Quaternion.LookRotation角度不能正常工作

Question

我一直在嘗試一段時間，並找不出爲什麼它不工作。 我有一個PathHolder父項中的空對象的簡單路徑，它跟隨該路徑並順利旋轉以面對它將要前進的點。我的問題是，有一半的時間，角色對象並沒有一直旋轉，而是仍然朝着應有的方向前進。 另一個奇怪的是，將點移近會減少物體的旋轉量，並且進一步移動它會使角色面對點。但是，在任何情況下工作路徑都需要靈活，所以我不能讓距離影響旋轉。

理想情況下，我希望角色可以完全順暢地朝向箭頭鍵按下的位置旋轉，以便角色在玩家釋放按鍵時不會卡在遊戲中途。這裏是我的代碼至今：

using UnityEngine; 
using System.Collections; 

public class CharacterControllerPath : MonoBehaviour 
{ 
    enum Direction {Forward, Backward}; 
    Direction charDirection; 

    public PathEditor pathToFollow; 

    private Vector3 targetPosition; 

    public string pathName; 
    public int wayPointID = 0; 
    public float speed; 
    public float rotationSpeed = 7.0f; 

    private float reachDistance = 1.0f; 
    private float distanceX; 
    private float distanceY; 

    void Start() 
    { 
     transform.position = new Vector3(pathToFollow.pathObj[wayPointID].transform.position.x, transform.position.y, pathToFollow.pathObj[wayPointID].transform.position.z); 
     charDirection = Direction.Forward; 
     Vector3 targetPosition = new Vector3(pathToFollow.pathObj[wayPointID + 1].transform.position.x, transform.position.y, pathToFollow.pathObj[wayPointID + 1].transform.position.z); 
     transform.LookAt(targetPosition); 
    } 

    void FixedUpdate() 
    { 
     Movement(); 
    } 

    void Movement() 
    { 
     if(Input.GetKey(KeyCode.RightArrow)) 
     { 
      charDirection = Direction.Forward; 

      //Move 
      targetPosition = new Vector3(pathToFollow.pathObj[wayPointID].transform.position.x, transform.position.y, pathToFollow.pathObj[wayPointID].transform.position.z); 
      transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime); 

      //Rotate 
      targetPosition = new Vector3(pathToFollow.pathObj[wayPointID].transform.position.x, 0, pathToFollow.pathObj[wayPointID].transform.position.z); 
      var rotation = Quaternion.LookRotation(targetPosition); 
      transform.rotation = Quaternion.Slerp(transform.rotation, rotation, speed * Time.deltaTime); 

      if(transform.position.x == targetPosition.x && transform.position.z == targetPosition.z) 
       wayPointID++; 
     } 
     else if(Input.GetKey(KeyCode.LeftArrow)) 
     { 
      charDirection = Direction.Backward; 

      //Move 
      targetPosition = new Vector3(pathToFollow.pathObj[wayPointID - 1].transform.position.x, transform.position.y, pathToFollow.pathObj[wayPointID - 1].transform.position.z); 
      transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime); 

      //Rotate 
      targetPosition = new Vector3(pathToFollow.pathObj[wayPointID - 1].transform.position.x, 0, pathToFollow.pathObj[wayPointID - 1].transform.position.z); 
      var rotation = Quaternion.LookRotation(targetPosition); 
      transform.rotation = Quaternion.Slerp(transform.rotation, rotation, speed * Time.deltaTime); 

      if(transform.position.x == targetPosition.x && transform.position.z == targetPosition.z) 
       wayPointID--; 
     } 

     if(wayPointID >= pathToFollow.pathObj.Count) 
     { 
      //Put code to finish the level 
      wayPointID = (pathToFollow.pathObj.Count - 1); 
     } 
     else if(wayPointID <= 0) 
      wayPointID = 0; 
    } 
} 

Answer 1

如果你想兩個向量之間平滑移動載體，應用

Vector3.Lerp(firstPosOrRotation, secondPosOrRotation, Time.deltaTime*Input.GetInputRaw("Horizontal")*speed); 

Input.GetInputRaw（「水平」）只是之間的值 - 1和1取決於正在按下的方向鍵。 現在只需獲取路徑中的每個點和下一個點以及它們之間的Lerp。

• 編輯 對於旋轉，代替Time.deltaTime和所有，爲此

  旋轉= Vector3.Lerp（rotationA，rotationB，Mathf.Clamp（DIST（POS， finalPos）， 0，1）;

  DIST（POS， finalPos）=量在點A和B之間行進

我希望這是清楚的烯ough， 我不確定你的意思，或者你希望對象在路徑上向前。
