  • Play animation (storyboard) backwards

    - by drasto
    Is there a simple way to play some StoryBoad backward (reversed) ? As there is a method Storyboard.Begin() I would expect that there is some method like "Storyboard.BeginReversed()" but I cannot find it. If there is no way to play an animation backwards that I have to write for most of my animations complementary animations. That smells bad to me (code duplication of some kind). Basically I just animate a Grid that shows and than hides.

  • Jquery hover with animation

    - by Brian
    anyone know how to stop a .hover happening again before the mouseout animation has finished? I have the following code which has 4 anchors. Once hovered over the anchor the related anchor slides in using animation. My problem is you hover out and in quickly, before the square has been set back to 0px it increases the slide distance. <body class="home"> <div id="container"> <a class="page-link homet" id="anim-1"></a> <a class="page-link about" id="anim-2"></a> <a class="page-link portfolio" id="anim-3"></a> <a class="page-link contacts" id="anim-4"></a> <div id="header"> <div id="logo"> </div> <ul id="navigation"> <li><a id="1"></a></li> <li><a id="2"></a></li> <li><a id="3"></a></li> <li><a id="4"></a></li> </ul> </div> <div id="main"> <div id="left-content"> </div> <div id="main-content"> </div> </div> </div> </body> </html> Jquery var cc = { displayAnim : function () { actionLink = $("#container #header #navigation li a"); movePosition = "0"; $("#container a.page-link").css({ position:"absolute", right: 0}); $(actionLink).hoverIntent( function() { circleToReveal = $(this).attr('id'); switch (circleToReveal) { case "1" : movePostion = "386" break; case "2" : moveposition = "514" break; case "3" : movePosition = "643" break; case "4" : movePosition = "400" break; default : movePosition = "772" }; /* console.log(movePosition); */ $("#container #anim-" +circleToReveal+ "").stop().animate({"right": "+="+ movePosition +"px"}, "slow"); }, function() { $("#container #anim-" +circleToReveal+ "").stop().animate({"right": "-="+ movePosition +"px"}, "slow"); } ); } }; $(window).load (function () { $("body").addClass('js'); $("a.pagelink").hide(); cc.displayAnim(); });

  • Complex movement within animation

    - by Irwin
    I've this application, where two children are playing catch. One throws and the other catches. While I can show a ball object moving between two stationary objects, how do I show the objects "releasing" and "catching" the ball, in a way that is close to lifelike? EDIT: The movement of the hands in this game: http://www.acreativedesktop.com/animation-game-slaphands.html is what I would like to replicate. Any tips on how to do that?

  • UITableView is getting interaction when changing rows with animation

    - by Tiago
    Hi, I have a tableview on a nib file with the interaction setting turned off. I'm animating a section change like this: [myTableView beginUpdates]; [myTableView deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES]; [myTableView insertSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:YES]; [myTableView endUpdates]; The problem is that, when I do this, the rows become selectable. How do I keep the interaction disabled while keeping the animation?

  • Pausing and restarting an Animation

    - by Sandeep
    I'm running a CAKeyframeAnimation in a subclass of UIViewController. I want to pause the animation on pressing a "Pause" button and start back from where it paused on pressing a "Resume" button. I've come across an answer to a similar question on this site, but it doesn't work for me. I would appreciate any help.

  • Store XML data in Core Data

    - by ct2k7
    Hi, is there any easy way of store XML data into core data? Currently, my app just pulls the values from the XML file directly, however, this isn't efficient for XML files which holds over 100 entries, thus storing the data in Core Data would be the best option. XML file is called/downloaded/parsed ever time the app opens. With the Core Data, the XML data would be downloaded ever 3600 seconds or so, and refresh the current data in the core data, to reduce the loading time when opening the app. Any ideas on how I can do this? Having reviewed the developer documentation, it doesn't look very tasty.

