Physics.SphereCast problem? center of SphereCast different from center of its transform

Anyone has expererienced this problem with Physics.SphereCast? I mean, it seems that the center of SphereCast is different from the center of its transform.

if you add a sphere collider to a game object and try this code the behaviour is not the expected behavior (SphereCast doesn't return true when you expect, its like the spherecast is shifted):

using UnityEngine;

public class test : MonoBehaviour {

public bool onGroundDown=false; public bool onGroundLat=false; public bool onGroundFront=false; public SphereCollider sphereCollider; RaycastHit hitdown; RaycastHit hitlat; RaycastHit hitfront;

void FixedUpdate(){ onGroundDown=Physics.SphereCast(transform.position, sphereCollider.radius, -transform.up , out hitdown , sphereCollider.radius); onGroundLat=Physics.SphereCast(transform.position, sphereCollider.radius, -transform.right , out hitlat, sphereCollider.radius); onGroundFront=Physics.SphereCast(transform.position, sphereCollider.radius, -transform.forward , out hitfront , sphereCollider.radius); } }

instead with this code it works like expected:

using UnityEngine;

public class test : MonoBehaviour {

public bool onGroundDown=false; public bool onGroundLat=false; public bool onGroundFront=false; public SphereCollider sphereCollider; RaycastHit hitdown; RaycastHit hitlat; RaycastHit hitfront;

void FixedUpdate(){ Vector3 sphereCenter=new Vector3(transform.position.x+sphereCollider.radius,transform.position.y+sphereCollider.radius,transform.position.z+sphereCollider.radius);

onGroundDown=Physics.SphereCast(sphereCenter, sphereCollider.radius, -transform.up , out hitdown , sphereCollider.radius); onGroundLat=Physics.SphereCast(sphereCenter, sphereCollider.radius, -transform.right , out hitlat, sphereCollider.radius); onGroundFront=Physics.SphereCast(sphereCenter, sphereCollider.radius, -transform.forward , out hitfront , sphereCollider.radius); } }

Is this behavior wanted or is an error of SphereCast?

UPDATE 11/05/10 IS it possible that anybody can help me with this problem? Its a week that this question is still open.
