Flip a sprite in canvas

纵然是瞬间 提交于 2019-11-29 11:10:41
问题 I'm using canvas to display some sprites, and I need to flip one horizontally (so it faces left or right). I can't see any method to do that with drawImage , however. Here's my relevant code: this.idleSprite = new Image(); this.idleSprite.src = "/game/images/idleSprite.png"; this.idleSprite.frameWidth = 28; this.idleSprite.frameHeight = 40; this.idleSprite.frames = 12; this.idleSprite.frameCount = 0; this.draw = function() { if(this.state == "idle") { c.drawImage(this.idleSprite, this

how to flip a pixmap to draw to a texture in libgdx?

不想你离开。 提交于 2019-11-29 09:45:24
So what I'm trying to do is to generate a background image for my game by drawing pixmaps to a texture. So far I can do that, but now I need to draw the pixmaps flipped in the X or Y axis to the texture. However I can't find anything to do so. The pixmap class does not provide that functionality. Then I thought I could draw a flipped texture region to a texture, but so far I haven't found how to do so. So I was wondering how can I do such a thing, would it be possible to flip a png image with other java libraries and then create a pixmap from that flipped image? I also don't see other option

假如想象 提交于 2019-11-29 08:44:49
问题 iPhone / Objective-C On my view a little "hover" view appears after a user clicks on a button on the main view. When the user clicks this subview I want the subview to FlipFromRight to another view (same size). The main view underneath should stay. viewHot and viewCold are the subviews viewMain is the main one. Is this possible? 回答1: Create another empty view in viewMain called viewHover and position it where you want the hover views to show. Then in IB add either viewHot or viewCold (not

UIVIew Flip Vertical Animation

﹥>﹥吖頭↗ 提交于 2019-11-29 05:08:54
Given: [UIView beginAnimations:nil context:nil]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; [UIView setAnimationDuration:.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:card cache:NO]; myPic = [UIImage UIImagenamed: @"mySecondImage.png"]; [UIView commitAnimations];[/CODE] Which animates 'myPic' right to left with a flip. I need to get the same animation, but vertically. Flip from Top or Flip from Bottom. I looked around, no one really had a working model suggested. I tried this, yet, no luck: float duration = .5; CABasicAnimation* animation =

JavaScript Flip Counter

懵懂的女人 提交于 2019-11-28 17:58:01
I would like to include a flip counter on my site, similar to what Apple was using for their 1 billion app countdown . Can anyone get their JavaScript to work standalone? If anyone can provide working code, that would be great. Steve Harrison They're using a combination of CSS and JavaScript. The flip animation is powered by a CSS Sprite -like technique. First of all, they have a very tall image called filmstrip.png that contains every flip "state" for each number (0 to 9; have a look at a scaled-down detail and you'll see what I mean). Then, in the HTML, each digit is made up of three nested

Displaying card flip animation on old android

有些话、适合烂在心里 提交于 2019-11-28 17:33:04
We all know this article of how to create "card filp" animations using new api . But how can I make this on apis < 3.0 ? Update: As long as there is good and easy-to-use libraries like android-FlipView I don't think you really need to go through such hard ways ... Found the answer. If you want to do flip animation on ALL ANDROID VERSIONS , use this: Activity layout file: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/main_activity_root" android:layout_width="fill_parent" android:layout_height="fill

How to flip UIImage horizontally with Swift?

妖精的绣舞 提交于 2019-11-28 17:03:24
The solution to do UIImage flipping is with the Objective-C code: [UIImage imageWithCGImage:img.CGImage scale:1.0 orientation: UIImageOrientationDownMirrored] However, imageWithCGImage is not available in Swift! Is there a solution for flipping image horizontally with Swift? Thanks! Most factory methods are converted to initializers in swift. Whenever available, even if the class method is still available, they are preferred. You can use: init(CGImage cgImage: CGImage!, scale: CGFloat, orientation: UIImageOrientation) The usage would look like this: var image = UIImage(CGImage: img.CGImage,

What is the purpose of ByteBuffer's flip method? (And why is it called “flip”?)

孤街浪徒 提交于 2019-11-28 15:27:15
问题 Why does ByteBuffer's flip() method called "flip"? What is "flipped" here? According to apidoc, two successive flips won't restore original state, and multiple flips will probably tend limit() to become zero. Can I "unflip" somehow to reuse bytes went out of a limit? Can I concatenate tail to be flipped with some other data? 回答1: One fairly common use case for the ByteBuffer is to construct some data structure piece-by-piece and then write that whole structure to disk. flip is used to flip
