  • software for sorting algorithms animation

    - by Dinesh
    I am planning on working on an interactive application that graphically animates the various sorting algorithms in action. Most of the examples of this kind on the web seems to be using java applets. I was wondering what other software/tools would be well suited to develop an application like this. It may or may not be web-based. Any help would be greatly appreciated. Thanks Dinesh

  • jQuery - color cycle animation with hsv colorspace?

    - by Sgt. Floyd Pepper
    Hi there, I am working on a project, which I need a special body-background for. The background-color should cycle through the color spectrum like a mood light. So I found this: http://buildinternet.com/2009/09/its-a-rainbow-color-changing-text-and-backgrounds/ "But" this snippet is working with the RGB colorspace which has some very light and dark colors in it. Getting just bright colors will only work with the HSV colorspace (e.g. having S and V static at 100 and letting H cycle). I don’t know how to convert and in fact how to pimp this snippet for my needs. Does anyone has an idea?? Thanks in advance. Best, Floyd

  • Why don't this toggle animation execute in all browsers

    - by Sam Horner
    Hey guys This file isn't executing in any browser other than firefox on mac. Added everything i can think to get it sorted. http://samhorner.co.uk/dev/samhorner/ Clicking on the twitter bar should close it, then open it again when you click on it again, only one click works on the other browsers. The blue box is a flash area in the background. Thanks or the help. Cheers Sam

  • Disable animation when moving CALayers

    - by Sean Clark Hess
    The following code animates the movement, even though I didn't use beginAnimations:context. How do I get it to move without animating? This is a new iphone view project, and these are the only updates to it. // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; sublayer = [CALayer new]; sublayer.backgroundColor = [[UIColor redColor] CGColor]; sublayer.frame = CGRectMake(0, 0, 100, 100); [self.view.layer addSublayer:sublayer]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { sublayer.position = [[touches anyObject] locationInView:self.view]; }

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • Creating a Pop animation similar to the presentation of UIAlertView

    - by JK
    I would like to present a view in the same manner as that of UIAlertView - a pop/spring. Unfortunately subclassing UIAlertView is not an option for the view I need to present. I have written some code, but I can't seem to get it as realistic as I would like. I would appreciate any suggestions for greater realism or a link if anything similar has been done (I could not find anything on Google). Thank you. - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.backgroundColor = [UIColor whiteColor]; v = [[UIView alloc] initWithFrame:CGRectMake(140, 140, 60, 60)]; v.backgroundColor = [UIColor blueColor]; [self addSubview:v]; [self animate]; } return self; } - (void)animate { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.2]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(popStep1Complete)]; v.frame = CGRectMake(90, 90, 140, 140); [UIView commitAnimations]; } - (void)popStep1Complete { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.15]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(popStep2Complete)]; v.frame = CGRectMake(110, 110, 100, 100); [UIView commitAnimations]; } - (void)popStep2Complete { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.15]; v.frame = CGRectMake(100, 100, 120, 120); [UIView commitAnimations]; }

  • 3D Animation Rotating and Translating simultaneously in WPF

    - by sklitzz
    Hi, I have ModelVisual3D of a cube. I want to translate and rotate it at the same time. I wish the center of rotation to be in the middle of the cube(the cube rotates around its own axis). But when I try to do this applying both transformations the effect is not what you would expect. Since the object is translating the center of rotation is different thus making it move and rotate in a strange way. How do I get the desired effect? Transform3DGroup transGroup = new Transform3DGroup(); DoubleAnimation cardAnimation = new DoubleAnimation(); cardAnimation.From = 0; cardAnimation.To = 3; cardAnimation.Duration = new Duration(TimeSpan.FromSeconds(2)); Transform3D transform = new TranslateTransform3D(0,0,0); transGroup.Children.Add(transform); RotateTransform3D rotateTransform = new RotateTransform3D(); AxisAngleRotation3D rotateAxis = new AxisAngleRotation3D(new Vector3D(0, 1, 0), 180); Rotation3DAnimation rotateAnimation = new Rotation3DAnimation(rotateAxis, TimeSpan.FromSeconds(2)); rotateAnimation.DecelerationRatio = 0.8; transGroup.Children.Add(rotateTransform); Model.Transform = transGroup; transform.BeginAnimation(TranslateTransform3D.OffsetXProperty, cardAnimation); rotateTransform.BeginAnimation(RotateTransform3D.RotationProperty, rotateAnimation);

  • Activating Webkit CSS3 animation using Javascript

    - by jeffreyveon
    I am looking to use Webkit CSS3 to move a absolutely positioned DIV from one location to another on the screen when a button is pressed, by changing its left and right CSS properties. However, all the examples for doing this that I saw use a static CSS rule to apply this transition. I don't know the new position before hand, so how do I apply this CSS3 transition dynamically?

