Even models reload automatically

AnimSets, animations

Scripts we can hot reload them now apparently tho I haven't looked at it

Sounds I think you need to restart

[frank elbow]

I have no idea whether it actually works because I've never used it, but you can right click object fields & there's a context menu

[bronze yoke]

oh man, i never tried that 😅

that's super useful if it works

[bright fog]

What does that do ?

[frank elbow]

In theory, adds fields to a window that displays the value

[lost chasm]

the fact that the debug configuration is the same interface as the context menu ingame is hilarious

Can't be the only one who thinkgs that, can I? xD

[bronze yoke]

presumably you can see the value of that field no matter what part of the code you're in, and get breakpoints when that field is written to/read from

[bronze yoke]

if i remember right there's a blog post explaining that the debugger was made ten years ago in a week with a lot of alcohol involved

[lost chasm]

amazing

it had to be hilarious then, there was no other option

[bright fog]

Explains the shitiness of it I guess

[bronze yoke]

you really have to git it a chance 😅

[bright fog]

I DID !

THAT'S WHAT I KEEP TELLING YOU

I keep trying to use it !

I keep trying it !

And I just cannot figure out how to navigate it !

[lost chasm]

is it updated or maintained still? or has it been untouched for 10 years? xD

[frank elbow]

Step into, step over, continue

[bright fog]

None of the windows placement makes sense or it's completely unclear what these even show and they don't even show what I expect them to see

[bronze yoke]

well, it still works; it's not like the language has changed so i guess it doesn't need much maintanence

[bright fog]

Damn you think that's the thing that blocks me lmao ?

[frank elbow]

Heck if I know lol

[bronze yoke]

sometimes trying to inspect objects throws errors but it's not like everything crashes when that happens

[bright fog]

You want me to start using this piece of shit and praising it ? Make a guide for it!

[lost chasm]

oh, are there no guides for it?

[frank elbow]

From a very quick check it seems the watch window is not all that reliable, but that's from testing exiting and re-entering the debugger

Maybe it works better when actually stepping through code

[bright fog]

Be aware that the modding wiki dates from december 2024 for the majority of the stuff you can find on it currently

[lost chasm]

but the debugger has 10 years! Far more than enough time for someone to make a guide for it

x_D

[frank elbow]

I don't know that it warrants a guide beyond labeling the things that are in it (& maybe how to get to it since people probably don't think to hit F11), but things are already labeled

If you have prior experience with a debugger it's pretty much just a barebones version of a normal one

[bronze yoke]

yeah, well doggy is more or less the only person seriously working on the modding side of the wiki so if he doesn't use it it's not likely to be on there 😅

[lost chasm]

a guide makes everything easier and helps lots of people. Obviously most experienced people wont need it but, its always a good thing to bring to the world

[bright fog]

Exactly, I'd love to tell about it, I'd love to manage to use it, trust me

But I just cannot figure out, and in 2 months I'll try again, realize that anything that I expect to be right clickable actually isn't and that none of the windows can be moved around, adding to my confusion of navigating this shit, there's no going back button or idk what, there's nothing to allows me to properly navigate the whole UI

And I'm just completely lost

So until someone shows me in real time a complete usage example and how to navigate this crap, I just can't write anything about it

[bronze yoke]

if somebody sends a screenshot of the debugger i can point out the basic usage

[lost chasm]

@swift loom and @frank elbow , you make this sound easy. Why dont you show him in a short discord call? sounds like a good evening time xD

[bright fog]

Yea that's what I don't get, that it looks easy to them and I just can't figure it out lol

[frank elbow]

I'll send a screenshot in a moment, but letting you know it'll be from b41 in case anything has changed (I don't remember there being changes, but pointing that out regardless)

[lost chasm]

oh man, my spacebar is starting to show signs of death. This is not what I was expecting the day I convinced myself to learn this xD

[bright fog]

jesus

Tho most of these I kind of knew, I just have issues navigating the whole UI overall

But I'll note it down and next time I end up with a potential usage of the debugger I'll try AGAIN

[tranquil reef]

Anyone know the max item displayname length

[bright fog]

Good question

[bright fog]

If you find out I'm interested

[spring ice]

Hi, I wanted to know if there is a script or some kind of database were all the "FootstepMaterial" values are located

Is a Property of IsoGridSquare

[knotty path]

does anyone know how to change the text that displays when you right click? For example, if you want to change the text about dismantling a cabinet from "dismantle" to "destroy"?

[vital sedge]

any way in lua to get what procedural list was used when filling container ie. container is crate and then what proc list was chosen like CrateFitnessWeights, CrateTools or CrateCanning?

[supple briar]

so, question, can we make new vehicle scenes in B42, and how does spawning work for those?

The fear is setting in that I might actually need to learn useful coding skills like Lua to make what I want work

[steady fable]

@silent zealot HEY!

I think one of the updates you did to the easydistro mod broke alot of my subscribers saves.

[silent zealot]

What update, and broken in what way?

[steady fable]

The one yesterday at 5 AM EST.

I've had complaints since then, though I directed them to subscribe to your mod. It looks fine on my end.

[bright fog]

Do you use his API ?

[steady fable]

I do, yes

Its a critical dependancy of box more now

[bronze yoke]

it's because you added a dependency

the game won't load a mod without its dependencies, and nothing makes them automatically get the dependency mod/enable it on that save

[steady fable]

yeah that is problematic

I'll have to add a warning on the mod.info then.

[bright fog]

Not a warning

Just a straight up require

So activating your mods requires the dependency mods

Also when adding a new dependency in your mods, make sure to announce it everywhere on your modpage

Comments, patch note + description

[bronze yoke]

the require is the problem

because it's required the mod no longer loads for anyone who doesn't already have it, which is probably everyone

i also don't think it'll load for people who do have it unless they already had it enabled on that save

you don't really want to add requirements after a mod's release if you can avoid it

[balmy ore]

Anyone know if there’s a timeline for Brita’s?

[bright fog]

Just properly announce it

[bright fog]

?

Timeline ?

Like when it releases for B42 ?

No idea

[bronze yoke]

doesn't really matter how well you announce it, plenty of people will get in-game without seeing it

most even

it'll stop the mod from loading, which will permanently remove every item, tile, etc from your mod from their save

[bright fog]

Yes, but then they'll see something is wrong for the majority of them so they check the mod page

So if you properly announce it you won't get any issues

I've done that multiple times already without any problems

I've never gotten a single comment saying they got issues, bcs I wrote a big ass comment in header format saying there's a ndw dependency

[bronze yoke]

because your mods don't add very many items or tiles right?

[bright fog]

How would that stop those. Scripts are independent from Lua files ?

[bronze yoke]

the mod doesn't load whatsoever if the dependency is not enabled

it will be as if the mod isn't even enabled

[bright fog]

Tbf, I wouldn't give a shit anyway

[bronze yoke]

they just have to reenable the mod and it's fine, but for item + tile mods it permanently damages the save file of more or less everyone who uses the mod, to the extent that they might want to start over their save entirely - people will be really pissed in this case, and it's kind of justifiable

[bright fog]

Embrace the chaos 8)

[bronze yoke]

if you remember the kind of harrassment honesty received a few months ago for a way less serious issue it's really not worth it

[bright fog]

He caused it actually, he meant to do that

[bronze yoke]

that's not what he said

he came into the modding discord and said that he hadn't meant to make people's saves unplayable (and it is kind of unintuitive that it does that)

[bright fog]

I talked with him in vc, and he stated multiple times that he decided to nuke them

He was proud of it at least

[bronze yoke]

he wanted to remove the map permanently but did he really say that he intended to brick every save file using the map?

[bright fog]

Maybe a change of state of mind ?

[bright fog]

Yea it really sounded like that

[bronze yoke]

well if he was just lying about it being accidental then i'm kind of mad at him again 😅

not that the sheer level of harrassment he received was justifiable either way

[bright fog]

Idk tbf, I get the desire to give a lesson to mod users

Kind of extreme, but I get it

That's why he stated he meant it, because he was annoyed at mod users complaining

[bronze yoke]

if it really was intentional then i think it was really stupid of him but it didn't sound like it was when he spoke about it

[bright fog]

Guess we got two different story 😅

Stupid ? Perhaps. Kind of feels nice to show them you don't owe them anything tho

[bronze yoke]

it didn't sound like he came out of the situation 'feeling nice' though 😅

[bright fog]

That can definitely be understandable at the time with the amount of hate you receive

[supple briar]

I think purposely bricking people's saves to "teach them a lesson" is well beyond the level of stupid

[silent zealot]

You could leave out the dependency in mod.info, detect if the mod is active and have a pop up window on every game start saying "WARNING: you have until June 30 to subscribe and enable Easy Distro and if you do not all your boxes will vanish! Until then, no boxes will spawn in the world."

People will still complain though. Because they are people.

[silent zealot]

I think they want the new firearm system to be stable before they start to port their "we changed everything about guns" code over.

Personally I think they should cut back on the bloated feature list in their framework, and just start with "here are all the guns in B42 with vanilla-style features"

[balmy ore]

That makes a lot of sense lol

[balmy ore]

There is a lot of stuff in that mod lol

[silent zealot]

I never used any of it other than the different magazine sizes, and that wouldn't be hard to do (having looked around while letting the survival rifle use two calibres automatically)

Their armour pack would be easy but time consuming to port to B42.

So many items, lots of tweaks to better work on B42 (tags, discomfort, etc) and all recipes need to be redone.

[silent zealot]

Which mod was that?

