# Auto Injections for [DragonECS](https://github.com/DCFApixels/DragonECS)
|
|
|
|
| Languages: | [Русский](https://github.com/DCFApixels/DragonECS-AutoInjections/blob/main/README-RU.md) | [English(WIP)](https://github.com/DCFApixels/DragonECS-AutoInjections) |
|
|
| :--- | :--- | :--- |
|
|
|
|
The extension is designed to reduce the amount of code by simplifying dependency injection by doing injections automatically.
|
|
> **NOTICE:** The project is a work in progress, API may change.

# Versioning
|
|
DragonECS uses this versioning semantics: [Open](https://gist.github.com/DCFApixels/c3b178a308b411f530361d1d56f1f929#versioning)
|
|
|

# Code Example
|
|
```csharp
|
|
class VelocitySystemDI : IEcsRunProcess
|
|
{
|
|
class Subject : EcsSubjectDI
|
|
{
|
|
[ExcImplicit(typeof(FreezedTag))]
|
|
[Inc] public EcsPool<Pose> poses;
|
|
[Inc] public EcsPool<Velocity> velocities;
|
|
}
|
|
|
|
[EcsInject] EcsDefaultWorld _world;
|
|
[EcsInject] TimeService _time;
|
|
|
|
public void Run(EcsPipeline pipeline)
|
|
{
|
|
foreach (var e in _world.Where(out Subject s))
|
|
{
|
|
s.poses.Write(e).position += s.velocities.Read(e).value * _time.DeltaTime;
|
|
}
|
|
}
|
|
}
|
|
```

<summary>Same code but without AutoInjections</summary>
