those are naughty TOS words there young man

we can't javamod

[red tiger]

You can and I've done it in the open for a decade. TIS knows full well I do.

It's what you mod and how you distribute it.

Play nice and they will too.

[odd notch]

they're pretty open about not wanting us to as a general rule, so we tend to shy away as a community from doing as much

however YMMV depending on what you're up to

[tawdry moss]

“We can’t javamod”

Simply another phrase for “I haven’t tried hard enough”

[red tiger]

This is a bad way to look at it. I've seen people go to jail in my 20+ years of modding games. It's not a bad take.

People do stupid stuff. Learn to play by the rules. If you don't know the rules, ask.

[odd notch]

[red tiger]

Just because the gaming community has more-so accepted modding doesn't mean the companies' views on the legality of modifying their IP has changed.

[odd notch]

best for TIS legally to ask we don't run java based bitcoin mining operations on our user's cpus

[drifting ore]

even this sentence is too complicated

[odd notch]

i got the 'making the square' part, let me find a video it's actually kinda neat

[red tiger]

I strongly advocate for what you have rights to do, however I also am more-so an advocate for learning what rights you have.

If you couldn't publish core-mods, then the anti-cheat patch I released in early January of 2022 would've been DMCA'd.

Most core-mods for PZ that come about deal with piracy and cheating so it makes sense to be warry about it.

[tawdry moss]

I’ve tried core modding twice but both times was attempting to find code for vanilla traits

To make different versions of them

[red tiger]

It's sprinkled all over the codebase.

They add in trait checks when calculating or executing events.

[tawdry moss]

I was looking specifically for inconspicuous and cat eyes, but couldn’t find anything in the lua

[red tiger]

Possibly in the lighting thread.

Passed probably to the JNI.

Either that or the shaders.

I hope that frosted glass will eventually find its way into PZ vanilla one day. For now I have to mod it in. =(

Would implement it myself in their code if ever permitted. All they'd need to do is toggle shaders in the UI render context and pass the current FBO as a Texture2D to the shader.

The shader would do the rest.

[odd notch]

result was pretty tho

trouble was, i couldnt think of a way to achieve that bukkit-style of area copy/paste without a lot of nested, ugly code and so it became too cumbersome to continue

found some uses for it, though

[red tiger]

I considered modding a Towny plugin for PZ.

It was for town establishment and protections.

Also building houses, much like the ones already in the game.. not the constructed ones by players.

Would be funny to turn PZ into SimCity.

Have the zombies be citizens and have a full-blown RCI model.

[odd notch]

https://tenor.com/view/rick-and-morty-i-can-answer-that-for-money-gif-10573903

i try to avoid entire gameplay loops unless i'm being paid to make it

i only have so many braincells to rent out

[red tiger]

I mod as deeply as I want really. Depends on the project.

My still-unreleased core-mod for the client has modified code in the deep render code for PZ.

[odd notch]

some of us are helpdesk goblins, mr dev

coding is my funtime heehoo hobby

[red tiger]

Curiosity will eventually kill me.

xD

If ya ain't havin fun, why ya doin it?

[trim mist]

Hmm. More issues happening with this file thing

If anyone has any immediate ideas of what I'm doing wrong, let me know? Otherwise I'm just gonna trudge through this. My first thought is to see if the lines variable is actually getting filled

[pseudo jetty]

yeah good idea

I'm not sure what lines is but if it isn't being filled or is nil or isn't a table

[bronze yoke]

lines() should be a stream, not a table

i'm not sure if you can use streams or not, i usually just do while reader:ready() do local line = reader:readLine() end

[trim mist]

hmm. So no lines variable outside the loop, just do reader:readline. Gotcha

local function addItemTagsFromFile(path, tag)
    if not fileExists(path)
    then
        print("Cannot find file");
        return {};
    end

    local reader = getModFileReader(AnthroTraitsGlobals.ModID, path, false);
    --local lines = reader:lines();
    local line;
    local foundItem;
    local itemTags;

    while reader:ready()
    do
        line = reader:readLine();
        foundItem = getScriptManager().instance:getItem(line);
        if foundItem ~= nil
        then
            itemTags = foundItem:getTags()
            if not itemTags:contains(tag)
            then
                itemTags:add(tag);
                if getDebug()
                then
                    print("tag "..tag.." added to "..line);
                end
            end
        else
            print("Cannot find item "..line.." to add tag "..tag)
        end
        reader:close();
    end
end

[bronze yoke]

you should move reader:close() after the while loop

[trim mist]

oop reader:close is a bit too high

lmao

sorry

Thank you for that. I promise I'm a mostly competent programmer, I just have ADHD

XD

[pseudo jetty]

I'm kind of confused with timed actions, if I create one will the game automatically add it to context menus assuming IsValid is true? If not, how should I trigger them?

[bronze yoke]

you need to add them to the context menus yourself

[gilded hawk]

Does anyone remember which is the event that get's fired once the player spawns?

Events.OnGameStart?

[bronze yoke]

depends exactly what you're going for, OnCreatePlayer might be what you want

[gilded hawk]

Is OnCreatePlayer only fired the first time the player spawns? Or every time the players loads the game after clicking on "this is how you died"?

[bronze yoke]

every time an IsoPlayer object is created

[gilded hawk]

any IsoPlayer? or just yours?

[bronze yoke]

any local one

[gilded hawk]

Good enough

[bronze yoke]

i don't think it fires for multiplayer characters but it does fire for splitscreen characters

[gilded hawk]

Nice!

Thank you

[trim mist]

Is there a way to make testing easier? Every time I test I do the process of
-closing the game
-deleting the mod folder
-copying the mod folder manually to the mods folder
-re opening the game
-deleting the old save
-adding the mods to a new save and waiting
-looking at the error log
-repeat

[bronze yoke]

i just work in the mods directory, and i have my mod disabled on the main menu so that lua reloads whenever i reload the save

[trim mist]

hah! Success!!

Thanks for your help @bronze yoke !

[bronze yoke]

nice!

[timber river]

idk if I'm late or not but in my experience (modding insurgent mod) that event pops for every character spawn, not sure the first one

[ocean sphinx]

is there an easier way to figure out what sound effects are triggered by what action? for example, there are 4 "ui_menu_start" .wav files, and instead of _01 being menu start, it turned out to be when you respawn a new character. I know theres a "ui_menu_start for menu start, "click to start" and respawning a character but idk what the 4th one is for

[bronze yoke]

find the piece of code that triggers them i guess?

[pseudo jetty]

Can I make a wearable item drainable?

[ocean sphinx]

weird.. it seems like it just uses one of the four at random and since its in the .bank file i don't think you can specify it in a script right?

[gilded hawk]

If I do item:getModData() will the moddata be saved in the player savefile once I edit it?

Cause it looks like it's not saving them on my side

[bronze yoke]

it should be saved

[gilded hawk]

Is there any case where it would not be saved, or takes longer to load? Like, i'm truyi

I'm accessing the mod data of an item via the event OnCreatePlayer but it's not working

[nimble spoke]

No, but you can save data in that item that you could use to achieve a similar result

[pseudo jetty]

thank you, I'll look into that

I was also wondering what makes an item able to equip

can I add custom slots and can any types be equip them in?

[nimble spoke]

Clothing items use slots, you can create your own slots

[ancient grail]

#1070852229654917180 message

[lone nest]

thanks, didn't see the sub thread*

[gilded hawk]

Is there any event that gets fired right after OnCreatePlayer ?

Cause it looks like I can't use item:getVisual() at that time

Nevermind, I dumb

[gilded hawk]

What set of characters does the zomboid font support?

[bronze yoke]

the english font should support utf-8

[pseudo jetty]

what does AttachmentsProvided do?

[nimble spoke]

allows your item to provide hotbar slots like a belt does

[hidden jungle]

i'm working on sandbox settings for my mod, how do you set the variable type in the sandbox-settings.txt file?
like boolean, interger, string. google search is flooded with peoples preferences to actual sandbox mode, not the file for modding.
if someone could list out the valid types it would be appreciated.

[trim mist]

local function ATPlayerUpdate(player)
    if player:HasTrait("AT_NaturalTumbler")
    then
        --Fall damage reduced
        player:setFallTime(player:getFallTime() * .5);
    elseif player:HasTrait("AT_ClippedWings")
    then
        --immune to fall damage
        player:setFallTime(0);
    end
end

Events.OnPlayerUpdate.Add(ATPlayerUpdate);

Hoping to pick people's brains here. My Natural Tumbler trait is meant to make things like jumping out of a second story safe, but in testing it prevents all damage, even jumping from 7 floors up.

