Spawners in vanilla Minecraft are infinite mob factories — set up a farm once and it runs forever. Decaying Spawners changes that. Each spawner has a limited lifespan: once it has spawned enough mobs (or been active long enough), it burns out and stops working permanently.
Configuration
Configuration is loaded from:
config/btwr/decaying_spawners/decaying_spawners.json
| Option | Default | Description |
|---|---|---|
maxMobSpawnCount |
12 |
How many mobs a spawner can spawn before decaying. Set to -1 to disable. |
maxSpawnerTicks |
-1 |
How many active ticks a spawner can run before decaying. Set to -1 to disable. |
excludedSpawners |
[] |
A list of entity IDs whose spawners will never decay. |
Example config:
{
"maxMobSpawnCount": 20,
"maxSpawnerTicks": -1,
"excludedSpawners": [
"minecraft:blaze",
"minecraft:silverfish"
]
}
Changes to the config file take effect the next time you load a world
