试图做一个窗台。问题：transform.position 总是 returns 到 vector( 0, 0)

Question

我正在尝试制作一种让玩家攀登壁架的方法。我有两个光线投射，一个用于 Ledge，一个用于 Wall 检测。我的壁架是假的，然后爬上壁架。问题来了：当 Wall check 为真并且 ledge Check 为真时，将 player transform.position 设置为靠近 ledge。然后 transform.position 到壁架上方。但出于某种原因，每当我尝试在壁架附近调用 Set player transform.position 时，它只会传送回默认矢量值 0、0.

    [Header("Ledge check")]
    private bool canClimbLedge = false;
    private bool ledgeDetected;

    private Vector2 workspace;

    //NEW SHIT
    private Vector2 detectedPos;
    private Vector2 cornerPos;
    private Vector2 startPos;
    private Vector2 stopPos;
    [Header("Ledge Climb State")]
    public Vector2 startOffset;
    public Vector2 stopOffset;

private void FixedUpdate()
{        if (coll.isTouchingWall && !coll.isTouchingRightLedge || !coll.isTouchingLeftLedge)
        {
            SetDetectedPosition(transform.position);
        }
}

void Update()
    {
        DetermineCornerPosition();

        if (coll.onWall && !coll.isTouchingRightLedge)
        CheckLedgeClimb();
        if(canClimbLedge && coll.onGround)
        FinishLedgeClimb();

        if (dir.x < 0)
        {
            if (groundTouch == true && !wallGrab)
               // dustParticle.Play();

            if (wallGrab != true)
            {
                side = -1;
                //anim.Flip(side);

            }

        }

        if (dir.x > 0)
        {
            if (groundTouch == true && !wallGrab)
                // dustParticle.Play();

                if (wallGrab != true)
                {
                    side = 1;
                    // anim.Flip(side);
                }
        }
    }

public void SetDetectedPosition(Vector2 pos) => detectedPos = pos;
    public Vector2 DetermineCornerPosition()
    {
        RaycastHit2D xHit = Physics2D.Raycast(coll.wallCheck.position, Vector2.right * side, coll.wallCheckDistance, coll.groundLayer);
        float xDist = xHit.distance;
        workspace.Set((xDist * side) * side, 0.015f);
        RaycastHit2D yHit = Physics2D.Raycast(coll.ledgeCheck.position + (Vector3)(workspace), Vector2.down, coll.ledgeCheck.position.y - coll.wallCheck.position.y + 0.015f, coll.groundLayer);
        float yDist = yHit.distance;

        //Upper Corner Position of ledge
        workspace.Set(coll.wallCheck.position.x + (xDist * side), coll.ledgeCheck.position.y - yDist);
        return workspace;
    }
    private void CheckLedgeClimb()
    {

        if (coll.isTouchingWall && !coll.isTouchingRightLedge && !ledgeDetected)
        {
            ledgeDetected = true;
            //Freeze player in the detectedPos
            rb.velocity = Vector2.zero;
            rb.gravityScale = 0f;
            transform.position = detectedPos;
            cornerPos = DetermineCornerPosition();
        }

        if(ledgeDetected && !canClimbLedge)
        {
            canClimbLedge = true;
            startPos.Set(cornerPos.x - (side * startOffset.x), cornerPos.y - startOffset.y);
            stopPos.Set(cornerPos.x + (side * stopOffset.x), cornerPos.y + stopOffset.y);
        }

        Debug.Log(startPos);
        canMove = false;
        transform.position = startPos;
        canClimbLedge = true;
    }

    public void FinishLedgeClimb()
    {
     //Call the last part of climbing the ledge
    }

在碰撞脚本中：

void FixedUpdate()
{
    isTouchingWall = Physics2D.Raycast(wallCheck.position, transform.right, wallCheckDistance, groundLayer);

    isTouchingRightLedge = isTouchingWall = Physics2D.Raycast(ledgeCheck.position, transform.right, wallCheckDistance, groundLayer);
}

非常感谢任何帮助，如果您有任何其他制作壁架攀爬器的解决方案，我会洗耳恭听。

Answer 1

我重新评估了目的是为了脚本。问题是 Raycast 并没有真正正常工作如果玩家面向左侧，我不是让光线投射在一个方向上，而是让它跟随变化 180 度。

并且在我的游戏中，我不希望玩家能够挂在窗台上，所以 transform.position 被移除了。变化：

碰撞脚本：

 isTouchingWall = Physics2D.Raycast(wallCheck.position, transform.right * move.side, wallCheckDistance, groundLayer);

        isTouchingLedge = Physics2D.Raycast(ledgeCheck.position, transform.right * move.side, wallCheckDistance, groundLayer);

ClimbLedge 函数：

 private void CheckLedgeClimb()
    {

        if (coll.isTouchingWall && !coll.isTouchingLedge && !ledgeDetected)
        {
            //Reference point to startPos and stopPos
            ledgeDetected = true;
            //Freeze player in the detectedPos
            rb.velocity = Vector2.zero;
            rb.gravityScale = 0f;
            transform.position = detectedPos;
            cornerPos = DetermineCornerPosition();
            Debug.Log("cornerPos Vector Value: " + cornerPos);
            canClimbLedge = false;
        }

        if(ledgeDetected && !canClimbLedge)
        {

            //This part is only necessary if you want the player to hang from a ledge.
            /*startPos.Set(cornerPos.x - (side * startOffset.x), cornerPos.y - startOffset.y);
            stopPos.Set(cornerPos.x + (side * stopOffset.x), cornerPos.y + stopOffset.y);

            Debug.Log("startPos when ledgeDetected + !canClimbLedge:" + startPos);
            canMove = false;
            transform.position = startPos;
            rb.velocity = Vector2.zero;
            rb.gravityScale = 0f;*/

            stopPos.Set(cornerPos.x + (side * stopOffset.x), cornerPos.y + stopOffset.y);
            rb.velocity = Vector2.zero;
            rb.gravityScale = 0f;
            canMove = false;
            canClimbLedge = true;
        }
    }

    public void FinishLedgeClimb()
    {
       if (canClimbLedge)
        {
            transform.position = stopPos;
            canClimbLedge = false;
            canMove = true;
            ledgeDetected = false;
            Debug.Log("transform.position = stopPos");

            //anim.SetBool("canClimbLedge", canClimbLedge);
        } 
    }

这是可行的，但玩家 transform.position 到 stopPos 的时间有时会延迟。
