mod_development

[terse mason]

Very valid. Lotta new stuff and things to find

[fathom forum]

can you help me understand some of the things in this function?

[terse mason]

Sure. Which parts? I'm not an expert so I can't promise I can answer fully but I will try

[fathom forum]

what is playerObj meant to be?

it looks like they are adding items and perk levels to some player

perhaps for debug

[terse mason]

It seems to be the Player Character that interacts with it, specifically the IsoPlayer object
https://projectzomboid.com/modding/zombie/characters/IsoPlayer.html

I can't tell you why it's setting the Level to 7 though. My guess is Debug or a custom dev scenario that spawns in and uses all of these functions

Looking at the names of the other functions in the file

[fathom forum]

thank you for the resource
it doesnt have any description of what it is tho

ya its probably for testing

[terse mason]

https://projectzomboid.com/modding/index.html

https://demiurgequantified.github.io/ProjectZomboidLuaDocs/index.html

These 2 are good for searching for official functions

[fathom forum]

thank you

[terse mason]

Otherwise, I just load the entire Project Zomboid folder into VSCode and search lol

[fathom forum]

thats a good idea

[terse mason]

Helps to have an IDE search for you instead of suffering through it manually lmao

[fathom forum]

one of my goals is to have a radio broadcast that i can send text to through the normal text chat box

/radio hello

kinda thing

hi spiffo

[terse mason]

tagged by spiffo

Like, have a radio and use it to transmit to chat, or just command based?

[fathom forum]

like i want my players to tune into a station
and i can make the radio say stuff

[terse mason]

Mmm I see I see

[fathom forum]

for example as admin i would type
/radio hello

and their radio would have hello text

hello again spiffo

later on i would like it to trigger based on their actions but one step at a time

[terse mason]

Fair

I don't think that would be too difficult, at least the command part. Not sure about Radio part

[fathom forum]

media\lua\server\radio\ISDynamicRadio.lua

may hold the answer

[stable hearth]

Well that was a silly little project but it's done.
I've now got a mod that prints out every distribution list into a CSV file that can be imported into Sheets/Excel to aid in better balancing loot drop rates. Still gotta do the math and all that (which I have a Google Sheets for)...

[terse mason]

ISWeatherChannel.lua

--Definition of bc pulled from WeatherChannel.FillBroadcast
local bc = RadioBroadCast.new("GEN-"..tostring(ZombRand(100000,999999)),-1,-1);

function WeatherChannel.AddFuzz(_c, _bc, _chance)
    local rand = ZombRand(1,_chance or 12);

    if rand==1 or rand==2 then
        _bc:AddRadioLine( RadioLine.new("<bzzt>", _c.r, _c.g, _c.b) );
    elseif rand==3 or rand==4 then
        _bc:AddRadioLine( RadioLine.new("<fzzt>", _c.r, _c.g, _c.b) );
    elseif rand==5 or rand==6 then
        _bc:AddRadioLine( RadioLine.new("<wzzt>", _c.r, _c.g, _c.b) );
    end
end

[terse mason]

That's insane but cool. Screenshot?

[stable hearth]

I can show you the output in my excel sheet. XD

[terse mason]

Ofc lmao

[stable hearth]

https://docs.google.com/spreadsheets/d/1En9xdCZScF4eff0Z6QU_GF3H5-udQmilPHM-LvRabCE/edit?usp=sharing

[terse mason]

Oh wow, looks pretty

[stable hearth]

I wanted a tool to be able to logically balance all the outputs from all the damned mods... But there was no way to see the results AFTER the mods patched the distribution lists... So... I made one.\

[terse mason]

Not sure if you know, but does Reloading the Lua pull in the Distribution List again if it's been changed?

[stable hearth]

Every time you restart the server, if you have enabled set to true on SandboxVars, it'll redo it.

So... Yesn't?

There's also an insane number of options for output

    Enabled = true,
    PurgeExistingLists = false,
    Rules = "distlist.all",

    -- Valid rule patterns (examples)
    -- distlist.all
    --   -> Writes 3 CSVs: procedural, distributions, suburbs
    --
    -- distlist.<group>
    --   -> Writes 1 CSV for that group: procedural | distributions | suburbs
    --
    -- distlist.<group>.<prefixOrExact>
    --   -> Writes 1 CSV for a subtree/prefix (e.g. procedural.Wardrobe)
    --      or an exact list/path (e.g. procedural.Wardrobe.ClassyMan)
    --
    -- distlist.all.comprehensive
    --   -> 3 group CSVs + top-level subtree CSVs (Wardrobe-level granularity)
    --
    -- distlist.all.totalcomprehensive
    --   -> EVERYTHING: group CSVs + subtree CSVs + each exact list/path CSV (lots of files)
    --
    -- Multiple rules: separate with ';' or newlines
    --   e.g. "distlist.all;distlist.procedural.Wardrobe"
}```

So purge just clears the folder it's outputting to.
Rules determine which distribution lists it outputs.

Probably going to see if I can do the same thing with the vehicle spawn lists as well.

[terse mason]

Also, for this

RadioLine.new("<bzzt>", _c.r, _c.g, _c.b)

parameter1 = Message to Display
parameter2 = Red value (RGB)
parameter3 = Green value (RGB)
parameter4 = Blue value (RGB)

[stable hearth]

(Note: This was all very much vibe-coded.. I cannot take credit for it outside of conception and end execution)

[terse mason]

Fair. Not exactly a mod concept that gets me jumpin out of bed

but very interesting anyways

[stable hearth]

I mean, critical if you want to ensure loot spawns are balanced.

Became obvious this was necessary after looking at how many mods just mad spam their loot.

[terse mason]

My heart wants to make an tool for modifying this stuff more easily and to make it more accessible, so I'm very curious. My brain may not want to, but my heart

[wet sandal]

Dev tools are awesome! Do it!

[stable hearth]

Oh yeah, I feel you. Being able to edit that in a gui would be nice, but probably hell to accomplish and then output effectively.

[sonic needle]

ClipSize = #,

isnt this that?

[small topaz]

Is there a way to convert a CharacterTrait object to the corresponding CharacterTraitDefinition object?

[terse mason]

https://tenor.com/view/toasted-im-steaming-cooking-fail-gif-12957577

Mmm... Gui app...

[wet sandal]

@small topaz

The highlighted one is a Map<CharacterTrait, CharacterTraitDefinition>
Assuming its exposed to lua that should do it

[small topaz]

What is the syntax for using such a java map in lua? Can I just use
local traitDef = characterTraitDefinitions[MyRegsitry.MyTrait]
?

[wet sandal]

I think it should be something like this
local traitDef = CharacterTraitDefinition.characterTraitDefinitions:get(MyRegsitry.MyTrait)

Because the map is a java object, you gotta use the get method

[small topaz]

ok thanks! I'll try that.

[flint beacon]

My local mods on my mod folder are not working with this latest update do I need to restructure the folder?

[wet sandal]

Moving from 41?

If so yes

[flint beacon]

No from 42 to 42.13

They just won’t work anymore like custom clothing

[wet sandal]

Ah, no folder structure changes im aware of

[flint beacon]

Weird

[wet sandal]

@flint beacon
I think there was a similar issue with clothing mods above:
#mod_development message

Not sure if the resolution he posted helps you

[small topaz]

aren't they showing up in your in-game mod menu?

[flint beacon]

They show up on the mod menu but won’t appear on character, was just wondering if I needed to change anything

[flint beacon]

Ty I’ll check this out

[small topaz]

They changed a lot of things in their Lua-Java-API. For example, the whole bodyLocation system is different now and your clothing mod will pbbly not work anymore if you don't adjust. Also, they changed a small thing about how to define your item's script.txt file. So you might have a look at this as well.

[flint beacon]

That must be it then

Thanks much appreciated 🙂

[dull moss]

#musicmaniacpins loot distribution dump with modded changes

[stable hearth]

Hmmm? Yeah, that's what that is.

[dull moss]

Yeah I know, I pinned it for myself

[tranquil reef]

Does Umbrella have an easy way to see what an old function has changed to

I have the 42.13 version installed but it doesn't give an error for outdated functions, just doesn't give an error when I put in the new 42.13 version

[pastel whale]

super random question is there a hotkey to hotswap to your inventory's respirator? if not there a mod for it? ..... and if double not, could be a sexy af mod that lets you hotkey swap headgear to respirator and back.... lmao i dunno shit about LUA but maybe id be curious

does feel like a kinda obvious vanilla hotkey though... i just slayed a nice batch of airborne infected zombies with riot gear so they couldnt scratch me, now that theyre nice and proper re-dead i would probably want to quickly whip out at least a N95 so their rotting corpse gasses dont infect me after i axed them all down

[fathom forum]

when i try to connect to my server with a non admin client it says the lua file does not match the one on the server

do i need to put my mod folder in the steam install folders workshop folder too?

[cyan tusk]

Is there a mod that can record some activities in a log, activities such as activating god mode, activating invisible, spawning items? for b41

[bright fog]

Read the MP notice guide in the pinned messages

[bright fog]

No. @bronze yoke has copies of old decompiles if I'm not mistaken but not of the Lua

[low solstice]

I love how OnPlayerUpdate and getStats for Boredom will just give you values don't match the actual changes

[peak furnace]

so weird question, i figured i'd ask here
i'm thinking of "cleaning" my save a bit by deleting some files, but i'm not really sure how they're laid out. i assume there's some way to correlate this data to a grid

what i'd like to do is create a gui for this. might end up picking up python to create a little script that lays it out. but i also don't know how the cells are structured

[verbal yew]

fellas, is there any reason to put your files in folders other than scripts/
like scripts/generated etc?

[bright fog]

The generated folder are simply generated scripts by TIS automatically

[verbal yew]

I just don't understand the difference, in my opinion, everyone just throws their script files into the script folder, without any subfolders...

Like, is that OK?

https://tenor.com/view/heavy-heavy-tf2-heavy-team-fortress-2-heavy-team-fortress-two-thinking-gif-13167291159341927470

[bright fog]

If you make subfolders, there won't be any clash with other files named the same way

It's a question of organizing your mod files

[verbal yew]

thanks, king

[bronze yoke]

(in b41) the real boredom level is in BodyDamage

for some reason stats had an entirely separate boredom level that is tracked and increased/decreased by certain things but does absolutely nothing

in 42.13 the stat revamp moved all stats back to stats and cleared up all the weird stuff like that

[low solstice]

well yes but the difference between each OnPlayerUpdate does not match the increases/decreases it is behaving fairly weird.

[tepid skiff]

Does anyone know why, if I export an animation in Blender (even with no edits), my weapon and backpack bug like this please?

[nimble badger]

It seems the backpack and weapon prop bone got mixed up in your animation, if you enter debug mode and press 6 it should let you know what animnode the game is currently using, which might be the cause of this issue..

[cunning kestrel]

Do we know how "player:getMoodles():getMoodleLevel(MoodleType.Endurance)" changed in 42.13 ?? it stopped funtioning.