How should I fix it? Is there an oncollide event for hitting the ground that exists?

As of right now I fear that Natural Tumbler doesn't even allow fall time to get beyond 1

[bronze yoke]

you're halving their fall time every frame, so it's decreasing much much faster than it increases, so it's probably near zero by the time they reach the ground

[hidden jungle]

what you could do is track the current fall value and compare to the previous value every frame, then subtract the difference you want

OldValue = getValue()
function ValueTracking()
 NewValue = getValue()
 Diff = OldValue - NewValue
 NewValue = OldValue + Diff*0.5
 SetValue(NewValue)
 OldValue = NewValue
end

thats how i've been doing it for other stats and its worked fine

[nimble spoke]

There should be an example mod pinned somewhere. If not take a look at a mod that adds these and you will see how it is done

[bronze yoke]

double, string, enum, boolean, integer

[hidden jungle]

is there a way to make it a list of premade options? like how zombie infection has 3 options and not a text box
i'm trying to simplify a large amount of changable settings by having a preset of behaviors instead of 6 seperate interger variables

[bronze yoke]

that would be enum

[hidden jungle]

how do you set it up though? none of the sandbox settings files i've seen use enum so i dont know how to set up the values

[bronze yoke]

i think i have one in one of my mods, one sec

option Literacy.IlliteratePenalty
{
    type = enum,
    numValues = 3,
    default = 2,
    page = Literacy,
    translation = Literacy_IlliteratePenalty,
    valueTranslation = Literacy_IlliteratePenalties,
}
```the value of the enum in lua will be an integer starting from 1

for the value translations, they're Sandbox_valueTranslation_option1 / option2 / etc

[hidden jungle]

thank you, is there a source for this kind of predefined functionality of modding besides projectzomboid.com/modding

[bronze yoke]

not that i've seen

[hidden jungle]

damn, thanks again anyway.

[trim mist]

Thank you!

@red tiger I was wondering since you said you specialize in making mod developing tools. Do you have any experience with Audio Editing software?

Because after releasing my Broadcast voicer mod ( https://steamcommunity.com/sharedfiles/filedetails/?id=2973493897&tscn=1683754850 ) I thought it would be nice to add a custom/modified audio editor that:
. Allows Audio Editing
. Can read a Broadcast Script (what the .xml says, the lines spoken)
. Can assign the times to the script based on how you split the audio

And finally configures everything for you.

[red tiger]

I'm not sure that's possible within the current versions of PZ.

[keen silo]

I was thinking more of an external tool

not inside PZ

(also a programm to make custom radios would be nice too, I guess that there must be one out there)

how do you make zombies spawn with object impaled in them?

is it as simple as adding a weapon to their outfit?

Well. Uh, Definitely works lmao

Did you know that jumping from four stories high kills you without the trait on? I didn't. I guess this test is a success hahaha

[dawn pagoda]

@main lion The chainsaws you added ironically dont seem very good at cutting down trees, ha ha

And also has an absurd attraction range.

[trim mist]

edited this a bit to add some debug prints and to only change falltime if the old falltime is lower. According the the prints earlier, it goes down rapidly once you reach the ground, but not all at once, and I'm assuming a negative value was messing with the decrease

Working on another trait. Anyone know how to get whether or not you're behind a zombie?

instanceof's syntax is instanceof(object, "ClassName")

not instanceof(ClassName, object)

You could probably make an audacity plug-in. Haven't done so myself, I've just used audacity for splitting and labeling generated audio—in my case it was predictable intervals so it just involved a few clicks but presumably labels could help you out here (for use in the plug-in, I mean, but maybe just in general since it could be a tool outside of audacity)

[trim mist]

Thank you! Edited the code above to reflect that

[keen silo]

@frank elbow Is there a tutorial on how to do this? Because I would also like it to show like which line gets asociated with which segment of audio

[frank elbow]

I would assume so. There's an audacity wiki which probably has info on how to create one

[bronze yoke]

you might be able to work out if the player is behind a zombie through however the game determines if short blade weapons should do a backstab

[trim mist]

I'll look into that

[bronze yoke]

there's an IsoGameCharacter isFacingObject, but i'm not really sure what it's expecting for its parameters

isFacingObject(IsoObject object, float dot)

it seems to be a tolerance of some kind? it's probably some maths thing i'm unfamiliar with, vanilla always uses 0.8 so i'd start with that

i think lower is more tolerant, so you might actually want a very low one to determine if the player is behind

[vale vapor]

Hello, java mod can be posted on steam workshop or not? I want to write a simple mod doing the same thing as "Zombie Reanimator" but in java for reduced ressource consumption.

[trim mist]

as far as I know, steam workshop is lua only

[vale vapor]

ok thx.

[bronze yoke]

the game doesn't have any way of loading java mods so while you might put them on the workshop to get it out there, it will require manual installation

@tame mulch Is there any way that Kahlua can expose implemented classes for handling primitive data types? E.G: int[], short[], byte[], or List<Byte>, etc? Thanks.

This would substantially decrease the memory footprint that Kahlua has when handling large amounts of primitive data.

[wet sandal]

Drumsticks are 3u in vanilla?

thats wild

[red tiger]

Wish that PZ used kg

Would allow for more accurate weights.

[bronze yoke]

it's not really supposed to represent weight

[red tiger]

Still, a weight system would be far simpler.

I imagine for Encumbrance the player would always hold the drumsticks like they're ready to drum 24/7.

Hey all, I'm going mad trying to remove a recipe from a mod within my own mod. I've tried all sorts of combos of module, imports, Override, Obsolete, etc... The best thing I can do is just remove all the recipes (by using the same file/module name and having a blank recipe list). Is there a way to selectively remove ONE recipe? I've got my load order set up correctly to load mine last, so it's not that.

Edit: I see above that someone has posted a way to do this with lua, I will give this a go.

Edit: Yup, that works, you the best @weak sierra

Thinking about logo design again..

I never asked anyone about what they thought of my organization's logo design.

WDYT of it?

https://i.imgur.com/ZLnfTK4.png

This was the original back in 2015/2016 when I worked on ModelLoader:

Don't know if anyone here is into logo / media design for their workshop mods etc.

I know @ancient grail does his stuff with his team and that's what made me think about it.

Heh:

Found this one too. xD

[drifting ore]

How can a stick be bigger than a trumpet?

[hidden jungle]

that probably didn't work, your not saving the old fall time between checks. move "beforeFallTime" to a global variable and make sure you set it to the new change at the end of the check

[red tiger]

Okay. Back into the void.

[bronze yoke]

isn't that what the moddata is doing?

[wet sandal]

Thats what I was jokingly complaining about. The sticks weigh 3 and the trumpet weighs 1. So the auto item-sizer did that.

I just overwrote the sizes manually to fix it

[red tiger]

I had a take on how to implement grid inventory systems in PZ.

[trim mist]

It works for sure!

it seems to work just fine in mod data

i'd be loath to put that in a global var since I want this to be compatible with MP anyway

[red tiger]

If I make my own game similar to PZ in the future I'll go with my take.

=)

[bronze yoke]

i'd recommend keeping it in a local variable or a table if you want splitscreen support

moddata doesn't really make sense here

[hidden jungle]

are you sure its working? because with what i read it should be comparing the current fall time to the current fall time, which will always result in 0 as the difference.

[trim mist]

local function ATInitPlayerData(player)

    local modData = player:getModData();

    if modData.ATPlayerData == nil then
        modData.ATPlayerData = {};
        local atData = modData.ATPlayerData;

        atData.trulyInfected = false;
        atData.oldFallTime = 0.0;

    end
end
Events.OnNewGame.Add(ATInitPlayerData);

I thought this was attached to each player. For split screen or other player, is it different?

[red tiger]

It'd be cool too if wearable containers could take damage and depending on the amount they'd randomly drop stuff when walking or running.

[wet sandal]

Evil

[trim mist]

yeah 😅 I printed the fall times, they increase. Fatal fall without the trait is three floors, with the trait it's six.

[red tiger]

I mean.. yeah.. but hey that'd be fun.

[hidden jungle]

OH it does work, i didnt see you had an OldFallTime value being saved in playerdata

nevermind then i'm the stpuid

[trim mist]

