Modifying CraftRecipe for modders is too unclear and limited, it needs us to use weird script overrides using Load or field reflection a lot of the time.
Adding a new tag to an item from Lua doesn't add this item to a craftRecipe inputs due to items with the tag being retrieved when loading scripts, which is done before Lua. The proposition would be to retrieve items from tags after loading Lua files which would make it better, or when loading a save.

Could the F11 debug menu, or something similar popup when we get a LUA compilation error when the game loads a save? (Maybe just in debug mode?) Even just a msgbox or something with the "Error on line 432 of yourfile.lua" text. Would save having to check the console.txt every time your game loads/watch for that brief 'error' popup as the game loads.

Request/Suggestion:
Uncap the max capacity of containers and character carry weight. Yes I know when setting it to something extra high it becomes weird with physics (at least, for cars), but adding those constraints just makes modding more annoying for modders. I still can come up with 3 ways to bypass it right now, but it's all weird and inconvenient solutions that don't need to be there.
TLDR: in base game people can't reach the hardcap anyway and modders can bypass it anyway, so it doesn't need to exist. Please remove it, so modders don't have to jump through extra hoops to do so.

Request
Please let the OnZombieUpdate event be called after super.update(). There are variables, such as the forward direction, that are assigned values in the super.update(). Which results into mods not being able to overwrite these values.
In my own mod I have an optional java mod that does this, and I haven't noticed any issues.
But it would be great if it were part of vanilla zomboid.

Sandbox option to disable culling in multiplayer.
Right now culling makes it impossible to have high zpop server because zombies disappear the moment player turns away.
Spawning a horde also fails half the time just for zombies to appear out of nowhere after returning to the area.
Player can clear the area and relog thinking it is safe just to appear in the middle of the horde.

Some recipes fail to complete the action when tags are used in input.
The crafting starts, gets to the very end of progress bar and nothing happens as if it was cancelled the very last moment.
The issues is hard to pinpoint and reproduce, some items matching tag in input work for recipe while others don't.
I spent hours trying to understand why it happens, it happens on different servers with different mods and with recipes from different mods, maybe it has something to do with the mods which adjust recipes through lua with Load() but then it also affects the recipes which are defined entirely in script file and are identical in syntax to vanilla game recipes, only "solution" I found is to replace i.e. tag[base:metalsaw] in a recipe with [Base.Saw], but recipe still can fail the same way when items are not in the inventory. Sorry for vague report, but issue exists and it is hard to tell what exactly happens.

getScriptManager():getAllCraftRecipes() returns empty table on client in multiplayer.
Doing something like this makes it run only on server:
local multiplier = 0.5
Events.OnInitGlobalModData.Add(function()
local scriptManager = getScriptManager()
local recipes = scriptManager:getAllCraftRecipes()
for i = 0, recipes:size() - 1 do
local recipe = recipes:get(i)
if recipe then
local name = recipe:getName()
local time = recipe:getTime()
if name and time then
local newTime = time * multiplier
if newTime < 1 then newTime = 1 end
recipe:Load(name, string.format("{ time = %d, }", newTime))
end
end
end
end)
After that some players see the change in crafting UI while others don't but for those who don't the timed action finishes midway the progress bar which means it still uses the modified time.
Overriding time through script files directly works just fine.

Getting SandboxVars during OnInitGlobalModData on client returns default values for options instead of the values set on the server.

Enable the ability for mappers to define custom jumbo trees. It seems it's just out of reach as we can create custom tiles with jumbo tree sizes in TileZed, but not be able to implement them in any way (at least in any workshop-friendly way) due to the larger trees only able to be defined as elements in NatureTrees.class.
We can sort of define new ones using the stuff provided in WorldGen/features/tree, but they don't appear to detect any custom tile from my testing in late 2025.
HUGE mapping potential if this is unlocked. As it stands, we're only able to replace vanilla jumbo trees, but it's not ideal if you want more trees than the initial few available.

writeLog handle collision during simultaneous session startup.
When running a local server and client on same cache folder, both instances can initialize at the exact same second. This causes the PZ runtime to generate identical log filenames (e.g., 2026-03-01_19-01-00_ModLog.txt). The first process locks the file, causing the second process to lose its write handle, resulting in missing debug logs.

