触摸控制左右移动立方体（在生成它们的数组中）

Question

我正在移动一个由两个立方体组成的对象：左和右。这些立方体是在 y 轴上随机生成的。

我可以毫无问题地左右移动它们，但是，当我左右移动其中一个立方体时，它们都会移动。

我怎样才能在仅向左或向右触摸而不是全部移动时仅移动其中一个立方体？下面是我的代码：

生成立方体代码：

public Transform block;
public Transform player;
private float objectSpawnedTo = 5.0f;
public static float distanceBetweenObjects = 5.0f;
private float nextCheck = 0.0f;
private ArrayList objects = new ArrayList();
void Start () {
    maintenance(0.0f);
}


void Update () {
    float playerX = player.position.y;
    if(playerX > nextCheck)
    {
        maintenance(playerX);
    }
}

private void maintenance(float playerX)
{
    nextCheck = playerX + 30;
    for (int i = objects.Count-1; i >= 0; i--) 
    {
        Transform blck = (Transform)objects[i];
        if(blck.position.y < (transform.position.y - 30))
        {
            Destroy(blck.gameObject);
            objects.RemoveAt(i);
        }
    }
    spawnObjects(5);
}

private void spawnObjects(int howMany)
{
    float spawnX = objectSpawnedTo;
    for(int i = 0; i<howMany; i++)
    {
        Vector3 pos = new Vector3(-3.5f,spawnX, 0);
        //float firstRandom = Random.Range(-6.0f, 1.0f);
        Transform blck = (Transform)Instantiate(block, pos, Quaternion.identity);
        //blck.localScale+=new Vector3(firstRandom*2,0,0);
        objects.Add(blck);
        //pos = new Vector3(0,spawnX, 0);
        //blck = (Transform)Instantiate(block, pos, Quaternion.identity);
        //blck.localScale +=new Vector3((8.6f-firstRandom)*2,0,0);
        //objects.Add(blck);
        spawnX = spawnX + distanceBetweenObjects;
    }
    objectSpawnedTo = spawnX;
}

}

立方体控制代码：

public float speed = 5;

// Use this for initialization
void Start () {

}

void Update() {
    if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
        // Get movement of the finger since last frame
        Vector3 touchDeltaPosition = Input.GetTouch(0).deltaPosition;

        // Move object across XY plane
        transform.Translate(touchDeltaPosition.x * speed, 0, 0);


        Vector3 boundaryVector = transform.position;   
        boundaryVector.x = Mathf.Clamp (boundaryVector.x, -5.5f, -2.8f);
        transform.position = boundaryVector;
    }
}

}

问题是您的多维数据集控制代码中没有关于选择哪个多维数据集的条件：您只需等待Input.touchCount > 0，然后移动多维数据集。所以所有有这个脚本的立方体都会移动。

我认为你需要做的是一个光线投射来检查哪个立方体被“触摸”，然后只有在光线投射成功时才移动它：

[SerializeField]
private float speed = 0.5f;

private int MAX_TOUCH_COUNT = 5;
private bool[] touched;

protected void Start()
{
    touched = new bool[MAX_TOUCH_COUNT];
}

void Update()
{
    if (Input.touchCount > 0)
    {
        for(int i = 0; i < (Input.touchCount <= MAX_TOUCH_COUNT ? Input.touchCount : MAX_TOUCH_COUNT); i++)
        {
            if(touched[i] && Input.GetTouch(i).phase == TouchPhase.Ended)
            {
                touched[i] = false;
            }
            else if (!touched[i] && Input.GetTouch(i).phase == TouchPhase.Began)
            {
                Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);
                RaycastHit hitInfo;
                if (Physics.Raycast(ray, out hitInfo))
                {
                    if (hitInfo.transform.GetComponentInChildren<*YOUR_CUBE_CONTROL_CLASS_NAME*>() == this)
                    {
                        touched[i] = true;
                    }
                }
            }
            else if (touched[i] && Input.GetTouch(i).phase == TouchPhase.Moved)
            {
                // Get movement of the finger since last frame
                Vector3 touchDeltaPosition = Input.GetTouch(i).deltaPosition;

                // Move object across XY plane
                transform.Translate(touchDeltaPosition.x * speed, 0, 0);

                Vector3 boundaryVector = transform.position;   
                boundaryVector.x = Mathf.Clamp (boundaryVector.x, -5.5f, -2.8f);
                transform.position = boundaryVector;
            }
        }
        else
        {
            touched  = false;
        }
    }
}

希望对您有所帮助，
