Element Glider

JXG.GeometryElement,JXG.CoordsElement
   ↳ JXG.Point
         ↳ Glider

This element is used to provide a constructor for a glider point.

Defined in: point.js.
Extends JXG.Point.

Element Detail
Glider
A glider is a point which lives on another geometric element like a line, circle, curve, turtle.
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "glider".

Possible parent array combinations are:
{Number} z   Optional
{Number} x   Optional
{Number} y   Optional
{JXG.GeometryElement} GlideObject

Parent elements can be two or three elements of type number and the object the glider lives on. The coordinates are completely optional. If not given the origin is used. If you provide two numbers for coordinates they will be interpreted as affine euclidean coordinates, otherwise they will be interpreted as homogeneous coordinates. In any case the point will be projected on the glide object.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create a glider with user defined coordinates. If the coordinates are not on
// the circle (like in this case) the point will be projected onto the circle.
var p1 = board.create('point', [2.0, 2.0]);
var c1 = board.create('circle', [p1, 2.0]);
var p2 = board.create('glider', [2.0, 1.5, c1]);

				
				
// Create a glider with default coordinates (1,0,0). Same premises as above.
var p1 = board.create('point', [2.0, 2.0]);
var c1 = board.create('circle', [p1, 2.0]);
var p2 = board.create('glider', [c1]);

				
                
Field Detail
{JXG.GeometryElement} slideObject
When used as a glider this member stores the object, where to glide on. To set the object to glide on use the method JXG.Point#makeGlider and DO NOT set this property directly as it will break the dependency tree.
Defined in: coordselement.js.
Method Detail
startAnimation(direction, stepCount)
Animate the point.
Defined in: coordselement.js.
Parameters:
{Number} direction
The direction the glider is animated. Can be +1 or -1.
{Number} stepCount
The number of steps.
See:
Glider#stopAnimation

stopAnimation()
Stop animation.
Defined in: coordselement.js.
See:
Glider#startAnimation
