mod_development

[small topaz]

Yes. I put my script.txt folder in the common folder. Then, it doesn't work for my B41 version of the mod but it does work for the B42 version. (Both version don't contain the script.txt in there media folder ofc.)

[bronze yoke]

it's not supposed to

build 41 does not load files from build 42

the common folder is a new feature so older versions don't support it

[small topaz]

Ok. Many thanks for the info.

But what exactly are then the supposed files which may go into the common folder if it only works for one version? Is this just a tool for future versions (or maybe even different patched version of B42)?

[umbral raptor]

is there a tag or flag for recipes that allows crafting while an item of a recipe is on the ground?

[bronze yoke]

yes

it'll make more sense when multiplayer comes out and people will actually stay on older versions, and when b43 comes out

[bright fog]

bruh

[bronze yoke]

for now i recommend putting all assets into common, and all code into 42

translations can also be in common

[umbral raptor]

or you can do the big brain thing and place all your files in both

https://tenor.com/view/brain-brain-meme-big-brain-big-brain-meme-big-brain-time-gif-2441110471562975014

works for me

takes up more space but wont matter for tiny mods, only matters for large ones

i just copy and paste my media files in both 42 and common

[bronze yoke]

why would you do that ???

you can just leave one empty if you really don't want to engage with it 😭

[small topaz]

I still don't understand: which parts of the mod can access the files from common? If it is only B42, then I still do not get how you can save space by putting data to the common folder because having the data in common or in B42 doesn't matter then (takes up the same amount of space).

[bronze yoke]

right now it doesn't really matter

it will matter more in the future, when b43 is out, or when there are multiple patches people are playing, and your mod may need a different version for each (this will definitely start happening when multiplayer is out and servers don't want to break their saves)

[small topaz]

ok! then I understand! thanks for explaining!

[torn igloo]

ELI5: What does setAnchorLeft / setAnchorRight / setAnchorTop / setAnchorBottom do?

[bronze yoke]

when the parent panel is resized, it will follow the edges it's anchored to

if it's anchored to two edges on the same axis, it will resize itself so that the distance between the edges stays the same as it was before

[abstract iron]

So i was thinking about something, what do you guys think that is the most fundamental coding/scripting consepts are in the creation of mods for pz, for instance I suspect that object oriented coding/scripting is a huge part of pzs system.

What are your guyses thoughts on this

[bright fog]

Actually, object oriented coding is not that much used in the lua

It's used for timed actions, context menu, UI related elements

But I didn't need to touch any of it for a while tbf

And it's fairly easy to play with

[abstract iron]

I see,

So potentially arays or data structure?

[bright fog]

Tbf it really depends

It depends what type of mods you do

There's no specific requirements

[abstract iron]

That makes sense, I think in order to pin point it one has to understand what they are doing before they understand what fundamental is required

I'm writing a paper and so these are just some questions I intend to answer in a digestible way

[bright fog]

A paper ?

[umbral raptor]

is the the recipe tag InHandCraft neccessary for the recipe to work?

i see it in pretty much all recipes

and i wanna make one where the items are on the ground

[bronze yoke]

most modders are completely new to programming so they aren't really familiar with specific programming paradigms or patterns

the more experienced modders, especially with previous experience in computer science, do tend to use OOP, but i'd say the average mod doesn't use it at all

[mortal escarp]

Was just about to ask for link, you are awesome bro, thanks @bright fog

[small topaz]

As a general question: do you think it is a good idea to add your code to a lua event and also to manually trigger lua events? Or has this a significant likelihood to cause stability issues?

[bright fog]

Depends

As long as you don't trigger the event during the event

Or that's called a while loop lol

[silent zealot]

Which lua event(s) are you think of triggering manually?

You may also want a safeguard of some sort to stop recursive/unwanted event triggering.

[bright fog]

Like I said, don't trigger the function which triggers the event

[small topaz]

Maybe better an infinite loop. 😉 But no... that's nothing I am going to do.

[small topaz]

in my case, it is the OnClothingUpdated event but my question was more general about using events and what other modders think about it from a technical and stability point of view

[slim swan]

Is there any way to teleport the vehicle?

Only find teleport vehicle in bullet,not sure if it would work

[round kiln]

so with item tweaker mod no longer going to work on b42, what is the way to modify the values of existing items
like do i modify the item tweaker code or?

want to make something related to changes of certain values/output something different after using items

[bronze yoke]

local item = ScriptManager.instance:getItem("Base.Apple")
if item then
    item:DoParam("Parameter = Value")
end

this is all item tweaker ever did

[round kiln]

ah i see

its really just that

[abstract iron]

Ok that makes sense

[round kiln]

i find it interesting how this mod that has existed for 10 years now really is just that lol

[abstract iron]

Yeah just related to coding/scripting and how it's applied in the subgroup relm.

[round kiln]

so with this i can go and modify existing parameters, and also add in new ones (possibly from other mods too)

[bronze yoke]

yep

[bronze yoke]

it's so common place nobody thinks to question how it actually works, everyone assumes it's just impossible without it 😅

[small topaz]

Is it possible to change a specific parameter of a specific clothing item's xml file while the game is running via lua coding? Specifically, I want to temporarily delete the xml paramter
<m_UnderlayMasksFolder>media/textures/Clothes/BulletVest/Masks_BulletVest</m_UnderlayMasksFolder>
which can be found for several vanilla clothing items (in my case mainly bullet proof vests).

[umbral raptor]

het i have a very simple lua request from anyone that can help

i want to make an item that can be written on like a notebook but doesnt require a pen or pencil to write on

thats its.

so pretty much skipping the requirement for pen/pencil for a single item

i have no idea how to do it, so if anyone can, let me know

u can help by also telling me where to find the LUA files related to the writing on notebooks system.

[round kiln]

theres a mod that i know that hasnt been updated for almost 3 years now with no updates or interest from the original mod creator and want to port it/expand upon (which uses itemtweaker)

[ancient grail]

yep that mods goal was to make it simple for other modders to change values of items without having to learn lua

tho most of the ones that did use it added shit ton of prints lagging the shit out of servers

[bronze yoke]

it also doesn't even fully work in multiplayer lol

it only changes the items on the client side, which sometimes doesn't matter but sometimes does

also, the prints aren't the fault of the mods using it, item tweaker is the one that does that

[small topaz]

I'd start and check the vanilla code in media/lua/client/ISUI/ISInventoryPaneContextMenu.lua. This generates the right-click options for the items in your inventory. There is also an option for writing in journals, notebooks etc. The option for writing is only present when players have pens in their inventory. So you could pbbly make a writable item and simply don't use any condition stating that there must be a pen available. (Could be difficult coding though...)

After players click the option to write, there is a specific timed action which is triggered (should be ISWriteSomething:new()).

Also possible that there are simpler solutions. It is just my first idea.

[umbral raptor]

thanks alot, will check it out ❤️

[small topaz]

Not 100% sure but aren't there even easy methods to add a right click option to a modded item (using some kind of lua event or smth)? In this case, you could simply try to add a "write" option to your item and then trigger an appropriate TimedAction, similar as the vanilla code does.

[abstract iron]

Are you talking about like, a Minecraft notebook?

Or just a notebook without the required pen/pencil used in the game?

[umbral raptor]

the project zomboid one.

i want to make one that doesnt require a pen or pencil to write in

[abstract iron]

Hmm

[eternal tiger]

Okay so I am just trying to get a custom Map Symbol, but I keep getting stack trace errors on Build 42.

I have a 64x64 PNG stored in common/media/ui/Lootablemaps and my MapSymbolDefinitionsTF.lua is simply MapSymbolDefinitions.getInstance():addTexture("TFSkullBones", "common/media/ui/LootableMaps/map_TFskullbones.png", "Test")

Everytime I open my map with my mod loaded, I get errors and the map refuses to open. am I doing something wrong here?

[eternal tiger]

Hmm. I'm thinking it might be the .png itself causing the problems

[eternal tiger]

Actually it seems you need at least 9 different Map Symbols otherwise it breaks the map 🤔

[eternal tiger]

Hm yeah that seemed to fix my issue.

Just needed to make 8 more symbols

[round kiln]

oh yeah, where do i put this code in the lua folders? client server or shared?

shared

trying to figure out why pz crashes from the existence of my mod being turned on

theres also only very few files in it

[drifting ore]

Did you check console.txt in your user zomboid folder?

[round kiln]

i did but not sure what to look for

[drifting ore]

Usually at the bottom of the console log after a crash, it will show which file was being loaded before everything stopped

[round kiln]

hmmm

[drifting ore]

If you send the console.txt file I can help you take a look

[round kiln]

sure

i should also mention the few files that i have, referencing the file format of how other mods do it

[drifting ore]

It looks like in items_dairy.txt you are referencing "Weight" as an item parameter

Which is not valid for some reason... mind sharing items_dairy.txt?

[round kiln]

ah, i see now

forgot a comma

the classic

thanks for checkin

[drifting ore]

No problem

[round kiln]

but now i gotta try to see if theres any more problems before the repeat the process

[silent zealot]

That's exactly how professional programmers work too - fix a bug that breaks everything, then work on the next bug that breaks everything, and eventually you get to start working on the bugs that don't break everything but cause things to go wrong.

[round kiln]

finally fixed the problem that i was dealing with

time to repeat the process

i had coded before, but never done lua or pz modding before

like sometimes

[brave bone]

question: why do some items have "attachment world" in the model scripts, but i don't see world in the attachment block parameters, does this mean that it can be placed like the workshop mod's workbench? thats the only thing that makes sense that i can think of.

[indigo copper]

Is there a way to know if a zombie is alive when a player attacks it?
I tried using the OnHitZombie event, but the IsoZombie parameter in this event gets the state before being attacked.

[sand saddle]

i have a strange bug in my modlist and for the god of code i cant figure out which mod causes it. so i pondered to go with a Filesearch to figure out wich mods are most likely the culprit. the issue is : if i dismantle a metal floor or metal wall i crafted i get blowtorches back..... so to narrow down what mod/s might be the culprit/s i was pondering to do a "search in files" with notepad++. what functions mess with the return of dismantling?

to note : there is no error associated with it. and the return is "full" blowtorches.

[vague marsh]

check your subscribed mods, youll easily narrow it down there

[winter bolt]

do OnWeaponHitXP and then check iif its an isozombie

that event fires after allll the damage stuff is done

[sand saddle]

i was hoping to scale the amount of mods to check down in figuring out wich mods might touch it. i have like 200 active.

[vague marsh]

yeah you already have a clue "if i dismantle a metal floor or metal wall i crafted i get blowtorches back" so it might be related to mods that does that

[sand saddle]

nope not subvscribed to a mod like that. i only noticed this (i think cross mod bug) in my actual playtrough. once i had learned the recepies and tried to build a base.

[vague marsh]

maybe try to reduce em half by half so you can easily find what mod is causing it

[knotty stone]

anyone know where the function is to destroy plants when you drive over it with a vehicle?

[sand saddle]

you should have a look at https://steamcommunity.com/sharedfiles/filedetails/?id=3413150945 i bet that mod uses that function or a adjacent one.

[knotty stone]

hm ok, thx

[sand saddle]

seems it wasnt a mod. even with all mods disabled it still gives me blowtorches back. i think its that i have welding 10...(trained it up by using a mod to dissasemble cars). b42 by the way. seems i have to live with it.

