WML Abilities

Remember that you must include the WML ability code in every scenario where you intend them to work. Or include them in the unit file inside the [unit_type] tag.

Some abilities require macros from Utilities.

Knockback

When a unit is hit with a knockback attack, it is immediately pushed back one hex away from the attacker. Units cannot be knocked back into an occupied hex, out of villages or onto terrain they normally could not move to. Only works on offense.

Use this to display the special correctly on the attacks you want:

   #define WEAPON_SPECIAL_KNOCKBACK
       [dummy]
           id=knockback
           name= _ "knockback"
           female_name= _ "female^knockback"
           description=_ "Knockback:
   When a unit is hit with a knockback attack, it is immediately pushed back one hex away from the attacker. Units cannot be knocked back into an occupied hex, out of villages or onto terrain they normally could not move to. Only works on offense."
       [/dummy]
   #enddef

And insert this event to your [scenario], [multiplayer], [unit_type] or [era]:

   [event]
       name=attacker hits

Charm

When a unit is hit with a charm attack, it instantly jumps to the attacker's side, and returns to it's original side at the beginning of that side's turn. A charmed unit has 1 movement point and can attack.

Example that makes all Troll Whelps have charm on their attack:

{CHARM (type=Troll Whelp) fist}

Bloodlust

Bloodlust is a very simple ability. If a unit that has bloodlust kills an enemy unit when attacking, it may attack again, provided that there are more enemy units adjacent to it.

This would give the bloodlust ability to all Dwarvish Ulfserkers (making them insanely powerful):

{BLOODLUST (type=Dwarvish Ulfserker)}

#define BLOODLUST FILTER
    [event]
        name=die
        first_time_only=no

        {MODIFY_UNIT x,y=$x2,$y2 moves 0}
        {MODIFY_UNIT x,y=$x2,$y2 attacks_left 1}
    [/event]
#enddef

Pickpocket

This special could also be called loot. When a unit with this attack special sucessfully hits an enemy unit, it gains a certain amount of gold.

To do this, use this code:

#define WEAPON_SPECIAL_PICKPOCKET

# [specials] clause.
# dummy weapon special used to describe the effect to the user
# and filter on special's id

It can be placed after the [unit_type] tag, or in its own .cfg file.

To change the amount of gold given per hit, change

   [gold]
   side=$side_number
   amount=X
   [/gold]

Where X is the amount of gold you want.

If you want the gold to be constant, given at the end of the turn if at least one of the attack hits, instead of X amount of gold per hit, change

[event]
  name=attacker_hits
  first_time_only=no

to

[event]

Soultaker

Any unit with this ability will gain an additional point of damage per strike every time it kills an enemy. Coder(s) unknown, made for Melon's Youkai faction (http://www.wesnoth.org/forum/viewtopic.php?f=19&t=20100).

To give a unit the ability, place the following in any .cfg file loaded by the campaign or era:

#define ABILITY_SOULTAKER
	[dummy]
		id=soultaker
		name= _ "soultaker"
		description=_ "Soultaker:

Works

Unit with ability works will produce 1 gold per turn.

Put this macro into you code before the last piece of code.

#define ABILITY_WORKS

Put this event into your code.

Mind Flay

The weapon special gives an attacker 1 point of exp taken from a defender for each hit. This will violate minimum experience (i.e. defender can go below 0).

Give this special to the attack(s) you want it to have.

Immune to drain or plague or poison

This macro will grant immunity to drain for a unit. By changing a few specials' names and ability names, you can easily expand it for an immunity to plague or drain. This will not work properly if there is a unit with multiple weapon specials that might be affected (plague+drain, poison+plague, poison+drain, poison+drain+plague), in this case, it will grant immunity to all of them.

Whirlwind Attack

This attack is supposed to be an attack when you spin with your weapons in arms, hitting all nearby enemies, while they cannot counter. It should be used with the magical weapon special, because the spinning weapons are not easy to dodge and the player would pick to attack the unit with the lowest defence without it. It works with drain, slow and poison weapon specials. The attack is supposed to be attack-only, but it can be easily edited to work also on defence.

This is a pair of two macros, one is a weapon special that makes the enemy unable to counter (lowers the number of attacks by 10; for the case if there was a boss or something). The other one is an event that damages the units, that should be placed into every scenario where the unit appears (or the era), preferably through a macro.

This is the part that is the weapon special that marks it.

       name= _ "whirlwind"
