  • I need to move an entity to the mouse location after i rightclick

    - by I.Hristov
    Well I've read the related questions-answers but still cant find a way to move my champion to the mouse position after a right-button mouse-click. I use this code at the top: float speed = (float)1/3; And this is in my void Update: //check if right mouse button is clicked if (mouse.RightButton == ButtonState.Released && previousButtonState == ButtonState.Pressed) { // gets the position of the mouse in mousePosition mousePosition = new Vector2(mouse.X, mouse.Y); //gets the current position of champion (the drawRectangle) currentChampionPosition = new Vector2(drawRectangle.X, drawRectangle.Y); // move champion to mouse position: //handles the case when the mouse position is really close to current position if (Math.Abs(currentChampionPosition.X - mousePosition.X) <= speed && Math.Abs(currentChampionPosition.Y - mousePosition.Y) <= speed) { drawRectangle.X = (int)mousePosition.X; drawRectangle.Y = (int)mousePosition.Y; } else if (currentChampionPosition != mousePosition) { drawRectangle.X += (int)((mousePosition.X - currentChampionPosition.X) * speed); drawRectangle.Y += (int)((mousePosition.Y - currentChampionPosition.Y) * speed); } } previousButtonState = mouse.RightButton; What that code does at the moment is on a click it brings the sprite 1/3 of the distance to the mouse but only once. How do I make it move consistently all the time? It seems I am not updating the sprite at all. EDIT I added the Vector2 as Nick said and with speed changed to 50 it should be OK. I tried it with if ButtonState.Pressed and it works while pressing the button. Thanks. However I wanted it to start moving when single mouse clicked. It should be moving until reaches the mousePosition. The Edit of Nick's post says to create another Vector2, But I already have the one called mousePosition. Not sure how to use another one. //gets a Vector2 direction to move *by Nick Wilson Vector2 direction = mousePosition - currentChampionPosition; //make the direction vector a unit vector direction.Normalize(); //multiply with speed (number of pixels) direction *= speed; // move champion to mouse position if (currentChampionPosition != mousePosition) { drawRectangle.X += (int)(direction.X); drawRectangle.Y += (int)(direction.Y); } } previousButtonState = mouse.RightButton;

  • Is there a real name policy in the Ubuntu community?

    - by martin001
    I'm not ashamed to be a part of Ubuntu, but I'm trying to keep the number of web search hits for my real name low, which is kinda impossible if you use a Launchpad account. So, I'm wondering if there is a real name policy in the Ubuntu community, or if it's okay to use a pseudonym/nick name/fake name? While it might be okay to use nick names on IRC and in forums, how about these topics: Adding an OpenPGP key to Launchpad. Signing the Ubuntu Code of Conduct. Becoming an Ubuntu member. Code contributions (e.g., signing the Canonical CLA). Thanks in advance for your answers!

  • Cyrus: In practical terms, how do end users administer their shared mailboxes?

    - by Nick
    Let's say we have four customer service reps: Billy, Bob, Joe, and Tom. Tom is the department manager. There's a shared Customer Service mailbox on the Cyrus server that they all have access to. Tom, as the manager also has administrative privileges for the shared mailbox. They decide they want to create sub-folders a certain way, and Tom creates them. They're all running Thunderbird, so Tom right-clicks the main folder and chooses "New Subfolder". Now Tom has the Subfolders he needs and the other sales reps have... nothing! Because Cyrus created the Subfolders giving Tom "Full Access" permissions, and everyone else gets no access. So how does Tom give the other reps in his department access to the new folders? As far as Cyrus is concerned, Tom has permission to grant others access to his new mailboxes- But as far as I can tell, there's no option in Thunderbird for granting mailbox permissions. An IT staff member should not have to receive a support request every time someone wants to add a Subfolder to a shared mailbox. That's why we make certain users into mailbox admins in the first place! But asking (non-technical) users to SSH into an IMAP server to run cyradm seems like a bad idea too. Certainly someone has found a solution for this dilemma. Perhaps a Thunderbird extension for setting Cyrus permissions? Or something like umask that forces subfolders to have identical permissions to their parents on creation? And related, what about Sieve configuration? Is there anyway that can be done from the client machine too? Thanks, Nick

  • Postfix / Dovecot email setup not storing email

    - by Nick Duffell
    I'm trying to setup postfix / dovecot on my debian server to use it for a mail server. I set everything up according to a tutorial on the net, and it all seemed OK. I can send emails from it, so SMTP is not a problem, however I cannot receive emails. Looking into the files in /home/nick/mail/ I can see that if I send an email to myself (from the server, to itself) the emails are there, but are put straight into the Deleted Messages folder. I don't know why this is. When I send an email from another mail account (not on this server), the emails are nowhere to be found. Also, looking at the log file /var/log/mail.log all seems to be OK, I get the following when I receive an email, which looks OK to me: Nov 7 22:47:22 nickduffell postfix/local[17825]: 05B1173581A6: to=, relay=local, delay=0.37, delays=0.31/0.02/0/0.03, dsn=2.0.0, status=sent (delivered to mailbox) Any ideas? Thanks EDIT: I should also add that although the emails I send myself are in the Deleted Messages folder, and in my mail client I can see that "Trash" has 3 items, I cannot download them in my mail client...

