using UnityEngine;
using System.Collections;
namespace CommondStructure{
public class CommandStructre: MonoBehaviour{
	Receiver receiver = new Receiver();
	ConcreteCommand command = new ConcreteCommand(receiver);
	Invoker invoker = new Invoker();
	
	invoker.SetCommand(command);
	invoker.InvokeCommand ();
}

abstract class Command{
	protected Receiver receiver;
	public Command(Receiver receiver){
		this.receiver = receiver;
	}
	public abstract void Execute();
}
public class ConcreteCommand:Command{
	public ConcreteCommand(Receiver receiver):base(receiver){}
	public override void Execute(){
		receiver.Action();
	}
}

class Receiver{
	public void Action(){
		Debug.Log("我被执行了");
	}
}	
class Invoker{
	private Command_command;
	public void SetCommond(Command command){
		this._command= command;
	}
	public void InvokeCommand (){
		_command.Execute();
	}