[silent zealot]

To start: go to C:\Games\Steam\steamapps\workshop\content\108600 (or equivilent folder) and use whatever tool you most like to search for any .lua or .txt containing the word "blowtorch"

Unless you have some super weird mod reverse engineering deconstruction by looking at the inputs to make something, twhatever mod is creating blowtorches needs the text "blowtorch" somewhere in it.

[sand saddle]

i dont think its a mod anymore. i disabled all of them and still get blowtorches back. so i think its a b42 thing....

[silent zealot]

If it happens with no mods, report it on the bug report forums

[vast pier]

You’re making sure to disable the mods on the save file itself, right? Not just in the mod manager?

[sand saddle]

Yes. im currently trying to figure out how to replicate the issue without using debug mode. using those would likely invalidate the report.

training up welding and finding the neccersary magazines is a hassle.

[vast pier]

I don’t think debug mode would be causing recipes to bug out like that

[sand saddle]

my guess is that dissasembling stuff takes the crafting material. does some arbitary math and chances to return items on skill. and maxing out your skills makes it wonky and returns useables in full condition. but yeah currently testing that.

[knotty stone]

how do i disable/kill a vanilla function?

[sand saddle]

you would need to replace it with your own.

[sand saddle]

As a example (fantasy function)

`local old_FunctionForStuff = CategoryForStuff.Functionforstuff
function CategoryForStuff:FunctionForStuff(input A, InputB)

end`

if it has a return value add a "return Thingtoreturn" into that function.

this would disable the function entirely. keep in mind this might have bad consequences if not tought about. any mod that uses that function would be Broken.

ok iam to stupid to get it^^ I need to get rid of the self:destroyOnWalk(luaObject,square) or the if square:isVehicleIntersectingCrops() then luaObject:destroyThis() return end in the second function ```function SFarmingSystem:checkPlantSquare(luaObject)
local square = luaObject:getSquare()
if not square then return end
luaObject.exterior = square:isOutside()
luaObject.hasWeeds = SFarmingSystem:hasWeeds(square)
-- if the plant has enough of a pest flies infestation we apply flies to the square
if luaObject:hasVisibleFlies() then square:setHasFlies(true) end
-- we may destroy our plant if someone walk onto it, or if it's already dead
self:destroyOnWalk(luaObject, square)
end

function SFarmingSystem:destroyOnWalk(luaObject, square)
if square:isVehicleIntersectingCrops() then
luaObject:destroyThis()
return
end
end

[crystal oar]

is it going to be a problem if i use the 41 client to update my mods? i can't get experimental to load at all

[bright fog]

What are you talking about ? Updating your mod to B42 while in B41 ?

B41 can't read B42 mods

[slim swan]

is there any way to teleport the vehicle?

[crystal oar]

i don't really need it to read the b42 mod, i'm just updating the mods for b42

[bright fog]

Are you sure they even work without changing anything ?

[crystal oar]

no, but i'm sure they don't work without updating the folder structure

my mods are mostly single recipes, like turning seeds into oil or something, i'm sure if someone tries it on 42 and it doesn't work they will let me know. right now they just don't work in 42 at all without the update.

[drifting ore]

Hi everyone! I am looking for a lua function that retrieves the debugger's error count. I thought getLuaDebuggerErrorCount (https://zomboid-javadoc.com/41.78/zombie/Lua/LuaManager.GlobalObject.html#getLuaDebuggerErrorCount()) would be the function.

[bright fog]

@sour island might know

[sour island]

Whatever I used for error mag is the list of errors

Some errors are not added though - due to how the exceptions are sent

[steep glade]

I'm new to PZ modding, does anyone knows why I get 30k+ undefined global warnings lol
on my workspace theres only the mod folder and the b42 lua folder

[drifting ore]

are you referring to console.txt?

[sour island]

No, there's a function and array for errors in game.

It's the same method the F11 screen uses

https://github.com/Chuckleberry-Finn/errorMagnifier/blob/main/Contents%2Fmods%2FerrorMagnifier%2F42.0%2Fmedia%2Flua%2Fclient%2FerrorMagnifier_Main.lua

getLuaDebuggerErrors()

[sand saddle]

i would propably overwrite this small function :
function SFarmingSystem:destroyOnWalk(luaObject, square) if square:isVehicleIntersectingCrops() then luaObject:destroyThis() return end end
to replace it you basically overwrite it. place it appropiately into either client/shared or server subfolder.
function SFarmingSystem:destroyOnWalk(luaObject, square) if square:isVehicleIntersectingCrops() then --luaObject:destroyThis() return end return end

[knotty stone]

ok i will try that, thanks for your help

[sand saddle]

eeks. dont copy paste what i wrote i placed a "end" and a return to many into my example.

just copy the orginal function over and comment the destroy line out (--))

[sand saddle]

sorry my mistake

[knotty stone]

i tried someting similar but its just not working, maybe iam somehow at the wrong place there is also this in this function -- the other stuff is handled java-side now, maybe iam just stuck with it, so no Agrotsar welp 😄

[sand saddle]

sorry cant help with java modding. that stuff is a blackbox for me -.-

[drifting ore]

I found this in your file: getLuaDebuggerErrors(). It seems getLuaDebuggerErrors():size() is the count. Thanks!

Ah oops, yeah- sorry should have explained better.

I'm trying to port the ZuperCarts mod to B42 for myself and I have it working without errors, but the animations don't work. Anybody got some idea of what I need to change? It's painful to play this game without the mod and iBrRus doesn't seem to be coming back.

[karmic wedge]

Does the common folder work in B41 or do I need to do this for my mod to still work in 41?

[merry patio]

Yesterday, someone explained to me that you should put the contents of your 'media' folder from version 42.0 into the mod's 'media' folder! That way, it would be compatible with both versions!

[karmic wedge]

So like above image.

unfortunate, doubles file size

[prime viper]

tried making a main menu background mod, but all I get is a black background and 4 errors, any reason as to why this is?

[sand saddle]

i wished they had added a b41 hotfix to load a "41" or the "common" folder to ease backward compatibility. missed opportunity.

[karmic wedge]

yeahg, womp

is there a list somewhere that has all the distribution changes?

[bronze yoke]

your ide doesn't know anything about zomboid's api, so it thinks everything is undefined: install umbrella and most of them will go away https://github.com/asledgehammer/Umbrella

some will remain because the vanilla lua just does things that would be considered bad 😅

[umbral raptor]

u need to put a ; after the item name

in the inputs

and also the outputs dont use a [] betweent he name

heres a recipe as an example

craftRecipe ConvertToFuel
{
Time = 30,
timedAction = Making,
AllowBatchCraft = False,
Tags = InHandCraft;CanBeDoneInDark,
Category = Survivalist,
inputs
{
item 1 [SupportCorps.LanternElectricEmpty;] mode:destroy,
}
outputs
{
item 1 SupportCorps.LanternFuelEmpty,
item 1 Base.LightBulb,
}
}

see how i did it?

[karmic wedge]

Weird, I don't see that in any of the base game files but I'll try it

[drifting ore]

Should just be the output, it works without the ; if you only have one

[umbral raptor]

yeah, what bjorn said. im used to putting it in all my recipes

but if it doesnt work, try adding it.

Hrmm. Still getting TNG_VHS.TNG_VHS_Collection_S5. line: item 1 [TNG_VHS.TNG_VHS_Collection_S5;] spit out at me.

this is what it looks like now

    item TNG_VHS_Collection_S5
    {
        DisplayCategory = Entertainment,
        Weight = 0.1,
        Type = Normal,
        DisplayName = Star Trek: The Next Generation Collection 5,
        Icon = TNG_VHS_Case,
        WorldStaticModel = TNG_VHS_CollectionBox,
        Tags = IsMemento,
    }
    craftRecipe Open Star Trek: The Next Generation VHS Collection 5,
    {
        timedAction = PackingBox_Small,
        Time = 80,
        OnCreate = Recipe.OnCreate.TNGVHSCollectionS5,
        Tags = InHandCraft;Packing;CanBeDoneInDark,
        category = Miscellaneous,
        inputs
        {

        }
        outputs
        {
            item 1 TNG_VHS.TNG_VHS_EmptyCollectionBox,
        }
    }

It just really hates season 5 I guess lol

[bronze yoke]

there shouldn't be a semicolon after the item name

the semicolon is supposed to separate multiple item names

[karmic wedge]

Was just told me to add that a few messages up
Regardless, same error with or without.

[bronze yoke]

is your module definitely named TNG_VHS?

[karmic wedge]

Yep yep
module TNG_VHS;

[bronze yoke]

there shouldn't be a semicolon

your module is called TNG_VHS;

[karmic wedge]

Lua changed in B42? This mod has been working on b41 with that semicolon for nearly a year

[bronze yoke]

this isn't lua, but there may be slight differences in script parsing now

[karmic wedge]

I see, funky

[bronze yoke]

also if your b41 recipes referred to the item by their short types, module name wouldn't matter

[karmic wedge]

Distribution referred to them with the module

it just works ™️
trying without now

[bronze yoke]

huh, maybe it's a parsing difference in b42 or i'm wrong - but in my experience the parser doesn't drop special characters from module names

[storm trench]

Anybody have experience with animations not working when porting from B41 to B42?

[bronze yoke]

you need animsets in the b41 location as well as the b42 location or they won't be loaded

so media/animsets *and* 42/media/animsets or common/media/animsets

[storm trench]

Ahhh that explains it, I think. Thank you so much!!!

Yep, problem solved. 💚

[south bear]

What function sends a client send a message in /all to a MP server?

[karmic wedge]

Yep lol. ; in the module name definitely wasn't helping anything. New useful errors to work with now. Thank you.
Made the naming scheme sane, no more TNG_VHS.TNG_VHS_Collection_S1 Not sure what my thought process was when first making this. Few more things to solve and it's b42 working again yippie

[slim swan]

Anyone know how to get the item’s position

I tried using WorldItem, but if the item is not on the ground, its position cannot be detected.

When the item is in a cabinet or something similar, it can still be recognized as a WorldItem, but when it’s in a car trunk, it’s no longer a WorldItem.

[bright fog]

I believe you can get the container

And from the container you can find where it is

[eternal tiger]

It has begun.

[bright fog]

Custom icons, nice

[eternal tiger]

I wish I could make these with custom colors instead of just the pens. Not sure how one would do that.

Cause right now I use 3 different stamps. The Background, the Hexagon, and finally the Icon

[bright fog]

[eternal tiger]

but I guess that also means you can use any other Icon pack you want and make a little border for it.

[storm trench]

Changing the capacity for the mod doesn't change how much the container holds. Anybody have an idea why? It was 49 by default, but that equaled out to only 37 in game. So I changed it to 75, which adjusted it to 48 in game... until it just... stopped doing so. Now it's back to 37 no matter what I start a new game with the container value set at.

[bronze yoke]

container capacity cannot be higher than 50

[storm trench]

I'll give that a go, but the weight of 37 in-game still had that issue set at the default 49.

[storm trench]

Yeah, don't change anything unfortunately.

