I have a function that draws a stack of rounded rectangles ("disks") in a particular column. As the stack increases the disk size decreases.

I would like to be able to move these shapes between different columns. This is done buy the user clicking on a "disk" then clicking on a destination column. (I have already written a method that will get the first and second click co-ordinates, and draw something on the second click)

when the "move" occurs I need that particular disk to maintain its properties (i.e. Length).
I would like to somehow store each disk as it is made with an ID, so that later on I can draw a specific disk by refering to the ID.

i.e: (in this case the values don't matter, just the fact that they are different)

Code:

disks[0] = fillRoundRect(1,1,1,1,1,1)
disks[1] = fillRoundRect(2,2,2,2,2,2)
disks[2] = fillRoundRect(3,3,3,3,3,3)
disks[3] = fillRoundRect(4,4,4,4,4,4)
disks[4] = fillRoundRect(15,12,14,16,45)
disks[5] = fillRoundRect(n, n, n, n, n)

Is this possible?
Below is the code that I have been writing to accomplish this.

Code:

 public void drawDisk(int diskAmount, Graphics gfx){
        
        //set the color of the disks
        gfx.setColor(Color.ORANGE);
        
        int numberOfDisks = diskAmount;
        int i = 0;
        int row = 0;
        int col = 0;
        int startX = 7;
        int startY = 282;
        int endX = GAME_CELL_WIDTH - 4;
        int endY = DISK_HEIGHT - 4;
        
        //calculate the starting position of the cell
        int x = startX + col * GAME_CELL_WIDTH;

        //create the number of disks requested
        while (numberOfDisks > i){
             int y = startY - row * DISK_HEIGHT;       
            
            //create a new instance of disk
            Disk newDisk;
            newDisk = new Disk(row, 0, x, y, endX, endY);
            
            //decreases the disk of the next disk by moving the 
            //x and y.  Note the height stays the same
            x = x + 8;
            y = y + 8;
            endX = endX - 16;

            
            //not necessary in this loop, just here for testing
            int ax = newDisk.getStartX();
            int ay = newDisk.getStartY();
            int dx = newDisk.getEndX();
            int dy = newDisk.getEndY();
            
            //draw the "disk"
            gfx.fillRoundRect(ax, ay, dx, dy, 15, 15);

            //add the disk to an array
            this.addDisk(newDisk, i);
            
            //move to the next row
            row++;
            
            i++;
        }
    }

This little piece will add the disks to an array

Code:

 public void addDisk(Disk newDisk,  int diskId){
        
        int row = newDisk.getRow();
        int col = newDisk.getCol();

        //add the Disk to the Array
        this.disks[diskId] = newDisk;
        //change the value of the cell
        this.gameCells[row][col] = diskId;
        
    }

here is the code for my disk Class

Code:

public class Disk {
    
private int row;
private int col;
private int diskSize;
private int startX;
private int startY;
private int endX;
private int endY;
    
    /** Creates a new instance of Disk */
    public Disk(int row, int col, int x, int y, int dx, int dy) {
        this.row = row;
        this.col = col;
        //this.diskSize = size;
        this.startX = x;
        this.startY = y;
        this.endX = dx;
        this.endY = dy;
    }
    
    public int getRow(){
        return this.row;
    }
    
    public int getCol(){
        return this.col;
    }
    

    
    public int getStartX(){
        return this.startX;
    }
    
    public int getStartY(){
        return this.startY;
    }
    
    public int getEndX(){
        return this.endX;
    }
    
    public int getEndY(){
        return this.endY;
    }

}

I am trying to create a method called "moveDisk" that will, for example, delete disk[2] from the first clicked col, and redraw disk[2] in the second clicked column. I have been stuck on this for some time now and am going postal...

Code:

public void moveDisk(){
//no idea
}

Any suggestions?
Thanks.
