Is there any way to filter units without ability?

[Quetzalcoatl]

Is there any way to filter units without ability? I was looking for it at wiki and forums but didn't find anything.
For example I would like to store units that doesn't have submerge or regeneration.

What I'm trying to do is to heal unit when all other units heals (between turn start and turn refresh).
I thought the best solution would be to modify unit at turn start (give regenerates) and remove this ability at turn refresh.

http://wiki.wesnoth.org/StandardUnitFilter lists ability id as something you can filter. So...

Code: Select all

[filter]
	[not]
		ability=regenerates
	[/not]
[/filter]

[Sapient]

Code: Select all

[filter]
  [not]
    ability=submerge
    [or]
      ability=regenerates
    [/or]
  [/not]
[/filter]

you can invert matches by using the [not] sub-tag.

Thx , somehow i missed it

Here is the WML that do healing between turn start and turn refresh (that means no problems with labels, healing animations, regeneration and such - maybe it would be useful for somebody else):

Code: Select all

    [event]
        name=side turn
        first_time_only=no
        
        {VARIABLE south_rune_used no}
        [object]
            silent=yes
            [filter]
                side=$side_number
                x,y=9,18
                [not]
                    ability=regenerates
                [/not]
            [/filter]
            [then]
                {VARIABLE south_rune_used yes}
            [/then]
            [effect]
                apply_to=new_ability
                [abilities]
                    {ABILITY_REGENERATES}
                [/abilities]
            [/effect]
        [/object]
    [/event]
    
    [event]
        name=turn refresh
        first_time_only=no
        
        [if]
            [variable]
                name=south_rune_used
                equals=yes
            [/variable]
            [then]
                [object]
                    silent=yes
                    [filter]
                        side=$side_number
                        x,y=9,18
                    [/filter]
                    [effect]
                        apply_to=remove_ability
                        [abilities]
                            {ABILITY_REGENERATES}
                        [/abilities]
                    [/effect]
                [/object]
            [/then]
        [/if]
        {CLEAN_VARIABLE south_rune_used}
    [/event]

This will do healing exactly like village on any x y hex.

ah, very clever.

you should add this to the Useful WML Snippets page on the wiki

Thx , somehow i missed it

Here is the WML that do healing between turn start and turn refresh (that means no problems with labels, healing animations, regeneration and such - maybe it would be useful for somebody else):

Code: Select all

...

I did not try this, but doesn't this remove the regeneration ability from units that already have them?

Good point. Something like this should fix that:

Code: Select all

            [effect]
                apply_to=new_ability
                [abilities]
                    {ABILITY_REGENERATES}
                    [+regenerate]
                        id=fakeregenerates
                    [/regenerate]
                [/abilities]
            [/effect]

Code: Select all

                    [effect]
                        apply_to=remove_ability
                        [abilities]
                            id=fakeregenerates
                        [/abilities]
                    [/effect]

It doesn't remove any attributes form units that have it already Thats why I asked how to filter units without ability However regeneration with fake id its a lot better solution than having temp variables and extra conditions and I wasn't aware before that this can be done that way.

So here is the updated WML (as macro this time):

Code: Select all

#define HEALING_PLACE X Y
    [event]
        name=side turn
        first_time_only=no
        
        [object]
            silent=yes
            [filter]
                side=$side_number
                x,y={X},{Y}
            [/filter]
            [effect]
                apply_to=new_ability
                [abilities]
                    {ABILITY_REGENERATES}
                    [+regenerate]
                        id=fake_regenerates
                    [/regenerate]
                [/abilities]
            [/effect]
        [/object]
    [/event]
    
    [event]
        name=turn refresh
        first_time_only=no
        
        [object]
            silent=yes
            [filter]
                side=$side_number
                x,y={X},{Y}
            [/filter]
            [effect]
                apply_to=remove_ability
                [abilities]
                    [regenerate]
                        id=fake_regenerates
                    [/regenerate]
                [/abilities]
            [/effect]
        [/object]
    [/event]

I will try to post this on wiki sometime soon.
