Unity C# 在 android 上点击和滑动

Question

我目前正在编写一个与障碍物统一的简单游戏，这是一个无休止的游戏，玩家可以跳跃、左右移动来避开这些障碍物。该游戏适用于华硕和华为设备，但不适用于三星。使用三星设备时，当我点击屏幕时播放器不会跳跃，但滑动有效。

我的代码：

void change()

{

    if (Input.touchCount > 0)

    {

        Touch touch = Input.touches[0];

        switch (touch.phase)

        {

            case TouchPhase.Began:

                startPos = touch.position;

                break;

            case TouchPhase.Ended:

                float swipeDistHorizontal = (new Vector3(touch.position.x, 0, 0) - new Vector3(startPos.x, 0, 0)).magnitude;

                if (swipeDistHorizontal > minSwipeDistX)

                {

                    float swipeValue = Mathf.Sign(touch.position.x - startPos.x);

                    if (swipeValue > 0)

                        {//right swipe

                        anim.Play(change_Line_Animation);

                        transform.localPosition = second_PosOfPlayer;

                        SoundManager.instance.PlayMoveLineSound();

                    }

                    else if (swipeValue < 0)

                    {//left swipe

                        anim.Play(change_Line_Animation);

                        transform.localPosition = first_PosOfPlayer;

                        SoundManager.instance.PlayMoveLineSound();

                    }

                }

                else {

                      if (!player_Jumped){

                          anim.Play(jump_Animation);

                          player_Jumped = true;

                          SoundManager.instance.PlayJumpSound();

                      }

                }

                break;

        }

    }

}

此函数在 update() 函数中调用。

由于我是新来的，我还不能使用评论来提出更多问题。使用三星时到底什么不起作用？不过，您可以简化计算。&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; float swipeValue = touch.position.x - startPos.x; //Mathf.Sign(touch.position.x - startPos.x);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (swipeValue > 0)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {//right swipe&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; anim.Play(change_Line_Animation);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; transform.localPosition = second_PosOfPlayer;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; SoundManager.instance.PlayMoveLineSound();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else if (swipeValue < 0)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {//left swipe&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; anim.Play(change_Line_Animation);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; transform.localPosition = first_PosOfPlayer;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; SoundManager.instance.PlayMoveLineSound();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }仅比较 > 或 < 小于 0 时不需要 Math.Sign。&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; case TouchPhase.Began:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; startPos = touch.position.x; // startPos could be float&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; break;因此，float swipeDistHorizontal = Mathf.Abs(touch.position.x - startPos);如果游戏仅使用水平滑动，则不需要向量来存储和计算滑动增量。如果您提供更多信息，我很乐意提供更多帮助。