The server does not give Lua a chance to say "yes" or "no" before a container changes.
When a client moves an item, the server's Java code handles it directly. Lua is not asked first. There's no hook like:
"Before moving this item, should we allow it?"
ISInventoryTransferAction is client-side only (unavailable on server). Vanilla code requirement causes a require failed (shared/ISInventoryTransferUtil.lua).
On server-side, ISTransferAction:transferItem is exclusively called by Transactions.dropOnFloor.

About once a day, some new modder falls victim to the fact that you need a translation tag for an item to have >0 weight. Can this 'feature' please be removed as its confusing? If its required somewhere for items to have no weight (I don't know anywhere in vanilla that uses this and I'm not sure why weight=0 would not suffice, it seems to be a throwback from when items without a translation would not show up at all in inventories, a feature I believe we now completely lack?), some kinda boolean would be better and less confusing.

Think we could get some built-in methods for region zone based zombie outfit and container overrides, kind of like the professionvehicles lua file?
Ideally it'd be built in to existing lua files.
Examples:
Distributions lua
PoliceLockers = {rolls = 4, Rosewood(RegionZone) = { "Rosewood-Item", 2,}, Generic = {"Generic-Item", 2,}, items = { "Normal-Item", 2,},
This basically defines 3 categories. A region zone. A generic fallback. And the normal items.
Whereas when populating loot, it will add what's in the region zone category if the container's in said region zone. If not, it will fall back to Generic.
The existing "items" category is just added alongside the zone specific stuff.
This should also be able to apply to vehicle trunks and gloveboxes/seats/etc.
We could also take this a step further and apply it to zombie outfits as well.
Say in zombieszonedefinitions lua:
table.insert(ZombiesZoneDefinition.Default,{name = "Generic01", replace={"Generic02"}});
This would replace "Generic02" zombies with "Generic01" zombies in the "Default" definition. (Globally, pretty much.)
Anyhoo, I wish you fellas the absolute best! Good luck with B42.

REQUEST
Can project zomboid please clear its zombie folder on version change? I ask as a java modder.
Reason: Most java mods don't allow the game to load a save or fully launch when loaded by the wrong version of zomboid (Expected behavior). This is now a problem with B42.13/B42.14 because they no longer overwrite files there on validate/update of the game, so people who install the mod and switch versions don't get it automatically uninstalled anymore and can no longer load the game until they manually delete the zombie folder (And many forget it exists after a month of playing with a mod). Validation no longer fixes the issue as of B42.13/14.
Alternatively (I prefer this idea), could the zombie folder be renamed to something like.. 42.14.1\zombie (updated to match version number of course) And this would provide even better compatibility and easier install of java mods across multiple version of zomboid? (While automatically preventing zomboid from trying to load the wrong version java mod when it updates/changes version)
This would result in reduction of java mod related bug reports to TIS and improve overall player experience.

You get the idea.",
instead of adding UI_ETW_DelayedNotificationsStringRemove___note_to_translators it would be very convenient to have a comment.

I assume these were locked under debug for security concerns, but would it be possible to replace these with something more secure?

There's a lot of cases where something is exposed but doesn't have a getter - and it's insanely useful to be able to at least read the value.

Please expose IsoSpriteManager.namedMap (a read-only copy would be fine).
Water Goes Bad previously used this to find tiles with specific properties and add MapObjects listeners for them spawning. This allowed it to catch valid objects spawning without using massively inefficient methods like scanning every object during LoadGridsquare. This does not seem to be possible anymore: you can get sprites with a specific name but not a list of all sprites.
---@type string[]
local waterObjectSprites = {}
---@type table<string, IsoSprite>
---@diagnostic disable-next-line: undefined-field
local sprites = transformIntoKahluaTable(spriteManager.namedMap --[[@as HashMap<string, IsoSprite>]])
for name, sprite in pairs(sprites) do
if sprite:getProperties():has(IsoFlagType.waterPiped) then

I forgot to request this, but parts of the recipe system aren't exposed entirely so once you start drilling into them with Lua you can't get certain objects.
Also, related, ParseScript() which allowed modders to generate a script in real time using only Lua seems to have been blocked unintentionally as now the world dictionary locks once written to.
My particular use case was creating a recipe that could be changed via sandbox option (parsed string on load).

