  1. Mobs Redo API
  2. =============
  3. Welcome to the world of mobs in minetest and hopefully an easy guide to defining
  4. your own mobs and having them appear in your worlds.
  5. Registering Mobs

  168. 'textures' holds a table list of textures to be used for mob, or you
  169. could use multiple lists inside another table for random

  217. Node Replacement
  218. ----------------
  219. Mobs can look around for specific nodes as they walk and replace them to mimic
  220. eating.
  221. 'replace_what' group of items to replace e.g.
  222. {"farming:wheat_8", "farming:carrot_8"}
  223. or you can use the specific options of what, with and
  224. y offset by using this instead:
  225. {
  226. {"group:grass", "air", 0},
  227. {"default:dirt_with_grass", "default:dirt", -1}
  228. }
  229. 'replace_with' replace with what e.g. "air" or in chickens case "mobs:egg"
  230. 'replace_rate' how random should the replace rate be (typically 10)
  231. 'replace_offset' +/- value to check specific node to replace
  232. 'on_replace(self, pos, oldnode, newnode)' is called when mob is about to
  233. replace a node.
  234. 'self' ObjectRef of mob
  235. 'pos' Position of node to replace
  236. 'oldnode' Current node
  237. 'newnode' What the node will become after replacing
  238. If false is returned, the mob will not replace the node.
  239. By default, replacing sets self.gotten to true and resets the object
  240. properties. (DEPRECATED, use on_replace to make changes).
  241. Custom Definition Functions
  242. ---------------------------
  243. Along with the above mob registry settings we can also use custom functions to
  244. enhance mob functionality and have them do many interesting things:
  245. 'on_die' a function that is called when the mob is killed the
  246. parameters are (self, pos)
  247. 'on_rightclick' its same as in minetest.register_entity()
  248. 'on_blast' is called when an explosion happens near mob when using TNT
  249. functions, parameters are (object, damage) and returns
  250. (do_damage, do_knockback, drops)
  251. 'on_spawn' is a custom function that runs on mob spawn with 'self' as
  252. variable, return true at end of function to run only once.
  253. 'after_activate' is a custom function that runs once mob has been activated
  254. with these paramaters (self, staticdata, def, dtime)
  255. 'on_breed' called when two similar mobs breed, paramaters are
  256. (parent1, parent2) objects, return false to stop child from
  257. being resized and owner/tamed flags and child textures being
  258. applied. Function itself must spawn new child mob.
  259. 'on_grown' is called when a child mob has grown up, only paramater is
  260. (self).
  261. 'do_punch' called when mob is punched with paramaters (self, hitter,
  262. time_from_last_punch, tool_capabilities, direction), return
  263. false to stop punch damage and knockback from taking place.
  264. 'custom_attack' when set this function is called instead of the normal mob
  265. melee attack, parameters are (self, to_attack).
  266. 'on_die' a function that is called when mob is killed (self, pos)
  267. 'do_custom' a custom function that is called every tick while mob is
  268. active and which has access to all of the self.* variables
  269. e.g. ( for health or self.standing_in for node
  270. status), return with 'false' to skip remainder of mob API.
  271. Internal Variables
  272. ------------------
  273. The mob api also has some preset variables and functions that it will remember
  274. for each mob.
  275. '' contains current health of mob (cannot exceed
  276. self.hp_max)
  277. 'self.texture_list' contains list of all mob textures
  278. 'self.child_texture' contains mob child texture when growing up
  279. 'self.base_texture' contains current skin texture which was randomly
  280. selected from textures list
  281. 'self.gotten' this is used for obtaining milk from cow and wool from
  282. sheep
  283. 'self.horny' when animal fed enough it is set to true and animal can
  284. breed with same animal
  285. 'self.hornytimer' background timer that controls breeding functions and
  286. mob childhood timings
  287. 'self.child' used for when breeding animals have child, will use
  288. child_texture and be half size
  289. 'self.owner' string used to set owner of npc mobs, typically used for
  290. dogs
  291. 'self.order' set to "follow" or "stand" so that npc will follow owner
  292. or stand it's ground
  293. 'self.nametag' contains the name of the mob which it can show above
  294. Spawning Mobs in World
  295. ----------------------
  296. mobs:spawn({
  297. name = "mobs_monster:tree_monster",
  298. nodes = {"group:leaves"},
  299. max_light = 7,
  300. })
  301. Spawn functions require the following settings, some of which already have a
  302. default setting and can be omitted:
  303. 'name' is the name of the animal/monster
  304. 'nodes' is a list of nodenames on that the animal/monster can
  305. spawn on top of (defaults to {"group:dirt", "group:stone"}
  306. 'neighbors' is a list of nodenames on that the animal/monster will
  307. spawn beside (default is {"air"})
  308. 'interval' is same as in register_abm() (default is 30)
  309. 'chance' is same as in register_abm() (default is 5000)
  310. 'min_light' is the minimum light level (default is 0)
  311. 'max_light' is the maximum light (default is 15)
  312. 'min_height' is the minimum height a mob can spawn (default: -31000)
  313. 'max_height' is the maximum height a mob can spawn (default is 31000)
  314. 'active_object_count' number of this type of mob to spawn at one time inside
  315. map area (default is 1)
  316. 'day_toggle' true for day spawning, false for night or nil for
  317. anytime
  318. 'on_spawn' is a custom function which runs after mob has spawned
  319. and gives self and pos values.
  320. The older spawn functions are still active and working but have no defaults like
  321. the mobs:spawn, so it is recommended to use the above instead.
  322. mobs:register_spawn(name, nodes, max_light, min_light, chance,
  323. active_object_count, max_height, day_toggle)
  324. mobs:spawn_specfic(name, nodes, neighbors, min_light, max_light, interval,
  325. chance, active_object_count, min_height, max_height, day_toggle, on_spawn)
  326. A simpler way to handle mob spawns has been added with the mobs:spawn(def)
  327. command which uses above names to make settings clearer:
  328. For each mob that spawns with this function is a field in mobs.spawning_mobs.
  329. It tells if the mob should spawn or not. Default is true. So other mods can
  330. only use the API of this mod by disabling the spawning of the default mobs in
  331. this mod.
  332. mobs:spawn_abm_check(pos, node, name)
  333. This global function can be changed to contain additional checks for mobs to
  334. spawn e.g. mobs that spawn only in specific areas and the like. By returning
  335. true the mob will not spawn.
  336. 'pos' holds the position of the spawning mob
  337. 'node' contains the node the mob is spawning on top of
  338. 'name' is the name of the animal/monster
  339. Making Arrows

