ChunkMonitor

ChunkMonitor is a Paper plugin that helps you spot players causing lag by monitoring chunk generation. Ever wonder why your TPS drops? This plugin shows you who’s generating the most chunks in real-time!

Features

- Monitors chunk generation in real-time. - Displays a boss bar showing the player generating the most chunks per minute. - Boss bar changes color based on the rate of chunk generation: - Red for low generation. - Red for medium generation. - Red for high generation. - Updates chunk generation statistics at a configurable interval. - Supports player joining with the boss bar being displayed if necessary.

In-game picture

- Low chunk generation

- Medium chunk generation

- High chunk generation

Compatibility

This is a Paper plugin and will not work with Spigot servers, but Purpur is fine.

I don't know if any version other than `1.21.5` would work, because that's the only version I tested.

Configuration

You can adjust the plugin’s behavior using the configuration file (`config.yml`), which is generated upon enabling the plugin.

Available Configuration Options:

- `update-interval-ticks`: - The interval (in ticks) at which chunk statistics are updated. - Default: `20` (1 second)

- `min-display-threshold`: - The minimum chunk generation rate required to display the boss bar. - Default: `250.0` (chunks per minute)

- `yellow-threshold`: - The chunk generation rate at which the boss bar color changes to yellow. - Default: `500.0` (chunks per minute)

- `red-threshold`: - The chunk generation rate at which the boss bar color changes to red. - Default: `1000.0` (chunks per minute)

- `maxAttributionDistance`: - The maximum distance a player can be from a chunk to be counted as the "nearest" player generating the chunk. - Default: `50.0` (blocks)

Since this is my first Java plugin project. This plugin was created with the help of the ChatGPT, ChatGPT and ChatGPT. (I know it's stupid)
