Lightweight and cross platform game engine hobby project.

KESTD-Ronin

What is it?

KESTD-Ronin is a lightweight, experiment friendly and cross platform game engine developed by Mario Sieg.

What is the usage?

The engine and the integrated editor "AutoTec" can be used to create fully features 3D apps, simulations and games. The engine is designed to be very easy to use and flexible - hence "experiment friendly", because it is also often used to test algorithms, rendering techiques or physics. Besides from games it can also be used to create visualizations of all kinds; for demos, architecture and art. Also it is currently used by me for various projects and demos.

What languages?

The main engine is written in modern C++ 20. For general and gameplay scripting C++ or the very flexible Lua language can be used.

Why use KESTD-Ronin over other engines?

The main advantages:

• ✴️ Learning
• ✴️ Experimenting
• ✴️ Very lightweight
• ✴️ Flexible and extendable
• ✴️ Fast, low memory usage
• ✴️ Modern C++ 20 and idioms
• ✴️ Lua scripting
• ✴️ Python scripting

Platforms:

• ✅ Windows
• ✅ Linux
• ✅ Mac

Implementation:

• ✅ Direct3D9
• ✅ Direct3D11
• ✅ Direct3D12
• ✅ Vulkan
• ✅ OpenGL
• ✅ OpenGL ES
• ✅ Metal
• ✅ WebGL
• ✅ Multithreaded rendering
• ✅ SSE, AVX
• ✅ Lua (Embedded Interpreter)

There is still some code missing. I'm currently making a big cleanup and refractor then the code will appear!

kestd-ronin's Issues

Make a cross platform launcher for KESTD Ronin

Create a cross platform launcher for KESTD Ronin where you can install updates,
install different engine versions. It also should have some project, team and asset management.

Create a crash hander library for KESTD

Move AutoTec from KESTD to own Project.

AutoTec will me moved to own project. It will also be no more included in KestdRonin.dll -> it will
get it's own dll "AutoTec.dll". This step is required to make KESTD Ronin more cleaner and to run it on consoles,
because AutoTec requires access to file dialogs and more stuff a console does not have so KESTD Ronin won't compile on consoles currently. With a seperate "AutoTec.dll" we can just not ship it with the console.
I will also add a KestdRonin.exe, which contains all native entries. This is also the executeable
the game will be. It will get the game icon and name and must be run in a valid working directory.
So in the next time we will have new binary files:

/Bin/
AutoTec.exe <- PC, Mac, Linux only
AutoTec.dll <- PC, Max, Linux only
KestdRonin.dll <- All platforms
KestdRonin.exe <- All platforms

Create night time manager and implement fast logging library

Update the logger to use rolling logs and create a new logfile everyday at night like 3:00, 4:00 or 5:00 am.
Also the engine could do some work during night like database cleanup, files sorting, analyzing and cleaning up.

Analyze dependencies and system requirements

Analyze what kind of hardware KESTD Ronin needs:
CPU
GPU
RAM

And on which runtimes and 3rd party installs it depends!