"Why would you ever need to put more than 50 arbitrary units of stuff into a container?" - Devs

There are seperate limits in Itemcontainer:

[bronze yoke]

why aren't these static anyway?

if you can convince people to stay in debug mode you can get around it i suppose

i'm pretty sure they're enforced by lua anyway though

there's rarely any reason to but you can set instance field values in debug mode

[silent zealot]

My guess is they are defined in some other file and end up hard-coded into the class after being compiled, but yeah - shoudl be static

[silent zealot]

They 100% are, because I'm working on a lua mod that bypasses every such restriction

Just need to fix a problem where moving a worn container over 50 weight to a different body location will drop it onto the floor AND put it in your inventory.

(which also gave me the idea for an Ender chest mod, where you make a container that access the same inventory from everywhere)

[bronze yoke]

that could be brutal to implement

i suppose you could put an invisible + weightless container in the player's inventory as long as you don't care about other players being able to access it too

[silent zealot]

I thought it wouldn't be too bad, it's not 850 lines of lua patching because weight limites show up in all worts of stupid places

[silent zealot]

It might be possible to store an inventory object per-player then attach the appropriate one when the object is accessed.

[storm trench]

That would be awesome tbh. If doable.

[silent zealot]

Assuming there is some sort of unique id per player, which I assume there is.

[bronze yoke]

the issue is if it's not in a regular container somewhere it won't save

so it has to be in someone's inventory for safety

[silent zealot]

More likely it would need some sort of action to attach the inventory attaching to since accessinga container is a direct java call, so might end up being a "place chest in world to access" type of deal.

[silent zealot]

Could Make a series of boxes somewhere in the wilderness to hold stuff

[bronze yoke]

the squares would have to be loaded for their containers to be accessible

[silent zealot]

hmmm

[bronze yoke]

you could do it if you could serialise inventory items and load them on demand, starlit had a module for that in b41 but i don't really want to update it

[silent zealot]

well, all that is aproblem for a mod I'm not even going to consider starting until I finish up three half-done mods

[bronze yoke]

every time they add some new thing that either needs to be saved or changes how items are saved i'm probably deleting people's items so i'll probably just leave it in b41 which will never change anyway

[silent zealot]

At minimum, wait for B42 stable to do that.

...and then to further make sure I don't get all my half-done mods finished I installed Avowed and it's such a weird game; like Skyrim except it all just works without horrible jank and 50 QoL mods to have a usable inventory interface. And it's Unreal 5, but runs so smooth out of the box without changing any settings on my 4 year old video card.

And it's a AAA RPG, but doesn't feel like it was built by a committee of executives that don't actually play games.

It's just.. fun to play, and I didn;t realize how much I mesed that with new games. Even if it's going to be a one-playthrough game for me, unlike Zomboid and it's thousands of hours.

[plush wraith]

Trying to find a way to detect this event <eventOccurred>collideWithWall</eventOccurred> but not seeing anything I can call. Anyone tinkered with this before?

[bronze yoke]

i think you can only catch these in timed actions

[silent zealot]

Sometimes it's odd what events are missing - like I was just looking for a vehicle damaged event, and the only one is "vehicle damaged enough to need a new texture"

The car dashboard has it's own routine that saves the car state and rechecks it every 10 ticks to see if it got worse.

[plush wraith]

Ya, Im trying to detect different falling/tripping events, falling over a fence sets a flag you can detect from the playerObj, but falling from running into a wall doesn't follow the same logic

PZ devs keeping us on our toes

[bronze yoke]

you might be able to detect the player entering the collidewithwall state?

[plush wraith]

Ya I was looking for something to check collide/collidetype but still looking around

Was also looking at the different bumptype variables that get set at times

Seems like 3 different systems from over the years

[bronze yoke]

in an OnAIStateChange callback you can check if the new state is the collidewithwall state

[eternal tiger]

I have to say, when renaming bulk images windows powershell is a godsent.

This would take hours if this didn't exist. LOL

[drifting ore]

There is a tool I use… bulk renamer or some shit like that

[plush wraith]

this is what I was looking for TY 🙂

[eternal tiger]

I use $counter = 1 Get-ChildItem *.png | ForEach-Object { $newName = "$counter-REPLACEWITHNAME" + $_.Extension Rename-Item $_.FullName -NewName $newName $counter++ }

That way it doesn't have the annoying trailing (#) at the end.

My IT courses finally coming in handy. And its for modding a game. lol

[drifting ore]

Bulk Rename Utility if you wanna check it out… Ive never had that issue with the # trailing but I primarily use it to rename media files

[eternal tiger]

I'll just stick to powershell. It serves its purpose really well.

[silent zealot]

Knowing some basic Powershell (or linux shell) is huge timesaver sometimes.

[eternal tiger]

It really is. I have a Raspberry Pi I use to mess with linux or a virtual machine depending on the day. I'm really debating about switching to a Linux OS for gaming, but a few of the games I play rather often aren't supported.

I have well over 200 files I need to rename in various locations, so this little script is saving me so much time.

[silent zealot]

I love linux, but for gaming stick to Windows.

I will also qualify that with in the last twenty years I've done huge amounts with linux but only ~2 hours of that was using a GUI when a developer needed one for something... everything else has been commandline

[silent zealot]

hahahaha

Nice icon style

...at least you have preview images done

[vast pier]

cough https://game-icons.net cough

[vast pier]

the only one out of these 5 mod images that I've been actively working on is the molotov icon

cuz that's the bomb rework mod

[eternal tiger]

I got my icon done. Just gotta do the preview images.

[vast pier]

nice

[silent zealot]

I used the rimworld font when I uploaed by first steam mod, and then was lazy and re-used it for Zomboid... but it makes for a nice distintive preview image. https://steamcommunity.com/sharedfiles/filedetails/?id=2737639560

[vast pier]

I encourage people to use game-icons.net but I'm worried at some point someone is gonna just fully copy the design style I do (the color choices with the background and border)

It won't be a big deal just kinda bleh

The main reason you can look at a mod and tell it's one I made is because of the background color

[eternal tiger]

That looks awesome. Love the font

[vast pier]

I also try to reuse colors for the same materials as frequently as possible so that everything uses the same color scheme

for consistency sake

[bright fog]

New page about how to modify context menus, add options etc
https://pzwiki.net/wiki/ISContextMenu

[silent zealot]

For me the font/outline/color is enough to tie things together.

[eternal tiger]

I try not to use free stuff. The icons I'm using for this mod I actually paid for and got royalties to use them.

I've had alot of friends run into issues using "free" stuff. So I just pay the artists lol.

[silent zealot]

And the same vignetting overlay, but at different levels based on the background.

[eternal tiger]

I don't know if I'll post more than just the one mod, but having a unique title would help distinguish them.

[vast pier]

I mean game-icons.net is Creative Commons license, and everything is made by them.
It's not "free" like google images, it's free like public domain stories

[eternal tiger]

Good to know. I'll have to give them a look.

[vast pier]

I always say this when it's brought up, but you will genuinely recognize a lot of their icons

[silent zealot]

Free like speech, not free like beer?

That's the common analogy I've seen for open source software.

[eternal tiger]

Wow actually I do recognize a lot of these.

The DND Program I use must use this as a library for icons.

[vast pier]

Here's the icon sheet, containing every single icon.
Despite how I never see anyone talk about it, this resource is used more frequently than people realize.

I try to show it off whenever possible cuz I think it's neat

[eternal tiger]

I just double checked. Dicecloud does for sure use these

good to know!

[vast pier]

Yeah it's a great resource!

[eternal tiger]

Wow I might need to use some of these for the Symbols.

[silent zealot]

It is!

[eternal tiger]

Just found these beauties'

Now to figure out how to setup an Options screen so you can enable and disable these because

there is alot

[vast pier]

found?

what're they from?

[plush wraith]

Turns out you can use player:getCurrentState() but it seems like only some of the states allow you to call getName() so you can just tostring it and match a pattern

[bronze yoke]

states are singletons, so you can compare them to the instance

[plush wraith]

Ya but only some of the states are exported it seems

[bronze yoke]

oh i see, some aren't exposed

that's a pain and likely unintentional

[plush wraith]

Go figure its one of the ones I needed 😂

But now you can run face first into a wall and drop your smoke

[eternal tiger]

I found a code that can help me write my code LOL

or rather a Script to help me write my code.

Adding numbers to all these would be horrific to do by hand. Especially since there is a lot more for every other category.

wait

WAIT i messed it up

Got it working

lol

[grizzled fulcrum]

what in the fuck are you doing

[vast pier]

Can't be produced by a recipe, but I have the recipe open and visible?

[grizzled fulcrum]

is that you writing them?

[grizzled fulcrum]

please just do

local instance = MapSymbolDefinitions.getInstance()
for i = 1, 41 do
    local name = "TF" .. i .. "-Vehicle"
    local path = "media/ui/Lootablemaps/Vehicles/Vehicles/" .. i .. "-Vehicle.png"
    instance:addTexture(name, path, name)
end

also you have 2 of the same Vehicles folder, why?

[vast pier]

changing the recipe module to base fixes this issue.
It also fixes an issue I hadn't brought up, which is for reverse engineering recipes

[eternal tiger]

Thats a thing you can do?!

Lets see how this works.

[eternal tiger]

I have a few subfolders. One is just Vehicles full of Cars, another is Vehicle Wrecks, and so on.

Actually now that I'm looking at this I feel like an idiot LOL

[grizzled fulcrum]

you should really learn basic lua, it will help

[eternal tiger]

Yeah that's what I'm working on. I know basic C++ and Java, but its been about 6 years since I've last modded. I should go take a refresher course.

Also that code won't work as is. The second instance of name in

instance:addTexture(name, path, name)

is referring to the Category name, which would just create 41 categories.

Thank you for jogging my memory. lol

[ancient grail]

i have a code for fetching the burnt/wreck versions of vanilla vehicles

not sure if you need it tho

[eternal tiger]

I'm just making Map Icons

[ancient grail]

ayt yeah do what aoqia mentioned and just run everything on a table

your 1k lines of code becomes 6

[grizzled fulcrum]

I tried to write it based on the code you showed before, so idk if thats actually accurate, but the concept applied is the same (using for loop)

[vague marsh]

learning programming fundamentals will help you a lot when transitioning to any language, and yea you should dip your toes again on coding 6 years is too long😆

[native swift]

does anyone know how the "chance" works in distribution Lua? for example in the Authenticz mod, The Clown says "chance=0.04". how does this translate to percentage? im having trouble understanding what the numbers translate to as far as rarity goes

[jaunty marten]

#mod_development message

[vague marsh]

i think the chance value is not a direct percentage, from what i understand it acts as weight compared to other entries on the dist list. not sure tho but thats what i see it

[native swift]

tht makes sense cuz the percentages are actually impossible. i saw a freddy and a jason next to eachother which would be 1 in 10 BILLION if it were direct percentages

[vague marsh]

for example you will add all the chance value then you will divide the item chance value by that total to get spawn %

spawnrate = (itemchance/total of all chance) * 100

this is how I see it, similar to some of the other programming projects I'm working on

don't take my word for it tho, im also not sure about pz

[small topaz]

I am modding some ui elements and the vanilla code contains several commands of the form
self:drawText(someText,...)
Is it possible to access the text after the text has be drawn? Maybe deleting it or changing its position? Btw, those commands are executed in the respective ui's render() function.

