• Perminantly Sync a wiimote with a computer

  - by Adam Geisweit

  i have tried to look up many ways to sync up my wiimotes to my computer so that i can program games with it, but every time it only syncs them up temporarily, or if it says it can permanently sync it, it doesn't actually do it. it gets tiresome when i have to keep on reconnecting it every time i want to save battery life. how would i be able to sync up my wiimote to my computer so that if i turn off my wiimote, i can just hit any button and it will automatically sync it up?

• Resolving collisions between dynamic game objects

  - by TheBroodian

  I've been building a 2D platformer for some time now, I'm getting to the point where I am adding dynamic objects to the stage for testing. This has prompted me to consider how I would like my character and other objects to behave when they collide. A typical staple in many 2D platformer type games is that the player takes damage upon touching an enemy, and then essentially becomes able to pass through enemies during a period of invulnerability, and at the same time, enemies are able to pass through eachother freely. I personally don't want to take this approach, it feels strange to me that the player should receive arbitrary damage for harmless contact to an enemy, despite whether the enemy is attacking or not, and I would like my enemies' interactions between each other (and my player) to be a little more organic, so to speak. In my head I sort of have this idea where a game object (player, or non player) would be able to push other game objects around by manner of 'pushing' each other out of one anothers' bounding boxes if there is an intersection, and maybe correlate the repelling force to how much their bounding boxes are intersecting. The problem I'm experiencing is I have no idea what the math might look like for something like this? I'll show what work I've done so far, it sort of works, but it's jittery, and generally not quite what I would pass in a functional game: //Clears the anti-duplicate buffer collisionRecord.Clear(); //pick a thing foreach (GameObject entity in entities) { //pick another thing foreach (GameObject subject in entities) { //check to make sure both things aren't the same thing if (!ReferenceEquals(entity, subject)) { //check to see if thing2 is in semi-near proximity to thing1 if (entity.WideProximityArea.Intersects(subject.CollisionRectangle) || entity.WideProximityArea.Contains(subject.CollisionRectangle)) { //check to see if thing2 and thing1 are colliding. if (entity.CollisionRectangle.Intersects(subject.CollisionRectangle) || entity.CollisionRectangle.Contains(subject.CollisionRectangle) || subject.CollisionRectangle.Contains(entity.CollisionRectangle)) { //check if we've already resolved their collision or not. if (!collisionRecord.ContainsKey(entity.GetHashCode())) { //more duplicate resolution checking. if (!collisionRecord.ContainsKey(subject.GetHashCode())) { //if thing1 is traveling right... if (entity.Velocity.X > 0) { //if it isn't too far to the right... if (subject.CollisionRectangle.Contains(new Microsoft.Xna.Framework.Rectangle(entity.CollisionRectangle.Right, entity.CollisionRectangle.Y, 1, entity.CollisionRectangle.Height)) || subject.CollisionRectangle.Intersects(new Microsoft.Xna.Framework.Rectangle(entity.CollisionRectangle.Right, entity.CollisionRectangle.Y, 1, entity.CollisionRectangle.Height))) { //Find how deep thing1 is intersecting thing2's collision box; float offset = entity.CollisionRectangle.Right - subject.CollisionRectangle.Left; //Move both things in opposite directions half the length of the intersection, pushing thing1 to the left, and thing2 to the right. entity.Velocities.Add(new Vector2(-(((offset * 4) * (float)gameTime.ElapsedGameTime.TotalMilliseconds)), 0)); subject.Velocities.Add(new Vector2((((offset * 4) * (float)gameTime.ElapsedGameTime.TotalMilliseconds)), 0)); } } //if thing1 is traveling left... if (entity.Velocity.X < 0) { //if thing1 isn't too far left... if (entity.CollisionRectangle.Contains(new Microsoft.Xna.Framework.Rectangle(subject.CollisionRectangle.Right, subject.CollisionRectangle.Y, 1, subject.CollisionRectangle.Height)) || entity.CollisionRectangle.Intersects(new Microsoft.Xna.Framework.Rectangle(subject.CollisionRectangle.Right, subject.CollisionRectangle.Y, 1, subject.CollisionRectangle.Height))) { //Find how deep thing1 is intersecting thing2's collision box; float offset = subject.CollisionRectangle.Right - entity.CollisionRectangle.Left; //Move both things in opposite directions half the length of the intersection, pushing thing1 to the right, and thing2 to the left. entity.Velocities.Add(new Vector2((((offset * 4) * (float)gameTime.ElapsedGameTime.TotalMilliseconds)), 0)); subject.Velocities.Add(new Vector2(-(((offset * 4) * (float)gameTime.ElapsedGameTime.TotalMilliseconds)), 0)); } } //Make record that thing1 and thing2 have interacted and the collision has been solved, so that if thing2 is picked next in the foreach loop, it isn't checked against thing1 a second time before the next update. collisionRecord.Add(entity.GetHashCode(), subject.GetHashCode()); } } } } } } } } One of the biggest issues with my code aside from the jitteriness is that if one character were to land on top of another character, it very suddenly and abruptly resolves the collision, whereas I would like a more subtle and gradual resolution. Any thoughts or ideas are incredibly welcome and helpful.

