i want to remove whats inside the weapons

[halcyon marlin]

thanks, this is super helpful, and I am afraid that your second message is the case, but I am going to keep looking

[halcyon marlin]

also should have mentioned that i spotted this, but i do appreciate your help

[jaunty marten]

[halcyon marlin]

i am trying to make some adjustments to the Please Don't Feed the Zombies mod that just hit the front page for my own use to make it a bit more like the walking dead. I have tried a couple times to mod PZ but couldnt get past scripts really, so you are a big help

[sour island]

And for my next trick: https://cdn.discordapp.com/attachments/821080036320346152/995157725296210021/ProjectZomboid64_2022-07-08_22-41-23.gif

[jaunty marten]

I have next idea for mod to u
Fast enter to vehicle cos even by Z it's still annoying cos menu opens not always

[sour island]

you use the menu to enter?

and not just E

[jaunty marten]

need to aim to vehicle door xp

even in one of ur last gifs from ur last mod u entered in vehicle only after 5 times

[sour island]

while it was moving?

[jaunty marten]

tbh u professional

[sour island]

🤌

ty

[jaunty marten]

I not always can enter by one time even in not moving vehicle

[sour island]

you dont really need to wait for the green to come up

[jaunty marten]

maybe I have bugged keyboard

but doesn't work for me

only with green

[viral flame]

Hey I made that!

I'm curious why you don't want zombies eating humans that were killed twice?

I haven't been able to test much in multiplayer, does it mess with the game in some horrible way I haven't considered or is it just preference?

[halcyon marlin]

lol i havent really tried it with multiplayer but i was trying to get it so that the zombs would only munch on npcs who died (until they would turn into zombies themselves) or zombies who spawned dead in the world already because i guess in The Walking Dead lore they dont eat other zombies after they died because of rotting flesh and whatnot. I think your mod is really cool, i was just trying to tailor it to my preferences a little more

[viral flame]

Ahh, makes sense - hadn't thought about NPC mods. I'll make a note to add a config for only non-zomboid corpses to be eaten.

Thanks!

[halcyon marlin]

thanks for reaching out! if I can get it to work as I'm intending I will let you know how I did it. I'm not an expert or anything, so honestly you would probably beat me to it, but I'll try

[viral flame]

Lol, sounds good

[random finch]

Ah ha, appreciate that.

[random finch]

My man. You made a mod that allows you to pull people out GTA style?

[sour island]

ye

[random finch]

When is this going up on the workshop? I wanna test it.

[sour island]

probably like in a hour

gotta work on the most important part - the workshop poster

[random finch]

yehh yuhh

[random finch]

There a simple way to get rid of a players shadow without impacting any other shadows? Used masks on an item to hide the model.

[thin hornet]

Item EatType
doesn't seem to work properly when
ReplaceInSecondHand and/or ReplaceInPrimaryHand is set.

kind of prevent the EatType animation to works.

[jaunty marten]

how to use bit lib in pz?
Bits returns nil
utils same

[viral flame]

you can't, you can only access classes that are exposed

take a look here if you have decompiled the game

[jaunty marten]

[thin hornet]

yo wheres that new ATM tile

[jaunty marten]

now I have to create bit lib in game where one already exists but I haven't access to it

what a shit

[thin hornet]

I found the new safe

but no atm yet

ah there it is

jeeez its tall lol

[tidal kayak]

atm machine 👀

[viral spire]

Is there a mod out there where we can set a weather/season event to last for a specified period of time? Say I start the game in July but I want a winter event to kick off in 30 days, but it'll last for 6 months, so I need to prepare in that time and then work to survive the time after that. This is to simulate events such as an impact winter from asteroid impact, or a nuclear winter from a nuclear war (with subsequent mods added for effect).

[stark cradle]

How can I add a new type of zombie? I want to replace most if not all zombies with a certain few models that I made for enemies. I just want them to spawn like other zombies and maybe have a few special actions like lunging themselves at players. I'd be grateful just for a way to add a new zombie type though, really.

[wooden falcon]

Anybody know why my solo world mods are all of a sudden using my steam workshop versions of my mods and not the local versions in my /Users/*/Zomboid/workshop folder? Any changes I make to those mods don't get picked up by game unless I unsubscribe from the steam workshop version of that mod.

[thin hornet]

Yeah I do have the same behavior for SP

[wooden falcon]

Do you remember it always being like that? I'm pretty sure I used to be able to be subscribed to my mod, but still able to tweak it from my /Users/ folder and still get the change effects after a lua reload.

[thin hornet]

If I recall correctly it was not like that in the past

But its been a while since i test my mods in SP, usually use local server or host

[static girder]

Hey all. I'm fairly new to modding PZ and I'm trying to find a way to increase the base capacity of containers (such as crates). However, I was unable to find where the base capacity of furniture is defined.

Alternatively, I tried looking into modifying the "Organised" trait's multiplier (to effectively increase the capacity of all containers) but I was also unable to find where this variable is defined.

Any help on either of the above issues would be greatly appreciated!

[thin hornet]

I think youll have to use the tile software to check the tile definition

TileZed

[static girder]

@thin hornet Thanks! I'll set it up and see if it helps

[thin hornet]

Im not sure you can edit vanilla tiles tho

[pearl prism]

I could be wrong, but as far as I know mods that change the capacity of the contenders tend to cause problems in the game

[static girder]

@pearl prism That would definitely explain the lack of mods tweeking base capacity of containers. What about going down the route of modifying the value for the Organised trait?

[thin hornet]

Most of time traits are handled on the java side (so not really editable)

[static girder]

@pearl prism @thin hornet So if base traits are not editable, what about creating a new custom trait that would behave the same as "Organised" but with a higher multiplier? Or would that also involved adding something on the Java side?

[thin hornet]

So for example:
zomboid\zombie\inventory\ItemContainer.java

   public int getEffectiveCapacity(IsoGameCharacter var1) {
      if (var1 != null && !(this.parent instanceof IsoGameCharacter) && !(this.parent instanceof IsoDeadBody) && !"floor".equals(this.getType())) {
         if (var1.Traits.Organized.isSet()) {
            return (int)Math.max((float)this.Capacity * 1.3F, (float)(this.Capacity + 1));
         }

         if (var1.Traits.Disorganized.isSet()) {
            return (int)Math.max((float)this.Capacity * 0.7F, 1.0F);
         }
      }

      return this.Capacity;
   }

you can create new traits but you cannot add the effect to that function getEffectiveCapacity

You will need to research there is maybe a function or something that would allow you to do something but not that I know personnaly

[pearl prism]

I believe the big problem is that the game first reads the original code and then reads the mods' codes, so any attempt to change any vanilla system tends to give an undesired result. The way it is possible to change contender storage capacity would be to simply create an entirely new furniture from scratch, that way the game would only read the mods codes.

[thin hornet]

Well basically the game engine is made of Java, it include a Lua interpreter that exposes a set of functionality that we can use in our Lua mods. So we are limited to what is exposed and cannot overwrite any thing of that java stuff.

[outer perch]

hi, I am having an issue where any items I drop on the ground get deleted, any ideas?

[thin hornet]

@outer perch dropping like mouse dragging it down?

[outer perch]

yeah

[thin hornet]

you are using mods?

[outer perch]

yeah a lot

[static girder]

@thin hornet @pearl prism I see. Got it, thank you both!

[outer perch]

but it just started happening

when it wasnt

[thin hornet]

you are on the unstable or stable beta?

[outer perch]

stable as far as I know

[thin hornet]

try changing for unstable

thats the latest released

[outer perch]

ikr

but

will that not break any other mods doe?

[thin hornet]

it can

[outer perch]

:(

[thin hornet]

So you are having that issue in SP or MP?

[outer perch]

mp

[thin hornet]

anyone else having it?

[outer perch]

yeh

my friend

I found this: The mod causing it is Arsenal/Brita's Weapon pack. Unsubscribe and resubscribe to it to fix the bug from the integrated Eris Nightvision mod.
but probably outdated eh?

[thin hornet]

no idea

[outer perch]

meh

Paw Low and Britas are causing issues. Redownload Britas and download this unofficial patch for Paw Low to stop disappearing item issue.

