我目前在国际象棋游戏中面临着悬停的pb

Question

首先，我创建了过度效果并确保它有效，但是当我添加 Input.getmousebutton 时，它会干扰悬停，并且以前无论我将鼠标移到板上，悬停的方块都会更改其颜色，但现在它不再显示

    RaycastHit info;
    Ray ray = currentCamera.ScreenPointToRay(Input.mousePosition);

    if (Physics.Raycast(ray, out info, 150, LayerMask.GetMask("Square","Hover","Highlight")))
    {
        //Get the indexes of the Square you hit
        Vector2Int hitPosition = LookUpSquareIndex(info.transform.gameObject);

        // From not hovering to hovering
        if (currentHover == -Vector2Int.one)
        {
            currentHover = hitPosition;
            Squares[hitPosition.x, hitPosition.y].layer = LayerMask.NameToLayer("Hover");
        }

        // From hovering one square to hovering another square
        if (currentHover != hitPosition)
        {
            Squares[currentHover.x, currentHover.y].layer = containsValidMove(ref availableMoves, currentHover) ? LayerMask.NameToLayer("Highlight") : LayerMask.NameToLayer("Square");
            currentHover = hitPosition;
            Squares[hitPosition.x, hitPosition.y].layer = LayerMask.NameToLayer("Hover");
        }
        //pressing the mouse button
        if (Input.GetMouseButtonDown(0))
        {
            if (chessPieces[hitPosition.x, hitPosition.y] != null)
            {

                //Is it Our Turn
                if ((chessPieces[hitPosition.x, hitPosition.y].team==0 && isWhiteTurn) || (chessPieces[hitPosition.x, hitPosition.y].team == 1 && !isWhiteTurn))
                {

                    currentlyDragging = chessPieces[hitPosition.x, hitPosition.y];
                    //getting a list of available Moves , heighlight the available moves
                    availableMoves = currentlyDragging.GetAvailableMoves(ref chessPieces, SQUARE_COUNT_X, SQUARE_COUNT_Y);
                    //Getting a Special Moves List 
                    specialMove = currentlyDragging.GetSpecialMoves(ref chessPieces, ref moveList, ref availableMoves);
                    highlightSquares();
                }
            }

        }
        // Releasing the mouse Button
        if (currentlyDragging != null && Input.GetMouseButtonUp(0))
        {
            Vector2Int previousPosition = new Vector2Int(currentlyDragging.currentX, currentlyDragging.currentY);

            bool validMove = MoveTo(currentlyDragging, hitPosition.x, hitPosition.y);
            if (!validMove)
                currentlyDragging.setPosition(GetSquaresCenter(previousPosition.x, previousPosition.y));

            currentlyDragging = null;
            removehighlightSquares();

        }

        else
        { 
            if (currentHover != -Vector2Int.one)
            {
                Squares[currentHover.x, currentHover.y].layer = (containsValidMove(ref availableMoves, currentHover)) ? LayerMask.NameToLayer("Highlight") : LayerMask.NameToLayer("Square");
                currentHover = -Vector2Int.one;

                if (currentlyDragging && Input.GetMouseButtonUp(0))
                {
                    currentlyDragging.setPosition(GetSquaresCenter(currentlyDragging.currentX, currentlyDragging.currentY));
                    currentlyDragging = null;
                    removehighlightSquares(); 
                }
            }
        }

        // while dragging a piece
        if (currentlyDragging)
        {
            Plane horizontalePlane = new Plane(Vector3.up , Vector3.up*Yoffset/1000);
            float distance = 0.0f;
            if(horizontalePlane.Raycast(ray, out distance))
                currentlyDragging.setPosition(ray.GetPoint(distance)+Vector3.up*dragOffset);
        }

    }

我尝试添加多个功能，例如handleHoerEffect和HandleMouseButtonUp和Down

Answer 1

我认为问题可能出在此处的

else

。

    // Releasing the mouse Button
    if (currentlyDragging != null && Input.GetMouseButtonUp(0))
    {
        //your code
    }
    else
    { 
        if (currentHover != -Vector2Int.one)
        {
            Squares[currentHover.x, currentHover.y].layer = (containsValidMove(ref availableMoves, currentHover)) ? LayerMask.NameToLayer("Highlight") : LayerMask.NameToLayer("Square");
            currentHover = -Vector2Int.one;

            //your code
        }
    }

我猜测这段代码是在 Update() 循环或类似的循环中运行的。第 1 帧以下条件将为真，并且 currentHover 将被分配一个值：

    if (currentHover == -Vector2Int.one)
    {
        currentHover = hitPosition;
        Squares[hitPosition.x, hitPosition.y].layer = LayerMask.NameToLayer("Hover");
    }

下一帧，如果您没有释放鼠标按钮，则此条件将为 false：

(currentlyDragging != null && Input.GetMouseButtonUp(0))

会将代码路由到上面提到的 else 语句，并且

if (currentHover != -Vector2Int.one)

将为 true，因为它在前一帧中被分配了值

这最终将导致图层被分配给

LayerMask.NameToLayer("Square")

并且当前的悬停被设置为默认值，如果我的上述假设是正确的，这个循环将继续

                Squares[currentHover.x, currentHover.y].layer = (containsValidMove(ref availableMoves, currentHover)) ? LayerMask.NameToLayer("Highlight") : LayerMask.NameToLayer("Square");
            currentHover = -Vector2Int.one;

我无法在本地进行完全测试，因为所提供的代码片段仅显示了一小部分上下文，因此我最初的假设可能完全错误，但我希望这无论如何都会有所帮助
