What is Rootex?

Find the upcoming features and the game's public Trello board here!

This game will be a product of a join effort of SDSLabs and Design Studio.

Features

• Based on the popular Entity-Component-System architecture
  • Allows performance benefits due to better CPU cache usage. However over-optimizations are not the goal
  • Uses an impure ECS where components can have functions
• Full editor GUI implemented in ImGui
  • Similar interface as other popular game engine editors for added familiarity and ease of use
  • Readable asset files (100% JSON)
• 3D DirectX 11 renderer
  • Dynamic and static Phong-model lighting
  • High resolution textures for Diffuse, Normal, Specular and Light mapping
  • Post processing effects like gaussian blur, bloom, Adaptive SSAO, FXAA, including ad-hoc sepia, black-and-white, tonemapping
  • Mildly configurable CPU based particle effects
  • Effekseer Particle effects integration available for high quality VFX
  • Environment effects like Sky sphere, sky reflections, refractions and depth fog
  • Supports basic transform and skeletal animations
  • Automatic LOD (level-of-detail) generation for 3D models and animations
  • Custom materials using custom HLSL shaders
  • And few more things...
• RmlUi integration which allows writing/debugging UI overlays in an HTML/CSS-like language and Lua
• Physics engine powered by Bullet Physics 3, allows an easy-to-work-with interface for making physics simulations
• OpenAL-Soft based audio engine supporting 3D attenuation and stereo sound
• Lua scripting engine with functionality exposed for easy game curation
  • Uses an object-oriented approach with Lua scripting for making intuitive scope declarations and reducing garbage generation
  • Lua debugger integration
  • Equipped with a tweening API provided by flux
• Applies the event-based programming paradigm for better maitainability of game code
• Being developed for an actual game
  • Some game-specific features are also present like the Inky Lua runtime integration which allows writing dialogue in the Ink language and running them inside Rootex.
• Documentation

Why is Rootex?

Rootex is the direct successor of Rubeus, our 2D Game Engine. Rubeus Engine is not being maintained and is being preserved. Newer features will only be planned for Rootex. The game being developed will be announced soon as well.

How do I use Rootex?

1. Install Visual Studio 2019 or Visual Studio 2017, CMake build system.
2. Install Visual Studio Desktop C++ development pack (or anything similar, since C++ is no longer a default language since at least Visual Studio 19)
3. Run generate_cache.bat /19 for VS 2019 or generate_cache.bat /17 for VS 2017.
4. Use build.bat to build Rootex.

Assets Workflow :

1. Assets are stored in separate repositories and added as git submodules. The testing assets are stored at https://gitlab.com/sdslabs/rootex-assets while the assets for the game are stored at https://gitlab.com/sdslabs/rootex-game.
2. The assets.bat script has two subcommands to make switching of the submodules between the testing and game repository easier. Use assets.bat assets-test to switch to the test repository and assets.bat assets-game to switch to the game repository. The submodule will have two remote urls set. The origin points to the HTTPS url while upstream points to the SSH url.
3. You can also add your own repository as an assets submodule. Use assets.bat assets-custom <url> for that. If setting a custom url, use an HTTPS url here and then set an SSH remote afterwards.

WARNING : Running assets.bat will delete the game/assets/ folder. Be sure to backup any unsaved progress before running it.

Now you can start reading the documentation and build games on Rootex!

NOTE: If you get the error dxgidebug.dll not loaded while opening the Rootex Editor, install Graphics Tools by following this guide.

How can I contribute?
