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()
}

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
