Search:

	if (fDstRot < 0.0f)
		fDstRot = 360 + fDstRot;
	else if (fDstRot > 360.0f)
		fDstRot = fmodf(fDstRot, 360.0f);

 

Add it upper any of:

Only warning:

	CPythonCharacterManager& rkChrMgr = CPythonCharacterManager::Instance();
	CInstanceBase* pkInstMain = rkChrMgr.GetMainInstancePtr();

Close game client:

    CPythonCharacterManager& rkChrMgr =CPythonCharacterManager::Instance();
    CInstanceBase* pkInstMain = rkChrMgr.GetMainInstancePtr();
    if(pkInstMain){
        if(!pkInstMain->IsGoing()&& pkInstMain->__CanSkipCollision()){

Better than https://metin2dev.org/board/index.php?/topic/8508-serverside-anticheat-guide/ ?

Serverside solutions always better but have some problems detect for wallhack in serverside

For the present, This solution better

[Shisui 486]

Can you make this function say the player name?

CPythonCharacterManager& rkChrMgr = CPythonCharacterManager::Instance();
    CInstanceBase* pkInstMain = rkChrMgr.GetMainInstancePtr();
    if (pkInstMain){
        if (!pkInstMain->IsGoing() && pkInstMain->__CanSkipCollision()){
            CPythonChat::Instance().AppendChat(CHAT_TYPE_NOTICE, "Wall hack !");
            return false;
        }
    }

This function for only for him no one else. if you want notice for all players you can use and modify sendhack function

 

In input_main.cpp

void CInputMain::Hack(LPCHARACTER ch, const char * c_pData)

 

You can use notice all like this

	char nbuf[200];
	sprintf(nbuf, "%s in %s named player", buf, ch->GetName());
	SendNotice(nbuf);
