    SadConsole

    SadConsole

    A .NET ascii/ansi console engine written in C# for MonoGame and XNA

    SadConsole is a generic library that emulates old-school console game systems. It provides command prompt-style graphics where one or more tile textures are used to represent an ASCII character set. Console's are made up of a grid of cells, each of which can have its own foreground, background, glyph, and special effect applied to it. While SadConsole is a generic library that doesn't provide any rendering capabilities, "host" libraries are provided that add renderers to SadConsole. The two hosts provided by this library are for MonoGame and SFML. SadConsole currently targets .NET 6, .NET 5, .NET Core 3.1, and .NET Standard 2.1. Uses graphical tile-based images to build out an ASCII-character font with support for more than 256 characters. Use more than one font file. However, each console is restricted to a single font.

    Svelto.ECS

    Svelto.ECS

    Svelto ECS C# Entity Component System

    Real ECS framework for c#. Enables writing encapsulated, decoupled, maintainable, highly efficient, data-oriented, cache-friendly, code without pain. Although the framework is platform agnostic (compatible with c# 7 and above and .net standard 2.0 and above), it comes with several Unity extensions. Svelto.ECS is easy to start with, but full of tricks for expert users. The hardest problem to overcome is usually to shift mentality from OOP programming to ECS programming more than using the framework itself. Svelto.ECS wasn't born just from the needs of a large team, but also as a result of years of reasoning behind software engineering applied to game development. Svelto.ECS hasn't been written just to develop faster code, it has been designed to help develop better code. Performance gains is just one of the benefits in using Svelto.ECS, as ECS is a great way to write cache-friendly code.

    TXna Game Engine

    TXna Game Engine

    XNA based game engine completely written in c#

    UPDATE 2014-06-01: As there are still lots of weekly downloads I need to clarify the TXna status. The Xna 3.1 based version is no longer developed, there are no commits for over two years. Instead a port to MonoGame is in progress. Please use the TXnaGE from the \branches\monogame folder! The monogame version is based on mongame 3.2.2 and has most of TXna features except: shadowmapping, modelscenenodes and instancing - those features are in development! Titanium Xna Game Engine is a Xna 3.1 based game engine written in c#. Complex scenes can be build in just few lines of code. The developer is free to combine TXna features and standard Xna techniques without any limitations. Please use the svn checkout or update feature to get the latest source and compile from source. The engine is not released frequently but only after major source updates. Chances are that by downloading a release you will get a rather old copy.

    ZAPH

    Tools and Z80 engine for creating adventure games. (RUST)

    This is an exercise in some advance programming topics using a text adventure as the central result. This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools.

    ZxSim

    API (C#) for simulating certain aspects of a ZX spectrum for porting.

    Initially this project is a showcase of my abilities to write code using C# and DotNet libraries, along with Design Patterns and SOLID techniques. The project itself is a bunch of libraries that make porting Spectrum games easier using C#. Originally I would use a popular UI and write code emulating the Z80. However over time those UIs would come out of favour or not compile on a modern OS, so the first aim is portability. The current examples will use Godot to display and control the game. Next is re-usability, broken up into separate scopes there is a natural layer of usage. Along with all this is some code to handle the original games data and to emulate some of the routines found in the original Z80, such as sprite blitting and room drawing. These will be broken into small plug-in classes which will allow future changes to use PNGs for the graphics instead of simple pixel drawing. This way the code can improve over time.
