Description

Disable unwanted mobs from spawning using JSON configuration.
Supports Forge, Fabric and Quilt
⭐ Features ⭐
- Disable Entity Spawning
Add the ID of the entity you want to remove in config/ysns/disabled_entities.json5 to completely remove entities from spawning.
- Control Entity Spawning
Whether per dimension or globally (by using "!.*"), you can control the spawn rate of an entity in the config/ysns/per_dimension_entities.json5 config.
- Regex Support
Need to disable multiple entities from 1 mod? Or is there a pattern in them? Then no need to repeat yourself!
With regular expressions, you can disable multiple entities in a single entry, disable all entities from a mod, and a lot more!
Simply start the entry with "!" and then write your regular expression.
- Commented Config File
The config files have comments explaining and giving examples of what you need to add to make the mod work!

FAQ
- Can I use this in my modpack?
Of course! It was designed for modpack creators to remove undesired entities that may unbalance the game or
create issues.
- Can I still make the entities spawn?
In the case of using the disabled_entities config, no. Once a mob is added to the blacklist, there is no way to spawn it by any method.
Both natural or through eggs/commands. This mod is meant to completely remove undesired entities.
In the case of the per_dimension config, it works via chance, so at 0.0 they won't spawn at any way. But at 0.5 it'll have 50% chance of spawning.
- Client or server?
Everything happens on the server's side. Though it is recommended to leave the mod and config for clients too,
for the case they want to play a single player world. You should always leave this mod in the server pack alongisde its config.
- What if I add an entity to blacklist that was already spawned?
Spawned entities will still exist, so it's up to you if you want to kill them or not.
For this reason it's recommended to configure the mod before creating a world
- What if I mispell an entitity's ID in the config file?
Nothing will happen. Adding invalid ID's won't cause issues, but obviously the entity won't be blacklisted
as it technically doesn't exist. Same thing would happen if the mod isn't present, but it will be if it's added later and the ID is valid.