• What are the advantages and challenges of using HaXe over ActionScript 3?

  - by Arthur Wulf White

  I read this: http://webr3.org/blog/haxe/bitmapdata-vectors-bytearrays-and-optimization/ And this: http://stackoverflow.com/questions/5220045/what-are-the-pro-and-cons-of-using-haxe-over-actionscript-3 http://www.haxenme.org/developers/documentation/actionscript-developers/ I read there are only two books, is that right? http://haxe.org/doc/book I also see that using FlashDevelop you can make an Adobe Air project with HaXe and compile to exe. And begun to wonder from a game making perspective: I saw the example in the first link, are there any additional advantages in performance when using HaXe instead of AS3 for games development (for the web)?

• Designing a "Grid" like object that contains game objects

  - by liortal

  I am working on a 2D game, where there's a game "board" on which other game objects are placed. This this is 2D, my starting point was to design a class that will internally use a 2d array for the actual stored game objects. This class could be simply accessed by 2 indices: (i, j) to get game objects on it. My problem is that i have no idea how to make the game "board" "propagate" its data onto its children. Design questions i ran into are: Should the children placed on the board have display properties such as size, screen position? Should the board itself dictate this information? How to update children in case the board changes some of its properties? (position, etc). Should the board be aware of the types of objects stored in it ? I have no idea how similar things such as WPF or other UI frameworks go about organizing a "container like" object that can arrange or apply certain UI properties to its children.

• Faking Display tree (Sprite) parent child relationships with rasters (BitmapData) in ActionScript 3

  - by Arthur Wulf White

  I am working with Rasters (bitmapData) and blliting (copypixels) in a 2d-game in actionscript 3. I like how you can move a sprite and it moves all it's children, and you can simultaneously move the children creating an interesting visual effect. I do not want to use rotation or scaling however cause I do not know how that can be done without hampering with performance. So I'm not simulating Sprite parent-child behavior and sticking to the movement on the (x, y) axis. What I am planning to do is create a class called RasterContainer which extends bitmapData that has a vector of children of type Raster(extending bitmapData), now I am planning to implement recursive rendering in RasterContainer, that basically copyPixels every child, only changing their (x, y) offset to reflect their parent's offset. My question is, has this been implemented in an existing framework? Is this a good plan? Do I expect a serious performance hit for using recursive methods this way?

• SQL queries to determine all values that would satisfy an arbitrary query

  - by jasterm007

  I'm trying to figure out how to efficiently run a set of queries that will provide a new table of all values that would return results for an arbitrary query. Say my table has a schema like: id name age city What is an efficient way to list all values that would return results for an arbitrary query, say "NOT city=X AND age BETWEEN Y and Z"? My naive approach for this would be to use a script and recurse through all possible combinations of {city, age, age} and see which SELECTs return more than 0 results, but that seems incredibly inefficient. I've also tried building large joins on {city, age, age} as well and basically using that table as an argument list to the query, but that quickly becomes an impossibility for queries on many columns. For simple conjunctive equality queries, i.e. "name=X and age=Y", this is much simpler, as I can do something like SELECT name, age, count(*) AS count FROM main GROUP BY name, age HAVING count > 0 But I'm having difficulty coming up with a general approach for anything more complicated than that. Any pointers in the right direction would be most helpful, thanks.