[nimble badger]

Pretty sure it was explained here https://github.com/SirDoggyJvla/Archive.Project-Zomboid-Modding/tree/main/TIS guides/B42 unstable MP

[grizzled fable]

are recipeGroup usable at this stage? i tried to use it but maybe i'm missing something 🙁

[cunning kestrel]

ive seen the guide but not sure i understand it xD

[nimble badger]

Pretty sure they changed the name of many moodles... Not sure if player:getMoodles() still works tho

[quasi holly]

Hey can I just edit the main textures in the main folder for a custom skins and clothes

I did b4 42.13

Will it brake every thing if I don't make a mod..new to this. Just been editing mods with paint love it

[bronze yoke]

the moodletype members have changed names https://demiurgequantified.github.io/ProjectZomboidJavaDocs/zombie/scripting/objects/MoodleType.html

[brittle swift]

So after getting my mod to properly load onto a dedicated server, this is what's coming up in the console logs on the server whenever trying to actually craft any of the custom recipes

[bright fog]

Oh hey that's me

[bright fog]

What the hell are recipe groups ?

[nimble badger]

I think it was that weird thing they talked about... Being able to join multiple craftings into a same group eg: Craft long implement

[shy mantle]

Did they replace getEndurance with getLastEndurance ?

[bright fog]

Maybe ?

Check the Java docs

[grizzled fable]

craftRecipe OpenBoxOfJars { timedAction = UnPackBox, time = 15, OnCreate = RecipeCodeOnCreate.unpackItemTypeFromBox, Tags = InHandCraft;Packing;CanBeDoneInDark, category = Packing, recipeGroup = OpenBox, inputs { item 1 [Base.BoxOfJars] flags[AllowFavorite;InheritFavorite], } outputs { item 6 Base.EmptyJar, item 6 Base.JarLid, } }

from C:\Program Files (x86)\Steam\steamapps\common\ProjectZomboid\media\scripts\generated\recipes
make a grouped expandable list of item with the same use
check in the crafting window ingame at packing you will see a group of OpenBox stuff

[brittle swift]

Yeah, it seems to be essentially a flag used to merge multiple recipes into one from the user's perspective in game

[shy mantle]

It was changed, that explains why it's not working then lol

[bright fog]

That's mappers

[shy mantle]

I just pushed it aside as a later problem

[bronze yoke]

so now we have meta recipes and recipe groups 😅

[grizzled fable]

not that

[brittle swift]

Has anyone had any luck getting custom recipes to work on dedicated servers? I seem to be hitting a wall on what looks like a check for whether the recipe can be performed while walking (which it can't) but that's assuming I'm interpreting the console output correctly and I'm honestly out of my depth at this point. 😖

[bright fog]

It needs to not be in a custom module

It needs to be in the Base module

[brittle swift]

Oh it does? I guess I misunderstood how the modules worked & thought all of our custom content had to be inside of custom modules.

[bronze yoke]

it is good practice to do so, but it is not working as of the latest patch

[brittle swift]

Even the testmod they gave us in the sample documentation had their custom recipes in a custom module so I didn't think that had changed

[bronze yoke]

it will probably be hotfixed soon

[shy mantle]

The difference between getEndurance and getLastEndurance is Last needs to be done on the server side for multiplayer now :P

I should have known because I need to set the endurance by removal on the server as well now lol

I don't like all this syncing stuff

[bright fog]

Overall your mod should run server side now

Any stat changes should be done server side and a sync call should be sent, no need for commands, there should be functions to do that

[brittle swift]

That resolved it and my mod is working now. Thank you so much!

[bright fog]

np

[brittle swift]

So.... it appears my mod works now but is also causing completely unintended consequences on dedicated servers. No errors are coming up in either the client or server console but other functions are definitely broken when the mod is in play, specifically the ability to turn on a generator. Any suggestions on trying to tackle that?

And for context, the mod is nothing more than a few custom items and some custom recipes. Nothing else.

[tranquil reef]

Do items with Hidden = true appear always in debug mode

[bright fog]

Appear where ?

[bright fog]

Recipes need to be in the module Base

Due to a bug

[tranquil reef]

In the inventory

Wasn't sure if that was an intentional thing or if I just didn't do it right

[bright fog]

I think it shouldn't appear at all in the player inventory ?

[tranquil reef]

I use "Hidden = true;" exactly. Does true need to be capitalized or something

ah, I'm a dumbass

";" lol

[bright fog]

Yea why tf do you have that lol

[small topaz]

So the vanilla ISBuildAction is still in the client folder? How is this supposed to work in multiplayer?

[bright fog]

Idk, there's some timed actions that are still client sided somehow

[small topaz]

Some TimedAction may not need any server side stuff. So they are fine in client folder. However, ISBuildAction is for actually building stuff like walls which you and other players are supposed to interact with in the game world. Therefore I wonder....

[bright fog]

The transfer items timed action too I believe ?

[brittle swift]

Yeah, I moved all of them to the Base module which is what got them working. I just now have a weird bug that after performing any of the recipes I can't turn a generator back on until after I disconnect/reconnect it.

[small topaz]

Yes, ISInventoryTransferAction is also in client which is weird since it manipulates player inventory...

[bronze yoke]

that action has always been super weird so i'm not questioning it

[arctic kayak]

Hello guys! Does someone know if TIS have planned to remove those very low limits to capacity for vehicle trunks? Nothing can go above 50 for backpacks and 130 for vehicles... That sounds absurd to me that a 40 tons semi-truck have the same capacity as a shopping cart... 😅

[heavy stone]

Too easy to live out of a car if you can carry an entire stockroom in a hatchback. Just get a mod.

[arctic kayak]

Do you know something called "Kenworth W900 Semi-Truck"? It's like a giant truck. It's trailer is bigger than my house, but its carrying capacity is equal to my garbage bin in B42. AND it allready comes from a mod. I don't ask you to judge me, i ask if someone know if TIS will remove those stupid limits they implemented in B42 so that players can enjoy a realistic game like in 41.78.

[bright fog]

There is a framework to go over this limit if you want

https://pzwiki.net/wiki/JB_Max_Capacity_Override

But to answer your question, I haven't heard of them saying they'll remove it tho I haven't heard the inverse either

[arctic kayak]

Cool! Thank you!

[bright fog]

I think the reason they did that was for security reasons

Anti-cheat reasons to be more specific ?

I mean that'd be a logical reason to do that at least 😅

[arctic kayak]

But they made a game moddable... If they don't want people to make content, that make no sens to me. 😅

[bright fog]

You're assuming they did it to hurt modders, but they didn't

[arctic kayak]

I'd like to believe you, but I really don't understand those arbitrary limitations that came out of nowhere... For me it's like saying "you enjoyed those mods? Well we don't allow you to enjoy anymore, you have to suffer."

[queen oasis]

I do wish they'd open up caps on SP

[arctic kayak]

Well, thank you anyway for the framwork, maybe i'll try to locally modify Ki5 vehicle mods if he/she doesn't implement it^^

[mellow frigate]

in B42.13, I want to do something on a client once an item from its inventory was modified server side (its mod data is modified and syncItemModData is called). Is there already some callback I can attached my client on, to get it ?

[true nova]

why not just make some more item containers to pair with the vehicle?

[bright fog]

Bcs that doesn't make any sense

You have a massive ass truck and it's split into a hundred containers ?

Plus good luck managing that shit lmao

[true nova]

make it look like one

wouldnt work for one very heavy item

[bright fog]

It's not that easy

It also doesn't remove the limitation technically, you just now have 50 containers lmao

I wouldn't call that a solution at least 😭

[queen oasis]

looking at ItemContainer.getCapacity, that math.min is sus as hell. idk what the compiled is but I'm betting it's fixed in the next update

[true nova]

or just dont put the item in the container and store it in a table and count all the weight yourself 🤔

[queen oasis]

I thought about that for player inventory but then my head fell off

[arctic kayak]

I had this idea when i tried to bypass the 50 cpacity for backpacks

Never managed to make it work even with AI helping me

[drifting ore]

*especially with AI ‘helping’ you

They don’t know hardly anything about Zomboid and end up doing more harm than help

[arctic kayak]

Yeah. It s*** a little bit. But it saved me years for syntax

[drifting ore]

Helping with the basics is fine as long as you understand what your code is. I can’t imagine trying to maintain a mod that I don’t know what it does, and I’ve seen plenty of examples of people who will try AI code just because they don’t know how to write their own

Then they come into a support channel and paste some code that doesn’t make a lick of sense and everybody points and laughs

I learned a lot by trying it own my own and writing terrible code that everyone pointed and laughed at anyways, but you get the idea

[arctic kayak]

Yeah, i get it. But in fact I mostly use AI to understand how code works. When i don't understand how a mod is functioning, i give function to it and i ask to explain me what the role of each line

[bright fog]

Terrible idea 😅
Because for items to be saved by the game, they need to be in an ItemContainer

So at the end of the day, you still need to manage to put your item in the container

[nimble badger]

Pretty sure there were some issues when many individual items were inside a player bag or an inventory container...

[true nova]

oh yeah i have mods that i need things to save like that. i store its data in moddata and instance it again

is a lot of moddata though

if it was all containers

[bright fog]

Take care with that, it can easily do suppositions of what the game does when something is named in a way, and yet it doesn't do what it thinks the code actually does

[drifting ore]

Yeah I was going to say that could easily turn dangerous

[bright fog]

Same, that's also a terrible idea because how do you store uniques ? You store every single data ? Do you store the mod data of items in another mod data ?

There's too much limitations to rely on such a system, too many problems that can appear from this

This solution needs to be the LAST solution

But like I mean, the LAST OF THE LAST, actual LAST

You should absolutely not do that if there's a few dozen potential solutions that would be better

For example in the horse mod we needed to have a container that was accessible from the horse

[true nova]

yea the things i was doing that with are specific items and are all vanilla that have limited data

[bright fog]

A solution could be the mod data thing, and there'd be likely other solutions, but we went with moving an invisible container at the feet of the horse instead, bcs the more we use the default game systems, the best it'll work

[arctic kayak]

Yeah, Copilot made A TON of halucinations. I had to copy-paste the same prompt with the code every 10 min so it can remember what i was asking about... 😅
But as i said, it saved me years. I managed to fix some mods despite my only experience in coding was a bit of c++ and html like... 25 years ago... (edit: well 21, actually, i'm not as old as i imagined)

[true nova]

so 50 containers as one is best solution 🤔

[arctic kayak]

It may cause problem since they implemented very unsecured right-click otpions when it comes to inventory containers when they implemented their "rename" option

[true nova]

actually. why not just change the weight of the items being placed in there?

then change them back when removed

what is the samllest weight an item can have? could do near infinite items if its really small

[arctic kayak]

To be realistic, it would have to scalled dynamically with the size of the container...

[true nova]

obviously i was just curious at how fast i could break the game

[arctic kayak]

I haver tried some things while i was trying to fix ProximityInventory

Like creating an invisible backpack that agregate all containers around the player and showing it all at once

But the thing is that the UI seems to dynamically "create" the type of the container when you right-click on it

[small topaz]

Does the SandboxVars.MyMod.Something variable contains the correct sandbox setting even when playing a non-sandbox game (apocalypse,survivor,...)?