I guess that might make some sense

will try this

got both oth them

okay, fix from reddit

This worked for me, thanks

Closed the game

Unsubscribed from both Brita's mods, Paw Low, etc.

Resubscribed, including the Paw Low patch

Watched the workshop content download in Steam

Launch the game, make sure they're all enabled (including the Paw Low patch)

Continue save - success!

How is the guid for custom items produced?

Ah it appears I can use a generator. ItemZed also produces a guid but Ive never used it, not sure if its still updated.

[willow estuary]

ItemZed is horribly out of date; I'd suggets manually editing script files instead?

I use this to make GUIDs
https://guidgenerator.com/

[random finch]

Very good. That's the one I came across.

[cosmic condor]

Or use this extension if you're using VS Code https://github.com/heaths/vscode-guid

[jade musk]

are there any mods that increase the storage size of containers?

[cosmic condor]

A LOT

[jade musk]

i havent found any that have been updated. can point me to one?

[stark bone]

Hi, I have a question. Does anyone know how to make a mod pack? I did like to play with my friends with some mods but usually its like one of us have late version and we cant play

[cosmic condor]

I'm not sure which one is good. I would make one if I want to use something like that

[cosmic condor]

Do you mean, a mod collection that allow you to subscribe or literally a single mod that contains all mod that you want?

if you mean the first option then go here

when you have a problem just sub and unsub all mods in the collections

and delete all workshop in local folder

then resub again

[stark bone]

rather something like "Snake's Mod Pack" or server packs. One mod contains multiple mods.

its like all in one

[cosmic condor]

but remember modders dislike the idea because it takes all of their time and effort

ask for permission first

[stark bone]

after thinking that it may be invasive for them, I will probably give up because I have literally LOTS OF mods i did like to play with bois but still thanks for help, I learned something new

[cosmic condor]

better add those mods into your collection, good for everyone

also take a little effort

[halcyon walrus]

Hey, working on making a gun mod but run into a slight issue with the positioning of the rifle. Its kinda low down on the character and doesn't sit right in the hands. I tried adjusting the models position in blender but all that seemed to do was distort the model in game. I'm pretty sure it's a script I'm looking to edit in the firearm.txt file but I really have no idea.

[cosmic condor]

Maybe you can search for an old post. I guess some people have encountered this issue.

[dapper vector]

Is there some replacement to the UseItem event?

[heady crystal]

Anybody know how to get the item or item name of a vehicle part?

[heady crystal]

Not sure what I am supposed to do with that information

[sour island]

Anyone know of a way to ensure your mod is loaded before someone elses? like an anti-require?

[placid hinge]

local vehicle = playerObj:getVehicle()
local vehiclePart = vehicle:getPartById("Part_name")

@heady crystal

[heady crystal]

That'll give me the part

I need the item specifically

The inventory item

[placid hinge]

Oh thought you meant just in the lua, should be able to spawn it in by the ID too

local playerObj = getPlayer()

local vehicle = playerObj:getVehicle()
local vehiclePart = vehicle:getPartById("Part_name")

[heady crystal]

I have the vehicle but I want to get it's parts and give it to the user as items

But inventory:AddItem(PARTHERE) won't work with anything I tried off the part

ID won't work, getfulltype only returns the part not the item, etc.

[placid hinge]

Oh yah than this should work, use vehiclePart and put the ID in getPartByid()

to do inventory:AddItem(vechiclePart)

[heady crystal]

That doesn't work

I already tried it

It expects the item name string

Say I want to add a vehicle's front left wheel

I'd have to do for instance inventory:AddItem("Base.NormalTire1")

[placid hinge]

Oh really and yah that should work to get it in item form if thats its name

[heady crystal]

Yes the problem is how to get it's name off the part?

How to get it's name at all

Nothing works

[placid hinge]

Oh you mean just the display name?

[heady crystal]

No, like this

Which translates to Base.NormalTire1

[placid hinge]

Yah thats its normal name, should be able to work with it as such, otherwise idk really

[heady crystal]

Yes but how do you get that property off the part?

[opaque ocean]

can someone please explain to me what the heck MetalValue is? I keep seeing it in a bunch of unrelated mods but I can't figure out what it's used for.

[sour island]

Metalworking recipes

metalworking was/is a planned skill - there's alot of stuff referencing it in the files - alot of modders added it in/make use of it.

[opaque ocean]

alright, so it's a useless item property until 2025?

[sour island]

alot of modders added use for it

if you want your item to be interactable/metled down/etc idk not really a big deal

[opaque ocean]

fair enough. Thank ya for the quick response my dude! Working on an overwrite to integrate ISA into hydro right now to replace Hydro's bugged solar generators. Finally got around to testing the ISA patch and it actually fixes the cell unloading issues that Hydro still has.

[wooden falcon]

For Events.OnKeyPressed, is there somewhere where we can see the mappings between keys and their corresponding numbers?

trying to make painted and plastered walls invincible and untouchable by zombies, but this code doesn't seem to work, do you guys know the issue?

[tranquil reef]

Would it even be remotely possible to get blender shape keys to work in zomboid

[rancid verge]

Does anyone know the function for modifying the speed a zombie is able to walk through trees? I'm new to modding and not sure where to look

[drifting ore]

can i overwrite existing walls to not be thumpable via plastering/painting or both?

[cosmic condor]

I guess it's the unicode character order. If you want them to load before any other mods, place these ASCII Punctuation & Symbols before your mod id, but avoid the one that will break the code.
https://en.wikipedia.org/wiki/List_of_Unicode_characters#Basic_Latin

those who want their mod to load later, can also apply this method

I saw someone recently asked here but deleted the text

[cosmic condor]

should it be
getPlayer():getInventory():AddItem("Base.NormalTire1"); ?

[heady crystal]

That's not even remotely close to what I asked, but it's ok, I already found a way out. Thanks anyways.

[cosmic condor]

post your solution here, in case anyone searching for the solution

... and what is your question exactly? I read many times and still don't understand what you really need

[shadow geyser]

you are welcome to come and send the code to the hydrocraft discord or make a pull request in to the hydrocraft github and I can merge it in, crediting you ofc. would be nice to fix any compatability issues with the main mod rather than needing additional patch mods we might break in the future. that way if we make any changes in the future, we wont break your stuff.

[opaque ocean]

I mean, I gave you the clay molds recipe naming fix, but it's less of a patch and more of an integration of ISA for our server, would prob not be everyone's cup of tea and would make ISA a dependency for Hydro.

unless you wanna hitup Radx5 and Neznajka and fully bring ISA into hydro, it's not something you want in the main mod

[unique goblet]

I'm having trouble sending ModData from client to server. Wiki says that OnReceiveGlobalModData is triggered only on client side whereas indiestone forum says that OnReceiveGlobalModData is triggered on both client and server side. I am suspecting that first option is true, because is seems that client is transmitting ModData but server isn't receiving it.

Code shared by client and server:

    if key~= "MyModData" then
        return; 
    end
    if not modData then
        print("modData table is missing");
    else
        ModData.add(key, modData);
    end
end

Events.OnReceiveGlobalModData.Add(OnReceiveGlobalModData);```

When I send ModData from server to client using `ModData.request("MyModData")` it works just fine. But when try to send modData the other way around from client to server using `ModData.transmit("MyModData")` then modData table on server doesn't update and stays in same state as before `ModData.transmit("MyModData")`

So does transmitting ModData work differently depending on direction of transmission or it does work the same way and I am missing something else?

[thin hornet]

instead of transmitting the whole table you might want to use sendClientCommand to transmit just the changed values to the server.

Client:

-- if ModData.exist("MyModData") -> ModData.delete("MyModData")
-- ModData.create("MyModData")
-- ModData.request("MyModData") -> we get the most up to date
-- OnReceiveGlobalModData -> set moddata on this client

Server:

-- ModData.getOrCreate("MyModData") -> persistant moddata
-- OnClientCommand -> handle client command -> update MyModData fields
-- sendServerCommand -> tell everyone online about the changed field

only the server should be trusted, so if a client was sending a whole modata table, it would replace the server one with it and could potentially cause loss.