[bronze yoke]

it was a map mod

he removed it from the workshop, but you can't remove maps from a save, nor can you launch the save without them, so it bricked every save using the mod

it was a really major drama, he received a crazy amount of harrassment over it

[supple briar]

Funnily enough, a while ago I was working on a mod that was basically that, a purely vanilla gun pack

[silent zealot]

You can, but it involves fiddling around with the save file in a way most people are unlikely to be comfortable with.

[bronze yoke]

well yeah, you can do anything, but it's not something the game just lets you do

[silent zealot]

I've had fun releasing a few guns that are distinct from Rain's Gun Pack, which I feel is a good collection of weapons to expand the limited range in vanilla without being excessive.

With the new fluid system it's finally possible to make a vickers water-cooled machine gun.

[supple briar]

My idea was basically a light version of something like Brita's or Rain's. No new systems but I think at its peak my gun idea list was nearing 100

[bleak mortar]

im trying to make a trap give me a dead deer, whats the name for a dead deer types?

[silent zealot]

Looking through the britas weapon list, so many redundant weapons in there.

[silent zealot]

Trapping now trap live animals.

I'm not sure if you can get it to do dead ones anymore

[bleak mortar]

im aware, its just that they run off

[silent zealot]

(without coding your own variation)

[bleak mortar]

i think i might be able to depending on if i can find the name of the deer corpse

[supple briar]

My list was basically all redundancy
For Example you had: The M16, M16A1, XM16E1, The Colt SP1, M16A2, and then variants and civilian versions.

[bleak mortar]

just dont know where i would find it in the items list

[silent zealot]

A better option would probably to be to hook the "check trap" function and kill the deer after it is spawned in the world

dead animals are weird not-quite-items

[bleak mortar]

i aint that good at coding lol but i can try

[silent zealot]

When I had a look a while ago I couldn't see an easy "dead animal item" to spawn

[bleak mortar]

yeah me neither, where would i look to find the check trap ui interaction

[silent zealot]

One approach: you know it says "check trap" on the context menu so you search for that knowing it will be in the translation files: ContextMenu_Check_Trap = "Check Trap",

then search for ContextMenu_Check_Trap which has one hit in a fish net thing and one in ISTrapMenu.doTrapMenu() in media\lua\server\Traps\ISUI\ISTrapMenu.lua

that leads you to ISTrapMenu.onCheckTrap, which leads you to the timed action ISCheckTrapAction

and the timed action will do somethingin the :complete() step

[bleak mortar]

i will put this together, you have been a great help, i greatly appretiate that.

[tranquil reef]

Is there a way to see if my distributions script is working without teleporting around and checking crates

[silent zealot]

yes

cheats -> enable lootzed

right click a container in the inventory view, LootZed

You can see what can spawn in it.

[tranquil reef]

Ah, thank you.

[silent zealot]

Note: this tool reads the lua distribution table, if you change that the normal way (i.e. when the lua script is loaded) this is fine but if you do something fancy later on you need to re-sync the lua and java loot tables.

the cheats -> item picker will also indicate if an item is in any loot tables (one of the columsn on the right side, at least in B42)

[silent zealot]

I might have an even easier way: try setting deer.canBeAlive to false in the TrapAnimals settings

May need to make a DeadDeer item, like the existing Deadrabbit etc items

[bleak mortar]

yeah thats what i was trying to find out what the item was called for a deer corpse

[silent zealot]

Wait, that was meant for @bleak mortar

[tranquil reef]

I was gonna say lol

[silent zealot]

Sorry!

I blame flu

[bleak mortar]

i just dont know where to look for that item name

if i can find it i can code it easily

[silent zealot]

I use VSCode, open the games media directory

makes searching very quick

[bleak mortar]

theres a search function?

[silent zealot]

A really fast one!

I keep a VSCode open with media and zombie (decompiled java) as a reference.

Can add other mods in if I want to include them too:

[bleak mortar]

ill have to come back to this later but i appretiate all your help man, incredibly thoughtful and kind, but right now my freind is wanting to play with me so ill have to put my mod on hold.

[supple briar]

So it turns out PZ already has a Racecar spawn zone at Irvington, it's just unused due to the game lacking Racecars

[silent zealot]

If only someone was making a mod to add racecars....

[supple briar]

Yeah if only

gotta figure out how to use them now

So here's what I can see, racecar/parkingstall, but I can't find a racecar zone in the vehicle zone defs

got em working now

So the only issue is that it covers every parking stall in the race track, which while not much, does cause some issues

not many though

I want to let guns be dismantled into Base.Reinforcement_Points. The number of Reinforcement Points received should be based on the gun’s metalValue : you get 1 Reinforcement Point for every 5 metalValue, with remainders of 2 rounded down and 3 rounded up.

Been deep in the wells of GLSL shaders. I am working on making a UI framework around them. Here is my progress from the past week of free time:

3D transforms with parent-child UI elements, borders, rounded-border settings, colors, and a rewrite of the game's font renderer so that they can be transformed in 3D space.

HTML / CSS-like rendering is possible in PZ UI using GLSL shaders.

This next week I'll work on getting a functioning layout tree where things like z-index CSS rules and width / height rules will be taken into account.

If that's done I'll work on pagination for things like <textarea> or <p> elements.

[silent zealot]

Don't trust chat GPT. Did it write the code, or did you write it then used it to help troubleshoot?

I hate embedding function definitions in a function call like that, I find it makes it a lot harder to troubleshoot (it is a valid thing to do, I just hate it!)

Also, what errors are you getting?

[silent zealot]

Is there a way to go from an ISO location to a screen location, or from a 3d model to a 3d model? For example, if I made a laser gun and wanted to draw a line from the gun model to a target

I'm not sure if that is completely outside the scope of shaders or not

They seem to do almost everything, instead of just shading as the name implies

#mod_development message

My response to a previous "fix this AI code" request

Look at line 14, look at what function of actualitem you're calling, think about why it is nil interest of a valid function

Most likely actualitem is nil or the AI made up a function call that does not exist. Because AI does that. A lot.

Remember large language models are for text, not code. And with text it's fine to use a slightly different word or phrase things a little differently, but in code it is not.

Check this out for more detail

[vital sedge]

is this faster than total commander?

[silent zealot]

I don't use that,. so I don't know how long it takes.

Searching feels near-instant

[opal temple]

Oh, I modified line 14. I saw someone else write something like this before, so I used it:

local inv = player:getInventory();
  inv:AddItem("DLTS.LTSCharcoalPowder");
  inv:AddItem("NoLS.Rubber");
end

I’m sorry, I really can’t come up with a solution… Could you please show me a correct example so I can work backwards to find the issue?

[silent zealot]

example of adding something to right click context menu:

local doDIYContextMenu = function(playerNum, context, items)
    print("##### doDIYContextMenu()")
    local primaryItem = items[1]
    if not instanceof(primaryItem, "InventoryItem") then
        primaryItem = primaryItem.items[1]
    end

    if primaryItem:hasTag("DIYSchematic") then
        print("##### It's a DIY Scematic")
        local playerObj = getSpecificPlayer(playerNum)
        readOption = context:addOption(getText("ContextMenu_ReadDIY"), items, DIYonLiteratureItems, playerObj);
    end
end

Events.OnFillInventoryObjectContextMenu.Add(doDIYContextMenu)

Then the function DIYonLiteratureItems is what gets called by the context menu option that was added

I'm not sure what you're trying to do with adding CharcoalPowder and Rubber to the player inventory before an end statement that doesn't match up to anything, or why that is relevant.

[silent zealot]

There's a B42 Repair Anything mod

Rip Anything is a problem because if you can't programmaticly add tags then they are ignored by the recipe system, which has already decided which recipes affect which items and it doesn't re-check. Might be away to force it to refresh, but I've not looked hard for that.

[vital sedge]

@silent zealot i see you know a lot about code, especially java one, am i right that you can't get information about chosen procList for the container, from any lua function?

[opal temple]

I tried changing it to this, and there are no errors. It feels really interesting—thank you so much.

local GetReinforcementPoints = function(playerNum, context, items)
    print("##### GetReinforcementPoints()")
    local primaryItem = items[1]
    if not instanceof(primaryItem, "InventoryItem") then
        primaryItem = primaryItem.items[1]
    end

    if primaryItem:hasTag("Firearm") then
        print("##### It's a DIY Schematic")
        local playerObj = getSpecificPlayer(playerNum)
        readOption = context:addOption(getText("ContextMenu_GetReinforcementPoints"), items, DIYonLiteratureItems, playerObj);
    else
        print("##### It's not a DIY Schematic")
    end
end

Events.OnFillInventoryObjectContextMenu.Add(GetReinforcementPoints)

Next, I’ll try to add functionality to the menu…

[silent zealot]

That is going to call DIYonLiteratureItems() which will fail

That code is just for adding the contect menu option. Then it calls a function when that option is selected.

Instead of DIYonLiteratureItems, you need it to be calling a function that turns guns into your reincforcement items.

Speaking of which , you need to make the item definitions for those if you have not already done so.

[opal temple]

I’ve been thinking for a long time and still don’t know where to start. I’ve been awake for nearly 24 hours and feel a bit dizzy. Could you please help me once more and give me a few more hints? Oh, the items are already defined.

[red tiger]

Computational Anti-Aliasing is a thing yeah.

I'm more concerned right now with getting the maths right first.

It'll be interesting getting anti-aliasing working for this:

It's nice to be able to take all the normal operations for these sorts of things and then apply it in a 3D space as well.

