For developers:
This mod add some functions that you can use in other mods:
1. mobs:register_monster(name, def)
1. mobs:register_mob(name, def)
This adds a monster to Minetest that will attack the player
"name" is the name of the monster ("[modname]:[monstername]")
"def" is a table with the following values:
type: the type of the mob ("monster" or "animal")
hp_max: same is in minetest.register_entity()
physical: same is in minetest.register_entity()
collisionbox: same is in minetest.register_entity()
@ -47,24 +48,14 @@ This mod add some functions that you can use in other mods:
walk_velocity: the velocity when the monster is walking around
run_velocity: the velocity when the monster is attacking a player
damage: the damage per second
light_resistant: light wont cause damage on day
drop: the drop item of the monster
drop_count: the number of items that are dropped
armor: the armor (integer)(3=lowest; 1=highest)(fleshy group is used)
drawtype: "front" or "side"
water_damage: the damage per second if the mob is in water
lava_damage: the damage per second if the mob is in lava
2. mobs:register_animal(name, def)
This adds a animal to Minetest that will just walk arround
"name" is the name of the monster ("[modname]:[animalname]")
"def" is the same table as in register_monster but without these values:
-view_range
-run_velocity
-damage
-light_resistant
-armor
and it also has the field
-on_rightclick: its same as in minetest.register_entity()
light_damage: the damage per second if the mob is in light
on_rightclick: its same as in minetest.register_entity()
3. mobs:register_spawn(name, nodes, max_light, min_light, chance, mobs_per_30_block_radius)
This function adds the spawning of an animal (without it the
registered animals and monster won't spawn!)
