Bukkit

area-filter:
    - Minecart isMounted

chunk-entity-limiter:
  enabled: true
  limit: 10
  entities:
    - Pig name="Testing"
    - Zombie hasName
    - Minecart !isMounted


You're able to define more then one entity of the same type, like so:

entities:
   - Item id=1
   - Item id=2
   - Pig name="bob7l"
   - Pig name="Joe"



Configuring Custom Entity Removal

The "custom-trigger-removal" section of the configuration allows you to get more technical, and custom with the way you want to handle certain conditions of your server such as TPS levels, and entity counts. Being that this is the initial release, there isn't too many options yet. I plan to add onto this in time.

How to specify a trigger:
A trigger is what executes your jobs. You may specify UNLIMITED triggers, BUT all must have a UNIQUE name due to how YAML parses the config file. By default, I specify each with trigger1, trigger2, ect. How you name them is entirely up to you as long as they're valid YAML keys (No spaces)

"run-interval" specifies, in seconds, how often that trigger's conditions should be checked. 

To specify a trigger (REQUIRED), you must put the trigger type under "trigger-type:". Each trigger requires different variables to operate correctly so make sure you specify them under the trigger type.

Trigger types:

tps-trigger: This trigger will execute your jobs once your TPS hits below your specified "tps-trigger" target, and will disable upon reaching your "tps-recover" target. 

entity-limit-trigger: This trigger executes all your jobs once the specified entity limits are reached. For this to function, you must specify a "limit", a list of entities to be counted "entity-limits", and you may optionally specify worlds to be filtered (Not checked) using "world-filter:". Examples of all of this are shown below. 

Jobs: 
Jobs are what execute after a trigger's conditions are met. Some jobs will prevent the trigger's from releasing (Warning's). You may specify multiple jobs as long as they're different types. You cannot specify multiple jobs of the same type.

ALL jobs may be given warning countdowns - or just delay's if you decide not to specify any warnings. All you need to do is add "execute-job-time", and put the time in seconds it should take until the job is executed. Then, if you'd like warning messages, just like auto-removal - you need to add "warnings:", and put your warnings below. An example of this is started below.

Job types:

entity-clearer: This cleaner job removes the entities you specify under "remove-entities". In order to filter out worlds (NOT remove from), you need to specify their names under "world-filter:".

command-executor: This job executes all the commands under "commands:" you want to be executed after the trigger's conditions are met. After the trigger recovers, all the commands under "recover-commands" are then executed. 

Examples:
(Sorry for format, dev.bukkit.org is very buggy/broken)
