Question

我有两难选择。我正在尝试执行以下操作：我有3个按钮，单击一个按钮，它增加，单击另一个按钮，它增加，上一个按钮恢复到原始大小。

    private void PigeonholesHasClicked(GameObject target, MouseEventType type)
{
    if (type == MouseEventType.CLICK)
    {
        TargetIndex = System.Array.IndexOf(Pigeonholes, target);
        PigeonholesTrasnform();
    }
}

Vector3 mPosition;
int lastIndex = 0;
public float mIndex;
private void PigeonholesTrasnform()
{
    mPosition = new Vector3(Pigeonholes[TargetIndex].transform.position.x - mIndex, Pigeonholes[TargetIndex].transform.position.y, 0f);
    Pigeonholes[TargetIndex].transform.DOMove(mPosition, 0.5f);
    Pigeonholes[TargetIndex].GetComponent<BoxCollider2D>().enabled = false;
    if (TargetIndex != lastIndex)
    {
        mPosition = new Vector3(Pigeonholes[lastIndex].transform.position.x + mIndex, Pigeonholes[lastIndex].transform.position.y, 0f);
        Pigeonholes[lastIndex].transform.DOMove(mPosition, 0.5f);
        for (int i = 0; i < Pigeonholes.Length; i++)
        {
            if (i != TargetIndex)
                Pigeonholes[i].GetComponent<BoxCollider2D>().enabled = true;
        }
    }
    lastIndex = TargetIndex;
}

问题是，如果我单击1或2按钮，则0按钮向右移动0.4;如果我首先开始输入0，然后按1或2，那么一切正常。 lastIndex最初为0，如果我将其设为-1，则会给我一个错误。帮助！！！

开始时，您尚未选择任何东西=>实际上，您实际上不希望最初是0。

我起初会离开lastIndex = -1;，而只是忽略这些行

mPosition = new Vector3(Pigeonholes[lastIndex].transform.position.x + mIndex, Pigeonholes[lastIndex].transform.position.y, 0f);
Pigeonholes[lastIndex].transform.DOMove(mPosition, 0.5f);

如果它仍然是-1->表示之前未选择任何内容：

if(lastIndex >= 0)
{
    mPosition = new Vector3(Pigeonholes[lastIndex].transform.position.x + mIndex, Pigeonholes[lastIndex].transform.position.y, 0f);
    Pigeonholes[lastIndex].transform.DOMove(mPosition, 0.5f);
}