  • Core Data vs. SQLitePersistentObjects

    - by Macatomy
    I'm creating an iPhone app and I'm trying to choose between 2 solutions for a persistent store. Core Data, or SQLitePersistentObjects. Basically, all my app needs is a way to store an array of model objects and then load them again to display in a UITableView. Its nothing too complicated. Core Data seems to have a much higher learning curve than the simple to use SQLitePersistentObjects. Are there any obvious benefits of using Core Data over SQLitePersistentObjects in my case?

  • Can Core Data be used on Linux?

    - by glenc
    This might be a stupid question, but I was wondering whether or not you can use the Core Data libraries on Linux at all? I'm planning how to build the server side of an iPhone app that I'm working on, and have found that you can use PyObjC to get access to Core Data in a Python environment, e.g. use Core Data in a TurboGears web application. At this point I'm thinking that you would have to run the web server on Mac OSX, because I can't find any evidence on the internet that you can access the Objective-C libraries on Linux. I've always written webapps on Linux but will obviously make the jump to an OSX server if it allows me to use the same datastore implementation on the iPhone and the server, the only job remaining being the Core Data <- Web Services XML translation that has to happen on the wire.

  • How can Core Data store an NSData?

    - by mystify
    The documentation says, that core data properties can only store NSString, NSNumber and NSDate types. However, a lot of Core Data users claim Core Data could also store an NSData type. But I wasn't able to see that in the documentation, although the Xcode Data Modeler allows to choose a data type called "binary" (which seems to be NSData). Did I miss something? Is there a hidden place in the documentation that indeed lists NSData for binary stuff?

  • Linux core dumps are too large!

    - by themoondothshine
    Hey guys, Recently I've been noticing an increase in the size of the core dumps generated by my application. Initially, they were just around 5MB in size and contained around 5 stack frames, and now I have core dumps of 2GBs and the information contained within them are no different from the smaller dumps. Is there any way I can control the size of core dumps generated? Shouldn't they be at least smaller than the application binary itself? Binaries are compiled in this way: Compiled in release mode with debug symbols (ie, -g compiler option in GCC). Debug symbols are copied onto a separate file and stripped from the binary. A GNU debug symbols link is added to the binary. At the beginning of the application, there's a call to setrlimit which sets the core limit to infinity -- Is this the problem?

  • I need help choosing between two configurations of the Dell Studio 14

    - by Adnan
    There are two configurations of the Dell Studio 14 (1458) which I'm looking at: Config 1: Core i7-720QM @ 1.6 GHz; ATI Mobility Radeon HD 5450 1GB; 4gb DDR3 RAM @ 1066 MHz; 500 GB SATA HDD @ 7200 RPM; Price: $999 Config 2: Core i5-430M; ATI Mobility Radeon HD 4530 512MB; 4GB DDR3 RAM @ 1066 MHz; 500 GV SATA HDD @ 7200 RPM; Price: $874 What I want to know is, would config 1 still be able to do decent gaming (maybe some Starcraft II), and is there a great performance difference between the i5 and i7 processors? Is the $130 extra worth it for the i7 and better graphics card? I do more than just basic computing. I plan on getting into web design (specifically using Photoshop and Dreamweaver), and I wish to do gaming. I know Conifg 1 is the better value, but I want to be sure that the $130 more is truly worth it. I dont have too much money and want to spend wisely as possible, yet I am a computer geek and plan on doing a lot more than the average user.

