    <p>In a game that I'm working on I have implemented some powerups. I want the powerups to spawn at the same place as the zombie that you killed died on. </p> <p>I spawn all the zombies with a <code>ArrayList</code> so therefor when I kill a zombie I have to spawn the powerup at that zombies location and not any other zombies location. I got this code in a <code>paintComponent(Graphics g)</code> method (zombies is the <code>ArrayList</code>).</p> <pre><code>for(int i = 0; i &lt; zombies.size(); i++){ Zombie z = (Zombie) zombies.get(i); if(!z.isAlive()){ ImageIcon ii = new ImageIcon("Health.png"); image = ii.getImage(); g2D.drawImage(image, (int) z.getX(), (int) z.getY(), this); System.out.println("Zombie state: " + z.isAlive()); } } </code></pre> <p>The problem is that when I kill a zombie it wont spawn the health pack at that zombies location (It wont spawn it at any other zombies location either). If I remove the <code>!</code> in the if-statement a health pack will be drawn inside all of the zombies so I know that it should spawn the health pack at the right location. </p> <p>It only print out the text "Zombie state: false" once so it have something to do with when it checks if the zombie is alive or not (probably that it only counts as <code>z.isAlive</code> is false when all zombies are dead). </p> <p><code>isAlive</code> in <code>Zombie</code> is only a boolean that equals to true as default and I have set it to equal false if you shoot a zombie with this if-statement. How would I check each zombie if it's alive (which I was pretty sure that I already had done because when one zombies health equals to 50 only that zombie dies and not all of them)?</p> <pre><code>if(z.getHealth() == 50) z.setAlive(false); </code></pre>

    1. COUnrelated to your actual questions, but if you use `ArrayList<Zombie>` you can avoid the dangerous cast and use `Zombie z = zombies.get(i);`.

    2. COShouldn't `Zombie.isAlive` always return false? I mean, they're all dead...

    3. COAs a basic piece of pattern advice, I'd recommend the use of either an `iterator` or an enhanced for loop here. Also, why do you have to cast back to `Zombie` after the get out of the `ArrayList`? Is it an `ArrayList<SomeSuperClazz>`?

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.