Does anyone have any idea where I could find the Lua code that deals with weight loss and gain? I've scrounged around the code and came up empty. I really want to make some kind of "weight loss pills" mod for multiplayer specifically. 🙃

[drifting stump]

its java side

instant weight loss should be simple however

[thin hornet]

Take a look at my mod https://steamcommunity.com/sharedfiles/filedetails/?id=2827714166 it might help you

[steel locust]

Thank you! Great mods by the way, I use your server messages and death messages on our server. 🙂

[jaunty marten]

I'm really don't like pz cos I need to create folder with my mod name in each realm folder instead just media/lua/mymodname/[cl/sv/sh]

[thin hornet]

yeah thats a bit anoying but can also help

cause inside lua/client and lua/server we often have other stuff like Translate Items etc

so submodname directory help separate your logic from all the rest of it

it also help with the require require 'ModName/file

[jaunty marten]

yea, rn it's no way to remake cos will break everything xp

[sour island]

Hm, that could be helpful - I was trying to patch my mod for another person's mod but I ended up just using a if check for the other mod being active - forcing a require and rerunning part of their mod inside of my own.

[thin hornet]

Load order should really be handled with require

require force the required script to be loaded first, if using require on a already loaded script it wont run it again it will just return its cached value

reloading a script re-run that script and update its cached value

A mod depending on an other:

if getActivatedMods():contains("TheRequiredMod") then
  require("TheRequiredMod/script"); -- ensure that mod script is loaded now before continuing
  
  -- we gucci

else

  -- we gucci without it

end

When making a mod a possible pattern to ensure files load order:
client/Main.lua

require 'Utils'; -- ensure utils has been loaded first, will be available in all other files then
Main = {};

shared/Utils.lua

Utils = {};

client/Module1.lua

require 'Module2'; -- ensure Module2 has been loaded first
if Main then print("Main exist"); end
if Utils then print("Utils exist"); end
if Module2 then print("Module2 exist"); end

client/Module2.lua

require 'Main'; -- ensure Main has been loaded first
Module2 = {};
if Main then print("Main exist"); end
if Utils then print("Utils exist"); end

[drifting stump]

that isnt a module

and stop using globals already

client/Main.lua

local Utils = require 'Utils'; -- ensure utils has been loaded first, will be available in all other files then

local Main = {};

return Main

shared/Utils.lua

local Utils = {};

return Utils

client/Module1.lua

local Module2 = require 'Module2'; -- ensure Module2 has been loaded first
-- if Main then print("Main exist"); end
-- if Utils then print("Utils exist"); end
-- if Module2 then print("Module2 exist"); end
-- these are not a good way of doing things, require is how you ensure something is loaded. Check instead if a mod is loaded to make sure the require can happen

client/Module2.lua

local Main = require 'Main'; -- ensure Main has been loaded first
local Utils = require 'Utils'
local Module2 = {};
if Main then print("Main exist"); end
if Utils then print("Utils exist"); end

return Module2

for a file to be a module it needs to return something
whatever is returned is given when requiring somewhere

when invokes event OnObjectAboutToBeRemoved? I'm using next part to delete obj but event doesn't invoke

square:transmitRemoveItemFromSquare(obj)
square:RemoveTileObject(obj)
square:DeleteTileObject(obj)

or mb there's other event when obj deletes

nothing else but OnObjectAboutToBeRemoved on wiki

ah, it's lua event
but then how to catch real remove of object? basically I need to catch event when object about to remove by sledgehammer so need to catch transmitRemoveItemFromSquare or RemoveTileObject

[shadow geyser]

looking at the pz code, I think you want to use OnDestroyIsoThumpable. That is the sledge hammer action calls atleast. However it calls it in an unusual way by using sendClientCommand. But I think that should work for the sledgehammer case. However for the :transmitRemoveItemFromSquare(obj) and the rest. you can just call the function you would insert to the event handler instead, as they might not trigger the an appropriate event anyways

[pulsar rock]

Hey all. Not new to programming / LUA / etc..., definitely new to Zomboid modding. How do I get the PZ Library jars?

[jaunty marten]

https://github.com/Konijima/PZ-Libraries

[shadow geyser]

you can decompile the PZ. there is a guide in this channel somewhere. just search decompile

[jaunty marten]

thanks

[jaunty marten]

ah, it's clientside event, fk, missed it

@willow estuary sorry for ping but mb u know how to catch when object is about to be remove?

[pulsar rock]

So, why is CAPSID running some kind of "createDiscordIntegration" gradle job?

Nvm, found it

https://github.com/pzstorm/capsid#discord-integration

For anyone curious

[willow estuary]

Sorry, I don't have an answer for you regarding this.

[jaunty marten]

[jaunty marten]

btw, can I ask u to add bit lib on lua side? or dev who doing stuff like this
I have one but it's done by lua. be better by java

the only thing I'll wait in future updates

[fast galleon]

I believe it's SP and server event

[jaunty marten]

yea, u should do triggerevent here

[fast galleon]

oh right, I was thinking about remove event since I've had issues with that

[jaunty marten]

how did u solve thses issues?

my issue is to remove object from cluster when it was broken by sledgehammer cos I don't want to check if object is valid in iteration of this cluster

[pulsar rock]

So, what function should I override to prevent XP gain for certain skills?

Would I override the AddXP function?

Or is there an event that is raised when a player gains XP?

Could just reduce XP by the same amount when it happens

Thought that feels like it'd be somewhat performance-problematic, potentially

Ah, found it

[thin hornet]

its just an example

[thin hornet]

nothing wrong using globals if done properly, i mean pz is made of globals lol

[drifting stump]

everything wrong with using globals

[thin hornet]

pz is 90% made of globals

[drifting stump]

and?

[thin hornet]

and because of that you can hook and mod it

[drifting stump]

and?

[thin hornet]

and the same apply to a mod

[pulsar rock]

Right, but LUA's philosophy is keeping scope as small as possible

It's bad practice to use globals if you don't need to

[drifting stump]

^

[thin hornet]

Yeah that why i said if done properly

[pulsar rock]

"Done properly" is a very vague statement

[drifting stump]

but using a global is always not done properly

[thin hornet]

basically use a single global that contains everything else

[drifting stump]

look

[pulsar rock]

[drifting stump]

if you do

local var = {}

return var

local var = require "whatever that file is"

you have access to the same var

[thin hornet]

sure

[drifting stump]

why would you ever use a global instead of this

[pulsar rock]

Deja vu

[thin hornet]

i mean i know this

lol

[drifting stump]

then why are you advocating for globals

[thin hornet]

coz we live in a globalist world now

lol

[pulsar rock]

So, question; I'm new to PZ modding. I'm working on a mod that caps your maximum skill level based on your traits / profession.

[thin hornet]

mhm

[pulsar rock]

Where would I grab the list of skills, traits, and professions?

[thin hornet]

the global Perks

[pulsar rock]

I'm currently just planning on hooking into the AddXP Event. Can you "cancel" an event somehow?

[thin hornet]

you can hook into onAddXp

and there you kind of cap/max it

[pulsar rock]

onAddXp?

The wiki has an "AddXP" event, but I can't seem to find an onAddXP one

[drifting stump]

gonna write the localist manifesto
we localists now

[pulsar rock]

I guess I could also grab LevelPerk

So, how does one "cancel" an event?

[thin hornet]

Events.AddXP.Add
Events.LevelPerk.Add

[pulsar rock]

Aye, but you can't cancel the event somehow, can you?

[shadow geyser]

btw what was the issue with using OnObjectAboutToBeRemoved event? when looking in the java, it should be triggered when isoobjects are removed from a tile

[thin hornet]

no but you can remove xp and limit the perk level

[pulsar rock]

How would I limit the perk level?

Or simply reduce back to my limit if they level up?

[thin hornet]

well if > limit = set it back to X

[drifting stump]

you could use the perk level event and bump it back down

[pulsar rock]

I guess

Is there any unlocks that happen if you level up?