  • jQuery - Animation flicker using hover()

    - by Chris
    I have a setup as described in this question which works perfectly. Essentially a drop down menu grows when you move your mouse over it to expose more options. There is, however, a small issue. If you move the mouse outside of the #dropdown div and then back in again quickly it constantly fires the mouseenter and mouseleave events causing a never ending cycle of flickering. How can I get around it? Here is my current jQuery code $("#dropdown").hover(function() { $(this).stop(true,true).fadeTo('fast',1); $("#options").stop(true,true).slideDown(); }, function() { $(this).stop(true,true).fadeTo('fast',0.1); $("#options").stop(true,true).slideUp(); } );

  • Image animation over CGContextDrawPDFPage

    - by BittenApple
    I have a pdf page displayed with CGContextDrawPDFPage. I want to keep this page shown and have an image slide in from top over this page, just as it can be seen in the iBooks application. It's a book, the sliding image is a bookmark that slides in when you are about to close the book. What is the best way to go about implementing this?

  • jquery .animate - image gets cropped during animation

    - by stef
    Hello all, I am currently programming a carousel with javascript using the jquery library. Basically, there are three images shown, the central image being bigger than the two others. Upon going left or right, the central images is resized from 115px*115px to 50px*50px and tossed left or right, depending on the user input. The problem is that when the resize happens, the central image gets gradually cropped until it reaches the 50px*50px and then return to a more normal state: http://www.filedropper.com/imggetscropped Javascript is as follow: $("div#carousel .item:eq(2)").animate({'width':'50px', 'height':'50px', 'opacity':'0.5'}, {queue:false, duration:900}); $("div#carousel .item:eq(2) img").animate({'width':'50px', 'height':'50px', 'marginTop': '30px'}, {queue:false, duration:900}); $("div#carousel .item:eq(1)").animate({'width':'115px', 'height':'115px', 'opacity':'1'}, {queue:false, duration:900}); $("div#carousel .item:eq(1) img").animate({'width':'115px', 'height':'115px', 'marginTop': '0px'}, {queue:false, duration:900}); $("div#carousel .item:not(eq(2))").animate({'left':'+=56px'}, {queue:false, duration:900}); $("div#carousel .item:eq(2)").animate({'left':'+=122px'}, {queue:false, duration:900, complete: carousel.toggleInput}); Images used are png with transparency.

  • Button Pressed Animation be longer

    - by user1263567
    i have this button xml, when it be will pressed, the pressed image(b) would be longer to display before it goes back to normal button. Here's my xml: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/a" /> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/b" /> <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/b" /> <item android:drawable="@drawable/a" /> Anyone has idea on this?

  • How can we set time delay in animation of images to make them appear smooth ?

    - by srikanth rongali
    Hi, I have 10 CCSprite images. They are continues images. I am using, CCSprite *playerH = [CCSprite spriteWithFile:@"Player_01.png" ]; playerH.position = ccp(playerH.contentSize.width/2, windowSize.height/2); [self addChild:playerH z:1]; CCAnimation* animation = [CCAnimation animationWithName:@"dance" delay:0.20f]; for( int i = 1; i < 11; i++ ) { [animation addFrameWithFilename: [NSString stringWithFormat:@"Player_%02d.png", i]]; } NSLog(@"k VALUE: k: %d",k); id actionA = [CCAnimate actionWithAnimation: animation restoreOriginalFrame:NO]; id actionD = [CCDelayTime actionWithDuration:5.0f]; id actionC = [CCCallFunc actionWithTarget:self selector:@selector(enemyEntranceScreen:)]; id seqActionPlayer = [CCSequence actions:actionA, actionD, actionC, nil]; [playerH runAction: seqActionPlayer]; But the animation is not continues. I have changed the animation delay time. but, I can see only three images appearing. How can we know how much time interval should we keep in animation. Is there any relationship between this and the frame rate [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; Thank you.

