Short code tip needed

Let me know why is this happening >>>

and how setup (3) value

 

if I do 

inst:AddComponent("stackable")
inst.components.stackable.maxsize = TUNING.STACK_SIZE_SMALLITEM

 

code works

but if I do 

 

inst:AddComponent("stackable")
inst.components.stackable.maxsize =  3 

 

it goes to = 

[00:02:27]: [string "scripts/components/stackable_replica.lua"]:99: attempt to perform arithmetic on field '?' (a nil value) LUA ERROR stack traceback: scripts/components/stackable_replica.lua:99 in (method) SetMaxSize (Lua) <98-100>

 

FULL CODE - 

 

local assets=

{

Asset("ANIM","anim/coin.zip"),

Asset("ATLAS","images/inventoryimages/coin.xml"),

Asset("IMAGE","images/inventoryimages/coin.tex"),

}

 

local function fn()

local inst=CreateEntity()

 

inst.entity:AddTransform()

inst.entity:AddAnimState()

inst.entity:AddNetwork()

 

MakeInventoryPhysics(inst)

 

inst.AnimState:SetBank("coin")

inst.AnimState:SetBuild("coin")

inst.AnimState:PlayAnimation("idle")

 

inst.entity:SetPristine()

 

if not TheWorld.ismastersim then

return inst

end

 

inst:AddComponent("inspectable")

 

inst:AddComponent("inventoryitem")

inst.components.inventoryitem.atlasname="images/inventoryimages/coin.xml"

 

inst:AddComponent("stackable")

inst.components.stackable.maxsize = TUNING.STACK_SIZE_SMALLITEM

 

MakeHauntableLaunch(inst)

 

return inst

end

 

return Prefab("coin",fn,assets)

The value is used as an index in a table in stackable_replica.lua.

local STACK_SIZES =
{
    TUNING.STACK_SIZE_MEDITEM,
    TUNING.STACK_SIZE_SMALLITEM,
    TUNING.STACK_SIZE_LARGEITEM,
    TUNING.STACK_SIZE_TINYITEM,
    TUNING.STACK_SIZE_PELLET,
}
local STACK_SIZE_CODES = table.invert(STACK_SIZES)
...
function Stackable:SetMaxSize(maxsize)
    self._maxsize:set(STACK_SIZE_CODES[maxsize] - 1)
end

If your value isn't in that table, the function is attempting (nil - 1).

Hey Bumber64, it looks like you give me right way to go, but I`m still fresh in coding, so generally:

-should I study more about replica?

-should I push stacksize value I want to setup >  to global table?

-just let me know how to make maxsize = 3,

You'd need to put your value (3) in the STACK_SIZES table. You're going to have to include a modified copy of stackable_replica.lua with your mod (will break in the future if Klei makes their own changes, and you'll need to update your mod) or learn to upvalue hack (kind of complicated).

The table looks like it supports a max of 8 entries, because it's sending an index of 0-7 over the network. It seems to be used to support the Elastispacer resizing.