/ any weirdness to take into account

[thin hornet]

i dont see where AddXP event is triggered but LevelPerk is triggered at the end of the functions so if something was added it will probably already be added when LevelPerk is triggered

[pulsar rock]

Ah well

I guess I can just hook into LevelPerk for now

[thin hornet]

i suggest you read zombie\characters\IsoGameCharacter.java

[pulsar rock]

Not too hard to change it to AddXP, if necessary

And saves on a fair number of calls

[thin hornet]

LevelPerk is triggered when Losing a level and Gaining a level

[shadow geyser]

@thin hornet hi wasn't sure what the best way to communicate with you, but I was having some problems while following your guide for decompiling. after executing the setupWorkspace it ran all task mostly the same stuff except it ran "compileZomboidLua" instead of "compileZomboid" (not sure if that matters)? but ultimately I dont see the build folder and therefore no sources directory. Is there some mistake that needs to be fixed? I dont have any previous experience with gradle so im not sure what information is relevant

[thin hornet]

dm me with a screenshot of intellij workspace

just wanna see what you see

[pulsar rock]

That's fine @shadow geyser

Or, well, the name difference is fine

Refresh your directory?

Also, @thin hornet, is there some way to get the amount of "pips" a player has per skill?

Like, what do these represent data/code-wise?

[thin hornet]

the green bars?

each bar is 1 level

[thin hornet]

i suggest you check theses files

youll find reference about how to set level etc

[jaunty marten]

pz is 99% made of
better don't use parts of code from there

[jaunty marten]

idk, it doesn't call

[thin hornet]

did you try OnTileRemoved

[jaunty marten]

okay I just tested again and it start to invoke func

wtf

[thin hornet]

Sometime when using Reload button

it just fuck it up

so you have to go back to menu and log again

[jaunty marten]

I press this button 3-5 times each time

[jaunty marten]

ah

[thin hornet]

XD

[jaunty marten]

pz

[thin hornet]

press only once

xD

you should see in the console that it reloaded it

but even tho

Events dont like reload

especially when using anonymous function

[jaunty marten]

in 90% reloads

[thin hornet]

Events.OnTick.Add(function() end);

[jaunty marten]

idk how it even can work cos it haven't any id for event

[jaunty marten]

yea, it's my way

[thin hornet]

😮

dont 😛

use globals

xD

nah but better store that function in a var before passing it

[jaunty marten]

but anonymous func is better...

[thin hornet]

local function onTick()
  Events.OnTick.Remove(onTick);
  print("run just once")
end
Events.OnTick.Add(onTick);

also when reloading your script with this, the old onTick reference become nil

anonymous i dont think it nullify it

[jaunty marten]

Yea, Ik but for func that shouldn't be removed I want to use anonymous func :(

[thin hornet]

Just try to use local function instead from now on

[jaunty marten]

[thin hornet]

its not javascript xD

😛

[jaunty marten]

why are u making me cry

[thin hornet]

https://tenor.com/view/evil-laugh-the-dark-knight-gif-24880014

My plan is to start using globals and anonymous functions everywhere

[pulsar rock]

Right, but can you somehow check what your starting level for them is?

For example iterating over traits + profession and checking what they add?

Or is it not that simple?

[thin hornet]

You mean from the character creation menu?

[pulsar rock]

Aye

At any point during the game, being able to check "What was this character's starting level"

[thin hornet]

Well you could save a player moddata the first time the character has spawned

[pulsar rock]

Hm, preferably a more dynamic solution

[thin hornet]

what do you mean

[pulsar rock]

Like, one that works even if the mod is added mid-playthrough

By calculating what the starting skill level is.

[thin hornet]

cant im pretty sure

[pulsar rock]

Couldn't you check what the traits add on character creation?

[thin hornet]

depend if traits are dynamic

[pulsar rock]

Oh?

[thin hornet]

and for example obese

would change if player loses weight

[pulsar rock]

I'm excluding fitness and the like

Only "technical" skills

[thin hornet]

but again, what if he gained a technical trait midgame

i mean adding mods midgame you cant expect it to be perfect

People will die and start a new character, unless the server is set to easy

[pulsar rock]

They're generally not gaining traits, afaik?

[thin hornet]

depend if dynamic traits mods is installed

[pulsar rock]

Unless they're using dynamic traits; But I'd say that's a fair enough interaction.

[thin hornet]

its a pretty popular mod

[pulsar rock]

Gain the trait, your max skill level goes up.

Works for me

[thin hornet]

and yeah depending what you want to do why not

[pulsar rock]

¯_(ツ)_/¯

So, how would you fetch what perk points a trait adds?

[thin hornet]

traits stuff is set in lua\shared\NPCs\MainCreationMethods.lua

local function getTraitPerkLevels(traitName)
    local traitLevels = {};
    local trait = TraitFactory.getTrait(traitName);
    local map = trait:getXPBoostMap();
    if map then
        local mapTable = transformIntoKahluaTable(map)
        for perk, level in pairs(mapTable) do
            traitLevels[perk] = (traitLevels[perk] or 0) + level:intValue()
        end
    end
    return traitLevels;
end

[pulsar rock]

I see

getXPBoostMap is what I want, I believe

[thin hornet]

yeah

i checked the \lua\client\OptionScreens\CharacterCreationProfession.lua for reference

get your text editor find tools ready

you gonna have lot of research to do 😛

[pulsar rock]

@thin hornet setPerkLevelDebug just sets the perk level, right?

Also, how would I go about logging something to the console? How about a server's console?

[thin hornet]

 
print("my message");

[pulsar rock]

Right, but does that log properly to a server's debug.log?

Or do I grab a Logger object from somewhere and write through that?

[thin hornet]

well it take a string

[pulsar rock]

Right, I'm wondering what to call to log to the game's logfile, though.

ZLogger:write(...)?

Or writeLog?

[jaunty marten]

DebugLog.log(DebugType, "blablabla")

debug types u can find on pz javadoc

[pulsar rock]

👌

Much appreciated

[jaunty marten]

[pulsar rock]

DebugLog:log(DebugType.Mod, "Debug message here")

Like this?

[jagged ingot]

Apparently you can write TypeScript PZ mods now.

[pulsar rock]

Oh?

[jagged ingot]

This was recently posted to Steam guides: https://steamcommunity.com/sharedfiles/filedetails/?id=2832871498

[pulsar rock]

So

I wrote my mod

Do I just toss it into the mod folder and load it up?

[jaunty marten]

not like method

[pulsar rock]

?

[jaunty marten]

DebugLog:log > DebugLog.log

[jagged ingot]

Static function call, not an instanced method call.

[pulsar rock]

Like this, you mean?

DebugLog.log(DebugType.Mod, "message goes here")

That seems to expect the first argument to be a self, though.

[jagged ingot]

      /**
       * @noSelf
       *
       * Method Parameters: 
       *  - (String arg0): void
       *  - (Object arg0): void
       *  - (DebugType arg0, String arg1): void
       */
      static log(arg0: any, arg1?: string): void;

Pretty cool that I can look this up using the typings from that project I linked.

[jaunty marten]

nope

[jaunty marten]

right

[pulsar rock]

IDE seems to imply it expects it to be

[jaunty marten]

[pulsar rock]

---@public
---@param str String
---@return void
---@overload fun(o:Object)
---@overload fun(type:DebugType, str:String)
function DebugLog:log(str) end

---@public
---@param o Object
---@return void
function DebugLog:log(o) end

---@public
---@param type DebugType
---@param str String
---@return void
function DebugLog:log(type, str) end

This is what I'm getting from DebugLog.lua

[jagged ingot]

Heh. That sortof looks like typings for Lua.

[pulsar rock]

Ngl, first time I'm properly working with LUA

[thin hornet]

Its annotation

[pulsar rock]

So, some of this feels a bit wack

[jagged ingot]

No I know what LuaDocs is.

It's empty functions that made me think that lol

[pulsar rock]

Yeah, they're just annotations for type hinting

@thin hornet You got a clue here?

[thin hornet]

What do you want to do?

[pulsar rock]

DebugLog:log(DebugType:Mod, "SkillLimiter.LimitSkill: " .. character.getFullName() .. " | " .. perk.getName() .. " | " .. level .. " / " .. max_skill)

Really just log to the debug log

I'm just not quite sure whether or not I'm calling the log function correctly

And whether or not the DebugType is passed properly

I'm not 100% on the whole . vs : thing in LUA

Like, I've used C++ / C#, so I'm assuming it's comparable to :: there

Like a static call of some kind rather than to an instantiated object?

[thin hornet]

is DebugLog a new feature?

i always used print()

[jaunty marten]

чел ты.. (maaaan..)

I said DebugLog.log

why are u using method

btw how do u even compile the file with DebugType:Mod

[pulsar rock]

Because my IDE, and the doc, seem to imply that would cause the first argument to expect an instantiated object.

