Unity3D : Blur the background of a UI canvas

為{幸葍}努か 提交于 2019-12-03 12:43:11
I'm trying to reproduce the (now common famous) blur effect on the background of a UI window for my game in Unity3D. One of the best examples I can think of right now is Heroes Of The Storm, notice how the background of the Level Up panel blurs what's behind it : Is there any way to reproduce the same effect with the recently-added Canvas in Unity3D? I know there is a way to do so by using a camera, but I'm not really familiar with the whole thing, especially when it comes to making it work with the new UI system. Thanks. Here's a shader script that works nicely for me. Source: https://forum

问题 How do you use Visual Effect Views with Blur and Vibrancy in Interface Builder? I've dragged this item out into the View, then dragged a UILabel onto the last view in the hierarchy - the vibrant effect's contentView I assume. This results in a blurred view overtop but there is no label visible. Anywhere else I place the label in the hierarchy it does become visible but it's just solid black text. 回答1: Finally figured it out. In a UIViewController change the view's background to blue Drag a

I'm using a stock UISplitViewController with out-of-the-box Master and Detail view controllers. In a storyboard, I've added a UIImageView to the Detail controller set to effectively fill the view with a single image. In the Master controller, I've used the following to blur the background of that controller: // In viewDidLoad self.tableView.backgroundColor = [UIColor clearColor]; UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark]; UIVisualEffectView *visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect]; self.tableView.backgroundView =

Detect if device properly displays UIVisualEffectView?

ぃ、小莉子 提交于 2019-11-30 17:40:06
My app utilizes UIVisualEffectView to blur the background just like Control Center. But I discovered the iPad 2 (and Retina iPad) which can run iOS 8 isn't powerful enough to display that effect so it reverts to a gray color. I would like to be able to detect if the device the app is running on is powerful enough to display the blur effect, and if not I won't apply it, instead I'll change the background color to something that looks much better than that gray color. But I don't want to just check if the device is an iPad 2 or iPad 3rd gen (does it affect 4th as well?). Is there a better way to

问题 How to make the Navigation Bar and Status Bar blurred (UIBlurEffect)?

NO UIBlurEffect I have tried so, but did not work: func addBlurEffect() { // Add blur view let bounds = self.navigationController?.navigationBar

How to fade a UIVisualEffectView and/or UIBlurEffect in and out?
