Hunger System
Overview
The hunger system tracks how fed an animal is and affects its behavior priorities.
Parameters
| Parameter | Type | Description |
|---|---|---|
| max | float | Maximum hunger value |
| current | float | Current hunger level |
| decay_rate | float | Hunger lost per tick |
| starvation_threshold | float | Level below which starvation occurs |
| starvation_damage | float | Damage dealt when starving |
Hunger Effects
| Hunger Level | Effect |
|---|---|
| 70-100% | Normal behavior |
| 40-70% | Increased food seeking |
| 10-40% | Priority food seeking |
| 0-10% | Starvation damage |
Hunger Restoration
Different food sources restore different amounts:
| Source | Restoration | Example |
|---|---|---|
| Grazing | +25 | Sheep eating grass |
| Crops | +15-25 | Pig eating carrots |
| Prey | +40 | Wolf eating meat |
| Items | Variable | Fed by player |

}Condition System
Overview
Condition represents overall health and well-being beyond just HP.
Parameters
| Parameter | Type | Description |
|---|---|---|
| max | float | Maximum condition value |
| current | float | Current condition level |
Condition Factors
Condition is affected by:
- Hunger level (well-fed = condition gain)
- Starvation (condition loss)
- Mud bathing (condition restoration for pigs)
- Social needs (isolation = condition loss)
- Weather/temperature
Condition Effects
| Condition Level | Effect |
|---|---|
| 80-100% | Optimal behavior, premium outputs |
| 50-80% | Normal behavior |
| 20-50% | Reduced breeding success |
| 0-20% | Impaired behavior, poor outputs |
Output Quality
Condition affects output quality:
| Output | High Condition | Low Condition |
|---|---|---|
| Wool | Premium drops | Reduced drops |
| Breeding | Higher success | Lower success |
| Truffle finding | Better odds | Worse odds |
Configuration
{
"condition": {
"enabled": true,
"max": 100,
"starting": 70,
"hunger_gain_rate": 0.02,
"starvation_loss_rate": 0.05
}
}Social System
Overview
Social needs track how lonely or content an animal is with its social environment.
Parameters
| Parameter | Type | Description |
|---|---|---|
| decay_rate | float | Loneliness increase when alone |
| recovery_rate | float | Loneliness decrease near herd |
| threshold | float | Level at which distress behaviors trigger |
Social Needs by Animal Type
| Animal Type | Social Preference |
|---|---|
| Herd (cow, sheep, pig) | Needs nearby herd |
| Pack (wolf) | Needs pack members |
| Flock (chicken, parrot) | Needs flock |
| Solitary (fox, bat) | Minimal social needs |
Social Effects
| Loneliness Level | Effect |
|---|---|
| 0-40 | Content, normal behavior |
| 40-70 | Seeking company |
| 70-100 | Distress behaviors, condition loss |
Configuration
{
"social": {
"enabled": true,
"herd_radius": 16.0,
"min_herd_size": 3,
"decay_rate": 0.008,
"recovery_rate": 0.1,
"loneliness_threshold": 40
}
}Energy System
Overview
Energy tracks stamina for high-intensity activities like fleeing.
Energy Consumption
| Activity | Energy Cost |
|---|---|
| Walking | Low |
| Running | Medium |
| Fleeing | High |
| Sprinting | Very High |
Energy Recovery
- Resting: Fast recovery
- Walking: Slow recovery
- Eating: Moderate recovery
System Interactions
Hunger -> Condition
if (hunger > 70%) {
condition += gain_rate;
} else if (hunger < starvation_threshold) {
condition -= loss_rate;
}Condition -> Behavior
if (condition < 50%) {
breeding_success *= 0.5;
output_quality *= condition / 100.0;
}Social -> Condition
if (loneliness > threshold) {
condition -= social_loss_rate;
triggerDistressBehaviors();
