    <p>I am making my own version of mario. One problem im running into is how to do the side scrolling part of the game. But i dont quite know how to implement the imageableX and imageableY into the world display. Any help would be much appreciated! Here is what i have so far:</p> <pre><code>public class World extends JPanel implements Runnable, KeyListener{ private static final int BEGINNING_X = 0, ENDING_X = 10000; private static final int TOP_Y = 0, BOTTOM_Y = 5000; private boolean inGame = false; private Player player; //set up a new world with a player public World(Player player){ inGame = true; this.player = player; } @Override public void paintComponent(Graphics g){ super.paintComponent(g); //the world size g.drawRect(0, 0, BEGINNING_X, ENDING_X); } //check to see if the new x postition is valid on the game board public boolean isValidXPosition(double x){ if(x &lt; BEGINNING_X || x &gt; ENDING_X){ return false; } return true; } public double imageableStartX(Player player){ if(player.returnX() - 100 &lt;= BEGINNING_X) return BEGINNING_X; else return player.returnX() - 100; } public double imageableTopY(Player player){ if(player.returnY()-100 &lt;= BOTTOM_Y) return BOTTOM_Y; else return BOTTOM_Y - 100; } public double imageableEndX(Player player){ if(player.returnX() + 200 &lt;= ENDING_X) return ENDING_X; else return player.getX() + 200; } public double imageableBottomY(Player player){ if(player.returnY()+100 &gt;= BOTTOM_Y) return BOTTOM_Y; else return BOTTOM_Y + 100; } public void run() { while(inGame){ //TODO run game code } } public void keyTyped(KeyEvent e) {} public void keyPressed(KeyEvent e) { if(e.getKeyCode() == KeyEvent.VK_RIGHT){ player.moveRight(); } if(e.getKeyCode() == KeyEvent.VK_LEFT){ player.moveLeft(); } if(e.getKeyCode() == KeyEvent.VK_SPACE){ player.setSprint(true); } if(e.getKeyCode() == KeyEvent.VK_UP){ player.Jump(); } } public void keyReleased(KeyEvent e) { if(e.getKeyCode() == KeyEvent.VK_UP){ player.Descend(); player.setFalling(true); } if(e.getKeyCode() == KeyEvent.VK_SPACE){ player.setSprint(false); } } } </code></pre>

    1. COYou might consider using a 2D tile engine to handle the drawing http://stackoverflow.com/questions/903760/java-2d-game-engine-for-tile-based-game

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