Not sure if this is worth reporting - I personally wouldn't address it but:
If you use getActivatedMods():contains() in .14 you needed to add the slash- which broke now for .15. I know you made an effort to support the slash for the time being so thought you should know, @main rose

Make it possible to attach animals with rope to objects whose sprite has the CanAttachAnimal prop but is not in the specialObjects.
Right now if I do for example:

"appliances_com_01_94",

local function addAttachmentFlag()
local sprites = HorseHitching.Sprites
for i = 1, #sprites do
local name = sprites[i]
local spr = getSprite(name)

Duplicating an object from the objects to the specialObjects causes world corrupting bugs.

Add some kind of "required mods" validation on server updates.

The 42.15 update blocks access to reflection, which causes problems for mods that were using reflection to get around a lack of API features. For Wear Anything With Anything, this breaks the mod when not running in debug mode.
I would like to request that the BodyLocation provides a way to clear the exclusion list, as the class allows adding new exclusions but not removing them or getting a full list of exclusions.

WorldMapStreetsV1:getAllStreets() returning an array of WorldMapStreet and WorldMapStreet:getPoints() returning an array of StreetPoints and exposing the various getters in StreetPoints would be perfect.
I can convert streets.xml into a lua table, but that will not work with map mods

The ability to have more than one animated mesh on an entity would open up many possibilities. For example; the current implementation for horse manes in the Horse Mod is just attaching several simple objects onto deformation bones which can look... rudimentary.
If we were able to have additional meshes that deform to the same armature, we could implement a much more rich and detailed system for customizing manes and tails. This would also potentially allow for deforming armor, saddles, and other forms of equipment. And I'm sure that being able to have multiple animated meshes would help many other people as well.
Obviously, it's not a simple request, but I thought that I should put this out there.

API Request: Secondary Lua Worker Thread API
I cannot currently use PZ to encrypt my network traffic effectively so using SHA256 encryption is not possible. (Even with emulated Bitwise Operations in Lua 5.1)
I could render graphics and perform tasks that could return as callback promises through a very simple API that could register worker tasks in a sort-of pooled solution that could offload these tasks to prevent stalling the game's main thread. This would open up more complex mods like advanced anti-cheats written by communities or advanced mods that requires a lot of processing in-game to function and provide cool features.

Request.
Context: I was making accessibility patch which renames Keen Hearing to Keen Perception and allows to take it together with Hard of Hearing or Deaf.
Keen Hearing is a must have trait when playing with sprinters and even with it people who have hearing issues are still at disadvantage. Such change levels the ground a bit and also allows regular players to experience deaf characters without impacting the vision.
The issue is that Hard of Hearing stacked with Keen Hearing reduces the rear visibility by 1 tile (~5 tiles -> ~4 tiles), Deaf doesn't do that.
Without Keen Hearing there is no real difference in distance at which zombies become visible from behind between Hard of Hearing and Deaf (~3 tiles).
It would be nice if neither Hard of Hearing nor Deaf would further reduce the rear visibility, there's no need for that from both gameplay and accessibility standpoint.
(In b41 there was visual indicators mod which was targeting people with hearing issues but it did hurt the experience more than it helped because of the screen pollution it caused when there was too many noise sources around. As a result people with hearing issues didn't use it at all and people who have normal hearing abused it as zombie radar lol)

Use case: server-side anti-cheat for ESP/wallhack detection. The most common PZ cheats patch the Java jar or inject via javaagent - the ESP rendering happens inside PZ's GL pipeline, so
glReadPixels (used by takeScreenshot) captures it. Screenshots are the hardest thing for cheats to fake - spoofing glReadPixels requires re-rendering a clean frame, which is far more complex than
hooking a simple hash function.
This doesn't expand the Lua sandbox - takeScreenshot() already captures the full game window. It just writes to a directory Lua can't access.
Suggested solutions (any would work):
The cleanest option is probably readScreenPixels() since it avoids filesystem entirely and gives modders exactly what they need - pixel data from the current frame.

I’m working on a larger Java-side mod that interacts with Project Zomboid’s local SQLite database, and wanted to ask if there are any plans to expose an official API or bridge for modders to access these databases (especially things like the player table).
Right now I’ve implemented my own solution using a Java agent, custom loader, and bridge layer to execute database queries and expose methods back to Lua. It works, but it’s obviously a custom approach, so I’d prefer to align with an official system if something like that is planned.
For context, my current setup is roughly:
• Java agent injects into the PZ JVM
• Loader discovers and initializes backend modules
• Bridge exposes Java methods to Lua
• SQLite is accessed directly via JDBC for reads/writes
My main goal is to reliably access player-related data (IDs, etc.) so I can build additional server-side systems and tables tied to those primary keys.
Totally understand if this isn’t on the roadmap, just wanted to check before going further down this path. Happy to share more details if helpful.
Direction of this has slightly changed to be more encompassing but, relative point/question still remains.

