Java games rock!

« Posted 2004-11-02 00:08:15 »

Hi there,

I'm doing a program that shows both points and text in a colored-spiral:

Now I'm trying to get letters/text to alternate with the points  in the spiral. Problem is how do I set this up? How do I get text to go into the spiral along with the points?

Here is the code, just copy and paste, then run to see how it works. Certain code I commented out in regards to using "String" and "text" and it wasn't really working.

Any suggestions are great. PLEASE!!!


import java.awt.*;

import java.awt.event.*;



//Color-Blended Five-Sided Polygon Program
public class Color


 public static void main(String[] args)


   Frame frame = new Frame("Spiral");

   GLCanvas canvas = GLDrawableFactory.getFactory().createGLCanvas(new GLCapabilities());

   canvas.addGLEventListener(new Renderer());


   frame.setSize(400, 300);


   frame.addWindowListener(new WindowAdapter()


     public void windowClosing(WindowEvent e)










 static class Renderer implements GLEventListener, KeyListener



public void display(GLDrawable gLDrawable)


    final GL gl = gLDrawable.getGL();

    final GLU glu = gLDrawable.getGLU();
    // final GLUT glut = new GLUT();



    float [][] CLUT ={{1.0f,0.0f,0.0f},{1.0f,0.5f,0.0f},{1.0f,1.0f,0.0f},


           {0.5f,0.0f,0.5f}, {1.0f,0.0f,0.5f}};
    // String [] fonts = { "T", "B","R", "P","H","F"};


     gl.glClear (GL.GL_COLOR_BUFFER_BIT);  // Set display window to color.

       gl.glMatrixMode (GL.GL_MODELVIEW);



     double x = 0.0, y = 0.0, r=0.0, rad,ang=0.0;

     float point = 0.1f;
    //float text1 = 0.1f;
    //float text2 = 0.1f;

     rad =(Math.PI/180.0);


        for (int i=0; i<80; i++){


          // gl.glRasterPos2d(x,y); // set position
           //glut.glutBitmapString(gl, i+2, fonts[i%8]);


           x = r*Math.cos(rad*ang);

           y = r*Math.sin(rad*ang);








                 point += 0.3f;




public void init(GLDrawable gLDrawable)


     final GL gl = gLDrawable.getGL();

     final GLU glu = gLDrawable.getGLU();


     gl.glMatrixMode (GL.GL_PROJECTION);  

     gl.glClearColor (0.0f, 0.0f, 0.0f, 0.0f);   //set background to white

     glu.gluOrtho2D (-250.0, 250.0, -250, 250.0);  // define drawing area



    public void displayChanged(GLDrawable gLDrawable, boolean modeChanged, boolean deviceChanged)




      public void reshape(GLDrawable gLDrawable, int x, int y, int width, int height)





   public void keyPressed(KeyEvent e)


     if (e.getKeyCode() == KeyEvent.VK_ESCAPE)




   public void keyReleased(KeyEvent e) {}


   public void keyTyped(KeyEvent e) {}



Help! Again, any suggestions will be great! Thanks!
