It's easy:

I can't understand how to make it work, you could guide me a little please, since I don't understand much c++

Hello @noanshadow!
 

You have to compile this code into DLL library in Visual Studio. Send your Game.exe, I will help you with it.

Thx V3ct0r!

Hello @noanshadow!

 

Here you are

 

1) Install mod loader for your client;

2) Put the file "pkodev.mod.mobsize.client.13x_3.dll" to the "mods" folder;

3) Start the game.

 

Project for Visual Studio 2019 Community is included in the archive. I think it also will be compatible with 2022 version.

 

You can change the size of necessary monster by it's ID in void* __fastcall hooked_AddCharacter(void* This, void* NotUsed, unsigned int nScriptID) function, for example:

void* __fastcall hooked_AddCharacter(void* This, void* NotUsed, unsigned int nScriptID)
{
	// Check that monster is the Piglet
	if (nScriptID == 237)
	{
		// Change Piglet's size
		newScaleAddr.SetNewScaleParam(2.5f, 2.5f, 2.5f);
	}
	else
	{
		// Do not change the size
		newScaleAddr.SetNewScaleParam();
	}
		
	return AddCharacter(This, nScriptID);
}

Do not forget to rebuild the mod after the changes.
