<p>If the increment method alters the value of y, is the value of z also changed? In my book, when y is altered, z is also altered, but, how is that possible if z was already assigned to y before the increment method was called? Also I don't understand why x has anything assigned to it after the method. I thought that the scope of the method stays within the method; therefore after increment(y) exits, the value of x remains unchanged.</p>
<p>Please correct me if I am wrong because I am fairly new to programming.</p>

4,180,103 | 4,180,104 | Java real time strategy game development | <p>I'm coming to the end of my first year of CS and I thought a great way to consolidate all the things I've learnt this year would be a personal game project.</p>
<p>I would like to implement a 2D based rts, I'm thinking along the lines of starcraft I, warcraft II or even command and conquer. I will have about 3 months without interruptions to implement the game.</p>
<p>So to anyone experienced with java game programming, I have a few questions:</p>
<p>Is it realistic to design a 2D rts engine from scratch in 3 months?
If so what are some good books/resources to get started?</p>
<p>Would it be better to modify some existing project? I would think the experience of having to work with a lot of someone else's code would be good since our exposure to such topics in an undergrad cs degree seems very rare, if non-existent.</p>
<p>Are there any decent open source 2d rts projects that anyone could recommend? I've looked through a few but most seem to be written in c/c++</p>
<p>My humble thanks</p>
<p>Edit: Thanks for the quick responses, I think that perhaps it was a bad idea to post this in a rush since I think I misrepresented what I want to do. </p>
<p>When I say "along the lines of warcraft II etc" I mean more like that style of rts using sprites. I don't intend to implement a game nearly that complex, more like just a basic prototype. </p>
<p>My goal would be some thing more like a flat textured map with some basic obstacles like trees, a single unit producing structure like a barracks. I'd like to have the units to have health bars, be able to move and attack and die (and possible morph into another unit). </p>
<p>Far off goals would be to implement some basic pathing using a modified version of the dijkstra shortest path algorithm, ranged units with missle attack, etc.</p>
<p>I don't plan to implement any opponents or ai or networking or anything like that.</p>

<p>The first list displays Method Statements - when the user select a method statement the second list displays a list of Risk Assesments for this method statement. I have this all working with no issues.</p>
<p>I now need to extend this so that the user can select (via a checkbox) the Method Statements that they want to use.

I do however need the user to be able to manually check the item to include it.</p>

4,304,956 | 4,304,957 | Attach to Property's setter | <p>I haven't found similiar post so I'm asking this.<br>
Let's say I defined somewhere an application wide available static Property (I mean it's not local) and in one class I would like to know when this property is being changed. Apart from aop (transparentproxy etc.) which I think doesn't suit me well here (and I can't add that to project anyway), what are the options here? </p>
<p>One solution I can think of, which is probably a very nasty one, is to use some event that would be executed in the setter and just attach it in the class(es) which needs that.
Something like: </p>
<pre><code> public static event EventHandler CurrentNumberChanged= delegate {};
public static int CurrentNumber
{
get
{
return currentNumber;
}
set
{
currentNumber = value;
CurrentNumberChanged(null, EventArgs.Empty);
}
}
</code></pre>
<p>I know it's really unsafe to use such events ( <a href="http://stackoverflow.com/questions/289002/how-to-raise-custom-event-from-a-static-class/289358#289358">read here</a> ). And since I would use it in asp.net makes it even more ugly. Do you have any advices ?</p>

<p>What is the best way to import javascript file (file.js) in javascript function().</p>
<p>For example what is the best way to replace the todo statement:</p>
<pre><code>function doSomething() {
if (xy.doSomething == undefined) {
// todo: load 'oldVersionPatch.js'
}
...
}
</code></pre>
<p>Possibly the best solution is to create script element and add it into html page.
My questions are:</p>
<ul>
<li>is it better to add/append it into head, or body (what will load when)?</li>
<li>is it better to use javascript or jquery (what is more cross-browser compatible)?</li>

1,533,963 | 1,533,964 | how to create a new php page with php- apostrophe issue | <p>To be more clear, I do understand how to create a new php file with php, I'm using <code>fwrite</code>, like so:</p>
<pre><code>//actually create the file now
$my_file=$post_title_edited . ".php";;
$fh= fopen($my_file, 'w');
fwrite($fh, $head);
fwrite($fh, $body);
fwrite($fh, $php);
fwrite($fh, $php2);
fwrite($fh, $php3);
fwrite($fh, $phpend);
fwrite($fh, $end);
fclose($fh);
//redirect to created file
header("location:". $post_title_edited .".php");
</code></pre>
<p>Now it all works just fine, or rather it would, if it were not for this issue:</p>
<pre><code>$php3='
session_start();
if(isset($_SESSION['login'])){
$myusername = $_SESSION['login'];
echo ' <div id="header-logedin">
<h3>Hello ' . $myusername . '</h3>
<a href="login/logout.php">Log out</a>
</div><!--header-logedin-->
';
} else {
echo $log;
}
</code></pre>
<p>As you can see, when i begin to set <code>$php3</code>, it is interupted by the apostrophe in the login from my first session call. Therefore it can't be set and in turn i can't write it into my new file, also <code>$php2</code> has this same problem. </p>
<p>What am i trying to do? In a nutshell: user posts from index.php information posts over onto new page created by this code, after data is checked against sql table to make sure it doesn't already exist, very much like a forum. I really hope this is something complicated and I'm not overlooking something incredibly obvious. Thanks in advance.</p>

The POJO contains many String / boolean / int attributes, so I don't want to store them each individually. The problem I'm running into is that the only preference variable types are String, boolean, float, and int. Is there some way to convert the POJO to a String that I could then retrieve back per it's key and convert back to the POJO, sort of like casting it>
1) Populate the POJO
2) Convert the POJO to a String
3) Store the String in the preference Store with a key value (normal preference store stuff)
4) When needed, retrieve the data back from the preference store as a String and convert it back to the POJO. </p>

195,711 | 195,712 | Why doesn't Android API publicly allow to listen for incoming SMS? | <p>Recently a question here on SO ported this to my attention. Android doesn't have a public API for listening to incoming SMS. There used to be an action <code>android.provider.Telephony.SMS_RECEIVED</code>, but it has been removed from the official API and even if it still works, it's obviously not future-proof. I don't need this feature right now, but I may in the future, and I find it very strange it's not available because:</p>
<ol>
<li>Android has always encouraged the deep customization of every little part of the system (think of tha launcher, the dialer, the contact app)</li>
<li>There are plenty of alternatives to the standard SMS app already in the Market (not to mention the vendors' ones)</li>
</ol>
<p>Maybe I am missing something or maybe there's a technical reason - I admit not know how SMS works</p>