Could you, if possible, reintroduce the option for ambient sounds in B42? It seems to have been removed in B42 (Not an option anymore under Audio/Sounds) and, if I understand correctly, is now clamped in the Java Core. Sound design and ambient sound suppression for certain mods were a key part of the workflow; whilst this hasn’t completely disappeared, as a modder you now have very few options to suppress the standard ambient sounds and play your own ambient sounds for a specific area instead.
You can still play them, but they blend in with the maximum ambient sounds around you - which is a mixed result, at best.

sly solar
Completing on the previous requests regarding the sounds on the main menu, there is in general a serious lack of sound volume handling for mods, the current system doesn't allow sounds to be automatically managed by the sound options of the game.
This is absolutely terrible as often modders will either adjust the volume of the sounds they play to their personal settings because they don't realize the game doesn't automatically handles the volume and so they think the problem is their sound file.
Or we end up having to reprogram a whole volume handling system just to play sounds at proper user sound settings, often having to add our own sound bars to a mod option or to hijack the sound options to add an extra volume bar for our own mods.
This is becoming a serious problem, especially considering there's a category parameter for sound scripts which should be handling all of that for us, but right now it doesn't do anything and every modders end up having to add a whole sound system to their mods just to play one or more sounds.
This is notably something we had to do for the Horse mod with a sound system which adjusts the Horse volume based on distance from the player, based on user settings, based on the material the horse walks on etc.

When an IsoThumpable object is created from the building menu, it's going to create the thumpable taking from the entity scripts data. One of the things it does is GameEntityFactory.instanceComponents on the new entity with the entity scripts data to properly initialize the different components. This will call CreateComponentFromScript which for FluidContainer components will set the value fillsWithCleanWater to the current script value.
When there's a FluidContainer component on an entity being loaded from a save with load, fillsWithCleanWater does not get set. This means that any time a rain collector gets created with the fillsWithCleanWater to true, it will not be set back to true when reloading the save

I am not a fan of registries.lua as that file literally is lua thus one can just run any lua codes in it. Given that many modders in the community hate OSS aka strong sense of ownerships to the codes and assets aka will dcma anyone for forking. Thus to mod the mod (like how modder mod the base game), you will have to use those mods as dependency. However, registries.lua cannot be overriden thus modders literally can do all kind of bs in it including bs that break the game thus you can never ever write patch to such a mod without forking a complete standalone.

Patching up every function call that writes to disk one-by-one is good, but if the game's executable could not write to anywhere outside specific low-security folders that would be even better.

Suggestion: rework 0-100% condition-based DrainableComboItems like gas mask/respirator filters to store their condition in a normalized state, independent of its specific value of "useDelta"
I tried to make a simple mod to provide a sandbox option to scale filter durability, but found that the obvious methods for changing "useDelta" don't affect the durability of filters already in-world. if you spawn a gasmask filter (at 100% condition), reduce its useDelta from 0.01 to 0.005 in an OnInitGlobalModData event, and reenter the game, you'll find that same filter now at 50% condition. that 50% is consumed at the new useDelta rate, but its total lifespan is the same as it was before. new items are correct
despite references to "usedDelta" in the java that can report the condition as a fraction between zero and one, my guess is that the actual stored quantity is effectively "remaining number of integer uses" (in effect, initialized at item creation to 1/useDelta and integrally decremented, rather than initializing to 1 and reducing by useDelta). because the original useDelta is baked into the item's state, it means that we don't have an easy way to affect the capacity of items already in the world, and that the obvious parameter has not-obvious caveats

Zomboid doesn't load ActionGroups from mods, even thought it is supposed to. The main problem of it is because the game only looks for the files inside the game's canon path and ignore mods. Even though mods have listeners that trigger actiongroups reloading when messing around with the files, and a path for the folder.
zombie.characters.action.ActionGroup
private void load() {
String name = this.name;
DebugType.ActionSystem.debugln("Loading ActionGroup: %s", name);

