In order to successfully build Multi Theft Auto from source, it is necessary to perform a number of steps, which we will explain below.

Please read the instructions carefully and do not skip parts of it, if you have no experience.

Prerequisites

Compiling the Multi Theft Auto client is only supported on Windows 10.

Make sure you have the following software and SDKs installed:

Visual Studio 2022

  1. Download Microsoft Visual Studio 2022 - make sure you get the Community Edition, that one is free.
  2. On the installation checklist, make sure you tick these 2 items:
    1. Desktop development with C++
    2. Optional component C++ MFC for latest v143 build tools (x86 & x64)

If you don't enable MFC, you will get the following error: cannot open include file 'afxres.h'.

If you've made a mistake, you can run the Visual Studio Installer app to modify your current installation. There is no need to uninstall and reinstall.

Microsoft DirectX SDK

NOTE: Restart your computer after installing Microsoft DirectX SDK, because otherwise the environment variable DXSDK_DIR won't be available yet. After restarting it re-run create-projects.bat

Cant find d3dx9.h
Add the $(DXSDK_DIR)Include; to the VC++ Directories in DirectX9GuiRenderer, GUI and Client Core projects. You can find the VC++ Directories list by selecting a project, then pressing the shortcut ALT + ENTER (without the +), then under the 'Configuration properties' you can find 'VC++ Directories', and in there you can find the 'Include Directories' field, click on it and add ;$(DXSDK_DIR)Include; at the end of it. Note: You need to do the same thing in Release mode as well

Cant find d3dx9.lib
Do do same as in the error above, but instead of ;$(DXSDK_DIR)Include; you must add ;$(DXSDK_DIR)Lib/x86; to the Library directories field Note: You need to do the same thing in Release mode as well

S1023 Error
"S1023" error when you install the DirectX SDK (June 2010)

Cannot open source file "xxx.h" after upgrading to Visual Studio 2022
If you've just upgraded to Visual Studio 2022 and were working on MTA using a previous version, you may receive errors about header files not being found (stdio.h, stddef.h, etc) when building the project.

Make sure you have the latest Windows 10 SDK installed (via the Visual Studio Installer) and restart your PC.

If that doesn't work - close Visual Studio, go into the `Build` folder (where your mtasa-blue is located) and delete the `.vs` folder. Start Visual Studio and everything should be fixed.

Git Client

Git logo.png

If you would like to contribute to MTA, you should install Git. This will allow you to collaborate with us by creating branches and pushing to your own fork. If you are not comfortable with the command line, we recommend you to download and install GitHub Desktop.

If you only want to compile the source code and are not interested in contributing to MTA, you can download the source directly (see below).

Getting the latest source code

To get the latest code, you will have to download the latest copy of our Git repository.
We recommend cloning the repository in your Git client because you can pull any updates from there easily.

Compiling the code

  1. Execute the script win-create-projects.bat
  2. Open the solution file MTASA.sln in the Build directory
  3. If you are asked to upgrade the project, click Cancel
  4. Select Debug - Win32 configuration in Visual Studio, then press Build > Build Solution... (may take some minutes)
  5. Execute the script win-install-data.bat

Running the software

Running the client

You can start your client in the Bin directory. You might find there a Multi Theft Auto.exe and/or Multi Theft Auto_d.exe executable. The _d suffix indicates a debug build of the software.
Furthermore, you can also run your client inside the debugger from Visual Studio if you want to investigate a stack trace or set breakpoints in interesting code regions (read more in the section Debugging below).

Running the dedicated server

If you already have run step 5 (Install resources) in Compiling the code to install resources then you can go to Starting the server.

Installing the latest resources

If you want to run the Multi Theft Auto dedicated server, you will have to install the required resources. These are required because they implement the most basic functionality (e.g. spawning players) in order to play.

Our official resources repository is hosted on GitHub. You can download the latest resources from there or download a zipped version. Make sure that you have the latest resources package.

Starting the server

To run the server, open the MTA Server.exe executable in the Bin/server directory. The _d suffix indicates a debug build of the software.
You can also run the debug build MTA Server_d.exe with the Visual Studio Debugger (as of writing, you can do that by right-clicking on the Server's Launcher project and selecting Start a local instance in the Debugger menu), but you can also attach to a running debug build MTA server (see more in the section Debugging below).

Debugging

If you already compiled the code in the Debug configuration then continue reading, if not, then go up to Compiling the code and follow the steps for a Debug build.
You can either launch MTA yourself and attach any debugger you want to use (also applies to the Visual Studio debugger) or you start a local debugging session in Visual Studio.

How to enable breakpoints

If you choose to run MTA with Visual Studio then you should also attach the debugger to the executable gta_sa.exe (press CTRL + ALT + P in Visual Studio) - otherwise, your breakpoints will not work for anything besides the MTA Launcher project.

Extending timeout duration

When you use breakpoints during debugging, you may get kicked by the server due to timeout, because the client is frozen. To prevent this, create the timeout.longtime file in your Bin/server/ directory. The content of the file is the new timeout duration in seconds, so make sure you type a huge number in there. If you keep the file empty, the timeout will be set to 120 seconds.

ReAttach for Visual Studio

You can use ReAttach to re-attach the debugger to the gta_sa.exe executable whenever you start your local debugger in Visual Studio.
