[Solved] Accessing [store_gold], etc, directly

[white_haired_uncle]

Hoping this is a dumb question...

Code: Select all

wml.fire("store_gold",{variable="trader_menu_gold"})  -- ugly, fix me
local gold=wml.variables["trader_menu_gold"]

This works, but it means using a wml variable with no guarantee it's not clobbering something existing.

I've seen another way of calling events (not wml.fire), don't have an example right now unfortunately, but I never could get the syntax right.


P.S. Is there any way to get this search engine (or any other on earth) to search for something like "store_gold"? Everything I've tried searches for "store" (splitting store_gold into "store" and "gold" and then ignoring gold because it's too common, even though that's NOT what I asked for).

TIA

I didn't test it, but you should be able to write local gold = wesnoth.sides.get(1).gold. Here https://wiki.wesnoth.org/LuaAPI/types/side you cen see which other attributes can be read that way

Works great, thanks. And thanks for the link as well.

Example to show the other syntax

Code: Select all

wml.variables.x = "abc"

wesnoth.wml_actions.message{message="$x"}

wml.fire("message", {message="$x"})
wesnoth.wml_actions.message(wml.tovconfig{message="$x"})
wesnoth.wml_actions.message(wml.interpolate({message="$x"}, wml.all_variables))
wesnoth.wml_actions.message(wml.interpolate({message="$x"}, {x = wml.variables.x}))

I couldn't find a way I liked to get the current side. Since I was more or less in a moveto event, I knew I could use a specific unit, but I'm less than thrilled with this.

Code: Select all

local side_number = wesnoth.sides.find{ wml.tag.has_unit { x=cfg.x,y=cfg.y }}[1].side

$side_number?

[Ravana]

As Lua, wml.variables.side_number. There is also something like wesnoth.current.side, but I dont remember if that is what you are supposed to use as LuaAPI.

You can certainly use it, (Its documented in https://wiki.wesnoth.org/LuaAPI/wesnoth#wesnoth.current and commonly used in mainline, for example in World conquest). so the code would looks like wesnoth.sides[wesnoth.current.side].gold or wesnoth.sides.get(wesnoth.current.side).gold

[Celtic_Minstrel]

wesnoth.current.side returns the current active side, which is probably what you want, but if you actually wanted the side of the unit involved where it might not be on the active side, you could also use wesnoth.variables.unit.side or wesnoth.variables.second_unit.side.
