Class RotatingGizmo

java.lang.Object
  gizmoball.board.Gizmo
      gizmoball.board.RotatingGizmo

public class RotatingGizmo
extends Gizmo

This class represents a rotating gizmo, such as a flipper, that extends the abstract Gizmo class. A rotating gizmo has an angular velocity, a range of angles in which it can rotate, a center of rotation, and an enclosing polygon which represents the polygon that the flipper occupies at different times during its rotation.

Constructs a RotatingGizmo object

Parameters:

name - the name of the gizmo

color - the color of the gizmo

shape - the shape of the gizmo

rotatingVel - the rotating velocity

enclosingPoly - the enclosing shape of the gizmo

centerOfRotation - the center of rotation

maxAngle - the maximus angle that the RotatingGizmo can rotate by

Method Detail

timeToNextStop

public double timeToNextStop()

The expected time until the gizmo will stop again. If it is not moving, inifinity is returned.

Returns:

the time until the gizmo will stop again

getEnclosingPolygon

public Polygon getEnclosingPolygon()

returns the enclosing polygon of the gizmo

Returns:

the enclosing polygon

getAngularVelocity

public double getAngularVelocity()

returns the current angular velocity.

Returns:

the current angular velocity

getCurrentAngle

public Angle getCurrentAngle()

returns the current angle that the rotating gizmo is at.

Returns:

the current angle

getMaxAngle

public Angle getMaxAngle()

returns the max angle that the gizmo can be rotated by.

Returns:

the max angle

getCenterOfRotation

public Vect getCenterOfRotation()

returns the center of rotation of the gizmo.

Returns:

the center of rotation

rotateAroundCenter

public void rotateAroundCenter(double dt)

rotates the gizmo around its center of rotation.

Parameters:

dt - how long the rotating gizmo is rotated for

action

public void action()

executes the action of the rotating gizmo which changes the mode of the flipper from stationary to rotating and vice versa.

Overrides:

action in class Gizmo
