== Examples ==

==== Battle ====
Let's say you want to trigger different events based on the output of the fight:
* <code>is variable_set battle_last_result:won</code>
or
* <code>is variable_set battle_last_result:lost</code>

==== Date ====
Let's say you want to trigger an event in a specific date (mom's birthday, anniversary, etc.), eg. on the 25th May (day nr 145 or 146 if leap year or not):
* <code>is variable_set day_of_year:146</code>
* <code>is variable_set leap_year:true</code>
or
* <code>is variable_set day_of_year:145</code>
* <code>is variable_set leap_year:false</code>
but if the specific date is before (included) the 28th February (day nr 59):
* <code>is variable_set day_of_year:59</code>

==== Season ====
Let's say you want to grant access to a location only in summer:
* <code>is variable_set season:summer</code>

==== Stage of the day ====
Let's say you want to block the access during the night:
* <code>not variable_set stage_of_day:night</code>
while if you want to grant the access only during the night:
* <code>is variable_set stage_of_day:night</code>

==== Steps Countdown ====
Let's say you want to trigger an event after 1234 steps:
* <code>set_variable steps_whatever:1234</code>
<code>steps_</code> followed by your variable <code>whatever</code>.
* <code>is variable_is steps_whatever,equals,0.0</code>: Checking for the results, separate event.

Note: you can replace <code>equals</code> with: <code>less_than</code>, <code>less_or_equal</code>, <code>greater_than</code>, <code>greater_or_equal</code>,  and <code>not_equals</code>.

==== Trading ====
Let's say you want to set up and event for trading monsters. You need 3 events after creating the NPC in map.
* <code>monster1</code> (monster desired by the NPC)
* <code>monster2</code> (monster the NPC wants to trade in exchange)

1st: if the player has the monster
    <property name="act10" value="translated_dialog dialog_npc1"/>
    <property name="act20" value="translated_dialog_choice yes:no,npc_willtrade"/>
    <property name="behav10" value="talk npc_slug"/>
    <property name="cond10" value="is has_monster player,monster1"/>
    <property name="cond20" value="not variable_set npc_hastraded:yes"/>
2nd: if the player hasn't the monster
    <property name="act10" value="translated_dialog dialog_npc1"/>
    <property name="act20" value="translated_dialog dialog_npc_nomonster1"/>
    <property name="behav10" value="talk npc_slug"/>
    <property name="cond10" value="not has_monster player,monster1"/>
    <property name="cond20" value="not variable_set npc_hastraded:yes"/>
3rd: trading part
    <property name="act10" value="translated_dialog dialog_npc_willtrade"/>
    <property name="act20" value="get_player_monster name_variable"/>
    <property name="act30" value="trading name_variable,traded_monster"/>

    <property name="cond10" value="is has_monster player,monster1"/>
    <property name="cond20" value="is variable_set npc_willtrade"/>
    <property name="cond30" value="not variable_set npc_hastraded"/>

==== Get Party Monster ====
Let's say you want to add a tech to a monster (NPC). Eg. the NPC [[Rockitten]] needs to know [[Canine]], but [[Rockitten]] is the 4th monster (equal to 3rd slot).

    <property name="act10" value="add_monster rockitten,20,npc_slug,27,10"/>
    <property name="act20" value="add_monster vivipere,20,npc_slug,27,10"/>
    <property name="act30" value="add_monster budaye,20,npc_slug,27,10"/>
    <property name="act40" value="add_monster rockitten,20,npc_slug,27,10"/>
    <property name="act50" value="add_monster nut,20,npc_slug,27,10"/>
    <property name="act60" value="get_party_monster npc_slug"/>
    <property name="act70" value="add_tech iid_slot_3,canine"/> ---> iid_slot_3 followed by [[Canine]]
    <property name="act80" value="start_battle player,npc_slug"/>

==== Battle Among NPCs (the player watches without interacting) ====
(eg npc_maple vs npc_apple)

    <property name="act10" value="create_npc npc_maple,0,7,stand"/>
    <property name="act20" value="create_npc npc_apple,0,8,stand"/>
    <property name="act30" value="add_monster chloragon,3,npc_maple"/>
    <property name="act40" value="add_monster rockitten,3,npc_apple"/>
    <property name="act50" value="start_battle npc_maple,npc_apple"/>
separate event, multiple endings, if npc_maple wins
    <property name="cond1" value="is variable_set battle_last_winner:npc_maple"/>
separate event, multiple endings, if npc_apple wins
    <property name="cond1" value="not variable_set battle_last_winner:npc_maple"/>
separate event, multiple endings, if no-one wins
    <property name="cond1" value="is variable_set battle_last_result:draw"/>
