Npc

Easy to create Non-Player-Character (NPC) for your REDM resource.

Example

------------------------------------------------------------------------------
-- Step 1: Get API
------------------------------------------------------------------------------

---@type NssLibsNpcApi
local npc_api = exports.nss_libs:getNpcApi(GetCurrentResourceName())

------------------------------------------------------------------------------
-- Step 2: Create NPC object
------------------------------------------------------------------------------

local model_name = 'S_M_M_NBXRIVERBOATDEALERS_01'
local outfit = 0 -- nil/false = random outfit
local x = 0
local y = 0
local z = 0
local heading = 180

---@type NssLibsNpcEntityApi
local npc = npc_api.create(model_name, x, y, z, heading, outfit)

------------------------------------------------------------------------------
-- Step 3: Configure NPC object
------------------------------------------------------------------------------

npc.setScale(1)
   .setScenario('WORLD_HUMAN_WRITE_NOTEBOOK')
   .setWeapon('weapon_shotgun_semiauto')
   .addAnimation(
        'amb_camp@prop_camp_butcher@resting@rabbit@male_a@idle_a',
        'idle_c',
        10000, -- delay/duration until next animation
        true, -- looping
        1, -- times to play
        npc.ANIMATE_ONLY_UPPER_BODY) -- animate only upper body
   .addAnimation(
        'amb_camp@prop_camp_butcher@resting@rabbit@male_a@idle_a',
        'idle_b',
        3000, -- delay/duration until next animation
        false, -- no looping
        3, -- play 3 times with a delay of 3000ms
        npc.ANIMATE_FULL_BODY) -- animate full body
   .addTimeWindow(8, 0, 12, 0) -- visible from 8:00 to 12:00 in-game-time
   .addTimeWindow(14, 0, 20, 0) -- visible from 14:00 to 20:00 in-game-time

------------------------------------------------------------------------------
-- Step 4: Show NPC
------------------------------------------------------------------------------

-- With performance mode to prevent too much entities
local spawn_radius = 20 -- in meters
npc.startRangeCheck(spawn_radius)

-- Without performance mode
npc.show()