  • GlassFish v2.1 -- getting Application Client and Eclipselink to work together?

    - by Nick
    We are trying to use Eclipselink 1.1 with Glassfish v2.1. Following the instructions on: http://wiki.glassfish.java.net/Wiki.jsp?page=FaqEclipseLinkGlassFishV2 I adapted the instructions for the appclient script on linux by adding the lines: APPCPATH=$APPCPATH:$AS_INSTALL/lib/eclipselink-1.1.1.jar export APPCPATH to the appclient shell script. This however is not working. On running the application client (using Glassfish's webstart), I get the error: WARNING: "IOP00810257: (MARSHAL) Could not load class org.eclipse.persistence.indirection.IndirectList" Anyone else succeed in getting GF v 2.1 to work with eclipselink? or any ideas on what I might be doing wrong? I found this bug report: http s://glassfish.dev.java.net/issues/show_bug.cgi?id=8204 (New users can't post more than 1 link, so remove the space between 'http' and 's'.) Where Tim Quinn (tjquinn) said: App client container support for persistence is not yet in place I think this refers only to Glassfish v3, and it should be working in Glassfish v2. Is this correct? I'm working on the assumption that this will work once the ACC knows where to find the eclipselinks jar. Thanks in advance, Nick.

  • "Object reference not set to an instance of an object": why can't .NET show more details?

    - by Simon Chadwick
    "Object reference not set to an instance of an object" This is probably one of the most common run-time errors in .NET. Although the System.Exception has a stack trace, why does the exception not also show the name of the object reference field, or at least its type? Over the course of a year I spend hours sifting through stack traces (often in code I did not write), hoping there is a line number from a ".pdb" file, then finding the line in the code, and even then it is often not obvious which reference on the line was null. Having the name of the reference field would be very convenient. If System.ArgumentNullException instances can show the name of the method parameter ("Value cannot be null. Parameter name: value"), then surely System.NullReferenceException instances could include the name of the null field (or its containing collection).

  • What options to parse a DTD using PHP

    - by Chadwick
    I need to parse DTDs using PHP and am hoping there's a simple library to help out. Each DTD has numerous <!ENTITY... and <!-- Comment... elements, which I need to act upon. Note that I do not need to validate anything against these DTDs, simply parse them as data files themselves. A few options I've looked at: James Clarke's SD, which is an option of last resort, but I'd like to avoid the complexity of building/installing/configuring code external to PHP. I'm not sure it's even possible in my situation. PEAR has an XML_DTD_Parser, which requires installing/configuring PEAR and a number of pear modules, which I'm also not sure is possible, and would rather avoid. Has anyone used it with success? PHP XML Classes has the class_path_parser, which another site suggested, but it fails to read ENTITY elements. It appears to be using PHP's built in XML parsing capabilities, which use EXPAT. PHP's DOMDocument will validate against a DTD, so must be able to read them, though I don't see how to get at the DTD parser directly at first glance.

  • Visual Artifacts in Visual Studio 2010

    - by Simon Chadwick
    I'm using VS 2010 on Windows Server 2003, running on a Dell Inspiron 9400 laptop. VS 2010 runs fine, except for persistent and random screen re-drawing issues. Samples of these are here. These artifacts occur as the mouse moves over items that highlight on a mouse-over event, while scrolling, and when switching tabs. VS 2008 has non of these issues, so I assume that it is related to VS 2010's use of WPF. Could it be that my video card or driver is not up to the task of rendering WPF? Some other WPF applications (not Silverlight) also have some of these screen repainting problems. I have tried a variety of settings in System Properties--Advanced--Performance Options--Visual Effects, and in the related "Advanced" tab, Processor Scheduling is adjusted for best performance of programs. Many thanks for any suggestions!

  • Disable Eclipse warning about generated html?

    - by Chadwick
    When developing Flex projects, Eclipse gives warnings about the default index.html file generated by Flex Builder. The file is in the 'target' folder (or "generated artifacts" folder. Yes, I'm also using Maven). Can I eliminate or disable this warning? The code which generates the warning is below, though I would definitely prefer not changing the html - as I say this is the template suggested by Adobe. Eclipse warns of "Undefined attribute name (xxx)" for scroll on the body tag, and most of the embed attributes. There is no DOCTYPE declaration in the html file. <html lang="en"> ... <body scroll="no"> ... <embed src="myswf.swf" quality="high" bgcolor="#869ca7" width="100%" height="100%" name="myswf-flex" align="middle" play="true" loop="false" quality="high" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer"> </embed> ...

  • Does the box API require case-sensitive booleans?

    - by Nick Chadwick
    I'm having some issues with the box.com developer API, and it seems that this is due to the API requiring lower-case booleans in request parameters. When I make a call to say, delete a folder, the URI my framework is generating looks like this: (DELETE) https://api.box.com/2.0/folders/1234?recursive=True This doesn't work, and the API throws an error. However, if I manually set the URI to this: (DELETE) https://api.box.com/2.0/folders/1234?recursive=true Everything seems to work just fine. I'd like to confirm that this is indeed the behavior, and if it is, I'd like to request box fix their API!

