二级偏移的查找是个难点，对《植物大战僵尸》年度版二级偏移的查找，是个不错的思路，或许能广泛应用的其他游戏上。
几个要点，总结一下：
1、根据阳光数找到的第一个地址：1CDEB6F8，绝大多数人都不会有什么问题。操作要点是：接着要对其进行“找出是什么访问了这个地址”的操作。
2、然后会看到红色的[edx+00005578]的提示，和“要查找的地址指针的值可能是 1CDE6180”，这里也没什么问题。
3、需要对地址1CDE6180进行查找，查找的结果处理是个难点。要点是，多点几次“再次扫描”，直到你看到左边栏里的地址，基本上不会有改变。
4、把第一个地址添加到列表：即017D8998，然后要对其进行“找出是什么改写了这个地址”的操作。这是个难点，一开始看不到什么提示。但是当你重新开始本局游戏后，你会发现里面有东西了：[edi+00000868]的提示，还有“要查找的地址指针的值可能是 017DB130”，离胜利不远了。
5、需要对地址017DB130进行查找，居然有2000多结果，但是不用担心，因为你多搜几次就会看到绿色的基址：007794F8出现了。
基址和偏移都找到了即[[[007794F8]+868]+5578]中存储的是阳光的值，[[007794F8]+868]+5578存储的是阳光的地址，这里值和地址不要搞混了，因为下一步Delphi编程中是读出阳光的值，写入阳光的地址，这也是个要点。
