Monster Client Desync

[fr blood]

Hi guys I open this thread to talk about bugs that happens only on a server, and not in single player. For the ones who know I'm working on After Doom, and the gameplay itself if fine in single player without any problem that I can't fix, even when I open my own server, if I connect on it I don't meet new bug(maybe because I'm the host).

The problem comes when I open a server with BE to test it online with some friends, and here it's a disaster a tons of bug happens and I really don't know how the hell I can fix them since they come only online.

An example is with the zombies, when they hunt you, or try to dodge you, in single player it's fine, but online they teleport so I can't kill them easily.

Same with the weapons, in single player they are nicely balanced(in my view) and make their job, but online I kill an enemy with the double amount of ammo(and not because their hp is raised).

I don't know if I have to share some code here maybe that you guys could find the problem.

By the way I've noticed that we can use Zdoom ACC on Zandronum, but here too it works fine only in single player.
Online a lot of funtions just don't start, for example "GetWeapon", in my mode this function is called when the player do an action like launching a grenade because it's launched from another weapon selected with the script and after that it's suppose to give back the old weapon that the player had before. It seems to work, but again online when I see the weapon I'm suppose to have my friends tell me that I'm using a pistol(what I don't see in my own screen), and here too I can't fix it because I don't know where the problem is from.

Thanks for your help.

Yes, because otherwise we honestly have no clue what you're talking about based on your vague description of the situation.

By the way I've noticed that we can use Zdoom ACC with slade and it works fine with Zandronum, but here too it works fine only in single player.

Sounds like you either need to update ACC.exe or ZCommon.ACS. Open Slade's settings and make sure it's pointing to the latest ACC directory. Honestly I don't even use Slade for ACS, i write it all out in a notepad and use a homemade .BAT batch file to compile it.

As I said the problem is when they walk around online, sometimes it's fine and sometimes they teleport by that I mean that their sprite it still at the same position when the actor itself is somewhere else, and when he enters in his fire state the teleport end.

[Ænima]

That sounds like client desync. I noticed you use a lot of jump states and checks in the actor's DECORATE. Could that be it? Maybe a script is checking for desyncronized information.

[fr blood]

I didn't have the choice with the jump states, if I didn't use it the zombies would just be invisible online, that solution was found by Zombo.

I wanted to thank him but my comment was sent to trash with the [necro] witch I don't know what it means.

[Ænima]

Yeah something in those jumps is getting desync'd. Could it be your user variables?

Also maybe i'm not aware of something but

Code: Select all

        "####" E 0 A_JumpIfTargetInLos(2)
        "####" E -1 A_Jump(256,"See")
        Goto See

is that necessary when you can just have this?

Code: Select all

        "####" E 0 A_JumpIfTargetInLos(1)
        Goto See

Or does that cause things to be invisible? Based on Torr's explanation of the sync perils of client/server jump prediction, I'm assuming that's what you're trying to circumvent, although I've used similar code in the past using inheritance and never had any problems. I also jump using state names instead of number offsets nowadays, although I'm not sure if that has anything to do with it.

Yeah that cause things to become invisible.
I'm gonna try this:

Code: Select all

"####" E -1 A_JumpIfTargetInLos("AnotherState")
Goto See

Hoping it will fix the problem.

It didn't worked, I really can't tell from where the problem is, could the devs check this when they'll have the time ?

[ibm5155]

on a case where you have just one or two monsters on the server, the problem happens too?

I don't know I didn't checked if it happens depending on monsters number, but it looks like that I've found a way to reduce this problem, I've replaced the old state by that:

Code: Select all

"####" E -1 A_Jump(256,"AnotherState")
Wait

It makes sure that the actor do nothing until he hasn't changed his state on both clientside and serverside, it could maybe be THE SOLUTION.

-1.
I never get why there's a need of -1 over decorate
0 for me it'll run in zero tics.
1 will delay 1 tic ( I think it's in tics...)
-1, hmmm, I'm coming back in time?

