NPC读表对话演示.gif
对话表
TimeLine设置
读Excel表使用EPPlus.dll和Excel.dll两个库
读Excel表脚本如下，使用
using OfficeOpenXml;
using System.Collections.Generic;
using System.IO;
using UnityEngine;
public static class ExcelManger
{
public static string sPath = Application.streamingAssetsPath + "/";
static string sheetName = "Sheet1";
public static List<List<string>> Read(string path)
{
List<List<string>> list = new List<List<string>>();
FileInfo excelName = new FileInfo(sPath + path + ".xlsx");
using (ExcelPackage package = new ExcelPackage(excelName))
{
ExcelWorksheet worksheet = package.Workbook.Worksheets[sheetName];
int start = worksheet.Dimension.Start.Row;
int end = worksheet.Dimension.End.Row + 1;
int num = 1;
for (int i = start; i < end; i++)
{
if (i == start)
{
while (worksheet.Cells[i, num].Text != "")
{
Debug.Log(worksheet.Cells[i, num].Text);
num++;
}
}
else
{
List<string> strs = new List<string>();
for (int j = 1; j < num; j++)
{
strs.Add(worksheet.Cells[i, j].Text);
}
list.Add(strs);
}
}
return list;
}
}
}
读表数据结构如下
//npc对话表
class Chat
{
public string chatid;//对话id
public string npcid;//npcid
public string chatContent;//聊天内容
public string[] selet;//聊天选项
public string[] follow;//选项后续
public string[] followChatid;//后续对话id
public string[] followOpenid;//后续打开id
//构造函数
public Chat(params string[] strs)
{
this.chatid = strs[0];
this.npcid = strs[1];
this.chatContent = strs[2];
this.selet = strs[3].Split('|');
this.follow = strs[4].Split('|');
this.followChatid = strs[5].Split('|');
this.followOpenid = strs[6].Split('|');
}
}
基本逻辑脚本
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Playables;
using UnityEngine.Timeline;
public class NPC_0 : MonoBehaviour,ITimeControl
{
Dictionary<string, Chat> npcChat = new Dictionary<string, Chat>();
public PlayableDirector director;//Timeline导演
public Text nick;//对话框昵称显示
public Text chat;//对话框聊天内容显示
public Button button;//对话框按钮
public Transform selectBox;//对话框选项按钮框
string npcid = "0";//当前npcid
string chatid = null;//当前对话id
string one = null;//初始对话id
void Start()
{
//读表
List<List<string>> list = ExcelManger.Read("NPC_Chat");
for (int i = 0; i < list.Count; i++)
{
if (list[i][1] == npcid.ToString())//只保存当前npc的对话
{
npcChat.Add(list[i][0], new Chat(list[i].ToArray()));
//默认第一条
if (one == null)
{
one = list[i][0];
}
}
}
//随机npc坐标
float x = Random.Range(-10, 10);
float z = Random.Range(-10, 10);
float y = Mathf.PerlinNoise(x * 0.2f, z * 0.2f) * 5 - 5;
transform.position = new Vector3(x, y, z);
}
public void OnSignal_0()
{
//暂停
director.Pause();
//判断是否拥有对话选项
if (npcChat[chatid].selet[0] == "")
{
//没有对话选项，将对话按钮变为结束按钮
button.onClick.RemoveAllListeners();
button.onClick.AddListener(() =>
{
director.time = 0;
//关闭对话框
chat.transform.parent.gameObject.SetActive(false);
//打开玩家摄像头
UserData.cmfl.gameObject.SetActive(true);
});
}
else

for (int i = 0; i < npcChat[chatid].selet.Length; i++)
{
GameObject btn = Instantiate(Resources.Load<GameObject>("Button"), selectBox);
//按钮的名字换成选项内容
btn.GetComponentInChildren<Text>().text = npcChat[chatid].selet[i];
//注意闭包
int ii = i;

{
//点击按钮时判断后续类型
if (npcChat[chatid].follow[ii] == "0")//继续下一段对话
{
//将对话id改为指定的下一段对话id

//重新播放TimeLine
director.time = 1;
director.Play();
}
else if (npcChat[chatid].follow[ii] == "1")//打开界面
{
//继续播放
director.Play();
}

{
director.time = 0;
chat.transform.parent.gameObject.SetActive(false);
UserData.cmfl.gameObject.SetActive(true);
}
//每次点击按钮后删除所有按钮（可以使用对象池重复利用）
for (int i = 0; i < selectBox.childCount; i++)
{
Destroy(selectBox.GetChild(i).gameObject);
}
});
}
}
}
public void OnSignal_1()
{
//此处应读打开表，打开相应的功能
Instantiate(Resources.Load<GameObject>("Shop"), GameObject.Find("Canvas").transform);
}
private void OnTriggerEnter(Collider other)
{
Debug.Log("碰到了");
if (other.transform.CompareTag("Player"))
{
director.time = 0;
director.Play();
//关闭玩家摄像机 自动切换到npc摄像机
UserData.cmfl.gameObject.SetActive(false);
//设置默认第一条
chatid = one;
//对话跳过
button.onClick.RemoveAllListeners();

{
//1秒10个字，最多允许100个字
director.time = 10;
}
});
}
}
public void SetTime(double time)
{
//时间不够输出长度则逐字输出