(which should then be just the default value for that game mode ofc)

[arctic kayak]

I think you need a fallback in case there's no sandbox options, but i'm a big noob

[small topaz]

good point! not sure if you need it everywhere but using it is a good idea...

[arctic kayak]

With my poor logic, I would certainly test something like "if SandboxVars.MyMod.Something ~= nil then"

[winter bolt]

it uses the default value you set in the sandbox script file

the gamemodes are sandbox presets so any modded sandbox options that arent listed in them will just be default

[bright fog]

Yea

[sly gazelle]

I'm trying to update this old mod to 42.13 for personal use. Got a ton of errors when i just booted the game with it.

seems like they removed `TraitFactory´ table

so how to register traits in this new version?

[bronze yoke]

https://pzwiki.net/wiki/Creating_a_trait_mod

[sly gazelle]

thanks

[gloomy ember]

anyone know where i could modify the starter kit?

[hybrid tiger]

I might be tweaking, but I was looking through, and cant seem to find the lua code file for
RecipeCodeOnCreate and RecipeCodeOnTest
I am trying look at some examples within the vanilla games and cant find that file anywhere.
I remember having it pulled up before, did they move it with the update?

Ah nvm I see what happened, I didnt do enough digging they got moved to Java it seems

[gloomy ember]

nevermind i found it, its in ProjectZomboid/media/lua/shared/items/SpawnItems.lua

you can change it in function SpawnItems.OnNewGame

[hybrid tiger]

To continue off this, is there a link or something I can read more about this and still look at them / implementing?

[small topaz]

In lua, when I have a CharacterTrait objec like CharacterTrait.ARTISAN or from my own registry, is it possible to print this very object name as a string? So that it outputs the string "CharacterTrait.ARTISAN" ?

[hybrid tiger]

Found SimKDT's videos going to watch and that should hopefully answer my questions, will ask if I need help later

In 42.13, some worn backpacks return nil when using item:getBodyLocation() on them?? Is this new?

just tested it via print-to-console:

EDIT: So ok... When  your clothing item is also a container, you can get its bodyLocation now only by `item:canBeEquipped()`, not anymore by `item:getBodyLocation()`... good.... 😐
EDIT2: ok... not always... some may stil work with getBodyLocaiton, some don't... pbbly somewhat buggy from the game's side here

In B42, should I put the mods I create into the Zomboid\mods folder? When I open the mods section in the game, the mods I put in the mods folder don't show up.

[small topaz]

B42 requires a new folder structure for mods, different from the one in B41

[bleak grotto]

Where can I learn this?

[small topaz]

https://pzwiki.net/wiki/Mod_structure

[bleak grotto]

I didn't understand. Which folder should I put the mod I want to develop into?

[small topaz]

you can still use the Zomboid/mods folder but you have to make a new folder structure within your mod as described on the wiki page I linked

[bleak grotto]

Zomboid/mods/SimpleTestMod/
mod.info
poster.png
Contents/
mods/
SimpleTestMod/
common/
lua/
client/
server/
media/

I'm doing it this way and it's not working.

[bright fog]

Mod info in wrong place

Go back reading the mod structure page

[magic nexus]

Hey everyone,
I’m doing some reverse-engineering on Project Zomboid vehicle mods and I noticed that most mod FBX files seem to be authored/exported at 0.010 scale in Blender.

Is there a specific reason for using 0.010 as the base scale?

[bright fog]

You mean in the script ?

[bleak grotto]

I noticed it and put the mod.info in the correct place. However, I still can't see it in the mods section of the game. Could you please provide the correct file structure?

[magic nexus]

No, I mean in Blender itself, not in the vehicle script.

The FBX files are already authored at 0.010 scale inside Blender, before any in-game script scaling is applied.

That’s what I’m trying to understand the reason for.

[bright fog]

You need to follow the wiki

https://pzwiki.net/wiki/Mod_structure

[bleak grotto]

The mod appears when placed in the Workshop folder, but it doesn't appear when placed in the Zomboid\mods folder.

If I don't specifically create a file for version 42.13, it doesn't show up in the workshop. I understand correctly, right?

[bright fog]

No it does anyway

Your mod.info file was just in the wrong place in.what you showed us

[rich reef]

Hello everyone,

I have been fiddling around with some drainable items and trying to use setUsedDelta() to adjust them, and it seems to work, but when I exit the area, or log out/log back in, the item does not seem to retain the change.

Or if it does retain the change, it is off slightly from what it should be. Say an item with 500 uses, with a useDelta of 0.002, should be at 500 when it is at max value, which is what it shows in game, but when I return its at 498 instead.

I've tried rounding and truncating the value from getUsedDelta() to have minimal decimal points and slop in the numbers, and then adding my increase to that with setUsedDelta(), but when I immediately grab the value again afterwards and print the result there is added decimal value completely irrelevant to what numbers I provided/calculated from, almost like a rounding error.

Sometimes when I come back to an area, teleporting to/from, the item with half usage is reset to full value, or another odd value that doesn't correspond to anything I had set.

Does anybody know why this happens, or a workaround? Been trying to figure it out, but it doesn't have much rhyme or reason behind what its doing.

This is my code, as of now, to try to test this. Basically just re-filling a Charcoal Bag with some handfuls of charcoal, a few at a time, and in-game it seems to work at face value, but does not hold it's value when I leave/return in various manners.

function OnCreate_AddHandfulOfCharcoal(sources, result, player, item)    
        
    for i = 0, sources:size()-1 do
        local item = sources:get(i)
        
        if item:getType() == "BagOfCharcoal" then
            local currentUseDelta = item:getUsedDelta()            
            local adjUseDelta = math.floor(currentUseDelta * 10 + 0.5) / 10            
            local truncUseDelta = tonumber(string.format("%.3f", adjUseDelta))            
            item:setUsedDelta(truncUseDelta + 0.1)
        end
    end    
end

Thank you for your assistance!

Map=Muldraugh, <----

[heady shoal]

Muldraugh, KY is always already written in the config files, so i assumed it was right, in b41 u had to write it like that 100% idk if it changed in b42

[heady shoal]

should i try without KY?

[sonic needle]

i would look around for evidence to check, im unsure myself

[magic nexus]

When I try to open the vehicle editor, I only get a grey screen instead of the editor UI.

Has anyone run into this issue before?

[heady shoal]

it has to be there right? if i delete it from that line the whole map will deissapear?

[heady shoal]

okay

[heady shoal]

YOOOO, okay now i deleted muldraugh, ky and all maps worked but the original map, that means it was overriding them, maybe i should put muldraugh ky the last one?

[sonic needle]

any advice i give at this point is 100% likely to be wrong, as its not somethin
g ive done

[heady shoal]

no but thanks to you i found out they can work indeed, now i have to find how to do it propertly!! THANKs

[rich reef]

When loading maps onto a server, Muldraugh has to be last, otherwise modded maps won't load.

[heady shoal]

GODDAM okay hahah thanks

[bright fog]

No I believe that is normal yea 😅

[sonic needle]

that tripped me up Instantly xD

[heady shoal]

if i copy players db to the new save files, will all players from server keep levels and everything? ty

[mellow frigate]

Hello, I do not know drainables enough to give you answers, I do not even know if getUsedDelta represents the missing uses or the contained uses or whatever. At your place, I would print the evolution of getUsedDelta & getEntityNetID before and after any change to better understand what comes from logic / from math / from game save&load shenanigans.

[verbal yew]

FELLAS! Please teach me how to work with interfaces, I really want to create my own little window((

currently tinkering with propane refill from those little lantern bottles, but i'm not sure where i'd find RecipeCodeOnCreate.refillBlowTorch

aha. found it. but it's all garbage i can't read lol, uhhh. shit

[verbal yew]

can u send it?

[peak furnace]

looks something like this

Use this to decompile the java to be readable https://pzwiki.net/wiki/Zomboid_Decompiler

[peak furnace]

oh, thank you

[verbal yew]

srysli... all function OnCreate for recipe a javaside now?!

https://tenor.com/view/wtf-what-the-fuck-the-fuck-is-this-wth-gif-17571836

[peak furnace]

well they are function calls

[verbal yew]

I used to often change what some of these things do after crafting, but now I’m not sure I'll be able to.
After all, this thing was used back in the day to predetermine the result.
It’s good if I can modify my own recipes using Lua, but how to intervene in the vanilla code now...
Looks like I’ll have to learn Java...

[peak furnace]

whatever you do, i wouldn't recommend using a chatbot to make your code

notoriously unreliable, will often cause more problems than just doing it yourself
but it can be useful in places. just make sure you fully understand the code it's implementing and don't just copypaste

[verbal yew]

That’s not something I do
reverse engineering at most.

[peak furnace]

very good

[peak furnace]

the utility appears to be having trouble finding ProjectZomboid.jar

which, uh, doesn't exist. in my files. for some reason
that's odd

[thin swan]

Do you want to decompile for b42.12 or b42.13?

[peak furnace]

ohhh, that's probably my mistake, i'm decompiling .12

i'll backdate

[thin swan]

Ah yeah you need the version before the latest one

[peak furnace]

got it, cheers

Hey is there a mod where my character could lose weight faster?

[winter bolt]

new function for moving bodylocations

[wet sandal]

Should I be concerned with the bodyLocation list order for any reason?

I'm working on Equipment UI right now, but I haven't gotten to custom bodyLocations or anything yet.
Just been using the predefined constant bodyLocations so far.

[winter bolt]

no its just the order the clothing is rendered in

[wet sandal]

Oh. Oooooooooh.

That actually is of interest to me.
I define the preferred top item for combined slots based on the order I write my own lists in. This sounds like a much more reliable way to do that.

Well, maybe. Worth trying out at least.

[smoky vine]

hey sry if its obvious to you guys but where do i go to fix the names of my backpacks? It says it uses module.itemID for the name, so i thought it would be kuromi_backpack?

[grizzled fable]

yes those are the recipecodes XD

[verbal yew]

love your mod, my fav into 41, btw :з

[frank elbow]

I haven't been paying much attention to the recipe side of things, so someone correct me if I'm wrong: pretty sure the move of those to Java means Recipe is no longer a defined table

So it's odd that that was working before, given that

Which update was it working in?

[grizzled fable]

just before this one i suppose, anyway i just need OnCreate to work, how to use that now?

i just remove Recipe.?

maybe this class is no more?