[silent zealot]

You've told the game "add an entry to the context menu when I right click on the firearm"

But you havn't told it what to do when you select that entry.

[red tiger]

@silent zealot Sorry wrong reply.

@slim swan Above was for you on the modding discord.

[silent zealot]

Also, get some sleep. 😛

[silent zealot]

"Computational Anti-Aliasing" as a way of converting from 2d to 3d is a very odd name, but it wouldn't be teh first time in computing that something has a nonsensical name.

[red tiger]

No that's not what I mean't. There're two statements in that.

I'm simply happy to have a solution where I can use proper matrix transforms to augment what is traditionally painted in 2D space in 3D.

[silent zealot]

That is helpful

[red tiger]

Computational Anti-Aliasing was for Rocco.

And it's not nonsensical. It's actual practice.

[silent zealot]

yes, but probably not for what I asked about.

[red tiger]

Render-Shader passes are for more proper anti-aliasing techniques. Because I'm doing more hackish ways to get shading working, I don't have this option.

[red tiger]

Nope.

[silent zealot]

TurboEncabulator.ReticulateSplines()

I wonder if we can repeat that often enough that AI starts to pick it up 🤣

[slim swan]

I’ve already thought of many QoL mods that could be built using this framework.

[red tiger]

What I want to see are inventory mods.

[slim swan]

For example, when I’m near a campfire or fireplace, it could directly display the remaining time or fuel amount.

[red tiger]

Here was my hardcoded tech demo of shaders being used:

It's building up a proper API and framework to get that to be streamlined in a mod production sense.

Imagine having menus like floating cards that can "fall away" when disabled.

There's a lot of potential here.

If people can look at the 3d models that closely they are going to realize how terrible they are lol

[red tiger]

Like a good example would be say a card-game mod.

[silent zealot]

But it is a great dvelopment in potential UI uses

[red tiger]

Dynamic and modular shaders takes time and testing / adjustments to make unfortunately but I think it's worth the time.

I could quickly make hardcoded UI for my own needs but I don't think this community has many rendering programmers. =)

[silent zealot]

I suspect this community has one, and it's you.

[red tiger]

There's a few for sure.

Might tickle them into talking when seeing this stuff.

[silent zealot]

We do have lots of people that coudl learn if motivated.

[red tiger]

I think it'd be fun to write a shader UI + mod that emulates old MsDOS computers from the 90's.

[opal temple]

I tried writing a block of code, but it still throws an error. I think the problem is with getTag("MetalValue").
I can't stay up any longer — I'll continue trying after I wake up.
Good night, fellow survivors...

function DIYonLiteratureItems(playerObj, items)
    local MetalValue = getTag("MetalValue")
    local points = (MetalValue / 5)
    local inv = player:getInventory();
            if points > 0 then
                inv:AddItem("Base.Reinforcement_Points", points);
                player:getInventory():Remove(primaryItem)
                player:Say("IGUI_Get" .. points .. "IGUI_Points")
            else
                player:Say("IGUI_CantBreakDown")
            end
        
    
end

[silent zealot]

You should really give the function a more appropriate name instead of copying the example name from DIY literature code

Also, that looks like AI generated code.

It makes no sense.

[silent zealot]

It's made up a whole new way of using metalValue that doesn't work

[silent zealot]

My guess would be one of A) don't put functions that don't exist in recipes or B) figure out why those functions do not exist

[neon palm]

Like I don’t know which mod that is

[silent zealot]

[VFE] is a pretty big hint

[neon palm]

Ok

[silent zealot]

As are references to "craft silencer" and "make 5.7x28mm"

[opal temple]

I don’t know how to get the MetalValue parameter. Earlier I saw you used hasTag, so I thought maybe it’s getTag.
I did use the previous code because I really don’t know how to write it correctly 😦

[silent zealot]

Vanilla firearms expanded probably, if not it's something else to do with firearms

[silent zealot]

You can't make a random guess, give up when it doesn't work, and ask other people to do the work for you

Lookup "Zomboid javadocs" and see what functions exist when you search for "metalValue"

There is probably a function for InventoryItem objects to get the metal value as a number

[bright fog]

getTag is not a global function

[bright fog]

Show the code

[silent zealot]

Another good point lol

[bright fog]

https://pzwiki.net/wiki/JavaDocs

[silent zealot]

I'm not even sure if there is a getTag. There is getTags and hasTag

[bright fog]

@opal temple @neon palm both of you check this link

[bright fog]

Yea I thought about it

Tho no idea, I'd have to check the java doc

[frank elbow]

@neon palm may be looking for #mod_support given the message before the errors

(I see now that they have a message there already)

[opal temple]

Oh, you’re my hero. It’s getType, right?

[opal temple]

I had no idea such a thing existed before. I’ve always wondered how everyone knows about these things and how to use them.

[neon palm]

Where?

[bright fog]

You want the metal value ?

Then no that's not it

[frank elbow]

If you're asking which message I'm referring to, I mean the text in your message prior to the error text

i.e., it implied you were not developing a mod but were instead having mod problems

[bright fog]

Can you give more info ? That's in B42 ? That's a crafting function ?

[opal temple]

Yes, this is B42.

It determines how many items to give based on the firearm’s metal value.

[bright fog]

I'm fairly certain the metal value does not vary

I remember it just being for metal or 0 for non metalic or some shit like that

Did you check if it's different for different firearms ?

[opal temple]

I saw that the Firearm mod gives guns this attribute, so I used it accordingly.

[bright fog]

What about vanilla weapons ?

You can't base yourself on mods for codes unless you're making an addon for one, which I would guess in your case you're not ?

[opal temple]

It also has it.
item AssaultRifle2

local MetalValue = primaryItem:getMetalValue()

[bright fog]

But does it vary between each firearms

[opal temple]

I'm not sure about that, but I can set it on my firearms and then disassemble them based on that value.

[silent zealot]

Rifles are 45, pistols are 30 and when you cut down the barrel of a JS-2000 you remove 10 units of metal. But cutting down the barrels on a double barreled shotgun doesn't remove any metal at all.

So, typical zomboid accuracy. 😛

[tranquil reef]

Anyone know if vomiting was planned and scrapped, or if its still planned

There's an animation for it, but I've never heard anything else about it

[bright fog]

Nice

[frank elbow]

Only mention I could find is https://projectzomboid.com/blog/news/2016/03/re-animator, which suggests to me that it was just something added as an animation among many that might've been useful at the time

[tranquil reef]

2016, damn

holy shit, 9 years ago

well, guess I don't have to worry about them releasing the mechanic a day after I release my mod lol

[silent zealot]

I guess it's there if someone wants to mod in vomiting

[silent zealot]

If you're adding vomiting remember to check for the CanEat tag on any facewear, and if it's not set... well that's really bad.

Instant max discomfort meter

[mossy steeple]

howdy- has anyone here happened to look into how the new jog-bumping mechanics work? i've been looking to revert it back to the previous b42.7 behaviour but unfortunately i'm quite a novice modder and haven't been able to figure it out myself.

not totally sure where that is in the game files, or if it's even easily modifiable

[bright fog]

New jog bumping ?

What is it ?

[mossy steeple]

the random turn your character does when you bump into zombies- it feels really bad because it doesn't just shunt you to the side, it actively changes your direction which then forces you into the turn-around animation to move in the direction you were already holding

also it doesn't turn you if you do it while using the walk-to command

[bright fog]

Ooooh is that the shit that's happening with zombie lunges pushing you in random directions ?

[mossy steeple]

i think it's different but it feels very similar to that, imo

[bright fog]

No someone was talking about the game randomly changing your direction

It's not the thing where if you aim your character can end up rotating around and being terribly placed

[mossy steeple]

• getting knocked back, even falling over from a lunge? cool, that's fine, makes it risky if you're ill-prepared
• getting knocked back and randomly turning a full 180 degrees somehow? there's the problem

[bright fog]

I think they explained it's something where the character will end up in the wrong orientation

[tranquil reef]

great idea

that's actually really helpful lol, I probably would've thought about it somewhere along the way, but I wouldn't have realized the CanEat tag would held me detect it. I probably would've made a table and tried to manually add each mask

[mossy steeple]

not familiar with what you're mentioning myself, unfortunately

the random turns i mean, not the caneat tag stuff

[bleak mortar]

see, i tried that here, but then i get an error in a STrapGlobalObject at line 291

something here is bugging out and i have no idea why

[red tiger]

Looking smooth.

Doing pixel-padding on quad render so there's room for the AA code to breathe.

[solar rover]

SoundGain and NPCSoundBoost, what the heck are they? all I get from the wiki is DEPRECATED yet people keep adding them to the weapon mods. Any help?

[bronze yoke]

they don't do anything, people just guess when they add them to their mods

[solar rover]

(╯°□°)╯︵ ┻━┻

[bronze yoke]

don't trust other mods, most modders genuinely have no idea what's going on 😅

[solar rover]

Yeah, I'm running through CJ's firearms mod. He did a ton of work and I respect that but a lot of it looks copy/paste. VSS with subsonic rounds and built in suppressor with 130 SoundRadius 😦

Going to edit his 40-50 guns for my server before I start throwing my own stuff in.

Can I generally ignore anything listed as depreciated on the pz wiki?

