gaztoof / gmod-sdk

A SDK with a built-in cheat for Garry's Mod.

GMod-SDK

This is a module for Garry's Mod that works based on a SDK.

I've spent the past few days reversing a few modules of the game, in order to get as many interfaces as I could that would be useful to make any type of internal module for Garry's Mod.

Note that this is still WIP!

This works in both x86, and x64.

I've uploaded every idb / dylib i've made while reversing the game, except x64 client.dll as it takes too much space for github.

The gui is an almost-perfect gamesense clone.

This also comes in with a built-in lua executor.

Usage

Compile as x86/x64 Release. Debug works too.

Get yourself an injector, select Garry's Mod, and inject the compiled .DLL into the target process.

If you did this right, the cheat should loaded.

Press INSERT to open the menu.

How to update

In case I stop working on this project, and you want to update it, feel free to fork this project.

Get the .dylibs using the game's macOs build SteamDepotDownloader, and make sure they're up-to-date when you compare them to the Windows build's interfaces.

Null functions can sometime be a pain, make sure they're not phasing out your entire interfaces. A single null function will stop everything from working.

Contact

You can contact me on Telegram, at t.me/@Gaztoof

This is my YouTube channel.

Made with

• IDA Pro - The software I used to reverse the game.
• VMT Dumper - The IDA script I used for dumping the VTables. I've found it on a forum and modified it.
• IMGui - The GUI is just modified pure ImGui.

gmod-sdk's Issues

access error

Exception thrown at 0x00007FFB66115AB8 (GMod-SDK.dll) in gmod.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFF8.

freezing issue

freezes game as soon as injected even know I am on 64x branch and multicore rendering disabled maybe the cheat hasn't updated yet to latest version of gmod.

[SOURCE] Auto Crouch-Jump

void CrouchJump(CUserCmd* cmd) { if (Settings::Misc::crouchJump && InputSystem->IsButtonDown(KEY_SPACE) && (!(localPlayer->getFlags() & FL_ONGROUND))) cmd->buttons |= IN_DUCK; }
Some Pasta For You :)

cant build

when i put the folder in visual studio it gives no option to build at the top or compile

Keyvalues

I see you have already tryed by evidence in tier1/Keyvalues.cpp

hiya gaztoof, when im joining a singlplayer game, i can not look around with my mouse, and the fps is around 20-30 when the normal amount is 120+ could u please help? cause is just impossible to play with it, maybe i will try to fix myself, but anyway

[Feature Request] Mark players with certain weapons using a different color?

TTT / Murder may need this feature. It involves:

1. Mark players with certain weapons using a different color.
2. Customizable weapon list. (maybe even save it to some file, idk)
3. Key to Reset markers.

help me pls

when i inject the game just closes out

idea: doubletap

Is there any possibility to add doubletap?
Barely saw any cheats in gmod with dt and looking at other source engine games where its being used (csgo, tf2), its pretty op and looking at the fact that gmod has way more weapons (because of addons) the use for it could be better.
Some info that might help 1 & 2 And also, it seems to be better to detour cl_move idk why

weird cyrillic symbols

i have an issue with cyrillic symbols when i type them. how to fix it?

Add NPC aimbot pls

Game crashes with it.

So, i've compiled the files in visual studio 2019, injected the DLL and the game crashed.
Version in console:

Protocol version 24
Exe version 2021.06.09 (garrysmod)
Exe build: 10:31:48 Jul  6 2021 (8277) (4000)
GMod version 2021.07.12, branch: x86-64, multicore: 1
Windows 32bit

I don't know what to do with this.

[GM:CallWithArgs - !ThreadInMainThread] EntityRemoved

Steps to reproduce

1. Join a DarkRP server (> 65 players)
2. Wait for 2 minutes or less
3. Crash

NOTES
It usually happens when one entity is removed (?) or one player disconnecting from the server

ScriptDetour Improvement

Unless I am misunderstanding this is really bad practice.

std::ifstream inFile;
inFile.open(detourDir.string());
if (inFile.good() && fileName != "runString.lua") {

	std::string content((std::istreambuf_iterator<char>(inFile)),
		(std::istreambuf_iterator<char>()));
	if (!strcmp(content.c_str(), fileContent.c_str()))return {};

	fileContent = content;
	return fileContent;
}
else {
	std::ofstream outDetourFile;
	outDetourFile.open(detourDir.string());
	if (outDetourFile.good())
	{
		outDetourFile << fileContent;
		outDetourFile.close();
	}
}

The problem is that you are saving every server file into the detour folder, in my original code this was not the intention.
The intention was for people to place the scripts themselves.
The reason for this is that when you have all the scripts pre placed in the detour folder you will no longer be getting any script updates from servers because there is already a script there.
A better solution for a runtime detour would be to instead have the detour scripts that users add append onto the original script. This way you can do stuff like rerouting functions without replacing the entire file.