-1 means forever.

Look at that:

Code: Select all

Missile:
POSS E 10 A_FaceTarget
POSS F 8 A_PosAttack
POSS E 8
Goto See

That the code we finfd in the original zombieman when he attacks, for now there is no problem offline and online.

So now if I want to make a new monster based on the zombieman and that I would like it to conserve his original attack, then I would have this:

Code: Select all

ACTOR NewZombieMan : ZombieMan
{
  States
  {
  Spawn:
    POSS AB 10 A_Look
    Loop
  See:
    POSS AABBCCDD 4 A_Chase
    Loop
  Pain:
    POSS G 3
    POSS G 3 A_Pain
    Goto See
  Death:
    POSS H 5
    POSS I 5 A_Scream
    POSS J 5 A_NoBlocking
    POSS K 5
    POSS L -1
    Stop
  XDeath:
    POSS M 5
    POSS N 5 A_XScream
    POSS O 5 A_NoBlocking
    POSS PQRST 5
    POSS U -1
    Stop
  Raise:
    POSS K 5
    POSS JIH 5
    Goto See
  }
}

As always offline it will work fine, but it's here where start the problem online, if the missile state(or any state) is used from another monster, then the monster who used this state will become invisible online.

So the only way that I found to fix that bug was to edit the original ZombieMan itself with that:

Code: Select all

Missile:
POSS E 10 A_FaceTarget
POSS F 8 A_PosAttack
POSS E 8
POSS E 0 A_Jump(256,"See")
Goto See

The jump will make sure that new zombie man go back to his "See" state online, so he won't become invisible anymore.
But even here we got another problem the client desync, they will start to teleport(on clientside) making them very hard to kill.
And I guess that is because of the short delay "0" that they have to make the jump.

After searching on the forum I found Zombo's solution:

Code: Select all

Missile:
POSS E 10 A_FaceTarget
POSS F 8 A_PosAttack
POSS E 8
POSS E -1 A_Jump(256,"See")
Wait

And actually it's the best proper way to avoid both bugs and desync that I found, "-1" means that the delay is infinite until the monster make the jump state, and wait will force the monster to go back to this line until he makes the jump.

If you guys have encounter this problem when making a project with new monsters and found a solution then your help is the welcome.

I think there's a problem related to inheritance of actors, or maybe a possible misuse on your end. I encountered some inheritance problems while I was trying to make a base actor with special death states all added, but none of them actually worked and the actor just went invisible as soon as it happened. Might be worth a report on the bugtracker as it sounds awfully similar.

[Ænima]

Have you tried using Goto Super::See?

I just tested it, and it didn't solve the problem.

Don't rely on states in the original actor if you modify the see\spawn and pain states only. You'll end with unpredictable execution sequences in the code. Copy paste the original zombieman missile to that newzombieman and see if it'll work better (almost sure it will).

I think the movement desync online is because you used A_Recoil and ThrustThing. They'll appear to teleport all over the place online (Somehow calling a_stop after them makes it less visible online).

Edit : Your fix is more of a walk around than a real fix. All you did was tell it to go specifically to the "see" state. Instead of it being goto super::see when you use the old missile state because of inheritance :P.

I don't remember good results when using "####" as the sprite in zandronum.

As you can see my zombies are very complex that why I use inheritance, if I didn't then it would take a tons of codage, but I'll do as you said for these states.

I will make a test by removing all A_Recoil/ThrustThing movement it could maybe solve the problem.

You are right it's not a fix at all the problem is still present, if only I was able to predict exactly when it comes then I could fix it by myself but sometimes the zombies work fine and other times start jittering.

I don't remember good results when using "####" as the sprite in zandronum.

So it confirme that I'll have to wait for the next Zandronum updates ?
I'm going to make more test using this special sprite and if the problem happens again I'll open a ticket about it.