[jaunty marten]

wtf is this

[pulsar rock]

Also, mind just replying in English?

[jaunty marten]

will try

forgot to change lang on keyboard

[jaunty marten]

do you obey to computer?

[pulsar rock]

This is what I'm referring to

[pulsar rock]

If the IDE generally catches mistakes a lot sooner than humans do, I'm inclined to at least give its suggestions thought.

[jaunty marten]

[pulsar rock]

Alrighty then

[jaunty marten]

if ur ide says DebugType:Mod variable is correct then I'm done

[pulsar rock]

It doesn't seem to accept either DebugLog.Log nor :Log tbh

[jagged ingot]

So PZ has a DebugLog in their Lua too?

[worldly olive]

I'm interested in this (just read it the latest comment). So is it possible to debug and print things to the console without using the print? 😂

[jagged ingot]

Weird to have two.

[pulsar rock]

It seems like it's exposed to Lua at least

[jagged ingot]

It is. I showed the typings earlier.

[pulsar rock]

Not entirely sure if I need to instantiate something first though

[jaunty marten]

right but what's sense of it?

[pulsar rock]

Or if it's just some wacky definition hinting

[jagged ingot]

I didn't think that someone would've made LuaDocs for Java API of the game.

[worldly olive]

Is this the syntax then?

[pulsar rock]

Not the faintest clue

I'm new to Lua

Not new to programming, though.

But I haven't really touched Lua, nor interacted with Java with it before.

So some of the syntax is still a bit peculiar to me.

[jagged ingot]

I think Lua complicates invocations more than it should honestly.

[pulsar rock]

Like, is DebugLog in this case an instance we're accessing? Or just a class definition?

[jagged ingot]

This is why I write in OOP languages.

[pulsar rock]

Same 🙏

[worldly olive]

Yeap, same

[pulsar rock]

But, yeah

So

Is DebugLog an instance? In that case .log makes sense

[jaunty marten]

Monkey's labor (с) Sisyphus

[pulsar rock]

No clue why my IDE is hinting at the first arg being self in that case though.

If it's not an instance, calling it through ":" might make sense?

Headscratcher for sure

[jagged ingot]

Thanks. I guess there's two docs / typings now in the PZ universe.

[jaunty marten]

metatables is enough in lua

[pulsar rock]

Metatables look like pure pain, thank you

[jagged ingot]

Sorry but instance literally means an object instance which means non-static calls use :.

[jaunty marten]

metatables are awesome

[pulsar rock]

I still don't fully grasp what : is in Lua tbh

[jagged ingot]

I was confused initially because of the fact that there're two DebugLogs? Or those docs aren't correctly mapping static calls.

[pulsar rock]

The docs might just not be mapping things correctly, is what might be going on

[jaunty marten]

but if u can't get to use function not like method but just static then yea it's will be really pain

[jagged ingot]

: is literally object.call(self, ..)

[jaunty marten]

[novel mountain]

is there anyway to know which mod is this ? Can't launch server because of this

[pulsar rock]

I see

[jaunty marten]

it's not only lua but most of langs

[pulsar rock]

I've used :: and the likes before

[jaunty marten]

no words about c plus plus plz

I'm crying

[jagged ingot]

All var.func(..) calls are static. Using : is a simplification of passing the object's instance to the function.

[pulsar rock]

I see, thanks. That explains things a fair bit.

[jagged ingot]

It's sort of like what I recall python did with self parameters for pseudo-classes, however my Python days were back in Python 2.

Everything that's in the Lua codebase for PZ are pseudo-classes btw.

[pulsar rock]

Sounds a lot like class methods in Python

[jagged ingot]

Lua literally doesn't know what a class is.

[pulsar rock]

Which hurts

On a lot of levels

:')

[jagged ingot]

Which is why I'm hyped about writing mods in TypeScript now.

[pulsar rock]

I can imagine

[jaunty marten]

metatables is fair close

[pulsar rock]

Not much of a JS/TS person, myself

But it's at least better than Lua

[jagged ingot]

It's useful but will not provide things like what OOP standards provide in most modern languages.

[pulsar rock]

^

[worldly olive]

Is it even possible?

[pulsar rock]

Apparently

[jaunty marten]

for example?

[jagged ingot]

Absolutely. Someone just released a full typescript environment for it and even wrote a guide.

[jaunty marten]

#mod_development message

[pulsar rock]

You should give Python 3 a try sometime. It's really quite fun to work in these days.

[jagged ingot]

I have. I just don't need to use Python anymore. 🙂

[pulsar rock]

Fair fair

[worldly olive]

Well... gotta give it a try 👀

[jagged ingot]

/** @noSelfInFile */
import * as Events from 'ZomboidEvents';
import { getPlayer } from 'Zomboid';
Events.onGameStart.addListener(() => {
    print(`Hello, ${getPlayer().getFullName()}!`);
});

[pulsar rock]

But just to get back to my issue:

Simply doing DebugLog.log should work, then? Regardless of the IDE assuming it needs a self argument?

[jaunty marten]

I said twice the final answer to u wtf

[jagged ingot]

You should be fine using DebugLog.log. It's exposed as a public static method.

[pulsar rock]

Mhm, might be an issue with the docs then

[jaunty marten]

[jaunty marten]

@jagged ingot

[jagged ingot]

?

I'm going off of what I know as I've seen the decompiled source code for DebugLog.

[jaunty marten]

for example?

[jagged ingot]

Oh that. Interfaces, Abstract classes, etc.

Lua is as weak with OOP as JavaScript ES5.

[drifting stump]

which can all be accomplished in lua

the difference is lua doesnt hold hands

[jagged ingot]

Which is why I don't like using Lua ultimately.

It's a fun language.

It's great for scripting and works well in a lot of ways. This one is the one I like to focus on for my personal work though so that's why I have a less than stellar opinion of it.

[jaunty marten]

right

[drifting stump]

funny though when you clearly didnt read how that typescript modding framework works

[jagged ingot]

Reinventing those concepts only creates more trouble. With scaling, possible issues only grows.

[drifting stump]

it uses typescript to lua

which inherently means anything that can be done in ts can be done in lua

[jaunty marten]

I had same question

[jagged ingot]

I know it does. I don't think you are reading what I'm actually trying to say.

[jaunty marten]

XD

[drifting stump]

its literally just an abstraction to hold peoples hands

[jaunty marten]

туда его

[jagged ingot]

You're forgetting the compilation process which gives actual errors for support for development.

Selling the idea short.

[drifting stump]

and tbh fine by me if it will improve the quality of mods code

[jagged ingot]

That's the point. 🙂

[jaunty marten]

u need to compile file to get errors instead just press Reload button?

hmmm

yea

it's faster

u even can install lua-linter to catch errors in real time

wtf

[jagged ingot]

Well if you use something like Visual Studio Code, those errors are provided in a panel and auto-refreshed.

[jagged ingot]

Wouldn't that be syntax only?

[jaunty marten]

which errors do u get after compile the file?

not only syntax?

[jagged ingot]

Yes. You see type errors. You see problems when accidently referring to a wrong type or a class declaration doesn't have a method.

[drifting stump]

i am however a firm believer in what a wise man once said

safety checks are useful to prevent crashes but if you just program well you don't need to prevent crashes

[jagged ingot]

You see a lot more.

[jagged ingot]

I think it's a personal decision but foolish to tell to new programmers.

[jaunty marten]

if it runs unit-test on each of my funcs then I going to use typescript

[jaunty marten]

I'm not sure but think linters can do same thing

I'm used linter only once just to test it

[jagged ingot]

Unless you have a very smart linter for Lua that analyzes more than tokens then I don't expect it to look that deep into my Lua code.

[jaunty marten]

just don't code with closed eyes

[drifting stump]

it really doesnt matter most of the issues will be prevented by not letting you do something wrong in the first place or having way better code than most mods

[jaunty marten]

anyway it's not really useful

[jagged ingot]

I think it can be when you import a lot of Lua code you don't know for sure will be syntactically correct.

I use JSON linters when writing my own quick export code.

[jaunty marten]

syntax errors shows in console as I said so useless

[jagged ingot]

Type safety is good for what it needs to be. If you write something small, you likely won't need it.

