Meowreka: /* Ripped Pocket */

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 [[WML_Utilities|Utilities]].

=== 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 macro ''OPPOSITE_SIDE''.

=== 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}

#define CHARM FILTER WEAPON
[event]
name=attacker_hits
first_time_only=no

[filter]

[/unstore_unit]
[/then]
)}
[/then]
)}
{NEXT i}

{CLEAR_VARIABLE possibly_charmed}
[/then]
)}
[/event]
#enddef

=== 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

[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.

To do this, use this code:

<code>#define WEAPON_SPECIAL_PICKPOCKET 
# Canned definition of the pickpocket ability to be included in a 
# [specials] clause.
# dummy weapon special used to describe the effect to the user
# and filter on special's id
[dummy]
id=weapon_pickpocket
name= _ "pickpocket"
name_inactive= _ "pickpocket"
description= _ "pickpocket :

description_inactive= _ "pickpocket :

apply_to=opponent
[/dummy]
[/specials]

# event that creates a "pickpocket has worked" variable
# and sets it to "yes" if the attacker hits at least once.
[event]

[/store_unit]
[set_variable]

value=yes
[/set_variable]
[unstore_unit]
variable=unit_att_with_pickpocket
[/unstore_unit]
{CLEAR_VARIABLE unit_att_with_pickpocket}
[/event]
[event]

[/unstore_unit]
[/then]
[/if]
{CLEAR_VARIABLE pickpocketer}
{CLEAR_VARIABLE pickpocketed}
[/event]
[+attack]
[+specials]
#enddef</code>

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
<code>[gold]
side=$side_number
amount='''X'''
[/gold]</code>
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
<code>[event]
'''name=attacker_hits'''
first_time_only=no</code>

to

<code>[event]
'''name=attack_end'''
first_time_only=no</code>

===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:
This unit gains an additional point added to its maximum damage whenever it kills a living unit."
[/dummy]

[/abilities]

first_time_only=no
[filter]

And the following in the unit's [abilities] tag:

{ABILITY_SOULTAKER}

===Charm (Type 2)===

An attack special. If the attack hits, and the target is level 0 or 1, the target is converted to the attacker's side. However, if it misses, the attacker is converted to the defender's side. Maintainer is krotop, using 1.6.x syntax (and compatible with 1.7.x], made for Melon's Youkai faction (http://www.wesnoth.org/forum/viewtopic.php?f=21&t=22539)

== 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).

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
<code>[gold]
side=$side_number

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
<code>[event]

to

<code>[event]

Meowreka: /* Ripped Pocket */

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 [[WML_Utilities|Utilities]].

=== Ripped Pocket ===

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}

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
<code>[gold]

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
<code>[event]
'''name=attacker_hits'''
first_time_only=no</code>

to

<code>[event]
'''name=attack_end'''

Meowreka: /* Ripped Pocket */

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 [[WML_Utilities|Utilities]].

=== Ripped Pocket ===

=== 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 macro ''OPPOSITE_SIDE''.

=== 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.

=== 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)}

=== 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:

<code>#define WEAPON_SPECIAL_PICKPOCKET

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
<code>[gold]
side=$side_number
amount='''X'''
[/gold]</code>
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
<code>[event]
'''name=attacker_hits'''
first_time_only=no</code>

to

<code>[event]
'''name=attack_end'''
first_time_only=no</code>

===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:

WML Abilities

2009-10-07T20:30:55Z

Meowreka: /* Ripped Pocket */

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 [[WML_Utilities|Utilities]].

=== Ripped Pocket ===

=== 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 macro ''OPPOSITE_SIDE''.