[frank elbow]

Assuming the referencing works similarly to how it did in b41, which I imagine it does, it just has to be anything accessible in the global environment

So, your own global table with recipe callbacks, a global function, whatever

[verbal yew]

https://pzwiki.net/wiki/OnCreate_(craftRecipe)

[grizzled fable]

this is old i think, it's how is done now

[frank elbow]

Huh, it does still have Recipe. there 🤔 Could've sworn I saw people talking about how that was gone

It does say 42.5.1, but I figured it was an earlier change

[verbal yew]

i mean, its should be like:
craftRecipe MakeBiofuel
{
timedAction = MixingBucket,
time = 500,
tags = AnySurfaceCraft,Campfire,
skillRequired = Farming:1,
category = Herbalist,
OnCreate = Recipe.OnCreate.GetBottle,
inputs
{
item 1 [Base.Pot;Base.Bucket;Base.BucketForged;Base.PaintbucketEmpty] flags[IsEmpty] mode:keep,
item 1 [Base.Fertilizer;Base.CompostBag],
item 1 [Base.BakingSoda],
item 1 [Base.OilVegetable],
item 1 [Base.PetrolCan] flags[IsEmpty] mode:destroy,
item 1 tags[Fork;MixingUtensil;Spoon] mode:keep flags[MayDegradeLight],
}
outputs
{
item 1 Base.PetrolCan,
}
}

wheres OnCreate = Recipe.OnCreate.GetBottle,
just OnCreate = YourFuncGetBottle

and just simple function YourFuncGetBottle(craftRecipeData, character)

without Recipe. like tables etc

[bronze yoke]

i'm pretty sure it was removed in 42.13 since that's the only time i've heard people complain about it

it may have just been left in until now for compatibility or something, i don't think it was used

[grizzled fable]

ok ty

[verbal yew]

yep, method work
#mod_development message

in Recipe OnCreate = zReMyTestFunc,
In lua server side
(just this is code without notging more)
function zReMyTestFunc(CraftRecipeData, character)
print("My Test Func Work")
end

[grizzled fable]

yep gotcha ty 😉

[noble yoke]

OnCreate =
I think this part doesn't work anymore. document said most of the OnCreate function was moved to java part. if you add OnCreate to your mod it might cause some error on server side.

[frank elbow]

I see, that makes sense

[bronze yoke]

no, this is basic modding api, it works fine

the vanilla oncreates were replaced with java implementations for type safety reasons, no other changes were made

[noble yoke]

this is my previous attempt when I was using this mod on my server and got this log while crafting got adrupted by server. my guess is it's due to OnCreate stuff in that mod. once I remove it and its lua part it works fine.

[earnest mulch]

Hello,

I am a novice modder, and I am having trouble getting my mod to work in MP [42.13.X].

In short, my mod only adds items, recipes, and translations in Lua. The items work, but when I try to create the recipes, they only progress 1% and then stop without creating or using anything.

Do I have to do something specific to make them work in MP, like something in Lua or something like that?

[mortal wraith]

Im trying to make more variants of the Kitty Keychain to add one that looks like my cat, and i got the icon textures and all that working, but the placed world item uses its giant 2d texture instead of the 3d one. Ive tried copying the KeyChain_Kitty.fbx world model but my added Keychain_Kitty5 does not use it. am I missing a script or something?

[verbal yew]

your recipe should be in Base module
but items shouldnt
if your mods items in Base module - your new recipes not working

If anything, it's just bypassing the error, according to the idea, everything should work without such dances (with its own modules or in base ones), just the problem is the latest version.

[earnest mulch]

Thanks, I'll test that out.

[verbal yew]

u should scripting your 3d model

[mortal wraith]

So since i was just adding a variant of an existing model, in the added item's script I had "model KeyChain_kitty" and i thought it'd use the same model, but I had to use "model Keychain_Kitty5" and make a variant for it

solved tho

[open drum]

hi guys, has anyone already asked how to make spawning inventory items in MP changed in new update? build 42?

i've read the PDF file they uploaded

and used the "sendadditemtocontainer() " function

the item goes into inventory correctly

but they are not usable

nor can't be dropped onto the ground

do i have to use SendClientCommand() function or something?

[winter bolt]

are you spawning the item in the client or server?

[open drum]

client

[winter bolt]

spawning it in client wont work anymore so everything related to that has to be done on the server

[open drum]

the code runs in client folder .lua

bit confused on that

[winter bolt]

what does your mod need to do?

[open drum]

i have this UI

that when clicked on the item icon

spawn item

[winter bolt]

oh yeah in that case you need to make a clientcommand

[open drum]

hold on let me show u the code

local function onConfirmPurchase(item)
-- Get the main window and the stored item
    local item = what_item[1]

    print("this is item 1  " ,item.item:getType())

        if CheckInventory() >= item.price then
        getPlayer():Say("your price was  "..item.price)

        if instanceItem("Base."..item.item:getType()) then
            local itemadded = getPlayer():getInventory():AddItems("Base." .. item.item:getType(),1);
            sendAddItemToContainer(getPlayer():getInventory(), instanceItem("Base."..item.item:getType()));
            for i = 0, item.price-1 do
            local credit = instanceItem(SandboxVars.Wuro.Credit)
                local removeditem = getPlayer():getInventory():RemoveOneOf(SandboxVars.Wuro.Credit)
                sendRemoveItemFromContainer(getPlayer():getInventory(), credit);
            end
        else
            local itemadded = getPlayer():getInventory():AddItems("WURO_items." .. item.item:getType(),1);
            sendAddItemToContainer(getPlayer():getInventory(), instanceItem("Base."..item.item:getType()));
            for i = 0, item.price-1 do
                local credit = instanceItem(SandboxVars.Wuro.Credit)
                local removeditem = getPlayer():getInventory():RemoveOneOf(SandboxVars.Wuro.Credit)
                sendRemoveItemFromContainer(getPlayer():getInventory(), credit);
            end
        end
    else
        getPlayer():Say("You have not enough credit(s)")
    end

end```

[open drum]

so... use the Event.OnClientCommand.Add() ?

[bright fog]

Send a call to the server to spawn the item server side, and sync that to the client with the proper commands

[winter bolt]

you need to make a lua file in the lua/server folder that will have a function that does all of that item inventory stuff so that you can call SendClientCommand to tell the server to execute the function

1 sec im gonna make an example script

[open drum]

i see i see

[earnest mulch]

Thanks again, I was able to fix it. I had to change the modules of items and recipes to Base, and now it works perfectly in MP.

[winter bolt]

the args in sendClientCommand is a table that you send to the function on the server but i dont know if items can be values

local Commands = {}
function Commands.CheckMoney(player, args)
    -- do all the item creation and inventory management here
end

local function OnClientCommand(module, command, player, args)
    if module == "YOURMODIDHERE" and Commands[command] then
        print(command)
        Commands[command](player, args)
    end
end
Events.OnClientCommand.Add(OnClientCommand)

-- this is how you call CheckMoney 
sendClientCommand(getPlayer(), "YOURMODIDHERE", "CheckMoney", { item = itemHere })

[open drum]

so this must go into server folder

right?

[winter bolt]

yeah

make a new folder inside server with your mod name or something and then name it something like ClientCommands.lua

[open drum]

then the code of

item creation go inside the server folder?

or can it be stayed in client ?

as long as the creation start in server?

[winter bolt]

it goes in the CheckMoney function in the clientcommands script

[open drum]

hmm i see

[winter bolt]

in the client you do sendClientCommand(getPlayer(), "YOURMODIDHERE", "CheckMoney", { item = itemHere })

[open drum]

local candle = instanceItem("Base.Candle")
self.character:getInventory():AddItem(candle);
sendAddItemToContainer(self.character:getInventory(), candle);

[winter bolt]

to tell the server to run the item code on its own end

[open drum]

so for example

that code snip

[winter bolt]

yeah that code should be in server

[open drum]

i see i see

[winter bolt]

sendAddItemToContainer syncs the item to the client

[open drum]

gotcha

so i don't need to use the sync command separately like the pdf says

self.generator:setActivated(self.activate)
self.generator:sync()```

[winter bolt]

thats for world objects i think

[winter bolt]

this is all you need for items

[open drum]

this is only for the object (tiles) in the map

gotcha

ill try it

thank you spongie

that was great help. clearing things out

[winter bolt]

i think all of this would be moved to server and then replace it in the client code with sendclientcommand

[open drum]

yea looks like it

gotta do lots of rework in the code XD

[winter bolt]

and then anything you need to pass from the client to the server you can add to the table at the end of sendclientcommand

when its inline its kind of confusing but you can do it like this as well

and then the server function can just do args.item to access it

[open drum]

hmm goodo idea

[finite scroll]

my professions, while they work perfectly in singleplayer, do not appear in multiplayer. is there a common known cause for this?

[frosty cypress]

I was working on a mod and i was trying to go into the lua debugger to find what went wrong and i couldn't find the script for the mod anywhere, and i was asking to see if anyone knew why. I knew someone had a similar issue but it was 2 years ago and the solution was never posted. this is using build 42.

[bronze yoke]

that probably means your file isn't loading in the first place

[small topaz]

I also have a profession mod which I updated for 42.13. Works fine in single player.

I just checked it in mp and have the same problem as you. Doesn't work for me in mp. New Professions are not shown in the UI.

[frosty cypress]

thanks, i'll try to look into it on my own to see if i can find the issue before asking again.

[small topaz]

Ah! I solved it! All I need to do is to add a server folder to my mod's lua folder! Maybe you should try it!

[finite scroll]

interesting, that’s strange

i’ll give it a shot

i do remember someone mentioned their mods unless they added the client folder, so i could see this happening

[small topaz]

Maybe you need a server and possibly a client folder for the game to somehow recognize the mod for mp? Don't know. But just adding an empty server folder did it for me. Btw I also have a (non-empty) client folder. So better you give your mod a client folder too, even if it is empty.

[finite scroll]

i also do already have a non-empty client folder

[wintry tree]

I wonder what that folder does? I don't have server folders in mine but they show up in MP.

Is there someway to disallow clothing items added by default for a specific occupation?

[finite scroll]

unfortunately, mine still do not seem to appear

[small topaz]

wait... I'll test again to be 100% sure...

[finite scroll]

it's possible i have other underlying issues because i've been struggling to get other mods that should work to run

[half pelican]

Hello! I'm trying to get this code to work in B42MP (on a dedicated server).
Using debug messages, I see that swf.FatigueVar and swf.EnduranceVar are changing correctly, but after waking up, they return to their initial values.
Apparently, there's something I don't understand about player:getStats():set(CharacterStat.
Do I miss something? I would appreciate any help.

[wintry tree]

I guess I could recreate the clothingselectiondefinitions file but that's a long work around.

[small topaz]

I just tested again. Works for me. I am on 42.13.1 and use the "host" button to test mp.

[finite scroll]

same here

[wintry tree]

of course that would screw default clothing for every other modding profession...crap

[finite scroll]

what operating system are you using? i wouldn't expect it to make such a large difference but i've experienced linux-specific issues in the past

so it's not out of the question

[small topaz]

I also have a mod doing this and I used exactly this method: deleting them form the ClothingSelectionDefinitions. Not so much work though. You just have to iterate this nested table which can be a little hairy at the first but is really not much coding.

[wintry tree]

Are you guys adding them locally? Not from the workshop?

[wintry tree]

Oh, is it like a matter of doing table.remove or something?

[small topaz]

I am on Linux too, Mint! Altogether, mutliplayer isn't great for me since my game sometimes crashs or "loose contact to server" when I try to host. But it still works sometimes which is enough for first tests and loading and starting mods works fine.

