Hello.

I'm looking for new plugin ideas.

And I have a question. Is there any client-server plugins that allow you to control all keyboard buttons in you Pawn code(server side)?

Alf21 · 13.01.2018, 12:00

You can use some dll injections or hooks, but it only works clientside on localhost.
There is a possibility to do this. You need to write an extension with memory hacking, but thats not recommend and to display every pressed button is like creating a trojan as well as it results in an huge network drain.
If you consider it, create a hook clientside that is called everytime a key is pressed. Send the key as flag byte as RPC to the server and hook the RPC serverside. Create some queries to reduce the network drain. e.g. just record the keys if the user is in a dialog or smth like this.

There is the better way (sockets).
But before that, I need to know, if plugins like this exist.

How do you think sockets can help. That results in a much more huger network drain and performance drain. So on you also need client- and serverside plugins to hook these actions. If you can record the keys with the help of dlls, there is no memory hacking anymore. But for that there is a greater comsumption all in all.

If you pay attention to ingame Textdraw-Editors, you can find some ms dll files that hook the keys and make it possible to use the keys clientside on localhost.
Try to find these files and understand how it works and how you can use it

Sockets help me to send information from client to server side.
Yes, I meant client-server application, such as Textdraw-Editors. I think, there won't some big problems with network.
It also needs some network tests, but I think, it will be all fine.

Do you know some client-server plugins with this release?
I don't want to create, what was created before

It's very difficult to create such plugin with hacking SA:MP client side.
And also there can be some problems with every new SA:MP version.

In the category "details" you can see that the creator uses new hotkeys.
This is a result of both files (iTD.dll, msvcr100.dll).
I never did something with msvcr dlls, but i believe this is a detection to start the iTD.dll (https://msdn.microsoft.com/en-us/library/bb918180.aspx CRT startup like a hook).

if you know how the author created his iTD.dll, you just need to implement you socket solution in that and hope, that other people will download clientside files ^^

Okey, thank you very much. I will check this plugin! It will help to realese my idea.

Will you install such client plugin to get some more server capabilities?

If you want that people download it, you need a performance test to show that there are no issues and you need to make the code open-source. Otherwise the most amount of people could believe that it is a trojan or virus.

So sure, i would test it but it should be open-source - sorry :/. Try GitHub.

I want to do open-source project. In GitHub. I don't have own samp-server.
It's only for my own practice in programming

KrYpToDeN · 13.01.2018, 12:48

So, there aren't such open-source plugins for windows+linux at the moment?

~~Kaperstone~~ · 13.01.2018, 12:55

There was an attempt for it and it failed + locked.

You can read the comments why.

If this data is read out from GTA game memory not samp client memory, then new version does'nt matter, gta game exe will remain the same, and if memory location is fixed address, its quite easy to read.

Anyway its a bad way to do that.

Then maybe you can start by trying to read it out from the memory (using CheatEngine for example...).
What prog. language you are using?

Alf21 · 13.01.2018, 13:51

I agree. But i believe a first try would be very great. I would use it.

Here is my old code of getting the keys (for that you need to hook the window instance of gta-sa(mp)):

Keyboard.h

Код:

#pragma once
namespace Keyboard {
	void WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam);
	void AddKey(BYTE byteType, BYTE byteKey);
};

Keyboard.cpp

Код:

#include "Keyboard.h"
//... includes like LiteRPC for memory hacking UDP connection of SAMP - instead use ur socket

bool CaptureKey[KEYBOARD_MAX_KEYS] = { 0 };

void Keyboard::WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam) // call this on WndProc of your GTA-SA(MP) instance
{
	switch (uMsg)
	{
		case WM_KEYUP:
		{
			if (wParam < 0 || wParam > KEYBOARD_MAX_KEYS)
				break;

			BYTE byteKey = static_cast<BYTE>(wParam);

			// get the char of pressed key
			DWORD dwProcessId = GetWindowThreadProcessId(hWnd, NULL);
			HKL dwhkl = GetKeyboardLayout(dwProcessId);
			BYTE vks[KEYBOARD_MAX_KEYS + 1];
			WORD w;
			GetKeyboardState(vks);
			int result = ToAsciiEx((unsigned short int)wParam, HC_ACTION, vks, &w, 0, dwhkl);

			if (CaptureKey[byteKey])
			{
				DEBUG_OUT("SENDING KEY %x with char %c\n", byteKey, (char)w);
				RPCS::Keyboard::SendKey(byteKey, w); // RPC sending key, you could use ur socket
			}

			break;
		}
	}
}

void Keyboard::AddKey(BYTE byteType, BYTE byteKey) // such a register to not spam the key
{
	if (byteKey < 0 || byteKey > KEYBOARD_MAX_KEYS)
		return;

	DEBUG_OUT("ADDING KEY %x\n", byteKey);

	switch (byteType)
	{
	case 0: // register
		CaptureKey[byteKey] = true;
		break;
	case 1: // unregister
		CaptureKey[byteKey] = false;
		break;
	}
}

and my keyids with defines to handle more easier:

Код:

#define KEYBOARD_MAX_KEYS 255                   // Maximal amount of added keys

// VK_[KEYNAME]: Defines of Keynames with hexadecimal of them (0-255)

If you dont know how to inject this file to auto execute on start samp or gta sa, try dll injection or cleo. I would recommend dll injection like input.dll (DirectX Hook / Injection).
