unity如何实现角色的选择

如何实现角色的选择：创建一个空物体加上脚本CharacterCreation


public class CharacterCreation : MonoBehaviour {
    public GameObject[] characterPrefabs;
    private GameObject[] characterGameObjects;
    private int selectedIndex = 0;
    private int length;//所有可供选择的角色个数 
void Start () {
        length = characterPrefabs.Length;
        characterGameObjects = new GameObject[length];
        for (int i=0;i<length;i++) {
            characterGameObjects[i] = GameObject.Instantiate(characterPrefabs[i],transform.position, transform.rotation) as GameObject;
        }
        UpdateCharacterShow();
    }

    void UpdateCharacterShow()//更新所有角色的显示