Are you sure you enabled the mod correctly? When in the MP mod menu, you select then mod, and then press "next" to go to the mp sandbox menu and then press "save"? It is necessary to it this way cause otherwise the mod is not enabled.

[small topaz]

I test locally from my Zomboids/mod folder.

[finite scroll]

I think I did but I'll do some sanity checks

[wintry tree]

Oh, don't mind me then lol. Maybe that file is the key then. Mine were already on the workshop. I updated them for 42.13. Then downloaded them from the workshop to test in MP so the set up is different.

Is there anything useful for you here? https://pzwiki.net/wiki/Mod_structure#Common_and_versioning_folders

[small topaz]

Yes, using table.remove appropriately. Iterating the table and doing it this way allows you to really only delete items you want and not overwriting the whole table. If you overwrite, any other mod modifying this table will be incompatible with yours.

[wintry tree]

Sounds good. I will do that.

Thanksk

I have another question. I suppose I could test this but if you know off the top of your head...How can I remove a trait from a mod without interfering with ongoing saved games. Would removing it's registry entry be sufficient?

[small topaz]

when you search through the table, make sure to test whethe each field exists before you use the delete command. For example, when you would like to delete some specific pants item,

    -- delete stuff from myTable["Female"]["default"]["Pants"]
end```
pseudo code but I guess you know what I mean 😉

[wintry tree]

Imma just test it real quick

Test Complete: ...No

[finite scroll]

yep i did exactly that, still doesn't work

i'll do more testing later

[wintry tree]

So, I'm not sure if I can remove a trait from my mod without screwing on going saves

[silk sigil]

Movespeed delta can't be touched by Lua anymore in 42????

[small topaz]

Not sure if simply deleting the registry is safe for save game although I guess so cause otherwise, it would pbbly be impossible for player's to remove a trait mod from an existing game.

oh wait Iam confused XD

you tested removing clothing or traits now?

XD

[wintry tree]

I just tried and the game won't launch. Before 42.13 just commenting the trait out worked. It was still available in game but couldn't be selected in trait selects.

I tested remove traits

Oh wait. I think I might know

IsProfessionTrait = true, in the scripts file

removes from trait select but remains in saved game where it was selected

[small topaz]

yeah. this makes the trait not selectable in the trait selection menu anymore. good trick!

to remove it from an existing game on a player, try player:getCharacterTraits():remove(yourTrait)

[wintry tree]

Oh, I don't want to remove it from the player. I think that would make people mad. I have a traits mod and I dont' really like it anymore. Some traits should be occupations but I didn't know how to do occupations at the time

So, I'm trying to give it a makeover without breaking peoples games

[small topaz]

then using the IsProfessionTrait = true trick seems to be a good idea!

In multiplayer B42, can we still use the ModData.get("myUniqueKey") to permanently store data on the server?

Also in B42 multiplayer, is there some kind of unique player ID which is always assigend to the same player even when logging out and logging in again? (Guess there is such a thing but I am wondering how to access it...)

EDIT: ModData.get() doesn't seem to work for me. It has some functionality but data seem to get lost when server is shut down (i.e. leave game as host playing via "host" button). Not sure if my testing is though...

[rich reef]

Thanks for the response,
I did debug prints with my original code, to verify the changes to the code.

The original getUsedDelta() is associated with the remaining value of the item. It would show something like 0.900000000346, for example.

I would then round/truncate a copy of that value to 0.900 before adding delta of 0.002 , to hopefully remove any decimal errors and keep it clean.

This was also verified with another print, showing 0.902, 0.904, etc, as I added additional value to the variable I used to then set the setUsedDelta() of the item.

But upon immediately retrieving the value from the item with getUsedDelta(), it would again show odd decimal issues, such as 0.904000000362, or similar.

This didn't seem to affect how it worked in game, as it would show the value in the item editor, and the remaining uses seemed to be correct as well.

But the weird issue, is upon leaving the area, either through running far, fast traveling, or teleporting, and then coming back into the area, the item would not maintain the set value of useDelta at all. It would either reset to the full amount, be an arbitrary amount far higher/lower than set before, or if the item was set to full amount before leaving the area, it would have a missing remained, for instance 498/500 instead of 500/500 as it should have been.

I am not sure what's causing that weird anomaly, or if I am missing some code that needs to be run to sync the changes with the server, or if it's an error in my code. As far as I can tell, things seem to be similar to others who have mods/items that adjust the useDelta of an item.

Any ideas? Been throwing things at the wall and not much is sticking on this one. I'm sure someone has had an issue like this spring up before.

[wintry tree]

Does anyone have an example of how to do trait swap in 42.13?

Something like - if player:HasTrait("Graceful2") then
player:getTraits():remove("Graceful2");
player:getTraits():add("Graceful");

But don't know how to do on character intialization

[small topaz]

if player:hasTrait(traitPair.swap) then                                                                                
      playerTraits:remove(traitPair.swap)
      playerTraits:add(traitPair.with)
 end```
This works me for in single player 42.13 and 42.13.1. Put this code in the client folder and add it to the OnNewGame event. Won't work on multiplayer though.

Oh... and it may not work for all traits. For example, for me it does behave strange for the outofshape trait (but that was already an issue back in B41).

EDIT: corrected code! (forgot to say what "playerTraits" is)

[wintry tree]

I'm going to try Events.OnCreatePlayer to see if that'll work

[small topaz]

anyone know what sendObjectModData(IsoObject o) from the GameServer does?

[winter bolt]

you can do it on the server with OnCreateLivingCharacter if you check to make sure the character is an IsoPlayer but ive not been able to figure out a way to check if the player is new since that event fires whenever you load a save as well

player:getSurvivedHours() == 0 didnt work when i tried that

[small topaz]

couldn't you try to send a command from the client to server when client triggers OnNewGame event, catch the event on server and then do the trait swap on server? this would ensure that the player is indeed new

[winter bolt]

yeah thats the easiest way

i had to do that in my mod

[wintry tree]

I had it working in 42 previously but the code was given to me.

[small topaz]

Must say that I never tried but I just thought that this would work in theory...

[wintry tree]

It was something like this - NewProfession = {}

NewProfession.DoNewCharacterInitializations = function(playernum, character)

local player = getSpecificPlayer(playernum);
local inventory = player:getInventory();

if player:HasTrait("Brave2") then
    player:getTraits():remove("Brave2");
    player:getTraits():add("Brave");
end

end

Events.OnCreatePlayer.Add(NewProfession.DoNewCharacterInitializations);

Don't know if it'll work in 42.13 though

[small topaz]

I think if you check whether the player has the trait, then this might also be safe cause when player loads the game, the trait is already gone and nothing wrong could happen

ah, in 42.13 you have to use player:getCharacterTraits(). and hasTrait() with lower case "h" now!

again, see here: #mod_development message

[wintry tree]

Okay, thanks. I think I understand. Not really a coder lol, I'll try it

[small topaz]

ah... also: you have to use those new trait identifiers! just using strings like "Brave2" won't work anymore! read the migration guide here: https://theindiestone.com/forums/index.php?/topic/88499-modding-migration-guide-4213

[wintry tree]

Thanks, I'll look at them.

[small topaz]

Is there a known limitation with the communication via sendClientCommand and similar commands on Linux or is this supposed to work?

[bronze yoke]

this is supposed to work

[small topaz]

Having issues with it and I am on Linux Mint. So here is a minimal example. Maybe some people here see what I am doing wrong:

my code in client folder:

    sendClientCommand(player, "rasBodyMod", "myKey", {})
    print("TEST_OUTPUT_CLIENT onNewGame ")
end
Events.OnNewGame.Add(mainInitFunction)```

my code in server folder:
```local function onTest(mod, command, player, args)

    print("TEST_OUTPUT_SERVER1") 
    print("mod ", mod)
    print("command ", command)
    if mod == "rasBodyMod" and command == "myKey" then
        print("TEST_OUTPUT_SERVER2")
    end
end
Events.OnClientCommand.Add(onTest)```

In coop-console, the only output with the "TEST_OUTPUT" tag I get is this:
```LOG  : Lua          f:7, t:1766120969859, st:1,904,823> TEST_OUTPUT_SERVER1
LOG  : Lua          f:7, t:1766120969859, st:1,904,823> mod     ISLogSystem
LOG  : Lua          f:7, t:1766120969859, st:1,904,823> command     writeLog
LOG  : Lua          f:7, t:1766120969859, st:1,904,823> TEST_OUTPUT_SERVER1
LOG  : Lua          f:7, t:1766120969859, st:1,904,823> mod     ISLogSystem
LOG  : Lua          f:7, t:1766120969859, st:1,904,823> command     writeLog```
So my data seem to be not transmitted. 

The client code seems to be completed fine though.

Is there a special folder structure I need in my server folder or something?

[bronze yoke]

OnNewGame is too early to send a client command

due to what is likely a bug you cannot send client commands until the second game tick

[small topaz]

Ok many thanks! Good to know (and would have been impossible to find out by myself! XD). Then I'll try again!

[lusty kindle]

Anyone have good free sound effect websites?

[slate umbra]

https://pixabay.com/sound-effects/
heya, i've never made a mod before, but I want to change all the radio and TV texts to a custom message. is this an easy task?

[bright fog]

Yes and no 😅

It's not very technical to achieve but it can be very annoying to do

[slate umbra]

is there a form or something i can go to?

[haughty bridge]

A little annoying that they just removed it

[bright fog]

It's not a problem

Just a different system

And a better one overall

[haughty bridge]

disagree, dynamically being able to control what loads was nice

[lusty kindle]

https://pzwiki.net/wiki/Creating_dynamic_radio_channels
you can try looking here to start

[haughty bridge]

I do like the script system do not get me wrong, but is kinda hard to change, like say if X mod is enabled do not allow trait

I guess you could register traits if mod is active?

[open fossil]

Whereabouts are the flags stored, specifically the hanging US flag and the 3-tile wide US flag?

I can't find them anywhere.

[haughty bridge]

the item? or the tile?

[open fossil]

The item, I found the tile. Honestly sorta lost, I'm brand new to all this and I just wanted to make another.

Figured it'd be easy as copy-pasting a few things and directing it to a different texture?

[haughty bridge]

I just love when translation and images do not work despite me following the exact guide

UIName = UI_trait_addictol:resitant,
UI_trait_resitant = "Resitant",

I call bull

[willow tulip]

Whats the new format for character:getBodyDamage():setWetness(...) ?

[bright fog]

I agree, idk yet if they added tools, just in general the registries systems seems good

[haughty bridge]

oh yeah 100%, registries are way way better

its just managing them is the issue

all I know is they completely scewed translation keys and Texture paths X-X

[bright fog]

Yea we'll have to see how that evolves but you can just access the registry in any lua file

[bright fog]

Did you follow the guide on the wiki ?

[haughty bridge]

I can not even get any translations or images to work 😭

yep to a T

I even tested different things

not one thing worked

[bright fog]

Uh I'd need more context I think

@bronze yoke had you managed to make icons and translation work for traits ?

