Adaptive Range Mob Spawner (ARMS)
The Adaptive Range Mob Spawner (ARMS) plugin dynamically adjusts the activation range of spawners in Minecraft based on the server's TPS (Ticks Per Second), ensuring optimal performance while maximizing mob spawn rates. It improves gameplay by maintaining a balance between efficient mob farming and server stability, even during high player activity.
Key Features
Dynamic Activation Range Adjustment: Automatically adjusts the spawner's activation range between a low and high threshold based on the server's TPS.
When TPS is high, the range increases to maximize mob spawning.
When TPS drops below the configured threshold, the range decreases to reduce server load.
Player-Defined Range Control:
Initial, low, and high ranges can be defined in the configuration to meet server needs.
Set a custom initial range for placed spawners.
Automatically revert to a vanilla range for naturally generated spawners (optional).
Intelligent Chunk Management:
Only updates chunks near active players to reduce unnecessary processing.
Preexisting spawners can optionally be treated as player-placed for backward compatibility.
Auto-Update on Chunk Load:
Ensures spawners update dynamically when a chunk is loaded or when the TPS status changes.
Persistent Player-Placed Spawner Tagging:
Spawners placed by players are marked with persistent data, ensuring that only marked spawners retain adjusted ranges while natural spawners can be left unaffected.
Startup and Manual Update Options:
Automatically updates all loaded chunks on server startup.
Force-update all spawners manually with a command.
Configuration Options
The plugin offers an extensive configuration file to customize its behavior:
Range Settings:
initial-spawner-range: Initial range for player-placed spawners.
spawner-range-high: Range when TPS is high.
spawner-range-low: Range when TPS is low.
TPS Thresholds:
tps-threshold-low: TPS level to reduce the range.
tps-threshold-high: TPS level to restore a higher range.
Chunk Management:
only-update-near-players: Limit updates to chunks near active players.
player-chunk-radius: Radius of chunks around players to monitor.
World Control:
disabled-worlds: List of worlds where the plugin should be disabled (e.g., the_nether, the_end).
Spawner Update Policies:
affect-naturally-generated: Whether to update naturally generated spawners.
update-preexisting-spawners: Whether to update preexisting spawners without a player-placed marker.
