<p>What i'm wondering is how to handle the creation of new units in the game (ie. making marines from the barrack). How would i store these units?</p>
<p>I was thinking of having a class 'unit' which would then be inherited by specific unit types (ie. marines, firebats, etc) but if i create an array for these (ie. Marines myMarines[20]) that will create a hard cap on these units.</p>
<p>How do i create such an array that can be expanded at will?
Thank you!</p>

113,056 | 113,057 | Weird Issue with the info/second View on iPod | <p>I just started testing my App on my iPod, and I have to click numerous times the info light button which is attached to my second view to show. I have to click it probably 10-15 times, then it finally triggers the second view to show. Of course in Simulator it works fine, but on the iPod it's rather weird that I have to keep hitting it to finally work. Then, sometimes it works without trying to hit it a ton of times. It's rather buggy. Curious if my code is crappy or what other issues are making this feature act weird.</p>
<p>Here is my code</p>
<pre><code>-(IBAction)infoButtonPressed:(id)sender

I went through lot of documents and articles but still I dint get why we should not reduce the visibility.</p>
<p>I have the following code </p>
<pre><code>class parent{
public void func()
{
System.out.println("in Parent");

}
public class TestClass extends parent {
public static void main(String args[])
{

obj.addTest();
}
private void func()
{
System.out.println("in child");
}
}
</code></pre>
<p>Here parent class has <code>func()</code> method which is public and overridden by the subclass <code>TestClass</code> which is private. Now the compiler throws the error that I cannot the reduce the visibility. To say technically, whenever I create a object of <code>TestClass</code> assigning to the type parent object, since the <code>func()</code> method is overridden, TestClass's func() is going to get called always, then why we should take care of visibility? whats the reason behind this error ? Can someone please explain me clearly ?</p>

I have chosen not to use the default_timezone_set function because I am afraid that this changes the time on a global level and that if another request somewhere else is occurring within my app, that the wrong time will be used; that is, the time that is being calculated at that moment using the default_timezone_set function.</p>

ALL GREAT COMMENTS - THANK YOU</p>

I know I can use ":not" to add exclussion rules when referencing a group of items, but that is not the same question, since I want to know if it is possible to substract a group of elements from a different group of elements already referenced.</p>
<p>¿why is that? because imagine the first group is created according to a set of dynamic rules and some elements could have been added or removed, and when I want to substract the second set of elements from the first group, I dont really know which elements are in the first group. That is, there is no such rule that can be applied using selectors to obtain what I am looking for.</p>
<p>The idea is something like this:</p>
