creatures.register_mob(#Creature definition)
|
||
|
|
-registers a mob at MOB-Engine; returns true when sucessfull
|
||
|
|
|
||
|
|
creatures.rnd(chance_table)
|
||
|
|
-returns a weighted random table element; chance_sum of table must be 1
|
||
|
|
^ example: creatures.rnd({elem1 = {chance = 0.7}, {elem2 = {chance = 0.3}})
|
||
|
|
|
||
|
|
creatures.compare_pos(pos1, pos2)
|
||
|
|
-returns true if pos1 == pos2
|
||
|
|
|
||
|
|
creatures.findTarget(search_obj, pos, radius, search_type, mob_name, xray, no_count)
|
||
|
|
-returns table of found objects (as ObjectRef) and boolean player_near
|
||
|
|
^ search_obj is searching object; can be nil
|
||
|
|
^ pos is starting position for search radius
|
||
|
|
^ radius for searching in blocks/node
|
||
|
|
^ search_type that specifies returned object requirements
|
||
|
|
^ "all" -- returns every object except dropped Items
|
||
|
|
^ "hostile" -- returns every object(creature) that has hostile setting or is player
|
||
|
|
^ ignores "mob_type" if specified
|
||
|
|
^ "nonhostile" -- returns every object that is not hostile or player
|
||
|
|
^ "player" -- returns all players
|
||
|
|
^ "mates" -- returns all objects(creatures) that are of same kind
|
||
|
|
^ requires "mob_type" specifies
|
||
|
|
^ mob_type specifies creature that is ignored or searched, depending on search_type
|
||
|
|
^ xray allows searching through blocks/nodes (default == false)
|
||
|
|
^ no_count skips collecting loop and returns just the boolean player_near
|
||
|
|
^ table is empty
|
||
|
|
|
||
|
|
creatures.dropItems(pos, drops)
|
||
|
|
-drops items at position pos
|
||
|
|
^ pos where to drop Items
|
||
|
|
^ drops table in #ItemDrops format
|
||
|
|
|

Example:

|
Will drop with a chance of 30% 1 to 3 items of type "default:wood"
|

and with a chance of 100% 2 items of type "default:stone"
