EcsRx is a reactive take on the common ECS pattern with a well separated design and support for dependency injection (if you want it).
We have now also got a real-world example to view @ grofit/ecsrx.roguelike2d
There is also a simple example of a plugin to view @ grofit/ecsrx.buffs
There is now a supplementary databinding framework for unirx @ grofit/bindingsrx
The core framework only depends upon UniRx however the unity bridge part of the framework depends upon zenject, however feel free to create your own unity bridge to consume the core framework if you do not want the dependency.
- Simple ECS interfaces to follow
- Fully reactive architecture
- Favours composition over inheritance
- Adheres to inversion of control
- Lightweight codebase
- Built in support for events (raise your own and react to them)
- Built in support for pooling (easy to add your own implementation or wrap 3rd party pooling tools)
- Built in support for plugins (wrap up your own components and systems and share them with others)
- Simple unity conventions to follow (if you dont like it, easy enough to roll your own)
- Built in support for editor viewing and editing of components
- Built in support for dependency injection via Zenject
- Lots of extension and architectural helpers to help MonoBehaviours interact with the core framework
- Plays nicely with scene first style setups
You can take the unitypackage installation file from the relevent release, there are 2 files.
The Core package contains the pure project files which are required for the framework to function.
The Unity package contains a wrapper around the Core framework and some unity helpers, this will be built upon going forward.
- Install both the above packages
- Install Zenject
- Install UniRx
Then assuming you are using the unity bridge project just look at one of the example projects and follow the conventions in there. You will ultimately need to create a
SceneContext from Zenject then register the
DefaultEcsRxInstaller and any of your own installer classes. Then create an your own implementation of
EcsRxApplication where you can setup your systems and entities.
Much like any other ECS implementation you have the notion of entities (
IEntity), components (
IComponent) and systems (
ISystem), although there are a few types of systems which you can implement based upon your needs, check out the docs folder for more information on these subjects as its more than just a 1 liner.
If you want to run the examples then just clone it and open the unity project in the
src folder, then run the examples, I will try to add to as the library matures, but there are 2 examples there currently.
There are also a suite of tests which are being expanded as the project grows, it was written with testability in mind.
See the docs folder for more information. (This will grow)
This was not designed with performance in mind, it should be performant enough for most scenarios, and given its reactive nature and decoupled design you can easily replace implementations at will, but as lots of people love performance metrics etc, I have none and have put performance secondary to functionality.
