Defense and abilities

[Picka79]

Hello!
I'm trying to create an ability who heals and increases by 10% the defense of adjacents mounted units (allies). I usually look at the abilities from the game to help me but there isn't any abilities which changes the defense.
I tried this, but it doesn't work :

Code: Select all

    [defense]
        id=test4
        value=-10
        [filter_base_value]
            greater_than=20
        [/filter_base_value]
        affect_allies=yes
        affect_enemies=no
        affect_self=no
        [affect_adjacent]
            adjacent=n,ne,se,s,sw,nw
            [filter]
                movement_type=mounted
            [/filter]
        [/affect_adjacent]
    [/defense]

Can you help me?

Sorry about my bad bad bad english

There is no simple way (as in, doable with ability tags alone) to do a defense-altering ability. In fact, I believe it's practically impossible in a way which would be reflected everywhere it needs to be in the interface; the best I can think of is giving every potential attacker's every attack an invisible weapon special which decreases their chance to hit. However, the improved defense would only show up in the damage calculations dialog, meaning that when moving your cavalry, the hexes next to the support unit would not display the improved defense value.

Thank's for your answer.

I am going to find another idea, because it is a little bit hard for me!



Hum, I have another question! I want that my unit give 1 exp point to adjacent units (when the units heal) but i don't know how to do that!

The simplest way would be to give every possible unit which could benefit from it an object which increases the defenses when an allied unit with that ability is adjacent.

e.g.

Code: Select all

    [event]
        name=turn refresh,recruit,recall,post advance
        first_time_only=no
        id=increase_defense_event

        [filter_condition] # do not fire this event without a reason
            [have_unit]
                [filter_wml]
                    movement_type=mounted
                [/filter_wml]
                [not]
                    [filter_wml]
                        [modifications]
                            [object]
                                custom_object_id=increases_defenses
                            [/object]
                        [/modifications]
                    [/filter_wml]
                [/not]
            [/have_unit]
        [/filter_condition]

        [store_unit]
            [filter] # any mounted units still without the object
                [filter_wml]
                    movement_type=mounted
                [/filter_wml]
                [not]
                    [filter_wml]
                        [modifications]
                            [object]
                                custom_object_id=increases_defenses
                            [/object]
                        [/modifications]
                    [/filter_wml]
                [/not]
            [/filter]
            variable=possible_targets
        [/store_unit]

        {FOREACH possible_targets i_temp}
            [object]
                silent=yes
                custom_object_id=increases_defenses # prevent the object being given more than once

                [filter]
                    id=$possible_targets[$i_temp].id
                [/filter]

                [effect] # apply this effect if an allied unit with said ability is adjacent
                    [filter]
                        [filter_adjacent]
                            ability=increase_defense
                            is_enemy=no
                        [/filter_adjacent]
                    [/filter]

                    apply_to=defense
                    replace=no
                    [defense] # all defenses which should be modified
                        shallow_water=-10
                        reef=-10
                        swamp_water=-10
                        flat=-10
                        sand=-10
                        forest=-10
                        hills=-10
                        #mountains=-10
                        village=-10
                        castle=-10
                        cave=-10
                        frozen=-10
                        fungus=-10
                    [/defense]
                [/effect]
            [/object]
        {NEXT i_temp}

        {CLEAR_VARIABLE possible_targets}
    [/event]

[zookeeper]

The simplest way would be to give every possible unit which could benefit from it an object which increases the defenses when an allied unit with that ability is adjacent.

Well, your code also makes the effect permanent. As opposed to abilities, an [effect] [filter] only selects whether or not to apply the effect at all, not when it should be "active".

[Dugi]

A working alternative would be to make no change to the terrain defence at all, but to add it a weapon special that decreases the opponent's chance to hit if the user is adjacent to a unit with that ability, something like this:

Code: Select all

[chance_to_hit]
  id=defended
  apply_to=opponent
  sub=10
  [filter_self]
     [filter_adjacent]
        ability=defend
        is_enemy=no
     [/filter_adjacent]
  [/filter_self]
[/chance_to_hit]

[Picka79]

Thank's Dugi!
Your method works perfectly!

[zookeeper]

Yeah, it works as long as they also have a ranged attack to give that special to. Otherwise, ranged attacks will hit them normally.

[Picka79]

I have a second question!

I'm trying to create an ability, "student", which give 1 exp at the beginning of the turn if an adjacent unit has the ability "teacher".

Code: Select all

#define ABILITY_STUDENT
    [dummy]
        id=student
    [/dummy]

    [abilities]
    [/abilities]

    [event]
        name=turn_refresh
        first_time_only=no
        [modify_unit]
            [filter]
                side=$side_number
                ability=student
                [filter_adjacent]
                    ability=teacher
                    side=$side_number
                [/filter_adjacent]
            [/filter]
            experience="$($this_unit.experience + 1)"
        [/modify_unit]
    [/event]
#enddef

Of course, that does not work. Can you help me?

When your current ABILITY_STUDENT macro is included in an [abilities] tag, like this:

Code: Select all

[abilities]
    {ABILITY_ABC}
    {ABILITY_STUDENT}
    {ABILITY_XYZ}
[/abilities]

It will expand to look like this:

Code: Select all

[abilities]
    {ABILITY_ABC}
    [dummy]
        id=student
    [/dummy]
    [abilities]
    [/abilities]
    [event]
        ...
    [/event]
    {ABILITY_XYZ}
[/abilities]

Whereas it should be written to expand to look like this:

Code: Select all

[abilities]
    {ABILITY_ABC}
    [dummy]
        id=student
    [/dummy]
[/abilities]
[event]
    ...
[/event]
[+abilities]
    {ABILITY_XYZ}
[/abilities]

So, the macro definition should look like this:

Code: Select all

#define ABILITY_STUDENT
    [dummy]
        id=student
    [/dummy]
[/abilities]
[event]
    ...
[/event]
[+abilities]
#enddef

[Picka79]

I tried your code but my unit won nothing
I doubtless made an error in [event].

My current code :

Code: Select all

#define ABILITY_STUDENT
    [dummy]
        id=student
    [/dummy]

    [/abilities]

    [event]
        name=turn_refresh
        first_time_only=no
        [modify_unit]
            [filter]
                side=$side_number
                ability=student
                [filter_adjacent]
                    ability=teacher
                    side=$side_number
                [/filter_adjacent]
            [/filter]
            experience="$($this_unit.experience + 1)"
        [/modify_unit]
    [/event]

[+abilities]

#enddef

name=turn_refresh -> name = turn refresh

[Picka79]

It always doesn't work!

[8680]

You may need to escape the variable and formula substitutions in experience="$($this_unit.experience + 1)" by adding vertical lines after the dollar signs (so it becomes experience="$|($|this_unit.experience + 1)").

This would be so that the variable and the formula will not be substituted by [event], but rather passed on to [modify_unit] — the variable $this_unit does not exist until [modify_unit] is running, so if it’s substituted before that, the formula would be + 1.

name=turn_refresh -> name = turn refresh

Low lines and spaces are interchangeable in [event]name.

Ah, didn't know that, I always just copy the wiki verbatim when possible.
