Count units on a side?

[LordAwsomeness]

is there a way to count the units on a side? specifically units that have a static effect such as poisoned or slowed?

[josteph]

Code: Select all

[lua]
    code = << wml.variables.foo = #wesnoth.get_units { side=1, wml.tag.filter_wml { wml.tag.status { poisoned='yes' } } } >>
[/lua]

and then access the WML variable $foo.

[lua]
    wml.variables.foo = #wesnoth.get_units { side=1, wml.tag.filter_wml { wml.tag.status { poisoned='yes' } } }
[/lua]

and then access the WML variable $foo.

I am unfamiliar with integrating lua into wml. do I need to just copy and paste that lua syntax or do I have to do something more?

[josteph]

You can't just paste lua syntax into WML, you have to wrap it in [lua] tags. [lua] tags are ActionWML and can be used wherever ActionWML is allowed, like inside events and menu items and so on.

I edited the previous post to correct a syntax error, make sure to use the new version.

You can store units in WML as well and check length.

Also, filter_wml is not needed for status anymore since 1.12 I think.

oh interesting. what would I use to check the wml instead of filter wml?

status: (Version 1.13.0 and later only) matches if the unit has the specified status active. This can be a comma-separated list, in which case the unit will match as long as it has one of the listed statuses active
