen swipe 170 187 170 187 " + (int) timeMilli); } catch (IOException e) { e.printStackTrace(); } }public static void printScreen() { try { Process p1 = Runtime.getRuntime().exec(Constants.ADB_PATH + " shell screencap -p /sdcard/screenshot.png"); p1.waitFor(); Process p2 = Runtime.getRuntime().exec(Constants.ADB_PATH + " pull /sdcard/screenshot.png " + Constants.SCREENSHOT_LOCATION); p2.waitFor(); } catch (IOException e) { e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } } }

Constants.java

public class Constants { /** * adb所在位置 */ public static final String ADB_PATH = "E:\\android_install_64\\sdk\\platform-tools\\adb.exe"; /** * 截屏文件所在位置 */ public static final String SCREENSHOT_LOCATION = "E:\\android_install_64\\sdk\\platform-tools\\yyh.png"; }

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.java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
