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 datas = new List();
}
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 datas = new List();

}
//说话的内容
public class TalkDataEntity
{
    /// 
 对话id，
    public int talkId = 0;
    /// 
 0：对话时位于左边，1：右边
    public int talkSide = 0;
    /// 
 对话内容 
    public string talkText = "";
    /// 
 对话人物的ID 和对话人联系起来 
    public int talkRoleid = 0;
    /// 
 对话时的效果 
    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）

总结

基于NGUI的简单的对话系统
