Optimized ScrollView Adapter

Display large amounts of data efficiently through a List, Grid or Table, on any device!

Until quantum computers become mainstream, we need to optimize our ScrollViews!

Even if speed is not a concern for you, OSA still provides a plethora of shiny features, making it the ultimate replacement of Unity's built-in Scroll View.

Create your own customized implementation or get started in just 1 minute via OSA wizard and continue expanding according to your needs, guided by the provided demos.

Technical details

Highlights

• Works on any device

• Can handle 2 billion items (int.MaxValue-1)

• Variable data set

• Items can have different sizes

• Support for Content Size Fitter for items with unknown initial size

• TableView to allow displaying/modifying values from table-like data

• GridView with fixed or auto-adaptable number rows/columns

• Vertical/horizontal orientation and optional spacing/padding

• Custom rotation and scaling, including that of any CanvasScaler

• Configurable snapping

• Responsive to changes in viewport's size

• Multiple item types

• Change item size in real time (ex. animations), even if it's not visible

• Infinite looping, optional

• Smoothly scroll to a specific item

• Extensible source code provided

• Partially customizable recycling policy through provided callbacks

• Enhanced scrollbar functionalities via ScrollbarFixer, which adds auto-hide/hide-when-not-needed animations

• Dragging the items within the list(re-ordering), between 2 lists (transferring) or outside (orphaning)

• Scrolling speed can optionally accelerate with each subsequent drag to navigate faster within the list on demand

Goodies

• LazyList data structure optimized for large amounts of data

• AsyncBufferredDataSource class to aid in scenarios where data isn't readily available

• Content background scrolling effect, with optional parallax effect

• Gallery effect - middle items bigger than side items, or custom, including changes in rotation

• Nested ScrollViews are supported out of the box (disabled by default, for performance), including nesting a regular ScrollRect as parent/child

• Simple ExpandCollapseOnClick utility script in the example scenes that can be used to expand/shrink items on click

• Supports all Canvas spaces

• PullToRefresh-PullToLoadMore utility script

• DateTime picker pop-up utility which can be used from anywhere (one line of code)

• RemoteImageBehavior - a full solution for downloading images with caching support and adaptive queue management

• PackedGridLayout - a self-contained script for arranging items of different sizes in a given amount of space as efficiently as possible

Playmaker support

• At least Unity 2017.1 needed

• Lists, grids, date-time picker, content size fitter(items of variable sizes), large data sets.

• The demo scenes included do not have Playmaker-counterparts, though this may change in the future. Please watch the tutorial to see how to create Playmaker-ready OSAs through the OSA wizard instead
