RadiusHandle(Quaternion, Vector3, float, bool)

Make a Scene view radius handle.
public static float RadiusHandle(Quaternion rotation, Vector3 position, float radius, bool handlesOnly)

Parameters

rotation

The orientation of the handle in 3D space.

position

The center of the handle in 3D space.

radius

Radius to modify.

handlesOnly

Whether to omit the circular outline of the radius and only draw the point handles.

Returns

Type

Description

floatThe new value modified by the user's interaction with the handle. If the user has not moved the handle, it will return the same value as you passed into the function.

Remarks

RadiusHandle (RadiusHandle)
RadiusHandle on the Scene View.
// Name this script "EffectRadiusEditor"using UnityEngine;using UnityEditor;[CustomEditor(typeof(EffectRadius))]public class EffectRadiusEditor : Editor{ public void OnSceneGUI() { EffectRadius t = (target as EffectRadius); EditorGUI.BeginChangeCheck(); float areaOfEffect = Handles.RadiusHandle(Quaternion.identity, t.transform.position, t.areaOfEffect); if (EditorGUI.EndChangeCheck()) { Undo.RecordObject(target, "Changed Area Of Effect"); t.areaOfEffect = areaOfEffect; } }}
And the Script attached to this GameObject:
// Name this script "EffectRadius"using UnityEngine;using System.Collections;public class EffectRadius : MonoBehaviour{ public float areaOfEffect = 1;}
