NGUI 对话系统

前言

对话面板属于剧情系统中的一环，单独做成一个prefab，放在resource文件下，在用到的时候，读取。

简单界面

首先创建类，对话要有人，要显示对话人的信息，对话要有内容，同时和对话人联系上，简单说就是哪个人说了哪句话，下面改哪个人说哪句话

//存放对话中出现的人物的信息public class TalkRoleData{    public List<TalkRoleDataEntity> datas = new List<TalkRoleDataEntity>();}public class TalkRoleDataEntity{    public int Id;   //id    public string icon;//人物图标    public string name;//人物名称//可继续添加信息，取决于需求}

//存放对话public class TalkData {    public List<TalkDataEntity> datas = new List<TalkDataEntity>();}//说话的内容public class TalkDataEntity{    /// <summary> 对话id，</summary>    public int talkId = 0;    /// <summary> 0：对话时位于左边，1：右边</summary>    public int talkSide = 0;    /// <summary> 对话内容 </summary>    public string talkText = "";    /// <summary> 对话人物的ID <span style="font-family: Arial, Helvetica, sans-serif;">和对话人联系起来</span> </summary>    public int talkRoleid = 0;    /// <summary> 对话时的效果 </summary>    public string talkeffect="";//后续可继续扩展}

下面是对话脚本，常规的流程是: 面板上，文字渐渐的出现，当点击时，全部出现，（面板上出现继续点击的提示），再次点击后，进行接下来的对话，（会有跳过对话的功能）

   public UILabel text,name0,name1;    public int talkId = 0;    public int talkIndex = 0;    public List<int> talkSide;    public List<string> talkText;    public List<TalkRoleDataEntity> talkRole;    public List<string> talkIcon;    public List<string> talkName;    public List<string> talkEffe;    public float textProc = 0;    string texttotal;    public float textspeed = 0.5f;    int tempProc;//上一次字到达的位置// Use this for initialization  void Start () {        if (talkId > -1) ReseTalkData();        ChangeTalk(0);}// Update is called once per framevoid Update () {        if (Input.GetMouseButtonUp(0))//点击的时候有两种效果，一种是话没说完加速，一种是话说完了，说下一句        {            if (text.text.Length < texttotal.Length)//没有说完            {                textProc += 9999;            }            else            {                if (talkIndex >= talkText.Count - 1)//对话结束                {Hide();//对话消失                    return;                }                else ChangeTalk(talkIndex + 1);//继续下一句对话            }        }        showOneChar();}//逐渐显示文字    void showOneChar()    {        if (text.text.Length < texttotal.Length)//没有显示完        {            textProc += textspeed;

                       nowProc += (lenc - tempProc);                        textProc += (lenc - tempProc);                        tempProc += (lenc - tempProc);                        showOneChar();                        break;//对于转义符\n 等的处理                    case @"\":                        if (texttotal.Substring(tempProc, 2) == @"\n") text.text += "\n";

总结

基于NGUI的简单的对话系统