OldEpicFunction = EpicFunction
EpicFunction = function()
    -- Do your own stuff
    OldEpicFunction()
    -- Do your own stuff
end

Something like this would probably work?

std::ifstream inFile;
inFile.open(detourDir.string());
if (inFile.good() && fileName != "runString.lua") {

	std::string content((std::istreambuf_iterator<char>(inFile)),
		(std::istreambuf_iterator<char>()));
	if (!strcmp(content.c_str(), fileContent.c_str()))return {};

	fileContent = fileContent + "\n\n" + content;
	return fileContent;
}

Crashing when inject

i am injected after game crashed how to fix*

antialias (idea)

you can put
pLine->SetAntialias(TRUE);
to the render initialization and everything lines will become more beautiful

Screengrab issues?

so I've joined this Russian server called "Wayzer's RP" and first of all the cheat wasn't rendering on the client side, but the feature like bhop was working fine.

After several hours I got banned for cheats (I had the FOV circle and the thing at the top left corner) and it was seen on the screengrab pic the admin shown me! 

"How strange?" I've thought, the entire cheat's UI could not be opened too! I could not fix this by myself

Still freezes game

I inject the dll into my gmod 64x with xenos 64x and it still freezes my game and I am on gmod 64 beta I freezes with anooying hev sound spamming Still not working I had to ctrl and alt delete to restart my pc cause I can't exit out there is two betas the chromium that is 64 but outdated and author 64x that is not outdated I dont know what's going on I dont know if the dll is causing the issue cause I downloaded from unkown cheats.

compiling issues

when im in debug mode it works but in release mode its saying that "executorFont" doesnt exist. ive tried commenting out the ifdef _DEBUG and endif but it still doesnt work.

proj issue

so if i change something in Present.h my compiler goes crazy lol
and i didn't touched anything in dllmain

Compile?

I'm confused, what do we compile it in?

Convar->GetFloat() not present.

could you please add this?

Random crash

1.20 Random crash for no reason so unusable and I don't understand it, thank you for your understanding

How do I use MaterialSystem->CreateMaterial

it only takes voids and not chars?

how do I hook cl_move?

#include "../globals.hpp"

typedef void(__thiscall* FN_cl_move)(float, bool);
FN_cl_move oCLMove;

void __fastcall hkCLMove(float accumulated_extra_samples,
#ifndef _WIN64
void*, // __fastcall does literally nothing in x64, so that's why we make it inactive
#endif
bool bFinalTick)
{

}

Here is what I go so far but it says:

Suggestion

Please add:
Anti OBS
Backtrack

Get rid of Present Pattern

As I see you are addicted to the Present pattern. Why not use EndScene + _ReturnAddress() ?

Project doesnt compile

hi this project doesnt compile its missing files ect

get rid of the "Untrusted" feature its useless

[GM:CallWithArgs - !ThreadInMainThread] EntityRemoved

HOW TO REPRODUCE STEPS

1. Launch GMOD
2. Join a mass populated server
3. wait 2 minutes
   

add netvars

please add these next update I wanna get m_angeyeangles for A resolver

Feature Request

You should render visuals by using the steam overlay device or the discord overlay device, it would prevent admins from screen capturing you.

cant rebuild or build

get these errors

Add Anti-OBS

Please add Anti-OBS. It would be nice for DarkRP because you can't clip anything without esp.

How do i compile this

In visual studio I keep getting errors

suggestion

add a esp option to find entitys so it highlights the entity that you selected.

fakeangles work but your movement breaks

so the movement fix doesn't seem to work for untrusted angles:

my cmd->viewangles.x = -180 for fakeup but my W and S keys are reversed the BackupCMD() function doesn't seem to be working?????

Game crashes randomly

Sometimes my game crash randomly while i'm playing. How i fix it?
