//this class should exist somewhere in your project public class WireArcExample : MonoBehaviour { public float shieldArea;

// ...other code... }

// Create a 180 degrees wire arc with a ScaleValueHandle attached to the disc // that lets you modify the "shieldArea" var in the WireArcExample.js [CustomEditor(typeof(WireArcExample))] public class DrawWireArc : Editor { void OnSceneGUI() { Handles.color = Color.red; WireArcExample myObj = (WireArcExample)target; Handles.DrawWireArc(myObj.transform.position, myObj.transform.up, -myObj.transform.right, 180, myObj.shieldArea); myObj.shieldArea = (float)Handles.ScaleValueHandle(myObj.shieldArea, myObj.transform.position + myObj.transform.forward * myObj.shieldArea, myObj.transform.rotation, 1, Handles.ConeCap, 1); } }

And the script attached to this Handle:
