transitions

Can someone provide an example of how to progressively blur a SKSpriteNode's image using Apple's Sprite Kit? For instance, let's say the user touches a button on the screen which will then trigger the background to slowly (i.e. progressively) blur until it reaches a specific threshold. Ideally, I would like to reverse the process too (e.g. allow the user to unblur the image by touching the same button). There are two possible paths to take on this, both use SKEffectNodes SKEffectNodes allow you to apply CI Filters to a node. There is a CI Filter for Gaussian Blur. So Create a SKEffectNode, and

I have two html pages: Page1.html, Page2.html. I would like to slide between the two pages. I have found a lot of plugins and solutions to slide between two divs or slide within a container but what I need is a complete page change. I found something but the problem is that jquery code on page2 does not fire when the page loads. I could use jQuery mobile but my project uses jQuery ui and it gives me some conflicts... so I need something else. The project is supposed to run on iPad so it would be cool to have sliding pages that you can drag. But I would be happy to just find a plugin for the

I'm using d3 to animate a route (path) on a map. When the route reaches a point along the route I'd like to popup some information. Most of my code is based on the following example. http://bl.ocks.org/mbostock/1705868 . I'm really just trying to determine if there is a way to detect when the transitioning circle collides or overlaps any of the stationary circles in this example. You can detect collision in your tween function. Define a collide function to be called from inside the tween function as follows: function collide(node){ var trans = d3.transform(d3.select(node).attr("transform"))

Note: I began writing this question, and in writing it up ended up solving the problem. I'll leave it here and hopefully it will help someone else. I've been pounding my head against the wall with this for a while now and keep getting inconsistent results. Attempt 1 (from here ) App.ApplicationController = Ember.Controller.extend({ routeChanged: function (){ mixpanel.track("pageview", {"url": window.location.href }); }.observes('currentPath') }); I had to deviate from the example since mixpanel.track_pageview() is deprecated. This resulted in incorrect location logging since I can't find a way

I have a custom UIViewControllerAnimationTransition class created already, and need to make this animate a UITabBarController when it switches tabs. The tabBarController does not use the regular tab bar, though. I have a custom implementation that acts like it, and when a button is pressed, it calls this code: tabBarController.selectedIndex = index Currently I have the tabBarController (subclass) as the delegate for its own transitionDelegate . The delegate method animationControllerForPresentedController is never actually called, though. Is it fine for the tab bar controller to be its own
