AEO - Anti Entity Overload

AEO is a datapack that helps prevent lagging and crashing from having too many entities by killing new ones if they surpass a specified limit.

Disclaimer!

This datapack kills entities! Be aware of this and backup your world before installing it. Please do not hold me responsible if it kills something it was not meant too. Use caution if you edit this datapack.

Installation

You can download the datapack under releases: https://github.com/iRedSC/anti-entity-overload/releases (download source-code.zip)

All you have to do is put the datapack in your datapacks folder and reload.

Debug Mode

To enabled/disable debug mode run:

function aeo:debug-mode

Debug mode will display bossbars that will show you the entity count for each of the five catagories, as well as the configured limit:

• All Entities
• TNT
• Items
• Projectiles
• Inanimates (Armor Stands, Boats, Item Frames, etc.)

Configuration

There are two configureable files in the datapack: data/aeo/functions/setup/config.mcfunction and data/aeo/functions/setup/messages.mcfunction.

Config.mcfunction

# THIS IS A PREVIEW OF THE CONFIG FILE

# Max limits
#
# Limits to the amount of each type of entity allowed to be loaded before AEO attempts to reduce them
#
# This includes ALL entites (Including tagged ones)
scoreboard players set $type.all.limit irsc.aeo.global 1000
# Kills even new tagged entities when the total entity count passes this value
scoreboard players set $type.all-tagged.limit irsc.aeo.global 1500

# Tnt limit
scoreboard players set $type.tnt.limit irsc.aeo.global 500

# Projectile limit (arrows, snowballs, shulker bullets)
# ENDER PEARLS ARE EXCLUDED DUE TO IT POSSIBLY AFFECT PEARL STASIS ETC
# List of entities defined in the entity tag "aeo:type/projectile"
scoreboard players set $type.projectile.limit irsc.aeo.global 200

You can change the entity limits for each of the these catagories:

• All Entities
  • All Entities (Including tagged ones)
• TNT
• Items
• Projectiles
• Inanimates (Armor Stands, Boats, Item Frames, etc.) You can also change the:
• Duration of lagclears (clearing items)
• Bossbar display colors (for displaying entity counts)

It is suggested that you increase the entity limits if possible (your computer/server can handle it), this datapack is meant as a last resort and should only trigger after the game starts becoming unplayable from entity lag.

Messages.mcfunction

# THIS IS AN EXAMPLE OF THE MESSAGE CONFIG

## global prefix
# This prefixes all AEO messages
data modify storage irsc.aeo:messages message-prefix set value '["",{"text":"[","color":"gold"},{"text":"AEO","color":"dark_red","hoverEvent":{"action":"show_text","contents":[{"text":"Anti Entity Overload","color":"dark_red"}]}},{"text":"] ","color":"gold"}]'

## limiting messages
# Displays when AEO is trying to limit an entity count
data modify storage irsc.aeo:messages limiting.attempt set value '{"text":"Attempting to limit ","color":"red"}'

# Limit all entities message
data modify storage irsc.aeo:messages limiting.all set value '{"text":"ALL ENTITIES","color":"gold"}'

# Limit all entities including tagged entities message
data modify storage irsc.aeo:messages limiting.all-tagged set value '{"text":"ALL ENTITIES [INCLUDING TAGGED]","color":"gold"}'

# Limit all items message (Lagclear critical)
data modify storage irsc.aeo:messages limiting.item set value '{"text":"ITEMS","color":"light_purple"}'

You can modify the messages for everything in the datapack including the:

• [AEO] message prefix
• Lagclear Messages
• "Attempting to limit" Messages
• The debug display bossbar titles

Messages just use standard minecraft json format.

Uninstallation

There is an uninstallation function if you no longer want the datapack in your world:

function aeo:setup/uninstall

this should remove everything, althought players who are offline and have the irsc.aeo.debug tag will not have it removed (online players will)