[umbral raptor]

Does anyone know where the vanilla .oncreate for recipes are in the LUA files?

[small topaz]

in lua/server/recipecode.lua

[umbral raptor]

need some help

in the wiki it says the item's ID should be
farming.Strewberrie

do I have to put it as so in recipes?

[bronze yoke]

no, there is no weighting at all

the chance of other items spawning doesn't affect another item's at all, except in the very rare case where so many items have already spawned that the container is full

[winter star]

howdy, im new to modding and decided to make a texture mod that that puts soyjak faces on zombies and players, as well as changing the overall "skin" tone to be white like how soyjak drawings typically are, because it's funny. so far i've made textures for the male player body, i made the base character texture grayscale and pasted the face i wanted over the texture, made sure the names of the images and folders were all correct like three times, but the texture still wont load. it just makes the player invisible. any insights as to why it won't work?

[bronze yoke]

the chances are technically percentages however there are so many modifiers applied, many of which are not predictable, that it isn't easy to determine the actual chance of something spawning

[blissful meteor]

Has anyone done any work relating to keys doors? I'm wanting to improve fort redstone next update to have some endgame content in the underground area.

I want to make keycards that will open doors in the underground area. If there is a mod that already does something similar could someone point me to it so I can look through the code

[true nova]

idk any mods that have done it but keys have ids and you can set the doors keyid and make a new key and set its id. I'm sure you can make a keycard item and make it be a key wth this id

key:setKeyId("any int you want to be id")```

[vague marsh]

good to know, thanks for the info!

[storm trench]

Does the game spawn anything in (not in containers) in LUA? And if so, where??? Thanks.

[true nova]

what are you trying to do? spawning items in the world can be done with IsoGridSquare:AddWorldInventoryItem(InventoryItem,0,0,0) the 0's being the coordinates of the item within the square

[eternal tiger]

Not sure what I did but now my game won't read ANY mod files pertaining to MapSymbolDefinitions. Time to verify game files. LOL

[blissful meteor]

Thanks, How do assign it to the door though, I want to make a a door like the one on the redstone bunker need a keycards, and can we make tiles unsledgeable in 42?

I'm hoping since we have the basement walls they have made it so some tiles can't be destroyed

[true nova]

IsoDoor:setKeyId("your key id") idk if keyids can be set in the tiles but if you get your door through the event loadgridsquare you can set it like that

and with removing sledge destroy option on things i dont see that as an option but the context option can be removed if it is opened on the doors

[sturdy salmon]

Hello, good afternoon. I was working on identifying the vehicles, since perhaps at some point, I have to track some of them. I saw that there is a database of them, and that it has an id. However, from lua, I try to access that value, and it seems to not always be the same. Am I making some mistake?

local vehicle = character:getVehicle() -- BaseVehicle
local vehicleGetID = vehicle:getSqlId()

From now on, any help is welcome. There is another method, but it didn't work for me either. I'm on build 41. Thanks.

• https://projectzomboid.com/modding/zombie/vehicles/BaseVehicle.html#sqlID
• https://projectzomboid.com/modding/zombie/vehicles/BaseVehicle.html#VehicleID
• https://projectzomboid.com/modding/zombie/vehicles/BaseVehicle.html#getId()

[storm trench]

I was intended more of a "by chance" and "by location" sort of deal. Not manually placing every spawn.

[storm trench]

And if it helps any, I intend to use a similar system to how generators are spawned in. So if, in the end, it does require manual coordinates then it is what it is.

[true nova]

so specifically with generators i think they have preplaced map objects that they just replace as they load

but how ive seen others spawn what they want is using loadgridsquare event checking for a buildingid so not to repeat spawns, and getting the roomname to see if you want to spawn there and then getting objects in the room to place on

[storm trench]

Quiteee... interesting... hmmm. Thank you so much! I have some ideas to try now. ;3

[lapis wigeon]

I'm trying to make a simple mod for myself that is just one crafting recipe. I can get the mod loaded in but the recipe doesn't show in the crafting menu. Is the wiki still correct for B42 or do I need something more than just configure a recipe.txt file?
https://pzwiki.net/wiki/Recipe_scripts

[bronze yoke]

no, this for b41, b42 has a completely new recipe system

there isn't really any documentation on it, look at the vanilla ones and other mods

[random finch]

(B41) So, I am working on a mod that handles InventoryPane. I thought items double-clicked within the players inventory transferred to a loot container or floor, but they only equip those items - Is that correct vanilla behavior? Seems to be, but I swear the items transferred on double-click.

[lapis wigeon]

Thanks, I think I what I need to do

[random finch]

Yes, I tested with no mods, and this is the behavior I get, but like I said, I swear the items transferred on double-click.

[blissful meteor]

Thanks, I'll save this for when I get to it

[storm trench]

Hate to be a bug again, but are the building names shown upon right-click in -debug mode applicable names for me to use in a function targeting specific buildings?

I tried the PZ wiki for POI names but... yeah not there lolll.

[brave bone]

can someone help me understand to turn this image into that, im sooo confuse what is happening on the left image

[bright fog]

Left image is a texture and the UV map of the 3D object puts its vertex etc on this texture to show on the various faces of the object

[bright fog]

You mean like unique names of the buildings ? I don't think that's stored in any way in the game

[brave bone]

oooooh... Thank you 😄

[storm trench]

No, like... "storageunit" or "burgerkitchen" or "elementaryschool" / "elementaryclassroom". They have specific names if you right click on the ground in -debug mode and you get something like this:

[bronze yoke]

those are the room names, yeah you can use them in mods

[bright fog]

Anything you see in the UI is in the Lua

So you can easily find how the game accesses these by checking the code which makes this context menu option

[bronze yoke]

not all ui is lua but most

[bright fog]

Yea you're right

[storm trench]

Yea, so I was hoping there was a list somewhere of these and I don't have to check each place I want physically in game.

[bright fog]

Context menu options are Lua at least

[bright fog]

I don't think so but that might be interesting to have such a list

[bronze yoke]

there will probably be an entry for every room in the distributions

an actual comprehensive list is kind of pointless since the mapper can put literally anything in there

[storm trench]

Only 25,000+ line to peruse hahaa.

[bright fog]

fetch.clickedSquare:getRoom():getRoomDef():getName()

That's how the game gets the room name

[bronze yoke]

not sure if the b42 map has it but the b41 map site had a room names overlay which may be faster than in-game

[bright fog]

Not much in the java at least

public boolean isShop() {
      String var1 = this.getName();
      if (var1 == null) {
         return false;
      } else {
         if (ItemPickerJava.rooms.containsKey(var1)) {
            ItemPickerJava.ItemPickerRoom var2 = ItemPickerJava.rooms.get(var1);
            if (var2 != null && var2.isShop) {
               return true;
            }
         }

         return false;
      }
   }

ItemPickerJava.rooms

Perhaps

[bronze yoke]

there isn't a fixed list of rooms

the mapper can put whatever string they want in there

ItemPickerJava.rooms is just how the game stores the distribution tables

[bright fog]

Tbf you could easily make a code which picks up every loaded room and get their name, and add them in a key table

And just TP around the map

Mapping every possible rooms

[bronze yoke]

you'd have to load every single square on the map though

[bright fog]

No

I mean

No definitely not

You can just go around every cities

I don't think there's that many room options, most are shared anyway ?

[bronze yoke]

yeah

seems really high effort for something you can just look on the map site for

[bright fog]

Yeah but the map you need to take note of every unique rooms ...

While this list, we could actually write down somewhere in the wiki

[bronze yoke]

if you want to update it every map update 🤷‍♀️

it sounded like they were trying to target specific rooms so just checking those out on the map would be way faster

[bright fog]

I mean that's a problem sure

But if the majority of the rooms are listed, and proper version is noted for the list

[bright fog]

No idea what they planed on doing but my guess was getting a general view of what's available ?

Actually how about asking the mapping Discord

[storm trench]

Which map site are you speaking of?

[bronze yoke]

https://b42map.com/

[bright fog]

Needs to be the B41 one no ? You said it's only in the B41 version the room names ?

[bronze yoke]

i said i wasn't sure, i checked now

[bright fog]

ah nvm

Seems to be in the B41 version tho, at least it's not in the B42 version ?

[storm trench]

Thought so. Something about this doesn't seem exact tho.

[bright fog]

You need a persistent identifier ?

[storm trench]

Actually nevermind, it appears correct. Thanks all!

[sturdy salmon]

Yeah. I need to identify the vehicle, in case someone takes it, to have a record and be able to search for it on the map. I would need the ID to be unique, however, I get different results within the same game.

I'm making a log, to know, if someone takes a car, to keep a record, and to be able to know where they leave it.

[bronze yoke]

the sqlid is the one i would expected to be persistent

that's its id in the vehicle database so it'd be strange if it changed

if it really isn't for some reason you can just attach a randomly generated id to the vehicle's mod data

[sturdy salmon]

I'm using it and it returns different results. It's strange. I assumed the same. That it would take the ID of the table, and that it would not change.

I need unique information that identifies the vehicle. I have already identified the player. Then, I would need to see where the tow cars action is called, so I can maybe add a triggerEvent or something custom.

Although I don't know if triggerEvent can be created or just invoked.

[bronze yoke]

you can register events with LuaEventManager.AddEvent("myEventName")

[sturdy salmon]

Thanks.

Does the method executeQuery of the GlobalObject, does it work in build 41? https://projectzomboid.com/modding/zombie/Lua/LuaManager.GlobalObject.html#executeQuery(java.lang.String,se.krka.kahlua.vm.KahluaTable)

[silent zealot]

try getId() instead of getSqlId() - I'm not certain that is persistent between restarts but it's worth checking. Same for keyID()

[sturdy salmon]

Thanks. I'll try it.

[silent zealot]

I wonder if SqlId is like the place I worked at where they insisted there was no need for an ID field on the excel sheet of tasks because they could just reference the row number and then got really confused when references to "item 67" stopped making sense because rows had been added/removed.

[sturdy salmon]

I'm looking at the possibility of adding some extra fields, because for example, I don't have information about the car model. Just the ID, and the position.

[silent zealot]

Log towing info too or people will steal cars via towing,

[jaunty marten]

yea, sqlid is a perfect name btw xD

int allocateID() {
    synchronized(this.m_usedIDs) {
    for(int var2 = 1; var2 < Integer.MAX_VALUE; ++var2) {
        if (!this.m_usedIDs.contains(var2)) {
            this.m_usedIDs.add(var2);
            return var2;
        }
    }

    throw new RuntimeException("ran out of unused vehicle ids");
    }
}

void setVehicleLoaded(BaseVehicle var1) {
    if (var1.sqlID == -1) {
    var1.sqlID = this.allocateID();
    }

    assert !this.m_loadedIDs.contains(var1.sqlID);

    this.m_loadedIDs.add(var1.sqlID);
}

No wonder things broke when I spawned the 2147483648th car

Asked in the mapping Discord

[storm trench]

I appreciate it so much. Thanksss.

[eternal tiger]

I have 0 clue why, but my Lua file just stopped being detected by the game. I had to delete the entire file and copy and paste the contents back into the mod files to get the mod working again. I've changed nothing LOL

Also does anyone know if the MapSymbolDefinitions file can actually be used apart from the standard array? I keep trying to put my own code in to condense this massive file down, but the game refuses to read it properly and I can't figure out if its because of my inexperience with Lua or if I have the files in the wrong location cause I'm new to modding Project Zomboid or if its another thing entirely.

is this not Zombie Scan Budget?