  • Active User Tracking, PHP Sessions

    - by Nik
    Alright, I'm trying to work on a function for active user counting in an AJAX based application. I want to express the below SQL Query in correct syntax but I'm not sure how to write it. The desired SQL Query is below: SELECT count(*) FROM active WHERE timestamp > time() - 1800 AND nick=(a string that doesn't contain [AFK]) Now, I do understand that time() - 1800 can be assigned to a variable, but how is timestamp > variable and nick that doesn't contain a string written in SQL?

  • Understanding WebRequest

    - by Nai
    I found this snippet of code here that allows you to log into a website and get the response from the logged in page. However, I'm having trouble understanding all the part of the code. I've tried my best to fill in whatever I understand so far. Hope you guys can fill in the blanks for me. Thanks string nick = "mrbean"; string password = "12345"; //this is the query data that is getting posted by the website. //the query parameters 'nick' and 'password' must match the //name of the form you're trying to log into. you can find the input names //by using firebug and inspecting the text field string postData = "nick=" + nick + "&password=" + password; // this puts the postData in a byte Array with a specific encoding //Why must the data be in a byte array? byte[] data = Encoding.ASCII.GetBytes(postData); // this basically creates the login page of the site you want to log into WebRequest request = WebRequest.Create("http://www.mrbeanandme.com/login/"); // im guessing these parameters need to be set but i dont why? request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; // this opens a stream for writing the post variables. // im not sure what a stream class does. need to do some reading into this. Stream stream = request.GetRequestStream(); // you write the postData to the website and then close the connection? stream.Write(data, 0, data.Length); stream.Close(); // this receives the response after the log in WebResponse response = request.GetResponse(); stream = response.GetResponseStream(); // i guess you need a stream reader to read a stream?

  • WPF MediaPlayer doesn't play M4A?

    - by Nick
    I am trying to use a MediaPlayer instance to play M4A files. For those of you that aren't familiar, MediaPlayer is the non-XAML version of a MediaElement. There are pretty much the same, but I don't want any XAML, so I use a MediaPlayer instead. Anyways, it plays some M4A files just fine. The NaturalDuration of other M4A files is 0, but it still plays. The remaining files don't play at all and the exception thrown is "Media file download failed." Playing all these songs using Windows Media Player works perfectly. Isn't the MediaPlayer and MediaElement classes built upon the same framework as WMP? I'm confused as to why it isn't working. Any help is greatly appreciated. Thanks, Nick

  • onload Event in embedded SVG not calling function in attached script. Scope Issue?

    - by Nick
    Hi So I've got an XHTML page with a script - not inline > <script type="text/javascript" > src="../global/js/scripts.js"></script> and an embedded (I tried embed and object, same behavior) SVG document with a onload="CheckIfLoaded(evt)" attribute. The problem is firefox doesn't call the CheckIfLoaded() function in scripts.js. Firebug gives me "CheckIfLoaded() is not defined" with no reference to any line numbers. I can't find any information regarding the scope of javascript functions with respect to embedded content. Curiously, it works fine in IE. I could of course add a reference to the script into the SVG file as well but I believe that will result in the client downloading the scripts file twice and in addition I have 1000+ svg files and I'd really rather not add one line to all of them, although I suppose I could write a batch file or whatever if I have to. Any one know more about this? Thanks, Nick

  • How can I hide a database column in the entity model?

    - by Nick Butler
    Hi. I'm using the Entity Framework 4 and have a question: I have a password column in my database that I want to manage using custom SQL. So I don't want the model to know anything about it. I've tried deleting the property in the Mapping Details window, but then I got a compilation error: Error 3023: Problem in mapping fragments starting at line 1660:Column User.Password in table User must be mapped: It has no default value and is not nullable. So, I made the column nullable in the database and updated the model. Now I get this error: Error 3004: Problem in mapping fragments starting at line 1660:No mapping specified for properties User.Password, User.Salt in Set Users. An Entity with Key (PK) will not round-trip when: Entity is type [UserDirectoryModel.User] Any ideas please? Thanks, Nick

  • Why does installing NVidia 9600GT graphics card, take 1GB of RAM away from Windows?

    - by Nick G
    Hi, I've changed graphics cards in my PC and now Windows 7 (32bit) is reporting that I have a whole gigabyte less physical RAM in my PC. Why is this? Firstly, the machine has 4GB of physical RAM. The old card was an ATI 2600XT with 256MB and the new card is an NVidia 9600GT with 512MB. With the ATI card windows sees 3326MB. With the NVidia card, windows sees 2558MB. I realise that due to address space restrictions I will not see all 4GB with 32bit windows, but why is there such a massive loss of RAM when simply changing cards (bearing in mind BOTH cards have their own RAM and borrow no main memory like some built on chipsets do). Would using 64 bit windows solve this? Thanks Nick.
