[micro_ai] error: bad argument #1 to 'insert' (table expected, got nil)

[WhiteWolf]

Hello,

I'm trying to make some scattered animals behave like animals with the [micro_ai] ai_type=forest_animals setting. Here's the code:

Code: Select all

[event]
    name=prestart
    
		[micro_ai]
			ca_id=jonadiszno
			side=3
			action=add
			ai_type=forest_animals
			rabbit_type="Rabbit TRS"
			deer_type="Stag TRS"
			tusker_type="Horse TRS,Boar TRS"
			tusklet_type="Chicken TRS,Pig TRS"
			rabbit_hole_img="scenery/dirt.png"
			[filter_location]
				[not]
					x=1-30
					y=1-11
				[/not]
			[/filter_location]
		[/micro_ai]
[/event]

The unit types are valid, and the scattered units are on the map. Yet, each time it's side 3's turn, after a few moves, this error happens:

error

What am I doing wrong?


EDIT:
These are the lines the error is pointing to in ca_forest_animals_move.cfg:

Code: Select all

    -- If cfg.rabbit_hole_img is set, only items with that image or halo count as holes
    local holes
    if cfg.rabbit_hole_img then
        for _,item in ipairs(all_items) do
            if (item.image == cfg.rabbit_hole_img) or (item.halo == cfg.rabbit_hole_img) then
                table.insert(holes, item)
            end
        end
    else
        holes = all_items
    end

Apparently it doesn't see the items? There are numerous

Code: Select all

[item]
     x,y=...
     image=scenery/dirt.png
[/item]

items on the map, I don't see why the micro_ai doesn't find them.

I think the fix would be to write local holes = {} on the second line of your posted code snippet (naturally that would be a bug in the AI if so, but you can make the change yourself for a quick test).

[mattsc]

Yes, that's it, and it is already fixed, but only from Wesnoth 1.14.6 on, while it looks like you're using 1.14.5.

[WhiteWolf]

Oh, I see. Yes, sadly 1.14.5 is still the newest with my linux distribution, and I'm not great at compiling from source.
Guess I'll use an #ifver for the custom rabbit hole then

[Ravana]

It is Lua change, no compiling needed. You can open the file and change it yourself.

That is if you need it for yourself, for other players if you want to support lower versions you need workarounds.

[mattsc]

Also, since the entire Micro AI is written in Lua, you could add a local, fixed version of the MAI to your campaign and use that. Then it becomes independent of the version a player uses. Might not be worth the effort though.

You can install 1.14.7 via flatpak if you are using Ubuntu. http://ubuntuhandbook.org/index.php/201 ... o-install/

I already handfixed it here, but that's the point, for if anyone is still using 1.14.5 or older for some reason, it'd be broken for them, that's why I decided to use an ifver condition. It's also less effort than trying to include the entire MAI in the campaign. But that's another option, could be done some time later. Thanks

It's Debian 8 sadly.

Flatpak is supposed to be distro-agnostic, so it can be installed on Debian as well, depending on if Debian 8 supports it.