if not, maybe doing it via this event might work? https://pzwiki.net/wiki/Modding:Lua_Events/OnCreatePlayer

[red tiger]

I'd also make it so that containers which need to be opened would take time. A grid system could make it so you'd need to remove top items to get to a bottom item.

[bronze yoke]

it is attached to each player, but moddata is mostly for persistence

[red tiger]

Would be insanely more immersive.

[wet sandal]

Both planned, search function and layering big items under small items if the container spawns with more stuff than it normally can fit

[drifting ore]

If I understand correctly, the grid system scales in size with the weight, so something that weighs a lot will fit in the inventory, such as refrigerators, boxes, etc.

[red tiger]

My UI would also be isometric and slide in with alpha transparency say on the right side of the screen.

Like an isometric render of the backpack with each pocket as slightly opaque grids of items.

Maybe you could have backpacks with locks on them too.

TimeAction heaven.

Looking forward to see what you come up with @wet sandal

I may draft my UI visual. I think it's a cool design.

[hidden jungle]

what albion is saying is you can have a table for global data that needs to be saved without being fully SAVED as a character variable.
one gets dumped when the game ends, the other is saved to the player file.
for online multiplayer you don't need to worry about it at all since the scripts dont interact with eachother.
in split screen you can use a table like

local PlayerOldFallTimes = {}
function SetPlayerFallTime(Player)
  PlayerOldFallTimes[getPlayerNum(Player)] = 234
end

[wet sandal]

It sounds cool from how you describe it

[red tiger]

Like the mouse wheel would give so much convenience to scroll through each pocket then middle-mouse click could be to select it. Maybe all of this while holding TAB.

[drifting ore]

And something that weighs a lot, such as a big refrigerator? such as

[bronze yoke]

yeah, moddata is usually used for things you need to be persistent, and sometimes things that don't need to be persistent but are instance specific (though in the case of players this usually isn't needed since a table keyed by player index is probably better)

Does anyone mind giving me a little direct guidance with how PZ functions work with what I want to do. I have 2ish yrs of coding experience (c++ and assembly lang) so I don't need anything crazy. Just some pointers based on your experience. Also, yes, I have been looking at resources. It just helps a lot to be able to ask someone specific questions.

I am new to modding

[pseudo jetty]

same boat

[upper wave]

it's tough working through someone else's code and trying to put together the pieces

what is helping me rn is making a "tier chart" of the function layers

[shy hearth]

what is it you're having trouble with?

[upper wave]

just coordinating what i need to do i guess

this is going to sound dumb, but im trying to make an item that's basically a sourdough starter

i think itd be a great learning process to do more with PZ

[shy hearth]

that sounds rad, it's maybe a bit more involved than what i'd recommend for a first mod but since you have experience already

should be manageable

[heady crystal]

Anybody know if it's possible to check if a TV is playing something through code?

[upper wave]

so the steps here are:
-make an item
-make a recipe
-have it generate more "dough" after a set amount of time. after the set amount of time is reached, require a "refill" with flour and water

im referencing how crops function in the game because, that just makes the most sense once the item is crafted?

is that logical for PZ? @shy hearth

sorry for the ping

[shy hearth]

no worries, feel free to ping

i don't have any experience with running lua from objects but it seems doable

the first two steps are trivially easy and the last one much harder lmao

[upper wave]

YEP

its like, okay, i have the item... now how the fuck do i proceed

i found a mod with code for a potted berry bush. great aspects of this are:
object is craftable
object is movable
object regenerates berries via water input and time

[mellow frigate]

take a mod that implements recipes and see how it is doing it

[bronze yoke]

local deviceData = television:getDeviceData()
if deviceData:isPlayingMedia() or deviceData:isReceivingSignal() then

i wasn't sure if you only wanted it to be if it was specifically playing a tape, if so then you can just drop the isReceivingSignal

[pseudo jetty]

sounds good, usually I find a similar mod like that and can't figure out their lua connects to the scripts lol

[heady crystal]

Can you fetch the specific tape?

Even if it's just a name

[upper wave]

this is a big issue of mine, too

hence trying to piece it all together lmao

reading code only really helps if you know how it works overall

[bronze yoke]

deviceData:getMediaData() returns a MediaData object which has a bunch of getters for stuff like that

[heady crystal]

No way!

This means I can make an awesome mod

Why has nobody done it before

[shy hearth]

we love an awesome mod

[heady crystal]

Thanks a lot @bronze yoke

[upper wave]

is this the place to share updates with my mod

[heady crystal]

I'd talk more about the idea but it'd be a bit sad if I mentioned it here and somebody did it before me 😛

[shy hearth]

totally understand

i hate talking about any project before it's finished lmao

[heady crystal]

If this works, it's gonna change things.

Now do I include it in common sense or make it standalone

🤔

[shy hearth]

people regularly do, but mostly for like 'here's the release of that mod i was asking you guys about'

[upper wave]

ahhh i see

[shy hearth]

Anyone know how to move/teleport players from a serverside lua? setX etc of the player object in question doesn't seem to work

[upper wave]

is it ok to occasionally come for advice

[shy hearth]

100%

encouraged, even

i'm not an authority here but

i'm confident

[upper wave]

i get worried cause some coding communities can be really toxic 😨

[shy hearth]

nah this place is real sweet

[upper wave]

im really glad to hear that

the PZ community seems great overall

[shy hearth]

mostly i come back to search in:mod_development with whatever it is i'm looking to do

and someone has asked it already and usually been given a solution

[heady crystal]

Overall it's amazing

[bronze yoke]

i wouldn't be surprised if you can't

[heady crystal]

As an Android developer I am used to people complaining about the smallest and silliest things and being super toxic overall. Here people are absolutely fantastic. Lots of people willing to help with the craziest ideas and you get a lot of support from the community with any mod as simple as it may be

[shy hearth]

yet another reason to want GameServer exposed

i'm sure there's a hacky workaround

[bronze yoke]

on the client, you have to use this monster afaik```lua
player:setX(x)
player:setY(y)
player:setZ(z)

player:setLx(x)
player:setLy(y)
player:setLz(z)

[shy hearth]

does that still trigger anti-cheat 12 dya know?

[bronze yoke]

try it from the serverside but most likely you'll need to send a server command with the desired coordinates

no idea

[upper wave]

more reason to love the PZ community 😄

[shy hearth]

aye it's what i'm doing from the server rn, no errors but no results

i'll see if it bothers the anti-cheat then

thanks albion

[bronze yoke]

when i tested my mod locally i didn't run into any anti-cheat issues

[shy hearth]

okay excellent, i'll report back for future reference

[upper wave]

i first should make the item and have it placeable and then move on to the complicated stuff

[wet sandal]

I'm finally ready to sync my moddata for multiplayer.
It can only be stored in 2 types, either an InventoryContainerItem or an IsoObject.

Anyone know the api calls or a mod that syncs data properly I can quickly check out?

[bronze yoke]

sync moddata? you just call object:transmitModData()

[shy hearth]

first place i would start is figuring out how to trigger lua functions from objects

[wet sandal]

Thats it?

Excellent

[shy hearth]

a hacky way to go about it is to have a recipe to 'reload' flour and water into the starter

when the recipe is created change a boolean to start a timer

[bronze yoke]

note that items and players don't need to transmit mod data at all, it's synced by default

[shy hearth]

after the timer replace the crafted recipe with two units of the initial starter, or something

idk how bread works

outside my wheelhouse

[upper wave]

yeahh i considered this as an alternative

[bronze yoke]

and you should *always* transmit mod data, even if you don't need to, because moddata transmission overwrites the existing moddata so if you don't transmit yours another mod transmitting from another client could erase the local data

[upper wave]

but its not really what i ultimately want

it might be a good start just for learning

[shy hearth]

honestly i'd go with the hacky solution for now since crafting is changing next update

but yea if it's a learning exercise

better to do it right

[upper wave]

the sourdough starter is prob the most complicated part of my overall plan

my main goal is a bakery mod pretty much

idk how many people would be interested in it, but my friend and i would have fun with it lmao

