[1.1.107]The API function get_script_inventories() is not returning any value.

[Deadexow]

What did you do?
I simply entered the command

Code: Select all

/c local inv = game.create_inventory(16) local invs = game.get_script_inventories() game.print(invs[1])

in the command box.

What happened?
It only returns

nil

, which does not align with the return value described in your API documentation.

What did you do next?
I entered the command

Code: Select all

/c local inv = game.create_inventory(16) local invs = game.get_script_inventories(inv.mod_owner) game.print(invs[1])

in the command box

What happened?
It only print

Cannot execute command.Error:Unknown mod:core

• What did you expect to happen instead?

I wish to get the inv that I created using create_inventory() through the function get_script_inventories() or others.

Does it happen always, once, or sometimes?
This issue can be reproduced easily by following my steps anytimes.

I simply entered the command

Inventories created through console commands will be owned by "core".

[Deadexow]

Regardless of whether I use the command console or a module to call this function, the return value of this function is always an empty table.
Furthermore, when I use the command console command game.get_script_inventories("core"), this function results in an error, as previously demonstrated. Consequently, I am unable to retrieve the inv created by game.create_inventory() through any function again.

Return values
→ dictionary[string → array[LuaInventory]]
A mapping of mod name to array of inventories owned by that mod.

I mean, I can't be sure, but from your first command, I'd expect game.print(invs[1]) to be nil.

Try a for loop with pairs and see what you get out of that.

Code: Select all

for k, v in pairs(invs) do
    game.print("key, value: " .. k .. ", " .. v)
end

(Assuming I didn't typo anything.)

(Edit: I'm wondering if game.print(invs["core"]) is actually what you need? But try the loop, first, before deciding that there is actually nothing there.)

Correct.

Try a for loop with pairs and see what you get out of that.

Code: Select all

for k, v in pairs(invs) do
    game.print("key, value: " .. k .. ", " .. v)
end

(Assuming I didn't typo anything.)

This wouldn't work. For each mod you'll get an array of inventories (where each inventory is an array of LuaItemStack objects), so game.print() will error with "string expected, got table".

(Edit: I'm wondering if game.print(invs["core"]) is actually what you need? But try the loop, first, before deciding that there is actually nothing there.)

It will work if you loop over the inventories in invs["core"]. Try this on the console:

Code: Select all

 /c test = game.create_inventory(16)
 invs = game.get_script_inventories()
 for i, inv in pairs(invs.core) do
   game.print(string.format("%s %s of mod \"%s\", %s slots %s", inv.object_name, i, inv.mod_owner, #inv, tostring(inv.is_empty() and "(empty)" or inv.is_full() and "(full)" or "")))
 end

Yeah, I was wondering about that while writing it. I was posting from my phone and wouldn't have access to the game until, well, now. So conceivably, running the loop just printing the value of 'k' would have been enough to prove that something was there, or wrapping 'v' with tostring():

Code: Select all

/c local inv = game.create_inventory(16) local invs = game.get_script_inventories() for k, v in pairs(invs) do game.print("key, value: " .. k .. ", " .. tostring(v)) end

Edit: Could also use serpent on 'v':

Thank you very much,now I know what the function return:

Code: Select all

{
	["mod_name"] = {inv,inv,……},
	["mod_name"] = {inv,inv,……},
}
