This is an application that has been developed as an multiuser server based simulation core for browser games, but has evolved to an server based application core system.
Do not hesitate to ask for more information.
I came to the conclusion that I will never be able to make any use of this code, anyways I believe it contains many good ideas. The code is somewhat old and has run through many iterations until it has come to the state it is now.
One of the earlies file headers I have seen are from January 2011. So this code base has been created before C++-11 standard was widely used. Such sources are probably even some years older.
So think of it if you come along some weird code fragments, e.g these file-access classes that could now be changed to C++ standard implementations.
Documentation is of course not existing. I am still available to fix this is someone has interest in using the software.
- Simulation Core
- Time descrete updates
- Event based updates
- Simulation Objects can be loaded on-demand and are unloaded after some timeout.
- Web-Server
- Uses a shared library to create dynamic content (somewhat fast)
- From the shared library messages can be send to the simulation core
- Requests that wait for a response message will be parked. So no blocking here for other request.
- WebSocket server
- WebSocket client code.
- PostgreSQL database access
- In general the simulation acts like a in-memory-database.
- So updates on simulation objects are written in the background to the DB.
The only existing support tool is a code generator for UML tools that can be used to maintain the simulation. The generator creates tons of code for simulation objects. So even it is possible to write the simulation manually I would not suggest doing so.
On the other hand you may need that freedom.
