[closed] Where is current attack weapon stored/how it's marked?

[ZombieKnight]

Hi
I can't find where the current attack weapon is in the data structure (while attacking).

[ZombieKnight]

(The existing code)

Code: Select all

local function printTable(table, indent)
    indent = indent or 0
    for key, value in pairs(table) do
        if type(value) == "table" then
            std_print(string.rep("  ", indent) .. key .. ":\n")
            printTable(value, indent + 1)
        else
            std_print(string.rep("  ", indent) .. key .. ": " .. tostring(value) .. "\n")
        end
    end
end
printTable(wml.variables["unit[0].attack[0]"])

(prints units first attack)

Thanks,
thats what I'm looking for but I can't find it when I use

Code: Select all

printTable(wml)

I can't see it there (tryied even with [inspect] inside attacker hits event).
Is it stored somewhere else?

[Ravana]

Automatically stored variables are only stored into variable during first time you access it. Example https://github.com/ProditorMagnus/Agele ... e.cfg#L125

Thanks!

[ZombieKnight]

It works!

Ravana has linked you to the wrong wiki page. What you're looking for is documented here. Specifically, you're looking for wesnoth.current.event_context.weapon and/or wesnoth.current.event_context.second_weapon.

The way Ravana described is the WML way. It'll still work to use that in Lua, but it's not the Lua way.

[ZombieKnight]

Oh thanks, I'm new to wesnoth lua...
I'm actually using the "wml." way a lot is it wrong?

[Celtic_Minstrel]

It's not technically wrong. It's probably less efficient or something, though that rarely actually matters. If you use wml.variables.unit or whatever, the weapon needs to be serialized into a WML variable, which normally takes a little bit of time. If you use wesnoth.current.event_context.unit, I believe it just gives you the Lua unit proxy without serializing anything. It probably makes less of a difference with weapon, as from what I recall that's just a WML table anyway.

[ZombieKnight]

Whats event_context and current.event_context?
What it's stored in wesnoth.? (are there stored even on-board units?)

[Celtic_Minstrel]

wesnoth.current.event_context is all the information about the currently-running event.

I don't understand what the second line of your post means.

[ZombieKnight]

Are there stored on-board units in wesnoth.?
If they are, can I change things saved there(directly, using lua, not store/unstore unit)

[Ravana]

As soon as you store it, you do not have unit anymore, you have copy of its wml.

In Lua there is support for proxy units which let you change without storing. https://wiki.wesnoth.org/LuaAPI/wesnoth ... .transform has example.

[ZombieKnight]

Thanks, so

Code: Select all

 wesnoth.units.transform(my_unit_stored_from_map, "Ghoul") 

changes a on-map unit that has same x,y as a unit stored in my_unit_stored_from_map to type Ghoul?
Or has every parameter to be exactly same as the on-map unit?
