Procedural 2D World Framework. TerraFlux2D is a modular, multiplayer-ready framework for creating infinite procedural 2D worlds in Unity. Deterministic generation, chunk streaming, a lobby with numeric room codes, 4 seasons, and persistent decorations — all included and ready to extend.
Infinite worlds via 3-layer Perlin Noise (height, temperature, moisture). Same seed always produces the identical world.
World split into square chunks. Generated server-side and streamed to clients. Only nearby chunks are kept in memory.
Plains, Forest, Desert, Swamp, Winter, Beach, Ocean — each with unique tiles, trees, rocks and decoration spawn rules.
Deterministic trees, rocks and flowers per chunk. Destroyed objects persist permanently and never respawn after deletion.
Spring, Summer, Autumn, Winter — synced over network with smooth tile transitions. Season state saved per world.
Auto-save every 5 min. Saves metadata, destroyed decorations and season as human-readable JSON files.
6-digit numeric room codes. Host creates, friends join by code — no IP address required. Ready-state system included.
Server-authoritative world gen and chunk streaming. Seed synced to all clients on join. Supports host and dedicated server.