🤨

[silent zealot]

No, It's ZombiesCanBudget.

[vast pier]

why tho 😭

In other news, I think my munitions mod is just about ready to release

Fun fact, molotovs, and fire crackers are the only bombs that need a lighter in your off hand. Not just any sort of firestarter, only items with the "Lighter" tag

One of the things I'm changing ofc. Cuz why couldn't you use a match in this situation?

or a lit candle?

I'm also making it so the normal pipe bomb requires something to light it, and adding in a separate version that has an electric igniter.
The electric version is required for crafting the timer/remote versions.
There's a recipe to craft the electric version directly, and one to just add an electric igniter onto an existing pipe bomb

Aerosol bomb is gonna basically be a weaker pipe bomb that causes small fires.
Not really sure what if anything should be changed about the firebomb/molotov/smokebomb so they're relatively unchanged

Main difference is they are actually in loot tables now

[silent zealot]

Are the recipes to make them more available? I think right now one of those is strictly behind a profession choice

[silent zealot]

Add The Anarchists Cookbook to loot tables with all the explosive recipes

[vast pier]

They spawn as loot, and I added the ability to reverse engineer them :)

There's also a military improvised munitions handbook which includes recipes for all of them 👍

[vast pier]

The anarchist's cookbook is a joke, most of the "recipes" are incomplete and don't use actual measurements

It's more of an edgy book than anything

the handbook I've been researching has proper recipes, measurements, and procedures for making propellents and primers

[vast pier]

Also adding in a can bomb, which you can craft from tin cans/water ration cans, propellent, and scrap/nails

    craftRecipe MakeCanBombNails
    {
        timedAction = MakingElectrical,
        Time = 100,
        NeedToBeLearn = True,
        Tags = AnySurfaceCraft,
        category = Electrical,
        inputs
        {
            item 1 tags[Primer],
            item 1 [Base.TinCanEmpty;Base.WaterRationCanEmpty],
            item 3 [Base.Nails],
            item 10 tags[Propellent],
            item 1 tags[Binding],
        }
        outputs
        {
            item 1 MunitionMag.Canade,
        }
    }

    craftRecipe MakeCanBombScrap
    {
        timedAction = MakingElectrical,
        Time = 100,
        NeedToBeLearn = True,
        Tags = AnySurfaceCraft,
        category = Electrical,
        inputs
        {
            item 1 tags[Primer],
            item 1 [Base.TinCanEmpty;Base.WaterRationCanEmpty],
            item 1 [Base.IronScrap;Base.BrassScrap;Base.AluminumFragments;Base.GoldScrap;Base.SilverScrap;Base.SteelFragments;Base.Aluminum],
            item 10 tags[Propellent],
            item 1 tags[Binding],
        }
        outputs
        {
            item 1 MunitionMag.Canade,
        }
    }```

It's basically the same as an aerosol bomb, but requires something to ignite it and has a smaller explosion radius

recipe will probably change a little bit before I release it

[vast pier]

The only bomb in vanilla that isn't profession locked is the molotov.
Though in vanilla you can actually find randomized schematics to unlock the rest of the bombs. (I think this is exclusive to B42)

[vast pier]

I decided it's not actually gonna include the
Aerosol Bomb
Fire Bomb
Smoke Bomb
This is because I'm basing it off of a real life book.
I'm also making it so the veteran profession knows how to make normal pipe bombs, and can bombs

Electrician will inherently know how to add an electric igniter to a pipe bomb, and will also be unlocked automatically by electric level.
Engineer will know all of them inherently

All of this together means you could start as any profession, find a pipe bomb in the world, reverse engineer it, hit level 4 electric, turn a pipe bomb into an electrically ignited one, and then reverse engineer that to unlock the recipe to directly craft them instead of just adding it on afterward

Or start as a veteran and get level 4 electric, craft a pipe bomb, add an electric igniter, and then reverse engineer it

Oh yeah I also made it so bombs can be put on your belt, and added in "triggerExplosionTimer" to pipe bombs to make them explode faster.
I found it very awkward to throw a pipe bomb and have it sit in the air for a long period of time, so I took "triggerExplosionTimer" from the aerosol bomb and added it to the pipe bomb and can bomb

Oh and uh, noise makers are buffed too. forgot to mention those

[silent zealot]

Oh yeah I also made it so bombs can be put on your belt,

Please tell me nothing stops you from putting them back on your belt after starting the timer...

[vast pier]

default duration is half an hour in game, increased to an hour and a half
default range is 17 tiles (an alarm clock is 15), increased to 120 tiles

[vast pier]

Not sure what you mean by starting a timer?

[silent zealot]

Noisemakers defiitely needed a buff, in vanilla thy were terrible.

[vast pier]

Yeah 120 tiles seems dramatic, but why would you use the resources to make a noise generator when you could fire a single pistol bullet and have a much further draw radius

[silent zealot]

1. remove pipebomb from belt
2. activayte pipebomb
3. change mind. draw another weapon, replacing pipebomb.
   4)...
4. BOOM

[vast pier]

I don't think you can activate the bombs without placing down or throwing them

[silent zealot]

120 tiles is ~1/3rd the area of a shotgun. Seems fine.

And rewards people for preparing & using tactics.

[vast pier]

draws attention for an hour and a half before needing to be picked up and reset

I think they're infinitely reusable, don't know if I can change that in some way

I think it's fine given the commitment required to get to that point in the first place

Hey now that I'm thinking about it

[silent zealot]

CanBeReused = TRUE,

change that to FALSE and it should be single use.

[vast pier]

why can the fire bomb be used without without something to ignite it? while the molotov needs something to ignite it?

isn't it just alcohol vs gasoline? I don't think gas explodes on impact in a plastic bottle?

also I hate that the flame bomb is in a plastic bottle... gasoline melts most plastics

It's not safe to put gasoline in a water bottle

[silent zealot]

If you're really keen you can make a device you throw, and on impact a glass bit breaks a and a chemical reaction ignites it.

[vast pier]

Would it still be active for an hour and a half tho is the problem

[silent zealot]

This woudl be suicidal the way we run/climb/fall/bet in melee in zomboid.

But you coudl do it.

[vast pier]

I mean the aerosol bomb recipe kinda implies we already do that

[silent zealot]

honestly, no idea... on a quick look I'm not seeing how the noisemaker works, unless the sound is defined to last for 30 minutes

[vast pier]

I'm just gonna make the normal version require an igniter

I think it would still work, cuz the smoke bomb makes 10 in game minutes of noise while not being reusable

[silent zealot]

Maybe firebomb is meant to be a fuel-air explosive?

[vast pier]

the recipe is a bottle, a rag, and gasoline

It just magically ignites itself

[bronze yoke]

i wouldn't take the recipe too literally, that recipe hasn't been changed since the game had about 5 items in it

[silent zealot]

so it has a small amount of explosives and an electical trigger to spread the fuel and then create a big airburst with resulting pressure-wave

[silent zealot]

that is also a very good point!

hahah

[vast pier]

I will take every recipe literally and you can't stop me

[silent zealot]

So they wrote the recipe 20 years ago and never looked at it agian because explosives are horrible and no-one uses them. That seems likely.

[vast pier]

I'll just do what I did to the pipe bomb, vanilla version needs igniter, and then a new version that doesn't need one cuz electric ignition

Also how does the smoke bomb work? does it burn the rag, and react to the cold pack to create smoke?

is it technically steam?

[bronze yoke]

steam from the steamed clams we're having

[vast pier]

Ah no I think it actually reacts to the paper burning?

[silent zealot]

Possibly not, looking at the java if it's not reusable it is removed after it explodes which deletes the isoobject so that may also kill the sound being updated.. you'd have to test to make sure.

[vast pier]

idk either way, needs an igniter, vanilla doesn't have one

[tacit pebble]

I'm also curious so I asked to GPT and

If the game assumes that the cold pack contains ammonium nitrate, and you combine it with rags/newspapers, the idea might be that the pack is broken open and the reaction starts to heat up the rags, causing them to smolder and produce smoke.

idk anything about chemistry so idk

[vast pier]

Maybe I could just increase the explosion duration time then

As the smoke bomb has an explosion duration of 10, which is how long the sound lasts

[vast pier]

https://www.youtube.com/watch?v=koHoi9CcUPA

It's not as strong as what we see in game obviously, but it's functional in the same way

[tacit pebble]

oh interesting vid

[vast pier]

Still, would need an igniter, which in vanilla it does not use one

It's weird how molotovs are the only bombs that seem to have gotten any attention, probably since they aren't profession locked

"oh nobody uses the other ones, let's just work on the one people use"
Nobody uses them because they don't get worked on

[tacit pebble]

true

it's funny that we need at least 5 pipe bombs to kill a single zombie

[bronze yoke]

i think they know there's nothing short of a complete overhaul that would get people to use them

[tacit pebble]

that should be true too. it's just not started yet like vehicles i guess.

[vast pier]

I feel that's not entirely true, they could easily increase the damage of the aerosol/pipe bombs and they would immediately become more viable

Would give an alternative to horde clearing that doesn't involve a campfire

It is nice though that they are no longer profession locked in B42

but relying solely on some random schematic RNG doesn't sound great

[bronze yoke]

did they change the skill requirements at all

it's one hell of a combo of profession lock + needing high levels in a useless skill + they feel terrible to use + they're shit

[vast pier]

for what?

[bronze yoke]

any of the engineer bombs

[vast pier]

The recipes don't have level requirements, at least not the basic ones

noise maker requires level 3 electrician, and auto learns at level 7

[bronze yoke]

did they have skill requirements in b41 or did i misremember that?

[vast pier]

If you mean the ability to add the triggers n' stuff, yeah those are still pretty high

Adding a tier 3 sensor to a bomb requires....

electrical 6

same with a tier 3 remote controller

The bombs themselves just need the recipe tho

Not really sure why putting the sensor/remote trigger on the bombs requires the same electrical knowledge needed to actually craft them though

you'd think it would be a lot easier to know how to attach it rather than how to create it

[thin walrus]

Hello everyone! I have a question: I know how to translate one mod, but how do I create a collection of translations in one of my mods for several different other people's mods?

[silent zealot]

You should be able to combine multiple translations files together.

For example if mod1 has ItemName_XX

    ItemName_Base.Foo = "Fooin",
    ItemName_Base.Bar = "Barin",
}```

and mod 2 has ItemName_XX
```ItemName_XX = {
    ItemName_Base.Wiz = "Wizin",
    ItemName_Base.Zoom = "Zoomin",
}```

you can combine those to one file, 

```ItemName_XX = {
    ItemName_Base.Foo = "Fooin",
    ItemName_Base.Bar = "Barin",
    ItemName_Base.Wiz = "Wizin",
    ItemName_Base.Zoom = "Zoomin",
}```

[slim swan]

Is there an event that can be triggered before the game saves or closes?