• error catching exception while System.out.print

  - by user1702633

  I have 2 classes, one that implements a double lookup( int i); and one where I use that lookup(int i) in solving a question, or in this case printing the lookup values. This case is for an array. So I read the exception documentation or google/textbook and come with the following code: public double lookup(int i) throws Exception { if( i > numItems) throw new Exception("out of bounds"); return items[i]; } and take it over to my class and try to print my set, where set is a name of the object type I define in the class above. public void print() { for (int i = 0; i < set.size() - 1; i++) { System.out.print(set.lookup(i) + ","); } System.out.print(set.lookup(set.size())); } I'm using two print()'s to avoid the last "," in the print, but am getting an unhandled exception Exception (my exception's name was Exception) I think I have to catch my exception in my print() but cannot find the correct formatting online. Do I have to write catch exception Exception? because that gives me a syntax error saying invalid type on catch. Sources like http://docs.oracle.com/javase/tutorial/essential/exceptions/ are of little help to me, I'm can't seem to grasp what the text is telling me. I'm also having trouble finding sources with multiple examples where I can actually understand the coding in the examples. so could anybody give me a source/example for the above catch phrase and perhaps a decent source of examples for new Java programmers? my book is horrendous and I cannot seem to find an understandable example for the above catch phrase online.

• How to select the range for pasting using vba

  - by user1616384

  I wrote some code for selecting the particular row and pasting it in column wise using paste-special property. It is working correctly my code is : lngRow = Me.TextBox4.Value strCol = Me.TextBox5.Value Set rng = Range("A:A").Find(What:=lngRow, LookIn:=xlValues, LookAt:=xlWhole) If rng Is Nothing Then MsgBox "Value not found in row 1", vbExclamation Else Range(rng, rng.End(xlToRight)).Copy Range("A1:E3").Columns(strCol).Offset(, 1).PasteSpecial Transpose:=True Range("A1:E3").Rows(1).Copy Range("A1:E3").Columns(strCol).PasteSpecial Transpose:=True endif the problem here is I am using Range(rng, rng.End(xlToRight)).Copy to copy the values and for pasting I am using Range("A1:E3").Columns(strCol).Offset(, 1).PasteSpecial Transpose:=True. How can I paste all the values which are copied? Because if the values are in column F then this macro will not paste those values.

• AD - Using UserPrincipal.FindByIdentity and PrincipalContext with nested OU - C#

  - by Solid Snake

  Here is what I am trying to achieve: I have a nested OU structure that is about 5 levels deep. OU=Portal,OU=Dev,OU=Apps,OU=Grps,OU=Admin,DC=test,DC=com I am trying to find out if the user has permissions/exists at OU=Portal. Here's a snippet of what I currently have: PrincipalContext domain = new PrincipalContext( ContextType.Domain, "test.com", "OU=Portal,OU=Dev,OU=Apps,OU=Grps,OU=Admin,DC=test,DC=com"); UserPrincipal user = UserPrincipal.FindByIdentity(domain, myusername); PrincipalSearchResult<Principal> group = user.GetAuthorizationGroups(); For some unknown reason, the value user generated from the above code is always null. However, if I were to drop all the OU as follows: PrincipalContext domain = new PrincipalContext( ContextType.Domain, "test.com", "DC=test,DC=com"); UserPrincipal user = UserPrincipal.FindByIdentity(domain, myusername); PrincipalSearchResult<Principal> group = user.GetAuthorizationGroups(); this would work just fine and return me the correct user. I am simply trying to reduce the number of results as opposed to getting everything from AD. Is there anything that I am doing wrong? I've googled for hours and tested various combinations without much luck. Any help is appreciated. Thanks. Dan

• Money vs. Decimal vs. Float Performance issues (SQL data types for Currency value)?

  - by urz shah

  What data type should be selected in case of Currency value column in SQL server. I have read some where on web Working on customer implementations, we found some interesting performance numbers concerning the money data type. For example, when Analysis Services was set to the currency data type (from double) to match the SQL Server money data type, there was a 13% improvement in processing speed (rows/sec). Is it true??

