植物大战僵尸——纯C实现无限阳光

大致思路：

1.获取游戏窗口，使用FindWindow函数

2.获取游戏PID（ProcessID）,使用GetWindowThreadProcessId函数

3.获取游戏进程句柄，使用OpenProcess函数

4.读取游戏阳光基址 5.读取后修改阳光数值

大家查看源码后可能疑惑的问题：

1.上图源码中的窗口信息是怎么找到的？解析如下↓↓

打开VS中的Spy++,将准星拖入植物大战僵尸窗口上，方可一键获取窗口信息，操作如下↓↓

2.源码中阳光的基址和偏移是怎么找到的？

这涉及游戏逆向相关的基础：需看得懂汇编和熟练运用调试器，如CE(CheatEngine)

以后会增加更多有趣功能，麻烦点点关注

源码如下：

本人癖好源码内不喜欢出现中文（包括注释）如果有地方看不懂可以用翻译软件

#define _CRT_SECURE_NO_WARNINGS 1
#include <stdio.h>
#include <Windows.h>
int main()
{
    //My thinking:
    //1.Get game window
    //2.Get game process id
    //3.Get process handle
    //4.Get sunshine address
    //5.Modify sunshine data

    }

    DWORD GamePid;

        WriteProcessMemory(Hprocess, (void*)(SunshineFirstOffsetValue + SunshineSecondOffset), &ModifySunshineValue, 4, &Size);
    }
