Overview

This folder collects several scroll-snap demonstrations across multiple scenes, covering paged horizontal and vertical snapping, content-item snapping, infinite/looping snaps, pagination, and runtime page management. Use it when you need swipeable paged UI, carousels, or snapping lists with button- and pagination-driven navigation.

Controls Featured

• Horizontal Scroll Snap — paged horizontal snapping driven by swipes, buttons, and page jumps, including dynamic add/remove of pages.
• Vertical Scroll Snap — the vertical equivalent, with pages added, removed, and jumped to at runtime.
• Content Scroll Snap Horizontal — snaps content items to the centre of the scroll rect rather than paging whole screens.
• Infinite Scroll Snap — endlessly looping scroll-snap content (deprecated for Unity 6, shown for legacy reference).

Scene Setup

1. Add the UI Extensions Samples sample to your project (open the package in the Unity Package Manager and import UI Extensions Samples), or copy Examples~/HSS-VSS-ScrollSnap/ into your project’s Assets/ folder.
2. Open one of the example scenes in that folder, for example ContentSnapScrollExample, InfiniteScrollSnapExamples, FullScreenScrollSnap, PaginationManagerExample, ScrollSnapDynamic, InfiniteMagneticExample, or ScrollSnapManagedTests.
3. Press Play.

What to Expect

Each scene shows a different scroll-snap variant. Paged scenes let you swipe or use buttons to move between full-screen pages, and a pagination row of dots reflects and controls the current page. The content-snap scene snaps individual child items to the centre rather than moving whole screens. The dynamic/managed scenes demonstrate adding pages, removing the current or all pages, and jumping to a page entered into an input field at runtime; one scene also adds ten pages to a freshly instantiated scroll snap when you press the K key. Page-change, start, and end events are logged to the console as you navigate.

Key Code Patterns

A pagination button routes a click straight to the scroll snap’s GoToScreen to jump to a specific page:

public class PaginationScript : MonoBehaviour, IPointerClickHandler
{
    public HorizontalScrollSnap hss;
    public int Page;

    public void OnPointerClick(PointerEventData eventData)
    {
        if (hss != null)
        {
            hss.GoToScreen(Page);
        }
    }
}

Pages can also be added, removed, or jumped to at runtime against either a horizontal or vertical snap:

public void AddButton()
{
    if (HSS)
    {
        var newHSSPage = GameObject.Instantiate(HorizontalPagePrefab);
        HSS.AddChild(newHSSPage);
    }
    // ...
}

public void JumpToPage()
{
    int jumpPage = int.Parse(JumpPage.text);
    if (HSS) { HSS.GoToScreen(jumpPage); }
    if (VSS) { VSS.GoToScreen(jumpPage); }
}
