Parameters
| 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;
