Description

Draw a solid flat disc in 3D space.


Solid Disc in the Scene View.

// Create a semi transparent white disc with a ScaleValueHandle attached to the disc
// that lets you modify the "areaOfEffect" var in the WireDiscExample.js

@CustomEditor (SolidDiscExample) class DrawSolidDisc extends Editor { function OnSceneGUI () { Handles.color = Color(1,0,0,0.1); Handles.DrawSolidDisc(target.transform.position, Vector3.up, target.areaOfEffect); Handles.color = Color.red; 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:

//SolidDiscExample.js

var areaOfEffect : float = 5;