[bronze yoke]

yeah, when we say 'deprecated' we actually mean 'removed' lol

[solar rover]

heheh figured

Appreciated albion

[ancient grail]

oh hey fancy seeing you here.
yeah deprecated stuff on item scripts are just bloat but its not gona do harm or anything.
game will probably just consider it as moddata
so if you want to test it then call the items moddata via lua console or use a moddata tool of some sort

[solar rover]

Yeah I figured I could test the setting I messaged you about but these two I wasnt sure how to figure out

[bronze yoke]

if they aren't recognised by the game at all they won't be on the wiki

when they're marked as deprecated that means the game does recognise and handle them, but that they just don't actually do anything

so they won't go to moddata

[untold turtle]

I need modding assistance with making custom vehicles (blood/damage overlay textures)

[solar rover]

With just how to make the textures or what?

[untold turtle]

Nah I got em all made but damage and blood textures show together when a hood is damaged for example instead of damage only

[solar rover]

Does your script look something like this

        textureLights = Vehicles/vehicle_dodgeram_lights,
        textureDamage1Overlay = Vehicles/fr_Veh_Blood_Mask,
        textureDamage2Overlay = Vehicles/fr_Veh_Blood_Hvy,
        textureDamage1Shell = Vehicles/fr_Veh_Damage1,
        textureDamage2Shell = Vehicles/fr_Veh_Damage2,
        textureRust = Vehicles/fr_Veh_Mud,

[silent zealot]

What is the error? Guessing from just a screenshot, you don't have baseHunger defined so baseHunger defaults to 0 and the next line is a divide by zero error.

Which isn't something that normally happens, because the deer woudl be generated as a live animal not a corpse item with food values assigned in that function.

[untold turtle]

My scripts look like that yea

        textureMask = Vehicles/vehicle_Humvee_Vehicle_Mask,
        textureLights = Vehicles/vehicle_Humvee_Base_Lights,
        textureDamage1Shell = Vehicles/vehicle_Humvee_Base_Damage_Mask1,
        textureDamage2Shell = Vehicles/vehicle_Humvee_Base_Damage_Mask2,
        textureDamage1Overlay = Vehicles/vehicle_Humvee_Base_Blood1,
        textureDamage2Overlay = Vehicles/vehicle_Humvee_Base_Blood2,
        textureRust = Vehicles/vehicle_Humvee_Base_Rust-Dirt,

[mellow frigate]

what should I do to ensure a custom variable added to my IsoPlayer is correctly synchronized in MP ? I use playerObj:setVariable("myFancyVariableName", true)

[opal temple]

@silent zealot
Could you please take another look and see what’s wrong?🙏
I want to show a confirmation dialog when the menu option is clicked, and only perform the dismantle action after confirming.
But right now the right‐click menu option doesn’t even appear.
I referenced the Split Items mod’s UI creation code.

local GetReinforcementPoints = function(playerNum, context, items)
    print("##### GetReinforcementPoints()")
    local firearms = {}

    for _, item in ipairs(items) do
        local actualItem = item
        if not instanceof(actualItem, "InventoryItem") then
            actualItem = actualItem.items[1]
        end
        if actualItem and actualItem:hasTag("Firearm") then
            table.insert(firearms, actualItem)
        end
    end

    if #firearms > 0 then
        local playerObj = getSpecificPlayer(playerNum)
        context:addOption(
            getText("ContextMenu_GetReinforcementPoints"),items,useConfirmUI,playerObj,firearms)

    self.__index = self
    o:setResizable(false)
    o.pin = true
    o.title = getText("UI_BreakDown_Title", items[1]:getDisplayName())
    o.player = player
    o.items = items
    o.firearms = firearms
    o.totalPoints = totalPoints

    return o
end

    self.splitButton = ISButton:new(10, 140, 135, 30, getText("UI_CA_BreakItems_Confirm"), self, useConfirmUI.onMouseDown)
    self.splitButton.internal = "CONFIRM"

        local totalPoints = 0

        for _, primaryItem in ipairs(firearms) do
            local MetalValue = primaryItem:getMetalValue() or 0
            local points = math.floor((MetalValue / 5) + 0.5)

        self:close()
    else
        ISCollapsableWindow.onMouseDown(self, button)
    end
end

[silent zealot]

But right now the right‐click menu option doesn’t even appear.
Why did you remove the Event Add to add GetReinforcementPoints to teh list of functions called when the context menu is being populated?

Also, rename your functions so it is easier to tell what things do. GetReinforcementPoints should be called something like DisassembleFirearmContextMenu or some such

[solar rover]

I would say double check your image nemes, make sure you dont have any layer issues on the files

[silent zealot]

A quick look through vanilla lua suggest that there is no need, or at least I can't find any case of setVariable() followed by a sync of any sort.

[opal temple]

Oh, I accidentally deleted it. I’ve now added it back, but when I click the option, it throws an error from ISContextMenu.lua.

[silent zealot]

I'm not sure if setVariables is client-only though, that seems to mainly be how they are used and I've not played with them before.

Is using player:modData an option?

[coarse flame]

Does anyone know of any mod that adds something along the lines of high tech equipment? I've always wondered if its possible to have a sort of shoulder-mounted turret or something along the lines of that.

[silent zealot]

I've seen power armor, but mechanically that's just armor with high protection stats.

Also: rayguns, electromagnetic rifles, electric weapons, automated fixed turrets...

[drifting ore]

Are we allowed to make total conversion mods

[bright fog]

Wdym by that ?

Like to completely overhaul the game ?

[drifting ore]

Turn Zomboid into... Not Zomboid

Like Turn the game into something else

Like how Counterstrike is a Total Conversion of Half Life

Or Fallout London is a Total Conversion of Fallout 4

Or Starwind, which is a mod that converts Morrowind into Star Wars

[bright fog]

Yea you can

[drifting ore]

Probably gonna be both extremely hard and possibly hopeless but imma try

[silent zealot]

No-one will stop you, but Zomboid is not a good game for that sort of conversion.

It's very much built around survivor vs: horde of zombies

[drifting ore]

Really? I honestly saw it more as just a Survival Sandbox in general, with realism foundations

[silent zealot]

And lots of game logic is in the java side, which while not impossible to mod... you want to think very carefully before modding any java.

[silent zealot]

You could get rid of the zombies, it's just going to be hard to repalce them with any other sort of enemy.

If you want to go full-on mundane survival, there's definitely an audience for hardcore survival stuff. (not me!)

[drifting ore]

I think it’s worth a shot, If I did a total conversion there’d probably be only one aspect of it that’s wildly apart from the game

But everything else at least from what I’ve observed is entirely possible within the game

[silent zealot]

Do you have a plan for your total conversion?

Or just "chaneg all the things!" lol

[drifting ore]

Yeah, we have a plan on what we need to do, and we want to do a basis of whatever that is before actually building something cohesive

Make bricks before building with them

[silent zealot]

We can probably help you identify likely stumbling blocks so you can investigate those early on/plan around them.

[silent zealot]

Isn't that already in B42? Clay & sand -> bricks

[drifting ore]

That’s a metaphor

[silent zealot]

Also, be aware B42 crafting is still getting worked on, so you might end up duplicating the official changes

[silent zealot]

oh, that's fine then.

[drifting ore]

Changing the way the leveling works, Monsters, NPC’s, Dialogue, etc…

An RPG, basically.

[silent zealot]

When I said we'd help you identify stumbling blocks?

Monsters

NPCS

two big ones right there

[drifting ore]

Monsters can’t be that difficult

I assume it’s mostly behaviors that need work, otherwise it’s animations & health & damage

Modeling as well

[untold turtle]

There isn't any layers for them ill try though!

[silent zealot]

Have you noticed teh lack of new animal mods for B42?

[frank elbow]

You have animals to work with in b42, but since we don't have NPCs monsters in mods have pretty much always just been repurposed zombies (same with NPCs)

[drifting ore]

Then again, I have limited experience modding in the first place

[silent zealot]

AFAIK the animation stuff for animals is broken in a way that stops you adding anything new.

[frank elbow]

I guess you don't have animals to work with then lol

[silent zealot]

And overriding zombies selectively is... a challenge.

Because it's all built for one type of enemy only

[frank elbow]

This is also a stumbling block—the simplest one to get over (with practice and research), but nonetheless

[drifting ore]

True, I’m probably gonna be coming in the help channels often asking for help or advice

[bronze yoke]

that's not correct

[drifting ore]

The idea itself requires a bit of innovation. People have done NPC’s, they’ve done a few things like that, but never to this scale.

[silent zealot]

NPCs... you can have a loot at Bandits/Week One/etc. Those mods are 1) a horrible janky mess and 2) absolutely amazing that so much was done as mods with the current base

[bronze yoke]

we've already added a new animal, there's no significant hurdle, the people saying it's impossible are just making it up for some reason (as with most things people say are impossible i've noticed???)

[drifting ore]

I thought about dming Slayer ab it

[silent zealot]

I thought we were still at the point where the only new animals were just reskinned existing ones?

[drifting ore]

Other than the NPC’s, Monster, Dialogue, and… I guess aspects like quests or whatever that are expected in an RPG, Everything else should be standard. New Tiles, new armor, new items, new guns. Lots of modeling but I’m willing to endure

New Cars

These are all things people have done before iirc

[bronze yoke]

i'm not sure if there are any released animal mods

it's a LOT of asset work

but there isn't any specific technical reason why you can't, you just do it

[silent zealot]

https://steamcommunity.com/sharedfiles/filedetails/?id=3394755161&searchtext=animal This is the only new animal I know of, and it's more or less a pig.

[drifting ore]

I honestly would like to know if what I’m proposing, if any of it is even possible?

[silent zealot]

A lot of it can be done yes, just a matter of time and effort

[drifting ore]

Then I guess I should try and just do it then.