[fallen merlin]

Helloo, I am new to modding the game and need some help with it. I have created a mod with the right structure, as following:

MyMod/
│── media/
│   ├── lua/
│   │   ├── client/
│   │   │   ├── MyModFile.lua   
│── mod.info
│── poster.png```

My mod info File looks like this:

name=My Mod
id=MyMod
poster=poster.png
description=XXX
version=1.0```

And the folder for the mod is located under users/myUser/Zomboid/mods/

Unfortunately the mod doesnt show up in the game. I am using the latest unstable build. Does anyone know what exactly I am missing out? Thank you for your help in advance

[bright fog]

OnSave I believe

[bright fog]

B42 ?

[fallen merlin]

Yes

[bright fog]

Then that's wrong

https://pzwiki.net/wiki/File_structure#Mod_folder

[fallen merlin]

Thank you so much, this seems to be the issue. I will try it out 🙂

[fallen merlin]

Worked, I can see my mod now in the game. Thanks again for the quick help 🙂

[thin walrus]

thanks for your help, you are my hero!

[silent zealot]

😊

[fallen merlin]

I have another question. So my mod is almost done, it's about healing zombification and wounds. It seems to work almost completly, it just can't heal lacerations and I don't know exactly where to find the method to remove it. This is what I have:

        -- Heals all wounds
        for i=0, BodyPartType.ToIndex(BodyPartType.MAX) - 1 do
            local bodyPart = bodyDamage:getBodyPart(BodyPartType.FromIndex(i))
            bodyPart:SetBleeding(false)
            bodyPart:SetDeepWounded(false)
            bodyPart:SetBurnTime(0)
            bodyPart:SetScratched(false, false)
            bodyPart:SetBitten(false)
            bodyPart:SetFractureTime(0)
            bodyPart:SetCut(false, false)
        end```
I thought "deep wounds" would be lacerations, but unfortunately it's not. Does anyone know how to set lacerations to false?

[fleet bridge]

its setCut. only SetBitten has a capitalized S. check the cheat panel lua code

[fallen merlin]

Thank you for that as well, I looked now in the docs and yeah Idk I just thought they are all written capitalized

The last issue seems to be this:

        local bodyDamage = player:getBodyDamage()
        bodyDamage:setMoodleLevel(MoodleType.Queasy, 0)

I am confused with that tbh. The method setMoodleLevel doesnt exist in BodyDamage according to the docs. But somehow, it works and throws an error that tells me following:

function: CurePlayer -- file: CureZombification.lua line # 12 | MOD: Cure Zombification
function: onMouseUp -- file: ISButton.lua line # 56 | Vanilla

ERROR: General      f:116, t:1740490781807> ExceptionLogger.logException> Exception thrown
    java.lang.RuntimeException: Object tried to call nil in CurePlayer at KahluaUtil.fail(KahluaUtil.java:82).
    Stack trace:

Sorry for all the questions, it's my first time modding a game

[vast pier]

Do not worry about asking questions, it's the only way to learn

[fleet bridge]

i've never seen MoodleType being used before. are you sure that's a thing and not something that was imagined by Copilot or something?

[vast pier]

Porting a mod from B41 to B42 and it seems the guns are flipped? Any idea why?

[fallen merlin]

It really works, I have a save where I am Queasy due to zombification and when I press the "Heal" button, it removes the Queasy moodle and throws an error at that line. I guess that error is preventing the Laceration to be healed (I corrected the setCut() method already)

How would you remove a Moodle from a player object then?

[frank tide]

Somebody please make a tile pack /mod to add more garage items to the game for b42 engine stands/displays,tire balancers ect.

[small topaz]

Hello everyone! Is it possible to change a specific parameter of a specific clothing item's xml file while the game is running via lua coding? Specifically, I want to temporarily delete the xml paramter
<m_UnderlayMasksFolder>media/textures/Clothes/BulletVest/Masks_BulletVest</m_UnderlayMasksFolder>
which can be found for several vanilla clothing items (in my case, it is mainly relevant for bullet proof vests). Thanks for any ideas!

[knotty stone]

I will leave this here if anyone wants to finish this, i give up with my limited lua and api knowledge at this point. I disabled that crops are killed when you drive over them. The last thing to finish this is in AgroMain.lua line 176 filling the "seeItems" variable, there is something wrong there and AgroUtils.removeContainerItems(seedItems) fails to read it. Good luck

[fleet bridge]

it works because you're healing the wound, it throws an error on the queasy moodle because its not a real thing

[ember leaf]

Hey folks is it possible to add a sickness modifier to a tablet/pill? I.E you take Painkillers but overuse causes sickness?

[vague marsh]

https://tenor.com/view/it's-possible-it's-very-possible-perhaps-googas-gif-12644615660336645261

[ember leaf]

First time trying to mod Zomboid (or anything haha), figured I would work on the medical system as I work in the sector, but been trying to figure out how to add sickness and modify the base player stats

Think I have a hang of the creation of new items using text, it's just causing increases in sickness/fatigue while still keeping it as a drainable item, just I notice when I fatigue is added to painkillers for example and it's drainable it doesn't apply, but if I apply it to antibiotics which has the food class it works

Don't know if its dependent on that?

[vast pier]

Don't know what bip is used for attachments tho, I already tried seeing if it was effected by bip01_prop1

[vague marsh]

you can use setFoodSicknessLevel() in a script to add sickness when taking pills

[vague marsh]

its bip01 yea

[ember leaf]

Ah, haven't experimented with the scripting side yet, doing the project to to teach myself LUA and see if I can come up with something folks can have fun with

Thanks 🙂

[vast pier]

back attachment tho>

?

[vague marsh]

bruh its gone

[vague marsh]

yes its bip01, thats what i use on the attachment

[vague marsh]

you can join the modding server for resources, i cant send the link it got blocked.

[ember leaf]

Where can I find the link?

[lapis wigeon]

What the fastest way to load your mod changes in debug mode?

[storm trench]

Is there something different with the way semicolons work in B42 lua's?

[bronze yoke]

probably not

[bright fog]

There's no use to semicolons anyway

Remove them

[grand cloak]

do you guys know what this means

[bright fog]

uh

[storm trench]

I figured as much, but in one instance using one seems to be fixing a bug. No idea why yet.

[bronze yoke]

it shouldn't be

in lua semicolons are just treated as whitespace

the only exception is they can take the place of commas in table initialisers

neither of these uses are common or recommended though

[storm trench]

Yeah, it's really weird. Errors galore without, none with. I am half tempted to go back to Build 41 and see if the code works fine in 41.

[trim quartz]

Hey all, how do I find the correct X and Y to open a window center screen please?

[queen oasis]

something along the lines of

x = (getCore():getScreenWidth() / 2) - (your_UI_width / 2)
y = getCore():getScreenHeight() / 2) - (your_UI_height / 2)

[trim quartz]

fantastic, appreciate it

[silent zealot]

Assuming B42: What folder names are in use, (e.g: 42,42.0, etc) and what is in the mod.info?

I'm guessing something in mod.info is specifying what version of the game the mod is for.

[storm trench]

Do you happen to know any off the top of your head that use this? Build doesn't matter, I just want to take a little look under the hood. My script is running fine but the items refuse to spawn and I'm not sure why.

[silent zealot]

Different process, but Excalibar adds a number of fixed spawn via lua.

It does some stuff to build a table of things to add, then calls this via EventsEveryTenMinutes:

P4Excalibar.CheckSpawn = function()
    local spawnReserves = P4Excalibar.getSpawnReserves()
    for k,v in pairs(spawnReserves) do
        local square = getSquare(v.locx, v.locy, v.locz)
        if square then
            if v.item == "Zombie" then
                local crawler = true
                local isFallOnFront = (ZombRand(2) == 0)
                local isFakeDead = (ZombRand(2) == 0)
                local knockedDown = true
                spawnZombie = addZombiesInOutfit(v.locx, v.locy, v.locz, 1, v.outfit, v.femaleChance, crawler, isFallOnFront, isFakeDead, knockedDown, false, false, 2):get(0)
                if not isFakeDead then
                    spawnZombie:setHealth(0)
                    spawnZombie:DoZombieStats()
                end
            else
                local spawnItem = square:AddWorldInventoryItem(v.item, v.x, v.y, v.z)
                spawnItem:setWorldZRotation(v.r)
                spawnItem:getWorldItem():setIgnoreRemoveSandbox(true)
                spawnItem:getWorldItem():transmitCompleteItemToServer()
            end
            spawnReserves[k] = nil
        end
    end
end

So it's just checking if each square is valid (presumably they will only be valid if close enough to be loaded) and if so, spawn something (item or zombie) and remove the entry from the list of things to spawn.

[storm trench]

That is beautiful. Hmmm. I will absolutely be taking this into consideration. THANK YOU! 💚

[silent zealot]

It's a great mod too, if you want a bit of fantasy "assemble the artifact from multiple pieces" questing.

If a vanilla file declares a local variable like this, is there any elegant way to change it? Or do I have to patch every function that uses it?

[bronze yoke]

there is no way to change it

[silent zealot]

Oh well. Patching functions it is.

...or I just edit my local copy of the file and don't make it a proper mod.

[bright fog]

Current WIP of craftRecipe
https://pzwiki.net/wiki/CraftRecipe_(scripts)

This should help people who requested a proper guide on craft recipes

I'll try to finish it tomorrow :)

[faint ingot]

We (I) need a tiny mod that locks the inventory windows in place. But I lack the skills required to make it.

[bright fog]

Wdym ?

[faint ingot]

The inventory windows. I keep dragging them by accident while dragging items around quickly.

[bright fog]

I'm gonna be honest, no one will make your idea unless you do it yourself

Most mod ideas get lost

[faint ingot]

The miniature health bars mod has a locking button so you can't do that. It would be super nice if it was there for inventory windows

[bright fog]

That are thrown here at least

[faint ingot]

I'm just throwing it out there.
I lack time to learn. Hopefully someone sees it and agrees.

[silent zealot]

Every modder has a huge pile of high-level ideas, then gets distracted and does something else instead.

[storm trench]

I used this inspiration to use spawnReserves and it's working flawlessly. Not even a hitch in lag; billions of times better than loadGridsquare... now if only it would actually spawn my object. That's what has been fighting me the most today.

[silent zealot]

I guess there might be an issue if EveryTenMinutes isn't often enough and the player can load the area and reach it before items spawn, but for Excalibar that's plenty of time... the spawn locations are things like "inside Rosewood prison" or "lowest level of the secret military base" and you're not getting to those places quickly.

[bronze yoke]

in build 42 you can check to spawn things during loadchunk

if done properly it's exactly as effective as loadgridsquare but literally hundreds of times more efficient

[simple helm]

anyone kknow where I can learn how to add new base models from CGtrader

[silent zealot]

Do you mean spawn a vehicle, or add a new type of vehicle to the game?

[simple helm]

I messed up i edited the message sorry

[silent zealot]

no probs, I do that constantly.

[simple helm]

is it hard to do ? can i just get a model from cgtrader and script it in game or do i need to poly crunch

[silent zealot]

What is the model for? item, clothing, vehicle, other?

[storm trench]

Yeahhh, it's probably going to have to be faster for me. Especially concerning how many places it will involve.

But I am thinking a 60+ tick interval (minimum, probably more).

[simple helm]

car carrier

[silent zealot]

You'll need to make a new vehicle, not just load in the model

and if you want to actually put cars on it... good luck.

