Emitters aren´t replicated?

[Evil-Devil]

Hi there,
i have an GameObjective which spawns an emitter into the world were it was placed in the UED. BUt why didn´t i see my Emitter in a MP GAme. Aren´t they replicated?

 

[Mychaeel]

class Emitter extends Actor
    native
    placeable;

[...]

defaultproperties
{
    [b]RemoteRole=ROLE_None[/b]
    Style=STY_Particle
    DrawType=DT_Particle
    Texture=S_Emitter
    bNoDelete=true
    bUnlit=true
}

Obviously not.

A simple solution to this problem is that you either make your GameObjective always relevant or spawn an invisible actor that is always relevant and make it spawn effects.

 

[Evil-Devil]

The GameObjective is allready bAlwaysRelevant=true And it spawns the emitter.
Might it be enough to set the properties of my emitter which i spawn in my GameObjective class to another remoterole?

Or any other ideas?
I just need an touchable gameobjective, best would be a static mesh. But all the code i´ve found yet in UT2K3 the statics were imported as lightwave mesh. And don´t know if it is possible to use meshes i´ve created in UED to assign to my gameobjective. So it would be for example like an xDomPoint

Either configure your emitter to be replicated (i.e. set its RemoteRole to something else than ROLE_None) or make sure you spawn the Emitter client-side as well, e.g. from a simulated function.

This is what I have on one of my classes that spawn effects on-line

RemoteRole=ROLE_SimulatedProxy
bAlwaysRelevant=true

StaticMesh as Gameobjectiv?

I've an Objective wich must be Destroyed, in it I have this code:

class GoalSpecial extends DestroyableObjective
	placeable;


var GRGoalObject dummy;

replication
{
	reliable if (Role == ROLE_Authority)
		dummy;
}


simulated function PostBeginPlay()
{
	Super.PostBeginPlay();

    if (Level.NetMode != NM_Client)
    {
        	dummy = Spawn(class'GRGoalSpecial',self,,Location-PrePivot,Rotation);

        dummy.Goal = self;
		ResetAll();
    }
}

simulated function ResetAll ()
{
	bDisabled = False;
	dummy.SoundPitch = 64;
	dummy.Reset();
}


DefaultProperties
{
     DefenderTeamIndex=1
     DestructionMessage="Terrorists destroyed the bomb"
}

GRGoalSpecial:

class GRGoalSpecial extends Decoration
	abstract;

var GRGoal Goal;

replication
{
	reliable if (Role == ROLE_Authority)
		Goal;
}
simulated singular function Touch (Actor Other)
{
	//....
} 

function TakeDamage (int Damage, Pawn instigatedBy, Vector hitlocation, Vector momentum, class<DamageType> damageType)
{
	Goal.TakeDamage( Damage, InstigatedBy, HitLocation, Momentum, DamageType );
}

Hmm. I had thought that my initial reply was sufficient for Evil-Devil to find the cause of his problem and to fix it. I even added a highlight...

 

[Evil-Devil]

Michaeel, i´ve read your post seriously, but no one is perfect Cause there was a native in the declation, i mentioned i can´t be switched to another remote role.

Thanx to all answers yet, i´ll look forward to use one of them.

 

[Wormbo]

"Native" only means there's some code for this thing (class, function, whatever) in DLL files. That's all.

Instead of changing the emitter's remote role, wouldn't it make sense to just spawn it on every client?

 

[Mychaeel]

If you have the proper notification on every client anyway, sure.

On the other hand, if you have to communicate the event that spawns the emitter separately to every client first, that'd somewhat defeat the purpose of spawning it client-side in the first place, so you could just as well just spawn it server-side and leave it up to the engine to send it to all clients. That might even be more efficient than devising an UnrealScript-level mechanism to specifically communicate that event to all clients.

 

[Zarkazm]

Of course. I was kinda assuming the game objective spawns the emitter when it's created and then the emitter remains permanently active. I fear I don't feel comfortable with replication yet. I have read the theory, but I think only with practical experiments will I get the hang of it.
What I wonder about is how much sense it makes to try moving effects and other not globally relevant (whatever I mean with that) elements to the client to reduce server load.

 

[Evil-Devil]

yea, it works fine. I´ve added a simulated to my funtions and the Emitters are shown in a network game.
Thx guys

Adding a simulated in front a function doesn't gurantee network compatiability. It's just in this case it did.

 

[Mychaeel]

It's just in this case it did.

I do think Evil-Devil didn't try to say any more than that.

 

[Evil-Devil]

Whats wrong with it? It works and thats what it should. Maybe i´ve to change it later, but for the moment it is ok how it works. And thats all what i wanted. See the emitters in a networkgame.

Wasn't meant to be offensive, I just wrote that incase someone searched a thread on this, and decided to put simulated in front of his/her functions and finds that it didn't work and then complains ... that was all really.
