About this Mod
compactspawners
Fabric/Quilt mod, that adds automatic killing and drop storing in spawners
This mod changes the behaviour of the spawner to a fully automated killing machine. This way mobs don't spawn in the
world the drops and experience are stored in the spawner.
Deprecation
This project is archived from 15/04/2024 on. This is caused by the bad implementation of this project and my lack of time.
It is possible I revive this project at a later time. Feel free to fork or reimplement this project.
Interactions
- Hitting or clicking on the spawner will transfer the experience to your character.
- Clicking on the spawner will open the drop menu.
- Clicking on a spawner with a spawner will add more spawners to the hosting spawner. This will increase the kill rate.
- A hopper below the spawner will suck up all mob drops.
Config
The mod can be configured via the mod file, which is stored in .minecraft/config/compactspawners.json, or via the
configuration menu in ModMenu.
compactspawners.json
{
"maxMergedSpawners": -1, // defines the number of spawners that can be merged into one
"maxStoredExp": -1, // the maximum amount of experience stored in a hosting spawner
"silkBreakSpawners": true, // decides whether you can break a spawner with silk touch
"requiredPlayerDistance": 32, // the minimum player distance for the spawner to work
"mobsPerSpawner": 4, // defines how many mobs should spawn per spawner per period
"luck": 1.0 // defines with what value of luck an entity should be killed inside a spawner
}
Recipes
As long as Minecraft doesn't intend to add nbt crafting, there will be no recipes provided by this mod. I hope to be able to add
configurable spawner recipes in the future.