• Efficient way to organise data file in columns with Python

  - by user1700959

  I'm getting an output data file of a program which looks like this, with more than one line for each time step: 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 7.9819E-06 1.7724E-02 2.3383E-02 3.0048E-02 3.8603E-02 4.9581E-02 5.6635E-02 4.9991E-02 3.9052E-02 3.0399E-02 .... I want to arrange it in ten columns I have made a Python script, using regular expressions to delete \n in the proper lines, but I think that there should be a simpler more elegant way to do it, here is my script: import re with open('inputfile', encoding='utf-8') as file1: datai=file1.read() dataf=re.sub(r'(?P<nomb>( \d\.\d\d\d\dE.\d\d){8})\n','\g<nomb>',datai) with open('result.txt',mode='w',encoding='utf-8') as resultfile: resultfile.write(datof) Thanks in advance

• Bind an Incode DataTemplate in WPF

  - by Mike Bynum

  I have a WPF Application which is using MVVM. I know that there ways of doing this in XAML but I am working on a plugin architecture and came up with a solution where a plugin exposes it's viewmodel to my plugin host's viewmodel and it's datatemplate. I want to leave the lifetime management of the plugin view up to WPF. I have tried having the plugins expose a UserControl but ran into issues when WPF decided to dispose of my UserControl so I would not reattach it without weird hacky work arounds. I am having issues getting some sort of binding working to where i can bind a control to the data and it's template to my data template. I have a ViewModel which looks something like: public class MyViewModel { public DataTemplate SelectedTemplate{ get; set;} public object SelectedViewModel {get; set;} } The selected template and viewmodel are determined somewhere else in the code but are irrelevant to my question. My question is how i can bind to a DataTemplate so that I know how to display the data shown in the SelectedViewModel. The DataTemplate is a DataTemplate created incode which respresents: <DataTemplate DataType="{x:Type vm:MyViewModel}"> <v:MyUserControl /> </DataTemplate> I have tried: <UserControl Template="{Binding Path=SelectedTemplate}" Content="{Binding Path=SelectedViewModel"} /> But UserControl expects a control template and not a data template.

• Accessing Item Fields via Sitecore Web Service

  - by Catch

  I am creating items on the fly via Sitecore Web Service. So far I can create the items from this function: AddFromTemplate And I also tried this link: http://blog.hansmelis.be/2012/05/29/sitecore-web-service-pitfalls/ But I am finding it hard to access the fields. So far here is my code: public void CreateItemInSitecore(string getDayGuid, Oracle.DataAccess.Client.OracleDataReader reader) { if (getDayGuid != null) { var sitecoreService = new EverBankCMS.VisualSitecoreService(); var addItem = sitecoreService.AddFromTemplate(getDayGuid, templateIdRTT, "Testing", database, myCred); var getChildren = sitecoreService.GetChildren(getDayGuid, database, myCred); for (int i = 0; i < getChildren.ChildNodes.Count; i++) { if (getChildren.ChildNodes[i].InnerText.ToString() == "Testing") { var getItem = sitecoreService.GetItemFields(getChildren.ChildNodes[i].Attributes[0].Value, "en", "1", true, database, myCred); string p = getChildren.ChildNodes[i].Attributes[0].Value; } } } } So as you can see I am creating an Item and I want to access the Fields for that item. I thought that GetItemFields will give me some value, but finding it hard to get it. Any clue?

• Rhomobile vs. Phonegap considerations

  - by NewB

  I'm debating between Phonegap and RhoMobile for cross platform mobile application development. I'm a web developer with experience in Ruby as well as the traditional web technologies (HTML, CSS, and Javascript). The backend of this application will be accessed via a web browser and built with Rails. What are my chief concerns when choosing between these platforms? Which would you recommend I go with and WHY? Thank you

