Constructor Detail

SquareShape

public SquareShape(Window w)

Creates a new SquareGraphic instance.

Method Detail

setOrientation

public void setOrientation(Degree degree)

Sets the orientation (degree of rotation) of the shape

Parameters:

degree - The degree to which the orientation of the shape should be set.

getOrientation

public Degree getOrientation()

Gets the orientation (degree of rotation) of the shape

Returns:

The current degree of orientation.

update

public void update()

Update the position and orientation of the fish based on the velocity. If the fish hits a wall, it reverses velocity in the appropriate direction and points in the appropriate direction too.

Specified by:

update in interface IUpdatable

getVector

public Vector getVector()

Get the vector that controls the movement for this shape.

Returns:

The current movement vector.

setVector

public void setVector(Vector v)

Change the vector that controls the movement for this shape.

Parameters:

v - The new vector.

getDx

public java.lang.Integer getDx()

Get the x component of the movement vector (the change in x).

Returns:

The x component.

getDy

public java.lang.Integer getDy()

Get the y component of the movement vector (the change in y).

Returns:

The y component.

update

public void update(java.util.Observable o,
                   java.lang.Object arg)

Specified by:

update in interface java.util.Observer

Parameters:

o -

arg -
