沿着Y轴移动玩家

本文关键字：玩家 移动 沿着 | 更新日期: 2023-09-27 18:10:09

我最近已经从SpriteKit和Swift转向Unity，并且我已经开始了一个Android项目。我想要的是只沿着Y方向上下移动玩家。在xcode中，我只需这样做:

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
    for touch: AnyObject in touches {
        let location = touch.locationInNode(self)
        let action = SKAction.moveToY(location.y, duration: 0.7)
        action.timingMode = .EaseInEaseOut
        player.runAction(action)
    }
}

这种类型的代码会以同样的方式转换为c#吗?或者它的工作方式不同。

** UPDATE **

这是我用下面的答案之一尝试的代码，但玩家正在消失而不是移动，有什么建议吗?我所追求的是让玩家移动到点击屏幕的地方，但只能在Y轴上。谢谢:)

 Vector2 touchPosition;
        [SerializeField] float speed = 1f;   
void Update() {
            for (var i = 0; i < Input.touchCount; i++) {
                if (Input.GetTouch(i).phase == TouchPhase.Began) {
                    // assign new position to where finger was pressed
                    transform.position = new Vector3 (transform.position.x, Input.GetTouch(i).position.y, transform.position.z);
                }
            }    
        }

沿着Y轴移动玩家

你可以通过调用transform.Translate()来移动场景中的任何对象，或者通过引用另一个对象的transform并调用Translate()。

基于手指移动移动当前脚本的场景对象 

Vector2 touchDeltaPosition;
[SerializeField] float speed = 1f;
void Update() {
    for (var i = 0; i < Input.touchCount; i++) {
        if (Input.GetTouch(i).phase == TouchPhase.Moved) {
            // get new finger position
            touchDeltaPosition = Input.GetTouch(i).deltaPosition;
            // move scene object along y axis
            transform.Translate(0f, -touchDeltaPosition.y * speed, 0f);
        }
    }    
}

移动当前脚本的场景对象到手指按压位置

void Update() {
    for (var i = 0; i < Input.touchCount; i++) {
        if (Input.GetTouch(i).phase == TouchPhase.Began) {
            // assign new position to where finger was pressed
            transform.position = new Vector3 (transform.position.x, Input.GetTouch(i).position.y, transform.position.z);
        }
    }    
}

public float speed = 5.0f;
public void Update()
{
    Vector3 moveDelta = new Vector3(0f, Input.GetAxis("Vertical"), 0f);
    transform.Translate(moveDelta * speed * Time.deltatime)
}

对于那些需要知道的人来说，这是我的工作方式:

public GameObject;

public float smooth = 2;
private Vector3 _endPosition;
private Vector3 _startPosition;
private void Awake()
{
    _startPosition = thingToMove.transform.position;
}
private void Update()
{
    if(Application.platform == RuntimePlatform.Android || Application.platform == RuntimePlatform.IPhonePlayer)
    {
        _endPosition = HandleTouchInput();
    }
    else
    {
        _endPosition = HandleMouseInput();
    }
    thingToMove.transform.position = Vector3.Lerp(thingToMove.transform.position, new Vector3(transform.position.x, _endPosition.y, 0), Time.deltaTime * smooth);
}
private Vector3 HandleTouchInput()
{
    for (var i = 0; i < Input.touchCount; i++) 
    {
        if (Input.GetTouch(i).phase == TouchPhase.Began) 
        {
            var screenPosition = Input.GetTouch(i).position;
            _startPosition = Camera.main.ScreenToWorldPoint(screenPosition);
        }
    }
    return _startPosition;
}
private Vector3 HandleMouseInput()
{
    if(Input.GetMouseButtonDown(0))
    {
        var screenPosition = Input.mousePosition;
        _startPosition = Camera.main.ScreenToWorldPoint(screenPosition);
    }
    return _startPosition;
}
