Requirements

Getting it working

Set STEAM_ROOT

First, you'll need to set up the environment variable STEAM_ROOT to tell VS where your Steam installation lives. This is usually C:\Program Files (x86)\Steam in Vista or 7.

To add the variable:

1. Start, Right-click on Computer, choose Properties
2. Choose Advanced System Settings
3. Select the Advanced tab, choose Environment Variables...
4. Under "User variables for (you)", choose New...
5. Enter STEAM_ROOT as the variable name, and the path to your Steam installation as the value, without a trailing \
6. Choose OK
7. Restart VS if it was running, so it will pick up the added environment variable

Building

Open the VS solution file /src/tryhard.sln. Make sure that client is set as the default project (it should be bolded). You should be able to hit F5 (or go to Debug -> Start Debugging). The files should be built automatically.

If you want to build the project outside of VS, you'll need to follow these steps:

1. You may need to define VS's environment variables:

   call "path/to/vs/install/folder/vc/vcvarsall.bat" x86

2. cd to the /src directory in your github repo
3. run msbuild:

   msbuild tryhard.sln
