c# - Unity3d Swipe 跳转不是很灵敏

Question

我正在尝试使用 unity3D 构建安卓游戏。这是我编写的角色 Controller 脚本。向上滑动部分接近我评论过的代码的末尾。

float speed = 11.0f;
public float jumpForce = 0.005f;


public float FingerInitialPosition = 0f;
public float FingerMovedPosition = 0f;
public float startTouchPosition = 0f;
public float endTouchPosition = 0f;

public Rigidbody2D rb;
public Vector3 jump;
public int jumpCount;


Vector3 moveDir = Vector3.zero;

// Start is called before the first frame update
void Start()
{
    rb = GetComponent<Rigidbody2D>();
    jump = new Vector3(0.0f, 1f, 0.0f);

}


void OnCollisionEnter2D(Collision2D col)
{

    Debug.Log("Collided");
    jumpCount=0;            

}

void FixedUpdate()
{

    Debug.Log(jumpCount);
    if(transform.position.y < -14) { SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex); }


    foreach (Touch FingerTouch in Input.touches)
    {
        if (FingerTouch.position.x < Screen.width / 2)
        {
            if (FingerTouch.phase == TouchPhase.Began)
            {
                FingerInitialPosition = FingerTouch.position.x;
            }
            else if (FingerTouch.phase == TouchPhase.Moved)
            {
                FingerMovedPosition = FingerTouch.position.x;

                if (FingerMovedPosition > FingerInitialPosition)
                {
                     float hval = rb.velocity.x;
                     hval += 19f;
                     hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                     rb.velocity = new Vector2(hval, rb.velocity.y);



                }
                else if (FingerMovedPosition < FingerInitialPosition)
                {
                    float hval = rb.velocity.x;
                    hval -= 19f;
                    hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                    rb.velocity = new Vector2(hval, rb.velocity.y);
                }
            }
            else if (FingerTouch.phase == TouchPhase.Ended)
            {
                FingerInitialPosition = 0f;
                FingerMovedPosition = 0f;

            }
            else //NEW PART!//
            {
                FingerMovedPosition = FingerTouch.position.x;
                if (FingerMovedPosition > FingerInitialPosition)
                {
                    float hval = rb.velocity.x;
                    hval += 19f;
                    hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                    rb.velocity = new Vector2(hval, rb.velocity.y);
                }
                else if (FingerMovedPosition < FingerInitialPosition)
                {
                    float hval = rb.velocity.x;
                    hval -= 19f;
                    hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                    rb.velocity = new Vector2(hval, rb.velocity.y);

                }
            }
        }

        // The part I think needs fixing
        // The swipe Up part where I make the player jump

        if (FingerTouch.position.x > Screen.width / 2)
        {
            for (int i = 0; i < Input.touchCount; i++)
            {
                Touch touch = Input.GetTouch(i);
                if (touch.phase == TouchPhase.Began)
                {
                    startTouchPosition = touch.position.y;
                }
                else if (touch.phase == TouchPhase.Ended)
                {
                    endTouchPosition = touch.position.y;
                    if (endTouchPosition > startTouchPosition)
                    {
                        if (jumpCount<1) {
                            rb.AddForce(jump * jumpForce, ForceMode2D.Impulse);
                            jumpCount += 1;
                        }

                    }
                }
            }
        }



    }



}

在屏幕左侧滑动(水平)允许玩家左右移动，在屏幕右侧向上滑动允许玩家跳跃我的问题是跳跃不是很灵敏，我有做了一个测试它只响应了 3/5 次。

我还附上了我的播放器的截图

不要使用嵌套循环，而是继续使用 FingerTouch元素。

另外，不要在手指移开时进行比较，这可能会导致延迟，只要通过检查 FingerTouch.deltaPosition.y 看到它向上移动时就激活它。 :

void FixedUpdate()
{

    Debug.Log(jumpCount);
    if(transform.position.y < -14) { SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex); }


    foreach (Touch FingerTouch in Input.touches)
    {
        if (FingerTouch.position.x < Screen.width / 2)
        {
            if (FingerTouch.phase == TouchPhase.Began)
            {
                FingerInitialPosition = FingerTouch.position.x;
            }
            else if (FingerTouch.phase == TouchPhase.Moved)
            {
                FingerMovedPosition = FingerTouch.position.x;

                if (FingerMovedPosition > FingerInitialPosition)
                {
                     float hval = rb.velocity.x;
                     hval += 19f;
                     hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                     rb.velocity = new Vector2(hval, rb.velocity.y);



                }
                else if (FingerMovedPosition < FingerInitialPosition)
                {
                    float hval = rb.velocity.x;
                    hval -= 19f;
                    hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                    rb.velocity = new Vector2(hval, rb.velocity.y);
                }
            }
            else if (FingerTouch.phase == TouchPhase.Ended)
            {
                FingerInitialPosition = 0f;
                FingerMovedPosition = 0f;

            }
            else //NEW PART!//
            {
                FingerMovedPosition = FingerTouch.position.x;
                if (FingerMovedPosition > FingerInitialPosition)
                {
                    float hval = rb.velocity.x;
                    hval += 19f;
                    hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                    rb.velocity = new Vector2(hval, rb.velocity.y);
                }
                else if (FingerMovedPosition < FingerInitialPosition)
                {
                    float hval = rb.velocity.x;
                    hval -= 19f;
                    hval *= Mathf.Pow(0.5f, Time.deltaTime * 10f);
                    rb.velocity = new Vector2(hval, rb.velocity.y);

                }
            }
        }

        else if (FingerTouch.position.x > Screen.width / 2)
        {
            if (FingerTouch.deltaPosition.y > 0) {
                if (jumpCount<1) {
                    rb.AddForce(jump * jumpForce, ForceMode2D.Impulse);
                    jumpCount += 1;
                }
            }
        }

    }
}

这可能只是部分解决方案。如果这仍然不起作用，我很好奇是否删除了 if (jumpCount<1)检查使它工作。如果是这样，问题似乎与您如何将其设置回 0 有关。 .
