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)
'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)
'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.
Registering Mobs
----------------
mobs:register_mob(name, definition)
To register a mob and have it ready for use requires the following function:

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_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)' gets 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
'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.
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
'fly_start', 'fly_end', 'fly_speed' when mob flies
'punch_start', 'punch_end', 'punch_speed' when mob attacks
'punch2_start', 'punch2_end', 'punch2_speed' when mob attacks (alternative)
'shoot_start', 'shoot_end', shoot_speed' when mob shoots
'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)
By default, replacing sets self.gotten to true and resets the object
properties.
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:
'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 (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.

for each mob.

'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.
