public static function DrawSolidDisc(center: Vector3, normal: Vector3, radius: float): void;
public static void DrawSolidDisc(Vector3 center, Vector3 normal, float radius);

Parameters

center The center of the dics.
normal The normal of the disc.
radius The radius of the disc.

Description

Draw a solid flat disc in 3D space.


Solid Disc in the Scene view.

Note: Use HandleUtility.GetHandleSize if you want the handle to always remain the same size on the screen.

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

#pragma strict
@CustomEditor(DrawSolidDisc)
public class DrawSolidDiscEditor extends Editor {
	function OnSceneGUI() {
		var t: DrawSolidDisc = target as DrawSolidDisc;
		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.DrawSolidDisc(t.transform.position, t.transform.up, 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( DrawSolidDisc ) )] public class DrawSolidDiscEditor : Editor { void OnSceneGUI( ) { DrawSolidDisc t = target as DrawSolidDisc;

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.DrawSolidDisc( t.transform.position, t.transform.up, 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 the GameObject where you want the disc to appear:

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

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