** This document is a draft.

VastSpace is a 3-D realtime strategy game engine that I have been developing to test ideas I wanted to try.

• OpenGL-rendered universe including space stations, planets, stars and volumetric galaxies.
• Network games over TCP/IP in server-client model (in progress).
• Embedded scripting language for extensive modification.
• Dynamically linked MOD framework.
• HDR enabled for realistic level of lighting.
• Ships can hyperdrive to several lightyears distant solar systems.

Additional screenshots can be seen here

Windows client is tested in Windows 7/8 and 10. You'll need decent graphic boards that support OpenGL. Tested boards are Radeon HD6870, nVidia GeForce GT 650M and 1070 Ti.

Linux server must be able to build on most distributions. Fedora 8 and Ubuntu 16.04 LTS are tested.

• Git
• Visual studio 2017 or later

All dependent libraries except Bullet Dynamics Engine are included in this repository as source files.

Run

git clone https://github.com/bulletphysics/bullet3.git bullet
cd bullet
git checkout 2.88

on the console.

Open bullet\build3\vs2010\0_Bullet3Solution.sln with VC2017 or later. Upgrade toolset to v141 or later if requested.

With Visual Studio 2015, you will need to manually change platform toolset to "Visual Stuido 2017 (v141)" or later in the IDE property page. This is because premake4 does not support VS2015 yet.

You may need WTL (Windows Template Library) if you want to build the motion editor.

Linux server is a network server that can host game worlds to share among clients. The server hosted on Linux is called dedicated server and does not provide any graphics on the server side. The server can be managed while running by command-line interface.

Invoking gnu make will build the application. Gcc and g++ with C++11 support is needed. Gcc 4.8.2 is confirmed to build to some extent. Most distributions doesn't provide package managers that support gcc 4.8.2 but older versions. In such case (which is almost always the case), you must build gcc from source.

Also you could build with gcc Docker image (https://hub.docker.com/_/gcc) to get access to the newer version. If you have docker installed, simply run

docker run --rm -it -v $(pwd):/work -w /work gcc:latest

and build normally.

You'll need various external libraries:

• libpng
• The IJG's JPEG library (version 7 or later)
• zlib
• Bullet Dynamics Engine (version 2.76 or later)
• Squirrel Scripting Language version 3
• libogg
• libvorbis

All sources are included in the source tree except Bullet. You can choose the method to install these libraries; You can install from the distribution's package managers (yum or apt-get) or build from the sources.

If you want to build from source, run

./git-bullet.sh

on the same directory as this README.

Bullet Dynamics Engine's sources can be downloaded by the shell script svn-bullet.sh. A Subversion command line client and internet connection is required. BDE libraries are built as shared libraries because the extension libraries can link to them. The easiest way to incorporate BDE is to install it into the system, but if you have no system administrative privileges, you can set LD_LIBRARY_PATH environment variable to point to the libraries under your home directory when running the server.

I had been tracking history of the project with Subversion for long time, so you may see remnants of that age in places.

It took 1200 commits to become confident that Git is worth migrating from Subversion.

The first part of this software was written in 2004 and it was named Gltest, because that project's purpose is to test OpenGL features. As I added various ideas to that project, I end up thinking that creating a fully simulated space war game is great. Several years later, I switched the main language for the project to C++ from plain C. The project's name was changed to Gltestplus at that time. Subversion history starts since that time.
