Fixed Crafting With Multi-Use Items 1.5.2 addon

Installation: Just drag and drop gamedata folder in Stalker Anomaly directory.

v1.0:

Release

V2.0:

RERELEASED. Fixed my own fix. Now it should work properly completely. Previously, changing the amount had also affected other part amount requirements. Now there is a separate variable just for multi-use items.

v2.2: fixed separate variable change

v2.3: Included patch for artifax's Weapon Parts Overhaul

v2.4: Included patch for artifax's Outfit Parts and Repair Overhaul

v2.5: Kinda tidied folder a little. Gave Main + Weapon Parts Overhaul + Outfit Parts and Repair Overhaul patch its own folder.

v2.6 Updated to 1.5.2 and now relatively conflict free! Should be compatible with WPO, OPO and any other script that makes changes to ui_workshop.script

!!!EXPLANATION ONE!!!
When crafting with multi-use items, the number of uses your item contains is supposed to be negated by the amount required.
However that is not the case.

///////////
-- to discharge
if count > amount then
self.craft_item_remain[n] = { id = id , cnt = (count - amount) }
break
end
///////////

self.craft_item_remain's second index (cnt = (count - amount)) defines how many times the multi use item is supposed to be discharged.

"count" is the number of uses your supporting item has, while "amount" is SUPPOSED to be the amount of uses that get discharged for the craft.
Unfortunately, there's a mistake here. If you have a 5 use item (count = 5) and the amount of uses
required for the craft is 3 uses (amount = 3), cnt will actually equal how many uses ITS SUPPOSED TO HAVE LEFT.
But incorrectly, cnt ends up being the number of uses that get discharged.
So 5 - 3, the multi-use item gets discharged TWO times.
And now you're left with 3 uses left out of the 5. Allowing you to use the item for crafting again!
It's supposed to be discharged 3 times, with 2 uses left out of the 5.

The code below executes the number of times the multi-use item discharges, "cnt" times.

///////////
if obj_itm and cnt then
print_ws("- UIWorkshopCraft:Craft() | discharge item (%s) [%s] %s times", id_r, obj_itm:section(), cnt)
for k=1,cnt do
utils_item.discharge(obj_itm)
end
//////////

So I fixed the code so that the number of times the multi-use item is discharged is the current
number of uses (count), minus the number of uses its supposed to have left (count - dischargeAmount).
!!!So the resultant number = the number of times the code will discharge the item.!!!
if count > amount then

//////////
...local dischargeAmount = amount...
self.craft_item_remain[n] = { id = id , cnt = (count - (count - dischargeAmount)) }
break
end
//////////

This fixes the logic error created, and so forth correctly discharges the correct amount of the multi-use item. I added a separate variable, "dischargeAmount" so that the actual amount variable does not charge.

!!!EXPLANATION TWO!!!
When crafting with MULTIPLE multi-use items, the game just DELETES one of the items.

//////////
count = 0
for id,cnt in pairs(parts_id) do
count = count + cnt

-- to delete
if (count <= amount) then
self.craft_item[n][#self.craft_item[n] + 1] = id
end

if count == amount then
break
end
//////////

Using this script logic, it scans the number of uses for the first multi-use has.
When crafting, you have a use requirement of 3, and you have two multi-use items. One multi-use item has 1 use, while the other item has 3 uses.
You have 4 uses in total, and so you meet the crafting requirement with ONE use extra.
Executing the crafting script, if the crafting script uses the multi-use item with 1 use, and THEN the multi-use item with 3 uses, you should have a multi-use item with one use left right?
Unfortunately, no.
The script logic above detects the multi-use item with 1 use left, and just DELETES IT, not having it contribute to the amount of uses left for crafting.
So the first multi-use item with 1 use just gets deleted,
and so forth onto the next multi-use item.
The next multi-use item has 3 uses, since the amount required still equals 3 uses, that item gets deleted too, and the crafting script is over.

You see the problem here, you should have been left with one multi-use item with one use left.
Your one multi-use item with one use did NOT contribute to how many uses the requirement amount is left.

So I fixed the problem by changing the code.

//////////
-- to delete
if (count <= amount) then
self.craft_item[n][#self.craft_item[n] + 1] = id
dischargeAmount = dischargeAmount - count
end
//////////

As you see here, when one of the multi-use items in the crafting process is less than the required amount, it gets deleted,
and now REDUCES THE REQUIRED AMOUNT LEFT (USING A SEPARATE VARIABLE EQUIVALENT TO PREVIOUS AMOUNT VARIABLE) ACCORDING TO HOW MANY USES THAT ITEM HAD.
So now when you have a use requirement amount of 3,
inputting one multi-use item with 1 use, and another one with 3 uses,

The multi-use item with 1 use gets used up, the required amount left is 2, the second multi-use item with 3 uses gets used up TWO times now, leaving 1 remaining use on that item.

You will now get back one multi-use item with 1 use left, because your total of uses met the requirement, and the correct amount of uses has been used up in total.

Good hunting.
