Handles.DrawSolidArc

static function DrawSolidArc (center : Vector3, normal : Vector3, from : Vector3, angle : float, radius : float) : void

Parameters

Name	Description
center	the center of the circle
normal	the normal of the circle
from	the direction of the point on the circumference, relative to the center, where the sector begins
angle	the angle of the sector, in degrees
radius	the radius of the circle Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

Description

Draw a circular sector (pie piece) in 3D space.

Solid 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 (SolidArcExample)
class DrawSolidArc extends Editor {
function OnSceneGUI () {
Handles.color = Color(1,1,1,0.2);
Handles.DrawSolidArc(target.transform.position,
target.transform.up,
-target.transform.right,
180,
target.shieldArea);
Handles.color = Color.white;
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:

// SolidArcExample.js

var shieldArea : float = 5;