File folder = ZomboidFileSystem.instance.getMediaFile("actiongroups/" + name);

if (listOfFiles != null) {

if (stateFolder.isDirectory()) {
ActionState state = this.getOrCreate(stateFolder.getName());
String statepath = stateFolder.getPath();
state.load(statepath);
}
}
}
}
The main culprit is the method of ZomboidFileSystem.instance.getMediaFile() that only checks the path of the game main folder, but not mods. An alternative would be ZomboidFileSystem.instance.resolveAllDirectories() that takes mods into account (Be ware that it returns an array of strings instead of a File).
If you wishf for a proper proof that this was actually supposed to happen. You can look at the info that mods store at zombie.gameStates.ChooseGameInfo, and look at the Mod class.
public static final class Mod {
..
public final ZomboidFileSystem.PZModFolder actionGroupsFile = new ZomboidFileSystem.PZModFolder();

This was overlooked ever since B41...
Fixing this would allow modders to add their own custom states and alliviate some of the workarounds needed for animations. Maybe it would make it easier to add animals. Or even a swimming mod would actually be possible to create.

Okay, this is a funny one. Aiming at skeletons with a gun crashes the game. 
This video shows the crash, by spawning some skeletons through modding.
And well, after spending way too much time trying to debug it, I've found the issue. Turns out, it mainly happens at zombie.core.physics.BallisticsTarget, more specifically at:
private void updateSkeleton() {
this.getBoneTransforms();
Bullet.updateBallisticsTargetSkeleton(this.getID(), this.numberOfBones, boneTransformData);
}
However, why does it crash? BECAUSE THE SKELETONS HAVE A DIFFERENT SKELETON ARMATURE!!! Turns out, the models Female_Skeleton and Male_Skeleton have these pesky leaf bones called Nub on them, while the main models of the game misses them. And that makes the call for Bullet.updateBallisticsTargetSkeleton() try to handle bone structure of the skeleton with the normal humans THAT DON'T HAVE Nub BONES! Winch results in the game dereferecing a NULL pointer at PZBullet64.dll (At least that's what I assume).
Which leaves us with two way of fixing this.
Add a guardrail on PZBullet64.dll at updateBallisticsTargetSkeleton() to verify if boneTransformData[i] (I presume) is a NULL pointer, and prevent the crash.
Just remove the Nub from skeletons. WHICH I DID! Here's another video of the crash being fixed!
This bug probably happens with mods too if the modmaker doesn't know the ideal bone structure for the models. The same thing might occur if any model have a different in the bones comparing to other. Might be useful to add this Info to the wiki as a desclaimer for modders.

newState.set = this;
this.states.put(stateName.toLowerCase(Locale.ENGLISH), newState);
}
return true;
}
The main problem here is that listOfDirs only receives relative paths of every file, including the paths for mods. The issue is that the function has no idea if a relative path is from a mod or not, so it scans only the game's directory, and not the mod's directory.
If you go to the ZomboidFileSystem.instance.resolveAllDirectories() and follow its path, you will notice that the main culprit is actually walkGameAndModFiles() and its closure, the function never includes the actual absolute path of the mod file and always uses their relative path.
public String[] resolveAllDirectories(String relPath, FileFilter filter, boolean recursive) {
ArrayList<String> result = new ArrayList<>();
//The closure its used at (file, relPath2) doesn't have any context of the real path.
this.walkGameAndModFiles(relPath, recursive, (file, relPath2) -> {
if (file.isDirectory() && filter.accept(file)) {
String relPath3 = relPath2 + "/" + file.getName();
if (!result.contains(relPath3)) {
result.add(relPath3);
}
}
});
return result.toArray(new String[0]);
}
Following the path you will spot that the closure finally receives its file and path at walkGameAndModFilesInternal()
public void walkGameAndModFiles(String relPath, boolean recursive, ZomboidFileSystem.IWalkFilesVisitor consumer) {
this.walkGameAndModFilesInternal(this.base.canonicalFile, relPath, recursive, consumer);
ArrayList<String> modIDs = this.getModIDs();
for (int n = 0; n < modIDs.size(); n++) {
String modID = modIDs.get(n);
ChooseGameInfo.Mod mod = ChooseGameInfo.getAvailableModDetails(modID);
if (mod != null) {
this.walkGameAndModFilesInternal(new File(mod.getCommonDir()), relPath, recursive, consumer);
this.walkGameAndModFilesInternal(new File(mod.getVersionDir()), relPath, recursive, consumer);
}
}
}
private void walkGameAndModFilesInternal(File rootFile, String relPath, boolean recursive, ZomboidFileSystem.IWalkFilesVisitor consumer) {
File fo = new File(rootFile, relPath);
if (fo.isDirectory()) {
File[] list = fo.listFiles();
if (list != null) {
for (File listedFile : list) {
consumer.visit(listedFile, relPath); //<-- The closure finally gets its values here.
if (recursive && listedFile.isDirectory()) {
this.walkGameAndModFilesInternal(rootFile, relPath + "/" + listedFile.getName(), true, consumer);
}
}
}
}
}
The only way I can think of solving this issue right now, is simply transforming the relative path into an absolute one when we are dealing with mods. I've made a silly fix for this that I am not really sure if it can fix it, but it was my way to solve it.
All it essentially does is add one more parameter to the function so it prepends the rootfile along with the relative to get its absolute path. (Only now I am seeing I could just keep pasting text files in here instead of making a mess, MY BAD!)
There's probably a better way to do this... oh well, it is what it is.
This would also kinda fix resolveAllDirectories() to be used for other ocassions instead of just AnimationSet

