Question

我正在尝试将项目从Web转换为Android。我使用带箭头键的相机，我试图触摸屏幕并向上和向下左右。

这是我在Web上的代码：

if (Input.GetKey(KeyCode.UpArrow) && Camera.main.transform.position.y < CameraYLimitUp)//Up Camera Mvt
        { transform.Translate(-Vector3.up * Time.deltaTime * 20); }

       if (Input.GetKey(KeyCode.DownArrow) && Camera.main.transform.position.y > CameraYLimitDown)//Down Camera Mvt
        { transform.Translate(Vector3.up * Time.deltaTime * 20); }

        if (Input.GetKey(KeyCode.LeftArrow) && Camera.main.transform.position.x > CameraXLimitLeft)//Left Camera Mvt
        { transform.Translate(Vector3.right * Time.deltaTime * 20); }

        if (Input.GetKey(KeyCode.RightArrow) && Camera.main.transform.position.x < CameraXLimitRight)//Right Camera Mvt
        { transform.Translate(Vector3.left * Time.deltaTime * 20); }

感谢您的帮助

您无法在Android中使用箭头键，而是需要模拟像模拟棒这样的东西。此脚本模拟Android中的简单模拟棒：

public Vector2 startPos;
public Vector2 endPos;
public bool fingerHold = false;

void Update () {
    if(Input.touchCount > 0){                      // get total touches on screen
        Touch touch = Input.GetTouch(0);
        if(touch.phase == TouchPhase.Began){       // when finger starts touching
            startPos = touch.position;             // get its position
            fingerHold = true;
        }
        else if(touch.phase == TouchPhase.Moved){  // when finger moves
            endPos = touch.position;               // get its position too
        }
        else if(touch.phase == TouchPhase.Ended){  // when finger released
            fingerHold = false;                    
        }
    }
    if(fingerHold){

        float deltaX = endPos.x - startPos.x;      // get the difference of x position
        float deltaY = endPos.y - startPos.y;      // and the y position
        bool horizontal = false;

        if(Mathf.Abs (deltaX) > Mathf.Abs (deltaY)) // if difference of x is bigger than y
            horizontal = true;                      // meaning we want it to move horizontally

        if(horizontal){
            if(deltaX > 0) // if difference of x is bigger than 0, meaning finger is moving right, translate it to right
                transform.Translate(Vector3.right * Time.deltaTime);
            else if(deltaX < 0) // the reverse, move left
                transform.Translate(Vector3.left * Time.deltaTime);
        }
        else{ // and so on
            if(deltaY > 0)
                transform.Translate(Vector3.up * Time.deltaTime);
            else if(deltaY < 0)
                transform.Translate(Vector3.down * Time.deltaTime);
        }
    }
}

您可以将此脚本与您的脚本合并，因为网络没有触摸，因此此脚本不会与箭头脚本冲突。

我的工作代码：

public float CameraYLimitUp;
public float CameraYLimitDown;
public float CameraXLimitLeft;
public float CameraXLimitRight;
public Vector2 startPos;
public Vector2 endPos;
public bool fingerHold = false;

// Use this for initialization
void Start () {
    CameraYLimitUp = -1f;
    CameraYLimitDown = 1f;
    CameraXLimitLeft = 1f;
    CameraXLimitRight = -1f;
}

// Update is called once per frame
void Update () {
    if (Input.GetKey(KeyCode.UpArrow) && transform.position.y > CameraYLimitUp)
    { transform.Translate(Vector3.down * Time.deltaTime * 20); }

    if (Input.GetKey(KeyCode.DownArrow) && transform.position.y < CameraYLimitDown)
    { transform.Translate(Vector3.up * Time.deltaTime * 20); }

    if (Input.GetKey(KeyCode.LeftArrow) && transform.position.x < CameraXLimitLeft)
    { transform.Translate(Vector3.right * Time.deltaTime * 20); }

    if (Input.GetKey(KeyCode.RightArrow) && transform.position.x > CameraXLimitRight)
    { transform.Translate(Vector3.left * Time.deltaTime * 20); }

    if(Input.touchCount > 0){                      
        Touch touch = Input.GetTouch(0);
        if(touch.phase == TouchPhase.Began){       
            startPos = touch.position;             
            fingerHold = true;
        }
        else if(touch.phase == TouchPhase.Moved){  
            endPos = touch.position;               
        }
        else if(touch.phase == TouchPhase.Ended){  
            fingerHold = false;                    
        }
    }

    if(fingerHold){

        float deltaX = endPos.x - startPos.x;      
        float deltaY = endPos.y - startPos.y;      
        bool horizontal = false;

        if(Mathf.Abs (deltaX) > Mathf.Abs (deltaY)) 
            horizontal = true;                      

        if(horizontal){
            if(deltaX < 0 && transform.position.x < CameraXLimitLeft)
                transform.Translate(Vector3.right * Time.deltaTime * 10);
            else if(deltaX > 0 && transform.position.x > CameraXLimitRight)
                transform.Translate(Vector3.left * Time.deltaTime * 10);
        }
        else{ 
            if(deltaY < 0 && transform.position.y < CameraYLimitDown)
                transform.Translate(Vector3.up * Time.deltaTime * 10);
            else if(deltaY > 0 && transform.position.y > CameraYLimitUp)
                transform.Translate(Vector3.down * Time.deltaTime * 10);
        }
    }
}

您需要查看移动控件，只需导入Standart Assests（Mobile）*包并查看第一和第三人称控制器预制件，当然还可以查看包中的角色控制器脚本。从那里开始，这一切都非常简单。