  • Simple animation using C#/Windows Forms

    - by clintp
    I need to knock out a quick animation in C#/Windows Forms for a Halloween display. Just some 2D shapes moving about on a solid background. Since this is just a quick one-off project I really don't want to install and learn an entire new set of tools for this. (DirectX dev kits, Silverlight, Flash, etc..) I also have to install this on multiple computers so anything beyond the basic .Net framework (2.0) would be a pain in the arse. For tools I've got VS2k8, 25 years of development experience, a wheelbarrow, holocaust cloak, and about 2 days to knock this out. I haven't done animation since using assembler on my Atari 130XE (hooray for page flipping and player/missile graphics!) Advice? Here's some of the things I'd like to know: I can draw on any empty widget (like a panel) by fiddling with it's OnPaint handler, right? That's how I'd draw a custom widget. Is there a better technique than this? Is there a page-flipping technique for this kind of thing in Windows Forms? I'm not looking for a high frame rate, just as little flicker/drawing as necessary. Thanks. Post Mortem Edit ... "a couple of coding days later" Well, the project is done. The links below came in handy although a couple of them were 404. (I wish SO would allow more than one reply to be marked "correct"). The biggest problem I had to overcome was flickering, and a persistent bug when I tried to draw on the form directly. Using the OnPaint event for the Form: bad idea. I never got that to work; lots of mysterious errors (stack overflows, or ArgumentNullExceptions). I wound up using a panel sized to fill the form and that worked fine. Using the OnPaint method is slow anyway. Somewhere online I read that building the PaintEventArgs was slow, and they weren't kidding. Lots of flickering went away when I abandoned this. Skip the OnPaint/Invalidate() and just paint it yourself. Setting all of the "double buffering" options on the form still left some flicker that had to be fixed. (And I found conflicting docs that said "set them on the control" and "set them on the form". Well controls don't have a .SetStyle() method.) I haven't tested without them, so they might be doing something (this is the form): this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); So the workhorse of the code wound up looking like (pf is the panel control): void PaintPlayField() { Bitmap bufl = new Bitmap(pf.Width, pf.Height); using (Graphics g = Graphics.FromImage(bufl)) { g.FillRectangle(Brushes.Black, new Rectangle(0, 0, pf.Width, pf.Height)); DrawItems(g); DrawMoreItems(g); pf.CreateGraphics().DrawImageUnscaled(bufl, 0, 0); } } And I just called PaintPlayField from the inside of my Timer loop. No flicker at all.

  • Background custom button animation using WPF

    - by ajtp
    Hi, I am using Resources dictionaries to customize my controls and apply them as themes to my WPF application so I have implemented one for the button control. A code snippet for my custom Button.xaml is (its namespace is MyWPFApp.Themes): <ResourceDictionary ...> ... <LinearGradientBrush x:Key="NormalBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="sc#1.000000, 0.250141, 0.333404, 0.884413" Offset="0"/> <GradientStop Color="#ccffffff" Offset="1"/> </LinearGradientBrush> <LinearGradientBrush x:Key="OverBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#da5e69" Offset="0"/> <GradientStop Color="#d12e27" Offset="1"/> </LinearGradientBrush> <LinearGradientBrush x:Key="ClickBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#d22828" Offset="1"/> <GradientStop Color="#b00000" Offset="0"/> </LinearGradientBrush> ... <Style TargetType="{x:Type Button}"> ... <Setter Property="Background" Value="{StaticResource NormalBackground}"/> ... </Style> </ResourceDictionary> and I apply it by doing the following from my main Application.xaml: <Application ...> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Themes/Button.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> What I try to do is to change background color, for example, from White to Lime for 6 seconds by doing this from one of my pages, MyPage1.xaml, using StoryBoard: <Page x:Class="MyWPFApp.Pages.MyPage1" ...> <Page.Resources> ... <Storyboard x:Key="sbBtnResetHC" Storyboard.TargetName="BtnResetHC" Storyboard.TargetProperty="(Background). (SolidColorBrush.Color)"> <ColorAnimation From="Pink" To="Green" By="Blue" Duration="0:0:6" RepeatBehavior="3x" AutoReverse="True" /> </Storyboard> ... </Page.Resources> ... <Button x:Name="BtnResetHC" Click="BtnResetHC_Click" Width="90" Visibility="Collapsed" /> ... </Page> and from code behind MyPage1.xaml.cs I start animation by doing this: Storyboard sb = (Storyboard)FindResource("sbBtnResetHC"); sb.Begin(); when the button is visible, but it doesn't work for me. Any ideas what's wrong? Maybe another possibility, as I want the animation starts on button visible is to do a trigger for the button over Visibility property, Is it a better solution? Thanks a lot!

