Unity3D效果实现：文字对话

逻辑：按下鼠标左键，人物表情切换，文字切换

脚本代码：需要一个消息管理类和消息类

消息管理类：

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class MessageManager : MonoBehaviour
{
    //背景图
    public Image Bgimage;
    //头像图像
    public Image headImage;
    //讲话人
    public Text NameText;
    //内容
    public Text ContentText;
    //储存消息
    public List messages;
    //消息索引
    private int index = 0;
    void Start()
    {
        messages = new List();
        Message msg = new Message() { Name = "小黄", Content = "请问探险森林怎么走？", ImageName = "ShayHead" };
        messages.Add(msg);
    }

    Message GetMessage()
    {
        if(index(msg.ImageName);
                NameText.text = msg.Name;
                ContentText.text = msg.Content;
            }
            if(msg.type==MessageType.BackGround)
            {
                Bgimage.sprite = Resources.Load(msg.BackGround);
                Message();
            }
        }
    }
}

　　消息调用类：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//枚举类型，判断是更改消息还是背景
public enum MessageType
{
    Message,
    BackGround
}
public class Message
{
    //枚举类型，默认为对话类型
   public MessageType type = MessageType.Message;
    public string Name;
    public string Content;
    public string ImageName;
    public string BackGround;
}