• Autofac WCF integration + sessions

  - by Michael Sagalovich

  I am having an ASP.NET MVC 3 application that collaborates with a WCF service, which is hosted using Autofac host factory. Here are some code samples: .svc file: <%@ ServiceHost Language="C#" Debug="true" Service="MyNamespace.IMyContract, MyAssembly" Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %> Global.asax of the WCF service project: protected void Application_Start(object sender, EventArgs e) { ContainerBuilder builder = new ContainerBuilder(); //Here I perform all registrations, including implementation of IMyContract AutofacServiceHostFactory.Container = builder.Build(); } Client proxy class constructor (MVC side): ContainerBuilder builder = new ContainerBuilder(); builder.Register(c => new ChannelFactory<IMyContract>( new BasicHttpBinding(), new EndpointAddress(Settings.Default.Url_MyService))) .SingleInstance(); builder.Register(c => c.Resolve<ChannelFactory<IMyContract>>().CreateChannel()) .UseWcfSafeRelease(); _container = builder.Build(); This works fine until I want WCF service to allow or require sessions ([ServiceContract(SessionMode = SessionMode.Allowed)], or [ServiceContract(SessionMode = SessionMode.Required)]) and to share one session with the MVC side. I changed the binding to WSHttpBinding on the MVC side, but I am having different exceptions depending on how I tune it. I also tried changing AutofacServiceHostFactory to AutofacWebServiceHostFactory, with no result. I am not using config file as I am mainly experimenting, not developing real-life application, but I need to study the case. But if you think I can achieve what I need only with config files, then OK, I'll use them. I will provide exception details for each combination of settings if required, I'm omitting them not to make the post too large. Any ideas on what I can do?

• jquery mobile - loading content into a div

  - by Robbiegod

  Jquery Mobile works by “hijacking” a page and loading content and injecting it into the page. It seems that this creates a problem when i try to inject other content into the page. I have my index.html and then a page2.html file. I'm setting up jquery mobile in the normal fashion wrapping the contents of each page in a div like so: <div id="container" data-role="page"> // my content <a href="page2.html">go to page 2</a> </div> when the user taps go to page 2, it does the nice slide effect. The url in the location bar looks like this: index.html#page2.html jquery mobile inject the content of the page using the anchors and applies the transition. nice so everthing works great up to the next part. On page2.html, i have a section that is loading some external data and injecting it into a div. <a href="http://www.somedomain.com/myata.php" class="ajaxtrigger" data-role="none">mydata</a> <div id="target"></div> <script src="js/code.js"></script> <script src="js/loader.js"></script> <script type="text/javascript"> $(document).ready(function(){ $('.ajaxtrigger').trigger('click'); }); </script> The problem i am having is that when i enable the transitions in jquery mobile this script doesn't work. It won't load the data into the div. bummer. Anyone know what i need to do to get it to trigger and load the content into that div?

• Uncaught TypeError: Cannot read property 'length' of undefined

  - by AnApprentice

  I'm working to built a contact list that is grouped by the first letter of the contact's last name. After a succesfull ajax request, the contact is pushed to addContact: Ajax success: ko.utils.arrayForEach(dataJS.contactList, function(c) { contactsModel.addContact(c); }); contactsModel.addContact: //add a contact in the right spot under the right letter contactsModel.addContact = function(newContact) { //grab first character var firstLetter = (newContact.lname || "").charAt(0).toUpperCase(); //if it is a number use # if (!isNaN(firstLetter)) { firstLetter = "#"; } //do we already have entries for this letter if (!this.letterIndex[firstLetter]) { //new object to track this letter's contacts var letterContacts = { letter: firstLetter, contacts: ko.observableArray([]) }; this.letterIndex[firstLetter] = letterContacts; //easy access to it //put the numbers at the end if (firstLetter === "#") { this.contactsByLetter.push(letterContacts); } else { //add the letter in the right spot for (var i = 0, lettersLength = this.contactsByLetter().length; i < lettersLength; i++) { var letter = this.contactsByLetter()[i].letter; if (letter === "#" || firstLetter < letter) { break; } } this.contactsByLetter.splice(i, 0, letterContacts); } } var contacts = this.letterIndex[firstLetter].contacts; //now we have a letter to add our contact to, but need to add it in the right spot var newContactName = newContact.lname + " " + newContact.fname; for (var j = 0, contactsLength = contacts().length; j < contactsLength; j++) { var contactName = contacts()[j].lName + " " + contacts()[j].fName; if (newContactName < contactName) { break; } } //add the contact at the right index contacts.splice(j, 0, newContact); }.bind(contactsModel); The contacts json object from the server looks like this: { "total_pages": 10, "page": page, "contactList": [{ "photo": "http://homepage.mac.com/millhouse/Family%20Tree/images/PersonListIcon.png", "lname": "Bond", "id": 241, "fname": "James", "email": "[email protected]"}, While this works in jsfiddle, when I try it locally, I get the following error during the first push to addContact: Uncaught TypeError: Cannot read property 'length' of undefined jQuery.jQuery.extend._Deferred.deferred.resolveWithjquery-1.5.1.js:869 donejquery-1.5.1.js:6591 jQuery.ajaxTransport.send.callbackjquery-1.5.1.js:7382 Ideas?

