Interface TurtleShape

All Known Implementing Classes:

DefaultTurtleShape, ImageShape, ImageTurtleShape

public interface TurtleShape

The interface for painters of turtles' shapes.

Method Summary

Modifier and Type	Method and Description
int	getFrameCount() Returns immutable number of animation frames defined for each view of the shape.
long	getFrameDuration() Returns immutable animation delay (time period between animation frames) in milliseconds.
int	getViewCount() Returns immutable number of views provided by the shape.
boolean	isPointOfShape(Turtle t, double x, double y) Returns whether a given point is internal point of current turtle's shape.
void	paintTurtle(Turtle t, Graphics2D g) Paints the turtle shape.

Method Detail

paintTurtle

void paintTurtle(Turtle t,
                 Graphics2D g)

Paints the turtle shape.

Parameters:

t - the turtle whose shape is paint

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

getViewCount

int getViewCount()

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.

Returns:

the number of views on the shape

getFrameCount

int getFrameCount()

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.

Returns:

the number of animation frames

getFrameDuration

long getFrameDuration()

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

Returns:

preferred animation delay in milliseconds

isPointOfShape

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

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

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
