Unity角色對話

對話類---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class word {
public int state;//對應的劇情狀態
public string[] sentence;//角色雙方說的每句話
public int[] roleOrder;//每句話對應的角色，好吧暫時用不上
}

//對話類，點擊I鍵觸發對話，每一句話會以每隔一小段時間片顯示一個字符的形式顯示，讀完該句話之后，再點擊I鍵跳轉到下一句，如果沒有句子了，那么
//結束對話，對話的相應句子映射到場景控制器類中，場景控制器根據當前的場景狀態設置對話框的顯示與否，並且將讀取的句子填充到對話框中
//句子列表表示不同的劇情狀態下的對話內容
//通過繼承對話類，對話的對象可以是npc，也可以是任何可以觸發對話的物體
