Description
Draw a circular arc in 3D space.
Wire Arc in the Scene View.
// 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 (WireArcExample) class DrawWireArc extends Editor { function OnSceneGUI () { Handles.color = Color.red; Handles.DrawWireArc(target.transform.position, target.transform.up, -target.transform.right, 180, target.shieldArea); target.shieldArea = Handles.ScaleValueHandle(target.shieldArea, target.transform.position + target.transform.forward*target.shieldArea, target.transform.rotation, 1, Handles.ConeCap, 1); } }
And the script attached to this Handle:
// WireArcExample.js var shieldArea : float = 5;
