Interaction not showing online.

[Angel_Mapper]

I'm using an Interaction to show some information on the player's HUD, and it works perfectly offline, but doesn't show at all online. I looked at the log and testing it online I'm getting an Accessed None in the ModifyPlayer function, but the error doesn't appear offline. Here's the function, from my mutator class:



function ModifyPlayer(Pawn Other)
{
local Player P;
local int i;
local bool bHUDIsSetup;

if (PlayerController(Other.Owner) == None)
return;
if (PlayerController(Other.Owner).Player == None)
return;

P = PlayerController(Other.Owner).Player;
for (i = 0; i < P.LocalInteractions.Length; i++)
{
if (P.LocalInteractions[i].IsA('SwitcherInteraction'))
bHUDIsSetup = True;
}

if (!bHUDIsSetup)
P.InteractionMaster.AddInteraction("AngelWeaponSwitcher.SwitcherInteraction", P);

Super.ModifyPlayer(Other);

return;
}


Any help? :bulb:

... err, ignore that post if you saw it, I bothered to go look.

However, in any case, with errors like this I strongly suggest you do some logging to find out the specific cause of the accessed none. Just go through logging all of the var values until you see what's coming up as none.

Err... could you look specifically at what errors you get? Some simple counting can sometimes show you what's giving you errors (keep in mind you'll get two for one line if it gives you an 'attempted to assign a variable through none' error.)

I'm guessing Other.Owner or (Other.Owner).Player

I'm still kind of half-awake but it looks to me like you want that code to be executing on the client-side. I think Player is client-side only.

[Angel_Mapper]

Yeah, I only need the interaction to be added client side, nothing to do with the server.

[Angel_Mapper]

Narrowed it down to this line, I'm guessing there are no LocalInteractions server-side.


for (i = 0; i < P.LocalInteractions.Length; i++)

Any idea how to get all this to take place client-side only?

Class Interaction isn't derived from Actor, hence it won't replicate by itself anywhere. Your Interaction must be created on each client separately.

See Unreal Wiki: Creating an Interaction from a Mutator (http://www.unrealwiki.com/wiki/Creating_An Interaction_From_A_Mutator) for details.

Aargh, it's still not working. I set it up exactly how the Wiki has it and still no dice.



simulated function Tick(float DeltaTime)
{
local PlayerController PC;

if(Role==ROLE_Authority && Level.Game!=None && Level.Game.bGameEnded)
{
SetTimer(1.0, False);
}

if(bHudIsSetup)
return;

PC = Level.GetLocalPlayerController();

if (PC != None)
{
log("Bueller? Bueller? Bueller? Bueller?");
PC.Player.InteractionMaster.AddInteraction("AngelWeaponSwitcher.SwitcherInteraction", PC.Player);
bHUDIsSetup = true;
}
}

defaultproperties
{
bAlwaysRelevant=True
RemoteRole=ROLE_SimulatedProxy
}


I'm not even getting the "Bueller" line logged on the server or the client.

[legacy-Mychaeel]

That's in a Mutator subclass, right?

If so, did you add your code package to the server's ServerPackages? (See Unreal Wiki: Debugging Techniques (http://www.unrealwiki.com/wiki/Debugging_Techniques#0.2)).

omfg, I feel so incredibly stupid. lol

Just need to replicate some variables and it's good to go, thanks a bunch! :haha:
