检测颜色是否匹配

Question

我正在尝试检测Unity2D中的颜色是否匹配（2x2），但它并不完全有效。我有16个瓷砖，有4种不同的颜色。 我正在检测颜色是否与脚本相匹配，脚本附着在每个碰撞器上，该碰撞器与周围的4个瓦片碰撞。在每个colider前面是一个按钮，它将围绕该按钮（对撞机）的4个瓷砖旋转到右边。对撞机的脚本有一个名为childTiles的列表。该列表包含该对撞机周围的4个瓦片，用于检测一个列表中是否有4个相同颜色的瓦片。看起来像这样。 （GIF）https://gyazo.com/a2a5c8a5051e937338807fb5ecfaa4ec

此脚本附加到每个对撞机。总共有9个碰撞器（每个碰撞器都在一个按钮后面）。

void OnTriggerEnter2D(Collider2D col)
{
    if (col.gameObject.tag == "Tile") 
    {
        ChildTiles.Add (col.gameObject);

正如您在GIF中看到的那样，存在一个问题。问题是当有4种颜色匹配时，它不会返回True。如果你点击一个周围有4个相同颜色的图块的按钮，它只返回True。只有这样才返回True。因此，您匹配4种颜色，它不会返回True，您单击其周围有4种颜色的按钮，它将返回True。如果匹配4种颜色，如何使其立即返回True？如您所见，我只使用左上角，右上角，左下角和右下角对撞机，因为这些是唯一可能同时具有4个相同颜色的瓷砖的碰撞器。
