        flipCard ();

    }

    void flipCard() {

        if(state == 0 && !DO_NOT)
            GetComponent<Image> ().sprite = cardBack;
        else if (state == 1 && !DO_NOT)
            GetComponent<Image> ().sprite = cardFace;

    }

    public int CardValue {

推荐答案

第一个错误是因为方法GameObject.FindGameObjectsWithTag ("Manager");返回一个数组，并且您尝试将数组分配给非数组类型.相反，您应该使用GameObject.FindGameObjectWithTag("Manager");(注意，Object中没有's')，它仅返回与该标签匹配的第一个GameObject.

The first error is because the method GameObject.FindGameObjectsWithTag ("Manager"); returns an array and you attempt to assign the array to a non-array type. You should instead use GameObject.FindGameObjectWithTag("Manager"); (note, no 's' in Object), which returns only the first GameObject that matches the tag.

最后两个错误与第一个错误有些相关，因为它们也会返回数组.第manager.GetComponents<GameManager> ()行返回组件数组.要仅返回给定类型的第一个组件，请使用manager.GetComponent<GameManager>().

The last two errors are related somewhat to the first, since they also return arrays. The line manager.GetComponents<GameManager> () return arrays of components. To only return the first component of the given type, use manager.GetComponent<GameManager>().
