Mobs Redo API
=============
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.
Quick Note
----------
Since the mobs redo api checks for nodes around the mob to function, it relies on a
default node incase anything goes wrong, so in the default game this is default:dirt
but for any custom game please make sure the following line is registered with your
preferred dirt node of choice:
minetest.register_alias("mapgen_dirt", "mymod:my_dirt_node")
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

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_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. (DEPRECATED, use on_replace to make changes).
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_rightclick' its same as in minetest.register_entity()
'on_blast' is called when an explosion happens near mob when using TNT
functions, parameters are (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) and if true
is returned normal attack function continued.
'on_die' a function that is called when mob is killed (self, pos), also
has access to self.cause_of_death table.
'on_flop' function called when flying or swimmimng mob is no longer in
air/water, (self) paramater and return true to skip the built
in api flop feature.
'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)

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
'self.pause_timer' used to stop mob thinking when punched so that knockback
can take effect.
'self.disable_falling' currently used on spider mob when climbing walls, stops
the mob from experiencing gravity when true.
'self.state' Current mob state.
"stand": no movement (except turning around)
"walk": walk or move around aimlessly

'self.looking_at' Node name in front of mob.
'self.looking_above'Node name in front/above mob.
'self.facing_fence' True if mob facing node containing "wall", "fence", "gate"
in it's name.
Adding Mobs in World
--------------------
mobs:add_mob(pos, {
name = "mobs_animal:chicken",
child = true,
owner = "singleplayer",
nametag = "Bessy",
ignore_count = true -- ignores mob count per map area
})
Returns false if mob could not be added, returns mob object if spawned ok.
Removing Mob from World
-----------------------
mobs:remove(self, decrease)
Removes mob 'self' from the world and if 'decrease' is true then the mob counter
will also be decreased by one.
Spawning Mobs in World
----------------------
mobs:spawn({
name = "mobs_monster:tree_monster",
nodes = {"group:leaves"},
max_light = 7,
})
Spawn functions require the following settings, some of which already have a
default setting and can be omitted:
'name' is the name of the animal/monster
'nodes' is a list of nodenames on that the animal/monster can
spawn on top of (defaults to {"group:dirt", "group:stone"}
'neighbors' is a list of nodenames on that the animal/monster will
spawn beside (default is {"air"})
'interval' is same as in register_abm() (default is 30)
'chance' is same as in register_abm() (default is 5000)
'min_light' is the minimum light level (default is 0)
'max_light' is the maximum light (default is 15)
'min_height' is the minimum height a mob can spawn (default: -31000)
'max_height' is the maximum height a mob can spawn (default is 31000)
'active_object_count' number of this type of mob to spawn at one time inside
map area (default is 1)
'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.
'on_map_load' when true mobs will have a chance of spawning only
when new areas of map are loaded, interval will not be
used.
The older spawn functions are still active and working but have no defaults like
the mobs:spawn, so it is recommended to use the above instead.
mobs:register_spawn(name, nodes, max_light, min_light, chance,
active_object_count, max_height, day_toggle)
mobs:spawn_specific(name, nodes, neighbors, min_light, max_light, interval,
chance, active_object_count, min_height, max_height, day_toggle, on_spawn)
A simpler way to handle mob spawns has been added with the mobs:spawn(def)
command which uses above names to make settings clearer:
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

Spawn Eggs
----------
mobs:register_egg(name, description, background, addegg, no_creative)

'self.driver_attach_at' position offset for attaching player to mob
'self.driver_eye_offset' position offset for attached player view
'self.driver_scale' sets driver scale for mobs larger than {x=1, y=1}
mobs:line_of_sight(self, pos1, pos2, stepsize) [DEPRECATED]
This function is for use within the mobs definition for special use cases and
returns true if a mob can see the player or victim.
...'self' mob information
'pos1' position of mob
'pos2' position of vistim or player
'stepsize' usually set to 1
Use this instead:
mob_class:line_of_sight(pos1, pos2, stepsize)
mobs:can_spawn(pos, name)
This function checks the surrounding area at [pos] to see if there is enough empty
space to spawn mob [name], if so then a new position is returned for use,
otherwise nil is returned.
mobs:is_node_dangerous(mob_object, nodename)
This function returns true if the node name given is harmful to the mob (mob_object),
it is mainly used when a mob is near a node it has to avoid.
Looting Level
-------------
If a tool is used with 'looting_level' defined under tool_capabilities then mobs can drop
extra items per level up to a maximum of 3 levels. 'looting_level' can also be read from
the tools own meta to override the default.
External Settings for "minetest.conf"
------------------------------------
'mob_node_timer_interval' How often mobs get nodes around them (0.25 is default)
for every 1/4 second.
'mob_main_timer_interval' How often mobs run main functions (1.0 is default) for
every one second.
'enable_damage' if true monsters will attack players (default is true)
'only_peaceful_mobs' if true only animals will spawn in game (default is
false)
'mobs_attack_creatura' When True mobs redo mobs will attack Creatura mod mobs.
'mobs_disable_blood' if false blood effects appear when mob is hit (default
is false)
'mob_hit_effect' False by default, when True and mobs are hit then
damage_texture_modifier is used to highlight mob.
'mobs_spawn_protected' if set to false then mobs will not spawn in protected
areas (default is true)
'mobs_spawn_monster_protected' if set to false then monsters will not spawn in
protected areas (default is true)
'remove_far_mobs' if true then untamed mobs that are outside players
visual range will be removed (default is true)
'mobname' can change specific mob chance rate (0 to disable) and
spawn number e.g. mobs_animal:cow = 1000,5
'mob_difficulty' sets difficulty level (health and hit damage
multiplied by this number), defaults to 1.0.
'mob_chance_multiplier' multiplies chance of all mobs spawning and can be set
to 0.5 to have mobs spawn more or 2.0 to spawn less.
e.g. 1 in 7000 * 0.5 = 1 in 3500 so better odds of
spawning.
'mobs_spawn' if false then mobs no longer spawn without spawner or
spawn egg.
'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.
'mob_nospawn_range' Minimum range a mob can spawn near player (def: 12)
'mob_active_limit' Number of active mobs in game, 0 for unlimited
'mob_area_spawn' When true will check surrounding area the size of the
mob for obstructions before spawning, otherwise it
defaults to checking the height of the mob only.
'mob_smooth_rotate' Enables smooth rotation when mobs turn by default.
'mob_height_fix' Enabled by default, increases smaller mob heights so they wont
glitch through certain nodes.
'mob_pathfinding_enable' Enable pathfinding.
'mob_pathfinder_enable' Use pathfinder mod if available.
'mob_pathfinding_stuck_timeout' How long before stuck mobs start searching. (default 3.0)
'mob_pathfinding_stuck_path_timeout' How long will mob follow path before giving up. (default 5.0)
'mob_pathfinding_algorithm' Which pathfinding algorithm to use Dijkstra (default), A*_noprefetch (AStar_noprefetch) or A* (AStar)
(A* names differ cause Minetest doesn´t allow "*" in settings)
'mob_pathfinding_searchdistance' max search distance from search positions (default 16)
'mob_pathfinding_max_jump' max jump height for pathfinding (default 4)
'mob_pathfinding_max_drop' max drop height for pathfinding (default 6)
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 11000
mobs_monster:sand_monster 100
...you can also change how many of a certain mob appear in an active mapblock by
adding a comma and then a new value e.g.
mobs_animal:cow = 8000,4 <-- 4 cows per mapblock at 8000 spawn chance
mobs_monster:dirt_monster = ,20 <-- 20 dirt monsters per mapblock
