Welcome to the world of mobs in minetest and hopefully an easy guide to defining
your own mobs and having them appear in your worlds.
Registering Mobs
----------------
To register a mob and have it ready for use requires the following function:
mobs:register_mob(name, definition)
The 'name' of a mob usually starts with the mod name it's running from followed
by it's own name e.g.
"mobs_monster:sand_monster" or "mymod:totally_awesome_beast"
... and the 'definition' is a table which holds all of the settings and
functions needed for the mob to work properly which contains the following:
'nametag' contains the name which is shown above mob.

kill monsters.
'hp_min' has the minimum health value the mob can spawn with.

older mobs.
Node Replacement
----------------
Mobs can look around for specific nodes as they walk and replace them to mimic
eating.
'replace_what' group of items to replace e.g.
{"farming:wheat_8", "farming:carrot_8"}
or you can use the specific options of what, with and
y offset by using this instead:
{
{"group:grass", "air", 0},
{"default:dirt_with_grass", "default:dirt", -1}
}
'replace_with' replace with what e.g. "air" or in chickens case "mobs:egg"
'replace_rate' how random should the replace rate be (typically 10)
'replace_offset' +/- value to check specific node to replace
'on_replace(self, pos, oldnode, newnode)' is called when mob is about to
replace a node.
'self' ObjectRef of mob
'pos' Position of node to replace
'oldnode' Current node
'newnode' What the node will become after replacing
If false is returned, the mob will not replace the node.
By default, replacing sets self.gotten to true and resets the object
properties.
Custom Definition Functions
---------------------------
Along with the above mob registry settings we can also use custom functions to
enhance mob functionality and have them do many interesting things:
'on_die' a function that is called when the mob is killed the
parameters are (self, pos)
'on_rightclick' its same as in minetest.register_entity()
'on_blast' is called when an explosion happens near mob when using TNT
functions, parameters are (object, damage) and returns
(do_damage, do_knockback, drops)
'on_spawn' is a custom function that runs on mob spawn with 'self' as
variable, return true at end of function to run only once.
'after_activate' is a custom function that runs once mob has been activated
with these paramaters (self, staticdata, def, dtime)
'on_breed' called when two similar mobs breed, paramaters are
(parent1, parent2) objects, return false to stop child from
being resized and owner/tamed flags and child textures being
applied. Function itself must spawn new child mob.
'on_grown' is called when a child mob has grown up, only paramater is
(self).
'do_punch' called when mob is punched with paramaters (self, hitter,
time_from_last_punch, tool_capabilities, direction), return
false to stop punch damage and knockback from taking place.
'custom_attack' when set this function is called instead of the normal mob
melee attack, parameters are (self, to_attack).
'on_die' a function that is called when mob is killed
'do_custom' a custom function that is called every tick while mob is
active and which has access to all of the self.* variables
e.g. (self.health for health or self.standing_in for node
status), return with 'false' to skip remainder of mob API.
Internal Variables
------------------
The mob api also has some preset variables and functions that it will remember
for each mob.
'self.health' contains current health of mob (cannot exceed
self.hp_max)
'self.texture_list' contains list of all mob textures
'self.child_texture' contains mob child texture when growing up
'self.base_texture' contains current skin texture which was randomly
selected from textures list
'self.gotten' this is used for obtaining milk from cow and wool from
sheep
'self.horny' when animal fed enough it is set to true and animal can
breed with same animal
'self.hornytimer' background timer that controls breeding functions and
mob childhood timings
'self.child' used for when breeding animals have child, will use
child_texture and be half size
'self.owner' string used to set owner of npc mobs, typically used for
dogs
'self.order' set to "follow" or "stand" so that npc will follow owner
or stand it's ground
'self.nametag' contains the name of the mob which it can show above
Spawning Mobs in World
----------------------
mobs:register_spawn(name, nodes, max_light, min_light, chance,
active_object_count, max_height, day_toggle)
mobs:spawn_specfic(name, nodes, neighbors, min_light, max_light, interval,
chance, active_object_count, min_height, max_height, day_toggle, on_spawn)
These functions register a spawn algorithm for the mob. Without this function
the call the mobs won't spawn.
'name' is the name of the animal/monster
'nodes' is a list of nodenames on that the animal/monster can
spawn on top of
'neighbors' is a list of nodenames on that the animal/monster will
spawn beside (default is {"air"} for
mobs:register_spawn)
'max_light' is the maximum of light
'min_light' is the minimum of light
'interval' is same as in register_abm() (default is 30 for
mobs:register_spawn)
'chance' is same as in register_abm()
'active_object_count' number of this type of mob to spawn at one time inside
map area
'min_height' is the minimum height the mob can spawn
'max_height' is the maximum height the mob can spawn
'day_toggle' true for day spawning, false for night or nil for
anytime
'on_spawn' is a custom function which runs after mob has spawned
and gives self and pos values.
A simpler way to handle mob spawns has been added with the mobs:spawn(def)
command which uses above names to make settings clearer:
mobs:spawn({name = "mobs_monster:tree_monster",
nodes = {"group:leaves"},
max_light = 7,
})
For each mob that spawns with this function is a field in mobs.spawning_mobs.
It tells if the mob should spawn or not. Default is true. So other mods can
only use the API of this mod by disabling the spawning of the default mobs in
this mod.
Making Arrows
-------------
mobs:register_arrow(name, definition)
This function registers a arrow for mobs with the attack type shoot.
'name' is the name of the arrow
'definition' is a table with the following values:
'visual' same is in minetest.register_entity()
'visual_size' same is in minetest.register_entity()
'textures' same is in minetest.register_entity()
'velocity' the velocity of the arrow
'drop' if set to true any arrows hitting a node will drop as item
'hit_player' a function that is called when the arrow hits a player;
this function should hurt the player, the parameters are
(self, player)
'hit_mob' a function that is called when the arrow hits a mob;
this function should hurt the mob, the parameters are
(self, player)
'hit_node' a function that is called when the arrow hits a node, the
parameters are (self, pos, node)
'tail' when set to 1 adds a trail or tail to mob arrows
'tail_texture' texture string used for above effect
'tail_size' has size for above texture (defaults to between 5 and 10)
'expire' contains float value for how long tail appears for
(defaults to 0.25)
'glow' has value for how brightly tail glows 1 to 10 (default is
0 for no glow)
'rotate' integer value in degrees to rotate arrow
'on_step' is a custom function when arrow is active, nil for
default.
Spawn Eggs
----------
mobs:register_egg(name, description, background, addegg, no_creative)
This function registers a spawn egg which can be used by admin to properly spawn in a mob.
'name' this is the name of your new mob to spawn e.g. "mob:sheep"
'description' the name of the new egg you are creating e.g. "Spawn Sheep"
'background' the texture displayed for the egg in inventory
'addegg' would you like an egg image in front of your texture (1 = yes,
0 = no)
'no_creative' when set to true this stops spawn egg appearing in creative
mode for destructive mobs like Dungeon Masters.
Explosion Function
------------------
mobs:explosion(pos, radius) -- DEPRECATED!!! use mobs:boom() instead
mobs:boom(self, pos, radius)
'self' mob entity
'pos' centre position of explosion
'radius' radius of explosion (typically set to 3)

disable
'force_take' take mob by force, even if tamed (true or false)
'replacewith' once captured replace mob with this item instead (overrides
new mob eggs with saved information)
Feeding and Taming/Breeding
---------------------------
mobs:feed_tame(self, clicker, feed_count, breed, tame)
