Wild Creatures

🐾 Wild Creatures 1.2.1 – Performance & Worldgen Update

Minecraft 1.21.1 • Fabric

This update focuses heavily on server stability, world generation safety and multiplayer performance, especially when 4+ players are exploring different areas at the same time. 🚀

🌍 Worldgen & Spawning Fixes

• Fixed unsafe cross-chunk terrain reads during natural spawning.
• Reworked Duck, Duckling and Crocodile terrain and water checks.
• Water preference now runs through throttled runtime AI instead of expensive worldgen radius scans.
• Duck and Crocodile natural spawning remains enabled in their intended biomes. 🦆🐊
• Prevented Wild Creatures spawn/path checks from intentionally reading unloaded neighboring chunks.

⚡ Multiplayer Performance

• Completely optimized the custom Water Creature Spawner.
• Players in the same area are now grouped into regions instead of scanning the same surroundings repeatedly.
• Added fixed per-world spawn and work budgets.
• Custom spawn checks now use already loaded chunks only.
• Replaced large vertical ocean scans with cached heightmap lookups.
• Added successful and failed water-area caching to avoid repeated expensive checks.
• Reduced the custom spawner frequency and number of position attempts.

🧠 Entity & AI Optimizations

• Major Mussel seabed and tick-performance optimization.
• Reduced Jellyfish player-contact queries.
• Reduced water-target searches for Sharks, Orcas and Crabs.
• Optimized player-targeting logic for several territorial and hostile creatures.
• Reduced unnecessary block, fluid and entity queries across the mod.
• Added loaded-chunk safety checks to several runtime movement searches.

✅ Multiplayer Recommendation

Wild Creatures 1.2.1 is strongly recommended for multiplayer servers, especially servers where several players explore and generate new chunks simultaneously.

Thank you for reporting the performance problems and helping improve Wild Creatures! ❤️🐾
