【Unity】一个消息框架例子
框架实现：
定义消息类：
public class Msg1
{
public byte Type;
public int Command;
public object Obj;
public Msg1() { }
public Msg1(byte Type_, int Command_, object Obj_)
{
this.Type = Type_;
this.Command = Command_;
this.Obj = Obj_;
}
}
public class Msg1Type
{
public static byte Type_Audio = 1;
public static byte Type_UI = 2;
}
public class Msg1Command
{
public static int Command_PlayAudio = 101;
public static int Command_AddScore = 201;
}
定义MonoBase类：
public abstract class MonoBase1: MonoBehaviour
{
//发送消息
public void SendMsg(byte Type, int Command, object Obj)
{
Msg1 msg1 = new Msg1(Type, Command, Obj);
SendMsg(msg1);
}
public void SendMsg(Msg1 msg)
{
MessageCenter1.SendMsg(msg);
}
//接收消息
public virtual void ReceiveMsg(Msg1 msg1) { }
//分发消息
public virtual void DistributeMsg(Msg1 msg1) { }
}
定义消息中心类：
public class MessageCenter1
{
public static List
public static void AddManagerToList(MonoBase1 monoBase1)
{
if (!managerList.Contains(monoBase1)) managerList.Add(monoBase1);
}
//给所有的管理类发送消息
public static void SendMsg(byte Type, int Command, object Obj)
{
Msg1 msg1 = new Msg1(Type, Command, Obj);
SendMsg(msg1);
}
public static void SendMsg(Msg1 msg1)
{
foreach (MonoBase1 monoBase in managerList) monoBase.ReceiveMsg(msg1);
}
}
定义管理器基类：
public abstract class ManagerBase1
{
private static T instance;
public static T Instance { get => instance; }
public List
protected byte msgType;
private void Awake()
{
instance = this as T;
SetMsgType();
MessageCenter1.AddManagerToList(this);
}
//将MonoBase添加至receiveList
public void AddToReceiveList(MonoBase1 monoBase1)
{
if (!receiveList.Contains(monoBase1)) receiveList.Add(monoBase1);
}
//设置可接受的消息类型
public abstract void SetMsgType();
//接收消息
public override void ReceiveMsg(Msg1 msg1)
{
if (msg1.Type == msgType)
{
DistributeMsg(msg1);
}
}
//分发消息
public override void DistributeMsg(Msg1 msg1)
{
foreach(MonoBase1 monoBase1 in receiveList)
{
monoBase1.ReceiveMsg(msg1);
}
}
}
使用框架实例：
Player触碰到Coin，Coin发送消息使得分数显示增加
Player挂载：
public class PlayerControllerMsg1: MonoBehaviour
{
private void Update()
{
float vertical = Input.GetAxis("Vertical");
float horizontal = Input.GetAxis("Horizontal");
Vector3 dir = new Vector3(horizontal, 0, vertical);
if(dir != Vector3.zero)
{
transform.rotation = Quaternion.LookRotation(dir);
transform.Translate(Vector3.forward * 3 * Time.deltaTime);
}
}
}
Coin挂载：
public class CoinController: MonoBase1
{
private void OnTriggerEnter(Collider other)
{
if(other.tag == "Player")
{
SendMsg(Msg1Type.Type_UI, Msg1Command.Command_AddScore, 1);
Destroy(gameObject);
}
}
}
Canvas挂载：
public class UIManagerOfMsg1 : ManagerBase1
{
public override void SetMsgType(){ this.msgType = MsgType.Type_UI; }
}
分数面板挂载：
public class ScorePanel: MonoBase1
{
public Text text;
private void Start() { UIManagerOfMsg1.Instance.AddToReceiveList(this); }
public override void ReceiveMsg(Msg1 msg1)
{
if(msg1 != null && msg1.Command == Msg1Command.Command_AddScore)
{
int score = int.Parse(text.text) + 1;
text.text = score + "";
}
}
}