[simple helm]

i mean there already a mod to put a car on a trailer, cant you piggy back off of that mod.

also why make a new vehicle from scratch if you can buy the base model work off of that

[silent zealot]

A vehicle is more than a model

it's a bunch of data on parts, mechanics interface, stats etc.

Not hard to do, at least if you can use an existing mechanic template instead of building a custom one because that looks super fiddly.

[simple helm]

yea similar to gtav adding modded vehicles

[silent zealot]

I suggest getting the model (or a free placeholder) and giving it a go.

[simple helm]

ik this dev he a really good dev everything is broken down etc

[tacit pebble]

btw idea is actually nice. I like that

[silent zealot]

got a link to that mod? I'm curious how they do it.

I wonder if they just put the car on top of the trailer and hope it stays there 🤔

[simple helm]

yea

it goes on the trailer and gets covered

wait wrong one sorry

https://steamcommunity.com/sharedfiles/filedetails/?id=2992677535

[silent zealot]

Ah, that makes sense - sounds similar to animal trailers, the vehicle is no longer a physical object in the world but can be respawned near the trailer.

[simple helm]

there a vid of him doing it also

[tacit pebble]

I think its not something easily possible but Since we have similar thing,the Animal trailer, it can be implemented if we give up the 3d models

yeah

[simple helm]

everything doesnt have to be like u lower the rams and drive it on just a hauler to haul more cars

[silent zealot]

then change the trailer model to add the cover, add weight, done.

You could almost certainly scale that up to a bigger trailer with multiple vehicles.

[simple helm]

i dont care about adding the cover just want someone to mod the car carrier in game

[silent zealot]

Alternative approach: https://www.youtube.com/watch?v=gM7jCBlxhzg&t=5s

[simple helm]

i thought it not hard to add ?

[storm trench]

And that mod also has issues where the cars despawn. Just a heads up. It's a tall task to do a mod like that, let alone a full carrier.

[simple helm]

end of the day its worth

[silent zealot]

Think about it this way: you're not just adding a new vehicle, you're adding new features/capabilities that are not in Vanilla Zomboid.

[storm trench]

I've been forking a B41 mod for the last 2 days and it's been hell. All I'm doing is expanding upon existing framework, too. So it's gonna be a lot of days to end before it's worth it lolll.

[silent zealot]

Honestly, it's a good idea but don't start with a focus on the model - just use a minimal model and build a proof-of-concept mod

[simple helm]

okay but forget about adding a new script rn just want to get the trailer in game first, if there are 18 wheelers with living quarters i think this is not far off

[silent zealot]

Even if that means a big flat rectangle that gets other rentangles added on top as cars are added.

That much will work easily - you can look at the existing big trailers.

AFAIK any living quarters type stuff is from RV Interiors, which is B41 only... I don't think anyone has been crazy enough to reproduce that when they could just make use of RV Interiors for more vehicles.

Hi all! How's going on?
I've a question regarding pz modding. I'm trying to achieve server-side mods. Is is currently possible in the dedicated server to specify server-only mods in any way? I didn't find anything tbh.
I was thinking in patching the NetChecksum class to skip files in media/lua/server, so I can ship the mod without the server files, but dunno if the game needs the server files for anything at all.

Thanks!

[silent zealot]

What do you mean by "server side mods"?

Mods that are on the server but NOT installed by the client?

[whole parcel]

Yeah

[simple helm]

well first thing first. I just want to get the hauler scripted in game who can do it. and what needs to be done ? if i need that base model first
done 1st step complete. ik there alot of steps but baby steps first

[silent zealot]

who can do it
You can!

[simple helm]

i dont know how to mod pz

let alone add modded vehicles dont i need to poly crunch it and add the paint etc

[silent zealot]

You don't know how to mod pz yet

the modelling/texture side I can't help with, but if you look at existing vehicle mods you'll see it's justa bunch of text files to define things.

[simple helm]

https://theindiestone.com/forums/index.php?/topic/28633-complete-vehicle-modding-tutorial/

this doesnt help me much

[silent zealot]

Where are you getting stuck?

[simple helm]

it not getting stuck i just need the PZ basics for adding NEW modded vehicles, do they have to be broken down in categories. what the poly count they need to be etc that i have not done in a minute bc pz is a bit different then gtav

[small topaz]

When modding in lua, it is necessary server and clients have the mod enabled. But you can still manipulate things on server-side only

[silent zealot]

Have a look at existing models, use whatever they do as guildelines.

[whole parcel]

I'm trying to find a way to not share some server files

[simple helm]

will that trailer work from cgtrader or no im sure that how others got there vehicles

i can use cgtraders tho correct ?

[bronze yoke]

for most mods that would actually work server-side you don't need to do anything complicated like that

you can just have a lua mod that pulls and loads lua files from the sandbox folder

[silent zealot]

If you can load it into blender and export as a .fbx you can use it, but that doesn't means it's a good starting point - if that image you posted is of the model it's massively more detailed than what you want for zomboid.

[bronze yoke]

there's already a couple executions of this concept floating around

[whole parcel]

Oh, so is it possible to require() outside the mod folder? Interesting

[bronze yoke]

i'm not really sure what they're called though

[bronze yoke]

no, but you can read the files as strings and load them

[whole parcel]

That's a great hacky workaround

[simple helm]

yea ik that bc the poly is at 38k bc his models are hq ik it wont look like that, but i can find one lower quality or polycrunch it i just need to know what the poly crunch limit for vehilces and ther no vehicles to download to look at

[small topaz]

this is not possible with mods which are officially supported by the game. though not sure about java mods or what happens when you directly manipulate the pz lua files in pz's installation folder (the latter is pbbly not a good idea).

[silent zealot]

Through java modding anything is possible... at least in theory. A lot of stuff is impractical.

[whole parcel]

Yeah, I was thinking on patch the NetChecksum class to skip server files tho

[silent zealot]

What do you mean there are no vehicles to look at? there are lots of modded vehicles.

[simple helm]

okay can i message you on the side or someone else that knows about importing a new vehicle like this ? trust i want to learn but i rather not asking alot if im not talking to the right person ?

[silent zealot]

Check the #modeling channel, or ask again here in a while and see if other people are around who do vehicle modding.

[bronze yoke]

otherwise, java mods can run serverside regardless because there is no java checksum, and pretty much anything else wouldn't work without a client mod anyway

[simple helm]

alright btw i did manage to find a download for a vehicle looking at the script now doesnt look like alot of lines just want to do it right. thank you tho

also asked in tsar discord and k15 hopefully i can get one of them

[silent zealot]

FYI: you can see the code for any mod, get the mod id from steam workshop:

downloaded content is under your steam installation, game id 108600

[small topaz]

oh, maybe a misunderstanding? I thought I just replied to this question: "I'm trying to find a way to not share some server files". Not related to vehicles

[silent zealot]

Sorry, my fault - I got the conversations crossed

[sinful ether]

Hey people, i just made a Lifestyle addon of 20 tracks for the Keytar. Anyone interested, i can stream some of the tracks before you try too.

[lucid oyster]

i asking a little technical question for anyone out there, is actually any way to give the player more hp? (not imortality just more health, so can bleed or get hurt more before death) i was triying to make gunfights a common thing but its hard to enjoy them cus how easily it is to die of a shot (i know its unrealistic) im just asking if is there a way trough lua scripts to do such a thing, so that players may survive and heal back up after a fight

i looked up mods and conversations on this chanel and i didt find anything

[copper abyss]

literally what I am doing right now and I hate it so much

[formal sky]

Hello, I've been looking to commission a mod on reddit. I've been contacted by a guy that was very enthusiastic, but the more we talk themore he sounds like a LLM, so before the discussion blows and they start harassing me for money, I thought I'd ask here:

I want a mod that records the amount of zombies in a chunk when the player enters it (or spawns when the game starts), and when he leaves that chunk, the mod compares the stored amount to the current count to see how many the player has killed, and deduces a small (custom) proportion of the killed amount from the chunk's maximum population (and records the amount of the newly entered chunk to do the same there). Is that possible at all?

Alternatively, when the player kills a zombie, that zombie's starting chunk has a small chance to get its max population lowered by 1. Same result, different way to do it. No clue of the inner workings of the game so I can't judge on the relative difficulty of either implementations.

before the discussion blows and they start harassing me for money

[umbral raptor]

i wish the console would tell u everything wrong with the code at once instead of giving it to u piece by piece as u crack down errors

[drifting ore]

Wtf is that

Is someone holding you at gunpoint

[tacit pebble]

im at my work 🤣 they want to check IE compatibility

[silent zealot]

monkey's paw curls you now get full java logs, so every error is 2000 lines of recursive stack traces.

Probably works a job where they still have apps that only work with IE6.

[bronze yoke]

it's not really possible for it to give accurate errors for future code, since everything's already messed up from the first error

[silent zealot]

can lua do try/catch blocks?

[bronze yoke]

they have pcall to call functions in protected mode but it doesn't really work

in zomboid anyway

[silent zealot]

googles "For many applications, you do not need to do any error handling in Lua." HAHAHHAHAAHAHA

They wrote that before seeing my code.

[bronze yoke]

the error handler literally doesn't care if you pcall and shows a red error to the user anyway, and for some reason they made all function calls protected so all pcall does is double the overhead

you'll notice errors don't propagate upwards in pz

[silent zealot]

I guess that means the lua calls made from java are already pcalls (or equivalent)

[bronze yoke]

pcall is useful in the very niche case where you specifically want to get the error since that part still works

i hate exceptions anyway so it's not a big deal to me

[silent zealot]

Just have to add "if foo~= nil" checks everywhere.

[bronze yoke]

and errors not propagating upwards by default is pretty merciful since otherwise mod errors would be way more brutal

[silent zealot]

since something being nil instead of what I want it to be is probably 98% of the lua errors I generate at runtime.

[bronze yoke]

i'd say nil checking is a better solution than try/catch blocks

but you can technically do this with pcall if you're crazy

[drifting ore]

does zomboid make other player data inaccessible beyond a certain distance (or does the client unload the player)? I'm trying to make a player compass mod for something like manhunts, but beyond 100 tiles from another player, their position stops updating and stays fixed at their last "close enough" position.

[silent zealot]

Good question - how is your code getting triggered, and how are you checking the player location?

Since the server has to know all the players I'd expect attaching to an event like EveryTenMinutes and recording player location should work, though I'm not sure how to share that with clients.

[drifting ore]

It's through the context menu on a specific item, which then populates with submenus for each player:

-- all hooked to OnPreFillInventoryObjectContextMenu
local onlinePlayers = getOnlinePlayers()

for j = 0, onlinePlayers:size() - 1 do
    local p = onlinePlayers:get(j)
    subMenu:addOption(p:getForname(), p, findPlayer, p)
end

findPlayer then gets their position like so:

target = player:getForname()
targetPosX = player:getX()
targetPosY = player:getY()
ourPosX = getPlayer():getX()
ourPosY = getPlayer():getY()

distance = math.abs(math.sqrt(math.pow(ourPosX - targetPosX,2) + math.pow(ourPosY - targetPosY,2)))
angle = math.atan2(ourPosY - targetPosY, ourPosX - targetPosX)

[silent zealot]

I'll defer to anyone with more mulitplayer modding experience.

[copper abyss]

can anybody help me out real quick?

I added a ammo type to my game, but I want two bullets to give my modded gun 20 shots, anybody know how this can be done simply?