I'm content to know I have more options now.

[jaunty marten]

btw I want to see how u will create mods on typescripts without auto-refresh in pz

I mean

it's really pain in da ass

XD

[jagged ingot]

Lua files are exported so it would just pick up the file change?

[jaunty marten]

so I need to compile the file each time?

[jagged ingot]

The project I read has a compiler watcher built in.

[drifting stump]

reloading files is a lie it shouldnt be done

[jaunty marten]

it's yes or no

[jagged ingot]

It's a yes if you want to be techincal. It's a no if you're asking if you have to run a command everytime you change your code.

File watchers are a common thing to use for NodeJS environments.

[jaunty marten]

?

so if I change the line in ts file it will pull changes in lua file without compile? wut?

[drifting stump]

detects source changed > compiles to lua

[jagged ingot]

This.

[jaunty marten]

so answer is yes

thanks but anyway useless

[jagged ingot]

If you want to be a dick, feel free. I'm not going to reply to you anymore though.

[jaunty marten]

XD

k

lmao

and etc

[drifting stump]

@jaunty marten do you have your mods on a repo or can link me one

[jaunty marten]

have but restricted

server addons

what's u want?

[drifting stump]

can i look at the source?

[jaunty marten]

there're used global table not modules so better to u don't look XD

[drifting stump]

yeah so point i wanted to make is valid youd benefit from that typescript thingy simply because it would produce better quality code

[drifting stump]

delta really has a point in this

[jaunty marten]

I'm not sure exactly for me cos doing code on lua already for 5-6 years

[drifting stump]

using globals tho

[jaunty marten]

it's not so reduce performance and it's a bit annoying (I mean doing modules) so

the most important to optimise the calls of it

I have it so it's fine

I think

I can send my current mod after I finish it to u check the code if u want

[tired phoenix]

hello guys

do you know any tutorials that could help me implement beards into the game?

i mean

add hairstyles

[round stump]

Hey guys,
if you are looking to make a mod and don't fancy dealing with Lua, maybe consider giving a try to do it in Typescript instead.
There is this project that provides all the Pros of Typescript with all the compatibility of Lua.
https://steamcommunity.com/sharedfiles/filedetails/?id=2832871498

[jaunty marten]

btw I just got that if u can't do good code on lua then u will won't do good code on ts then how it can help? xd

[pulsar rock]

I can write solid code in C/++/# and Python. I'm new to Lua and my code most definitely isn't the best it can be. Some people might have more experience with TS.

Seems reasonable to assume they'll have a much better time (and better quality code) working in TS.

In any case, more options is always a good thing.

[jaunty marten]

I mean if u beginner

[jaunty marten]

yea

[pulsar rock]

You don't have to be an ass about everything, you know.

[pulsar rock]

And aye! We saw / discussed that earlier. It's pretty cool.

[jaunty marten]

he-he

[dapper vector]

Is there an OnReplace function when you eat an item?

[shadow geyser]

if I remember correcty, ReplaceOnUse is the one you want.

[atomic kiln]

Could anyone help me with getting started modding? I'm aiming to add a powered appliance but I can't find anything relating to power use in the game files

[shadow geyser]

yeah if you look at the cannedCarrotsOpen, it has replaceOneUse = TinCanEmpty

[atomic kiln]

I've looked through the wiki modding page and through similar mod files. Do I need to be working in LUA or Java to make a powered item?

[drifting stump]

forces parameter types and abstracts a lot of stuff

[pulsar rock]

How does one get a character's profession?

Found it

[round stump]

Typescript is a strictly typed language, will tell you are are screwing up before you even test it in game.

[pulsar rock]

Hm, how do you iterate over a TraitCollection?

Doing a pairs/ipairs doesn't seem to work?

[midnight mica]

anyone know where i can find all vehicle and vehicle part functions? there doesn't seem to be a vehicle class on https://projectzomboid.com/modding/allclasses-noframe.html

[jagged ingot]

If that's the official JavaDocs, those are as old as 2015.

[round stump]

TIS hasn't updated the JavaDocs in ages

[jagged ingot]

This is the best I can offer: https://github.com/asledgehammer/PipeWrenchTemplate/blob/master/typings/ProjectZomboid/41.71/Zomboid_41.71__zombie_vehicles.d.ts

[midnight mica]

thanks, i'll check it out

[pulsar rock]

@jagged ingot You got a clue as to why this piece of code would throw a MethodArguments.assertValid?

local trait = TraitFactory:getTrait(trait_str)

trait_str is the correct string

[jagged ingot]

I'll look.

[pulsar rock]

Not sure if I'm once again misusing :

[jagged ingot]

/**
       * @noSelf
       *
       * Method Parameters: 
       *  - (String arg0): zombie.characters.traits.TraitFactory$Trait
       */
      static getTrait(arg0: string): zombie.characters.traits.TraitFactory$Trait;
      /**
       * @noSelf
       *
       * Method Parameters: 
       *  - (Empty): java.util.ArrayList<zombie.characters.traits.TraitFactory$Trait>
       */
      static getTraits(): java.util.ArrayList<zombie.characters.traits.TraitFactory$Trait>;

[pulsar rock]

Aye, it takes a string

[jagged ingot]

It's static.

Try using TraitFactory.getTrait(..).

[pulsar rock]

Will do

That did it, thanks!

[jagged ingot]

Glad I can help. You can use a folder-search tool in say an IDE with the typings in that project. That might help.

[pulsar rock]

I'm still low key confused as to why local vars and whatnot use : to invoke their methods, and . seems to be used for static things

[jagged ingot]

It's a combination of two things: The Lua engine being used and Lua code itself.

[pulsar rock]

Is this just a Lua thing?

It's super confusing, ngl

[jagged ingot]

Believe it or not, the Lua engine used by PZ isn't actually Lua. It's a reverse-engineered copy.

[pulsar rock]

Kahlua, right?

[jagged ingot]

Kahlua2.

[pulsar rock]

It's ridiculously weird to do it like that, coming from other languages

But ah well

[jagged ingot]

So, calling new is different from Java objects and Lua objects. You have to use .new(..) with Java and :new(..) for PZ's Lua objects.

: is calling to an instanced object. . is calling to a property.

[pulsar rock]

I see, yeah, that just feels wrong

Ah well

[jagged ingot]

Anything you know that has to involve calling . or :new(..) needs to use : for methods that aren't static.

I agree, however this is how that works.

[pulsar rock]

Thanks for the info

[jagged ingot]

The problem with Java objects is that you don't get to know what is or isn't static by default.

[jagged ingot]

No problem.

[pulsar rock]

Alrighty

Nearly done with the Skill Limiter mod

Just gotta fix 1 more error 🙏

[jagged ingot]

I'm working on a mod that involves modding the core of the game to add support for manipulating music and shaders.

[pulsar rock]

Oh?

[jagged ingot]

Yeah. I'm able to manipulate the GLSL shaders with uniform variables. I also push PCM data from music of my own to them causing some cool effects.

Also some stuff with moodles visually affecting the screen.

[pulsar rock]

A bit like that one old mod that did overlays?

Depending on mood / health / etc

[jagged ingot]

That mod uses images via Lua drawn as UI textures.

[pulsar rock]

Same general goal, though?

[jagged ingot]

I'm actually modding and sending info the frag shaders.

[pulsar rock]

Just nicer

[jagged ingot]

It's GPU driven.

It's so much more than that overlay mod.

[pulsar rock]

Nice!

Okay, I feel like this shouldn't be causing issues; But apparently it is.

__add not defined for operands

            for trait_perk, level in pairs(mapTable) do
                if trait_perk:getName() == perk:getName() then
                    trait_perk_level = trait_perk_level + level
                end
            end

The trait_perk_level + level is throwing that error

I print the level and it looks like an integer type

Like

It prints 3

Unless that's a string as integer?

Or am I missing some weird arithmetic / integer wackyness in Lua?

You have a clue? @jagged ingot

local trait_perk_level = 0

This is where that var is created

[jagged ingot]

Hmm

try tonumber(var)

[pulsar rock]

Let's see..

[jagged ingot]

I'm curious if it's a string, or one of the values is nil.

If it prints a numeric character, it can still be a string.

If you're more curious about type identities in Lua, try using type(var), which puts out a string of the type name itself.

