1. Подготовте файлы:
configs\creatures\game_relations.ltx
configs\creatures\spawn_sections_general.ltx
configs\gameplay\character_desc_general.xml
con figs\gameplay\npc_profile.xml
configs\misc\death_items_by_communities.ltx
configs\misc\dialog_manager.ltx
configs\text\rus\st_dialog_mana ger.xml
scripts\death_manager.script

2. Создаем группировку.

а) В файле game_relations вписываем:

в конец строки "communities" дописываем название группировки, например "ветер" и добавляем порядковый номер: 11

Выглядит это вот так:
communities = actor, 0, bandit, 1, dolg, 2, ecolog, 3, freedom, 4, killer, 5, army, 6, monolith, 7, monster, 8, stalker, 9, zombied, 10, veter, 11

ниже в таблицу communities_relations добавляем (по горизонтали и вертикали) veter и прописываем отношение к другим группировкам (-5000 - полный враг, 0 - нейтрал, 5000 - друг до конца жизни)

Выглядит это так:
[communities_relations]
; |actor|bandit| dolg|ecolog|freedom|killer| army|monolith|monster|stalker| zombied|veter|
;==========================================================================================================
actor = 0, 0, 0, 0, 0, -1000, 0, -5000, -5000, 0, -5000, 0
bandit = 0, 5000,-5000, 0, -5000, 0, -5000, -5000, -5000, -1000, -5000, -1000
dolg = 0, -5000, 5000, 0, -5000, 0, 0, -5000, -5000, 0, -5000, 0
ecolog = 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
freedom = 0, -5000,-5000, 0, 5000, 0, 0, -5000, -5000, 0, -5000, 0
killer = -1000, 0, 0, 0, 0, 1000, -5000, -5000, -5000, 0, -5000, 0
army = 0, -5000, 0, 0, 0, -5000, 1000, -5000, -5000, 0, -5000, 0
monolith = -5000, -5000,-5000, 0, -5000, -5000, -5000, 1000, -5000, -5000, 1000, -1000
monster = -5000, -5000,-5000, 0, -5000, -5000, -5000, -5000, 0, -5000, -5000, -5000
stalker = 0, -1000, 0, 0, 0, 0, 0, -5000, -5000, 0, -5000, 0
zombied = -5000, -5000,-5000, 0, -5000, -5000, -5000, 1000, -5000, -5000, 1000, 0
veter = 0 , -1000, 0 , 0, 0, 0, 0, -1000, -5000, 0, 0, 5000

ниже в конец строки communities_sympathy добавляем:
veter = 0.0

Б) В конец файла death_items_by_communities вписываем:
[veter]:stalker

В) В файле death_manager.script в конец строки local community_list дописываем "veter"
Выглядит это так:
local community_list = { "stalker", "dolg", "freedom", "bandit", "army", "zombied", "ecolog", "killer", "monolith", "veter"}

3. Создание НПС группировки

А) В файле spawn_sections_general создаем строки:

;***** sim veter *****
[sim_default_veter_0]:stalker
$spawn = "respawn\sim_default_veter_0"
character_profile = sim_default_veter_0
spec_rank = novice
community = veter

[sim_default_veter_1]:stalker
$spawn = "respawn\sim_default_veter_1"
character_profile = sim_default_veter_1
spec_rank = regular
community = veter

[sim_default_veter_2]:stalker
$spawn = "respawn\sim_default_veter_2"
character_profile = sim_default_veter_2
spec_rank = experienced
community = veter

[sim_default_veter_3]:stalker
$spawn = "respawn\sim_default_veter_3"
character_profile = sim_default_veter_3
spec_rank = veteran
community = veter

[sim_default_veter_4]:stalker
$spawn = "respawn\sim_default_veter_4"
character_profile = sim_default_veter_4
spec_rank = master
community = veter

Б) В файле character_desc_general создаем такую запись:

<!-- -->
<!-- ` VETER -->
<!-- -->

<!-- veter novice -->

Меняйте все по усмотрению!

В) В файле npc_profile создаем

<!-- sim veter -->
<character id="sim_default_veter_0">
<class>sim_default_veter_0</class>
</character>
<character id="sim_default_veter_1">
<class>sim_default_veter_1</class>
</character>
<character id="sim_default_veter_2">
<class>sim_default_veter_2</class>
</character>
<character id="sim_default_veter_3">
<class>sim_default_veter_3</class>
</character>
<character id="sim_default_veter_4">
<class>sim_default_veter_4</class>
</character>

4. Создаем самый простой диалог (чтобы при нажатии клавишы "говорить" игра не вылетала)

А) В dialog_manager.ltx в столбце LIST находим записи dm_hello и после dm_hello_17 добавляем dm_hello_18
Вот так:
dm_hello_0
dm_hello_1
dm_hello_2
dm_hello_3
dm_hello_4
dm_hello_5
dm_hello_6
dm_hello_7
dm_hello_8
dm_hello_9
dm_hello_10
d m_hello_11
dm_hello_12
dm_hello_13
dm_hello_14
dm_hello_15
dm_hello_16
dm_hello_17
dm_hello_18
dm_hello_19

Б) В конец этого же файла строчку:
[dm_hello_18]
category = hello
npc_community = veter
level = all

В) В файле st_dialog_manager.xml создаем:
<string id="dm_hello_18">
<text>О, здоров, ну что, как?</text>
</string>

ГОТОВО! Можно ставить НПС на карту и играть!
