还记得前段时间很火的小程序“跳一跳”吗？程序员带你花式操作！

有体会过连一只猫都玩不过的感jio吗？

在好友圈里垫底，有点扎心，是时候发挥一下程序员的力量了。

想学习的朋友可以来c/c++学习交流裙：【六六六，二九五，四九八】邀请码【云志】，群里有全套的c/c++资料，任你挑选！

先做一波测试，分别测试t1~tn的值时，能跳远距离，构造出时间与距离的方程。

来一组adb shell input swipe 1 1 1 1 tn，时间与距离呈线性变化，简单的取个比例，也可用回归方程计算出比较精确的比例系数。

得出了一个方程 t = 189 * s/ 0.8

接下来要测量s的值，那么s的值怎么来，采取屏幕采点的方式进行策略距离。

根据我们初中学的勾股定理很容易计算出s = k * [(x1-x2)^2 + (y1-y2)^2]

^

1/2，其中k是比例系数，那么坐标（x1，y1）和（x2，y2）怎么获得。很简单，鼠标左键点一下获得点（x1，y1），右键点一下获得（x2，y2）并开始运行。

实际代码如何实现如下。

预备工具：adb.exe，AdbWinApi.dll，AdbWinUsbApi.dll

打开VS创建win32程序。

新建头文件Jump.h

char const *const EXEC_HEAD = "adb shell input swipe 1 1 1 1 ";

char const *const SCREENCAP = "adb shell screencap -p /sdcard/jump_display.png";

char const *const PULL = "adb pull /sdcard/jump_display.png";

char const *const TAP = "adb shell input tap ";

class Jump

{

private:

int duration;

float distance;

int width;

int height;

public:

Jump();

~Jump();

void initPhysicalSize();

void exec();

void calculateDistance(float d);

void calculateDuration();

void screencap();

void loadimage();

int getWidth();

int getHeight();

void clickScreen(int w, int h);

}

新建C++文件Jump.cpp

#define _CRT_SECURE_NO_WARNINGS

#include "Jump.h"

using namespace std;

ifstream iss("size.txt");

char size[10];

if(!iss.is_open()) return;

iss.seekg(15);

if(!iss.eof())

{

iss.get(size,10);

}

iss.close();

const char * split = "x";

char *p;

p = strtok(size,split);

int w_len = strlen(p);

width = 0;

for(int index = 0; index

{

width = width + pow(10,w_len - index - 1) * (int)(p[index]-48);

}

p = strtok(NULL,split);

int h_len = strlen(p);

height = 0;

for(int index = 0; index

{

height = height + pow(10,h_len-index - 1) * (int)(p[index]-48);

}

}

void Jump::calculateDistance(float d)

{

distance = d;

}

void Jump::calculateDuration()

{

duration = (int)(189 * 1.0 * distance / 0.8);

}

void Jump::exec()

{

ostringstream oss;

oss

system(oss.str().c_str());

}

void Jump::screencap()

{

system(SCREENCAP);

}

void Jump::loadimage()

{

操作方式，打开跳一跳游戏--->点击开始游戏--->打开程序--->左键选择起点坐标--->右键选择终点坐标并运行，loop。

代码写的很随意，可能比例系数会不一样。