• (iOS) UI Automation AlertPrompt button/textField accessiblity

  - by lipd

  I'm having a bit of trouble with UI Automation (the built in to iOS tool) when it comes to alertView. First off, I'm not sure where I can set the accessibilityLabel and such for the buttons that are on the alertView. Secondly, although I am not getting an error, I can't get my textField to actually set the value of the textField to something. I'll put up my code for the alertView and the javaScript I am using for UI Automation. UIATarget.onAlert = function onAlert(alert) { // Log alerts and bail, unless it's the one we want var title = alert.name(); UIALogger.logMessage("Alert with title '" + title + "' encountered!"); alert.logElementTree(); if (title == "AlertPrompt") { UIALogger.logMessage(alert.textFields().length + ''); target.delay(1); alert.textFields()["AlertText"].setValue("AutoTest"); target.delay(1); return true; // Override default handler } else return false; } var target = UIATarget.localTarget(); var application = target.frontMostApp(); var mainWindow = application.mainWindow(); mainWindow.logElementTree(); //target.delay(1); //mainWindow.logElementTree(); //target.delay(1); var tableView = mainWindow.tableViews()[0]; var button = tableView.buttons(); //UIALogger.logMessage("Num buttons: " + button.length); //UIALogger.logMessage("num Table views: " + mainWindow.tableViews().length); //UIALogger.logMessage("Number of cells: " + tableView.cells().length); /*for (var currentCellIndex = 0; currentCellIndex < tableView.cells().length; currentCellIndex++) { var currentCell = tableView.cells()[currentCellIndex]; UIALogger.logStart("Testing table option: " + currentCell.name()); tableView.scrollToElementWithName(currentCell.name()); target.delay(1); currentCell.tap();// Go down a level target.delay(1); UIATarget.localTarget().captureScreenWithName(currentCell.name()); //mainWindow.navigationBar().leftButton().tap(); // Go back target.delay(1); UIALogger.logPass("Testing table option " + currentCell.name()); }*/ UIALogger.logStart("Testing add item"); target.delay(1); mainWindow.navigationBar().buttons()["addButton"].tap(); target.delay(1); if(tableView.cells().length == 5) UIALogger.logPass("Successfully added item to table"); else UIALogger.logFail("FAIL: didn't add item to table"); Here's what I'm using for the alertView #import "AlertPrompt.h" @implementation AlertPrompt @synthesize textField; @synthesize enteredText; - (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle withOrientation:(UIInterfaceOrientation) orientation { if ((self == [super initWithTitle:title message:message delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])) { self.isAccessibilityElement = YES; self.accessibilityLabel = @"AlertPrompt"; UITextField *theTextField; if(orientation == UIInterfaceOrientationPortrait) theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)]; else theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 30.0, 260.0, 25.0)]; [theTextField setBackgroundColor:[UIColor whiteColor]]; [self addSubview:theTextField]; self.textField = theTextField; self.textField.isAccessibilityElement = YES; self.textField.accessibilityLabel = @"AlertText"; [theTextField release]; CGAffineTransform translate = CGAffineTransformMakeTranslation(0.0, 0.0); [self setTransform:translate]; } return self; } - (void)show { [textField becomeFirstResponder]; [super show]; } - (NSString *)enteredText { return [self.textField text]; } - (void)dealloc { //[textField release]; [super dealloc]; } @end Thanks for any help!
