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] tag.

Abilities require macros found elsewhere in UsefulFragments, typically ProgammingMacros, Utilities, or Scenario Tools.

Knockback

When a unit is hit with a knockback attack, it is immediately pushed one hex away from the attacker, at which point the combat ends. Exception: units in villages can't be knocked out of them.

Examples that give knockback for every Drake Glider on their slam attack, and for the Shock Trooper named Jane:

{KNOCKBACK (type=Drake Glider) slam}
{KNOCKBACK description=Jane mace}

Requires the macros OPPOSITE_SIDE, IF, IF_HAVE_UNIT and STORE_UNIT_VAR.

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}

Requires the macros IF, STORE_UNIT_VAR and MODIFY_UNIT.

#define CHARM FILTER WEAPON

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.

Requires the macro MODIFY_UNIT.

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

        [filter_second]
            {FILTER}
        [/filter_second]

        {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 - say 10.

To do this, use this code:

#define WEAPON_SPECIAL_PICKPOCKET
[damage]
id=pickpocket
name="Pickpocket"
description="Pickpocket:
When used offensively, this attack gives 10 gold to the attacker on every successful hit." 
multiply=1
[/damage]
#enddef

Then put this event in your scenario:

[event]
	name=attacker_hits
	first_time_only=no
		[filter]
		side=$side_number
		canrecruit=1
		[/filter]
		[special_filter]
		weapon=pickpocket gloves
		[/special_filter]
		[gold]
		side=$side_number
		amount=10
		[/gold]
[/event]

Then give the unit you want to have the "pickpocket" special something like this:

[object]
silent=yes
	[effect]
		apply_to=new_attack 
		name=pickpocket gloves
		type=impact
		range=melee 
		damage=3
		number=3 
	 		 [specials]
	 			 {WEAPON_SPECIAL_PICKPOCKET}
	 		 [/specials]
	  [/effect]
[/object]
