Class GravityField

Extends JEffect.
GravityField a gravity field effect This effect has a radius within which it will either attract or repel bodies depending on the defined force (positive values attract, negative repel) and their distance (the closer the object, the stronger the effect). This effect will be applied continuously as long as it is enabled This effect can either be placed at an arbitrary location in the scene, or it can be attached to a parent object.
Defined in: gravityField.js.

GravityField(location, _radius, _force, _parent)

Author: Jim Sangwine.

Parameters:
{array} location: initial location of the effect expressed as a 3D vector

{number} _force: the force of the effect at 0 distance (impulse will be force/distance)
{RigidBody} _parent: optional - a RigidBody that the gravitational field will follow - excluded from effect

Requires:: Vector3DUtil
