Multicast delegates

Legacy UDK Programming and UnrealScript

When my camera actor gets inside water volume, it should notify several actors (weather effects manager, wind directional source, post process manager etc). Currently, I can reference only one of them. Is there any way to implement multicast?

Camera collider



event PhysicsVolumeChange(PhysicsVolume NewVolume)
{
    If (LZ_Volume_Water(NewVolume) != None && LZ_Volume_Water(NewVolume).VolumePostProcess != None)
    {
        EnteredWaterVolume(NewVolume);
    }
    else
    {
        LeftWaterVolume();
    }
}

delegate EnteredWaterVolume(PhysicsVolume V);
delegate LeftWaterVolume();

Weather effects manager OR Wind directional source (same code)



function InitWeatherEffects()
{
        BaseActor = Legend_Camera(PC.PlayerCamera).DummyActor;
        If (BaseActor != None)
        {
            // Init camera dummy delegates
            BaseActor.EnteredWaterVolume = BaseEnteredWaterVolume;
            BaseActor.LeftWaterVolume = BaseLeftWaterVolume;
        }
}

function BaseEnteredWaterVolume(LZ_Volume_Water V)
{
    bIsInWater = True;
}

function BaseLeftWaterVolume()
{
    bIsInWater = False;
}

do you mean a networking UE4 Multicast? im not sure of what you mean= ?

I need a single delegate to hold multiple references. Something like:


SomeActor.CollisionDelegate = OtherActor1.MyFunction + OtherActor2.MyFunction;

Or:


For(a=0;a<OtherActors.Length;a++)
{
      if (SomeActor.CollisionDelegate == None)
            SomeActor.CollisionDelegate = OtherActors[a].MyFunction;
      else
            SomeActor.CollisionDelegate  = SomeActor.CollisionDelegate + OtherActors[a].MyFunction;
}