[shy hearth]

have you checked to see if anyone has made anything similar? i think there's a bakery-like mod out there

it might not still be supported

[upper wave]

it could be a good point of reference

[shy hearth]

i would 100% play with the bakery mod so if you can make it then do

please add potato flour

[upper wave]

i have an artist background before becoming a programmer, so ill be able to edit models n shit

[shy hearth]

i want to forage for my bread lmao

[upper wave]

ooo i didnt even know about potato flour

thank you for informing me

ill definitely add that

[shy hearth]

you can make a form of flour from basically anything starchy i believe

okay maybe i do know a lil about bread

[upper wave]

you know more than me 😭 and im supposed to be making the mod

im researching recipes n stuff

[shy hearth]

nah i learned it all from cataclysmDDA

[upper wave]

im hoping itll be a nice, lightweight, QOL addition to the game

[shy hearth]

can take no credit

[upper wave]

who's that??

igoogle rq

ooo another game

ZOmbie game even

[shy hearth]

yea zomboid is sort of a spiritual sequel to CDDA, although that's not official i believe

anyway best of luck with your cookin jesse

[red tiger]

Remember kids: Always document your code.

Or the Lua goblins will eat you.

[shy hearth]

lua goblins aren't real they can't hurt you

[red tiger]

Correction: They hurt with you.

[shy hearth]

you only need to comment the name of your function above the function

[red tiger]

They are emotional creatures.

[shy hearth]

that's all

lmao

i shouldn't even joke about it, since modder comments are basically 95% of the entire documentation for zomboid

[red tiger]

https://tenor.com/view/we-got-him-ladies-and-gentlemen-em-gif-15781907

[upper wave]

bless

[red tiger]

"My code is self-documenting."
(Calls 911)

[shy hearth]

shouldn't have messed with the lua goblins, now i'm in rosewood pen

[upper wave]

only professional programmers know this 1 trick

[red tiger]

I literally wrote a tool and a JSON library for applying documentation to PipeWrench's generated typings.

xD

Funny how you say that.

[shy hearth]

i saw you talking about UML somewhere

[upper wave]

man, i really need to start figuring out what lua is exactly

[shy hearth]

sighed to myself and went back to comment my code

[shy hearth]

it's tables

that's all it is

[red tiger]

#1 PZ Lua isn't real Lua.

[upper wave]

of data?

[shy hearth]

tables all the way down

[red tiger]

Keep that in mind.

[shy hearth]

the strings? tables. integers? tables. the tables?

you better believe they're tables

i'm not even joking

[upper wave]

sry if i sound dumb, im not experienced at all with game coding

is it where the game saves data?

like objects

[shy hearth]

nah it's like a data structure

[upper wave]

holee shit

[shy hearth]

it's crazy to me how advanced the modding community here is

and there are like

[red tiger]

Letting you know that you're preaching to the guy who solely focuses on literally that.

[shy hearth]

no tutorials out there

[upper wave]

i was thinking of a system like this to really lay out the connections between functions

[upper wave]

and the tutorials that do exist arent for beginner modders

[shy hearth]

yea the learning curve really starts at doing an autopsy of someone else's mod

which you need prior experience and much patience to do

[red tiger]

Also my vscode extension for ZedScript

Which I haven't touched in a few weeks.

[shy hearth]

i've learned to fear anyone who writes extensions for ides

[upper wave]

i only feel capable bc ive felt like "idek know where to start or how to get to B from A" many times in the past with coding

and eventually i work my way to B

[shy hearth]

yea it's what makes it fun tbh

[upper wave]

one step at a time rule

[red tiger]

I mean.. We could make tutorials.

[shy hearth]

i would go off and learn the basic concept of what lua is if i were you

[upper wave]

i have a problem where i think too far ahead and get thrown off on the early steps

[shy hearth]

it'll save you unlearning a lot of stuff

[red tiger]

I need a good microphone to do it.

[shy hearth]

that's exactly where i am

[red tiger]

I'd be down with it.

[shy hearth]

needing a mic

[red tiger]

Just donate to me 4head

lol

[shy hearth]

considering just buying the tokens to get an AI to voice it

[upper wave]

yeah that seems critical rn honestly. just with understanding the communication

[red tiger]

I am no longer asking.

[shy hearth]

the bernie sanders meme

but for a blue yeti

[red tiger]

USB microphones are terrible.

They pick up all the high frequency noise in the background.

[shy hearth]

great, gonna have to learn audio mixing now too

[upper wave]

i am happy about where im at rn with coding. the learning curve for c++ was INTENSE

[red tiger]

I used to be a proud owner of a Shure SM7B.

[upper wave]

it's my first prog lang

[shy hearth]

c++ is a rough starter tbf

[upper wave]

i did start with C first actually

but quickly moved to c++

[red tiger]

I started with ASM technically which failed and then JavaScript.. Then Java.

[shy hearth]

C is almost better because it lets you blow everything up

sink or swim

[upper wave]

i s2g the people that say it's easy, have never done anything actually complicated with it

[shy hearth]

pretty cursed path tbh

but it worked out for ya

[upper wave]

misspells 1 int:
IDE: 03188x800 dhajabxbaksieyq8worjhaka 000234

[red tiger]

I'm a cursed individual.

Have you seen my work?

[shy hearth]

i just went to university like a loser

[upper wave]

but 20 more lines of this

[red tiger]

I modded minecraft back in 2010 without any mod tools.

I fixed broken decompiled code.

I do it on PZ.

[shy hearth]

at least you can do the 'can you give me a few pointers' joke

[upper wave]

im in college:D

[red tiger]

I'm a mod goblin.

[upper wave]

comp sci student

[upper wave]

LMAO

you know what's helped me tremendously with pointers

learning assembly

[red tiger]

Pointer to left-stage exit.

[shy hearth]

ahaha

you guys are nuts

i'm doing back to my mod

[upper wave]

do you know MIPS?

[upper wave]

i swear just the basics are great

helps my understanding of programming a lot

im going to be building my own IDE next semester (same prof, he has told us this)

[red tiger]

I don't know MIPS.

Been poking at x86 lately.

Was thinking about building a PZ mod where you can access computers and write code in ASM.

[upper wave]

🫡

[red tiger]

Or you could make it

And show your prof

[upper wave]

now that is beyond me rn my friend

[red tiger]

Do the craziest project you can think of.

Insanity makes the best programmers.

[spice saddle]

Just in case PZ wasn’t masochistic enough you want players to write assembly? Haha

You could create books to help them learn programming skills

[red tiger]

I mean.. it's 1993.

[red tiger]

Fucking fantastic idea.

[spice saddle]

O’Reilly’s GOTO Instruction Manual “some bird on front page”

Dummy’s Guide to How to Access MainFrame 101

[red tiger]

You're late-game in 1994.. Why not write AOL?

[lone nest]

Not sure who can live like its 1993, when Radio Shack was king and internet was capped at like 14 kb/s.

[red tiger]

My life be like

[spice saddle]

You know I did think it’d be cool if i could make mods that’d allow players to play some silly games

Idk like Number Muncher

Oregon Trail

But I never thought about learning assembly lol

[upper wave]

absolutely omg. you have to be so dedicated for this shit 😭

[red tiger]

If TIS can spend a few minutes and expose implemented array-like classes for packaging primitive numeric values I'd make an ASM emulator.

[red tiger]

xD

[spice saddle]

[lone nest]

https://en.wikipedia.org/wiki/Third_generation_of_video_game_consoles

[red tiger]

My proof of insanity was writing two transpilers so you can write PZ mods in TypeScript.

=)

[lone nest]

I still need to try that out, but I'm not writing mods from scratch yet.

[spice saddle]

TypeScript -> Lua?

[red tiger]

https://i.imgur.com/AP94LfV.png
https://i.imgur.com/cnt4Ik5.png

[spice saddle]

:O

nifty

[shy hearth]

just occurred to me, you could probably do something with the ReplaceOnRotten item parameter and modify the rot time

[red tiger]

Make a RPG sword that evolves over time.

[shy hearth]

oh dear god

[upper wave]

this ASM class has been my easiest comp sci class by far tbh. the key for me is to just not think too hard. just let my fingers type 🫡

[red tiger]

This is literally everyone in Fundamentals.

[upper wave]

best part about ASM is that nothing is hidden

[spice saddle]

The more zombie blood it drinks, more powerful the sword gets?

[shy hearth]

surely someone has made that already

[bronze yoke]

somebody's gotta work out a way to grab the parameter names from the reference site

[shy hearth]

to link automatically?

[bronze yoke]

yeah, there's only so much use you can get out of arg0, arg1, arg2

[spice saddle]

Did you just volunteer? Lol

[upper wave]

yeah i bet. i dont even want to begin to think making something super conplicated with asm

oops meant to reply

[red tiger]

I can write a scraper for the docs.

[shy hearth]

i get so angry looking at the decompiled code

