/*----------------------------------------------------------------分割线----------------------------------------------------------------------*/D2Ptrs.h中：
FUNCPTR(D2COMMON, IsItemOfItemType, bool, __stdcall, (UnitAny* pItem, DWORD ItemType), 0x24430)
FUNCPTR(D2COMMON, AreCharmReqsMet, int, __stdcall, (UnitAny* pItem, UnitAny* pUnit), 0x287D0)
D2Vars.h中：
static const char* DEFAULT_CONFIG_PATH = "D2CharmLimit.ini";
static const char* SECTION_NAME = "D2CharmLimit";
struct Configuration
{
int BagLeft;
int BagRight;
int BagTop;
int BagBottem;
};
VAR(Configuration, Config)
void __fastcall Config_Load();
D2Vars.cpp中：
void __fastcall Config_Load()
{
INIReader ConfigReader(DEFAULT_CONFIG_PATH);
Config.BagLeft = ConfigReader.GetInteger(SECTION_NAME, "BagLeft", 0);
Config.BagRight = ConfigReader.GetInteger(SECTION_NAME, "BagRight", 0);
Config.BagTop = ConfigReader.GetInteger(SECTION_NAME, "BagTop", 0);
Config.BagBottem = ConfigReader.GetInteger(SECTION_NAME, "BagBottem", 0);
}
CharmInv.cpp中：
const DWORD DrawRedContinue = (DLLBASE_D2CLIENT + 0x95B47); //背包里不能用显示红色的地方
const DWORD NoDrawRedContinue = (DLLBASE_D2CLIENT + 0x95AD4); //背包里能用显示蓝色的地方
const DWORD InvCppAddress = (DLLBASE_D2CLIENT + 0xD476C);
void __declspec (naked) __stdcall CharmInventory()
{
__asm
{
test eax, eax
jne IsCharmInventory
retn 8
IsCharmInventory:
mov eax, //eax = UnitAny
mov eax, //eax = ItemPath
push ebx //此处为了读配置里的内容，以下同理
mov ebx, Config.BagLeft //ebx = 左边界
cmp ,ebx //pItem与eax+C也就是dwPosX限制分界左边相比较
pop ebx
jb NoCharmInventory //小于就返回
push ebx //同上
mov ebx, Config.BagRight
cmp ,ebx
pop ebx
ja NoCharmInventory
push ebx //同上
mov ebx, Config.BagTop
cmp ,ebx
pop ebx
jb NoCharmInventory
push ebx //同上
mov ebx, Config.BagBottem
cmp ,ebx
pop ebx
ja NoCharmInventory
mov eax,1 //可用
retn 8
NoCharmInventory:
xor eax, eax
retn 8
}
}
void __declspec (naked) __stdcall DrawRed()
{
__asm
{
test eax,eax //这里感觉没啥要解释的
je DrawRed1
push TYPE_CHARM
push ebx
call D2COMMON_IsItemOfItemType //参数在D2Ptrs.h中明确标出
test eax,eax
je NoDrawRed
mov eax,dword ptr ss:

文中已注释讲解
附：
D2Ptrs.h中的两Func自然不用多说
D2Vars.h和D2Vars.cpp中都是为了读写配置
此处有个BUG就是LC和GC的第一个格子所处位置有效
此BUG我会在以后尽量修复
/*----------------------------------------------------------------分割线----------------------------------------------------------------------*/
用法：
加载DLL利用大箱子或者是D2Win.dll
INI文件中四个参数很明显是定义边界的，但是需要注意的是第一格是从0开始的
此篇内容大概就酱紫吧