  • UIView to Form Sheet flip animation rotation issue

    - by GSD
    I have this view to form sheet flip animation that works great in portrait mode but not in any other orientations. In my code, I use it with a UIView embedded in another UIView, which is in the root view. The animation will be rotated. Anyone has an idea why? - (void)presentModalViewControllerWithFlipAnimation:(UIViewController *)modalViewController fromView:(UIView *)fromView { UIWindow* window = [[UIApplication sharedApplication] windows][0]; _fromViewSnapshot = [[UIImageView alloc] initWithFrame:fromView.bounds]; UIGraphicsBeginImageContext(fromView.bounds.size); [fromView.layer renderInContext:UIGraphicsGetCurrentContext()]; [_fromViewSnapshot setImage:UIGraphicsGetImageFromCurrentImageContext()]; [_fromViewSnapshot sizeToFit]; UIGraphicsEndImageContext(); _fromViewSnapshot.autoresizesSubviews = YES; _fromViewSnapshot.frame = [fromView.superview convertRect:fromView.frame toView:window]; [window addSubview:_fromViewSnapshot]; fromView.hidden = YES; modalViewController.modalPresentationStyle = UIModalPresentationFormSheet; [self presentViewController:modalViewController animated:NO completion:nil]; UIView __weak *presentedView = modalViewController.view.superview; UIGraphicsBeginImageContext(presentedView.bounds.size); [presentedView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage* modalSnapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIView __weak *presentationSuperview = presentedView.superview; [presentedView removeFromSuperview]; UIImageView* presentationSnapshotView = [[UIImageView alloc] initWithImage:modalSnapshot]; presentationSnapshotView.autoresizingMask = UIViewAutoresizingNone; [_fromViewSnapshot.superview bringSubviewToFront:_fromViewSnapshot]; [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionBeginFromCurrentState animations: ^{ [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations: ^{ _fromViewSnapshot.frame = [_fromViewSnapshot.superview convertRect:presentedView.frame fromView:presentationSuperview]; } completion:nil]; } completion:^(BOOL finished) { [UIView setAnimationBeginsFromCurrentState:YES]; [UIView transitionWithView:_fromViewSnapshot duration:kFlipAnimationSpeed options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionTransitionFlipFromRight animations: ^{ presentationSnapshotView.frame = _fromViewSnapshot.bounds; [_fromViewSnapshot addSubview:presentationSnapshotView]; } completion:^(BOOL finished) { [presentationSuperview addSubview:presentedView]; [presentationSnapshotView removeFromSuperview]; [_fromViewSnapshot removeFromSuperview]; }]; }]; } - (void)dismissViewControllerWithFlipAnimation:(UIView*)fromView completion:(void (^)(void))completion { UIWindow* window = [[UIApplication sharedApplication] windows][0]; UIView __weak *presentedView = self.presentedViewController.view.superview; UIGraphicsBeginImageContext(presentedView.bounds.size); [presentedView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage* modalSnapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [presentedView removeFromSuperview]; UIImageView* presentationSnapshotView = [[UIImageView alloc] initWithImage:modalSnapshot]; presentationSnapshotView.autoresizingMask = UIViewAutoresizingNone; presentationSnapshotView.frame = presentedView.frame; [window addSubview:presentationSnapshotView]; [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionBeginFromCurrentState animations: ^{ [UIView animateWithDuration:kFlipAnimationScaleSpeed delay:0 options:UIViewAnimationOptionBeginFromCurrentState animations: ^{ presentationSnapshotView.frame = [fromView.superview convertRect:fromView.frame toView:window]; } completion:nil]; } completion:^(BOOL finished) { [UIView setAnimationBeginsFromCurrentState:YES]; [UIView transitionWithView:presentationSnapshotView duration:kFlipAnimationSpeed options:UIViewAnimationOptionCurveEaseIn|UIViewAnimationOptionTransitionFlipFromLeft animations: ^{ _fromViewSnapshot.frame = presentationSnapshotView.bounds; [presentationSnapshotView setImage:[(UIImageView*)_fromViewSnapshot image]]; [self dismissViewControllerAnimated:NO completion:nil]; } completion:^(BOOL finished) { [presentationSnapshotView removeFromSuperview]; _fromViewSnapshot = nil; completion(); }]; }]; }