by the time i reach n18

[bronze yoke]

maybe... i haven't really any experience with that sort of thing

[red tiger]

I actually scraped the whole javadocs for offline use. Want it?

[shy hearth]

in a sea of unnamed variables

[red tiger]

crawled it using grep

[bronze yoke]

i think i already got it off of you actually

[spice saddle]

👀

[shy hearth]

give give

[spice saddle]

I’d be .. interested…

[shy hearth]

i think i bookmarked it actually

but just in case

[spice saddle]

Oh it’s online somewhere?

[shy hearth]

@upper wave save this https://pzwiki.net/wiki/Scripts_guide/Item_Script_Parameters

[upper wave]

NICE

[shy hearth]

aiteron finished it fairly recently

[upper wave]

thank youuu

[shy hearth]

actually what i have was the list of lua events decompiled, not what jab is talkin about

[red tiger]

I can't find it.

[shy hearth]

so yes jab give us the goods

[red tiger]

Looking for it.

[pseudo jetty]

wow

[spice saddle]

I haven’t really started looking into modding yet but that sounds helpful

[shy hearth]

give aiteron props, they worked real hard on it

the lua events decompiled is here

https://paste.sr.ht/~ckyb/99d2d134360d355f33ceecf255b971f6b1d03624#Project Zomboid 41.78 LuaEventManager Java + Lua Events - now with args!-L10

[spice saddle]

Thank you Sir

[shy hearth]

my pleasure, just passing on someone else's work

[upper wave]

the type of shit i aspire to be capable of

amazing

[shy hearth]

some real auteurs in here

[spice saddle]

Is this listed in one of the mod resources/tools thread?

I hope it is

[shy hearth]

i haven't checked actually

i just bookmark as i go

you'll find a lot of hidden gems using the discord search filters in this chat

[spice saddle]

I lose track of links all t he time.. ugh need to do something’s bout it

[shy hearth]

sitting down with a glass of cool lemonade

[red tiger]

@shy hearth @spice saddle

[shy hearth]

reading cover to cover

[red tiger]

It's more of a local clone of the website

projectzomboid.com/modding

[shy hearth]

yea handy to have

[red tiger]

I can take this website and scrape it with code to extract param names.

[shy hearth]

does anyone have a zip of all the zomboid classes decompiled?

that's the true holy grail for me rn

[red tiger]

Not wise to ask. (Illegal)

Also

[shy hearth]

i see i see

question retracted

[red tiger]

You can use IntelliJ IDEA and double click or open a .class file.

[upper wave]

sry i just saw this. this is a great idea

[shy hearth]

does intelliJ still have a community version?

[red tiger]

Of course.

[shy hearth]

or dya have to pay

i remember struggling to find it before

[red tiger]

I use IDEA.

[shy hearth]

VSC for life

[red tiger]

I use VSC for all scripting langs.

[upper wave]

i couldn't get vsc to work

i should try again

[shy hearth]

so lightweight

i love it

[red tiger]

How? It's so simple.

It's an electron app iirc

[upper wave]

i last tried a year ago wheni was even more of a baby programmer

i was getting a weird error

i tried googling and could find 0 solutions

[shy hearth]

it's so simple that if you don't know what you want from it it won't give you anything at all

[red tiger]

I love the terminal but I wish I could undock it.

[upper wave]

it was something to do with a java function

i forgot what specifically

i tried 3 solutions via my professor and kept getting the same issue

[red tiger]

Well if you get accustomed to vscode there's an extension I work on for you to use for script files.

[spice saddle]

TY!

[upper wave]

i'll work on it again after finals week

that's great to know

it'll prob be fine this time

[red tiger]

Got to get a working linter one of these days..

Then the fun can begin on formatting.

[fading horizon]

Which bip bone do hats attach do? Head or head nub?

Currently my model looks like this in game which i'm pretty sure is due to the bone thing

what it's supposed to look like

normals are all good as well, no issue there

[novel swallow]

Is there anyway to see what mod added a recipe object from getScriptManager():getAllRecipes()? I poked around in the debugger and couldn't see any fields/functions that did this.

[fading horizon]

increasing size does not help either

[bronze yoke]

i don't think it tracks this, this was only added to items very recently

well... very recently in relative terms

[novel swallow]

darn, was worried of that. Hmm.

[bronze yoke]

if the mod is written properly the module name might help

but if they're dumping everything in base that's no good

[novel swallow]

Huh, it is in its own module. Will that be in the recipe somewhere?

[bronze yoke]

yeah, recipe:getModule():getName()

[novel swallow]

Hmm, that doesn't seem to work for me.

Oh, I did . instead of :, still getting used to lua

Absolutely perfect. You just saved me a ton of horrible code and effort.

[gilded hawk]

Is there a limit to how many files I can put inside fileGuidTable.xml ?

[late hound]

no

[gilded hawk]

Odd, my clothings are not loading 🤔
And the tooltip is empty and it's firing errors when visible

[late hound]

head. The reason I think that there are nub bones is that they signify the different ends of the skeleton. I also think its an export preference for 3DS Max, which is what TIS used to make the models. Its similar to how leaf bones work in Blender.

[fading horizon]

I see, thank you

I think it's actually an issue with vertex weights, because changing that in weight paint modifies how it looks

idk, i'll have to look into how other mods did it more

on an unrelated note, look how cool my character looks now lol with all my mods

https://cdn.discordapp.com/attachments/1038181044786053130/1106358082029752380/image.png

[gilded hawk]

Is there any specific name convention to follow for the Script item name?

[late hound]

not really, just be consistent

[gilded hawk]

Damn

[gilded hawk]

Does anything come to mind that can cause this issue?

[late hound]

looks like a GUID mismatch or clothing item xml name mismatch

[gilded hawk]

The script item name, can be the same name as the ClothingItem ?

[late hound]

yes

[gilded hawk]

😐

On my end it looks like it's fine

[trim mist]

Made a short video detailing an issue I'm having that i need some insight on! Here's a side of relevant code!

local function ATOnCharacterCollide(collider, collidee)
    local knockdownEndCost = SandboxVars.AnthroTraits.BullRushKnockdownEndCost
    local colliderBehindCollidee = collidee:isFacingObject(collider, 0.5);
    if instanceof(collider, "IsoPlayer" )
    then
        collider:setIgnoreStaggerBack(false);
        if getDebug()
        then
            print("colliderBehindCollidee: "..tostring(colliderBehindCollidee));
            print("Is Sprinting: "..tostring(collider:isSprinting()));
            print("Tripping: "..tostring(collider:getStats():isTripping()))
        end

        then
            if instanceof(collidee, "IsoZombie")
            then
                collidee:setStaggerBack(true);

                collider:setBumpStaggered(false);
                collider:setBumpFall(false);
                --collider:setIgnoreStaggerBack(true);
            elseif instanceof(collidee, "IsoPlayer") and ((collider:getCoopPVP() == true and collidee:getCoopPVP() == true) or collidee.isZombie())
            then
                collidee:setBumpStaggered(true)
                collidee:setKnockedDown(true);
                collider:getStats():setEndurance(collider:getStats():getEndurance() - knockdownEndCost)

            end
        end
    end
end

Events.OnCharacterCollide.Add(ATOnCharacterCollide)

Sorry to interrupt! I'll brb, eating some dinner and I'll take a look at the chat after

[gilded hawk]

This makes no sense, the GUIDs are correct, the names are correct wtf is wrong

Like, does anyone see anything wrong here?

Even the names are matching wtffffffffffff

[ancient grail]

I didnt know theres a setIgnoreStaggerBack()

Thats pretty useful

Does it work

[gilded hawk]

IIRC more traits has a bull rush trait, maybe you can take a look at it

[ancient grail]

I think youre missing a name and a path on the xml file thats inside the clothing folder

[gilded hawk]

What do you mean?

[ancient grail]

The image in the middle

Is that how its written? Im on mobile
But iirc its missing some stuff

[gilded hawk]

if you are referring m_MaleModel and m_FemaleModel I did not fill them in intentionally, it's an empty model, like the Belt

[ancient grail]

Right

Myy bad

[pseudo jetty]

could anyone explain to me how to associate a lua table with a certain item? I'm trying to store the number of times and object has been used. Thank you

[gilded hawk]

Maybe one of the known clothing modders can take a look at this, because this problem has put a massive roadblock in my testing

[ancient grail]

Try modelling?

[gilded hawk]

yeah

[ancient grail]

Im pretty sure he ment you @

[gilded hawk]

...

I think I figured the issue

[ancient grail]

What was it

I was also looking at that
Thinking i think theres something missing but not quite sure
I knew it should be a path to xml

But i thought maybe it was the model

[gilded hawk]

It's the missing </files>

Yeah

[ancient grail]

Was looking st the 2nd img
All this time it was the guid xml lol

Ajhh i see

