I want to execute performDrop() as soon as my finger is over a "droppable Area" which can be detected by using dropEntered(), without lifting the finger from the screen.

Is there any way to achieve this?

So I am working working on something in unity (2d game). I have a list of button (UI) on my scene and I want to implement a scrolling mechanism. What is the best way to go about it? Currently , I can scroll through horizontally because I have added a "scroll rect" to the the canvas holding the buttons as I start the game. However when I try to scroll back (horizontally, it goes beyond the Buttons. Is there a way to make the scrolling continuous such that as I scroll, from the first UI element when I get to the last one and I keep scrolling, it continues with the first element. or what should I do. please let me Know If i should clarify.
In the Scroll rect you can set the movement type. I don't think the kind of "infinite scroll" you are asking for is available.
For your case, I think that the Use Elastic or Clamped mode to force the content to remain within the bounds of the Scroll Rect should do the work.
In the case of the infinite scroll specifically needed, you would need to ask for that explicitely and show your attempt for more specific help.
How can I get something very similar to this but in spriteKit ?

I am working on a UI system for a mobile game in Unreal. I have functionality already in place that basically reads in if the player has swiped by basically getting the player's initial touch location and then checking if the player moves their finger a certain pixel distance and then it changes between pages.
I am trying to add a scroll box to the page as I find that not all of my content will fit on the screen. However, now that I have added it to my Widget, my swiping function no longer works. I am assuming this is because the scroll box is consuming the touch event. Is there a way to make it so that the scrolling does not consume the input event?
I had the same problem but unfortunately, I couldn't find how to continue to read touch events.
As a workaround, I created my own scrollbox, so that I could read the finger location while I'm scrolling.
I want to make an endless vertical scrolling layer that gives the impression that the main character is moving upwards. I have been brainstorming on how to achieve this.
My issue is that I want objects to appear as if they are coming from above and below the screen at the same time. Secondly, I want to be able to move the main character to create and destroy box2d joints between it and some of the objects appearing on the screen. What is the best way to achieve this with consuming too much memory? I would appreciate any help on this.
Apple did a wonderful tutorial of this in a WWDC 2011 video session. It was "UITableView Changes, Tips & Tricks" and it's about 35m40sec into the video.
Since the use of the UITableView is really just a UIScrollView for the purposes of the background, you could just use a UIScrollView and you can either have it move on timer or events as needed.
Think of your player as moving within a stationary bounding box. The background can scroll using the aforementioned pooling method (as the background tile scrolls off the screen it is placed into a pool, and before a new tile is instantiated the pool is checked for available reusable tiles). Thirdly, your enemy objects will simply approach from either the bottom of the screen or the top.
Imagine your idea without the scrolling background (flying effect) and you should find that the problem is relatively straightforward.
I also needed and endless scrolling background layer. This can do exactly that, and it is super simple to set up and use. Just copy the four files in to the cocos2d folder in your project, then follow the quick tutorial seen on the github. Make sure the image you use is seamless (when you line them up vertically you can't tell where one ends.
I have a graphic that is 3 times the width of an iphone landscape view.
I am trying to auto scroll it so that it appears that it is moving sideways, without using the touchscreen scrolling method.
My aim is to maybe have a button you can press and it moves it left or right across the screen like an animation.
I can deal with everything else but am having trouble finding a solution.
Any example code would be appreciated or even any info on whether it is possible or not.
Thanks. Dave
You can wrap a UIView in an animation block. The animation sweeps the origin value in its frame property from one point to another, over a set period of time.