[pulsar rock]

The odd thing is that it was refusing to be concatenated to another string

Ah, Lua has a type()?

Nice

[jagged ingot]

Oh wait

print(type("Hello world"))  --> string
    print(type(10.4*3))         --> number
    print(type(print))          --> function
    print(type(type))           --> function
    print(type(true))           --> boolean
    print(type(nil))            --> nil
    print(type(type(X)))        --> string

btw

So Max, you use .. to concat.

[dapper vector]

yes, but I mean if there is a function that is called when an item is replaced by another

[jagged ingot]

It's like PHP.

[pulsar rock]

Aye, that I know

[jagged ingot]

Ok cool just making sure.

[pulsar rock]

(Thanks though)

But yeah

tonumber didn't do it

[atomic kiln]

So this typescript thing, you all seem to be raving about it. Should I be focusing on that over the traditional way?

[pulsar rock]

Time to print a type()

[jagged ingot]

Whenever you see an error like that, assume first a variable is invalid at this point in the code. Work from the spot that errors going backwards.

[pulsar rock]

I miss debugging in other languages, ngl

I might just switch over to TS for future mods

[jagged ingot]

My bias is clear in the chat history however having type safety and exposed API when writing code will help you so much either being new to coding or not.

[pulsar rock]

And yeah, I do have a formal education and work experience with programming / software engineering. Just... not Lua

[jagged ingot]

It's ultimately an option and yours to make. Not negative either way.

[jagged ingot]

Thanks for clarifying. I do too. I try to make things make sense for those who don't.

[pulsar rock]

That's honestly really nice

And you do a great job at it

Very clear stuff 👌

[jagged ingot]

Thanks. Glad to hear.

BTW the typings alone in that TypeScript environment can act as an additional JavaDocs.

Take a search tool to it when you have questions. It exposes all public functions that the game does for Lua users.

[pulsar rock]

I'm using IntelliJ atm

[pulsar rock]

It's doing a nice job in general of showcasing that stuff

Just apparently not for the static things

[atomic kiln]

So just due to it being easily searchable it'll be easier to learn?

[jagged ingot]

I could go into detail if you'd like. I also don't want to overload the channel about it haha

[atomic kiln]

I humbly request details

You're free to rant

[pulsar rock]

Could do a quick thread?

Though the information seems universally useful for anyone interested in modding

¯_(ツ)_/¯

[jagged ingot]

Sure.

It'll show you errors in many more ways than you can with most Lua writing software. You will see what you're working with and not assume it is a number or a string, object, etc. You have instant access to TypeScript tools like interfaces and abstract classes.

You can see what objects contain.

[atomic kiln]

And here I was just planning to write my lua in notepad

[jagged ingot]

Visual Studio Code is free.

There's also rich text editors like Sublime Text and Notepad++.

[pulsar rock]

I genuinely do not understand people that proclaim writing code in generic text editors is somehow a better experience than IDEs

[atomic kiln]

Don't expect me to know about that. I'm a spaghetti coder, pure and simple.

And yeah, ++ was what I meant

[jagged ingot]

It's mental gymnastics applied to elitism over un-tech-savy people.

[pulsar rock]

Right?

I'm not missing something?

[jagged ingot]

I genuinely hate people who punch down.

[pulsar rock]

It just feels like people trying to prove something or gatekeep IDEs as something bad

Like, holy crap

We made IDEs and other tools to make programming more enjoyable and productive :')

[jagged ingot]

Incompetence, Insecurity, unable to move, explore, learn, compromise, give.

[atomic kiln]

I've just never had a need to learn IDEs because the caveman method works well enough

[pulsar rock]

Oh

More power to you if you personally enjoy / are okay with using regular text editors

[jagged ingot]

You using it doesn't mean I hate you btw.

[pulsar rock]

We're just talking about the kind of people that feel the need to hate on IDEs / people that use IDEs / people that don't want to use regular text editors

On a side note

I found the issue

[jagged ingot]

It's for people who try to act as if IDEs are a sin against their God.

[pulsar rock]

The number is apparently Userdata

That's Java data, right?

Now, how do I convert that

[jagged ingot]

Yes. How do you get it?

[atomic kiln]

You're free to despise my uncultured existence

[jagged ingot]

I can make it easy for you to get it.

[pulsar rock]

From a hashmap, from a trait's XP map

I have the userdata in a variable

Just gotta convert it

[jagged ingot]

Show me the line.

[pulsar rock]

        local mapTable = transformIntoKahluaTable(profession_xp_boost_map)
        for prof_perk, level in pairs(mapTable) do
            if prof_perk:getName() == perk:getName() then
                print("SkillLimiter - Types of level & trait_perk_level below:")
                print(type(level))
                print(type(trait_perk_level))
                trait_perk_level = trait_perk_level + level

[atomic kiln]

I tried out IntelliJ for a bit and was totally lost on how to set up the environment
TypeScript any simpler?#

[jagged ingot]

TypeScript is a language. Visual Studio Code however is way simpler.

https://code.visualstudio.com/

[pulsar rock]

(Jetbrains IDE's are fabulous once you get used to them, though)

[jagged ingot]

They have fernflower, which makes me giddy everytime remember that.

So trait_perk_level

[pulsar rock]

Nay

That's a var I make myself

Initialised as 0

"level" is the issue

[jagged ingot]

Ah ok

If you use `, you can highlight your text better.

[pulsar rock]

I'm aware

[jagged ingot]

Hahah sorry again.

[pulsar rock]

Just figured 0 wasn't necessary :P

[jagged ingot]

Typed a lot of md lately so brain is in that place.

[pulsar rock]

I feel ya

I do a fair bit of Discord server management stuff, with a good amount of markdown text blocks to spice things up 🙏

But yeah

level

From userdata to a generic number / integer

[jagged ingot]

I don't know where this comes from: ```lua
local mapTable = transformIntoKahluaTable(profession_xp_boost_map)

Looking for the Java API call.

[pulsar rock]

Someone tossed me a code snippet & source file to check out

The method they referred me to used that

[jagged ingot]

function dump(o)
   if type(o) == 'table' then
      local s = '{ '
      for k,v in pairs(o) do
         if type(k) ~= 'number' then k = '"'..k..'"' end
         s = s .. '['..k..'] = ' .. dump(v) .. ','
      end
      return s .. '} '
   else
      return tostring(o)
   end
end

Dumps a table and prints it.

Could investigate the table

[pulsar rock]

\lua\client\OptionScreens\CharacterCreationProfession.lua

[jagged ingot]

I have that file open now.

[pulsar rock]

Taken from there

[jagged ingot]

Ah ok

[pulsar rock]

Oh

Found it

level:intValue()

Apparently this works

[jagged ingot]

Epic.

[pulsar rock]

Let's see if the mod works now

[atomic kiln]

This IDE confuses me. I just wanna bash rocks together and make code.
Do I need to install the JS/TS Nightly?

[jagged ingot]

Wait what?

[pulsar rock]

Say, does Lua have something akin to default values for parameters?

[jagged ingot]

Visual Studio Code is a self-updating text editor.

[jagged ingot]

No since types aren't required.

[pulsar rock]

Ah, hm

[jagged ingot]

It'll be nil by default.

[pulsar rock]

Oh

So you can leave an argument open and it'll be nil?

[jagged ingot]

What are you trying to write?

What's the statement?

[pulsar rock]

Just wanted to add a bonus parameter in my function

But I got it, I think

[jagged ingot]

You can write tuples btw

[pulsar rock]

Can you check for nil through if var then?

Like, nil is evaluated as false?

[jagged ingot]

I don't think implicit nil checks as booleans works in Lua but I think it might.

write it in the debug console in-game if open.

[pulsar rock]

Let's see if the mod works now

[jagged ingot]

I know explicit literal checks don't work in Lua.

AKA null !== undefined in JS.

[quasi geode]

nil is false

esentially

if nil then
   -- never triggers
end

[jagged ingot]

Good to know. Thanks. Been writing == nil.

I think a small project I might work on next is a self-documentation tool so I can write documentation for things like the Java API for PZ and have it insert into say those typings or decompiled Java code.

Another idea is to write a simple UI program that templates and has GUI to build custom ISUI Lua classes.

