[Is there a way to modify the attribute of an item that already spawned?]

You might be able to use the Event system: https://pzwiki.net/wiki/Modding:Lua_Events

 

Not sure which event would be best, OnPlayerUpdate perhaps?  Then check the players inventory for a tool box, however I expect that event runs a lot so it might be excessive for something like this.

Thanks for the link!

 

I noticed the OnGameStart event, which I first saw from looking at Item Tweaker API's code.

 

I think this or OnLoad would have the least overhead, but I'd still need a way to pull an array with all the toolboxes (or items spawned) in the current game. Optionally, I would save the name of the game file to to a text file so it only runs one time per game. The problem is getting an array with the items, which I don't know how to go about.

 

The OnPlayerUpdate would be easier since I'd just have to check the player's inventory and I'm sure getting the player's inventory is better documented. The problem would be the overhead, which would be excessive and unnecessary.

 

So now the next step is, how to get an array of all the world items to loop through them and setWeightReduction.

 

If you  happen to know a method that returns the items in the world, I would be grateful if you could share it. In the meantime, I'll be looking around to see if such a method exists.

[Is there a way to modify the attribute of an item that already spawned?]

I thought that maybe someone in the workshop might have this figured out so I looked around for other weight reduction mods.

 

The only workaround I've found is someone who added a crafting recipe where you use the old item to craft a new item of the same type, which then has the changed attribute.

 

If it's not possible to change the attribute of a spawned item, this will have to suffice.

Would this work?

Thanks. I've known about that method and have looked through the code base for statements that call setWeightReduction (link), but I'm not sure how I would implement it.

 

I was thinking I'd need to loop through all Toolboxes in the game and then call setWeightReduction, but I don't know the name of the array (or what method I can call that returns an array of all spawned toolboxes).

 

I also figured that maybe the toolbox attributes where saved in the game files once they spawned so it might not even be possible.

this mod modifies the item definition that is used at item spawn time.

It will never modify an already spawned item.

You need something else to modify the item already spawned.

Thanks. Can you point me in the right direction?

[Is there a way to modify the attribute of an item that already spawned?]

I want to modify the Weight Reduction of the Toolbox.

 

I'm using Item Tweaker API.

 

The changes doesn't take effect in a currently saved game, but it does work in a new game.

 

Does anyone know how to get it to work for toolboxes that have already spawned?

The vanilla function is in /server/ rather than /client/, so you should probably do likewise.

If that doesn't fix it, can you post the stack trace from the console?

 

Thanks for the response.

 

The TL;DR is that I switched the file to the "server" folder and renamed it to something other than "recipecode.lua" and it worked.

 

---

 

With the above in mind,  before changing the folder name and renaming the file, I checked console.txt and saw errors like "indexing null table UpgradeSpear" and that it also couldn't find other functions that were related to recipecode.lua

 

I figured the mod was replacing the original recipecode.lua and renamed it. I didn't check if changing the folder name had any effect on it, I'll get to that later and post back.

[First time creating a mod. I'm trying to override Recipe.OnCreate.UpgradeSpear, but get "Error 0" when loading into saved game.]

 

Folder structure (not sure if this is correct):

mods/Better Spear Upgrade/media/lua/client/recipecode.lua

 

mod.info file:

 

name=Better Spear Upgrade
poster=
id=BetterSpearUpgrade
description=Changes the formula for the starting condition of an upgraded spear
url=

 

Code:

 

local _orig_UpgradeSpear = Recipe.OnCreate.UpgradeSpear

-- get a mix of spear & upgrade item to do a correct condition of the result
-- we take the craftedSpear condition and substract the attached weapon condition

function Recipe.OnCreate.UpgradeSpear(items, result, player, selectedItem)
  local spearCondition      = 0
  local spearConditionMax   = 0
  local weaponCondition     = 0
  local weaponConditionMax  = 0
  
  local conditionMax = 0;
  for i=0,items:size() - 1 do
      if items:get(i):getType() == "SpearCrafted" then
          spearCondition    = items:get(i):getCondition()
          spearConditionMax = items:get(i):getConditionMax()

      end
  end
  
  for i=0,items:size() - 1 do
      if instanceof (items:get(i), "HandWeapon") and items:get(i):getType() ~= "SpearCrafted" then
          weaponCondition     = items:get(i):getCondition()
          weaponConditionMax  = items:get(i):getConditionMax()
      end
  end
  
  local conditionPct  = ((spearCondition / spearConditionMax) + (weaponCondition / weaponConditionMax)) / 2
  conditionMax        = result:getConditionMax() * conditionPct
  
  if conditionMax > result:getConditionMax() then
      conditionMax = result:getConditionMax();
  end
  if conditionMax < 2 then
      conditionMax = 2;
  end

  result:setCondition(conditionMax);
end

 

[Need help understanding Recipe.OnCreate.UpgradeSpear]

Thanks man, it was just the 3 items.

[Need help understanding Recipe.OnCreate.UpgradeSpear]

My question is about the "items" parameter: is it all the items in the player's inventory or just the Crafted Spear or Hand Weapon that the player selected?

 

I left the code snippet below for your convenience.

 

-- get a mix of spear & upgrade item to do a correct condition of the result
-- we take the craftedSpear condition and substract the attached weapon condition
function Recipe.OnCreate.UpgradeSpear(items, result, player, selectedItem)
    local conditionMax = 0;
    for i=0,items:size() - 1 do
        if items:get(i):getType() == "SpearCrafted" then
            conditionMax = items:get(i):getCondition()
        end
    end
    
    for i=0,items:size() - 1 do
        if instanceof (items:get(i), "HandWeapon") and items:get(i):getType() ~= "SpearCrafted" then
            conditionMax = conditionMax - ((items:get(i):getConditionMax() - items:get(i):getCondition())/2)
        end
    end
    
    if conditionMax > result:getConditionMax() then
        conditionMax = result:getConditionMax();
    end
    if conditionMax < 2 then
        conditionMax = 2;
    end

    result:setCondition(conditionMax);
end

 

[[41.71] Ingredient images for meals inside a cooking container are small]

I figured this is just how the game renders them and was trying to mod it to make it bigger, but someone suggested that I report this as a bug.

 

I was told to include my font settings, so here they are:

 

UI:

 * Inventory Container Button Size: Large

 

Fonts:

 * Font Size: 3x

 * Context Menu Font: Large

 * Inventory Font: Large

 * Tooltip Font: Large

 

 

 

[Does anyone know how I can increase the size of the ingredient images? I'd be willing to write the mod myself but I don't know where to begin.]

[How do I check whether an item is a spice?]

EDIT: the function I was looking for is isSpice.

 

So:

 

item:IsSpice()

 

I found the function using this link: https://projectzomboid.com/modding/

 

------

 

I'm trying to modify the AutoCook mod to exclude spices.

 

Relevant section of code (I think). The last line in particular is where I would add the check to see if the item is a spice, but I don't know the function to call on the item object for checking its spice value.

 

function AutoCook:chooseItem(items,baseItem, recipe)
    if AutoCook.Verbose then print ("AutoCook:chooseItem "..baseItem:getName()) end
    if not items or items:size() == 0 then--if there is no more available items stop auto cook
        return nil
    end