Lol so it wasnt shown after all

[gilded hawk]

Yeah this wasted me so much time 😦

[fading horizon]

How would I override a vanilla items script parameter? Like if I wanted to add an evolved recipe to a food item that doesn't have one

I tried just having it as the same name and parameters + my custom parameter ; however, that did not work

[novel swallow]

Can I add recipes via lua?

[fading horizon]

can you elaborate?

like what kind of recipe are you trying to do

[novel swallow]

I'm trying to dynamically create a fairly simple recipe, just a straight one item for another.

I could write it as definitions but I'm doing weird stuff with detecting mods so can't rely on the .txt files, as I'd need loads of sub mods and one would have to manually enable them

oh sick!

are u going to have all the colors

[fading horizon]

of course

fixed it

[pseudo jetty]

quick question is there a way to get a unique id for every inventory item?

[sand citrus]

I want to display a string of text to the console to help with my lua debugging. How do reference the console? I am assuming it is basically "something.print(STRING)" at the most basic just going by some lua references.

[pseudo jetty]

print()

[trim mist]

it does SOMETHING, but I can't really tell what

[trim mist]

I have! but uh, they do it completely differently

[gilded hawk]

interesting

[trim mist]

So I didn't know if it was like. A legacy thing or...

The programmer did some hacky stuff like using ghost mode here and there

and they do the whole thing in the OnPlayerMove event

[gilded hawk]

Yeah I assumed ghost mode would be involved

[sand citrus]

Thank you very much.

[wicked zealot]

hi guys i'm trying to do a mod that adds passenger seats for the truck bed and that lets you shoot, i discovered how to add the passenger seats and make the model appear in the back but i dont know how to add the turning animation to the model, does anyone know?

How can I provide myself entertainment without a fog machine to make my own basement rave?

[ancient grail]

Wht r u trying to do

[ancient grail]

You should look for the server command to cast the smoke

[trim mist]

Long story short, knock over zombies when sprinting, stop the bumping action on the player, and figure out why the player gets trapped in an animation when hitting 3+ zombies clustered together

[ancient grail]

Maybe cuz of dragged down

It triggers players to get eaten
While you are forcing it to not react maybe

[trim mist]

Took off god mode. The animation freezing thing that happened above happened when I hit 2 zombies at the same time

[bronze yoke]

InventoryItem:getID()

[pseudo jetty]

thank you

[bronze yoke]

ids are the same across server/client and i think persistent too

[pseudo jetty]

and I also have kind of a general question about mod data
If you do item:getModdata() is that exlusive to the item? Can I use that to store data about the specific item?

[bronze yoke]

yeah

[pseudo jetty]

great

thank you

I thought it was global or something and I was going to put the id as an index

Update to my shops and traders mod, now featuring player ran shops. 👍 Shout-out to BowlOfOodaLoops for sponsoring the endeavor.

I'd appreciate any feedback that can be given

I want this tank to be used from two squares and now it works by having two pumps. If I leave only one pump so it's the same level of fuel which actions would I need to patch? I know worldobject context and radial for vehicle, any other menus?

[fast galleon]

hm, maybe I can do patch for the function that finds the fuel pumps and sync the levels there.

[tawny pendant]

Question: does anyone know if it’s possible to mod the game so that the player can carry more than 50 pounds of stuff at a time in the main inventory (the one displayed by that cardboard box)

[novel swallow]

This might be a really easy question as it's basic .lua which I'm still new to but: Can I define functions in one file and call them in another? So I can have like helper functions I reuse. Not sure how lua works/executes, or if I have to write a line to import it.

[fast galleon]

You can use any global function directly.

You can also make modules by making a file return a table, and using

local module = require "file"

you should search for how require works in pz if you use this

[novel swallow]

So does that file basically return a {} with the functions you want as properties?

[novel swallow]

Cool, so basically how js modules work under the hood 😅

Thanks all, as always. I popped my head in last night and have already posted like three questions but everyone's been helpful and massively improved my understanding of lua/pz modding.

I'd been Googling/reading the forums all week with no progress - turns out the discord is where it's at.

[thin hornet]

shared/fileA.lua

local x = 0 -- Private variable as its never exported
function funcA()
  x = x + 1
end

return {
  funcA = funcA
}

client/fileB.lua

local utils = require('fileA')

utils.funcA()

a lua file can return something and be imported later.

[thin hornet]

also if you come from a js background you may wanna look at pipewrench and pzpw
https://github.com/Konijima/pzpw/wiki/Tutorial:-Creating-Project-Zomboid-mods-using-PZPW

[novel swallow]

Oh nice. I've literally been using TypeScript to process data and write recipe blocks for me and just copy pasting them 😅

Thank you very much

[thin hornet]

if you want to see example of pzpw mods, here my latest using the latest version of pzpw
https://github.com/PZPW-Mods/Death-Log

[novel swallow]

Does that have types for the pz built ins? Because that would be amazing

[thin hornet]

yes, pzpw uses pipewrench, so basically you have intelisense for all of pz java side and lua side

[novel swallow]

😱

You have probably just increased my efficiency by several orders of magnitude.

I will check that out for sure - thank you!

[thin hornet]

if you have question don't hesitate to ask! 😄
also check out some example (maybe outdated) in the wiki
https://github.com/asledgehammer/PipeWrench/wiki

[novel swallow]

I'm sure you'll hear from me, haha. I have an extensive programming background - but never lua (apart from some light stuff in gmod) or PZ. Been really struggling to even discover what types/functions/etc I have available to me. So using TS (my current language of choice) with intellisense will be huge.

Also, I was ranting to my friends yesterday how backwards lua is - so many things about it make me 😬

[red tiger]

Don't worry. You're not the only one that does that with Lua.

PipeWrench started as a joke and critique of Lua.

[novel swallow]

Well I'm glad it exists, my thanks to all involved who made it real haha

Am I able to go TS mad in this? Like is there anything it doesn't support?

Can I just be creating my own types, lambda expressions, etc, all over the shop?

[red tiger]

For some missing or any types for the Lua codebase of PZ you can write Lua interfaces and mix TS code with Lua

[red tiger]

There's some caveats. Look up TypescriptToLua.

[novel swallow]

Hmm is there any reason ArrayList<E> get method returns any and not E?

[red tiger]

I was the only developer for PipeWrench. I had a lot of help getting it to auto run for updates on PZ versions.

[red tiger]

I only exposed what PZ exposes.

[novel swallow]

Hmm, okay, fair.

[red tiger]

I wrote the code that inspects and traces what is exposed and the generics as well.

[novel swallow]

nice

That's a good idea

Basically just pull out everything and make ts typedefs for it, so we can have intellisense

[red tiger]

Not only that but type safety

[novel swallow]

Yeah, that's what I was hoping but the first thing I went to use returned any despite it being generic haha

[red tiger]

PipeWrench is powerful.

[novel swallow]

var recipe = recipes.get(i) as zombie.scripting.objects.Recipe; is what I ended up doing for now, as I know that's the underlying type

[red tiger]

Or use import deconstruct

I should get back to my rewrite of the Lua to Typescript transpiler.

I shelved that to work on a vscode extension for ZedScript for a few months.

I shelved that right when I had a breakthrough on emulating PZ pseudo classes in their Lua codebase.

[novel swallow]

I am getting a little confused with the type hinting

I see types in the typedef file, but just any in my actual scripts?

[red tiger]

Probably something that I had to do to get it to play nice before I finished generics support

I was thinking about rewriting the transpiler in Typescript and to have it use source files instead of reflection in runtime.

Reflection is a terrible way to extract generics since that's all but erased at runtime.

[novel swallow]

Yeah, in Java, they'll all exist and you'll be able to probe to no end the generic types of any params and returns.

TS on the other hand, types aren't real once it's transpiled to JS, so I assume the same is true for transpiling to lua.

However, these are just typedefs in the TS world so should be fine/doable.

It'll depend on the java code and what's visible (which I haven't seen so can't really comment). This stuff is still massively helpful, I just have to be a bit creative/cast things.

[red tiger]

Yeah. I code JS at work entirely with typedefs.. something I chose to do.

I go hard on it.

