Unity 简单联网游戏(双人五子棋)开发(二)

不求甚解20018 2023-06-05 04:00:02
简介Unity 简单联网游戏(双人五子棋)开发(二)

前言:之前我们尝试开发了一个两个比拼分数的不像游戏的超简单的弱数据联网游戏,主要是想让一些没开发过联网游戏的人了解一下最基础的流程;不过有人仍然有人私信我表示看不懂,所以这次我们再开发一个类似的游戏,为了这个项目更像是一个游戏,而不是不像游戏的游戏,所以选择开发这个双人五子棋项目。

需求分析:

五子棋的规则对战规则大家都懂,我就不在这扯了,我们就只需要实现下棋,然后判断输赢就行,联网部分我们还是使用LeanCloud,好了,我们直接开始。

双人五子棋

1.准备素材

这是我找的素材,需要的自提。

2.创建项目

 Canvas里面的可以按照我这样弄,startBtn就是左上的开始按钮,Ts是右下的提示,暂时没用到,black和white是左下的黑白棋子,是用了作预制体使用的,放在上面,是为了让其大小随棋盘而变。

为了不让由于分辨率的原因而影响到下棋的位子误差,同时减少计算,棋盘高度就是Screen的高度,为了保证棋盘不应拉伸缩小而变形,我们需要一下操作

3.sdk

sdk需要去leancloud或github官网下载,这个是免费的,放心下载,然后整成我这样就行

嫌github慢可以用我的。

}

其实这个脚本可以先不用管,后面还会往里面添加联网部分,至于继承的BasePanel,主要为了省事而用的自己常用的小小框架,不喜欢的话可以自己把game脚本的获取UI的改成常规的就行

 BasePanel.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;

public class BasePanel : MonoBehaviour
{
    public Dictionary<string, List<UIBehaviour>> controlDic = new Dictionary<string, List<UIBehaviour>>();
    private bool active = true;
    public bool Active
    {
        get
        {
            return active;
        }
        set
        {
            if (active != value)
            {
                active = value;
                gameObject.SetActive(value);
            }
        }
    }

    protected virtual void Register()
    {
        FindControl<Button>();
        FindControl<Text>();
        FindControl<Image>();
    }

    protected virtual void Awake()
    {
        Register();
        //WindowsMgr.Instance.windows.Add(this.name, this);//添加到窗体管理字典
        Active = false;//默认隐藏
    }

    /// <summary>
    /// 获取UI
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="controlName"></param>
    /// <returns></returns>
    protected T GetControl<T>(string controlName) where T : UIBehaviour
    {
        if (controlDic.ContainsKey(controlName))
        {
            for (int i = 0; i < controlDic[controlName].Count; i++)
            {
                if (controlDic[controlName][i] is T)
                {
                    return controlDic[controlName][i] as T;
                }
            }
        }
        return null;
    }
    /// <summary>
    /// 将UI添加到列表
    /// </summary>
    /// <typeparam name="T"></typeparam>
    protected void FindControl<T>() where T : UIBehaviour
    {
        T[] control = this.GetComponentsInChildren<T>(true);
        string controlName;
        for (int i = 0; i < control.Length; i++)
        {
            controlName = control[i].gameObject.name;
            if (controlDic.ContainsKey(controlName))
            {
                controlDic[controlName].Add(control[i]);
            }
            else
            {
                controlDic.Add(controlName, new List<UIBehaviour> { control[i] });
            }
        }
    }


}

至此,非联网部分的已经完成了。

接下来就是将联网功能的实现,先将代码拆出来解释下吧。

 const byte GAME_OVER_EVENT = 100;
    const byte GAME_START_EVENT = 101;
    const byte HEAD_START_EVENT = 102;

这东西在Android里面应该叫做请求码,就是一个标识,需要啥的就自己定义。

  var appID = "************";
  var appKey = "******************";
  var playServer = "https://************";//你的API服务器地址

这是都是接sdk必须要有的,在leancud创建自己的应用以后可以在设置中找到。

var now = System.DateTime.Now;
var roomName = $"{now.Hour}";

var options = new RoomOptions()
        {
            EmptyRoomTtl = 10,
            MaxPlayerCount = 2,
            Flag = CreateRoomFlag.FixedMaster
        };


var res = client.JoinOrCreateRoom(roomName);
await res;

    while (res.Exception != null)
        {
            roomName = roomName + now.Hour;
            await res;
        }

这是创建或加入房间。

其他的就不说了,代码中有注释,应该都能看懂。
