オブジェクトをマウスクリニックで別のオブジェクトと移動およびスワップする方法

Question

これまでのところ、オブジェクトをマウスクリックで少し移動させるスクリプトがありますが、私はそれを変更してこのオブジェクトをクリックすると、現在移動している小さな距離ではなく、隣にある別のオブジェクトと場所が入れ替わります。私はこのことをどうやって行うのか少し混乱している。

using UnityEngine; 
using System.Collections; 

public class NewBehaviourScript: MonoBehaviour 
{ 
    public float movementSpeed = 10; 

    void Update(){ 
     if (Input.GetMouseButtonDown(0)) 
     { 
      transform.Translate(Vector3.right * movementSpeed * Time.deltaTime); 
     } 


    } 
} 

Answer 1

これを試してみてください：

using UnityEngine; 
using System.Collections; 

public class NewBehaviourScript: MonoBehaviour { 
    public GameObject objectA; //Needs to be initialized in the editor, or on Start 
    public GameObject objectB; //Needs to be initialized in the editor, or on Start 
    public float movementSpeed = 10; 
    private Vector3 posA = Vector3.zero; //Vector3.zero is for initialization 
    private Vector3 posB = Vector3.zero; //Vector3.zero is for initialization 

    void Update() { 
     if (Input.GetMouseButtonDown(0)) { 
      posA = objectA.gameObject.transform.position; 
      posB = objectB.gameObject.transform.position; 
      objectA.gameObject.transform.position = posB; 
      objectB.gameObject.transform.position = posA; 
     } 
    } 

} 

これは単なるポサとPOSB変数に各オブジェクトの位置を保存し、その後、POSAにPOSBとをObjectBにObjectAに移動します。今

-OR-

ObjectBには常に別のオブジェクト（定数NOT）であり、あなたが最も近いオブジェクトを検索する方法がわからない場合、あなたはレイキャストを使用することができます。あなたのコードに次の関数を追加します

gamObject NearestObject() { 
    int dist; 
    int nearestIndex; 
    //Create an array to contain objects to be hit by the raycast 
    RaycastHit[] nearby; 
    //Hit all objects within 100 units with a raycast, change the 100 as needed 
    nearby = Physics.RaycastAll(objectA.transform.position, transform.forward, 100.0f); 
    //Check if there is at least one object 
    if(nearby.Length > 0) { 
     //If there is only one object and it's not objectA 
     if(!(nearby.Length == 1 && nearby[0].transform == objectA.transform)) { 
      dist = nearby[0].distance; 
      nearestIndex = 0; 
      for (int i = 1; i < nearby.Length; i++) { 
       if(nearby[i].transform != gameObject.transform && nearby[i].distance < dist) 
        dist = nearby[i].distance; 
        nearestIndex = i; 
       } 
      } 
     } else { 
      //There is only one object in the raycast and it is objectA 
      nearestIndex = -1; 
     } 
    } else { 
     //There are no objects nearby 
     nearestIndex = -1; 
    } 
    //nearestIndex will only be negative one if there are no objects near objectA, so return null 
    if (nearestIndex == -1) { 
     return null; 
    } else { 
     //return nearest object to update 
     return nearby[nearestIndex].gameObject; 
    } 
} 

最後に、変更のアップデートに：

 void Update() { 
     if (Input.GetMouseButtonDown(0)) { 
      objectB = NearestObject(); 
      if (objectB != null) { 
       posA = objectA.gameObject.transform.position; 
       posB = objectB.gameObject.transform.position; 
       objectA.gameObject.transform.position = posB; 
       objectB.gameObject.transform.position = posA; 
      } 
     } 
    }

using UnityEngine; 
using System.Collections; 

public class NewBehaviourScript : MonoBehaviour 
{ 
    //making them public just to be able watch values change in game mode 
    public float movementSpeed = 10; 
    public GameObject g1; 
    public GameObject g2; 
    public Vector3 vec1; 
    public Vector3 vec2 = new Vector3(2F, 2F, 2F); 
    public bool swapBack = false; 

    void Start() 
    { 
     g1 = GameObject.Find("Cube"); 
     g2 = GameObject.Find("Sphere"); 
     vec1 = new Vector3(g1.gameObject.transform.position.x, g1.gameObject.transform.position.y, g1.gameObject.transform.position.z); 
     vec2 = new Vector3(g2.gameObject.transform.position.x, g2.gameObject.transform.position.y, g2.gameObject.transform.position.z); 
    } 

    void Update() 
    { 
     if (Input.GetMouseButtonDown(0)) 
     { 
      transform.Translate(Vector3.right * movementSpeed * Time.deltaTime); 
      swap(swapBack); 
     } 
    } 

    public void swap(bool back) 
    { 
     if (back) 
     { 
      g1.transform.position = vec1; 
      g2.transform.position = vec2; 
      swapBack = false; 
     } 
     else 
     { 
      g1.transform.position = vec2; 
      g2.transform.position = vec1; 
      swapBack = true; 
     } 
    } 
}
