オブジェクトのMoveTowardsが新しい位置に到達して回転したことを確認するにはどうすればよいですか？

Question

private void MoveToNewFormation() 
    { 
     squadMembers = GameObject.FindGameObjectsWithTag("Squad Member"); 
     float step = speed * Time.deltaTime; 
     for (int i = 0; i < squadMembers.Length; i++) 
     { 
      squadMembers[i].transform.LookAt(newpos[i]); 
      squadMembers[i].transform.position = Vector3.MoveTowards(squadMembers[i].transform.position, newpos[i], step); 
      //squadMembers[i].transform.rotation = qua[i]; 
     } 
    } 

および更新でそれを呼び出す：

void Update() 
    { 
     if (Input.GetKeyDown(KeyCode.F)) 
     { 
      ChangeFormation(); 
     } 

     if (move == true) 
      MoveToNewFormation(); 
    } 

一度newposに達しsquadMembersの一つは、私は

squadMembers[i].transform.rotation = qua[i]; 

資格が一覧であると私は回転したいをしたいとき彼がnewposに到着したら、チームメンバー。

インサイドMoveToNewFormation私はループの後の行を追加するために考えた：

if (squadMembers[i].transform.position == newpos[i]) 
{ 
    squadMembers[i].transform.rotation = qua[i]; 
} 

をしかし、「私は」が存在しないので、それはループの後です。

public class SquadFormation : MonoBehaviour 
{ 
    enum Formation 
    { 
     Square, Circle, Triangle

    private bool move = false; 

    // Use this for initialization 
    void Start() 
    { 
     formation = Formation.Square; 
     ChangeFormation(); 
    } 

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

     }

      MoveToNewFormation(); 
    }

      case Formation.Circle:

       break; 
     } 
    } 

    private Vector3 FormationSquarePositionCalculation(int index) // call this func for all your objects 
    { 
     float posX = (index % columns) * squareSpace; 
     float posY = (index/columns) * squareSpace; 
     return new Vector3(posX, posY); 
    } 

    private void FormationSquare() 
    {

      go.Rotate(new Vector3(0, -90, 0)); 
      go.tag = "Squad Member"; 
     } 
     formation = Formation.Circle; 
    } 

    private Vector3 FormationCirclePositionCalculation(Vector3 center, float radius, int index, float angleIncrement) 
    { 
     float ang = index * angleIncrement; 
     Vector3 pos; 
     pos.x = center.x + radius * Mathf.Sin(ang * Mathf.Deg2Rad); 
     pos.z = center.z + radius * Mathf.Cos(ang * Mathf.Deg2Rad); 
     pos.y = center.y; 
     return pos; 
    } 

    private void FormationCircle()

      var rot = Quaternion.LookRotation(center - pos); 
      pos.y = Terrain.activeTerrain.SampleHeight(pos); 
      pos.y = pos.y + yOffset; 
      newpos.Add(pos); 
      qua.Add(rot); 
     } 
     move = true; 
     formation = Formation.Square; 
    } 

    private void MoveToNewFormation() 
    { 
     squadMembers = GameObject.FindGameObjectsWithTag("Squad Member"); 
     float step = speed * Time.deltaTime; 
     for (int i = 0; i < squadMembers.Length; i++) 
     {

      squadMembers[i].transform.position = Vector3.MoveTowards(squadMembers[i].transform.position, newpos[i], step); 
      //squadMembers[i].transform.rotation = qua[i];

     //if (squadMembers[i].transform.position == newpos[i])

Answer 1

あなたは、しきい値を使用し、そのしきい値を使用して距離を確認することができます。

これは完全なスクリプトです。 スクリプトの開始時にこのようにしきい値を定義します。

public float threshold = 0.1f; 

次に、このようなMoveToNewFormation（）関数を変更します。

private void MoveToNewFormation() 
{ 
    squadMembers = GameObject.FindGameObjectsWithTag("Squad Member"); 
    float step = speed * Time.deltaTime; 
    for (int i = 0; i < squadMembers.Length; i++) 
    { 
     squadMembers[i].transform.LookAt(newpos[i]); 
     squadMembers[i].transform.position = 
     Vector3.MoveTowards(squadMembers[i].transform.position, newpos[i], step); 
     if(Vector3.Distance(squadMembers[i].transform.position,newpos[i])<threshold){ 
       squadMembers[i].transform.rotation = qua[i]; 
     } 
    } 

    //if (squadMembers[i].transform.position == newpos[i]) 
}
