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

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)

            address = address + 0x950;
            //读取 基址2 中存放的值
            address = ReadMemoryValue(address, processName);

            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)
            {

            return n;

今天又增加了无植物无冷却时间的功能

                    // 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);

        }
