  • EngineGUI Common GUI things for game tools
  • EntitiesMP All the entity logic

Building

To build Serious Engine 1, you'll need Visual Studio 2013 or 2015, Professional or Community edition ( https://www.visualstudio.com/post-download-vs?sku=community ).

Do not use spaces in the path to the solution.

Once you've installed Visual Studio and (optionally) DirectX8 SDK, you can build the engine solution (/Sources/All.sln). Press F7 or Build -> Build solution. The libraries and executables will be put into \Bin\ directory (or \Bin\Debug\ if you are using the Debug configuration).

Optional features

DirectX support is disabled by default. If you need DirectX support you'll have to download DirectX8 SDK (headers & libraries) ( http://files.seriouszone.com/download.php?fileid=759 or https://www.microsoft.com/en-us/download/details.aspx?id=6812 ) and then enable the SE1_D3D switch for all projects in the solution (Project properties -> Configuration properties -> C/C++ -> Preprocessor -> Preprocessor definitions -> Add "SE1_D3D" for both Debug and Release builds). You will also need to make sure the DirectX8 headers and libraries are located in the following folders (make the folder structure if it's not existing yet):

  • /Tools.Win32/Libraries/DX8SDK/Include/..
  • /Tools.Win32/Libraries/DX8SDK/Lib/..

MP3 playback is disabled by default. If you need this feature, you will have to copy amp11lib.dll to the '\Bin\' directory (and '\Bin\Debug\' for MP3 support in debug mode). The amp11lib.dll is distributed with older versions of Serious Sam: The First Encounter.

3D Exploration support is disabled in the open source version of Serious Engine 1 due to copyright issues. In case if you need to create new models you will have to either use editing tools from any of the original games, or write your own code for 3D object import/export.

IFeel support is disabled in the open source version of Serious Engine 1 due to copyright issues. In case if you need IFeel support you will have to copy IFC22.dll and ImmWrapper.dll from the original game into the \Bin\ folder.

Running

This version of the engine comes with a set of resources (\SE1_10.GRO) that allow you to freely use the engine without any additional resources required. However if you want to open or modify levels from Serious Sam Classic: The First Encounter or The Second Encounter (including most user-made levels), you will have to copy the game's resources (.GRO files) into the engine folder. You can buy the original games on Steam, as a part of a bundle with Serious Sam Revolution ( http://store.steampowered.com/app/227780 )

When running a selected project, make sure its project settings on Debugging is set to the right command:

  • For debug: $(SolutionDir)..\Bin\Debug\$(TargetName).exe`
  • For release: $(SolutionDir)..\Bin\$(TargetName).exe` And its working directory: $(SolutionDir)..\

Common problems

Before starting the build process, make sure you have a "Temp" folder in your development directory. If it doesn't exist, create it. SeriousSkaStudio has some issues with MFC windows that can prevent the main window from being displayed properly.
