Handles.DrawWireDisc

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

Parameters

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

Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

Description

Draw the outline of a flat disc in 3D space.


Wire Disc in the Scene View.

	// Create a wire disc with a ScaleValueHandle attached to the disc
	// that lets you drag the "areaOfEffect" var in the WireDiscExample.js
	
	@CustomEditor (WireDiscExample)
	class DrawWireDisc extends Editor {
	    function OnSceneGUI () {
	    	Handles.color = Color.red;
	        Handles.DrawWireDisc(target.transform.position, Vector3.up, target.areaOfEffect);
	        
	        target.areaOfEffect =
			Handles.ScaleValueHandle(target.areaOfEffect,
						target.transform.position + Vector3(target.areaOfEffect,0,0),
						Quaternion.identity,
						2,
						Handles.CylinderCap,
						2);
	    }
	}

And the script attached to this Handle:

	//WireDiscExample.js
	
	var areaOfEffect : float = 5;
