Mobs Redo: MineClone 2 Edition
API documentation
==============================

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.
   'type'          holds the type of mob that inhabits your world e.g.
      "animal"     usually docile and walking around.
      "monster"    attacks player or npc on sight.
      "npc"        walk around and will defend themselves if hit first, they
                   kill monsters.
   'hp_min'        the minimum health value the mob can spawn with.
   'hp_max'        the maximum health value the mob can spawn with.
   'breath_max'    The maximum breath value the mob can spawn with and can have.
                   If -1 (default), mob does not take drowning damage.
   'breathes_in_water' If true, mob loses breath when not in water. Otherwise,
                   mob loses breath when inside a node with `drowning` attribute
                   set (default: false).
   'armor'         entity armor groups (see lua_api.txt). If table, a list of
                   armor groups like for entities. If number, set value of
                   'fleshy' armor group only.
                   Note: The 'immortal=1' armor group will automatically be added
                   since this mod handles health and damage manually.
                   Default: 100 (mob will take full dmg from 'fleshy' hits)
   'passive'       when true allows animals to defend themselves when hit,
                   otherwise they amble onwards.
   'walk_velocity' is the speed that your mob can walk around.
   'run_velocity'  is the speed your mob can run with, usually when attacking.

   'fly_in'        holds the node name or a table of node names in which the
                   mob flies (or swims) around in. The special name
                   '__airlike' stands for all nodes with 'walkable=false'
                   that are not liquids
   'runaway'       if true causes animals to turn and run away when hit.
   'view_range'    how many nodes in distance the mob can see a player.

      'spawn_small_alternative': name of a smaller mob to use as replacement if
                                 spawning fails due to space requirements
      'glow' same as in entity definition
      'child' if true, spawn mob as child
      'shoot_arrow(self, pos, dir)' function that is called when mob wants to shoot an arrow.
                                    You can spawn your own arrow here. pos is mob position,
                                    dir is mob's aiming direction
      'sounds_child' same as sounds, but for childs. If not defined, childs will use same

      'fire_damage_resistant' If true the mob will not take damage when burning
      'ignited_by_sunlight' If true the mod will burn at daytime. (Takes sunlight_damage per second)



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. Also called
          when not actually replacing due to mobs_griefing setting being false.
      '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). Return true to skip the builtin
                    death animation and death effects
   '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 (self, pos)
   '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.breath'        contains current breath of mob, if mob takes drowning
                        damage at all (cannot exceed self.breath_max). Breath
                        decreases by 1 each second while in a node with drowning
                        damage and increases by 1 each second otherwise.
   '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 to track whether some special item has been
                        gotten from the mob, for example, wool from sheep.
                        Initialized as false, and the mob must set this value
                        manually.
   '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

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.


mobs:spawn_abm_check(pos, node, name)

This global function can be changed to contain additional checks for mobs to
spawn e.g. mobs that spawn only in specific areas and the like.  By returning
true the mob will not spawn.

    'pos'    holds the position of the spawning mob
    'node'   contains the node the mob is spawning on top of
    'name'   is the name of the animal/monster


MineClone 2 extensions
----------------------

mobs:spawn_child(pos, mob_type)

This function spawns a mob as a child. The parameter mob_type is the
entitystring of the new mob.
This function returns the mob on success and nil otherwise.

mobs:death_effect(pos, collisionbox)

                      (self, mob)
       'hit_object'   a function that is called when the arrow hits an object
                      that is neither a player nor a mob. this function should
                      hurt the object, the parameters are (self, object)
       '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)

                      (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

                 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:boom(self, pos, radius)
   'self' mob entity
   'pos' centre position of explosion
   'radius' radius of explosion (typically set to 3)

This function generates an explosion which removes nodes in a specific radius
and damages any entity caught inside the blast radius.  Protection will limit
node destruction but not entity damage.



Feeding and Taming/Breeding
---------------------------

mobs:feed_tame(self, clicker, feed_count, breed, tame)

External Settings for "minetest.conf"
------------------------------------

   'enable_damage'          if true monsters will attack players (default is true)
   'only_peaceful_mobs'     if true only animals will spawn in game (default is

   'mobs_drop_items'        when false mobs no longer drop items when they die.
   'mobs_griefing'          when false mobs cannot break blocks when using either
                            pathfinding level 2, replace functions or mobs:boom
                            function.

Players can override the spawn chance for each mob registered by adding a line
to their minetest.conf file with a new value, the lower the value the more each
mob will spawn e.g.

mobs_animal:sheep_chance 11000
mobs_monster:sand_monster_chance 100
