Class Animation2D

java.lang.Object
  java.awt.Component
      java.awt.Canvas
          Animation2D

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class Animation2D
extends java.awt.Canvas

Animation2D uses classes developed in last week's Transform2DTest project to confirm the applicability of Matrix-defined transformations to simple animations. Note: Add Path to Transform2DTest folder in Classes Tab of your JDK Profile. The Space Invaders Tutorial at http://www.planetalia.com/cursos/Java-Invaders/JAVA-INVADERS-11.tutorial was useful.

Field Detail

WIDTH

public static final int WIDTH

Constant Field Values

SPEED

public static final int SPEED

SPEED controls the delay of the utility Thread

See Also:

Constant Field Values

strategy

public java.awt.image.BufferStrategy strategy

Specialized class to support double buffering

maxX

public static double maxX

Cartesian parameters: domain, range, minX, maxX, minY, maxY

minX

public static double minX

maxY

public static double maxY

minY

public static double minY

domain

public static double domain

assists in converting cartesian coordinates to screen coordinates

range

public static double range

assists in converting Cartesian coordinates to Screen coordinates

sprite

public static Sprite sprite

an instance of the Sprite class to be animated

Constructor Detail

Animation2D

public Animation2D()

Single constructor (supplied)

Method Detail

updateScene

public void updateScene()

updateScene prepares and applies the matrix transform(s) to the Sprite object

scrX

public int scrX(double x)

Converts Cartesian x-coordinate to relative Screen x-coordinate

scrY

public int scrY(double y)

Converts Cartesian y-coordinate to relative Screen y-coordinate

paintPanel

public void paintPanel()

Creates a BufferedImage object, obtains its Graphics2D drawing context, and goes to work drawing to the image. Calls sprite's getData() method to obtain the set of points (vertices) transformed, drawn and connected. Hint. Consider copying the points to a java.awt.Polygon shape, and using the drawPoly(poly) method. Once rendered, obtain the visible drawing context from the strategy object, copying the BufferedImage to the visible canvas with the drawImage() method. Finally, strategy.show().

run

public void run()

Sequencer to organize calls and prove an animation speed.

main

public static void main(java.lang.String[] args)

Instantiates an animation object,a sprite with some meaningful set of points and then calls the run method.