ZomboidFileSystem.validatePrefix rejects valid Workshop mod paths intermittently at boot. Build 42.
Symptom: Workshop mods that load FBX animations (or any asset that goes through validatePrefix) sometimes fail to load on launch. Once it manifests, the affected content stays broken for the entire session — players have to relaunch or resub one or more times to land on a "good" boot.
Repro: subscribe to a Workshop mod that ships custom anim FBXs (e.g. SaucedCarts, Workshop ID 3651954650), launch PZ. Bug rate is small per launch but reproducible across sessions.
Stack trace:
WARN : General > AnimationAssetManager.loadCallback > Failed to load asset: AssetPath{ "bob/_bob_cart_walk" }

Path is genuinely a subscribed Workshop content folder. Should pass validation.
Diagnosis: validatePrefix checks inputPath.startsWith against a lazily-built List<Path> allowedPrefixes. The supplier calls getAllModFolders, which memoizes a List<String> modFolders field populated ONCE from three sources: SteamWorkshop.GetInstalledItemFolders (subscribed Workshop), SteamWorkshop.getStageFolders + /Contents/mods (staged Workshop), and <myDocs>/Zomboid/mods/.
When SteamWorkshop.GetInstalledItemFolders returns an incomplete array on its first poll (Steam client cache state at PZ startup), modFolders is permanently cached missing one or more legit mods. allowedPrefixes derives from that partial list. Every subsequent validatePrefix call for an asset under the missing mod throws — neither modFolders nor allowedPrefixes is refreshed under the throw path, so the failure persists for the session.
Suggested fix: on validatePrefix rejection, retry once after calling the existing public resetModFolders() (line ~428) — which nulls modFolders and resets the allowedPrefixes lazy. If the path is still invalid after a fresh re-enumeration, throw as before. No security boundary change; uses an already-existing method.
Code refs (line numbers from a recent decompile; live build's validatePrefix is at line 1658 with identical logic):

Request: release AnimZed
"Why?"
y'all have expressed wanting to release it in the past.
having access to this tool would be revolutionary for the modding community.
accessing this tool would limit the need for extensive java modding: eg. rewriting zomboid's api to work with non-zomboid assets.
currently, the only alternative to AnimZed involves folks making their own custom tools. this entails significant time investment. not everyone has the coding experience/knowledge to pull this off.
there are no community tools which achieve anything similar to AnimZed.

Request: Expose a way to link callbacks to AnimEvents on specific action states to allow better use of custom events.
This initially was supposed to be request to make occurredAnimEvents from ActionContext readable through IsoGameCharacter since reflection is dead, and so it could ease the workarounds needed for custom animations event on other states, and create a quick check in Lua to see if it was triggered. But then I realized that there could be a better option for this problem, which is to create a proper way to link callbacks to events when on a specific action state.
Because right now the main way to do such a thing is to use SetVariable on XMLs, check them in Lua, and then call ClearVariable() to clear them. But that's adds a lot of overhead, and clutters the variables of the character (as they don't delete the variable just empties them). Not to mention that it isn't really precise enough, which adds ever more jankiness to mods.
And, even though TimedActions can be used to have such functionality on the go, they can't be used on all places (ESPECIALLY FOR ZOMBIES AND ANIMALS), and aren't the best alternative when it comes to fluid animations. Essentially TimedActions has a luxury that every state could have, but doesn't...
This might be a hefty request, but it would great QOL for mods in general.

