Constructor Detail

DefaultTurtleShape

public DefaultTurtleShape()

Constructs the basic turtle shape (triangle).

DefaultTurtleShape

public DefaultTurtleShape(int size)

Constructs the basic turtle shape (triangle) with defined length of the side.

Parameters:

size - the length of the triangle side

Method Detail

paintTurtle

public void paintTurtle(Turtle t,
                        Graphics2D g)

Description copied from interface: TurtleShape

Paints the turtle shape.

Specified by:

paintTurtle in interface TurtleShape

Parameters:

t - the turtle whose shape is paint

g - the graphics where the turtle's shape should be paint

getViewCount

public int getViewCount()

Description copied from interface: TurtleShape

Returns immutable number of views provided by the shape. A shape can provided more views on the shape, e.g. depending on current direction of the turtle. Each shape must define at least one view.

Specified by:

getViewCount in interface TurtleShape

Returns:

the number of views on the shape

getFrameCount

public int getFrameCount()

Description copied from interface: TurtleShape

Returns immutable number of animation frames defined for each view of the shape. A view on a shape can consist of several frames. They are used to animate shapes. All views have the same number of frames. Each view must provide at least one animation frame.

Specified by:

getFrameCount in interface TurtleShape

Returns:

the number of animation frames

isPointOfShape

public boolean isPointOfShape(Turtle t,
                              double x,
                              double y)

Description copied from interface: TurtleShape

Returns whether a given point is internal point of current turtle's shape.

Specified by:

isPointOfShape in interface TurtleShape

Parameters:

t - the turtle whose shape is considered

x - the x coordinate of point

y - the y coordinate of point

Returns:

true, if the point [x, y] is an internal point of turtle's shape, false otherwise

getFrameDuration

public long getFrameDuration()

Description copied from interface: TurtleShape

Returns immutable animation delay (time period between animation frames) in milliseconds.

Specified by:

getFrameDuration in interface TurtleShape

Returns:

preferred animation delay in milliseconds

getSize

public int getSize()

Returns the size of the shape.

Returns:

the size of the shape
