First of all, excuse my poor English = S Second, sorry, if my title is a little strange, I did not know how to formulate it better.
I have a little problem. I am developing a game in Java, and I am using the MVC pattern the way I was taught. I don’t know if this is the most efficient way, but, in any case, here’s the general thing: 4 packages: model, view, controller and "observer".
There is one “Observer” interface in the observer, in which all the methods that the element “monitor the model” should implement are defined. There is also an Observable class with a list of observers and in all ways that notify them of some changes (methods such as "fireEvent1 (int i) {for (Observer obs: observers) obs.Event1 (i);}") The model extends the class Observable, and some GUI elements implement the Observer interface.
Now my problem: in the method in the model, I want the model to “wait” for 2 user interactions. This means something like this:
- method invoked in the model
- do something.
- wait for the user to interact for the first time
- get information about what the user has just done (which is assembled in the controller)
- do something.
- ,
- do stuff

}

Observable and Observer classe/interface:
public class Observable {
private LinkedList<Observer> observers = new LinkedList<Observer>();
public void addObserver(Observer obs) {
observers.add(obs);
}
public void fireWaitForActions(boolean b) {
for (Observer obs: observers) obs.waitForActions(b);
}
}
public interface Observer {
public void waitForActions(Boolean b);
}