#define KNOCKBACK FILTER WEAPON
[event]
name=attacker_hits
first_time_only=no

[filter]
{FILTER}
[/filter]

[special_filter]

[store_locations]
x,y=$x2,$y2
terrain=AaBbDeLptUVvYZ
variable=defender_in_village
[/store_locations]
[if]
[have_unit]
x,y=$target_hex.x,$target_hex.y
[/have_unit]
[else]
{IF_VAR defender_in_village.length not_equals 1 (
[then]
{STORE_UNIT_VAR x,y=$x2,$y2 side side_of_defender}

[teleport]
[filter]
x,y=$x2,$y2
[/filter]

x,y=$target_hex.x,$target_hex.y
[/teleport]

[capture_village]
side=$side_of_defender
x,y=$target_hex.x,$target_hex.y
[/capture_village]

{CLEAR_VARIABLE side_of_defender}
[/then]
)}
[/else]
[/if]

{CLEAR_VARIABLE target_hex}
{CLEAR_VARIABLE defender_in_village}
[/event]
#enddef

=== 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}

#define CHARM FILTER WEAPON
[event]
name=attacker_hits
first_time_only=no

[filter]
{FILTER}

[then]
{MODIFY_UNIT x,y=$x2,$y2 variables.real_side $charmed_side}
{MODIFY_UNIT x,y=$x2,$y2 side $charmer_side}
{MODIFY_UNIT x,y=$x2,$y2 moves 1}
{MODIFY_UNIT x,y=$x2,$y2 attacks_left 1}

{VARIABLE_OP varname format "side_$charmed_side|_units_charmed"}
{VARIABLE $varname yes}

{CLEAR_VARIABLE varname}

{CLEAR_VARIABLE charmer_side}
{CLEAR_VARIABLE charmed_side}
[/event]

[event]

[/store_unit]

{FOREACH possibly_charmed i}
{VARIABLE_OP real_side format "0$possibly_charmed[$i].variables.real_side"}

{IF_VAR real_side not_equals "0" (
[then]
{IF_VAR side_number equals $possibly_charmed[$i].variables.real_side (
[then]
{CLEAR_VARIABLE possibly_charmed[$i].variables.real_side}
{VARIABLE possibly_charmed[$i].side $side_number}

[unstore_unit]
variable=possibly_charmed[$i]
find_vacant=no
[/unstore_unit]
[/then]
)}
[/then]
)}
{NEXT i}

{CLEAR_VARIABLE possibly_charmed}
[/then]
)}
[/event]
#enddef

=== 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

[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.

To do this, use this code:

<code>#define WEAPON_SPECIAL_PICKPOCKET 
# Canned definition of the pickpocket ability to be included in a 
# [specials] clause.
# dummy weapon special used to describe the effect to the user
# and filter on special's id

description_inactive= _ "pickpocket :

[/dummy]

[/gold]
[unstore_unit]

{COLOR_HEAL}
[/unstore_unit]
[/then]
[/if]
{CLEAR_VARIABLE pickpocketer}
{CLEAR_VARIABLE pickpocketed}
[/event]
[+attack]
[+specials]
#enddef</code>

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
<code>[gold]
side=$side_number
amount='''X'''
[/gold]</code>
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
<code>[event]
'''name=attacker_hits'''
first_time_only=no</code>

to

<code>[event]
'''name=attack_end'''
first_time_only=no</code>

===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:
This unit gains an additional point added to its maximum damage whenever it kills a living unit."
[/dummy]

And the following in the unit's [abilities] tag:

{ABILITY_SOULTAKER}

===Charm (Type 2)===

An attack special. If the attack hits, and the target is level 0 or 1, the target is converted to the attacker's side. However, if it misses, the attacker is converted to the defender's side. Maintainer is krotop, using 1.6.x syntax (and compatible with 1.7.x], made for Melon's Youkai faction (http://www.wesnoth.org/forum/viewtopic.php?f=21&t=22539)

=== 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)}

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:

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

#enddef</code>

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
<code>[gold]
side=$side_number
amount='''X'''
[/gold]</code>
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
<code>[event]
'''name=attacker_hits'''
first_time_only=no</code>

to

<code>[event]
'''name=attack_end'''
first_time_only=no</code>

===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:
This unit gains an additional point added to its maximum damage whenever it kills a living unit."

===Charm (Type 2)===

An attack special. If the attack hits, and the target is level 0 or 1, the target is converted to the attacker's side. However, if it misses, the attacker is converted to the defender's side.
