                 int v,
                 int i,
                 long s)

Initialize a ObstacleSim object. This is called automatically by JavaBotSim.

Overrides:

init in class ObstacleSim

Parameters:

xp - the x coordinate.

yp - the y coordinate.

t - ingored.

r - the radius.

f - the foreground color.

b - ignored.

v - the vision class.

i - the unique id.

s - random number seed.

getPosition

public Vec2 getPosition()

Description copied from interface: SimulatedObject

Find the center point of the object in absolute coordinates.

Overrides:

getPosition in class ObstacleSim

Tags copied from interface: SimulatedObject

Returns:

the point.

takeStep

public void takeStep(long time_increment,
                     SimulatedObject[] all_objs)

Take a simulated step;

Overrides:

takeStep in class ObstacleSim

Tags copied from interface: SimulatedObject

Parameters:

time_increment - how much time has elapsed since the last call.

all_objects - the other objects in the simulation.

draw

public void draw(java.awt.Graphics g,
                 int w,
                 int h,
                 double t,
                 double b,
                 double l,
                 double r)

Draw the object.

Overrides:

draw in class ObstacleSim

Tags copied from interface: SimulatedObject

Parameters:

g - graphics area to draw the object.

w - the width in pixels of g.

h - the height in pixels of g.

t - the y coordinate represented by the top boundary of the drawing area.

b - the y coordinate represented by the bottom boundary of the drawing area.

l - the x coordinate represented by the left boundary of the drawing area.

r - the x coordinate represented by the right boundary of the drawing area.

getClosestPoint

Description copied from interface: SimulatedObject

Find the closest point on the object from a particular location. This is useful for obstacle avoidance and so on.

Overrides:

getClosestPoint in class ObstacleSim

Tags copied from interface: SimulatedObject

Parameters:

from - the place from which the point is determined.

Returns:

the closest point.

getCenter
