MOB API Mobs Redo API
=============
The mob api is a function that can be called on by other mods to add new animals or monsters into minetest. 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.
minetest.conf settings*
'enable_damage' if true monsters will attack players (default is true) Registering Mobs
'only_peaceful_mobs' if true only animals will spawn in game (default is false) ----------------
'mobs_disable_blood' if false blood effects appear when mob is hit (default is false)
'mobs_spawn_protected' if set to false then mobs will not spawn in protected areas (default is true) To register a mob and have it ready for use requires the following function:
'remove_far_mobs' if true then mobs that are outside players visual range will be removed (default is false)
'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_show_health' if false then punching mob will not show health status (true by default)
'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:register_mob(name, definition) mobs:register_mob(name, definition)
This functions registers a new mob as a Minetest entity. The 'name' of a mob usually starts with the mod name it's running from followed
by it's own name e.g.
'name' is the name of the mob (e.g. "mobs:dirt_monster") "mobs_monster:sand_monster" or "mymod:totally_awesome_beast"
definition is a table with the following fields
'type' the type of the mob ("monster", "animal" or "npc") where monsters attack players and npc's, animals and npc's tend to wander around and can attack when hit 1st. ... and the 'definition' is a table which holds all of the settings and
'passive' will mob defend itself, set to false to attack functions needed for the mob to work properly which contains the following:
'docile_by_day' when true, mob will not attack during daylight hours unless provoked
'attacks_monsters' usually for npc's to attack monsters in area 'nametag' contains the name which is shown above mob.
'group_attack' true to defend same kind of mobs from attack in area 'type' holds the type of mob that inhabits your world e.g.

'attack_animals' true for monster to attack animals as well as player and npc's "monster" attacks player or npc on sight.
'specific_attack' has a table of entity names that monsters can attack {"player", "mobs_animal:chicken"} "npc" walk around and will defend themselves if hit first, they
'hp_min' minimum health kill monsters.
'hp_max' maximum health (mob health is randomly selected between both) 'hp_min' has the minimum health value the mob can spawn with.
'nametag' string containing name of mob to display above entity 'hp_max' has the maximum health value the mob can spawn with.
'physical' same is in minetest.register_entity() 'armor' holds strength of mob, 100 is normal, lower is more powerful
'collisionbox' same is in minetest.register_entity() and needs more hits and better weapons to kill.
'selectionbox' same is in minetest.register_entity() 'passive' when true allows animals to defend themselves when hit,
'visual' same is in minetest.register_entity() otherwise they amble onwards.
'visual_size' same is in minetest.register_entity() 'walk_velocity' is the speed that your mob can walk around.
'textures' same is in minetest.register_entity() 'run_velocity' is the speed your mob can run with, usually when attacking.
although you can add multiple lines for random textures {{"texture1.png"},{"texture2.png"}}, 'walk_chance' has a 0-100 chance value your mob will walk from standing,
'gotten_texture' alt. texture for when self.gotten value is set to true (used for shearing sheep) set to 0 for jumping mobs only.

'makes_footstep_sound' same is in minetest.register_entity() 'fly' when true allows your mob to fly around instead of walking.
'follow' item when held will cause mob to follow player, can be single string "default:apple" or table {"default:apple", "default:diamond"}. These are also items that are used to feed and tame mob. 'fly_in' holds the node name that the mob flies (or swims) around
'view_range' the range in which the mob will follow or attack player in e.g. "air" or "default:water_source".

'immune_to' table holding special tool/item names and damage the incur e.g. 'water_damage' holds the damage per second infliced to mobs when standing in
{"default:sword_wood", 0}, {"default:gold_lump", -10} immune to sword, gold lump heals water.
'blood_amount' number of droplets that appear when hit 'lava_damage' holds the damage per second inflicted to mobs when standing
'blood_texture' texture of blood droplets (default: "mobs_blood.png") in lava or fire.

'min' the minimum number of items 'floats' when set to 1 mob will float in water, 0 has them sink.
'max' the maximum number of items 'follow' mobs follow player when holding any of the items which appear
'armor' this integer holds armor strength with 100 being normal, with lower numbers hardening the armor and higher numbers making it weaker (weird I know but compatible with simple mobs) on this table, the same items can be fed to a mob to tame or
'drawtype' "front" or "side" (DEPRECATED, replaced with below) breed e.g. {"farming:wheat", "default:apple"}
'rotate' set mob rotation, 0=front, 90=side, 180=back, 270=other side
'water_damage' the damage per second if the mob is in water 'reach' is how far the mob can attack player when standing

Node Replacement
----------------
Mobs can look for specific nodes as they walk and replace them to mimic eating. Mobs can look around for specific nodes as they walk and replace them to mimic
eating.
'replace_what' group if items to replace e.g. {"farming:wheat_8", "farming:carrot_8"} '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_with' replace with what e.g. "air" or in chickens case "mobs:egg"

'on_replace(self, pos, oldnode, newnode)' gets called when mob is about to replace a node
self: ObjectRef of mob 'on_replace(self, pos, oldnode, newnode)' is called when mob is about to
pos: Position of node to replace replace a node.
oldnode: Current node 'self' ObjectRef of mob
newnode: What the node will become after replacing '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. If false is returned, the mob will not replace the node.
By default, replacing sets self.gotten to true and resets the object properties. By default, replacing sets self.gotten to true and resets the object
properties.
The 'replace_what' has been updated to use tables for what, with and y_offset e.g.
replace_what = { {"group:grass", "air", 0}, {"default:dirt_with_grass", "default:dirt", -1} }
Mob animation comes in three parts, start_frame, end_frame and frame_speed which
can be added to the mob definition under pre-defined mob animation names like:
'animation' a table with the animation ranges and speed of the model
'stand_start', 'stand_end', 'stand_speed' when mob stands still
'walk_start', 'walk_end', 'walk_speed' when mob walks
'run_start', 'run_end', 'run_speed' when mob runs

'die_start', 'die_end', 'die_speed' when mob dies
'*_loop' bool value to determine if any set animation loops e.g (die_loop = false)
defaults to true if not set
also 'speed_normal' for compatibility with older mobs for animation speed (deprecated)
The mob api also has some preset variables and functions that it will remember for each mob Custom Definition Functions
---------------------------
'self.health' contains current health of mob (cannot exceed self.hp_max) Along with the above mob registry settings we can also use custom functions to
enhance mob functionality and have them do many interesting things:

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
