Description

Begin a scrolling view inside your GUI.

ScrollViews let you make a smaller area on-screen look 'into' a much larger area, using scrollbars placed on the sides of the ScrollView.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { // The position on of the scrolling viewport public Vector2 scrollPosition = Vector2.zero;

void OnGUI() { // An absolute-positioned example: We make a scrollview that has a really large client // rect and put it in a small rect on the screen. scrollPosition = GUI.BeginScrollView(new Rect(10, 300, 100, 100), scrollPosition, new Rect(0, 0, 220, 200));

// Make four buttons - one in each corner. The coordinate system is defined // by the last parameter to BeginScrollView. GUI.Button(new Rect(0, 0, 100, 20), "Top-left"); GUI.Button(new Rect(120, 0, 100, 20), "Top-right"); GUI.Button(new Rect(0, 180, 100, 20), "Bottom-left"); GUI.Button(new Rect(120, 180, 100, 20), "Bottom-right");

// End the scroll view that we began above. GUI.EndScrollView(); } }
