Zara is written in C# (3D-engine-agnostic code [at the moment it has one Unity reference, but will be unlinked soon])
Zara will be useful for you if you want your game to have weather-aware health control with ton of intertwined parameters, diseases (flu, food poisoning, venom poisoning, angina and so on), injuries (cuts, fractures), food spoiling, water disinfecting, clothes with different water/sun/cold resistance levels and more. Code is open, so you can customize everything for your particular game needs. On a surface, it is really easy to use. Basic setup is about 10 lines of code – and you have everything at your disposal).
What is missing at the moment -- is save/load mechanic, but I'm already working on it. So you'll be able to serialize Zara state and completely restore it from the save with single line of code.
It includes:
-
Health Engine that controls
- Heart Rate
- Body Temperature
- Blood Pressure
- Stamina (incl. fatigue and exhaustion)
- Food Level
- Water Level
- Blood Level
- Wetness level (how wet is your cloths)
- Warmth level (incl. cloths with different warmth levels)
- Sleep cycles
- Side effects from running, carrying weight, swimming, freezing
- Dizziness and blackouts as a result of an extreme exhaustion and/or medical effects
- Sneezing
- Caughing
- Diseases and injuries and their treatment (see more below)
-
Inventory Engine
- Support for a different item types (handheld, tools, medical items, food (incl. food spoiling), water (incl. disinfection))
- Inventory controller with weight and overweight support
- Crafting engine (any combinations of any number of items in any amounts) "Stick"+"Rope"+"Pin"+"Worm(2)"="Fishing Rod With Bait", including custom actions like "Water+LitTorch"="UnlitTorch"
- Custom validation rules for any crafting recipe
-
Disease Engine
- Create any disease with any effects on a player with any kind of treatment using simple fluent pattern
- Support for self-healing chance for a particular disease
- Support for disease scheduling (i.e. get flu after four in-game hours after being in a cold water, and so on)
- Treatment with pills or injections in any order and with any number of stages
- Timed treatment (to cure X, you need to take the Y pill every four hours, or else disease will become active again)
- Every disease progresses gradually, and treatment inverts the effects, so they go in opposite order -- to the "healthy" state. If the treatment is missed mid-way, disease will invert back and will start to get worse, and you will need to start all the treatment steps from scratch
- Any number of simultanious diseases, injuries and medicine effects: everything will be combined to a single resulted health state
-
Injury Engine
- Cuts, Fractures, Open fratcures, or anything custom you like
- Injuries can cause diseases (deep cut on a later stage can cause blood poisoning, and so on)
- Injuries can cause blood loss, or any other effect on player's health
- Treatment with bandages, splints, pills, injections in any order you like
Supports the following causes of death:
Drowning
From Disease
From Bad Vitals (too low ot too high blood pressure, too low or high body temp. and so on)
Medicine Overdose
Heart Failure (can be caused by eating incompatible medicine)
Blood Loss (injuries)
Dehydration
Starvation
Zara is talking to your outside game world via events (you can subscribe and listen to them from anywhere).
Zara will not eat your game performance: it is re-evaluating health state and all needed internals only once a second (you can customize this to be any number).
Zara is aware of the game surroundings if provided (air temperature, wind speed, rain intensity, time of day), and will adjust its parameters dynamically (in a hot day water will drain faster; in rainy cold day it is more likely to get flu, and so on.)
