Cow Life Simulator is a simple simulation designed to explore how different environmental factors and settings affect a cow population.
The goal of the game is to experiment with life-affecting variables: Will the herd thrive and grow, will they face extinction, or can you find the perfect balance to maintain a stable population?
The simulation field consists of a 50x50 grid (2,500 cells).
- Green cell: Fresh grass.
- Grey cell: Eaten/depleted grass.
- White/Black symbol: A hungry cow searching for food.
- Yellow/Black symbol: A cow currently eating.
- Red/Black symbol: A sick cow.
- Blue cell: Water (impassable).
- Brown cell: Rocks (impassable).
- Searching: A hungry cow searches for grass within a 5x5 cell radius.
- Movement: If no grass is found, the cow moves in a random direction.
- Eating: When a cow finds grass, it stays stationary to eat. You can customize how long the eating process takes.
You can customize the following parameters in real-time:
- Starting Population: Initial number of cows.
- Grass Growth Time: Seconds it takes for a cell to regrow grass.
- Eating Duration: Seconds a cow spends eating one cell of grass.
- Starvation Limit: How many seconds a cow can survive without food.
- Reproduction Chance: Probability (%) of successful breeding.
- Illness Chance: Probability (%) of a cow becoming sick.
- Illness Fatality: Probability (%) of a sick cow dying.
- Maximum Age: Lifespan of a cow in seconds (0 = off).
- Illness: A sick cow can still move, eat, and reproduce. After 25 seconds, the cow will either recover or die based on the "Illness Fatality" setting.
- Breeding Requirements: Two cows can reproduce if:
- They are in adjacent cells.
- At least one of the cows is currently eating.
- Both cows are older than 10% of the set "Maximum Age" (or at least 50 seconds old if Max Age is set to 0).
Population Cap: The population is capped at 2,100 cows to ensure stability and performance, accounting for the space taken by rocks and water.
To simulate a realistic ecosystem, the simulator features an overgrazing mechanic. When the cow population grows too large, the environment struggles to recover, causing grass to grow slower.
- Optimal Conditions: As long as the population is below 200 cows, grass grows at the base rate selected in the settings.
- Overgrazing Penalty: Once the population exceeds 200, a penalty factor is applied.
- Effective Growth Time = Base Rate * ((Cow Count / 100) * 0.5)
When overgrazing is active, a red multiplier (e.g., 2.50x) will appear next to the Grass growth time label in the UI, indicating the current environmental strain.
In this simulation, managing your herd size is a balance between profit and peril. If the population grows too large, nature will intervene.
There are three types of disasters that can strike your farm.
| Disaster | Impact |
|---|---|
| 🦠 Disease Outbreak | A devastating plague that wipes out 70% of your entire herd. |
| 🔥 Fire | Approximately 50% of the farm area burns. All grass and cows within the affected area are lost. |
| 🌊 Flood | Approximately 70% of the area is submerged. All grass and cows in the flood zone are lost. |
The chance of a disaster occurring is dynamic. It scales with your herd size. Once you surpass 200 cows, the environment becomes significantly more unstable.
- 50 Cows:
0.1%(Stable / Low risk) - 350 Cows:
0.45%(Warning signs / Risk has quadrupled) - 500 Cows:
1.0%(High risk / Rapid escalation) - 750 Cows:
2.8%(Critical danger) - 1000+ Cows:
5.0%(Extreme peril / Near-constant disasters)
Pro Tip: Keep your herd manageable to avoid total collapse. Large-scale farming comes with large-scale consequences!
- Localization: Support for multiple languages.
- Save/Load: Save your custom game settings to a file or load previously saved configurations.
- Reset: Restarts the simulation. This clears the field and resets the population while keeping your current settings.
- Pause/Resume: Use the "Pause" button to halt the simulation and "Resume" to continue.
- Real-time Adjustments: Change settings while the game is running to see immediate reactions.
- Browser Focus: The simulation automatically pauses if you switch browser tabs and resumes when you return.
Have fun and... MOOOOOOO! :)
