Multiple shared injection for LeoEcsLite C# Entity Component System framework

Dependency injection for LeoECS Lite.

Tested on unity 2020.3 (not dependent on it) and contains assembly definition for compiling to separate assembly file for performance reason.

Important! Don't forget to use DEBUG builds for development and RELEASE builds in production: all internal error checks / exception throwing works only in DEBUG builds and eleminated for performance reasons in RELEASE.

"com.goodcat.ecslite.shared": "https://github.com/GoodCatGames/ecslite-multiple-shared.git"

As source

If you can't / don't want to use unity modules, code can be downloaded as sources archive from Releases page.

Integration to startup

var battleLog = new BattleLog();
IBattleLogView battleLogView = null;
#if DEBUG
   battleLogView = new BattleLogViewText(battleLog);         
#else
   battleLogView = new BattleLogViewHtml(battleLog);         
#endif

// If you use InjectShared() you cannot create systems with SharedCustom:
//    var systems = new EcsSystems (new EcsWorld(), new SharedCustom());
// You will get an exception.

var systems = new EcsSystems(new EcsWorld());
systems
    .Add (new System1())    
    .Add (new System2())    
    .Add (new BattleLogShowSystem())    
    // ...
    
    // InjectShared() methods should be placed after
    // all systems/worlds registration 
    .InjectShared(battleLog)
    .InjectShared<IBattleLogView>(battleLogView)    
    
    // InitShared() method should be placed after 
    // all InjectShared() methods
    .InitShared()        
    .Init();

public class BattleLogShowSystem : IEcsRunSystem
{
  [EcsInject] private readonly BattleLogViewBase _battleLogView;
  
  public void Run(EcsSystems systems)
  {
    _battleLogView.Show();
  }
}

// Getting Shared directly from systems
var shared = systems.GetShared<shared.Shared>();
var battleLogView = shared.Get<IBattleLogView>();
battleLogView.Show();
