Zenject与UniRx结合实现跨线程通信Signal

• 修改Zenject下ProfileBlock.cs源码, 取消有关UnityEngine.Profiling.Profiler的代码.
• 然后使用Zenject的Signal:

   // 定义Signal
    public class TestCrossThreadCommEvent : Signal<string, TestCrossThreadCommEvent> { }

   // Install Signals
     Container.DeclareSignal<TestCrossThreadCommEvent>();

 // 启动线程
     tth = new Thread(() =>
     {
         while (true)
         {
             Thread.Sleep();
             _crossThreadCommEvent.Fire("fire not in main thread");
             //_unityEvent.Invoke();
         }
     });
     tth.Start();
     // UniRx
     _crossThreadCommEvent.AsObservable.ObserveOnMainThread(MainThreadDispatchType.Update)
         // 使用lambda表达式是没有问题的
         .Subscribe(s => TestCrossThreadComm(s))
         .AddTo(this);

     void TestCrossThreadComm(string msg)
     {
         Debug.Log(Thread.CurrentThread.ManagedThreadId);
         Debug.Log(msg);
         transform.RotateAround(transform.position, Vector3.up, 5f);
     }

• 输出结果:

　　1

    　　UnityEngine.Debug:Log(Object)

    　　fire not in main thread

　　UnityEngine.Debug:Log(Object)

 

• 多个参数情况:

 // 定义Signal
 public class TestCrossThreadCommEvent : Signal<string, string, TestCrossThreadCommEvent> { }

 // Install Signals
 Container.DeclareSignal<TestCrossThreadCommEvent>();

 // 启动线程
 tth = new Thread(() =>
 {
     while (true)
     {
         Thread.Sleep();
         _crossThreadCommEvent.Fire("fire not in main thread", "\t so happy.");
         //_unityEvent.Invoke();
     }
 });
 tth.Start();
 // UniRx-Lambda
 _crossThreadCommEvent.AsObservable.ObserveOnMainThread(MainThreadDispatchType.Update)
     // 使用lambda表达式是没有问题的
     .Subscribe(tuple =>
     {
         Debug.Log(Thread.CurrentThread.ManagedThreadId);
         Debug.Log(tuple.Item1 + tuple.Item2);
         transform.RotateAround(transform.position, Vector3.up, 5f);
     })
     .AddTo(this);

• 输出结果:

1

UnityEngine.Debug:Log(Object)

fire not in main thread     so happy.

UnityEngine.Debug:Log(Object)

 

以上为Asset Store中Zenject早期版本.

目前有版本对Signal部分改动如下:

 ...
 #if UNITY_EDITOR && ZEN_PROFILING_ENABLED
             using (ProfileBlock.Start("Signal '{0}'", this.GetType().Name))
 #endif
             {
                 var wasHandled = Manager.Trigger(SignalId, new object[]);

                 wasHandled |= (_listeners.Count > );

                 // Iterate over _tempListeners in case the
                 // listener removes themselves in the callback
                 // (we use _tempListeners to avoid memory allocs)
                 _tempListeners.Clear();

                 for (int i = ; i < _listeners.Count; i++)
                 {
                     _tempListeners.Add(_listeners[i]);
                 }

                 for (int i = ; i < _tempListeners.Count; i++)
                 {
                     var listener = _tempListeners[i];

 #if UNITY_EDITOR && ZEN_PROFILING_ENABLED
                     using (ProfileBlock.Start(listener.ToDebugString()))
 #endif
                     {
                         listener();
                     }
                 }

 #if ZEN_SIGNALS_ADD_UNIRX
                 wasHandled |= _observable.HasObservers;
 #if UNITY_EDITOR && ZEN_PROFILING_ENABLED
                 using (ProfileBlock.Start("UniRx Stream"))
 #endif
                 {
                     _observable.OnNext(Unit.Default);
                 }
 #endif
 ...

涉及到ProfileBlock的使用ZEN_PROFILING_ENABLED来开启， 所以想用Signal跨线程通信，否决掉ZEN_PROFILING_ENABLED就可以了.
