StandardSideFilter
From The Battle for Wesnoth Wiki
From FilterWML, this is the standard way of filtering on sides. The following attributes and sub-tags are permitted:
- side: filter matches only if side number is contained in a comma-separated list. 'all' matches all sides.
- [has_unit]: filter matches only if side controls a unit matched by this StandardUnitFilter
Also, [and], [or], and [not] subfilters are supported.
Interaction of SSF and side= in tags like [allow_recruit] :
selects side 4 only :
[allow_recruit] side=1,4 [filter_side] side=4,5 [/filter_side] [/allow_recruit]
selects sides 1 and 4
[allow_recruit] side=1,4 [/allow_recruit]
select sides 4 and 5
[allow_recruit] [filter_side] side=4,5 [/filter_side] [/allow_recruit]
