Handles.DrawWireDisc

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

Parameters

centerThe center of the dics.
normalThe normal of the disc.
radiusThe 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;