  343. 'name' is the name of the arrow
  344. 'definition' is a table with the following values:
  345. 'visual' same is in minetest.register_entity()
  346. 'visual_size' same is in minetest.register_entity()
  347. 'textures' same is in minetest.register_entity()
  348. 'velocity' the velocity of the arrow
  349. 'drop' if set to true any arrows hitting a node will drop as item

  351. this function should hurt the player, the parameters are
  352. (self, player)
  353. 'hit_mob' a function that is called when the arrow hits a mob;
  354. this function should hurt the mob, the parameters are
  355. (self, player)
  356. 'hit_object' a function that is called when the arrow hits an object;
  357. this function parameters are (self, player)
  358. 'hit_node' a function that is called when the arrow hits a node, the
  359. parameters are (self, pos, node)
  360. 'tail' when set to 1 adds a trail or tail to mob arrows
  361. 'tail_texture' texture string used for above effect
  362. 'tail_size' has size for above texture (defaults to between 5 and 10)
  363. 'expire' contains float value for how long tail appears for

  367. 'rotate' integer value in degrees to rotate arrow
  368. 'on_step' is a custom function when arrow is active, nil for
  369. default.
  370. 'on_punch' is a custom function when arrow is punched, nil by default
  371. 'collisionbox' is hitbox table for arrow, {0,0,0,0,0,0} by default.
  372. Spawn Eggs
  373. ----------
  374. mobs:register_egg(name, description, background, addegg, no_creative)
  375. This function registers a spawn egg which can be used to properly spawn in a mob.
  376. Animals are spawned as tamed unless sneak/shift is held while spawning.
  377. 'name' this is the name of your new mob to spawn e.g. "mob:sheep"

  384. Explosion Function
  385. ------------------

  388. 'self' mob entity
  389. 'pos' centre position of explosion
  390. 'radius' radius of explosion (typically set to 3)
  391. This function generates an explosion which removes nodes in a specific radius
  392. and damages any entity caught inside the blast radius. Protection will limit
  393. node destruction but not entity damage.
  394. Capturing Mobs
  395. --------------
  396. mobs:capture_mob(self, clicker, chance_hand, chance_net, chance_lasso,
  397. force_take, replacewith)
  398. This function is generally called inside the on_rightclick section of the mob
  399. api code, it provides a chance of capturing the mob by hand, using the net or
  400. lasso items, and can also have the player take the mob by force if tamed and