My work refuses to adapt to TypeScript.

[novel swallow]

oh no :x I work in an entire TS stack for both backend and frontend.

[red tiger]

This is a really oldschool website.

Oldschool boss.

He doesn't do JS though.

[novel swallow]

Yeah, I used to work on a 15 year old PHP application - old stuff gets stuck haha

[red tiger]

I've worked in Java for over 15 years. JS for around 10 on and off.

TS for about 5

Try ASP.NET framework 4.8.

I can't use modern C# syntax sugar. 99% of the code is in VB.

I'm changing that.

lol

[novel swallow]

D: C# is actually one of my personal faves
Couple jobs ago I was the sole maintainer of a c# solution that we had to remote desktop in to some laptop that had a vs2008 (or something) license as it was the only way to build it (and they only wanted to buy one license).

I ported it to .net core 2.0 when that was new, built it a new pipeline and auto deploy jobs.

[red tiger]

Nope.

I code in VSCode.

[novel swallow]

I use Rider for C#, but VSCode for everything else.

[red tiger]

Visual Studio is too freaking big and also it's cumbersome to code in.

[novel swallow]

Aye, it's a mess.

[red tiger]

Always newlines my ENTER taps.

It's Plato's Cave's take on IDEs.

Thanks, MacroHard.

[novel swallow]

Well, sat down and actually wrote a replacement TS version of what I'd done so far in lua and it's all working 👍

Good stuff, thanks for that

[red tiger]

Good stuff.

[novel swallow]

I'm still a little confused on arrays, as I've seen people say Lua is 1 based. But under the hood, Zomboid is Java...

I've seen some mods start at 1, and do < size + 1

To loop all recipes, I've done for (let i = 0; i < recipes.size(); i++) and it didn't blow up

[red tiger]

In TS, you should be fine staying with 0 throughout.

Unless whatever you're invoking is Lua-specific with a index param.

Also PZ Lua is not real Lua. It's Kahlua2 which emulates incomplete Lua 5.1.

[novel swallow]

Oooh, okay, noted.

[red tiger]

It was developed over 10 years ago with Java 1.6 technology.

[bronze yoke]

it depends on what you're interacting with

[red tiger]

It's utter trash.

[bronze yoke]

lua tables are 1 based (unless the developer is weird, which happens more than you'd expect), java objects are still 0 based

[red tiger]

This, but changes when working inside the TS environment.

TS is transpiled to 1 instead of 0.

(IIRC)

I could be absolutely lying since it's been a year since I made this.

https://typescripttolua.github.io/docs/caveats#array-length

This is all I could find ATM.

Either way you could write a quick test-case to test this out @novel swallow

Refer to the documentation on this website when you need to clarify any differences from a conventional JavaScript environment.

[novel swallow]

Yeah, I have a feeling this is going to be "do it 0 based till it errors" lol

[red tiger]

IMO The less time spent rewriting code for assumptions the better.

[novel swallow]

if I find something odd, I'll just end up wrapping it and using my wrapper anyway

[red tiger]

PipeWrench is a giant type-safe condom on PZ anyway.

lol

[novel swallow]

lol nice

that's what I needed really

[red tiger]

I can't imagine having to go through pure Lua and figure out what API change(s) broke my mods.

TS compile will tell you right away.

[novel swallow]

debugging lua and just... knowing what props/funcs are available was killing me after just an hour

no IDE/intellisense help either

it was like going back in time

[red tiger]

More people script than code in PZ so I shifted focus to writing the first full scripting support environment inside of VSCode for people to use.

I'm not really seeing much traction with that even though I have mentioned it a lot so I might shift back to PipeWrench. Who knows..

[novel swallow]

Is there a way to add recipes via code using PipeWrench?

I'm not a huge fan of them being .txt files 😅

[red tiger]

Would be cool to write an API for that.

Since it's a node environment that can be possible.

[novel swallow]

basically turn code in to the .txt files you mean?

[red tiger]

(Some flaws in this commit version but) https://github.com/asledgehammer/ZedScriptParser

I'm also a freak, btw.

lol

[red tiger]

This, yes.

https://github.com/asledgehammer/ZedScriptParser/tree/main/src/api/recipe

[novel swallow]

I mean it looks like you've written what I was planning to write, haha

Does JSON.stringify work in TypeScriptToLua? That'll help me with dumping out stuff for analysis

[red tiger]

No. That's why I wrote a Lua interface for a Lua library I modified to work in pz Lua.

.

@novel swallow

[novel swallow]

oh wow, you really have done everything I need 😂 thanks

[red tiger]

No problem.

[red tiger]

It's really funny how I'm just one dude with an itch to code properly and made all the stuff I linked. xP

You can make things so much easier and yet no one takes the bait to do good or even better with it.

[ancient grail]

I was thinking about the zed corpse
In some ways they are similar to manequins ..could the be a chance to add to their poses like what i did for the tha manequins
I wonder...?

[bronze yoke]

i don't think so, i think their pose is decided by a boolean

[novel swallow]

Hmm, is there a way to get fire rate of a gun? I don't see it on the base Item class

and now I'm doubting if the min/max damage of a gun is the melee damage or the projectile damage 🤔

[bronze yoke]

it should be on handweapon

[novel swallow]

How do I get that from Item?

[mellow frigate]

Are you aware of the differences between Item and InventoryItem classes ? Are you sure you are manipulating an Item instance ?

[bronze yoke]

oh, sorry, actually if you're on Item it should be there

i was thinking of InventoryItem

[novel swallow]

I'm filtering the result of getAllitems and I'm brand new to this so no idea 😅

[bronze yoke]

if there isn't a getter for it then you might actually need to make an instance to get it

i think it'd be called swingtime or something

[novel swallow]

Hmm I checked that but it doesn't seem to be representative

[bronze yoke]

it isn't, attack speed is heavily tied to animations

i don't know of any way to compensate for that

[ancient grail]

You could create another xml and the animation itself speed it up and do a boolean check for when the speed should be faster

[vale vapor]

Hello,

I need a little help if you can.

Events.OnZombieDead.Add(FunctionName)

This event work or not? I don't see anything.

[bronze yoke]

it works

[mellow frigate]

If you are interested in combat speed, as it is complex and messes with animation speed, I suggest you start by having a look at my mod on the topic. https://steamcommunity.com/sharedfiles/filedetails/?id=2864671032

[vale vapor]

ok thx. I will continue trying to see.

[novel swallow]

Does that stuff also apply to firing guns?

Hmm I guess the real question with guns I want is how long it takes to get an accurate shot, not fire rate 🤔

[bronze yoke]

i think that's referred to as aimingtime

[mellow frigate]

yes it applies to guns.

[red tiger]

I still need to know if I can get TIS to quickly add primitive numeric wrappers for Lua API.

I really shouldn't store bits / bytes as floats / doubles because Lua doesn't support primitives.

=/

We'd use so much less ram in PZ if mods could access these sorts of tools.

Also I would literally throw my example code on how to pass arbitrary uniforms to shaders in PZ if they'd implement either it or their take on it.

Controlling shader values from Java or Lua code is something that I'm sure a lot of people asked about over the years.

[reef rose]

hey. Does anybody know where the streetlight properties are hidden in the scripts? Where is it triggered on/off? thanks 🙂 Couldn't find anything related yet

[vale vapor]

if i write a print, where the print will come? in game on command console output log? Do you have other tips for see if my code is executed or not?

[red tiger]

debug mode has a console in-game. You can expose the game's command prompt by running it through CLI.

[vale vapor]

Yes i have this console, but i don't see my print on it. I'm spammed with many log.

[red tiger]

Then it's not firing.

Your code isn't executing.

Events.OnZombieDead.Add not addListener

[fast galleon]

also addListener?

addListener is from PipeWrench-Events API, not vanilla.

no zombies harmed during testing?

[red tiger]

PipeWrench implements more natural naming conventions for API.

[fast galleon]

I hook to this event to set them on fire so it should work.

ok, i'm doing a mistake i think. Don't work for me actually.

is this the entire file? maybe a syntax error earlier on is stopping this part from even being reached?

[vale vapor]

ok

Thx for your help Jab, albion and Poltergeist.

[novel swallow]

Hmm. I'm still struggling over here to turn an Item from getAllItems() in to a HandWeapon

Hand weapon has a constructor and I passed stuff in to it but... Then it doesn't seem to work properly.

[bronze yoke]

InventoryItemFactory.CreateItem(String itemType)

[novel swallow]

is itemType there getTypeString on the item?

[bronze yoke]

getName()

that's a little inconsistency, name usually refers to the translated name but on Item it's what's referred to as type everywhere else

[novel swallow]

