Call from Class created inside a Class

er4zox (4)
Hey guys !

I have 2 Classes.
-> StateManager
-> Intro

The StateManager creates the Intro. I want that the Intro calls a function of the StateManager if finished. How can I achieve that?

At line 24 at the Intro class you can see what I tried.

StateManager:

#pragma once

#include "State.h"
#include "Intro.h"

class StateManager{

private:

	std::vector <State*> States;

public:

	StateManager(){
		States.push_back(new Intro("Intro"));
	}

	~StateManager(){
		States.clear();
	}

	//Process all states
	void process(){
		for(int i=0;States.begin()+i<States.end();i++){
			States[i]->process();
		}
	}

	//Draws all states
	void draw(sf::RenderTarget& target) {
		for(int i=0;States.begin()+i<States.end();i++){
			States[i]->zeichne(target);
		}
	}

        //Add new state
        void addState(sf::String name){

          switch (name){
           case "Menu": {States.pushback(new Menu("Menu"));break;}
          }
        }

}theStateManager;

class Intro : public State{

private:

	sf::String  s_Name;
	bool finished;

public:

	Intro(const sf::String name) : s_Name  (name), finished (false) {
	}

	//Draws the intro
	void draw(sf::RenderTarget& target) const{	

	}

	//Process the intro
	void process(){

	  // >>> Thats what I tried <<<
          if(finished)theStateManager.addState("Menu");	

	}

	//Gives the name of the state
	sf::String giveName() {
		return  s_Name;
	}

};


Thanks for your help!

Store a pointe to the manager class in your state class.

How can I do that?

add a ponter member to your state|intro class and pass it in the constructor.

But how do I pass a pointer of the class itself to the constructor?

	StateManager(){
		States.push_back(new Intro("Intro", this));
