# 🌿 Ecosystem Life Simulator
|
||||||
|
|
||||||
|
An interactive, pixelated ecosystem simulation built with pure **HTML5 Canvas, CSS3, and Vanilla JavaScript (ES Modules)**.
|
||||||
|
|
||||||
|
Observe predator-prey dynamics, biological lifecycles, carcass decomposition, floral blooming cycles, seed dispersal, and periodic rainstorms in a living sandbox meadow.

## 🌟 Key Features & Mechanics
|
||||||
|
|
||||||
|
### 1. 🐑 Sheep Grazing & Herd Behavior
|
||||||
|
* **Rapid Grazing (Node Removal):** Sheep are ravenous grazers. When a sheep reaches a plant, it instantly consumes and removes the entire plant node from the field. A herd of sheep can sweep through and clear an entire field in moments.
|
||||||
|
* **Grazing Reach & Hunger:** Sheep continuously search for food whenever hunger drops below 96%, with a configurable grazing reach.
|
||||||
|
* **Mating & 3-Meal Growth:** Satiated adult sheep seek mates and collide to birth a baby lamb. Baby lambs start at 55% scale and grow larger with each meal until reaching adult size after **3 meals**.
|
||||||
|
* **Evasion:** Sheep actively detect wolves in their perception radius and flee with a panic speed boost.
|
||||||
|
|
||||||
|
### 2. 🐺 Wolf Hunting, Combat Exertion & Population Controls
|
||||||
|
* **Combat Exertion (Lunge Health Cost):** Wolves expend health every time they deliver an attack bite. Reckless over-hunting without resting or eating inflicts stamina fatigue and damage.
|
||||||
|
* **Chase Drain:** Wolves expend hunger 50% faster while actively sprinting in hunt mode.
|
||||||
|
* **Controlled Reproduction:** Wolves require high satiety (86%+) and a long mating cooldown (35s+) to reproduce, preventing runaway wolf swarms from wiping out the sheep population unchecked.
|
||||||
|
* **Feeding:** Defeating a sheep restores hunger. Wolf pups must eat **3 meals** to mature into adult wolves.
|
||||||
|
|
||||||
|
### 3. 💀 Carcass Decay & Soil Enrichment
|
||||||
|
* **Decay Cycle:** Dead animals leave carcasses that decompose through flesh and skeletal stages before dissolving into rich brown soil mulch.
|
||||||
|
* **Decay Speed Slider:** Adjust decomposition rate from 0.2x to 3.0x.
|
||||||
|
* **Floral Blooms:** Fully decomposed remains fertilize the ground and trigger a **lush Flower Tuft** to sprout on the enriched soil.
|
||||||
|
|
||||||
|
### 4. 🌸 Flora Dynamics, Seed Dispersal & CPU Guard
|
||||||
|
* **Max Plant Cap (CPU Guard):** Strict upper ceiling slider (default: 90) preventing plant overpopulation and keeping framerates rock-solid.
|
||||||
|
* **Low Seed Spread Rate:** Mature, clustered plants have a rare chance (configurable, default 8%) to release an airborne dandelion seed that lands nearby.
|
||||||
|
* **Moisture & Withering:** Plants lose moisture during dry weather and wither away if unhydrated.
|
||||||
|
* **Periodic Rain:** Rain showers roll across the meadow periodically (or on demand), reviving all flora to 100% moisture.
|
||||||
|
|
||||||
|
### 5. 🎛️ Comprehensive State Sliders & Presets
|
||||||
|
* **Populations & Caps:**
|
||||||
|
* Initial Sheep (2 - 80)
|
||||||
|
* Initial Wolves (1 - 20)
|
||||||
|
* Initial Plants (5 - 100)
|
||||||
|
* Max Plant Cap (20 - 300)
|
||||||
|
* **Sheep Dynamics:**
|
||||||
|
* Sheep Hunger Depletion Rate (0.2 - 3.0/s)
|
||||||
|
* Grazing Reach (10 - 35px)
|
||||||
|
* Sheep Mating Cooldown (10 - 60s)
|
||||||
|
* **Wolf Dynamics:**
|
||||||
|
* Wolf Lunge Health Cost (0 - 20 HP)
|
||||||
|
* Wolf Hunger Rate (0.5 - 3.5/s)
|
||||||
|
* Attack Bite Damage (15 - 80)
|
||||||
|
* Wolf Mating Cooldown (15 - 80s)
|
||||||
|
* **Flora & Atmosphere:**
|
||||||
|
* Plant Seed Spread Chance (0 - 40%)
|
||||||
|
* Plant Withering Speed (0.5 - 6.0/s)
|
||||||
|
* Rain Frequency (0 - 100%)
|
||||||
|
* Carcass Decay Speed (0.2x - 3.0x)
|
||||||
|
* **Preset Configuration Tools:**
|
||||||
|
* **💾 Save As Defaults:** Saves your customized slider configuration to `localStorage` as your new default baseline.
|
||||||
|
* **↺ Reset:** Reverts all sliders to your saved defaults.
|
||||||
|
* **📋 Copy JSON:** Copies the current configuration object to your clipboard for sharing or manual tuning.
|
||||||
|
|
||||||
|
### 6. 📊 Extinction Event & Analytics
|
||||||
|
* If all animals perish, an extinction modal appears with an interactive population timeline chart (Sheep, Wolves, Plants) and detailed ecosystem stats.
