场景中人名显示

//这只是个简单实现，发现shader方面不应该用U中自带的文本shader，因为那个太透了。。需要完善的地方还很多，等需要的时候再好好写一下 ^.^

//作用：在物体头上显示一串文本，跟着主相机旋转。可以用偏移来设置其位置。

using UnityEngine;
using System.Collections;

public class NameTip : MonoBehaviour
{
    public string Text="";//内容
    public Vector3 TextOffset=new Vector3(0,1,0);//偏移
    public Color TextColor = Color.green;//字符颜色
    public Font TextFont;//字体
    private GameObject go;
    void Start () {
        Font font = Resources.Load("Fonts/SIMHEI") as Font;
        //设定承载字符的物体
        go = new GameObject("TipText");
        go.AddComponent(typeof(TextMesh));
        go.AddComponent<MeshRenderer>();
        go.renderer.material = font.material;
        go.renderer.material.color = TextColor;
        go.transform.parent = gameObject.transform;
        go.transform.localPosition = Vector3.zero + TextOffset;
        //设置字符的样式
        TextMesh txt = go.GetComponent<TextMesh>();
        txt.text = Text;
        txt.characterSize = 0.2f;
        txt.anchor = TextAnchor.UpperCenter;
        txt.alignment = TextAlignment.Center;
        txt.font = font;
      }
      // Update is called once per frame
      void Update () {
              go.transform.LookAt(Camera.mainCamera.transform.position);
     go.transform.Rotate(0, 180, 0);
