Handles.DrawWireDisc

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

Parameters

NameDescription
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;
