    <p>Im currently am working on a game in Java that spawns blocks on the top of the screen and they fall down (you have to dodge them). Currently I have the game spawning blocks on the top of the screen from an array but I do not know how to make their y position go down by (int).</p> <p>Basically I just need help making a public void that checks an object array and with every instance of a object it finds it drops the y position of it by 12. </p> <p>Selected snippits from code:</p> <pre><code>static Object[][] food = new Object[7][700]; public void draw() { try { Graphics g = bufferStrategy.getDrawGraphics(); g.clearRect(0, 0, this.getSize().width, this.getSize().height); // Draw to back buffer g.setColor(Color.WHITE); g.fillRect(0, 0, this.getSize().width, this.getSize().height); g.setColor(Color.BLUE); g.fillRect(Player.getX(), Player.getY(), Player.WIDTH, Player.HEIGHT); g.setColor(Color.GRAY); for(int x = 0; x &lt; food.length; x++) { for(int y = 0; y &lt; food[x].length; y ++) { Object o = food[x][y]; if(o instanceof Hamburger) { new Hamburger(x * 100, y, g); } else if(o instanceof Salad) { new Salad(x * 100, y, g); } } } GUI.draw(g); } catch(Exception e) { e.printStackTrace(); } finally { bufferGraphics.dispose(); } } public void dropBlocks() { } public void addBlock() { if(new Random().nextInt(2) == 1) { food[new Random().nextInt(7)][0] = new Hamburger(0, 0); } else food[new Random().nextInt(7)][0] = new Salad(0, 0); } public void drawBackbufferToScreen() { bufferStrategy.show(); Toolkit.getDefaultToolkit().sync(); } public void run() { int i = 0; while(running) { i++; draw(); Player.update(); drawBackbufferToScreen(); if(i == 50) { addBlock(); i = 0; } dropBlocks(); Thread.currentThread(); try { Thread.sleep(10); } catch(Exception e) { e.printStackTrace(); } } } </code></pre> <p>Food.java (What Hamburger and Salad extend)</p> <pre><code>public class Food { public static int x; public static int y; public static int HEIGHT; public static int WIDTH; public int type; private static Image blockImage; // Default constructor public Food() { Food.x = 0; Food.y = 0; Food.HEIGHT = 80; Food.WIDTH = 80; } public Food(int x, int y) { Food.x = x; Food.y = y; Food.HEIGHT = 80; Food.WIDTH = 80; } // Getters and setters </code></pre>

    1. CO`(which I dont think you do` -> No we do. We always do need code to understand what you are doing. So, please post a Short Compilable but Complete code that explains what you are doing.

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.
