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(1000);
            _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(1000);
        _crossThreadCommEvent.Fire("fire not in main thread", "	 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[0]);

                wasHandled |= (_listeners.Count > 0);

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

                for (int i = 0; i < _listeners.Count; i++)
                {
                    _tempListeners.Add(_listeners[i]);
                }

                for (int i = 0; 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.
