這個奇怪的抖動爲什麼會發生？

Question

我有一個場景，玩家可以拾取和丟棄物體，以及移動和環視。

所有的球員對象是一個空的遊戲對象「MainCharacter」的孩子：

MainCharacter > 
    Capsule (With RigidBody and PlayerMoveScript) > 
     PlayerBase (empty - used for checking if grounded) 
     MainCamera > 
      Hands(With PickUpDrop script) 

我拿起Lerps我的手的位置，目的不過我的膠囊與任何牆壁相撞後有一個奇怪的抖動，其我無法弄清楚如何修復！

下面是腳本：

拿起並刪除腳本：

public bool handsFull = false; 

    public float distanceMax = 20f; 

    public Transform handPosition; 

    public LayerMask canPickUp; 

    public GameObject taggedGameObject; 

    public bool colliderTriggered; 

    public bool bounds; 

    public PickedUpObject pickedUpScript; 

    public Rigidbody player; 

    // Use this for initialization 
    void Start() { 

     print(FindClosestPickup().name); 
     handPosition = transform; 
     pickedUpScript = null; 

    } 

    // Update is called once per frame 
    void Update() { 


       if (Input.GetKeyDown (KeyCode.E) && !bounds) { 
         if (Physics.CheckSphere (handPosition.position, 2f, canPickUp)) { 

           if (handsFull) { 
             Drop(); 
           } 

           if (!handsFull) { 
             PickedUp(); 
           } 

       handsFull = !handsFull; 

         } 
       } 

       if (handsFull) { 
         RotateMovePickedUpObject(); 
       } 


     } 



    private void PickedUp(){ 

     //Closest object to top of list 
     taggedGameObject = (GameObject)FindClosestPickup(); 

     taggedGameObject.collider.isTrigger = true; 



     taggedGameObject.rigidbody.useGravity = false; 
     taggedGameObject.rigidbody.isKinematic = true; 

     pickedUpScript = taggedGameObject.GetComponent<PickedUpObject>(); 

     Debug.Log ("Pick Up"); 


    } 

    private void RotateMovePickedUpObject(){ 

     //Rotate 

     if(Input.GetKeyDown(KeyCode.End)){ 
      taggedGameObject.transform.localRotation *= Quaternion.Euler(0, 0, 45); 
     } 
     if(Input.GetKeyDown(KeyCode.Delete)){ 
      taggedGameObject.transform.localRotation *= Quaternion.Euler(0, 45, 0); 
     } 
     if(Input.GetKeyDown(KeyCode.PageDown)){

     } 
     if(Input.GetKeyDown(KeyCode.Insert)){

     } 

     taggedGameObject.transform.position = Vector3.Lerp(taggedGameObject.transform.position, handPosition.position, (1 - Mathf.Exp(-20 * Time.smoothDeltaTime)) * 10); 

    } 


    private void Drop(){ 

     taggedGameObject.collider.isTrigger = false; 

     taggedGameObject.rigidbody.useGravity = true; 
     taggedGameObject.rigidbody.isKinematic = false; 

     taggedGameObject = null; 

     Debug.Log ("Drop"); 

     pickedUpScript = null; 

    } 

    private GameObject FindClosestPickup() { 

     //Find closest gameobject with tag 
     GameObject[] gos; 
     gos = GameObject.FindGameObjectsWithTag("pickup"); 
     GameObject closest = null; 
     float distance = Mathf.Infinity; 
     Vector3 position = transform.position; 

     foreach (GameObject go in gos) { 
      Vector3 diff = go.transform.position - position; 
      float curDistance = diff.sqrMagnitude; 
      if (curDistance < distance) { 
       closest = go; 
       distance = curDistance; 
      } 
     } 

     return closest; 
    } 

} 

拾取對象腳本：

public PickUpDrop pickUpScript; 
    public GameObject thisOne; 
    public Color thecolor; 
    public bool inObject; 

    // Use this for initialization 
    void Start() { 
     thisOne = this.gameObject; 
    } 

    // Update is called once per frame 
    void Update() 
    { 
     thecolor = thisOne.renderer.material.color; 

    if (pickUpScript.taggedGameObject != thisOne) 
     { 
      gameObject.renderer.material.color = Color.gray; 
     } 

    if (pickUpScript.taggedGameObject == thisOne) 
     { 
      Color color = renderer.material.color; 
      color.a = 0.5f; 
      renderer.material.color = color; 
     } 
    } 

    void OnTriggerEnter() 
    { 
     if (thisOne == pickUpScript.taggedGameObject) 
     { 
      inObject = true; 
      pickUpScript.bounds = true; 
      gameObject.renderer.material.color = Color.red; 

     } 
    } 

    void OnTriggerExit() 
    { 
     if(thisOne == pickUpScript.taggedGameObject) 
     { 
      inObject = false; 
      pickUpScript.bounds = false; 
      gameObject.renderer.material.color = Color.gray;   
     } 
    } 

} 

Answer 1

taggedGameObject.transform.position = Vector3.Lerp(taggedGameObject.transform.position, handPosition.position, (1 - Mathf.Exp(-20 * Time.smoothDeltaTime)) * 10); 

這條線將繼續向着手的位置移動物體。如果您正在移動遊戲物體的剛體，那麼在物理計算過程中作用於該物體的物理將與更新功能期間物體的手動移動發生衝突。

這取決於您在發生衝突時想要發生什麼情況。如果你只是想讓'抖動'停止並且仍然能夠將物體與其他物理物體對準，那就使用它;

taggedGameObject.rigidbody.AddForce((taggedGameObject.transform.position - handPosition.position) * force); 

這將保持與剛體的所有相互作用。您必須調整移動物體的力量，並且可能會在標記的遊戲對象處於玩家手中時禁用重力。但它應該有預期的效果。
