Moving Mod And Source Files

From Valve Developer Community
Jump to: navigation, search

The Source SDK sets up a mod that to be worked on the machine that the wizard ran on. This setup includes creating configuration setups for the SDK Tool, Hammer, and in Visual Studio Solution files. For any reason you need to move from one to computer to another, it becomes an issue to continue working. This includes situations of just moving from one machine to the next (such as moving from an academic lab computer to a computer at home) as well as any source control situation.

The goal of this document is to explain each part that needs to move and how to reset the configuration settings to continue working.

Set the Working Directory for Your Source Files

The Create a Mod Wizard will ask you to provide or create a folder location. This folder is your source directory. The SCR directory contains all of the source code for the mod. The other folders created are for the raw and conversion files for maps, models, and textures. These files are the team's work files, and are not given to users whom will play your mod.

This folder can be be moved at will, provided the information below is correct as well.

Set The Game Directory for Your Mod

The folder that is created under ...\Steam\steamapps\SourceMods for your mod is called the Game directory. The name of this directory is the name that was supplied during the create a mod wizard. This is the directory that is shared with other users whom will play your mod. This directory holds other important directories, such as the ones for DLL and MAPS.

VS will copy the finished client and server DLL's to the following directory.


The folder to where map bsp files will be copied to will be the following directory.


Configure File Copying in Visual Studio Solution

Right-click > Properties on the Server and Client projects. You will need to do this for both the Release and the Debug configuration; four times in all.

  1. Navigate to Configuration Properties > Build Events > Post-Build Event.
  2. Click on Command Line, then click on the ... button that appears on the right.
  3. Replace the contents of the new dialogue with the first code block below.

Warning.png Warning: Remember to fill in the actual target destination instead of <YOUR MOD PATH>.
Note.png Note: The "<YOUR MOD PATH>" is the path of your "..\SteamApps\SourceMods\<Your Mod>" directory, and not the directory of your Visual Studio Project.

Command Line

if exist "<YOUR MOD PATH>\bin\$(TargetFileName)" attrib -r "<YOUR MOD PATH>\bin\$(TargetFileName)"
copy "$(TargetDir)"$(TargetFileName) "<YOUR MOD PATH>\bin\"
if exist "<YOUR MOD PATH>\bin\$(TargetName).pdb" attrib -r "<YOUR MOD PATH>\bin\$(TargetName).pdb"
if exist "$(TargetDir)"$(TargetName).pdb copy "$(TargetDir)"$(TargetName).pdb "<YOUR MOD PATH>\bin\"


<YOUR MOD PATH>\bin\$(TargetFileName);<YOUR MOD PATH>\bin\$(TargetName).pdb

Warning.png Warning: It is possible that you have a corrupted bin file instead a bin folder at your Steam mod path. If this occurs, delete it and recompile or create your mod project again.
