      Sorry for this question because sure that it is a stupid question.
      I'm using STL in my class, and i have created a vector.
      But when i want to use a iterator, problems appear.
      `arrayBoton' undeclared (first use this function)
      The code is in spanish

      C Source Code

      1. // iVentana.h (iWindow in english ;) )
      2. #ifndef IVENTANA_H
      3. #define IVENTANA_H
      5. #include "Boton.h"
      6. #include <vector>
      7. #include <algorithm>
      9. using namespace std;
      11. class iVentana
      12. {
      13. public:
      14. iVentana(int nI, int nB);
      15. ~iVentana();
      16. void dibujar(SDL_Surface *screen);
      17. void insertarBoton(Boton *b);
      18. void insertarFrame(CFrame *f);
      19. struct DeleteMemObj
      20. {
      21. template<typename T>
      22. void operator()(const T* ptr) const
      23. {
      24. delete ptr;
      25. ptr = NULL;
      26. }
      27. };
      29. protected:
      30. CSprite *Cimagen;
      31. vector<Boton*> arrayBoton;
      32. int activa, nframes;
      34. };

      Source Code

      1. #include "iVentana.h"
      3. iVentana::iVentana(int nI, int nB):activa(0), nframes(0)
      4. {
      5. Cimagen = new CSprite(nI);
      6. arrayBoton.reserve(nB);

      14. {
      15. this->Cimagen->addframe(*f);
      16. }
      17. void iVentana::insertarBoton(Boton *b)
      18. {
      19. this->arrayBoton.push_back(b);
      20. }
      22. void dibujar(SDL_Surface *screen)
      23. {
      24. for(vector<Boton*>::iterator it = arrayBoton.begin(); it != arrayBoton.end(); it++) //the problem is here
      25. {
      26. if((*it) != NULL)
      27. {
      28. (*it)->dibujar(screen);
      29. }
      30. }
      31. }

      If anything in the code isn't understood tell me.
      Thanks.

    • Your function dibujar(SDL_Surface *screen) needs to have the prefix iVentana:: on it ie.

      Source Code

      1. void iVentana::dibujar(SDL_Surface *screen)
      2. {
      3. for(vector<Boton*>::iterator it = arrayBoton.begin(); it != arrayBoton.end(); it++) //the problem is here
      4. {
      5. if((*it) != NULL)
      6. {
      7. (*it)->dibujar(screen);
      8. }
      9. }
      10. }


      Otherwise the compiler thinks you are just making a function called 'dibujar' in the global namespace

    • If it makes you feel better, I just spent 30 minutes trying to figure out why I was getting None return back for all content set utility scores. Turns out the bug was in this function:

      Source Code

      1. @classmethod
      2. def _get_subaction_content_set_utility_score(cls, content_score):
      3. """
      4. Return the utility of the content set score.
      5. """
      6. if content_score is None:
      7. return None
      8. cls.SUBACTION_AUTONOMY_CONTENT_SCORE_UTILITY_CURVE.get(content_score)


      No matter how experienced you get, you can still make those little stupid mistakes.

    • RE: question

      I was also going to post some silly code that drove me nuts for about 4 hours, but then again, I am a newbie so I guess there is no need for that. Lol.

      It does make me feel better knowing that I'm not the only one that this happens to!

      PS. I speak more Spanish than English and I though I would never see code written in Spanish..... nice coding Budark!

      We haven't announced the game so all I can say is that it's a sims game, which doesn't really help you. The last sims game I worked on was medieval.

    • Our whole half of our first term was about working at a company and non disclosure stuff, so I understand :D.

    • Yep, that's par for the course. When we're announced, I'll happily post a link to the announcement and answer whatever questions I'm allowed to about it. :)