[haughty bridge]

the translation thing is very much annoying me the most, I could care less about icons

cause sandbox translation works just fine

UI_EN = {
    UI_trait_resitant = "Resitant",
    UI_trait_resitantdesc = "Resitant test",
}

module addictol {
    character_trait_definition addictol:resitant {
        CharacterTrait = addictol:resitant,

        UIName = UI_trait_addictol:resitant,
        UIDescription = UI_addictol:resitantdesc,

        Cost = 4,
        IsProfessionTrait = false,
        DisabledInMultiplayer = false,

        Texture =  media/ui/Traits/trait_addictol:trait_test.png,
    }
}

as soon as I try translation here nothing

desc doesnt contain trait cause I wanted to see if one would translate over the other

Unless I am misunderstanding something

and this made following the wiki to

and i mean images are in the irght place

Addictol\42.13\media\ui\Traits\trait_test.png

[bright fog]

I mean your mistake is a bit obvious I feel like

Your translation should have addictol: if I had to guess

As for the icon you named it trait_test.png but in the script it's trait_addictol:trait_test.png ?

[haughty bridge]

tried that to

unless I made a typo

...

istg

yeah no

[haughty bridge]

as for trait that is straight from the wiki

I tried a normal path

still nothin

module addictol {
    character_trait_definition addictol:resitant {
        CharacterTrait = addictol:resitant,

        UIName = UI_trait_addictol:resitant,
        UIDescription = UI_addictol:resitantdesc,

        Cost = 4,
        IsProfessionTrait = false,
        DisabledInMultiplayer = false,

        Texture =  media/ui/Traits/trait_test.png,
    }
}

like this doesnt work either

UI_EN = {
    UI_trait_addictol_resitant = "Resitant",
    UI_trait_addictol_resitantdesc = "Resitant test",
}

from my testing

it is treating UIName UIDescription as just a plane string, it doesnt seem to point to any translation

[bronze yoke]

the value given to UIName needs to match a key in UI_EN exactly

[haughty bridge]

I tried that

but as soon as you say it, it suddenly works >:(

as for icon idk still

[haughty bridge]

wiki s not very much help X-X

I am gonna test with a diff image and see

yeah nope

they must of changed something

cause I never had this issue before

[tacit plover]

try only having "Texture = trait_test,"

[haughty bridge]

lemme test that,

ON A UNRELATED NOTE, I was like "wait a minute that name is familiar"

[haughty bridge]

also nope

doesnt work

I have been beating my head at this problem for like 5 hours

not matter what I try I can not seem to get icons to load

[tacit plover]

yeah, thats very odd - cause i made a quick custom trait, and it worked for me

[haughty bridge]

hm

I have a idea lemme test it

[tacit plover]

you made a registries.lua file as well right?

[haughty bridge]

ye

its not like it isnt showing up

[haughty bridge]

Addictol\common\media\ui\Traits\trait_drinker.png

unless my path is incorrect (I changed the text to trait_drinker)

unless I need it to be in 42.13's file instead of common

[tacit plover]

hmm, its worth trying

[haughty bridge]

nada

I mean its 64,64

a png

and its not like the case sensitive is weird

[haughty bridge]

maybe its a 43.13 bug?

I verified my file integrity and I am going to try with a different icon and see if that helps

[tacit plover]

im on 42.13.1 and its working for me, so this is very odd

it even works with a 64x64 icon (tho its a bit big)

[haughty bridge]

module addictol {
    character_trait_definition addictol:resitant {
        CharacterTrait = addictol:resitant,
        UIName = UI_trait_addictol_resitant,
        UIDescription = UI_trait_addictol_resitantdesc,
        Cost = 4,
        IsProfessionTrait = false,
        DisabledInMultiplayer = false,
        Texture = media/ui/Traits/trait_resist.png,
    }
}

Zomboid\mods\Addictol\common\media\ui\Traits\trait_resist.png

I tried the media thing again

not even doing Texture = trait_resist, seems to work

[haughty bridge]

https://github.com/thekingofspace/Addictol

I rq made a git of it

maybe you may find something

cause I am frankly stumped

[tacit plover]

gonna take a look, cause it should be working

[haughty bridge]

Istg if its something stupid I overlooked I will lose my mind

I swear working with discords API was easier then zomboid 😭

and I had to reinvent several systems since the language I was using didnt have them

[civic galleon]

Being that damage is now being handled serverside, is it a fair assumption that things like player stats such as fatigue are as well? I'm reading up on sendClientCommand right now just in case.

I am asking because I am updating Sleep With Friends. Up until now, it was purely client-side. When I wake up, my Fatigue resets to where it would in vanilla.

[haughty bridge]

I can confirm actually they are handled serverside!

I was testing getting players drunk killing zombies

and updating intoxication server side also replicated to client

[civic galleon]

ooooooh! That sounds fun!

but am I on the right track? Do we edit through sendClientCommand?

[haughty bridge]

it was hysterical, the worst negative trait I could cook up

[haughty bridge]

nah you can just set stat on server and it seems to replicate over

unless I am misunderstanding

[haughty bridge]

And it was so funny, because the more zombies you killed the harder it would get to kill them

[civic galleon]

the functions I have written fire client-side, now calling player:getStats():set(CharacterStat.FATIGUE, math.max(0, modData.swfFatigue) ) so that it works with b42.13

but now that it works server-side (always should have lol) I need to learn how to change this

[haughty bridge]

wait how are you accessing math

I a little newbie at zomboid modding not lua just zomboid

math wouldnt work for me

[civic galleon]

idk it just ahs always worked for me tbh

[haughty bridge]

do you have to require math?

[civic galleon]

no

[haughty bridge]

cause for me it throws a error when I try to use math.max

[civic galleon]

hmmmmm I am newer to lua, this is the only mod I have made for PZ as well

[haughty bridge]

I may of made a type considering honestly

[civic galleon]

used to JS/TS and Python so its all syntax at the end of the day

[haughty bridge]

LOL

I am diehard luau

[civic galleon]

no switch-case kills me ngl

[haughty bridge]

I mean there kinda are

[civic galleon]

even bash has it

[haughty bridge]

make a aray with key value pairs, value being your function

[civic galleon]

but but but before I lose it. How are we updating player stats now on the server???

[haughty bridge]

then once done table.clear and nil the vallue

[haughty bridge]

just player:getStats():set(CharacterStat.FATIGUE, math.max(0, modData.swfFatigue) ) works

@tacit plover you uncover anything btw?

[civic galleon]

but now I have to keep track of each player individually ugh

[haughty bridge]

You see I am decently well known roblox programmer so I am VERY used to having server have controlling over stats

[civic galleon]

it makes complete sense, but I am lazy and didnt think this mod would have needed to exist still

I thought the devs would have solved the lack of good fatigue handling in MP, but they never did

but I am not here to complain, only to solve the issue.

So perhaps what is my best move here? loop through all players and check if asleep, carry on as usual per player?

sleepticks are not evenly spaced btw, if anyone is wondering. You will get anywhere from 3-5 sleepticks per minutetick

[haughty bridge]

Hmm unsure I’d have to run some tests but perhaps that is your best bet

[civic galleon]

ok im getting excited. I think i was just a bit frazzledd earlier because Im also trying to make my own server management tool purely in bash which i am very new at

thank you very much for the info @haughty bridge

[haughty bridge]

I just need to solve this trait icon issue

[tacit plover]

yeah, im not sure why its not showing

its 1:1 to the ones i did, but it still doesnt show

[haughty bridge]

Did work on your end?

Cause if it’s just me, I don’t care

[tacit plover]

its not working, but now i wanna know the reason

ill keep tweaking it, if i find a fix ill ping ya

[haughty bridge]

Thanks I really hate riding on someone else fixing it

I am out of ideas of what the hell could be wrong

[frank elbow]

Unrelated note that it currently says “resitant” instead of resistant, if that wasn't already noticed

[haughty bridge]

….

Fuck

[frank elbow]

Unfortunately no clue what the issue is at a quick glance though

[frank elbow]

Idt that would cause it because it's consistently misspelled, just pointing that out

[haughty bridge]

I am not known for my spelling LOL

Every single variable I have ever written probably has a typo

And also is some crude term that makes no sense

just ignore the amount of variables that are just 3 letters

For my discord bot wrapper the cached heartbeat value is labeled RST I don’t know why

I just did it that way

[frank elbow]

I have no way to confirm nor deny this, but I imagine that anyone who's done any amount of programming has had the thought “if it works, it works” much more than anyone who hasn't

(that said, clear variable names are a nice habit for future reading lol)

[haughty bridge]

Obviously

For my open source libraries I use clear names

Anything where it’s just me working on it I just have a notepad of what every variable is

Which is bad, but it also helps because it means I can reference what exactly it is without having to find the original script

I can say for a certain, though my code has no memory leaks

That I can confirm

Readability? Who needs that

[haughty bridge]

I highly highly doubt this is the case BUT

could it be because I have an constructor inside of my registries

That’s where I stored the addiction object

[tacit plover]

im not sure, cause the only issue is with the icon

[haughty bridge]

That’s what I was thinking too, but it’s the only thing I did differently than other mods

[haughty bridge]

I think it’s a little funny how my mod is one to one and manages to fuck up

The very fact that I created it is breaking things

Somebody take away my keyboard now before my mods begin to delete the Internet

[tacit plover]

thats part of modding

[haughty bridge]

[tacit plover]

and its also very easy to break zomboid

[haughty bridge]

A game… made in Java… breaking…. No way really

[unkempt rapids]

Hi folks, very dumb question, I'm trying to get started on modling and on 42.12 legacy version via Workshop -> Create and update items -> then I tried to load the sample mod yet it says missing mod.info

is this expected?

[frank elbow]

Do you have a mod.info file? If so, in which folder is it located?

[unkempt rapids]

I do see mod.info file under contents

[frank elbow]

Ah, that template is out of date for b42 (I missed that you said sample, whoops)

https://pzwiki.net/wiki/Mod_structure

[haughty bridge]

The wiki should be up to date on mod structure

[unkempt rapids]

yeah I was looking at this mod structure, but even copy it to C:\Users\Administrator\Zomboid\mods doesn't solve the mod info missing error...

[frank elbow]

It's less to do with the containing folder and more to do with the internal structure, the organization of files into subfolders

Read this section, https://pzwiki.net/wiki/Mod_structure#Mod_folder

You need the folders indicated under b42

[unkempt rapids]

let me give it a try. thx!

[mellow frigate]

I hope someone answered you in the meantime. I do not know. if you are testing in MP 42.13.x, then item changes are supposed to occure server side. check the pinned message for InventoryItem interface changes (Project Zomboid_ API for Inventory Items.pdf), I'm pretty sure there is something about drainable and a specific interface to make them work.

[haughty bridge]

@frank elbow how many mod devs would I piss off I used halo text for debugging

[unkempt rapids]

thx for the hint, yet it shows an different error as there is no contents folders ( which there clearly is...) I'm working on the legacy 42.12 version

[haughty bridge]

All errors appear over heads

[frank elbow]

I imagine most modders test their mods in isolation, so probably not many unless you're also producing the halo text when not in debug mode

[frank elbow]

The contents folder doesn't go within the mod; that's used to determine what's uploaded to the steam workshop

i.e., Contents is the top level folder, which contains mods, which contains subfolders for each mod you want to include on your workshop item (most workshop items just include 1 mod)

[unkempt rapids]

okay...sorry I still don't quite get it. so looking at the current file structure, how should I alter it so the mods can get loaded. do you have any github repo recommendations I can peek into the correct file structure? thx!

