C# 操作地址 从内存中读取写入数据(初级)
本示例以植物大战僵尸为例, 实现功能为 每1秒让阳光刷新为 9999.本示例使用的游戏版本为 [植物大战僵尸2010年度版], 使用的辅助查看内存地址的工具是 CE.
由于每次启动游戏, 游戏中阳光地址都是变的, 唯一不变的基址1, 我们要通过CE工具找到基址1的地址, 可以算出阳光的地址.
基址2的地址 = 基址1中的值 + 偏移1;
阳光的的地址 = 基址2中的值 + 偏移2;
以下为简单示例: 窗口界面一个按钮 和 一个定时器
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Runtime.InteropServices; using System.Diagnostics; namespace ZhiWuDaZhanJiangShi { public partial class Form1 : Form { public Form1() { InitializeComponent(); } #region API //从指定内存中读取字节集数据 [DllImportAttribute("kernel32.dll", EntryPoint = "ReadProcessMemory")] public static extern bool ReadProcessMemory(IntPtr hProcess,IntPtr lpBaseAddress,IntPtr lpBuffer,int nSize,IntPtr lpNumberOfBytesRead); //从指定内存中写入字节集数据 [DllImportAttribute("kernel32.dll", EntryPoint = "WriteProcessMemory")] public static extern bool WriteProcessMemory(IntPtr hProcess,IntPtr lpBaseAddress,int[] lpBuffer,int nSize, IntPtr lpNumberOfBytesWritten ); //打开一个已存在的进程对象，并返回进程的句柄 [DllImportAttribute("kernel32.dll", EntryPoint = "OpenProcess")] public static extern IntPtr OpenProcess(int dwDesiredAccess, bool bInheritHandle, int dwProcessId); //关闭一个内核对象。其中包括文件、文件映射、进程、线程、安全和同步对象等。 [DllImport("kernel32.dll")] private static extern void CloseHandle(IntPtr hObject); #endregion #region 使用方法 //根据进程名获取PID public static int GetPidByProcessName(string processName) { Process[] arrayProcess = Process.GetProcessesByName(processName); foreach (Process p in arrayProcess) { return p.Id; } return 0; } //读取内存中的值 public static int ReadMemoryValue(int baseAddress, string processName) { try { byte[] buffer = new byte[4]; //获取缓冲区地址 IntPtr byteAddress = Marshal.UnsafeAddrOfPinnedArrayElement(buffer, 0); //打开一个已存在的进程对象 0x1F0FFF 最高权限 IntPtr hProcess = OpenProcess(0x1F0FFF, false, GetPidByProcessName(processName)); //将制定内存中的值读入缓冲区 ReadProcessMemory(hProcess, (IntPtr)baseAddress, byteAddress, 4, IntPtr.Zero); //关闭操作 CloseHandle(hProcess); //从非托管内存中读取一个 32 位带符号整数。 return Marshal.ReadInt32(byteAddress); } catch { return 0; } } //将值写入指定内存地址中 public static void WriteMemoryValue(int baseAddress, string processName, int value) { try { //打开一个已存在的进程对象 0x1F0FFF 最高权限 IntPtr hProcess = OpenProcess(0x1F0FFF, false, GetPidByProcessName(processName)); //从指定内存中写入字节集数据 WriteProcessMemory(hProcess, (IntPtr)baseAddress, new int[] { value }, 4, IntPtr.Zero); //关闭操作 CloseHandle(hProcess); } catch { } } #endregion //游戏内存基址 private int baseAddress = 0x0015E944; //游戏进程名字 private string processName = "PlantsVsZombies"; //开启/关闭 功能 的按钮 private void button1_Click(object sender, EventArgs e) { if (GetPidByProcessName(processName) == 0) { MessageBox.Show("游戏没有运行!"); return; } if (button1.Text == "开启") { button1.Text = "关闭"; timer1.Enabled = true; } else { button1.Text = "开启"; timer1.Enabled = false; } } //定时器 private void timer1_Tick(object sender, EventArgs e) { if (GetPidByProcessName(processName) == 0) { timer1.Enabled = false; } //baseAddress : 游戏内存基址 processName : 游戏进程名 //读取 基址1 中存放的值 int address = ReadMemoryValue(baseAddress, processName); //计算 基址2的地址 = 基址1中的值 + 偏移量1 address = address + 0x868; //读取 基址2 中存放的值 address = ReadMemoryValue(address, processName); //计算 阳光的地址 = 基址2中的值 + 偏移量2 address = address + 0x5578; //给阳光地址中写入数值,0x378 : 888 WriteMemoryValue(address, processName, 0x378); } } }
下面增加了一个刷新金币的示例 (注意, 金币值是界面的金币输 除以 10 , 我们刷100 在界面里面显示为1000)
private void button2_Click(object sender, EventArgs e) { if (GetPidByProcessName(processName) == 0) { MessageBox.Show("游戏没有运行!"); return; } //baseAddress : 游戏内存基址 processName : 游戏进程名 //读取 基址1 中存放的值 int address = ReadMemoryValue(baseAddress, processName); //计算 基址2的地址 = 基址1中的值 + 偏移量1 address = address + 0x950; //读取 基址2 中存放的值 address = ReadMemoryValue(address, processName); //计算 阳光的地址 = 基址2中的值 + 偏移量2 address = address + 0x50; //给阳光地址中写入数值,0x378 : 888 WriteMemoryValue(address, processName, GetInt(textBox2.Text)); } private int GetInt(string s) { int n = 0; int.TryParse(s, out n); if (n <= 0) { n = 100; } return n; }
今天又增加了无植物无冷却时间的功能
int count = 0; private void Form1_Load(object sender, EventArgs e) { if (GetPidByProcessName(processName) != 0) { int address = ReadMemoryValue(baseAddress, processName); address = address + 0x868; address = ReadMemoryValue(address, processName); address = address + 0x15c; address = ReadMemoryValue(address, processName); address = address + 0x24; address = ReadMemoryValue(address, processName); count = address; label3.Text = "植物栏个数: " + address.ToString() + " 个"; } } private void timer2_Tick(object sender, EventArgs e) { if (GetPidByProcessName(processName) == 0) { timer2.Enabled = false; } if (count > 0) { for (int i = 0; i < count; i++) { int address = ReadMemoryValue(baseAddress, processName); address = address + 0x868;//一级地址 address = ReadMemoryValue(address, processName); address = address + 0x15c;//二级地址 address = ReadMemoryValue(address, processName); address = address + 0x4c;//第一栏 植物的地址 // 每后一个植物 地址 偏移 50 (在十进制里是80) //偏移 0x24 的地址 是标示是否在冷却中 值 :( 0 : 为冷却中, 1 为冷却完成) address = address + 80 * i + 0x24; WriteMemoryValue(address, processName, 1); //如果不偏移 0x24 的地址为冷却时间地址, 值不确定, 一般最大设为6000 也可以完成此功能 //address = address + 80 * i; //WriteMemoryValue(address, processName, 6000); } } else { int address = ReadMemoryValue(baseAddress, processName); address = address + 0x868; address = ReadMemoryValue(address, processName); address = address + 0x15c; address = ReadMemoryValue(address, processName); address = address + 0x24; address = ReadMemoryValue(address, processName); count = address; label3.Text = "植物栏个数: " + address.ToString() + " 个"; } } private void button3_Click(object sender, EventArgs e) { if (GetPidByProcessName(processName) == 0) { MessageBox.Show("游戏没有运行!"); return; } if (button3.Text == "有冷却") { button3.Text = "无冷却"; timer2.Enabled = true; } else { button3.Text = "有冷却"; timer2.Enabled = false; } }
