以 78.屏蔽跌落数据实现摔不死和模拟原地摔死 它的代码为基础进行修改

上一个内容里模拟坠落数据包，不成功，是因为内存没有对齐

op是数据类型（比如2表示int类型数字，1表示char一个字节），然后需要的数据是op+数据也就是 02 1，这个1是一个数字是一个int类型的数字在内存中是01 00 00 00 这样的所以完整的数据是 02 01 00 00 00 这样，然后由于char un[2]{};写到了void* oldPointer前面，导致char index = 0;char op = 0;不对齐8字节，也就把数据变成了 index 02 00 00 00 00 00 00 10 00 00 00 这样的数据，我们要的是index 02 01 00 00 00这样的

class EnCode// 用于表示数据解析约定的数据
{
private:public:void* oldPointer = 0;// 当前数据包里数据的内存地址（游戏里的地址）char un[2]{};// char index = 0;// op + un[3]是四字节，op与buffer是6字节，如果自动内存对齐op与buffer可能不会挨在一起char op = 0;/*这个位置会导致编译器代码生成出现问题就是在当前文件一个类里写一个新的函数声明这个时候会因为下方的 union 导致编译器无法通过函数声明在cpp实现函数，这是因为编译器不知道下方的 union 是什么东西导致的*/union{char dataPool[0x8];//char dataPool[0x4];int lenth;char byte;short stval;int val;float fval;/*	int dbval;int lval = 0;*/double dbval;long long lval = 0;};char* pointer = 0;// 为了方便操作会把数据包的数据复制到我们自己的内存空间里，这个变量就是用来指向我们自己的内存空间的int AllocCount = 0;// 记录内存大小
protected:void AllocPointer(int size);
public:EnCode();EnCode(char*& buff, char ExIndex = 1);EnCode& operator=(char*& buff);void Init(char*& buff, char EnIndex = 1);~EnCode();
};

内存对齐，比如一个结构里最大的数据类型是8字节，那么所有的数据不满8字节的都会向8字节对齐，如果触发自动对齐它会在数据后面补0，正常开发是没问题的，但是我们是要模拟数据包，所以不能让结构触发自动对齐

第一个例子

2字节 1

4字节 2

2字节 3

8字节 4

上方就会触发自动对齐，自动向最大的数据类型对齐，也就是向8字节对齐它会把数据搞成 01 01 00 00 00 00 00 00 02 02 02 02 00 00 00 00 03 03 00 00 00 00 00 00 04 04 04 04 04 04 04 04这样可以看到1、2、3后面都有0，这个0就是触发自动对齐补的字节

第二个例子

4字节 2

2字节 1

2字节 3

8字节 4

上方的写法就不会触发内存对齐，它的内存 02 02 02 02 01 01 03 03 04 04 04 04 04 04 04 04

触发自动内存对齐的条件，结构体中第一个变量是1字节第二个变量是2字节，第一个变量会触发自动内存对齐，第一个变量会向2字节对齐，第一个变量是1字节第二个变量是4字节，第一个变量会触发自动内存对齐，第一个变量会向4字节对齐，第一个变量是2字节第二个变量是4字节，第一个变量会触发自动内存对齐，第一个变量会向4字节对齐，第一个变量是2字节第二个变量也是2字节第三个变量是4字节，这样不会触发自动内存对齐，第一个变量是2字节第二个变量也是2字节第三个变量是8字节，这时内存中的样子是第一个变量和第二个变量的数据紧挨着，然后在第二个变量后面补4个0，让第一个变量和第二个变量的大小加起来变成8字节

上一个内容实现了屏蔽坠落伤血，然后对发送的跳跃相关移动相关的数据包进行拦截实现了高速移动、高速跳跃，本次是模拟移动数据包实现人物走路

通过之前的分析，游戏中的走路是先发送了15 1的数据包，走路完成时发送了 15 0的数据包，本次就是模拟发送这俩数据包

效果图：
