Description:
|
||||
--------------------
|
||||
Advances spawning mod is designed to provide a feature rich yet easy to use
|
||||
spawner for entites. It's purpose is to support spawning within large numbers
|
||||
of different environments. While adv_spawning supports a wide configurable range
|
||||
of spawning situations, it's performance impact is clamped at minimal level.
|
||||
To achiev this performance goal adv_spawning is intended for low frequency
|
||||
entity spawning only. Tyyical spawn rate will be a low single digit count of
|
||||
entities per second throughout whole world.
|
||||
|
||||
|
||||
API:
|
||||
--------------------
|
||||
adv_spawning.register(spawner_name,spawning_def) --> successfull true/false
|
||||
^ register a spawn to adv_spawning mechanisms
|
||||
^ spawner_name a unique spawner name
|
||||
^ spawning_def is configuration of spawner
|
||||
|
||||
adv_spawning.statistics() --> statistics data about spawning
|
||||
