Add a living, terrain-aware ecosystem to your game—plants grow, animals forage, predators hunt, and pollinators boost growth.Living Ecosystem lets you add a modular, terrain-aware, game-friendly ecosystem to Unity in minutes. Plants grow and propagate, animals act by role (Herbivore, Predator, Pollinator, Neutral), and emergent loops appear: pollinators visit plants (non-destructive) and linger, giving predators a natural window. Everything is driven by a simple Editor seeding workflow and a live HUD for monitoring.Use cases– Open-world/survival wildlife– Builder/sandbox simulation– Education/visualization (pollination, predator–prey cycles)– Ambient life for exploration gamesKey Features– Flora: GrowthAgent with ageing, visual growth, seeding (radius + local density), optional pollination boost– Fauna: AnimalAgent roles (Herbivore / Predator / Pollinator / Neutral), sense radius, interact distance, energy/hunger, reproduction, post-interact linger– Pollinators: non-destructive plant visits that refill energy and ground flyers for a while (predator window)– Editor Seeding: ratios and filters (height, skip underwater) for one-click population– HUD: multi-camera grid with overlays (role, energy, age, reproduction timers); toggle via hotkey– Terrain Awareness: min/max height and water level respected by seeding– Clean Prefabs: plug-and-play plant/animal prefabs with tiny trigger collidersWhat’s Included– Runtime: GrowthAgent, AnimalAgent, PollinatorEmitter, HerbivoreEmitter– Editor: Terrain (height/water), Flora & Fauna lists, Seeding tools– HUD: multi-camera grid and overlays– Sample scenes: Archipelago, Plains, Valley– Docs: full website (MkDocs Material) + quick startQuick StartOpen Terrain, set Min/Max Height and Water Level, then Generate.Prepare prefabs: add GrowthAgent to plants and AnimalAgent to animals (keep a small trigger collider on the root).In Flora/Fauna, add prefabs and set ratios/counts; enable Skip Underwater.Click Spawn, press Play, toggle the HUD to monitor.Technical Details– Unity: 2022.3 LTS or newer (tested on Unity 6)– Render Pipelines: Built-in, URP, HDRP (gameplay scripts only)– Dependencies: none (NavMesh optional; Cinemachine optional)– Platforms: Windows, macOS (editor + standalone)– Performance: proximity queries; keep sense radius reasonable; HUD cameras are the biggest GPU costNotes-Some screenshots and demo setups may use third-party or free sample assets(such as vegetation, characters, or skyboxes) for illustration only.These third-party assets are NOT included in the package.Please import your own assets or the original free packages separatelyaccording to their licenses. Example video shows how to use prefabs.-This is a game-friendly ecosystem (not a scientific model). Parameters are exposed for stability and readability.Support & DocsDocumentationEmail: info@pixitgames.comChangelogv1.0.0 — Initial release: flora growth/seeding, fauna roles (Herbivore/Predator/Pollinator/Neutral), editor seeding, HUD.Requires Unity: 2022.3 LTS or newer (Unity 6 compatible)Render Pipelines: Built-in, URP, HDRPPlatforms: Windows, macOSDependencies: None (NavMesh/Cinemachine optional)Content: Runtime scripts, Editor tools, HUD, sample scenes & prefabs, documentationSome elements of this package were developed with the assistance of AI tools (e.g. ChatGPT), such as initial code structure suggestions, inline comments and documentation text. Core implementation, architecture decisions, optimizations and final testing were performed by the author. All AI-assisted content was reviewed and adjusted to comply with Unity Asset Store guidelines.