[silent zealot]

Monsters & NPCs are the only two I see as potential big issues.

I suggest break it up in scope and choose what to focus on to start with.

[drifting ore]

I mentioned dialogue, quests, and things like that too

[drifting ore]

I’m someone who believes in doing the hard things first. So probably the monsters and NPC’s.

[silent zealot]

If you have NPCs I don't think dialogue will be a huge problem to implement

[drifting ore]

Think old RPG’s

Dialogue box

Depending on what is said will influence certain behavior/actions of the world or NPC’s

[silent zealot]

Yes, you can just track whatever stats you want with the NPC data

[drifting ore]

We’d have to probably add a new skill

Again, also possible

But something speech related

I guess(?)

[silent zealot]

Not essential, but probably something you want.

[drifting ore]

All of this while keeping most of the core mechanics of Zomboid

Sounds like a party tbh

[silent zealot]

I don't know if you can add a new skill as a "this is a skill" but if you can't, you can definitely just track XP/level in player modData to get the same result.

[drifting ore]

I know some mods have added skills

Like that one brewing mod

My hope is we can get a good enough framework with everything to where we can finally get into the design aspect of it. Basically, design the LEGO pieces, and then build something out of it.

[silent zealot]

Yeah, not something I'd worry about; just something to code when you get to it.

[drifting ore]

But thank you, I appreciate your wisdom

I can’t say for sure this will become a thing, but we’ll see. It simply has to leave the “Pipe-Dream” Phase

Methinks

[silent zealot]

It's a lot of work!

Ideally you'd find a group keen on the idea

[drifting ore]

It’s just me and a buddy

[silent zealot]

but that has it's own challenges dealing with people lol

[drifting ore]

2 people can’t possibly do it by themselves, it could take much longer than a group doing it

But we’re both insane and thuggish enough

We will probably get more people if we need to

There's a PZ Modding Community Discord that has a commissions channel.

https://pzwiki.net/wiki/Mapping

If you're on B42 there is a fan-made tool update; check the sticky posts in the mapping channel.

I have no idea how to fix it, and I don't really understand it.

Do you have any solutions?

Here is the GitHub link:

[github link]

[silent zealot]

The error should tell you which line has the issue

"tried to call nil" normally means you're trying to call a methoid that does not exist, either because of a typo or because the object with the method isn't the right thing (e.g.: it's nil instead of something useful)

[tawdry gale]

Ahh okay, but the method exists in biteMunityClient

function BiteMunityClient.checkForInfections()
    
    if not player then return end
    
    -- Vérification de sécurité pour getGameTime()
    local gameTime = getGameTime()
    if not gameTime then return end
    
    -- Alternative plus sûre pour calculer le temps
    local currentFrame = gameTime:getWorldAgeHours()
    if not currentFrame then
        -- Fallback vers un compteur simple si getWorldAgeHours() échoue
        currentFrame = lastInfectionCheck + 1
    else
        currentFrame = currentFrame * 3600 + (gameTime:getTimeOfDay() or 0)
    end
    
    if currentFrame - lastInfectionCheck < CHECK_INTERVAL then
        return
    end
    [...]
end

[silent zealot]

Which call is triggering the error?

it's something in the checkForInfections function

the full error should give a line number

[tawdry gale]

yeah line 82 but its all function ahah

I'll add a few debug print and get back to you

[normal galleon]

@sweet cipher happy birthday

[tawdry gale]

So... I've added a lot of debugging at each step but actually it doesn't even fit in the function 😅

[tranquil reef]

Do scripts need to use case sensitivity when running on Linux? I have file path references in my clothing files and stuff, some all lowercase which doesn't seem to matter on windows, but will thst break the mod in Linux or does zomboid automatically handle it

[bronze yoke]

sometimes 🙃

be cautious and assume everything is case sensitive

[sturdy salmon]

Good afternoon. Is there a way to edit the UI and see the results? Because sometimes, when you reload from Lua, some features don't work. I don't know if there's a way to edit and see how the interface looks before entering the game.

[agile nacelle]

Isn't there a difference between reloading and restarting lua

Debug mode features restart Lua button

[bright fog]

Send the wiki link

https://pzwiki.net/wiki/Unofficial_Modding_Discord

[bright fog]

Check that

[tawdry gale]

https://steamcommunity.com/sharedfiles/filedetails/?id=3493318320

[silent zealot]

yes - reload from the debug interface re-runs a lua script, but it doesn't cleanup anything it has already done... so that means if the script changed other things or added functions to events it won't be a clean restart. "reload lua" throws everything out and starts over for all lua (and I think all script files too)

[bronze yoke]

i've created another website that hosts documentation of the game's lua, similar to the unofficial javadocs i've been hosting
https://demiurgequantified.github.io/ProjectZomboidLuaDocs/

[silent zealot]

Nice!

Is that B41 or B42?

[bronze yoke]

b42

i don't really do anything with b41 anymore, too much of a pain to go back

[silent zealot]

Agreed, even for mods that woudl be easy to backport it's time to set things up, test, then re-assemble in the workshop folder and upload

And then people will want support on B41.

[bronze yoke]

i'll be honest that my disk space situation is so dire that just having both versions installed is problematic for me 😅

[red tiger]

I'm kind of sad.

Wanted to make that but my older projects got me tied down.

[bronze yoke]

it's pretty basic as of yet, a better solution could definitely come in the future

it only took an hour of development (and 4 hours of fucking about with github workflows 😅)

[red tiger]

Terrifying.

I'm an oldie so I'll do it manually. x)

[bronze yoke]

i'd been planning to as well but when publishing from github pages, it takes an absurd amount of time to push a full website to git (and because of bizarre things doxygen does behind the scenes presumably for performance, every push is a full website push)

the workflow basically just uploads a zip to github instead and that trims off literally ten minutes 😅

might look into doing something similar for the javadocs (they have a similar issue since they store the time of generation inside every file, every file has to be updated every time) but i probably can't generate them from a workflow like i can the lua docs because i actually need a copy of the game to do it

the lua docs generate purely from rosetta data so there's no issues with that there

[frank elbow]

Is it just because it's a whole lot of pages? I've not experienced slow uploads with gh pages but mine have always been like 20~30 files (incl. css and js)

[bronze yoke]

i assume it's mostly file count yeah, i think the javadocs have a few thousand for example

[silent zealot]

If you're not on a laptop, SSD's are constantly getting faster and cheaper.

[crisp dew]

Grrr, is there any docs for B42 for the new craftRecipe, specifically why recipes seem to be empty in the Craft Recipe Debugger with an unfortunately less than useful error 'ISStringListView -> parsing error. out of bounds'?

[tranquil reef]

Do timed actions have to be in a TimedActions folder, or can I put them anywhere

I've always seen them in that folder, but my mod's getting bigger and some fit better in different places

[bronze yoke]

they can be anywhere

other than client/shared/server, folder never matters

(and even those rarely matter)

[tranquil reef]

Thanks

[silent zealot]

https://pzwiki.net/wiki/CraftRecipe

As for the issue, check console.txt for any mention of the recipe name.

But it might be something that gets past the parser but then breaks things that try to display the recipe.

[signal meadow]

Hello good evening, does anyone here know how to create mods for the game?

[bright fog]

Oh wow it shows what it derives from too, that looks neat

Perhaps the arrows should be the other way around ?

What do you think ?

[silent zealot]

Yes.

Multiple modders hang out here.

[supple briar]

Has anything regarding clothes modding changed between b41 and b42?

[silent zealot]

Some new tags, discomfort...

But the process of making a model/texture/etc is all the same. At least I had no isses using B41 intsructions on B42.

[supple briar]

Good to know, gonna try and get my clothing done over the next few days.

I'm starting to want to move onto new projects so I need to force myself to finish the stuff I don't find as fun as modelling and texturing

[dull moss]

#musicmaniacpins b42 docs

[bright fog]

Note this is Lua doc not Java doc

Also I'll make a wiki page about this later today

[silent zealot]

Combine them into Jluva docs

[dull moss]

I know

[pliant cypress]

Hello I am new Making custom mods is there anyway somebody can help me make a gun from models i have for b42

i got custom weapon models but i need help with it to make them work

[signal meadow]

I would really like to meet someone to see if we could meet up so they can make some united mods for my server.

[bright fog]

Someone's working on that, I'm in contact with them

[pliant cypress]

boop

[bright fog]

I'm just not a huge fan of their current lack of transparency but they have stated everything will be open source

[pliant cypress]

I'm actually so excited just got done with the model; but idk how to add the paint to it

[bright fog]

See a Blender tutorial

Also

https://steamcommunity.com/sharedfiles/filedetails/?id=3060255898

[pliant cypress]

the thing is right I already have a model But I'm trying to figure out how to add the textures to it lol

Then I have to see how to import it into pz

[bright fog]

Check the modding Discord to commission modders

[bright fog]

Just watch a Blender tutorial

And check that Steam guide I sent anyway

It has some directives to getting gun models in the game

[bright fog]

https://youtu.be/WjS_zNQNVlw?si=E1Y0Q5BjLMsWFrWE

[pliant cypress]

Thank you I do have a question again doesn't project have like detachable magazines

like guns with no mag

Just so I know if I'm gonna combine the two models together like the magazine and the weapon or keep them separate

[bright fog]

Yea

I think so

But I'm not too knowledgable on guns

[pliant cypress]

Do you think somebody can join vc and help me out a little bit

[bright fog]

I doubt it

[pliant cypress]

wanna give it a try hahaha

[bright fog]

Depends if someone's available but it's unlikely you'll manage to post your message at the same time as someone who's available

I believe the Steam guide is really decent to do most of what you need

Besides maybe some modeling and texturing

[pliant cypress]

I already text the model

It's just getting it zomboid compatible

I'm not going to lie the guns that I'm doing right now I can already tell it's going to be a banger haahhhaha

[silent zealot]

What are you going to use as the texture? Do you have an image file ready?

