wesnoth.get_units with radius

[WhiteWolf]

Hi,

Sorry for the newbie lua question.
I'd like to use wesnoth.get_units to get an array of a units for in an area with a given radius around a tile. Something like:

Code: Select all

local inrange = wesnoth.get_units{x=27, y=10, radius=10}

But of course radius is not in SUF, it needs to go within a [filter_location] inside the SUF. What would be the syntax to achieve this? Unfortunately I've been unable to figure it out.
Thanks!

WML tag
[a]
b=c
[/a]
is written in Lua as {"a", {b="c"}}.

Got it, thank you!

No no no no no…

Ravana is technically correct, but I don't recommend doing what he said. It's confusing.

Instead, write it like this:

Code: Select all

wml.tag.a{b = "c"}

It expands to the exact same thing but is easier to understand what on earth it's doing.

So, to take your example:

Code: Select all

local inrange = wesnoth.get_units{x=27, y=10, wml.tag.filter_location{radius=10}}

It's also common to shorten wml.tag to just T by defining a local variable.
