EvoBiomes

Dynamic biome evolution for Paper/Spigot/Purpur. EvoBiomes gradually transitions selected regions through configurable biome chains (e.g., Plains → Savanna → Desert), applying visual and ecosystem effects along the way.

Highlights

• Configurable biome evolution chains and transitional effects
• Gradual transitions: particles, messages, entities, and blocks
• Async selection, safe main-thread world updates
• Live‑reloadable rules (rules.yml in plugin data folder)
• Weather-aware pacing and player-density slowdowns (with TTL)
• Admin commands and developer API hooks

Compatibility

• Servers: Paper/Spigot/Purpur
• Versions: 1.20, 1.20.1–1.20.6, 1.21, 1.21.1–1.21.10
• Built against spigot-api 1.20.1 with api-version: 1.20 for forward compatibility

Installation

• Drop EvoBiomes-1.0.0.jar into plugins
• Start the server to generate config and rules
• Optional: edit plugins/EvoBiomes/rules.yml and run /evobiomes reload

Commands

• /evobiomes info — show runtime settings
• /evobiomes reload — reload config and rules from disk
• /evobiomes evolve <biome> <radius> — force-evolve area around the player

Permissions

• evobiomes.admin — access to all evobiomes commands (default: op)

Configuration

config.yml

• safe_mode: limit biome updates per tick (default: true)
• max_chunk_updates_per_tick: budget for chunk processing (default: 5)
• cycle_interval_ticks: evolution cycle interval (default: 1200)
• worlds: list of world names to process
• use_protocol_lib: visual enhancements toggle (no compile dependency; falls back to Bukkit particles)
• transitions: toggles for messages, particles, entities, blocks
• player_density: radius, slowdown_factor
• weather: rain_acceleration, thunder_acceleration, clear_slowdown

Rules & Effects

rules.yml (data folder)

• chains define ordered biome sequences per starting biome
• effects define transitional effects between steps using key from->to
• Effects include lists: entities, blocks, particles, and message

Example chains:

• plains: [savanna, desert]
• forest: [dark_forest, jungle]
• taiga: [snowy_taiga, ice_spikes]

How It Works

• Scheduler runs asynchronously to select chunks; each chunk’s work is executed on the main thread for safety
• Transitional effects are applied before the biome switch (particles/messages/entities/blocks)
• Temperature/humidity hints are shown to nearby players
• Weather and player density modify pacing without blocking the server