[pliant cypress]

I already have the texture on the gun

[silent zealot]

That's how I did my gun mods. I made the texture image up in krita, then used UV mapping to map the faces of the model to areas on the texture

[pliant cypress]

The only thing I'm trying to like understand is how to get this ready because I'm reading how to do it but like my brain is not braining

[pliant cypress]

.

[silent zealot]

How did you do the texture in blender

[silent zealot]

Specifically, what is the base colour for the material?

Ok, so grip1_diff is already an image file

[pliant cypress]

Ohh I already have everything on the gun already

Like I'm looking at it right now and it's fully finished it just needs to become compatible and like work for Zomboid

[silent zealot]

Did you use only one image file for the model?

[pliant cypress]

yep

[silent zealot]

What resolution is the image

[pliant cypress]

png

wait im dumb

umm

[silent zealot]

Not file type, resolution. It needs to be in powers of 2 to work in Zomboid

[pliant cypress]

all 3

[silent zealot]

I used 512x512, but you could go list because of how tiny the models are in game

[silent zealot]

What do you mean "all three"

[pliant cypress]

like all 3 are 1024x1024

do you want to join vc

[silent zealot]

No, I'm not up for voice chat

[pliant cypress]

hmm ok

[silent zealot]

Why are there three textures

[pliant cypress]

one for the base one for the grip one for the clip

[silent zealot]

Did you use different image files for different parts of the gun?

[pliant cypress]

yep

[silent zealot]

One model to one texture in Zomboid

Now the clip should be an attachment so it is it's own model

[pliant cypress]

I mean if you want to join vc and we can both mute and I can screen share I can show you what I mean

if thats ok

[silent zealot]

I'm tired and sick and warm in bed, I'm not committing to a screen share troubleshooting session

[pliant cypress]

So basically these are the files of the photos

[silent zealot]

The grip, assuming that is part of the gun and not an optional grip attachment, needs to use the same texture image

[pliant cypress]

No like it's part of the model it's not like an optional attachment

[silent zealot]

Basically for a single model you want one material in blender for every part of it

Also, you can drop the resolution way down... you wont see that level of detail in game

You can probably do something fancy in blender to map everything into one texture image, but that's beyond my blender knowledge. Maye texture baking, but that's meant for lighting effects.

[pliant cypress]

Yeah if I wanted to do that right I would have to make the model all in one but that thing is right I want the magazine to be detachable

[silent zealot]

Or you can open up your favourite image editor, make a 512x512 image that has all the textures you need by combining the images, then redo the UV maps

A detachable mag is a seperate model and can have its own texture file. But it doesn't need to have a seperate texture, and can probably fit into the same image as the rest of the gun used.

The grip cannot have a seperate texture image. You will export the gun body and grip as one .FBX model, and in the model definition for Zomboid you will specify one texture image

[pliant cypress]

hmm i see

[silent zealot]

Like I said, I don't know of an easy way to get there from where you are now; you'll either have to learn some blender tricks or make a single image with the gun body and stock (and may as well add the magazine too) and redo the UV mapping.

[hidden compass]

If I add an attachment slot to a Female/MaleBody model like Authentic Z, is there a problem with the Attachment Editor that causes an error when I select the Player Model in the Editor? Or is it because of the way the attachment is added (to Female/MaleBody)?

I too would like to add a Slot and implement the coordinate settings on the Player Model side, but I am having trouble because the Attachment Editor stops working, although usually play is not a problem.

module Base
{
    model FemaleBody
    {
        mesh = Skinned/FemaleBody,
        static = false,
        animationsMesh = Human,
        
        attachment Canteen_L
        {
            offset = -0.1410 -0.0890 0.0700,
            rotate = -180.0000 -105.0000 154.0000,
            bone = Bip01_Spine1,
        }

The error is below.

[silent zealot]

I don't know if it's due to mods or just broken in B42, but I can't load the player model into the attachment editor without it breaking

I keep forgetting to try with all mods disabled

[hidden compass]

If I add attachment settings for Base.Female/MaleBody, as in the attachment settings in the previous post, the Editor breaks. On the other hand, if I disable those mods, the Editor works fine.

[silent zealot]

That's probably what kills it for me then, I have a "shove a gun or canteen on back of belt" thingy in my personal tweaks mod.

[bright fog]

Hmm I wrote the attachment editor from B42 and it worked back then

[hidden compass]

I also added expansion slots in my own mod, but ended up using vanilla slots (e.g. back, backpack_left) and setting the coordinates on the item side model. However, this is not scalable, so I would like to add my own slots to Player Model if possible.

[silent zealot]

You can probably answer this then; what is the secret to making a weapon model line up properly in attachment editor? I've had no trouble getting weapons to work correctly when help/used/etc, but in attachment editor they always seem to display with the wrong rotation so moving attachment points to match is guesswork.

Except for the latest gun, which was perfect.

So it seems to be something like "you need to have the wepon at this orientation in blender, but you need to have it that away with a specific unapplied rotation transformation."

Or, might be because the latest one was a rifle not a handgun.

[bright fog]

Sorry I meant I wrote the attachment editor wiki page 😭

[silent zealot]

ah that makesa lot more sense lol

[bright fog]

Yea indeed I'm not a dev 😂

[tranquil kindle]

Sadly for some reason adding attachments points on player kinda prevents you from using attachment editor in b42. If you want, you could probably still do it in b41 to save exact location and simply insert it in txt file. Or do everything in txt file in 42, but that's Pain in the rear

I had same issue, but I know I did it the same way as in b41.

[pliant cypress]

ok so my custum gun doesnt show in my hand

like its Invisible

anyone know a fix

[tranquil kindle]

Many reasons for that. You need to provide more

[pliant cypress]

like the gun is Invisible when its spowned in

[bright fog]

I suggest not developping mods whike playing with other mods

Reduces the sources of potential issues

[tranquil kindle]

https://steamcommunity.com/sharedfiles/filedetails/?id=3060255898

[placid yoke]

Does anyone know how to make a sprite with an inventory container lockable using the padlock system?

According to ISPadlockAction.lua, I understand that it should be enough to define the sprite in question as an IsoThumpable, but how do I define it?
I've already tried mimicking the tiledefs of wooden crates in the .tiles file and even creating the item and defining it as thumpable, but it doesn't work.

Does anyone have any idea how I can do it?

[pliant cypress]

The thing is right the model is completely invisible I even try to without mods etc

I went through the subject probably three times triple chacking

I don't know if I'm dumb tbh

i might be to brain dead

[tranquil kindle]

From the top of my head:
-exported empty model (you have file, but there is no actual model in there),

• You have more than 1 material assigned to it

[pliant cypress]

it is thats the thing

[tranquil kindle]

-Its too big/small to be visible
-You put your model/texture in wrong folders,
-a typo in script.txt or model.txt

A gun, which is 1,5 mb fbx file. Something seems fishy by just that to be fair

[pliant cypress]

hmmm

[tranquil kindle]

Just show it in blender aswell as show us your txt files

[pliant cypress]

i sent in dms

[tranquil kindle]

This discord and those channles here are made to Help modders, why should we use DM's for this?

[tranquil kindle]

Someone else might have same issue and it might just help them

[pliant cypress]

thats the model

[tranquil kindle]

Okay, but this doesn't tell me much apart from how its supposed to look like. Just show whole screen, could also use material tabs and still waiting to see your script files where you gun model and gun itself are

[silent zealot]

Press N

Show us the info box that pops up, especially the scale

Actually no need it's on the right

The scale is wrong

It's stupid but... You need to have the scale set to 0.01

So when your model is the correct size in blender (you can compare to existing gun models) you need to make it 100 times bigger, Ctrl-A apply scale transform, then put 0.01 in the scale fields

[tranquil kindle]

Its only for firearms, or any weapon model you want to use with "attachment system"

You could export a machete with 1x1x1 and it would work, but the models that appear on top of you models in case of attachments do require for base model of weapon to be in that scale

Or they .... get messy

[silent zealot]

Rotation matters too; you need it to both look like the model in the example and have the rotation set to same vales as the example

[tranquil kindle]

I know, i made that guide

[silent zealot]

Less important than scale though

[silent zealot]

That was for JoystickJester. Also, thank you! That guide was so helpful.

Other less likely reasons a model might be invisible: texture fails to load (wrong path/ filename, etc... the will be an error in the logs)

[terse delta]

What should I learn in Lua to start modding?

[tranquil kindle]

Still waiting for your item script and model scripts

[silent zealot]

Or for partial missing textures: polygons with more than 4 vertexes (fix with triangulize) or flipped normals (fix by inverting normals where they are wrong)

[silent zealot]

Do you have programming experience in any language/script?

If you know the common stuff like variables, functions, objects, conditionals, arrays/tables, then you can muddle your way through changing Lua by googling "Lua how to do X" a bunch

[terse delta]

I have smol java experience

I understand basic things like this

[silent zealot]

Good enough, just jump in and learn as you go is my suggestion

[terse delta]

There's some kind of zomboid API for lua, isn't it?

