public class Light

extends SimulationParticipant

A Light is a simulation participant that basically sits still and produces a constant light (much as you would expect). Its screen representation is that of a small colored circle, just as a light bulb might appear from the top. When the light is broken by a vehicle that gets too close, the light goes out.

Light(double, double, Color)

Return a light at location (x,y) which produces c colored light.

display(Graphics)

Tell the Light to display itself using the given Graphics.

displayBroken(Graphics)

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

getDescription()

Return a string describing this light.

hasPointLocation()

Answer true to indicate that this light does in fact have a location.

step()

Perform light-specific simulation tasks

 public Light(double x,
              double y,
              Color c)

Return a light at location (x,y) which produces c colored light. The light must still be registered with the scenario in order to participate in the simulation.

Parameters:

x - double

y - double

c - java.awt.Color
