Right it works, but only with the sf::Image&

may is ask what the & does?As i know it gives the adress to an object, and therefore should work as a pointer, but obviously not...

Well,what exactly do you mean by return a reference directly.  I interpreted it as to remove the pointer, but that seem to be wrong :/


i added  image[position] = new Image(); aswell
 

}

I want to have a class where i stora all my images like this

Code: [Select]

#ifndef GAMESTATE_H_INCLUDED
#define GAMESTATE_H_INCLUDED

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>

#include <string>
using namespace std;
class Model;

class Gamestate{
  private :
    Model* model;
    sf::Image *image[255];
    sf::Music bgm[1];
    sf::SoundBuffer sfx[255];




    public :
    Gamestate(Model* model);
    void DrawGamestate(sf::RenderWindow* App,int layer);
    void UpdateGamestate();
    void HandleEvent( sf::Event* event);

    void LoadImage(string address, int position);
    void LoadSfx(string address,int position);
    void LoadMusic(string address,int position);
    sf::Image *GetImage(int position);

};
#endif // GAMESTATE_H_INCLUDED

Code: [Select]

#include "Gamestate.h"

#include "Model.h"

Gamestate::Gamestate(Model* model){
    this->model = model;
    this->LoadImage("testbg.png",0);
}
void Gamestate::DrawGamestate(sf::RenderWindow* App, int layer){
    }

void Gamestate::UpdateGamestate(){
}
void Gamestate::HandleEvent(sf::Event *event){
}


void Gamestate::LoadImage(string address, int position){
    image[position]->LoadFromFile(address);

}

void Gamestate::LoadSfx(string address,int position){
    sfx[position].LoadFromFile(address);

}

void Gamestate::LoadMusic(string address,int position){
    bgm[position].OpenFromFile(address);

}
sf::Image *Gamestate::GetImage(int position){
    return image[position];
}

I want to be able to load it like this
sf::Sprite bg1(hej->GetGamestate()->GetImage(0));

But its not possible -> D:\Program\Projects\test\Game.cpp|48|error: no matching function for call to 'sf::Sprite::Sprite(sf::Image*)'|

It doesnt take pointers... So its not possible to store my images in another class and get them from another?

Hello, when i call my drawgame function in the following code it just paints a white square where the picture are supposed to be. the square have the right proportions and such its just white...

Code: [Select]

#include "Gamestate.cpp"
#include "Player.cpp"
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
#include <SFML/System.hpp>
using namespace std;
class Model {

private :
int hej;
Gamestate* gamestate;
Player* player;
sf::Sprite Sprite1;

public :

Model();


void updategame();

void drawgame(sf::RenderWindow *App);

};

Model::Model(){

         sf::Image Image1;
        Image1.SetSmooth(false);
        Image1.LoadFromFile("trans.png");
        Sprite1.SetImage(Image1);
        Sprite1.SetPosition(500,-1);
}




void Model::drawgame(sf::RenderWindow *App){



     Sprite1.SetPosition(500,-1);
     App->Draw(Sprite1);


}



Also it works fine if I load the picture in the drawgame function

Code: [Select]

void Model::drawgame(sf::RenderWindow *App){
    sf::Image Image1;
        Image1.SetSmooth(false);
        Image1.LoadFromFile("trans.png");
        sf::Sprite Sprite1(Image1);
        Sprite1.SetPosition(500,-1);



     App->Draw(Sprite1);


}

Yes it was that "set smooth" was set to true... one might wonder why that is the defualt setup when it works so bad O_o

Graphics / Help with scrolling background

« on: June 01, 2010, 09:29:32 pm »

Hello.
So i want a scrolling background. I get the background to scroll fine there is just one problem, there is a pixel gap.

http://data.fuskbugg.se/skalman01/-help.png



   

Code: [Select]

sf::Sprite bg1(background);
    sf::Sprite bg2(background);
    int bgheight;
    bgheight = 1904;
    bool bgActive1;
    bool bgActive2;
    int bgPosition1;
    int bgPosition2;
    bgPosition1 = 799;
    bg1.SetPosition(0,(bgPosition1-bgheight));
    bgActive1 = true;
    bgActive2 = false;


 // Start the game loop
     while (App.IsOpened())
     {
         if(App.GetFrameTime() < 0.0167){
             Sleep((0.0167-App.GetFrameTime())*1000);
         }
         // Process events
   

         if(bgActive1 == true){

             bgPosition1 = bgPosition1 + 1;
             bg1.SetPosition(0,(-bgheight+ bgPosition1));
         }
          if(bgActive2 == true ){

             bgPosition2 = bgPosition2 + 1;
             bg2.SetPosition(0,(-bgheight+ bgPosition2));
         }
          if((-bgheight+ bgPosition1) == 0 && bgActive1 == true){
                  bgActive2 = true;
                  bgPosition2 = 0;
                 bg2.SetPosition(0,-bgheight+ bgPosition1);

          }
     //     if((-bgheight)+ bgPosition1 == 800 && bgActive1 == true){
      //           bgActive1 = false;
       //      }
        if((-bgheight+ bgPosition2) == 0 && bgActive2 == true){
                  bgActive1 = true;
                  bgPosition1 = 0;
                 bg1.SetPosition(0,-bgheight+ bgPosition2);

          }
       //   if((-bgheight)+ bgPosition2 == 800 && bgActive2 == true){
        //         bgActive2 = false;
         //    }


/ Clear screen
         App.Clear();

       
            if(bgActive1 == true){
           App.Draw(bg1);
           }
           if(bgActive2 == true){
          App.Draw(bg2);
           }

           if(bgActive2 == true && bgActive1 == true){
               m++;
               if(m == 5){
               cout << endl << bgPosition1 << endl;
               cout << bgPosition2 << endl;

           }
           }

                   // Draw the string
        // App.Draw(Text);

         // Update the window
         App.Display();


     }

     return EXIT_SUCCESS;
 }


The picture is 1904 pixels in the y axis

I dont see where my thinking fails...
