public class Pulsar

extends Light

A Pulsar is a special kind of Light that changes in brightness over time. Its screen representation is that of a small colored circle whose radius varies between the radius of a normal Light when the Pulsar's brightness is at its peak and 0 (zero) when the Pulsar is at its dimmest. In addition to all of the properties inherited from Light, Pulsars have an additional property, a double period, which is the number of simulation steps required for the Pulsar's brightness to change from peak to peak.

Pulsar(double, double, double, Color)

Return a Pulsar at location (x,y) which produces c colored light and whose brightness will vary for a period of length p steps.

display(Graphics)

Tell the pulsar to display itself using the given Graphics.

displayBoken(Graphics)

Tell the pulsar to display itself as being broken using the given Graphics.

getDescription()

Return a string describing this pulsar.

getVariableBrightness()

Return the current brightness based on phase and period.

step()

Increment the number of steps that have passed and use that number to calculate the new brightness.

 public Pulsar(double x,
               double y,
               double p,
               Color c)

Return a Pulsar at location (x,y) which produces c colored light and whose brightness will vary for a period of length p steps. The Pulsar must still be registered with the scenario in order to participate in the simulation.

Parameters:

x - double

y - double

p - double

c - Color

 public void display(Graphics g)

Tell the pulsar to display itself using the given Graphics.

Parameters:

c - java.awt.Graphics

Overrides:

display in class Light

 public void displayBoken(Graphics g)

Tell the pulsar to display itself as being broken using the given Graphics.

Parameters:

c - java.awt.Graphics

 public String getDescription()

Return a string describing this pulsar.

Returns:

java.lang.String

Overrides:

getDescription in class Light

 public double getVariableBrightness()

Return the current brightness based on phase and period.

 public void step()

Increment the number of steps that have passed and use that number to calculate the new brightness.

Overrides:

step in class Light
