玩家希望从一次触摸(统一)向左和右移动

Question

我在联合太空射击队做了这个游戏。在我的空间射击有2个按钮，它工作的左和右移动。我想当我们点击左边按钮的时候，玩家只能在单一的触摸中向左走，就像右键一样。

这是我在游戏中使用的一些密码。请帮我摆脱这一切。

Answer 1

在Player Controller脚本中创建：

public Vector3 playerDirection = Vector3.zero;

然后用触控代替：

if (moveLeft.HitTest(Input.GetTouch(i).position, Camera.main))
{
    if (Input.touchCount > 0)
    {
        playerMove.MoveLeft();
    }
}
if (moveRight.HitTest(Input.GetTouch(i).position, Camera.main))
{
    if (Input.touchCount > 0)
    {
        playerMove.MoveRight();
    }
}

使用：

if (moveLeft.HitTest(Input.GetTouch(i).position, Camera.main))
{
    if (Input.touchCount > 0)
    {
        playerMove.playerDirection = Vector3.left;
    }
}
if (moveRight.HitTest(Input.GetTouch(i).position, Camera.main))
{
    if (Input.touchCount > 0)
    {
        playerMove.playerDirection = Vector3.right;
    }
}

然后在Player Controller的更新方法中使用：

transform.Translate(playerDirection * speedMove * Time.deltaTime);

Answer 2

public class PlayerController {
    public EPlayerState playerState = EPLayerState.Idle;

    void Update () {
      // If click right button
      playerState = EPlayerState.MoveRight;
      // Else if click left button
      playerState = EPlayerState.MoveLeft

      if (playerState == EPlayerState.MoveRight)
          // Move player right;
      if (playerState == EPlayerState.MoveLeft
          // Move player right;
    }
}

public enum EPlayerState {
    Idle,
    MoveRight,
    MoveLeft
}

您还可以使用名为isRight的布尔值，当它是真时向右移动，当它是假时向左移动。然后，单击“左”或“右”按钮，只需更改变量。

`使用UnityEngine；公共类HalfScreenTouchMovement : MonoBehaviour {私有浮点数screenCenterX；

private void Start()
{
    // save the horizontal center of the screen
    screenCenterX = Screen.width * 0.5f;
}

private void Update()
{
    // if there are any touches currently
    if(Input.touchCount > 0)
    {
        // get the first one
        Touch firstTouch = Input.GetTouch(0);

        // if it began this frame
        if(firstTouch.phase == TouchPhase.Began)
        {
            if(firstTouch.position.x > screenCenterX)
            {
                // if the touch position is to the right of center
                // move right
            }
            else if(firstTouch.position.x < screenCenterX)
            {
                // if the touch position is to the left of center
                // move left
            }
        }
    }
}