  • uiview animation used to work on iphone sdk 2.2 and now it doesn't on sdk 3.0

    - by nico
    hello! I have an animation block that worked fine when runnung the app on iphone OS 2.2. Now I compile the same code for iphone OS 3.0 and it doesn't work. UIViewAnimationTransition trans = UIViewAnimationTransitionFlipFromLeft; [UIView beginAnimations: nil context: NULL]; UIView *forview = [[self view] superview]; [UIView setAnimationTransition: trans forView:forview cache: YES]; [UIView setAnimationDuration:1.0]; [[self navigationController] popViewControllerAnimated:NO]; [UIView commitAnimations]; What the code does, it uses the navigation controller to change the top most view, but with the flip transition and not with the built in one. any ideas on what might have change in the sdk or what I'm doing wrong? thanks!!

  • Tween Animation Cannot Start

    - by David Dimalanta
    Do you have any reasons why my tween code didn't run or work? I already add the tween engine onto the library folder under LibGDX project folder and "Order and Export" it under Java Build Path at the Properties menu. My first two classes ran correctly and workly but my third class didn't work. Here's the sequence: First class is the first screen. Fade animation works on the company's logo. Second class is the second screen. Fade animation for the loading screen works. Third class is the third screen. After the second screen, now calls for the third screen. Animation stopped or won't run since I want the black screen to fade out at the start when the menu is here. Can you check if I did right? Look carefully by comment lines for explanation. //-----[ Animation Setup ]----- Tween.registerAccessor(Sprite.class, new Tween_Animation()); // --> Tween_Animation.java Tween_Manager = new TweenManager(); // --> I initialized it the TweenManager and seems okay. cb_start = new TweenCallback() // --> I'll use this when I choose START and the menu will fade in black. { @Override public void onEvent(int arg0, BaseTween<?> arg1) { goTo(); } }; Tween // --> This is where I focused the problem. .to(black_Sprite, Tween_Animation.ALPHA, 3f) .target(1) .ease(TweenEquations.easeInQuad) .repeatYoyo(200, 2.5f) // --> I set the repeat for 200 times when I noticed that the animation won't work! .start(Tween_Manager);

  • How to Animate a Gradient on a Path to visualize data flow in WPF/WCF app

    - by John
    I have an interesting project where several "nodes" on a cnavas are connected via a Path similiar to a mindmap tree. The path is used to visualize the connection state between two nodes. Red means the nodes are disconnected, green means they're connected. The next step would be to illustrate data flow (from A to B or B to A) using that path and an animation. Basically I would want to start the animation with the data transfer and stop it when the transfer is complete. Does anyone know how this could be done in WPF?

  • addSubview animation

    - by Mike
    I have main UIView where I display different data. Then I put a button, which displays subview like this: - (IBAction) buttonClicked: (id) sender { UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(25,25,50,20)]; UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(25,25, 50,25)]; newLabel.text = @"some text"; [newView addSubview: newLabel]; [self.view addSubview: newView]; [newLabel release]; [newView release]; } newView appears fine, but it doesn't animate itself any way, it just appears immediately. How can I add some kind of animation when newView appears? Like zoom or slide down or something like that. Is there some simple code?