[pulsar rock]

@jagged ingot Mod is alive 🙏

Now, anyone know how to upload a mod to the Workshop?

[jagged ingot]

Yes. Check out ModTemplate in ../Zomboid/Workshop/.

[pulsar rock]

Will do

[jagged ingot]

You toss your mod into the ../mods/ folder in that.

Launch steam-enabled PZ, go to workshop tab, and follow what it says.

BTW you should copy the ModTemplate folder and customize it ofc.

[jaunty marten]

more clear

local strrepeat, pairs, type, format, tostring, print = string.rep, pairs, type, string.format, tostring, print

local function toPlain(tbl, indent, out)
    local isend = not out
    out = out or "{\n"

    indent = indent or 1
    for k, v in pairs(tbl) do
        local tabs = strrepeat("     ", indent)
        formatting = tabs .. tostring(k) .."  =  "
        if type(v) == "table" then
            out = out .. formatting .."{\n"
            out = out .. toPlain(v, indent + 1, "")
            out = out .. tabs .."},\n"
        else
            out = out .. formatting .. (type(v) == "string" and format("%q", v) or tostring(v)) ..",\n"    
        end
    end
    if isend then out = out .."}\n" end

    return out

https://zomboid-javadoc.com/41.65/zombie/vehicles/VehiclePart.html

[wet dune]

@willow estuary How would I just have a single outfit for every zombie?

[bitter hedge]

anyone know where i can find the file to make a custom spawnpoint for single player

[median lagoon]

Hello im starting into moding. What i shuld know or have as begginer?

[atomic kiln]

So when TS for PZ says to install NPM in main folder, does it mean the VSCode folder? Or my project folder?

[jagged ingot]

npm install is a command to run.

So in the project's folder, run it.

It sets up all the dependencies and plugins in the environment that run when compiling the code.

It's a NodeJs environment and npm is the "Node Package Manager".

[jagged ingot]

This is a console command. Forgot to clarify.

[midnight mica]

anyone have any idea why setContainerCapacity does not seem to work server side?
it works whenever i use it when the vehicle is created, but once its created i can't change the container size anymore, seems weird

[static oyster]

anyone knows the line of code that tells if the zombie can see the player or not ?

[thin hornet]

So I have reworked the base mod repo im working on.
https://github.com/Konijima/Project-Zomboid-BaseMod-Concept
It can be used as a template for lua mods and or just for maybe learning something

Ill try to make a tutorial how it can be extended and used

but basically i might be using this for all my future mods so I ll keep it up to date too but also minimalistic

[drifting ore]

how do i override

a modded item?

[drifting ore]

If i dont use item tweaker

[prisma wren]

hey can someone help me figure out how to make a VHS + book mod

im a complete beginner in JS

and i’ve never done any modding

[jagged ingot]

JavaScript?

[prisma wren]

yeah

[jagged ingot]

PZ uses Lua. I bet you already know this.

Are you familiar with Lua's syntax?

[prisma wren]

forgot

a bit

[frosty falcon]

break it down to smaller tasks and work on those

[jagged ingot]

I'm sure that the mod would be simple enough to use Lua by itself, however if you know anything about TypeScript and feel more familiar with JavaScript, you have the option to use TypeScript.

I think the majority of your mod would be item scripts.

[jagged ingot]

Absolutely good general advice.

[frosty falcon]

lots of small victories > one large project challenge for newer ppl imo

[jagged ingot]

Isn't there a guide somewhere that's generally used for types of mods for items for PZ?

I remember some website that had a lot of tutorials.

[frosty falcon]

so depending on what you're doing with the book for example, you could finish that part first make sure it's all working and try the next bit

I say this because you can lose motivation if you get stuck on a big project, that said yours seems fairly straightforwad, good to begin with

[prisma wren]

i know that part from developing stuff

[frosty falcon]

decide what you're gonna do first, try it, come back if you get stuck

[prisma wren]

alright i’ll do that

[frosty falcon]

sounds good, lots of helpful people in here :)

[jagged ingot]

If you have any issues with Lua and can't find answers after looking it up on Google, it isn't a sin to ask here.

[frosty falcon]

I mainly learned from picking apart other peoples basic mods when I started

didn't quite find any solid tutorials if I'm honest

[jagged ingot]

I learn from breaking and reverse engineering hahaha

[frosty falcon]

learning you can use java too was super handy

the public classes

[jagged ingot]

Yeah. 95+% of my modding in PZ is Java.

Oh, and Kotlin.

[frosty falcon]

I haven't actually checked whats exactly exposed to kahlua, but seems a good majority or all of the public java classes are availabl

[jagged ingot]

JavaDocs are good (The 3rd party ones). I would recommend this to people who want basic, traditional documentation. I also use an alternative typings set for TypeScript interpretations. 🙂

The latest JavaDocs rendering is 41.65 though. With 42 on the horizon, this could be problematic.

[frosty falcon]

ye I mean this stuff

I think its just a selected set of exposed classes

[jagged ingot]

I don't know the TOS here however decompiled code is a gray zone so just a heads up.

[frosty falcon]

ye its fine

[jagged ingot]

Those items are recursively exposed.

The typings I'm referring to only shows what Kahlua2 exposes through PZ.

JavaDocs like the ones I know shows more than what's exposed. This could be confusing to someone who tries to invoke unexposed content.

[frosty falcon]

thats what I'm trying to understand, which parts of the javadoc is unexposed

not exposed

[jagged ingot]

https://zomboid-javadoc.com/41.65/zombie/network/GameServer.html

I can see this being confusing for people who don't understand.

[frosty falcon]

is it simply all public java classes

that I can view in the decompiled code

[jagged ingot]

My experience helps me know what is and isn't.

[frosty falcon]

or did this javadoc come from a generated subset of classes

only answer I suppose is to try

[jagged ingot]

This one specifically comes from third-party. It means that the code from the game was ran through a JavaDocs tool.

[frosty falcon]

yea dw

[jagged ingot]

Same with the official one from 2015.

[frosty falcon]

was just confusing myself a lil

[jagged ingot]

If you want to see what 41.71 exposes, check this out: https://github.com/asledgehammer/PipeWrenchTemplate/tree/master/typings/ProjectZomboid/41.71

Items that are type are exposed but not directly.

[frosty falcon]

oh this is quite nice and organised

[jagged ingot]

From what I can see, the typings were generated where classes in the zombie package are recursively unzipped and compiled so I can still see some classes here that might show things that aren't accessible. It is based on that codeblock you see in LuaManager.

It'll be closer to what you'd expect to see exposed.

Even then you'll see where that call ends up.

[frosty falcon]

gotcha

[jagged ingot]

Seeing the actual types for parameters, return types, and static fields helps though.

JavaDocs has that too.

[frosty falcon]

yea haven't used much of java so far but theres a lot of useful things in there

often you don't need a lot of it tbh

unless you're going real deep with your mods

[jagged ingot]

This is why I'd need this mapping more than JavaDocs.

🙂

[frosty falcon]

its pretty nice being able to make an entire bicycle mod without even referring to javadocs

[jagged ingot]

The biggest thing missing from all documentation is.. documentation. 😛

[cosmic condor]

none of my mods is java lol

[frosty falcon]

I'm curious why its different to the decompiled code, what exactly is the typings you have

[jagged ingot]

The comment on the bottom is for the next one below it.

[frosty falcon]

ohh ok I misread it

[jagged ingot]

It's TypeScript so method signatures differ from say Java where multiple methods with non-erasure parameters can be a thing.

They have to be combined to follow the TS syntax.

[frosty falcon]

oh you're using it for typescript

that makes sense now

[jagged ingot]

It's actual typescript.

[frosty falcon]

yeye

[jagged ingot]

That GitHub project is actually a TypeScript environment to mod PZ using it.

[frosty falcon]

I thought you were telling me you used it instead of java, but without the context of typescript xd

was like, wat the

but it makes sense, this is just directly matching the java... can't think of the right words rn ugh

binding them

now the question is

will this project be maintained

but in the dev world, I guess that's always the question

[jagged ingot]

Yes. This project was said to have taken 6 months to make. I don't think it'll be abandoned soon.

[frosty falcon]

could be

[jagged ingot]

Well I know the author.

[frosty falcon]

curious if someone else would take the mantle