[silent zealot]

You will need to do some lua scripting

The default is every bullet item becomes one bullet in the gun

[hexed timber]

Hey guys, im having issues with lua, specifically with the context:addOption

this is my code

context:addOption("Spawn a BoZo", nil, spawnBossZombie)

but i get the error on the screenshot, ive been going thru this for hours and cant seem to find the solution

[silent zealot]

If you download this mod you will see it patches pretty much everything related to putting bullets in guns, so you'll at least know where to look. https://steamcommunity.com/sharedfiles/filedetails/?id=3408420806

[blissful meteor]

Would it be possible to remove a context option when in an area? I want to remove the sledgehammer destroy option while in the redstone bunker

[vague marsh]

you can look in the wiki

https://pzwiki.net/wiki/ISContextMenu

[silent zealot]

@Kraz yes. Add your own function to the populatecontext menu, check if "Destroy" is a existing context menu entry, do you check and choose to remove Destroy if appropriate.

[hexed timber]

isnt this for adding a new UI? im just adding an option to the right click menu

[vague marsh]

thats already it

[silent zealot]

You're using ISContextMenu:addOption(), thats one of the things on that wiki page

[hexed timber]

Ok ill be going through it, thanks

[silent zealot]

@Kraz see Removing options on the same wiki page

[random finch]

Given an ItemContainer as parameter, I want to find the outer most container it is contained within so I can get its location aka square.

ItemContainer:getParent() always return nil with backpacks. This works with moveable and player inventories, but not for item inventories such as backpacks.

Any ideas on how to get the location of a backpack?

[silent zealot]

@copper abyss ISReloadWeaponAction:loadAmmo() is the function you want to look at, particularly self.gun:setCurrentAmmoCount(self.gun:getCurrentAmmoCount() + 1);

Add a prefix patch to the function that adds an extra 9 bullets if the weapon type is your gun.

(with safety checks to not overfill)

[blissful meteor]

Thanks I had a look, is there a similar page that details how to get the players location

[copper abyss]

AWESOME

ty so much

I know its a strange request

[blissful meteor]

Sorry I'm barebones in lua

[copper abyss]

but my modded gun is also- very strange

[silent zealot]

What sort of gun is it? We've had discussions of very weird gun ideas here before.

[silent zealot]

Nice.

[copper abyss]

welll its a fictional firearm that I'm suprised hasn't been made yet for this zombie game lol

[vague marsh]

theres a gun like that on a b41 map mod, i forgot what it is

[silent zealot]

Do you mean which slot it is equipped in?

back/fannypackfront/primaryhand/etc?

[vague marsh]

tho its not lootable, only can be spawned through debug

[random finch]

No, location, as in game world xyx or square object its on.

[silent zealot]

Only thing I'm sure of is you first check if it is equipped and if so use player location, if not equipped... not sure. Likely something to do with the square it is on.

what does getSquare() give you?

[random finch]

Backpack within another backpack or within a moveable container. Backpack on a floor is still within a container.

I thought Id be able to get its square location by using ItemContainer:getParent():getSquare() like you can everything else.

[silent zealot]

That would be too easy.

[random finch]

it doesnt inherit that method

https://projectzomboid.com/modding/zombie/inventory/ItemContainer.html#getContainerPosition()

[silent zealot]

https://demiurgequantified.github.io/ProjectZomboidJavaDocs/zombie/inventory/ItemContainer.html#getSquare()

[tacit pebble]

B41?

[silent zealot]

But that's B42, because I forget there is still B41

[random finch]

Yup, working on a MP project

Damn, you get access to that in B42 at least.

[tacit pebble]

yeah then there's no getSquare I believe

   public IsoGridSquare getSquare() {
      IsoGridSquare var1 = null;
      ItemContainer var2 = this.getOutermostContainer();
      if (var2.getVehiclePart() != null && var2.getVehiclePart().getVehicle() != null) {
         var1 = var2.getVehiclePart().getVehicle().getSquare();
      }

      if (var1 == null && var2.getSourceGrid() != null) {
         var1 = var2.getSourceGrid();
      } else if (var1 == null && var2.getParent() != null && var2.getParent().getSquare() != null) {
         var1 = var2.getParent().getSquare();
      } else if (var1 == null
         && var2.getContainingItem() != null
         && var2.getContainingItem().getWorldItem() != null
         && var2.getContainingItem().getWorldItem().getSquare() != null) {
         var1 = var2.getContainingItem().getWorldItem().getSquare();
      }

      return var1;
   }

this is getSquare() for inventoryContainer since B42

[silent zealot]

A horribel idea: what if in B41 the square stores containers, but those containers have no link to the square?

[tacit pebble]

maybe you can tweak that for B41?

[random finch]

Ill have to itterate through each square to find the container lol

[silent zealot]

So all you can do is test every square in existence?

which is... not a good idea.

[random finch]

hrmmm

[hexed timber]

ok made it work, now im having issues with local zombies = getWorld():addZombiesInOutfit(1, x, y, z, nil, false, nil)

I basically need to spawn a zombie, to later alter its attributes, thats the spawn line, it just jumps an error with no stacktrace

[tacit pebble]

I don't think you need getWorld() for addZombiesInOutfit

[hexed timber]

ill try this

Ok it does spawn it, but how do i access it after it?

[tacit pebble]

what do you mean access it? do you want to get list?

[hexed timber]

yes, im trying to alter its HP and other values

[random finch]

Could you please send me getOutermostContainer as well? I havent decompiled B42 yet.

[tacit pebble]

addZombiesInOutfit will spawn zombies but also return zombie list which you spawned.

[tacit pebble]

oops I was trying but forgot suddenly sure

[hexed timber]

Yeah, im getting and error prompt here local zombies = addZombiesInOutfit(x, y, z, 1, nil, 0)

let me get the exact error

[tacit pebble]

   public ItemContainer getOutermostContainer() {
      if (this.getContainingItem() != null && this.getContainingItem().getContainer() != null) {

         while (var1.getContainingItem() != null && var1.getContainingItem().getContainer() != null) {
            var1 = var1.getContainingItem().getContainer();
         }

         return var1;
      } else {
         return this;

[sturdy salmon]

Hello, good evening, I was trying to keep a record of the vehicles, but I noticed that the methods I am using, in both cases, change the value when the chunk is reloaded. The getID is supposed to change, but the strange thing is that the getSqlID also changes (when it is supposed to refer to the database ID). I don't know how to identify them, in case I lose any. Any suggestions? Thanks in advance for reading.

• https://projectzomboid.com/modding/zombie/vehicles/BaseVehicle.html#getId()
• https://projectzomboid.com/modding/zombie/vehicles/BaseVehicle.html#getSqlId()
  I am on build 41.78.16

The strange thing is that it seems to add 10. Because it is clear how it says 11, and then 21. How it says 13 and then 23. I had not noticed that. But well, maybe those are not the methods I have to use, and on the contrary, there is another way to identify them.

[elfin cobalt]

Dude imagine if there was a mod where you couldn't see the percentage of batteries and you need a battery checker to check the percent 🤔 (this is a mod suggestion :3)

And make batteries spawn in with random charge levels

[sturdy salmon]

There is a sqlite3 database for vehicles. Finally, vehicles, in that DB at least, have an ID.
The strange thing is that the method called getSqlId() returns different results.

[sturdy salmon]

The method to access the battery exists. https://projectzomboid.com/modding/zombie/vehicles/BaseVehicle.html#getBattery(), however, it returns a VehiclePart. Then you have to identify the battery. Although you would have to check (perhaps), that the battery is installed, because if it is not, I don't know what could happen.

If I remember correctly, the VehiclePart can be accessed by index, but I don't know exactly which battery it is.

[elfin cobalt]

Not the vehicle batteries, the small ones.

Double A

[sturdy salmon]

We differentiate them, but I see that they have the same name.

[sturdy salmon]

The getKeyId() method seems to always return a unique value.

I will have to use the method to identify the vehicles for now.

[bright fog]

You can store zombies in a variable when spawning them in

[copper abyss]

heyyy.

alittle confused here

I cant get it to work

[bright fog]

I'd suggest checking the various vehicle fields and also classes which are linked to that vehicle, check if they are persistent. The fields might have some stats or data of the vehicle which is persistent

Also

Are vehicles object pooled ? If not then the vehicle keeps the same class on reload

If so you can just do tostring(vehicle) and you will have an ID

Tho I doubt it tbf but who knows

[sturdy salmon]

I'll try it. But at the moment, the only value that seems to persist is the key value. But I'll see what you tell me. Thanks.

[bright fog]

[sturdy salmon]

[2025-02-26 08:12:55] player: Pango. TP: /teleportto 12063,6874,0. vehicleGetFullName: Base.SmallCar. getKeyId: 97884626. vehicleGetEngineQuality: 34.

[silent zealot]

does getKeyId() give a unique, persistent result? I assume it's related to car keys matching up to cars.

Using modData to make your own unique identifier should also work.

[sturdy salmon]

Apparently. At least it is more accurate than the other 2 methods so far. I will have to test it.

[sturdy salmon]

Do you have any examples of that? I'd like to see it. Or any mods that use it.

[silent zealot]

Have yo done lua scripting before? What you want will need some lua code, since it's not possibel through just item configuration.

[copper abyss]

just alittle, this is the most I could really do, it works but- the reload wont happen for awhile unless the player presses shift, sometimes it breaks entirely.

it focuses LESS on the TYPE of ammo, and more on the actual gun

problem is, if I do it this way- it will only add +18 once the MaxAmmo is reached

[silent zealot]

Also, you're replacing vanilla functions so you're going to break other guns.

[copper abyss]

😭

[random finch]

Might be some confusion, I am hooking ISInventoryTransferAction:isValid() where you can pull the source and destination containers.

I am having problems getting the square an ItemContainer is located in when it is an item container such as a backpack.

[silent zealot]

It's OK, writing code that doesn't work is how you start writing code that mostly works.

[sturdy salmon]

Would it be possible to turn this channel into a forum? So that each topic is a thread. That way the conversations are kept separate. I think that would be a good idea, so that we can collaborate better.

[tacit pebble]

idk how can i say this in english :/

[silent zealot]

First of all - does your gun have an item defined as bullet, and without any extra lua code does that thing get loaded in one-by-one when you press reload?

[copper abyss]

yes! I made a custom ammotype "Cold Cell Battery"

[copper abyss]

and also yes

[tacit pebble]

The gun says it has 2 bullets, but

Does this mean you can actually shoot 20 times?

[copper abyss]

indeed, I want the gun to consume 2 bullets, but have a max capacity of 20

[silent zealot]

no, we're not there yet - rember in vanilla one bullet = one shot

I thought you wanted one bullet to restore 10 shots when loaded in?

[copper abyss]

yes 10 per cell, but 20 max capacity

2 x 10

2 cells consumed

problem is, whenever I try to code it so that it focuses on the ammotype, instead of the max capacity, the gun doesn't consume 2 cells, and instead just adds the amount of ammo I want if I have atleast 1 cell in my inventory

and irregardless of the way I go about it, whenever the gun is unloaded you end up extracting the current ammo amount that is in the gun..

so if you insert 2, you get 20 in the gun, unload the gun, and now you have 20 in your inventory lol
