## Description

Unity3d project for simulating simple orbits using 2-body solution model.

## Importing

This repository contains the entire Unity Project for basic demo setup.

There are several ways to import the project:

- Manually copy all files from Asset directory to your unity project directory;

- Import asset store package;

- Import of the 'src' branch as [embedded package](https://docs.unity3d.com/Manual/CustomPackages.html#EmbedMe).

## Usage

This plugin has the ability to customize orbits using the editor inspector and scripts.

Some scripting usage examples:

#### Initializing orbit from orbit elements (JPL database supported)

```cs

	var body = GetComponent();

	body.AttractorSettings.AttractorObject = attractorTransform;

	body.AttractorSettings.AttractorMass = attractorMass;

	body.AttractorSettings.GravityConstant = GConstant;

	body.OrbitData = new KeplerOrbitData(

		eccentricity: eValue,

		semiMajorAxis: aValue,

		meanAnomalyDeg: mValue,

		inclinationDeg: inValue,

		argOfPerifocus: wValue,

		ascendingNodeDeg: omValue,

		attractorMass: attractorMass,

		gConst: GConstant);

	body.ForceUpdateViewFromInternalState();

```

#### Initializing orbit from orbit vectors

```cs

	var body = GetComponent();

	body.AttractorSettings.AttractorObject = attractorTransform;

	body.AttractorSettings.AttractorMass = attractorMass;

	body.AttractorSettings.GravityConstant = GConstant;

	body.OrbitData = new KeplerOrbitData(

		position: bodyPosition, 

		velocity: bodyVelocity, 

		attractorMass: attractorMass, 

		gConst: GConstant);

	body.ForceUpdateViewFromInternalState();

```
