SKNode scale from the touched point

由 可紊 提交于 2019-11-27 01:58:39
问题 I have added UIPinchGestureRecognizer to my scene.view to scale my content. I actually scale the parent node where all my visible contents reside. But I have problem though with scaling point. The thing is node scale from the lower-left corner. It's definitely not what I want. Do I have to write lots of code to be able to scale from the point where pinching occurs? Could you please give some hints as to what way to follow. 回答1: I have been working on the same problem and my solution is shown

由 与世无争的帅哥 提交于 2019-11-26 20:28:16
问题 I'm using storyboard (iOS 6.0) to create a photo gallery viewer for my app. This is how my imageViewController is set up in storyboard: I've made sure to enable userInteraction and multiple touches on both the imageView and scrollView. What I want to do is, on pinch I want to zoom into the imageView (maximum scale 3) and be able to pan around. This is what I currently have, however, even though the pinch gesture is detected the scale does not change. - (IBAction)imagePinched:(id)sender { if

问题 I am trying to implement pinch zoom and drag using Android's gesture listener and scale listener. The problem is that when I perform pinch zoom, the image (which I am trying to zoom) bounces to a particular location. Also the zoom position is not centered. The following code demonstrates what I am trying to achieve. Any idea why the image is jumping (and how to correct it) ? public class CustomView extends View { Bitmap image; int screenHeight; int screenWidth; Paint paint; GestureDetector