[frank elbow]

I don't know any GitHub repos off the top of my head, but the wiki has a tree structure just like that you can reference

The example on the wiki should be interpreted as having an implied Workshop/ModName at the top (i.e., it describes the subfolder structure within that folder)

[unkempt rapids]

so it should be like Workshop/Contents/mods/{MY_MOD} ?

[frank elbow]

Workshop/YourMod/Contents/mods/YourMod

The first YourMod is the workshop item, the second one is the mod

(they don't have to be the same thing, but for a workshop item with one mod it makes sense)

https://github.com/demiurgeQuantified/StarlitLibrary here's a repo example

[unkempt rapids]

just making sure I get it properly, (also I feel being dumb lol, thx for the patience Orz)

[frank elbow]

No need to feel dumb, it's your first time trying out PZ modding. It's entirely understandable to not get things at first

[unkempt rapids]

bravo, this one is so much clearer. I cloned it to the C:\Users\Administrator\Zomboid\Workshop folder and it loads

[frank elbow]

You can thank albion for that, I haven't updated my stuff to b42 yet myself (mp-focused, so was waiting on mp)

[haughty bridge]

Me and saph came to a conclusion my mod is cursed

Nothing will get it to work

I broke it

Even though it’s perfect

https://tenor.com/view/xxiisoul-thanos-gif-23843096

[frank elbow]

Do I want to curse myself by also taking a look 😨

[haughty bridge]

The thing is, it is 1:1 with a working mod

And yet it ain’t

I AM INEVITABLE

maybe it’s a sign I shouldn’t be making a mod about getting addicted to drugs

[unkempt rapids]

okay I've more questions now.... after the mod is created and can be loaded, how to you test it? I can't see it in the mods list...

do I need to subscribe the mod I uploaded to steam to test it?

sounds a bit dumb... like I should be able to test it locally first?

[frank elbow]

I hope you didn't upload that mod 😅 If you did, you should take it down—republishing others' mods without permission isn't allowed

But yes, if you just have it in the folder you should be able to see it in the list & test it

[unkempt rapids]

oh I didn't not upload that one haha

[unkempt rapids]

yeah...weird thing is I don't see is after the game is loaded

[frank elbow]

Are you certain that you copied the mod structure correctly?

[unkempt rapids]

yeah...otherwise it shouldn't load in the workshop right?

[unkempt rapids]

looks good?

ahh I'm missing the common folder as the place holder...

[bright fog]

Are you on mac ?

[bright fog]

Missing common folder

[bright fog]

It's a very recent guide and the whole system is new so it's to be expected

[haughty bridge]

We solved it

It was the dumbest reason

[bright fog]

Ah I confused you with the other guy anyway lmao

[bright fog]

Oof

[bronze yoke]

hmm yeah the game loads the texture and then completely ignores it 😅

[haughty bridge]

It’s not my fault man the wiki was incorrect

[bronze yoke]

the typo was definitely your fault and the first thing you should check 😅

[haughty bridge]

:(

you are banned from JavaScript themed birthday party

[tight elm]

Is this JavaScript guys? 🤓

[tulip valve]

anyone know if StatsDecrease from Sandbox also affects Endurance? Or is it just hunger, thirst and fatigue?

[rich reef]

Unfortunately I haven't gotten a reply for my issue, though I'm sure someone has seen the problem before.

I'm actually using B41 for this on my dedicated server, but will be transitioning my mods over to B42 once it's a bit more stable with MP.

[tight elm]

Just hunger, thirst and fatigue

[raven epoch]

what can i use for dialouge text?

[young trellis]

Where can I label my trait icons to have it reflected in game now, in the scripts .txt file wont show me my icons but I can change the name description etc

[small topaz]

What is currently the way to store something in player's mod data in multiplayer?

[sacred matrix]

I've created a basic Java mod loader. It's very young but allows for hooking methods, adding fields, and registring arbitrary Lua methods. If anyone's interested, let me know.

Additionally, https://theindiestone.com/forums/index.php?/topic/88499-modding-migration-guide-4213/ appears to be deleted. Where do you obtain it from now?

[raven epoch]

guys i need to set an boolean on an isoplayer

how do without another global table to store it

[small topaz]

Global data are usually not required for such a thing (although I don't know your exact setup and there might be exceptions). You can just use lua's module-require commands to keep everything local.

If you want the boolean to be savegame persistent, you should use the player's modData. This works fine in single player without doing anything special. It is pbbly also supposed to work in MP but you need some additional things for using modData correctly which I was not yet able to find out.

[raven epoch]

oh that sounds useful

thanks

me when my mod doesnt work (it felt like breaking)

its not called Add?

am i losing me mind

[tulip valve]

Can this be pinned? It's very useful

[raven epoch]

ok i dont understand this error

it says i tried to call nil in NPCEncounter.UpdateEncounter

[bronze yoke]

tried to call nil means NPCEncounter exists and is a table but NPCEcounter.UpdateEncounter is nil

[raven epoch]

how tho

it works once

then stops??

keeps erroring afterwards

nvm doesnt work at all

it is defined tho

so still dont get it

[bronze yoke]

oh

getTime() does not exist

[raven epoch]

a

[bronze yoke]

your ide even points this out

[raven epoch]

but it existed in

mod optimization page

[bronze yoke]

oh, you don't have umbrella so it says that on everything 😅

[raven epoch]

ye dont have

[raven epoch]

isnt this supposed to

print function bla bla

what does closure mean

[bronze yoke]

lua internal bullshit

technically only java functions are functions and lua functions are actually closures

[raven epoch]

huh

still weird that it prints out in console yet it errors in script tho

[bronze yoke]

the error is from getTime not UpdateEncounter

[raven epoch]

isnt getTime real?

what should i use instead

[bronze yoke]

that page also shows it being defined a couple lines earlier

[raven epoch]

oh

💀

goofy ahh mistake taking up 40 mins

turns out that function doesnt work in singleplayer anyway

so im cooked

[bronze yoke]

it definitely works in singleplayer, i wrote that snippet and only tested it in singleplayer

[raven epoch]

keeps printing 0 on me

i am on b41 might be that

[bronze yoke]

don't remember if i wrote it in b41 or not, it was a while ago

[raven epoch]

yep keeps printing 0

ahh

mb

mb

fixed it

[small topaz]

Has anyone else problems on the steam workshop with the "sorry too many requests" message recently? I am wondering if this is somehow caused by playtesting multiplayer and constantly loggin in and out via the host button...

no it's just all the traffic from the winter sale

doesn't work for anybody

Anyone know the cleanest way to avoid the yellow underline for things like this?

List<String>::get returns type E
So I force the type to string since that is wrong

[bronze yoke]

switch to emmylua

luals has no support for generics

[wet sandal]

Got a link for Umbrella setup on emmylua?

I dont see the addon manager in commands

[bronze yoke]

https://pz-umbrella.github.io/wiki/installation.html

[wet sandal]

Thanks!

Whoa, a lot more visual assistance going on in emmylua

Good. I need it.

My code sucks. My code from 3 years ago sucks harder.

[bronze yoke]

oh yeah, i should tell you the unnecessary-if inspections are often wrong and you should probably just ignore them

you can disable them by adding```json
"diagnostics": {
"disable": ["unnecessary-if"]
}

[wet sandal]

Thanks for the heads up

[bronze yoke]

those are mostly caused by nil checking the results of java methods but we just don't have a reasonable way to tell if a java method can return nil or not so it's usually not annotated correctly

[small topaz]

Is there a simple command to sync player's mod data between server and client? Or is it necessary to do it manually right now?

[wet sandal]

Previously (most) moddata synced itself I thought.

[small topaz]

for me, that seems to be not the case in MP on 42.13...

[wet sandal]

Not sure about now, but I never saw any simple builtin way to do it, I just ended up writing a tiny client/server script for the outliers

What object owns the mod data? @small topaz

Oh, I guess players, based on the question

[bronze yoke]

i didn't think player mod data ever synced but it's been coming up a lot lately so i guess it did...?

[small topaz]

For me, it wasn't necessary to sync modData in B41 so I didn't try. Problem is that in MP B42, the player's modData on client side are not stored in a savegame persistent fashion (i.e. they get lost when logging out). However, on server side, player's modData seem to be savegame persistent but not synced with client side modData (at least according to my testings so far). So my idea to make modData savegame persistent is to (also) write them on on server side to the player's modData. One way to realize all this and to update my mod accordingly would be syncing the modData between server and client.

[wet sandal]

Sounds like I'll need to do this too

[bronze yoke]

ohh right now i remember, it was synced between clients but not to the server

sorry to the people i've misinformed about that lately but it's not like it's relevant to b42 anyway

[shy mantle]

Sooo how DO you sync player mod data to the server now

[small topaz]

But I am not 100% about all this. It is just what my testing suggests to me so far. So don't take everything for granted rn.

[bronze yoke]

you don't, the server sets mod data

[shy mantle]

Wait what

[bronze yoke]

the server should be considered the authority on all data now

[shy mantle]

God damn it I keep forgetting

[small topaz]

yeah... that's also a possible solution: don't sync anything and when accessing modData on client side, always use a sendServerCommand and request them directly from server

[bronze yoke]

i do think it's bad that it's not sent to clients, that should be reported as a bug imo

the clients should be able to read it, just not write it

[shy mantle]

Now the question is, do I push this off for later if they fix that or do I just do the hack now and fix it again later

[bronze yoke]

i wouldn't rely on it being 'fixed' as we don't know if it would actually be considered a bug

but i think they would probably agree that it's an oversight

[shy mantle]

Yeah, I just don't know how long it would take, or if ever, and reorganizing everything is just annoying

I don't want to, but I have to lol

[small topaz]

ofc, clients should be able to write too. but can also manually be done via sendCommands

[bronze yoke]

clients probably should not be able to write or else it invites a lot of potential for exploits with anything that uses that mod data

it could be prompted by the client in some cases but the actual writing should be kept to the server so that it can be sanity checked

[tame mulch]

player:transmitModData() not work for sync?

[bronze yoke]

i haven't tried it in b42, maybe some of the other people here have, but it did not work in b41

[shy mantle]

Ok, well now I'm definitely waiting

[bronze yoke]

i checked the code because i remembered the specific reason it didn't work and it's been completely rewritten and it probably does work now

so someone should try that

[winter bolt]

wait i didnt even know that function existed wtf

[bronze yoke]

in b41 it didn't work for players because it tried to look them up in the wrong object list, it doesn't do that anymore so it probably works now

[tame mulch]

I will check it now. If it will works, I will send example here

[small topaz]

I don't mean "should be able to write arbitrary stuff to modData". But if something specific happens on client side, it might be necessary to change smth about the player's mod data on server side. And from my pov, the natural and ppbly only way of doing this would be sending a command from client->server and then let the server adjust the modData accordingly. That's what I meant.

