Class Polymorphisms problem

Quote:

Original post by shadow320 I'm compiling it I get no errors, but when I run it, I get an Send report or Don't send message.

The send or don't send happens because of a runtime error, your program compiles and links fine (which means your header files are included ok) but crashed because of something your program is trying to do - maybe trying to access a null pointer or something. Are you not running it in debug mode or as a debug build?.. Perhaps not running it through the IDE at all?

dmatter is right; likely your inclusion structure is not the issue. Can we see an example of a class or two that you're using here? What flavor of c++ are you using (i.e. g++, vs10)?

We need more to go on to help you.

Thank you for trying to help me. I work with Dev C++ and SDL. But I am doubting that it's not from the basic classes for the player and the enemy, because they worked fine before I create the code for the menu. If I use only the menu is OK but when i write the code for switching from the menu to the level and then the message starts to show. Here is the sample of the code. And again many thanks.
Sorry I don't know how to put tab in the post :(

#ifndef CMENU_H
#define CMENU_H

#include "CGameState.h"
#include "CPlayer.h"
#include "Globals.h"
#include "Functions.h"

//Class Menu;
CMenu::CMenu()
{
titleY = 480;
menuChoise = 1;
menuActive = false;
bgIMG = Load_IMG("Images\\background_img.png");
titleIMG = Load_PNG("Images\\title.png");
menuFont = TTF_OpenFont("Fonts\\spcinv_font.ttf", 32);
}
CMenu::~CMenu()
{
SDL_FreeSurface(bgIMG);
SDL_FreeSurface(titleIMG);
TTF_CloseFont(menuFont);
}

//Class World;
CWorld::CWorld()
{
bgIMG = Load_PNG("Images\\background_img.png");
Tank.SetClips();
}
CWorld::~CWorld()
{
SDL_FreeSurface(bgIMG);
}
void CWorld::handle_events()
{
while(SDL_PollEvent(&Events))
{
if(Events.type == SDL_QUIT)
{
Set_Next_State(STATE_EXIT);
}
Tank.KeyHandle();
}
}
void CWorld::logic()
{
Tank.Move();
}
void CWorld::render()
{
Apply_Surface(0,0,bgIMG,Screen);
Tank.Show();
}
#endif

You can use [ source ] tags (no spaces) to post your code with (in most cases) proper formatting.

Ah, well, there's your first mistake. Get yourself a 100% free copy of Visual C++ 2010 Express rather than that ancient DevC++ rubbish. If you're a student you can even get the Professional Edition for free.

Once you have that setup, start a new project, get your code moved across & SDL configured; and then have a go at running it. If there's a problem then the debugger should step in and give you some indication of where things went wrong.

What does the code that performs the switch look like?

OK guys I am downloading Microsoft Visual Studio 2008 because the 2010 require Service Pack 3. But I've always thought that this is only a 30 days trial. I've found where was the problem with the Don't Send message it was within the CPlayer file. In the constructor of Player class I give the X, Y, H, W a values different than 0 and this was making the problem, now I am giving them prime init and everything is set to 0. Now I don't have that problem. I declare Player object within the CWorld class and is OK but when I need to init the player object within the constructor of the CWorld class I get this error: insufficient contextual information to determine type.

And again I am sorry for the mess of the post.

This is sample from the new Player class:
class Player
{
public:
SDL_Surface *plSprite;
SDL_Rect Body;
SDL_Rect plClips[4];
Timer pTimer;
int Lifes, plFrame;
bool alive, dead;
Player();
~Player();
void plInit(int x, int y, int h, int w, bool first, bool sec);
void SetClips();
void Show();
void KeyHandle();
void CollHandle();
void Move();
};
Player::Player()
{
plInit(0,0,0,0,false,true);
plSprite = Load_PNG("Images\\tank_spr.png");
}
Player::~Player()
{
SDL_FreeSurface(plSprite);
}

And this is a sample of the World class:
class CWorld : public GameState
{
private:
SDL_Surface *bgIMG;
Player Tank();
public:
CWorld();
~CWorld();
virtual void handle_events();
virtual void logic();
virtual void render();
};
CWorld::CWorld()
{
bgIMG = Load_PNG("Images\\background_img.png");
Tank.plInit(300,200,44,26,true,false); //This is the problem line
}
CWorld::~CWorld()
{
SDL_FreeSurface(bgIMG);
}