[silent zealot]

And don't trust AI. You can ask it general Lua questions and it can be helpful, but if you ask for project Zomboid specific stuff it will lie so much

[terse delta]

Ikr, AI has no idea about small games internal coding

[silent zealot]

Look up "javadocs" in this channel, or on the pz wiki’s modding page

That's the API for interacting with all the java objects in the core game

[terse delta]

Oh, there's some links in pinned

[bronze yoke]

programming in lua is a good fallback for info about the language https://www.lua.org/pil/contents.html

[silent zealot]

I suggest getting VSCode and opening up the games media folder so you can easily search all the vanilla .Lua and .txt files

[terse delta]

A good practice for me to learn Java was dissemination of other mods' source code. This is also a good option here, right?

[silent zealot]

And you can use Zomboid decompiler to easily make a local city of the java code which is great for seeing how things work in the hidden java side

[silent zealot]

Absolutely! Find a mod similar to what you want and see how they did things

Don't straight up copy/paste code, but write your own after seeing how to do it

[terse delta]

I wanted to start from basic, new medicine items

That would require item itself, distribution and function tied to item

[bronze yoke]

believe me nothing related to the health system is basic 😅

[silent zealot]

A lot of that won't even need Lua, other than the distribution.

[terse delta]

What's the markup language for project zomboid? XML?

[silent zealot]

And you can use Easy Distribution mod if you want to make the distribution tables just one line to copy an existing item

[silent zealot]

A bit of everything lol

Some actual XML, like animation sets and some clothing related stuff

Some stuff that looks like Lua but isn't really

Lots of txt files with a custom script design

[terse delta]

It looks like mix of lua and markup language

file that defines properties of item

It's also on wiki for each item

[silent zealot]

Some things are hard coded in java, like the various random "stories" that can appear

[bronze yoke]

the txt format is called zedscript and it's basically just the result of refusing to ever give up on having their own format

[silent zealot]

Good summary lol

[bronze yoke]

in the earliest versions of the game it was supposed to actually be a scripting language (hence the name) but they worked out that lua was just way better for that

so now it's just used for defining things, instead of something reasonable like json, yaml or xml

[terse delta]

thanks god it is not json

It has kilometer-long marking files.

[silent zealot]

I'd take json over zedscript

Plenty of tools to help with with it

[bronze yoke]

zedscript has really inconsistent syntax and being a unique format there's nothing at all to help with it

i've gotta get back to that language server when i get bored of my current projects 😅

[silent zealot]

Xml would be nice, especial with inheritance and xpath patching

[silent zealot]

You can also break the game by putting in something it can't parse, or by putting in something that does parse but then crashes the game because there was zero safety checking

[terse delta]

I wish someone told me algorithm behind sprite style, to me this looks like mess of pixels and i'm unsure how to replicate it

[silent zealot]

Look up pixel art tutorial?

The inventory icons don't have to be high quality because they are so tiny in game

[terse delta]

I mean, i'm used to algorithmes and sequences, and there's no strict way to replicate this

Always had problems with art

[silent zealot]

Better to be distinctive really to help identify things

I hate how many guns are basically a bit of very dark grey and black on a black background

I made the survival rifle icon a lot lighter than the actual gun, so you can actually see the shape

And my other guns were already lighter by design

What do you need to make an icon for?

Sometimes you can save effort by just editing an existing icon

[terse delta]

Some meds.
Activated charcoal, muscle relaxants, anti-anxiety, cough syrup. My plan is to try draw over original textures

[silent zealot]

You can also look for icons online with a free licensee, or use ai to generate an image that you clean up

[terse delta]

AI can't really catch the style of pixel art

[tribal vale]

is the "Player Spawn Area" on sandbox setting broken atm? for spawning zombies inside the safe zone
I can't seem to make it work with custom spawn points

[mellow coral]

hey, does anybody know how to add tags to zomboid mods on steam workshop? Ive just made my first one and the only tag i have is B42

[slim swan]

For my 32px icons, I usually generate a rough sketch using AI first, then redraw everything myself. I even made a simple workflow in ComfyUI for this.

[bright fog]

In the in-game uploader

[mellow coral]

really? When i uploaded it from Project zomboid workshop it only let me take b42 tag

[bright fog]

There's literally dozen others

[slim swan]

Sometimes when I’m drawing icons, it feels like I’m just scribbling randomly ,but the result actually looks not too bad😆

[mellow coral]

okay let me check

[bright fog]

So idk bro but you need to send a screenshot if you don't see others 😅

[mellow coral]

ohh my bad, i see it now. Idk why it didnt let me scroll then. Or maybe it just lagged for a while. Can i edit it from there after upload?

[bright fog]

I think so ?

Hmm no I don't think you can actually

[mellow coral]

well i'll try

[bright fog]

Wait

Did you mean from the workshop ?

Or change the tags

You can modify the tags after the first upload of course

But you need to do it from the in-game uploader

[mellow coral]

okay it worked

[pliant cypress]

Still being a pain

It's not a timed action right? I vaguely remember looking into it and it being hardcoded, but I'm not sure

[true nova]

playerObj:getBodyDamage():setTimeToSneezeOrCough(0) idk if it forces one but this is all i found

[placid yoke]

Still need some help with this!

[thin swan]

Well shit, looks like I'm making a sidecar, for adventures

[proven ibex]

I made a bowl of pea soup feel free to use it 🇳🇱

[crisp dew]

I'm clearly late to the B42 party, (at least in terms of actually working on it). sigh, this damned hardcoded weight system...

Did they announce why this was implemented? I'm working on a system that can hold exactly 12 of something, and 12x15kg exceeds that hardcoded value.

[bright fog]

Someone has made a fix actually

[crisp dew]

Other than the Java replacement fix?

[bright fog]

Yes

Lua sided

Just I need to find it, I think I know where

https://pzwiki.net/wiki/JB_Max_Capacity_Override

[crisp dew]

TYVM! Best I could find was Zuper which was less than elegant.

[bright fog]

Yea the zupper dev kind of went insane since then lol

[crisp dew]

oh?... (not even going to ask)

[bright fog]

Was a joke don't worry

But I remember talking to the guy that forked the original mod to update to B42

And oh boy he was going crazy over this singular issue if I remember right lol

[bronze yoke]

yeah it was a real struggle

i think they quit

[crisp dew]

With this I was contemplating swapping it with number of items instead, but I felt that live-patching items as they're placed into the container to weight '1' would cause more issues.

[bright fog]

Yea I think they did

[bright fog]

Oh yeah that will most definitely cause issues

[crisp dew]

All-in-all for B42 though, I am enjoying the work they did to the crafting / build system; managed to tap into the new build interface to allow the user to immediately place the crafted item in the world.

[bright fog]

I haven't looked at it in depth

But it's a whole UI so it's fully Lua sided, which makes it very easy to customize

Something not many people did before B42 actually

[crisp dew]

module Base {

    xuiSkin default {
        entity ES_TireRackUnpainted {
            LuaWindowClass = ISEntityWindow,
            DisplayName = Unpainted Tire Rack,
            Icon = Item_TireRackUnpainted,
            ToolTip = Tooltip_craft_TireRackUnpainted,
        }
    }

    entity VNGarage.TireRackUnpainted {
...

Threw me off for a bit as they seem to need to run in the base/default namespace, but once I got that namespacing figured out, seems to perform quite nicely.

Sorry I thought you asked if I like to design, I'm too tired lol

[proven ibex]

I feel you lol

Going make bitterballen next lol

[crisp dew]

OOOH, ok, JB's max weight is still overriding the method at the definition level, so it applies to everything in the application; I was hoping to not have to do that, but at least having that functionality in a shared common library will help minimize performance issues.

[bright fog]

Yea it still does some modifications to how Lua interpretes weight and shit I think

[crisp dew]

yup; it overrides the definition, so every container in the game will run the overridden code. That's generally not the best way to do it, but with limited low-level access, is probably the best we can hope for.

[bright fog]

I've seen enough people break their head on the problem to see this as one of the best solution 😅

[crisp dew]

Someone doesn't like combo stacks. 😛

[silent zealot]

I hate them too, but at least it's easy to copy-paste code to handle them (for a context menu option at least)

[crisp dew]

Yeah, right now working on integrating JB's fix, though getting the ever-fun attempted index: addContainer of non-table: null on game boot.

[silent zealot]

I agree, the alternative is you have to override a dozen lua functions from all over the place some of which need to be replaced instead of prefix patched. So buggy, hard to catch every use-case, prone to breaking with updates or not playing nice with other mods that want to do the same for their containers.

Or you hook in to the lua -> java call, decide if you will override or just pass through to the origianl function, and have none of those issues.

[crisp dew]

ah, JB's code needs to go in client and not shared. That makes sense

[supple briar]

Is fileGuidTable still needed in b42?

[crisp dew]

w00t! it can hold 12 tires again! (and the 1-12 item sprite still works even)

(now just to see if I can get that container icon correct...)

[crisp dew]

ContainerButtonIcons = ContainerButtonIcons or {}
ContainerButtonIcons.TireRack = getTexture("media/textures/Item_TireRackUnpainted.png")

Well that was easier than I thought... I'm just an idiot.

[supple briar]

I've given up on the clothes for now, i don't understand them at all and trying to figure it out is making me mad, just gonna finish the cars and come back the clothes later.