request:
A way to "attach" multiple models visually to an item (similar to weapon attachments but without the need for parts and such - this is a request for a purely visual system)- could be useful for a number of reasons, and I'm not familiar with a way to do it outside of weapon attachments - or toggling parts of a model (Vehicles allow this, not sure if items do).
Use case: I want to eliminate the need of having dozens of objects in my game-night mod but I also want to prioritize the game-in-progress being visible in the world. But I can also imagine this would be useful for a number of things.

By default every sound scripts should use the Primary master volume but it turns out that the methods we use to play sounds (IsoGameCharacter.playSound) end up calling the function in the linked file (which is a snippet from FMODSoundEmitter) by passing var2 as equal to 1.0F, which is the reason why volume settings don't impact modded sounds being manually played.

Request/suggestion 2
support for different items installed on vehicle parts to have different models, similar to what modders have done using LUA.
example: if you want "brake old" and "brake performance" to have two different models attached to them they currently will just both show at the same time (again, unless youve written your own code) i think that i would be quite beneficial for it to, not be that way

#HEADLESS CLIENT.
Having code that allows a connection from another dedicated server to connect as a virtual client and then take over computations of Zombies and Loot. This would free up many bottle necks, and make 32+ players servers more common. Look into Headless Clients from Arma 3. I coded many mission that had a server tick rate of 5 to 45 [50 Max at the time] and AI reacted better, could be modded to do behaviors only a headless client can achieve. I have been looking through Java for a year with little progress. I love optimizing, this would be an easy instant optimization. Sure it requires a bit of setup, but its worth it.
Representing the 305 btw 😄

It would also be super nice to have a getter for ObjectRenderInfo.targetAlpha since it appears this is one of the big indicators for if an object, ie a floor/roof above, is "cutaway" to expose what is behind it when the player is close enough.
There is already IsoObject.getRenderInfo but there isn't any way to check the values outside of debug.

IsoPlayer:getSteamID() returns a Java long that loses precision when accessed from Lua in Build 42. Steam ID 76561198042221333 becomes 76561198042221328 or 76561198042221330 depending on the formatting method used, because Kahlua converts the 64-bit long to a Lua number before the script can access it.
Tested approaches (all produce incorrect values):
Also tested:
Expected: A way to get the full-precision Steam ID as a string from server-side Lua. The correct value (76561198042221333) exists in the server's SQLite database (db/KLICKALACK.db, whitelist table, steamid column), confirming the data is available internally.
Request:
Expose a getSteamIDAsString() method on IsoPlayer, or fix getSteamIDFromUsername() to work on the server side, so mods can reliably identify players by their Steam ID.

FixingManager.getFixes needs to check for getRequiredItem() to be valid before calling contains
Any mod that adds an invalid fixing recipe will provoke an error on right clicking the Hood part (and many other parts) of any vehicle.
The error will not point towards the failed FixingRecipe nor the associated mod.
There are many un-updated mods in B42 provoking that bug, including the famous CommonSense. The number of unaware players complaining on mod_support in huge. Most of them never get the right explanation because the error is obscure.

Recipes that use a varied # in the input line only use 1 hunger value of each item consumed in the recipe unless itemcount is present, then it uses the full item.
item 1 [72:Base.Tomato;24:Base.CannedTomato_Open;48:Base.CannedTomatoOpen] flags[IsExclusive],
I have also tried:
item 72 [Base.Tomato;24:Base.CannedTomato_Open;48:Base.CannedTomatoOpen] flags[IsExclusive],
So the 6 tomatoes used in this recipe, all came back to me with only one hunger value taken from each.
It would be nice to specify the amount of hunger used rather than whole items, and have that varied in the input. Not sure if it's a bug or a request.

`LearnableRecipes` parameter for literature items does not allow recipe...
You simply can't refer to the recipes by their full ID but it does find recipes in different modules. This is a bit inconsistent with everything else in scripts where if they are in the Base module then they are found easily bcs it checks in Base then imports (sometimes?), and if the module is provided in the script reference then it finds it. Here providing any module (be it Base or a custom module), the recipe will not be recognized
