Description

Make a vertical scrollbar. Scrollbars are what you use to scroll through a document. Most likely, you want to use scrollViews instead.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { public float vSbarValue;

void OnGUI() { vSbarValue = GUI.VerticalScrollbar(new Rect(25, 25, 100, 30), vSbarValue, 1.0F, 10.0F, 0.0F); } }

Finding extra elements:

The styles of the buttons at the end of the scrollbar are searched for in the current skin by adding "upbutton" and "downbutton" to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending "thumb" to the style name.

// This will use the following style names to determine the size / placement of the buttons
// MyVertScrollbarupbutton   - Name of style used for the up button.
// MyVertScrollbardownbutton - Name of style used for the down button.
// MyVertScrollbarthumb      - Name of style used for the draggable thumb.

using UnityEngine; using System.Collections;

public class ExampleClass : MonoBehaviour { public float scrollPos = 0.5f;

void OnGUI() { scrollPos = GUI.VerticalScrollbar(new Rect(0, 0, 100, 20), scrollPos, 1, 0, 100, "Scroll"); } }
