public class Script : MonoBehaviour {
    public GameObject[] characterPrefabs; //人物的预设体
    private GameObject[] characterGameObjects; //把人物装进一个数组里
    private int selectedIndex = 0; //当前选择的人物是第几个
    private int length;    //所有可供选择的角色个数

// Use this for initialization
void Start () {
        length = characterPrefabs.Length;
        characterGameObjects = new GameObject[length];
        for (int i = 0; i < length; i++)
        {
            characterGameObjects[i] = GameObject.Instantiate(characterPrefabs[i], transform.position, Quaternion.identity) as GameObject;
        }
        UpdateCharacterShow();
}

// Update is called once per frame
void Update () {

}
    void UpdateCharacterShow() //更新所有角色的显示
    {
        characterGameObjects[selectedIndex].SetActive(true);
        for (int i = 0; i < length; i++)
        {
            if (i!=selectedIndex)
            {
                characterGameObjects[i].SetActive(false);   //把未选择的角色设置为隐藏
            }
        }
    }

    public void OnNextButtonClick() //当我们点击了下一个按钮
    {
        selectedIndex++;
        selectedIndex %= length;
        UpdateCharacterShow();
    }
    public void OnPrevButtonClick()//当我们点击上一个按钮
    {
        selectedIndex--;
        if (selectedIndex==-1)
        {
            selectedIndex = length - 1;
        }