[tame mulch]

sync modData works!

[tame mulch]

Usage:
Right Mouse Click on any world object (for example, floor) -> Option "SyncModData"

[tame mulch]

client code:

local function printClient(playerObj)
    local data = playerObj:getModData()
    print("Player ModData:")
    for k, v in pairs(data) do
        print(k, " = ", v)
    end
end

local function printServer(playerObj)
    local args = { id = playerObj:getOnlineID() }
    sendClientCommand(playerObj, 'player', 'printPlayerModData', args)
    print("You can check player ModData in server logs")
end

local function addData(playerObj)
    local key = ZombRand(100000)
    local value = ZombRand(100000)
    playerObj:getModData()[tostring(key)] = value
    print("Value added")
end

local function syncData(playerObj)
    playerObj:transmitModData()
    print("ModData sync done")
end

local function OnFillWorldObjectContextMenu(player, context, worldobjects, test)
    local playerObj = getSpecificPlayer(player)
    local subOption = context:addOption("SyncModData")
    local syncMenu = ISContextMenu:getNew(context)
    context:addSubMenu(subOption, syncMenu)

    syncMenu:addOption("Show player ModData (Client)", playerObj, printClient)
    syncMenu:addOption("Show player ModData (Server)", playerObj, printServer)
    syncMenu:addOption("Add Random Data to ModData", playerObj, addData)
    syncMenu:addOption("Sync ModData", playerObj, syncData)
end


Events.OnFillWorldObjectContextMenu.Add(OnFillWorldObjectContextMenu)

[tame mulch]

server code:

local ClientCommands = {}
local Commands = {}

Commands.player = {}
Commands.player.printPlayerModData = function(player, args)
    local otherPlayer = getPlayerByOnlineID(args.id)
    if otherPlayer then
        local data = otherPlayer:getModData()
        print("Player ModData:")
        for k, v in pairs(data) do
            print(k, " = ", v)
        end
    end
end


ClientCommands.OnClientCommand = function(module, command, player, args)
    if Commands[module] and Commands[module][command] then
        local argStr = ''
        if args then
            for k,v in pairs(args) do argStr = argStr..' '..k..'='..tostring(v) end
        end
        Commands[module][command](player, args)
    end
end

Events.OnClientCommand.Add(ClientCommands.OnClientCommand)

[tame mulch]

playerObj:transmitModData() that called on server must work too

[upbeat turtle]

ty aiteron!

[small topaz]

if we can use transmitModData() on client side and thereby force the server to sync server modData with client modData, wouldn't this in theory also be a possible source of cheating and exploits? Other way around wouldn't matter ofc. But maybe I just misunderstand (and ofc, for us modders this provides an easy way of doing stuff).

But on the other side: A possible cheater could in theory always add some weird "send-to-server-commands" to their client code and manipulate the game thereby to a certain degree (depending on how the handler functions on the server are written). Only thing is that by having this option to sync all mod data at once by just a single command, they maybe even more felxible for cheating the game....

[small topaz]

so it's basically the problem albion already suggested above if I get things right: by using transmitModData() on client-side, the client has basically unrestricted possibilities to write stuff to modData

[wet sandal]

@bronze yoke
Sorry to keep bugging you, just a weird question. No worries if you don't know.

I somehow deleted the definition of InventoryItem while using emmylua?
Any idea how that happened so I can avoid it happening again?

Umbrella is in ~/Zomboid/Umbrella
The mod i'm working on is in ~/Zomboid/mods/EquipmentUI/42.13/media/lua/ <-- This is where I have the VS Code project open
~/Zomboid/mods/EquipmentUI/42.13/media/lua/.emmyrc.json for config

I was working on stuff and at some point InventoryItem just became unrecognized.

I went to the Umbrella folder and git status was lit up for basically the entire thing.
git reset --hard got me fixed up, so no big deal. Just curious how I managed that.
Did I flub some weird key combo?

[bronze yoke]

no, i have no idea how you could've done that by accident 😅 i'm not aware of anything like that

[wet sandal]

Lol, yea no clue what I did lol

Oh well

Figured out replication.
You can rename umbrella definitions.
Must've accidentally renamed the class while trying to rename a variable

[bronze yoke]

😭

[frank elbow]

Why on earth would EmmyLua allow that

[foggy finch]

I have a quick question, how can i create like my own menu on the side bar, and have its own icon? So like the Health Menu when in game, but for my own? And is there something of style like a TextBox that exists where i can make it "read only" and just put anything into it whenever i want, more like whenever needed? Also, is there a possibilty of randomness, so like i want to list all the food items, randomly select one, and then give it to the player?
P.S. Its not really a quick question, i just wanted to do 2 birds 1 stone

[haughty bridge]

This may be a little bit of a dumb question, are there any wiki articles on making library mods, like ones you can retrieve via require?

[wet sandal]

Any lua file can be loaded using require().
Generally all you need to do is declare a local obj, stuff all your functions inside it and return it at the end of the file.

i.e.

[haughty bridge]

Well yeah but I mean requiring a workshop mod for example

[wet sandal]

Oh

[haughty bridge]

So like say I make a lib that handles X task

How would other people be able to reference

[wet sandal]

2 layers to that

One you manually define on the workshop page

The other goes in mod.info

name=Inventory Tetris
id=INVENTORY_TETRIS
description=A full grid-based inventory overhaul for Project Zomboid.
require=\EQUIPMENT_UI
poster=poster.png

Tetris requires EQUIPMENT_UI

[bronze yoke]

to make a lua file requirable you just need to return something at the end```lua
local myModule = {}

-- require("filename") will return this table
return myModule

all a mod requirement does is not let people enable the mod if that one isn't enabled, it doesn't do anything else

[haughty bridge]

Well, I know all about requiring. I just didn’t know how to set it up so you can require a workshop mod for example.

[winter bolt]

from what i can find it looks like that sidebar ui is set up in lua/client/ISUI/ISEquippedItem.lua so it should definitely be possible to insert your own button in there

[civic galleon]

I am attempting to move a mod's logic server side. Does one just place the .lua files in media/lua/server instead of media/lua/client? Not even top-level print() seems to be coming up in the server-console.txt having done this.

[bronze yoke]

if the top level print isn't working that's something else, but usually moving the files is not enough

[haughty bridge]

I’m so used to psede that I keep trying to require stuff via @self or @psede

[civic galleon]

content of the mod aside (Im looping through the results of getOnlinePlayers()) I am struggling to figure out the missing piece. My declared functions fired no problem client-side. The functions are designed to run on EveryOneMinute. It is strange not even top level is hitting the log.

[bronze yoke]

yeah that's really odd, everything you've mentioned should work on the server

it should be noted that files in the server folder do also run on the client, if you don't want this to happen you can start the file with a check like this:```lua
if isClient() then
return
end

how are you hosting the server?

in-game hosted servers log to coop-console.txt, not server console

[civic galleon]

steamcmd dedi

[civic galleon]

I will add this! I was unaware /server ran on both client and server. I assumed that's what /shared was for hahahaha

[bronze yoke]

yeah, and /client *does* only run on the client so god knows what's going on here 😅

[sour island]

Can trasmit also include a key argument to transmit just that key/value? That way if a mod needs to sync its data it doesn't have to send the entire modData table?

In the past mods sending the entire table could hit a memory/data threshold

[foggy finch]

that helps part of the question, but i dont know for the food stuff.

its fine if you dont know how to, but i was just wondering

since id want to do that

[winter bolt]

the game ui is all lua code so you can definitely do all of that but the ui code takes a while to wrap your head around

for the food stuff you could probably loop through every item in the script manager and filter them by food items if you wanted to automatically grab every food item in the game or you can make your own list of items

[small topaz]

Have a very specific question about visibility of clothing items worn by players in MP.

My setup: In client code, I equip a clothing item to the player. The item is not in player inventory and the player cannot interact with the clothing item, which is intentional since it only servers as some visual "sugar". This works fine for me when play-testing alone via the host button (also fine in single player).

Question: When other players are around, can they also see those "visual sugar" clothing items? Or is it necessary that I shift my code to the server to properly sync everything?

Just asking cause when play-testing alone, I cannot check how the system behaves if other players are around ofc.

[winter bolt]

other players arent able see it

[foggy finch]

Yeah figured that doing a loop was somewhat quicker

im gonna endup doing that

[tame mulch]

No, :transmitModData() send full copy of table. If need send only one key/value - better to use sendClientCommand, sendServerCommand

[small topaz]

thanks for the info. (I guess you already know it from your character creation mod...?? 😉 )

[sour island]

Yes, Im asking if this can be changed 😄 - so sending just 1 key/value can be natively supported

[winter bolt]

yeah ive unfortunately had to spend the last week straight figuring out how all of the clothing syncing works lmao

you'll definitely want to test mp for your mod though by adding -nosteam to the launch options so you can open multiple clients

[small topaz]

I'll now have to go through this topic too for my mod XD XD XD

and I don't want to XD XD XD

[winter bolt]

onclothingupdated only runs on each client so if you need to mess with any items in it you'll need to do a sendclientcommand in there

[civic galleon]

are we not able to modify player stats completely from the server, without any code running on the client?

[small topaz]

even if it's triggered on server side?

[sour island]

I've made client/server commands to sync modData - but not everyone is comfortable using commands and I've seen multiple cases where a mod abuses transmit to the point of packets getting lost and the console spams 'cannot find X of null (isoPlayer)'

[winter bolt]

apparently when you trigger an event like that it only triggers it on the same side?

[small topaz]

therefore I asked. but I misunderstood your previous remark, then. my bad.

[winter bolt]

singleplayer runs server code so it will trigger there but in mp the clients wont be affected by it from what i tested

in your case i think you'd have to just check if the item should be visible or hidden and then send the appropriate client command and it'll work fine

[tame mulch]

I think I won't change how JAVA transmitModData() works. But, maybe I will add some syntactic sugar for modders. Like:

playerObj:transmitModData() -- Java function call
playerObj:transmitModData("myCoolParam") -- sync ModData param by commands

Hmmm, but need check edge cases

[small topaz]

When on server-side in MP, how do I get a list of all players currently in the game?

[winter bolt]

getOnlinePlayers()

[sour island]

This is exactly what I would suggest -- keep the original method, but allowing an optional specific 'check/replace for this key' would help newer modders out

Do the Events OnNewGame and OnGameStart have some server side equivalents? So, an event which is triggered on server when a player with a new character joins game or a player starts or loads/relogin to a game?

Or can I even use those commands in the "intentional" way directly on server? For example, OnNewGame is triggered on server when new player joins? (Wiki says "(client)" for this command but not sure if it is up to date)

Are comments on Steam mods broken for everyone, or am I being targetted for daring to open the comment sections of three mods at once?

OnCreateLivingCharacter but you need to check if the character is an isoplayer as well as not an isoanimal

it triggers on any player joining though even if they just came from character creation so i ended up just using the client functions and using sendclientcommand instead
