前言
微信又更新了，從更新日誌上來看，似乎只是一次不痛不癢的小更新. 不過，很快就有人發現，原來微信這次搞了個大動作——在小程式里加入了小遊戲。今天也是朋友圈被刷爆的緣故。
看到網上 有人弄了一個破解版的，於是自己也跟著網上的案例整了一下，感覺挺有意思的。
遊戲如下：
勞動成果
跳一跳
微信小程式可以玩遊戲了，我們來破解一下《跳一跳》這個官方出品的小遊戲吧。
思路
用usb除錯安卓手機，用adb截圖並用滑鼠測量距離，然後計算按壓時間後模擬按壓。
$ adb shell input swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen) # 模擬長按
$ adb shell screencap <filename> # 儲存截圖到手機
$ adb pull /sdcard/screen.png # 下載截圖檔案到本地
複製程式碼主要核心
- 得到手指按的時間 t
- 時間 = 距離 / 速度(常量) t = L / k
- L = p2 - p1
- 獲取到起始點和結束點的座標

複製程式碼使用方法
- 在電腦上下載好adb
- 開啟安卓手機的usb除錯模式並授權連線的電腦
- 開啟微信跳一跳，並點選開始
- 在Constans.java中配置好adb路徑與截圖路徑，執行
- 在彈出的視窗中先點選小人底部適當位置，然後再點想要跳的箱子的位置即可完成
