You should use UIScrollView component. It is used together with UIPanel
to provide scrollable, clipped content. Usually it is used also with UIGrid
or UITable
, to provide functionality of scrolled table.
However in your case you should just create all your Credits content as a child of this UIScrollView. If you want, you can add another GameObject
with UIScrollBar
to provide scroll bar functionality.
If you take a closer look on imported NGUI
package, you will find various Example scenes, where such functionality is used. Also this official tutorial may help: UIScrollView tutorial.