  • 3D Studio Max biped restrictions?

    - by meds
    I have a stock biped character in 3D studio max which has a jump animation. The problem I have with the jump animation is that there is actual y offset happening inside it which makes it awkward to play while the character is jumping since it's not only jumping in the game world but the jump animation is adding its own height offset. I'm tryuing to remove the jump animations height offset, so far I've found the root node and deleted all its key frames which has helped a bit. The problem I'm having now is that the character still has some height offset and if I try to lower it it has a fake 'ground' that isn't at 0 and the limbs sort of bend on the imaginary floor, si there a way to remove this restriction just for the jump animation? Here's what I mean: http://i.imgur.com/qoWIR.png Any idea for a fix? I'm using Unity 3D if that opens any other possibilities...

  • How to handle animations?

    - by Bane
    I am coding a simple 2D engine to be used with HTML5. I already have classes such as Picture, Scene, Camera and Renderer, but now I need to work on Animations. Picture is basocally a wrapper for a normal image object, with it's own draw method, but this is unrelated, I'm interested in how animation in 2D games is usually done. What I planned to do, is to have the Animation class as well act like a wrapper for a few image objects, and then have methods such as getCurrentImage, next and animate (which would use intervals to quickly change the current image). I meant to feed the animation a couple of PNG's at inicialisation. Is quickly swapping PNG images acceptable for 2D animation? Are there some standard ways of doing this, or are there flaws in my ways?

  • Is there animation software available for Ubuntu?

    - by Robert Low
    Is there commercial-grade computer animation software available for Ubuntu, similar to the professional software sold for the Windows operating system? This question goes out to those of you who may be using such software professionally. My daughter recently graduated from the Art Institute of Seattle, and needs to put together an animation portfolio in order to interest employers in the field. As you know, such software is usually provided by the employer and the costs are high - several thousand dollars. I suggested that she investigate Ubuntu as a possible way to acquire the tools she needs. But, since I have no idea what might be available, either as open source or proprietary animation software, I am reaching out to the Ubuntu community for help in the hope someone who is using such software can help her. Thank you for reading this post, and for any information you might have.

  • Animating isometric sprites

    - by Mike
    I'm having trouble coming up with a way to animate these 2D isometric sprites. The sprites are stored like this: < Game Folder Root /Assets/Sprites/< Sprite Name /< Sprite Animation /< Sprite Direction /< Frame Number .png So for example, /Assets/Sprites/Worker/Stand/North-East/01.png Sprite sheets aren't really viable for this type of animation. The example stand animation is 61 frames. 61 frames for all 8 directions alone is huge, but there's more then just a standing animation for each sprite. Creating an sf::Texture for every image and every frame seems like it will take up a lot of memory and be hard to keep track of that many images. Unloading the image and loading the next one every single frame seems like it will do a lot of unnecessary work. What's the best way to handle this?

  • How do you handle animations that are for transitioning between states?

    - by yaj786
    How does one usually handle animations that are for going between a game object's states? For example, imagine a very simple game in which a character can only crouch or stand normally. Currently, I use a custom Animation class like this: class Animation{ int numFrames; int curFrame; Bitmap spriteSheet; //... various functions for pausing, returning frame, etc. } and an example Character class class Character{ int state; Animation standAni; Animation crouchAni; //... etc, etc. } Thus, I use the state of the character to draw the necessary animation. if(state == STATE_STAND) draw(standAni.updateFrame()); else if(state == STATE_CROUCH) draw(crouchAni.updateFrame()); Now I've come to the point where I want to draw "in-between" animations, because right now the character will just jump immediately into a crouch instead of bending down. What is a good way to handle this? And if the way that I handle storing Animations in the Character class is not a good way, what is? I thought of creating states like STATE_STANDING_TO_CROUCHING but I feel like that may get messy fast.

  • Data-driven animations

    - by saadtaame
    Say you are using C/SDL for a 2D game project. It's often the case that people use a structure to represent a frame in an animation. The struct consists of an image and how much time the frame is supposed to be visible. Is this data sufficient to represent somewhat complex animation? Is it a good idea to separate animation management code and animation data? Can somebody provide a link to animations tutorials that store animations in a file and retrieve them when needed. I read this in a book (AI game programming wisdom) but would like to see a real implementation.