[true nova]

clothes arent that hard just need a clothing item script and a clothing xml and a filetable xml and a model and a model script and and and

[supple briar]

No matter what I did they just weren't working, if I keep up with it I'm gonna just abandon the mod. I'm not even trying to make new clothing just retexture some base game ones, but everytime I go in game the clothes throw endless errors and have no tooltips

[silent zealot]

We can help; when you're ready to revisit that

if you're just doing new textures for existing clothing models it's easy to do

fiddly, but easy.

[supple briar]

I'll finish up the other stuff then come back to it, still gotta do schemes and distributions

that way If I get annoyed again I can just release what I have and add clothes later

[silent zealot]

scope creep hits even solo developer mods. 😛

releasing clothing later seems sensible.

[red tiger]

Nothing truer than this on my behalf.

[silent zealot]

Now that the unreal engine can manage hundreds of NPCs doing stuff at once on consumer console hardware I expect your shader mod to make Zomboid look like this: https://youtu.be/FJtF3wzPSrY?t=500

[red tiger]

HTML browser rendering is fun to reimagine in PZ.

I have a functioning box-shadow now

[silent zealot]

In some ways doing that in Zomboid is a lot more impressive than 300 NPCs active in Unreal 5.

[red tiger]

All I want for Christmas is full access to the OpenGL API.

Since the render code is locked in a single-threaded loop with the logic thread of the game, TIS could expose this for the render-thread invocation via their internal API.

Writing a separate layer like SpriteRenderer is another way but ehh

I get why they did that.

I'm honestly surprised that their SpriteRenderer is exposed with shader commands.

[pliant cypress]

[tranquil kindle]

As far as I see I'm one of few that are actually trying to help you. If that's being a "pain in the ass" then I can just simply not. I've seen your model, but I ask for Item Script (your custom item you made with stats and such) as well as model script (assigning mesh and texture) to model ID which is used in item script

[pliant cypress]

Ohh like send you the model in dms

[bright fog]

No he's talking about the scripts that are used to define your item

https://pzwiki.net/wiki/Scripts

[pliant cypress]

Ohhhhh

[tranquil kindle]

Thank you. Yeah I'm at work RN so can't really search for these stuff

[crisp dew]

ok, now that I managed to get my mod working in B42 (at least as a suitable proof of concept), time to go back to B41 and un-break my directory structure so folks back on stable don't get upset.

[abstract summit]

can someone create very underweight mod?

for b42

[bright fog]

Wdym ?

A trait ?

[abstract summit]

yes

its removed in b42

and i used to play with that trait in b41

[bright fog]

Oh really ?

That's interesting

It might be doable but it depends how the game gives the underweight trait I guess

[crisp dew]

am I tripping Sir Doggy, or did you username just change colors?

[bright fog]

yea don't worry about it, it's to be able to pin and use discord markdown for wiki stuff

[mellow coral]

which files in build 42 are responsible in rendering vehicle hud? I have 2 mods that disable car hud and im trying to fix it

[crisp dew]

ahhh, there's a ~/Zomboid/Workshop... I was confused as to why the docs at https://github.com/Project-Zomboid-Community-Modding/pzmc-template wasn't working. (I was deploying my code to ~/Zomboid/mods)

[bright fog]

Check the Mod structure page on the wiki for the whole detail

[crisp dew]

Yeah, I read up on that too, but was confused because I kept trying to implement it inside mods vs Workshop. (My mod for B41 used an automation script to upload to Steam, but it didn't support tags for some reason)

[terse delta]

What kind of IDE you use for lua coding?

[tawdry gale]

Hello, a friend and I would like to test a mod in debug modem, but when I try to connect it tells me I'm not an admin, but it puts me as admin when I connect without debug. Do you have any solutions?

[bright fog]

Vscode

https://pzwiki.net/wiki/Visual_Studio_Code

[crisp dew]

Personally, I use IntelliJ Ultimate, but it's a paid IDE.

[mellow frigate]

VI

[tight elm]

IntelliJ with a plugin for lua

[tranquil reef]

Do I need a mod.info in my mod's root folder if I have one in the b42 one? it's b42 only, not b41 compatible

[mellow frigate]

no

Never heard of Umbrella till now. Does it automatically get the functions from your local zomboid folder, or is it something that gets updated online?

Hello, who knows how to make cars with exclusive designs?

I would like to see if anyone knows how to make unique mods for my server.

[bright fog]

You can send commission requests on the modding Discord, however note that vehicles are not modded by many people

Directly contacting people that created vehicle mods might be better overall

Of course, do it with patience and respect when contacting the modders because they might not appreciate the direct contacting

[bright fog]

ping

[tranquil reef]

Do you actually use it? If so, what do I do about all the "Undefined global" errors?

[bright fog]

You didn't activate it

Umbrella is the norm

Mostly everyone who programs Lua mods use it

[tranquil reef]

"Enable"? or something else

[bright fog]

Yea

[tranquil reef]

Weird, I could've sworn I clicked that and it was already pre-filling different zomboid functions. I guess it just didn't register and was only referencing functions I've already used before or something

Either way thanks

[silent zealot]

ISVehicleDashboard.lua, but it's more likely not rendering because a mod broke something that it uses rather the problem mod editing the dashboard functions directly.

Look for errors in console.txt to give you an idea what is going on, and if you know which mods cause the issue you can also look to see what they are changing

[tranquil reef]

If I make a mod overwriting models in my other mod, should that be above or below the base mod in the load order

[ancient grail]

you wouldnt have to worry about the load order if you require the mod that you want to overwrite

[tranquil reef]

I just did that. I'm trying to overwrite models, it doesn't seem to work automatically

Models with the same folder structure and names

[bronze yoke]

it should be below, but yeah requires should force it to be below anyway

[ancient grail]

i have no idea then

[silent zealot]

I've found the require directive in mod.info doesn't reliably set the mod order. Not an issue for me (since a require directive in the lua files will make lua load properly regardless of order) but would be an issue for "replace an asset by using same path and filename" mods.

[silent zealot]

check the console.txt for any mention of the mod/model.

And doublecheck the path is exactly the same because I have lost hours to weapon vs weapons in the directory structure.

[bronze yoke]

for singleplayer it guarantees the order since singleplayer load order is just the order you enabled the mods in and it's just not possible to enable a dependent mod before the dependency

[silent zealot]

I've enabled a mod with a dependency and had them added to my mod load order as
existing mods
mod I enabled
the dependency needed for the mod I just enabled

easy to fix, but the game should have added them in the proper order

[hidden compass]

Any good ideas for hooking “Right click on each menu (Option)” in the context menu?

I tried hooking ISContextMenu.onMouseUp, but this one only executes if left clicked.

[silent zealot]

You mean if you bring up the context menu then right click on an option?

Does anything in the game work that way - right click to bring up menu/left click on menu is the standard behavior for that sort of UI

[hidden compass]

Yes, I have a mod that makes it easier to get items from containers.
This mod adds a context menu for take items, but I want to have the menu (Option) selection ON/OFF by trigger to be “right click on the menu”.

[silent zealot]

There's a seperate set of events for the right mouse button

OnRightMouseUp

try making a IsCOntextMenu:OnRightMouseUp(x,y) function

I'm not sure if it will get automatically attached to the event or if you will have to manually attach it

ISCOntextMenu:onRightMouseUp(x,y) will be inherited from ISUIElement via ISPanel; it's just an empty function, but you can hook onto it and add your code.

[hidden compass]

Thanks, it will probably work! I should have looked properly until the succession. Thanks again!

It is now possible to toggle ON/OFF by right-clicking on the context menu, which is very convenient in terms of UI. Thank you so much!

[silent zealot]

@sonic needle Arrows in Zombies!

No damage to clothes, the retrieved arrow are always full condition, a few more hit locations could be added, but the core logic works.

[sonic needle]

hell yeah dude 😄

[crisp dew]

Hey SirDoggy, found some notes for CraftRecipe OnCreate; that only works for items. For the new building craft (component CraftRecipe within an entity), it appears that the OnCreate should be within component SpriteConfig. (Refer to media/scripts/entities/furniture/entity_wood_windowglass.txt)

[bright fog]

I'll check that out

Tho note that I haven't dug in the crafting stations

I should tbf

[crisp dew]

The parameters are a bit different too; only one param is sent and it's a Thumpable.

[bright fog]

That's a different OnCreate then probably

The OnCreate which is documented on the wiki should be for the CraftRecipe

Or for items

[crisp dew]

So it's confusing, because buildings also have a CraftRecipe

[bright fog]

The component things are crafting stations tho right ?

[crisp dew]

but it's slightly different...

module Base {

    xuiSkin default {
        entity ES_TireRackUnpainted {
            ...
        }
    }

    entity VNGarage.TireRackUnpainted {
        component UiConfig {
            ...
        }

        component SpriteConfig {
            canBePadlocked = false,
            OnCreate = VNTireRackCommon.OnCreateRecipe,
            ...
        }

        component CraftRecipe {
            timedAction   = BuildMetalStructureMedium,
            time          = 300,
            needToBeLearn = false,
            SkillRequired = MetalWelding:2,
            xpAward       = MetalWelding:20,
            category      = Welding,
            tags          = Welding;Furniture,
            ToolTip       = Tooltip_craft_TireRackUnpainted,
            ...
        }
    }
}

[bright fog]

Yea that's a different OnCreate

[crisp dew]

yeah, just confusing that they're named the same thing

[bright fog]

I guess

[crisp dew]

Currently working on getting my code finished, took me a few to get the debugger to stop, because I didn't realize it went in component SpriteConfig. 😛

[bright fog]

So is that code to define a custom crafting station ?

Or is that also for adding a buildable to the build menu ?
