Elevators do not work correctly when SpongeForge is installed on the Server - Also rarely occurs without sponge.

[D3nnis3n]

I just tested this too (Sponge was NOT enabled when i got, reported and tested the EcologyMod Desync Bug and the Advanced Rocketry Bug!), and found out your mod does not work right when SpongeForge is installed. It seems to bug around intstead of moving or just moves to the lowest Point it can and get's stuck there. I couldn't extract much out of the spam of Errors in the log. So you might try it oyurself. Afaik most mods should be able to be compatible with it nowadays, even the car mod is :D

[Thutmose]

can you include a paste of the spam of errors?

[D3nnis3n]

I try to do so after i tested the new orespawn Version through.

[D3nnis3n]

The spam does not get logges and is so fast that it is really hard to copy it out of console

[D3nnis3n]

Okay, the spam was not related to Sponge. But yeh, the issue persists and NO Messages are logged at all. It behaves nearly ecactly like the Advanced Rocketry issue. The Elevator will jsut get stuck - but you won't wall through the Floor. And it does work correct occasionally. I make you another Video.

Ok, and this only occurs when sponge is installed?

[D3nnis3n]

Yes. If i remove sponge everything works fine for at least the two minutes i tested driving up, down and all around.

[D3nnis3n]

Also since the last Version if i reskin the Controller it is visible immediatly and not only after reconnect - thanks for that fix that somehow got in oO

[Thutmose]

In your sponge settings, try disabling all of the entity related settings and see if that does anything.

I did find why the reskin wasn't synced immediately and fixed that.

[D3nnis3n]

Like that?

entity {
    # Number of colliding entities in one spot before logging a warning. Set to 0 to disable
    collision-warn-size=0
    # Number of entities in one dimension before logging a warning. Set to 0 to disable
    count-warn-size=0
    # Number of ticks before a painting is respawned on clients when their art is changed
    entity-painting-respawn-delay=0
    # Number of ticks before the fake player entry of a human is removed from the tab list (range of 0 to 100 ticks).
    human-player-list-remove-delay=0
    # Controls the time in ticks for when an item despawns.
    item-despawn-rate=0
    # The upper bounded range where living entities farther from a player will likely despawn
    living-hard-despawn-range=0
    # The amount of seconds before a living entity between the soft and hard despawn ranges from a player to be considered for despawning
    living-soft-despawn-minimum-life=0
    # The lower bounded range where living entities near a player may potentially despawn
    living-soft-despawn-range=0
    # Max size of an entity's bounding box before removing it. Set to 0 to disable
    max-bounding-box-size=0
    # Square of the max speed of an entity before removing it. Set to 0 to disable
    max-speed=0

Nope, did not help. Also, may just be random. But i only found this Happening on the highest Floor. It did not yet occur on any other Floors. And as you can see it starts working again after some time. Maybe that helps somehow.

[Thutmose]

Ya those, also check for other optimizations that might be affecting entity updates, it maybe datamanager things?

[D3nnis3n]

I'll do so. I also linked your issue to one on their github. Maybe they can help. I hope so.

[Thutmose]

sponge is somehow making it desync:

I told it to go down, and the top light turned off, and a few seconds later the bottom light turned on, so the server has it down at the bottom, the client has not been notified of this yet.

Relogging results in this:

So somehow the elevator's position or movement isn't being synced to the client. This should be synced via a combination of vanilla entity syncing, as well as some datamanager values used by the elevator itself (for coordinating which floor is being gone to for the elevator's button lighting, which does also seem to be a bit buggy when the elevator glitches on the client like that, you can see it by looking at the colours of the buttons on the elevator, it still thinks the elevator is trying to move on the client, when they server says it is at destination, on relog the buttons have correct lighting)

[Thutmose]

The reason why collision is working fine, is that on SMP, the player's movement wrt collision is almost entirely handled on the client itself, this is why flyhacks work, so the player is colliding off the client side version of the elevator, so they walk on it just fine. The earlier bug where you would fall through it was an error in the collision code itself related to AR's gravity stuff and the elevator not properly accounting for some cases where its velocity was set.

[D3nnis3n]

Thanks for your great explanations, very interesting. As i linked the issue over there i just hope they'll see them, or would you like to post them there, as this seems like something being altered by sponge?

[Thutmose]

I will try to look into it some more on my end before I take it to them, as I would like to try to narrow down what seem to be breaking first.

[D3nnis3n]

Alright, over at sponge it was suggested to look if it is in spawn protection or a plugin is activated that interferes and cancels Events. I got None of both.

[Thutmose]

It seems this issue isn't specific to sponge, I had it occur once on my testing server, so it can occur without sponge, just very rarely

[D3nnis3n]

I could not yet reproduce it without sponge. There at least is a coincidence it happens way more often with sponge, then.

[Thutmose]

It has only happened once so far on my non-sponge server, over a few hundred uses of the elevator...

[phit]

I wasn't able to reproduce this with Sponge 1.12.2-2529-7.0.0-BETA-2732 and thuttech-6.0.7

[Thutmose]

Hmm, has anything entity sync related changed in sponge lately? I had this bug happen once without sponge, out of a whole lot of elevator use, so it isn't specific to sponge, most likely a vanilla or forge sync issue that was somehow worse with sponge

[phit]

Nah, nothing was changed to my knowledge. OP may have had some weird config options enabled that are recommend to be disabled with mods, like tile entity activation ranges. Without knowing their global.conf, Sponge versions etc. this is pretty much impossible to debug.

[D3nnis3n]

I had the latest Version of sponge to that date. I update all my mods every day. Config in respect to tile Things can be seen above. Dunno which Information is missing. Did not Report this issue to sponge, but instead here and Thut was able to reproduce himself, so ... yeh. If you Need something from me, just ask me.

[phit]

your sponge global.conf, specifically you wanna disable entity activation range for thuttech

Here you go.

[phit]

yeah, no idea your settings seem fine, try setting the values to 0 instead of just enabled=false maybe that setting is borked

[D3nnis3n]

That didn't work out. After several tries the same issue occurs rarely again. Funny bug.
