Private colorColor when rope is slack; a CSS3 color value
Private colorColor when rope is tight; a CSS3 color value
Private thickness_Thickness of lines when drawing the rope, in screen coordinates, so a value of 1 means a 1 pixel thick line.
Static Readonly paththe fixed length of the un-transformed path
Static Readonly paththe fixed width of the un-transformed path
Whether the DisplayObject contains the given world coordinates point.

true if this DisplayObject contains the given point
Draws this DisplayObject using the given CoordMap.

Returns the set of MassObjects that this DisplayObject represents. Returns an empty list if this DisplayObject doesn't represent a MassObject.

Sets this DisplayObject's position in simulation coordinates of the containing SimView. Each type of DisplayObject has a different policy regarding whether this will have an effect. Generally the policies are:
If the DisplayObject does not represent a SimObject, then the position can be set. Examples are DisplayClock, EnergyBarGraph.
If the SimObject's position is dependent on other objects, then the position cannot be set. Examples are DisplayConnector, DisplayRope, DisplaySpring.
If the SimObject can be moved independently and isDragable
is true, then the position of the SimObject is modified. Example: DisplayShape.
this DisplayObject's position, in simulation coordinates.
Thickness to use when drawing the line, in screen coordinates, so a unit is a screen pixel.

Returns a minimal string representation of this object, usually giving just identity information like the class name and name of the object.
For an object whose main purpose is to represent another Printable object, it is
recommended to include the result of calling toStringShort on that other object.
For example, calling toStringShort() on a DisplayShape might return something like
this:
DisplayShape{polygon:Polygon{'chain3'}}
a minimal string representation of this object.
Static Private drawDraws the rope using the given AffineTransform, which specifies the combination of translating, stretching, rotating the rope to its current position, and also the sim-to-screen transform. The path is drawn into a size of 6.0 long by 0.5 wide, so that when it is scaled up or down, it doesn't get too distorted. *

Generated using TypeDoc
Displays a Rope by showing a straight line when the Rope is tight, or a jagged line when the Rope has slack. Can have a different color when tight or slack, see setColorTight and setColorSlack.
The position is reported as the midpoint of the Rope by getPosition. The position is determined by the position of the Rope, so setPosition has no effect, and the DisplayRope is never dragable.
