Handles.EndGUI

Description

End a 2D GUI block and get back to the 3D handle GUI.

GUI in the Scene view.

See Also: Handles.BeginGUI.

To use this example, save this script in the Assets/Editor folder:

#pragma strict
@CustomEditor(DrawWireArc)
public class DrawWireArcEditor extends Editor {
	function OnSceneGUI() {
		var t: DrawWireArc = 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);
	}
}

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 to demonstrate how to use Handles.BeginGui and Handles.EndGUI to display a GUIButton controlling the area of an arc:

#pragma strict
@ExecuteInEditMode
public class DrawWireArc extends MonoBehaviour {
	public var shieldArea: float = 5;
}

using UnityEngine;

[ExecuteInEditMode]
public class DrawWireArc : MonoBehaviour
{
	public float shieldArea = 5;
}
