Description
Make a horizontal scrollbar.
A scrollbar control returns a float value that represents the position of the draggable "thumb" withtin the bar. You can use the value to adjust another GUI element to reflect the scroll position. However, most scrollable views can be handled more easily using a scroll view control.
Horizontal Scrollbar in the Game View.
using UnityEngine;
public class ExampleScript : MonoBehaviour { float hSbarValue;
void OnGUI() { hSbarValue = GUILayout.HorizontalScrollbar(hSbarValue, 1.0f, 0.0f, 10.0f); GUILayout.Label("This is a text that makes space"); } }
The styles of the scroll buttons at the end of the bar can be located in the current skin by adding "leftbutton" and "rightbutton" to the style name. The name of the scrollbar thumb (the thing you drag) is found by appending "thumb" to the style name.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public float scrollPos = 0.5F; // This will use the following style names to determine the size / placement of the buttons // MyScrollbarleftbutton - Name of style used for the left button. // MyScrollbarrightbutton - Name of style used for the right button. // MyScrollbarthumb - Name of style used for the draggable thumb. void OnGUI() { scrollPos = GUILayout.HorizontalScrollbar(scrollPos, 1, 0, 100, "MyScrollbar"); } }