ah I see

[bronze yoke]

getFullName() might be better

[novel swallow]

ooooh, you seem to be on to something 👀

Thanks

I've got more correct looking data coming out now (trying to glean stats from items)

[novel swallow]

When things say Time like AimingTime and ReloadTime, what unit is that?

Some kind of game tick? If I had to guess, it'd be like 60 ticks a second so a Time of 30 would be 0.5s

[bronze yoke]

it looks like seconds

hmm actually

[novel swallow]

Well this say reload time is 30 and it certainly doesn't feel that slow 😛

[bronze yoke]

ohh this works weird

the player's 'BeenMovingFor' increases 60 per second while moving and decreases 30 per second while not moving (clamping between 70 and 0)
if the player's BeenMovingFor is greater than aimingTime + their aiming level, it subtracts the difference from their hit chance

i think that's how it works anyway - if you sprint around for a really long time and it doesn't seem to take much longer then there might be more factors i'm not seeing

oh!!

i'm talking about aiming time and you're talking about reloadtime

i think reload time probably uses the same ticks as recipes/timed actions, which nobody seems to really know...?

[novel swallow]

Yeah, we're talking about different times BUT thank you for what you just mentioned as that is useful info to me as well 🙂

Oh wait, I was taking about both times! I assumed they were the same unit - but appears not.

[bronze yoke]

yeah, reload time should be timed action ticks (on top of a reloading speed modifier based on skill and probably panic and stuff?) but i've never heard how long they are

my reading of the code says they should be 1.25 seconds, which is blatantly wrong, but i can't find anything else relevant

[trim mist]

Polling for opinions:
I have an trait that subtracts endurance from the player every time they collide with an enemy. Problem is, the collide event triggers each tick until the enemy can no longer be collided with, subtracting ungodly amounts of endurance. I've already tried to mitigate this by storing the last collided with entity, and it works--for one player or zombie. A crowd is a problem, especially if you collide with two at once. So what should I do?

1. Store an array of entities the player has collided with and track the time since collided, removing them after ~1 second. Use this to compare instead of last entity collided with.
2. Create / find a different event that triggers only once in the process.
3. something else?

[trim mist]

by the way, I figured out how to stop the player from being bumped. You just need to set the bump type to "", a la

collider:setBumpType("");
collider:setBumpStaggered(false);
collider:setBumpFall(false);```
I know @ancient grail  was interested in this

[ancient grail]

Im already looking at your post

Just add a boolean moddata

[trim mist]

sorry I wasn't trying to @ you for your opinion, just to let you know that I figured out the bumping issue I was having yesterday. I remember you saying that figuring that out could be useful for you

but obv your ideas are appreciated

[ancient grail]

 if not zed:getModData().bumped then return end```

[bronze yoke]

you'd still need to remove it after a second

so it seems like keeping a lookup table would be better than going through moddata

[ancient grail]

I use vishnyas lua timer

[ancient grail]

Oooo enlighten us pls

[bronze yoke]

i'd like to look for a different solution though, could you just check if the zombie is currently falling/on the ground?

[trim mist]

I for some reason didn't think of this. There's something similar, one sec

[ancient grail]

You should follow albions advice instead
And use mine as a last resort

[trim mist]

in isoGameCharacter there's an isBumped. I'm not actually sure if the zombies get bumped or not, but I could set that too

[ancient grail]

That i believe is just for a short while? Does you collider have infinite energy

Can collide 100% all the time

How will it die

[trim mist]

no lmao. Once they can't sprint they're unable to do the event

which is bowling over a zomboid lmao

[ancient grail]

I see

[trim mist]

I'll post the code once I can get it to work flawlessly

[ancient grail]

Then check for endurance level instead

[trim mist]

or mostly flawlessly, at least

[trim mist]

here's what I'm checking for

[ancient grail]

U already made it so that it reduce enduranxe right?

[trim mist]

check if the collider is a player, if so, is it colliding with the previous entity it collided with? if not, then check if it has the right trait, if it's sprinting, and has been sprinting more than 10 (i'm unsure as to what unit of measurement this is, but it seems fine)

[ancient grail]

Sounds good

[trim mist]

I can add

and not collidee:isBumped()```
at the end of that second-to-last if and see if it works

[ancient grail]

Try it

[bronze yoke]

again, i wouldn't really use moddata for temporary data like this

local lastCollidedChr

local function ATOnCharacterColide(collider, collidee)
    ...
    if colidee ~= lastCollidedChr then
    ...
    lastCollidedChr = collidee
end

if you need splitscreen support you can make it a table indexed by player number instead

[ancient grail]

collidee

Hehe

[trim mist]

if you look at the event in the documentation it's really hard to tell who's the collider and not, so I made it easy for myself by fudging english a bit lol

[ancient grail]

If both are sprinting then yes

Ah that can be fixed easily
Just need to add

if  instanceof(zombie , "isoPlayer") then return end

[bronze yoke]

btw, just a style thing, but it can be a lot prettier to do if not condition then return end instead of if condition then if you're wrapping the entire rest of the function in that block

[trim mist]

I want to do this. Unfortunately I think I'm gonna need more explanation to do it? Other than being able to support splitscreen, what benefits are there to not using modData? At what point does this temporary data get cleared? Where exactly do I put the table, in the main lua script outside every function?

[ancient grail]

Weirdly enough i just gave this advice earlier

[trim mist]

I'm one of those people who love the
}
}
}
at the end of each function. I find it helps me keep my syntax straight if each if block is indented more

but I'll take a look at returning

[bronze yoke]

getModData() is a java function, so it's slower to call that than to just use a variable (though you could cache it to get around that), and a regular variable will be cleared whenever the game closes or lua is reloaded, instead of being saved as part of the save file

moddata would support splitscreen by default though

[bronze yoke]

if it's the style you're comfortable with you should keep it the way it is

if you wanted my way to support splitscreen you'd instead do```lua
local lastCollidedChars = {}

local function ATOnCharacterColide(collider, collidee)
...
local playerIndex = collider:getPlayerNum()
if colidee ~= lastCollidedChars[playerIndex] then
...
lastCollidedChars[playerIndex] = collidee
end

[trim mist]

Gotcha! I can understand that a lot better

Is there a way to make that table two-dimensional in lua? That's what I'd need to solve the current problem

...speaking of which, give me a moment to test the isBumped() idea

I've been looking at this chat nonstop lol

[bronze yoke]

yeah, you just put tables in the table

[novel swallow]

can I make an item than when you use it, grants a recipe and then is consumed?

Oh, that looks quite easy actually, nvm.

[trim mist]

still confirming if this works in tests but

just had to record this moment

[red tiger]

Gonna release mods under the banner "Team sledgehammer"

[red tiger]

Just gave two old laptops a new life, one by replacing a bad HDD and both by doubling LRAM. One now has Ubuntu.

[glass basalt]

does anyone know how many vehicle scenes there are in PZ? just wanna make sure I didn't miss any

[trim mist]

okay I have it working. Needs more testing from players over the long term, but it seems to work well for me!

Here's what I got: This will knock down zombies if you're sprinting at them with the appropriate trait, and only trigger the endurance reduction once!

local function ATOnCharacterCollide(collider, collidee)
    if instanceof(collider, "IsoPlayer")
    then
        -- take the sandbox cost, modify it by the difference between the player's current strength/fitness and the average strength/fitness of 5. Then turn that into a decimal since endurance is a decimal. Pick .01 if the cost is lower.
        -- if you ever figure out math, make it do a percentage taken away instead of a flat number
        local knockdownEndCost = Math.Max(SandboxVars.AnthroTraits.BullRushKnockdownEndCost - (((collider:getPerkLevel(Perks.Fitness) + collider:getPerkLevel(Perks.Strength)) - 10) / 100), .01)
        local colliderBehindCollidee = collidee:isFacingObject(collider, 0.5);
        if getDebug()
        then
            print("ATOnCharacterCollide Triggered");
        end
        if not collidee:isKnockedDown() and collider:HasTrait("AT_BullRush") and collider:isSprinting() and collider:getBeenSprintingFor() >= 10
        then
            if getDebug()
            then
                print("collidee: "..tostring(collidee));
