# EvoBiomes<\/p>\n
Dynamic biome evolution for Paper\/Spigot\/Purpur. EvoBiomes gradually transitions selected regions through configurable biome chains (e.g., Plains \u2192 Savanna \u2192 Desert), applying visual and ecosystem effects along the way.<\/p>\n
## Highlights
\n– Configurable biome evolution chains and transitional effects
\n– Gradual transitions: particles, messages, entities, and blocks
\n– Async selection, safe main-thread world updates
\n– Live\u2011reloadable rules (`rules.yml` in plugin data folder)
\n– Weather-aware pacing and player-density slowdowns (with TTL)
\n– Admin commands and developer API hooks<\/p>\n
## Compatibility
\n– Servers: Paper\/Spigot\/Purpur
\n– Versions: 1.20, 1.20.1\u20131.20.6, 1.21, 1.21.1\u20131.21.10
\n– Built against `spigot-api 1.20.1` with `api-version: 1.20` for forward compatibility<\/p>\n
## Installation
\n– Drop `EvoBiomes-1.0.0.jar` into `plugins`
\n– Start the server to generate config and rules
\n– Optional: edit `plugins\/EvoBiomes\/rules.yml` and run `\/evobiomes reload`<\/p>\n

\n– `\/evobiomes info` \u2014 show runtime settings
\n– `\/evobiomes reload` \u2014 reload config and rules from disk
\n– `\/evobiomes evolve
\n– `evobiomes.admin` \u2014 access to all `evobiomes` commands (default: op)<\/p>\n
\n`config.yml`
\n– `safe_mode`: limit biome updates per tick (default: true)
\n– `max_chunk_updates_per_tick`: budget for chunk processing (default: 5)
\n– `cycle_interval_ticks`: evolution cycle interval (default: 1200)
\n– `worlds`: list of world names to process
\n– `use_protocol_lib`: visual enhancements toggle (no compile dependency; falls back to Bukkit particles)
\n– `transitions`: toggles for `messages`, `particles`, `entities`, `blocks`
\n– `player_density`: `radius`, `slowdown_factor`
\n– `weather`: `rain_acceleration`, `thunder_acceleration`, `clear_slowdown`<\/p>\n
\n`rules.yml` (data folder)
\n– `chains` define ordered biome sequences per starting biome
\n– `effects` define transitional effects between steps using key `from->to`
\n– Effects include lists: `entities`, `blocks`, `particles`, and `message`<\/p>\n
\n– `plains: [savanna, desert]`
\n– `forest: [dark_forest, jungle]`
\n– `taiga: [snowy_taiga, ice_spikes]`<\/p>\n
\n– Scheduler runs asynchronously to select chunks; each chunk\u2019s work is executed on the main thread for safety
\n– Transitional effects are applied before the biome switch (particles\/messages\/entities\/blocks)
\n– Temperature\/humidity hints are shown to nearby players
\n– Weather and player density modify pacing without blocking the server<\/p>\n","protected":false},"excerpt":{"rendered":"
