Question

我试图考虑一个通用方法，该方法将对当前代码有所帮助。这不是问题，我只是想知道是否可以这样做。我有两种基本上可以完成相同操作的方法，但是它们使用不同的转换。我正在考虑如何实现通用方法来编写此代码。

private void ImagePieceClickEvent(GameObject target, MouseEventType type)
{
    if (type == MouseEventType.CLICK && canClick)
    {
//imagePiceTarget has Transform type
        if (imagePieceTarget != null && imagePieceTarget != target.transform)
            imagePieceTarget.GetComponent<SpriteRenderer>().DOFade(0.7f, 0.2f);
        if (imagePieceTarget == target.transform)
        {
            imagePieceTarget.GetComponent<SpriteRenderer>().DOFade(0.7f, 0.2f);
            imagePieceTarget = null;
        }
        else
        {
            imagePieceTarget = target.transform;
            imagePieceTarget.GetComponent<SpriteRenderer>().DOFade(1f, 0.2f).OnComplete(CheckAnswer);
        }
    }
}

private void ClonePieceClickEvent(GameObject target, MouseEventType type)
{
    if (type == MouseEventType.CLICK && canClick)
    {
//clonePieceTarget has Transform type
        if (clonePieceTarget != null && clonePieceTarget != target.transform)
            clonePieceTarget.transform.DOScale(0.7f, 0.2f);
        if (clonePieceTarget == target.transform)
        {
            clonePieceTarget.transform.DOScale(0.7f, 0.2f);
            clonePieceTarget = null;
        }
        else
        {
            clonePieceTarget = target.transform;
            clonePieceTarget.transform.DOScale(1f, 0.2f).OnComplete(CheckAnswer);
        }
    }
}

所有处于IF条件的代码都将以通用方法实现，然后调用它。为什么我不能这样做，因为第一种方法调用.DOFade（）方法，而第二种方法调用DOScale（）。我想知道是否可以使用通用方法进行简化，谢谢。

我会使用System.Action和ref keyword来解决您的问题。

尝试以下操作：

private void PieceClickEvent(Transform target, MouseEventType type, ref Transform pieceTarget, System.Action<Transform> onFocus, System.Action<Transform> onBlur )
{
    if (type == MouseEventType.CLICK && canClick)
    {
        if (pieceTarget != null && pieceTarget != target && onBlur != null)
        {
            onBlur( pieceTarget ) ;
        }

        if (imagePieceTarget == target.transform)
        {
            if( onBlur != null )
                onBlur( pieceTarget ) ;

            pieceTarget = null;
        }
        else
        {
            pieceTarget = target;
            if( onFocus != null )
                onFocus( pieceTarget ) ;
        }
    }
}

// ...

PieceClickEvent(
    target.transform,
    type,
    ref imagePieceTarget,
    t => t.GetComponent<SpriteRenderer>().DOFade(1f, 0.2f).OnComplete(CheckAnswer),
    t => t.GetComponent<SpriteRenderer>().DOFade(0.7f, 0.2f)
);

PieceClickEvent(
    target.transform,
    type,
    ref clonePieceTarget,
    t => t.DOScale(1f, 0.2f).OnComplete(CheckAnswer),
    t => t.DOScale(0.7f, 0.2f)
);

从两个简单的方法中实现通用方法
