The previous version stopped working because the prologue of the TT chat code I'm hooking changed, seems to be because 4.1 uses a newer C++ compiler.

int TTChatHookAddress = 0;
int TTChatHookJMPAddress = 0;
int TTPrologueFuncCallAddress = 0;

bool ReadMemory(int Address, void* Buffer, int Size)
{
        bool ret = 1;
        DWORD OldProtect;
        HANDLE Process = OpenProcess(PROCESS_VM_READ | PROCESS_VM_WRITE | PROCESS_VM_OPERATION, false, GetCurrentProcessId());
        VirtualProtectEx(Process, (LPVOID)Address, Size, PAGE_EXECUTE_READWRITE, &OldProtect);
        if (!ReadProcessMemory(Process, (LPVOID)Address, Buffer, Size, NULL))
        {
                Console_Output("Reading process memory adress 0x%x failed\n", Address);
                Console_Output("GetLastError() = %d\n", GetLastError());
                ret = 0;
        }
        VirtualProtectEx(Process, (LPVOID)Address, Size, OldProtect, NULL);
        CloseHandle(Process);
        return ret;
}
 
bool WriteMemory(int Address, const void* Buffer, int Size)
{
        bool ret = 1;
        DWORD OldProtect;
        HANDLE Process = OpenProcess(PROCESS_VM_READ | PROCESS_VM_WRITE | PROCESS_VM_OPERATION, false, GetCurrentProcessId());
        VirtualProtectEx(Process, (LPVOID)Address, Size, PAGE_EXECUTE_READWRITE, &OldProtect);
        if (!WriteProcessMemory(Process, (LPVOID)Address, Buffer, Size, NULL))
        {
                Console_Output("Hooking address 0x%x failed\n", Address);
                Console_Output("GetLastError() = %d\n", GetLastError());
                ret = 0;
        }
        VirtualProtectEx(Process, (LPVOID)Address, Size, OldProtect, NULL);
        CloseHandle(Process);
        return ret;
}
 
void Install_Hook(char OpCode, int Addr, int Glue, char *Padding)
{
        int HookAddress = Addr;
        int Offset = Glue - HookAddress - 5;
        WriteMemory(HookAddress, &OpCode, 1);
        WriteMemory(HookAddress+1, &Offset, 4);
};
 
int Calculate_Address_From_Displacement(int JMPStartAddress)
{
        char OpCodes[5];
        int Displacement, Address;
 
        ReadMemory(JMPStartAddress, OpCodes, 5);
        Console_Output("BYTES READ: 0x%x 0x%x 0x%x 0x%x 0x%x \n", OpCodes[0], OpCodes[1], OpCodes[2], OpCodes[3], OpCodes[4]);
 
        memcpy(&Displacement, OpCodes+1, sizeof(char)*4); // OpCodeBuffer+1 or we'll also read the JMP opcode
 
        Address = JMPStartAddress + 5 + Displacement;
        return Address;
}

bool _cdecl Private_Chat_Hook(int PlayerID, int Type, wchar_t *Message, int TargetID)
{
	if (TargetID == -2 || Type != 2) { return true; } // Only trigger on valid private chat

	Console_Output("PlayerID = %d, TargetID = %d, type = %d, Message = %S\n", PlayerID, TargetID, Type, Message);

	return false;
}

void _declspec(naked) PrivateChatHook_Glue()
{
	_asm
	{
		push esi		
		mov eax, esi
		mov esi, ecx // save ecx

		push [ecx+06C0h] // arg 4, TargetID
		push [ecx+06BCh] // arg 3, Message
		push [ecx+06B8h] // arg 2, Type
		push [ecx+06B4h] // arg 1, PlayerID
		call Private_Chat_Hook
		add esp, 16;

		mov ecx, esi // restore ecx
		
		test al, al
		jz Block_Private_Chat
		
		call TTPrologueFuncCallAddress
		jmp TTChatHookJMPAddress

Block_Private_Chat:
		pop esi
		retn
	}
}

// install function, OnLoadGlobalINISettings is a good place to install, the plugin constructor doesn't work
void TriggerbotAntiCheat::OnLoadGlobalINISettings(INIClass *SSGMIni)
{
	TTChatHookAddress = Calculate_Address_From_Displacement(0x004B5C10); // Hook from  cCsTextObj::Act(void)
	TTChatHookJMPAddress = TTChatHookAddress+8;
	TTPrologueFuncCallAddress = Calculate_Address_From_Displacement(TTChatHookAddress + 3);

	Install_Hook('\xE9', TTChatHookAddress, (int)&PrivateChatHook_Glue, "");
}

Spying on private chat again? You should apply for a job with the NSA, or the equivalent in your country Sarcasm

well we just use it to block people from PMing each other when !mute-ed because !mute only blocks public chat by default

not very useful when someone complains about being PM'd mean things about their mother ;>

You can use it for keyhooks and checking certain scripts.dll netcode too.

The "!vote yes"/"!vote no" keyhook is actually in both SSGM and Dragonade, you can just manually remove the keyhook entirely or edit it to take out that annoying chat message if you wish.
