I have a project in which i don't get.. I have been working on it for days.. we are supposed to make the thing move around the frame for a number of times( eg. 5), then it will move diagonally (certain # of times) then across and down the centre of the frame then around a circle in the middle.. pls help.. here is my code so far: import java.awt.*; import javax.swing.*; import java.awt.geom.AffineTransform; public class NAME extends JApplet implements Runnable{ private double currentAngle; int xRot; int yrot; int i=0; final int N=50; Image ImageBuffer=null; Graphics GraImage=null; int x=0; int y=0; //double angle; public void init(){ //setBackground(Color.white); } public void start() { Thread th=new Thread(this); //Thread starts th.start (); } //square rotation around the frame public void run() { //Thread Priority Thread.currentThread().setPriority(Threa? for(int countime=0;countime<4;countime++){ for( ;true;) { //1, right while(x<=900) { x++; repaint(); if(x==900) { x=900; currentAngle=90; } try { //Stop Thread Thread.sleep(1); } catch(InterruptedException ex) { //do nothing } } //2, bottom while(y<=650) { y++; repaint(); if(y==650) { y=700;//700 currentAngle=180; } try { //Stop Thread Thread.sleep(1); } catch(InterruptedException ex) { //do nothing } } //3 ( left) while(x>=50) { x--; if(x==50)//50 { x=0;//0 currentAngle=270; } repaint(); try { //Stop Thread Thread.sleep(1); } catch(InterruptedException ex) { //do nothing } } //4.. top while(y>=50) { x++; repaint(); if(y==50) { y=0; currentAngle=0; } try { //Stop Thread Thread.sleep(1); } catch(InterruptedException ex) { //do nothing } } } } while(x>=0) { x++; repaint(); try { //Stop Thread Thread.sleep(2); } catch (InterruptedException ex) { //do nothing } } } public void paintF(Graphics g) { // super.paintF(g); Dimension d = size(); Image image2=Toolkit.getDefaultToolkit().getIm? int w= image2.getWidth(this); int h = image2.getHeight(this); g.drawImage(image2,0,0,900,700, this); Graphics2D g2d = (Graphics2D) g; AffineTransform origXform = g2d.getTransform(); AffineTransform newXform = (AffineTransform) (origXform.clone()); /*int radius = 200; double angle = 2*Math.PI*i/(double)N; x = (int)( radius*Math.cos(angle) ); y = (int)( radius*Math.sin(angle) );*/ //xRot = this.getWidth()/2; //yRot = this.getHeight()/2; newXform.rotate(Math.toRadians(currentAn? y); g2d.setTransform(newXform); Image image=Toolkit.getDefaultToolkit().getIma? g2d.drawImage(image,x,y,null); }//end of action public void update(Graphics g){ ImageBuffer = createImage(this.getWidth(),this.getHeig? GraImage=ImageBuffer.getGraphics(); paintF(GraImage); GraImage.dispose(); g.drawImage(ImageBuffer,0,0,this); } public void paint(Graphics g){ update(g); } public static void main(String[] args){ JFrame f =new JFrame("Animation"); f.setDefaultCloseOperation(JFrame.EXIT_O? JApplet ap = new Underwater(); ap.init(); ap.start(); f.setSize(900,732); f.add("Center", ap); f.setLocation(65,0); f.setVisible(true); }} the background pic is underwater then the thing moving is a starfish |

Can you edit your post using syntax tags?

If you can't edit your original post, just make a new post with the code or syntax tags. And as RandomLetters has mentioned. we could do with a bit more problem specifics. What exactly are you stuck on? |
