-- Advanced NPC spawner by Zorman2000 -- The advanced spawner will contain functionality to spawn NPC correctly on -- custom places, as well as in mg_villages building. -- This works by using a special node to spawn NPCs on either a custom building or -- on mg_villages building. -- mg_villages functionality: -- The spawn node for mg_villages will be the mg_villages:plotmarker. -- Based on this node, the following things will be performed -- - Scan the current building, check if it is of type: -- - House -- - Farm -- - Hut -- - NOTE: All other types are unsupported as-of now -- - If it's from any of the above types, the spawner will proceed to scan the -- the building and find out: -- - Number and positions of beds -- - Number and positions of benches -- - Number and positions of chests -- - Position of furnaces -- - Position of doors -- - NOTE: Scanning will be implemented for first floors only in the first -- version. It's expected to also include upper floors later. -- - After that, it will store these information in the node's metadata. -- - The spawner will analyze the information and will spawn (# of beds/2) or 1 -- NPC in that house. The NPCs will be spawned in intervals, for which the node -- will create node timers for each NPC. -- - When a NPC is spawned: -- - The NPC will be given a schedule -- - If in a farm, the NPC will have a "farmer schedule" with a 40% chance -- - If in a house or hut, the NPC will have either a miner, woodcutter, cooker -- or simple schedule with an equal chance each -- - The NPC will be assigned a unique bed -- - The NPC will know the location of one chest, one bench and one furnace -- - A life timer for the NPC will be created (albeit a long one). Once the NPC's -- timer is invoked, the NPC will be de-spawned (dies). The spawner should keep -- track of these. -- - If a NPC has died, the spawner will choose with 50% chance to spawn a new NPC. -- -- This is the basic functionality expected for the spawner in version 1. Other things -- such as scanning upper floors, spawning families of NPCs and creating relationships -- among them, etc. will be for other versions. -- Public API npc.spawner = {} -- Private API local spawner = {} -- This is the official list of support building types -- from the mg_villages mod npc.spawner.mg_villages_supported_building_types = { "house", "farm_full", "farm_tiny", "hut", "lumberjack" } npc.spawner.replace_activated = true npc.spawner.replacement_interval = 60 npc.spawner.spawn_delay = 10 npc.spawner.spawn_data = { status = { dead = 0, alive = 1 }, age = { adult = "adult", child = "child" } } -- Array of nodes that serve as plotmarker of a plot, and therefore -- as auto-spawners spawner.plotmarker_nodes = {} -- Array of items that are used to spawn NPCs spawner.spawn_eggs = {} --------------------------------------------------------------------------------------- -- Scanning functions --------------------------------------------------------------------------------------- -- This function scans a 3D area that encloses a building and tries to identify: -- - Entrance door -- - Beds -- - Storage nodes (chests, etc.) -- - Furnace nodes -- - Sittable nodes -- It will return a table with all information gathered -- Playername should be provided if manual spawning function npc.spawner.scan_area_for_spawn(start_pos, end_pos, player_name) local result = { building_type = "", building_plot_info = {}, building_entrance = {}, building_usable_nodes = {}, building_npcs = {}, building_npc_stats = {} } -- Set building_type result.building_type = "custom" -- Get min pos and max pos local minp, maxp = vector.sort(start_pos, end_pos) -- Set plot info result.building_plot_info = { -- TODO: Check this and see if it is accurate! xsize = maxp.x - minp.x, ysize = maxp.y - minp.y, zsize = maxp.z - minp.z, start_pos = start_pos, end_pos = end_pos } -- Scan building nodes -- Scan building for nodes local usable_nodes = npc.places.scan_area_for_usable_nodes(start_pos, end_pos) -- Get all doors local doors = usable_nodes.openable_type -- Find entrance node - this is very tricky when no outside position -- is given.
