一个简单 小型的C#Socket网络通信库 聊天室示例(五)

讲完了 聊天消息了 下面说两个主界面 还有工具类

这里懒得再转****Sprite直接用RawImage了 他可以放Texture2D

登录界面 LoginPanel

应该没啥说的 就建这几个组件

代码：

using UnityEngine;
using UnityEngine.UI;

public class LoginPanel : MonoBehaviour 
{

    public InputField NameInput;

    public RawImage PlayerHead;

    public Button LoginBtn;

    public Button SelectHeadBtn;

}

聊天界面ChatPanel

每个聊天消息框都是由SpawnDialogUI这个函数进行创建的 创建完要下拉最下面消息框嘛 所以要更改Content的位置进行下拉操作

代码：

using UnityEngine;
using UnityEngine.UI;

public class ChatPanel : MonoBehaviour 
{
    public Button SendChatBtn;

    public RawImage HeadImg;

    public Text PlayerNameTxt;

    public RectTransform DialogParent;

    public DialogUI DialogUIPrefab;

    public InputField chatInput;

    /// 

    /// 生成对话框  懒得写枚举了。用int吧  0我方 其他对方
    /// 
    /// 
    /// 
    public DialogUI SpawnDialogUI(string playername, string info,Texture2D  head, int i=0)
    {

        DialogUI dialogUI;
        if (i==0)
        {
             dialogUI = Instantiate(DialogUIPrefab, DialogParent.transform).InitLocalDialog(playername, info, head);
        }
        else
        {
            dialogUI = Instantiate(DialogUIPrefab, DialogParent.transform).InitDialog(playername, info, head);
        }
        //下拉对话框 上面应该会延时 所以这里也需要延时
       Invoke("HaulDown",0.02f);

        return dialogUI;

    }

    public void HaulDown()
    {
        DialogParent.anchoredPosition = new Vector2(DialogParent.anchoredPosition.x, DialogParent.sizeDelta.y);
    }
}[/mw_shl_code] 

**工具拓展类 ****ImageExtension**

ByteToTexture 就是Byte转成Texture2D图片
LoadImage 是RawImage 加载Byte[]数据的图片

**代码：**[mw_shl_code=csharp,false]using System.IO;
using UnityEngine;
using UnityEngine.UI;

public static class ImageExtension  
{
    public static void LoadImage(this RawImage rawImage,byte[] data,int Width=200,int Height=200)
    {
        Texture2D texture2D = new Texture2D(Width, Height);
        texture2D.LoadImage(data);
        rawImage.texture = texture2D;

    }

    public static Texture2D ByteToTexture(this byte[] data, int Width = 200, int Height = 200)
    {
        Texture2D texture2D = new Texture2D(Width, Height);
        texture2D.LoadImage(data);
        return texture2D;

    }

    /// 

    /// 路劲图片文件转byte[]
    /// 
    /// 
    /// 
    public static byte[] GetPictureBytes(this string filename)
    {
        FileInfo fileInfo = new FileInfo(filename);
        byte[] buffer = new byte[fileInfo.Length];
        using (FileStream stream = fileInfo.OpenRead())
        {
            stream.Read(buffer, 0, buffer.Length);
        }
        return buffer;
    }

}

好了我们下篇最后一篇继续 基本功能都写在了GameRoot那 =。=
