| text | Text to display on the label. |
| image | Texture to display on the label. |
| content | Text, image and tooltip for this label. |
| style | The style to use. If left out, the label style from the current GUISkin is used.Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles. |
Description
Make a text label positioned in 3D space.
Labels have no user interaction, do not catch mouse clicks and are always rendered in normal style. 
Label in the Scene View.
To use this example, save this script in the Assets/Editor folder:
using UnityEngine; using UnityEditor;
[CustomEditor( typeof( DrawWireArc ) )] public class DrawWireArcEditor : Editor { void OnSceneGUI( ) { DrawWireArc t = target as DrawWireArc;
Handles.color = Color.blue; Handles.Label( t.transform.position + Vector3.up * 2, t.transform.position.ToString( ) + "\nShieldArea: " + t.shieldArea.ToString( ) );
Handles.BeginGUI( ); GUILayout.BeginArea( new Rect( Screen.width - 100, Screen.height - 80, 90, 50 ) );
if( GUILayout.Button( "Reset Area" ) ) t.shieldArea = 5;
GUILayout.EndArea( ); Handles.EndGUI( );
Handles.color = new Color( 1, 1, 1, 0.2f ); Handles.DrawWireArc( t.transform.position, t.transform.up, -t.transform.right, 180, t.shieldArea );
Handles.color = Color.white; t.shieldArea = Handles.ScaleValueHandle( t.shieldArea, t.transform.position + t.transform.forward * t.shieldArea, t.transform.rotation, 1, Handles.ConeCap, 1 ); } }
...and place this script on a GameObject:
using UnityEngine;
[ExecuteInEditMode] public class DrawWireArc : MonoBehaviour { public float shieldArea = 5; }
