Handles.DrawWireDisc

Parameters

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;
