General / Re: Fps switches between 60 and 50

« on: May 10, 2014, 10:07:32 pm »

Thanks for your post, will try some solution with delta time instead.
I use new/delete out of habit I guess, no need to worry about about stack memory limit

General / Fps switches between 60 and 50

« on: May 10, 2014, 09:02:54 pm »

Hello.
Im trying to run my main loop at a static 60 fps, but sometimes it decides to limit the fps to 50. I guess this problem could be caused by many reasons, I have checked my cpu speed and seems to be running at full clockspeed. Any ideas?

#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include "model.h"
#include <iostream>
int main() {
    sf::RenderWindow window(sf::VideoMode(1024, 768), "Azyrium");

    Model * model = new Model();
    sf::Clock clock;
    sf::View view2;
    view2.setSize(1920,1080);
    view2.setCenter(960,540);
    window.setView(view2);
    while (window.isOpen()) {
        clock.restart();
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                window.close();
            }
            else if (event.type == sf::Event::KeyPressed || event.type == sf::Event::KeyReleased ) {
                model->handleInput(event);
            }
        }
        model->updateGame();
        window.clear();
        model->drawGame(window);
        window.display();
        while (clock.getElapsedTime().asMicroseconds() < 16667) {
            sf::sleep(sf::microseconds(16667-clock.getElapsedTime().asMicroseconds()));
            std::cout << 1/((double)(clock.getElapsedTime().asMicroseconds())/1000000 ) << std::endl;
        }

    }
    delete model;
    return 0;
}

Main loop.

General / Problem when replacing sdl with sfml, kinda :)

Ye well thats probably true.

Anyway i have narrowed down the problem

Code: [Select]

#include "SDL.h"
#include <string>
#include "Gamestate.h"
#include "SDL_mixer.h"
#include "SDL_image.h"
#include <SFML/Graphics.hpp>
 #include <SFML/Audio.hpp>
#include <SFML/System.hpp>
using namespace std;

#ifndef SELECTSCREEN_H
#define SELECTSCREEN_H
//class Model;

class SelectScreen: public Gamestate{
      private:
      sf::Sprite background1;
      sf::Sprite startbutton1;
      sf::Sprite quitbutton1;
      sf::Sprite buttonunderline1;
      sf::Sprite optionsbutton1;
      sf::Sprite continuebutton1;

   





      public:

             SelectScreen(Model *lol);

            ~SelectScreen(){}

           void drawStagelow(sf::RenderWindow  *screenen);
           void handleinput(bool keys[10]);
           void updateStage();
           sf::Sprite getSprite(){return background1;}


      };





#endif

Code: [Select]

            SelectScreen::SelectScreen(Model *lol) : Gamestate(lol){


                       sf::Image Image;
    Image.LoadFromFile("backgrounds/selectscreen.bmp");
     background1.SetImage(Image);

}

Code: [Select]

            void SelectScreen::drawStagelow(sf::RenderWindow  *screenen){
                 sf::Image Image;
    Image.LoadFromFile("backgrounds/selectscreen.bmp");
     sf::Sprite Sprite1;

     Sprite1.SetImage(Image);


               //dont work   screenen->Draw(background1);
               
               
               //work        screenen->Draw(Sprite1);




     

                       }
I find it weird that only one of them work.

The events shouldnt effect the window?
Its not a global variable, im sending it as a parameter

model->drawAll(app);

Why am i hiding the problem?
I got it to work with codeblocks when i followed the tutorial.I just couldnt find the place to add SFML_DYNAMIC. in devc++.

I had to  switch form devc++ to code blocks to get it work =P

Hello


First i create the app window, and then send the window to another class that are supposed to draw something on it.But the window is blank when i run the program.
I can see the image if I make some ugly code and draw an image in the main loop.

Code: [Select]

#include "SDL.h"
#include <string>
#include "Window.h"
#include "Model.h"
#include "SDL_mixer.h"
#include "SDL_ttf.h"
#include <SFML/Graphics.hpp>
 #include <SFML/Audio.hpp>
#include <SFML/System.hpp>



using namespace std;


int main( int argc, char* args[] )
{
        if( SDL_Init( SDL_INIT_EVERYTHING ) == -1 )
    {
        return 1;
    }


    //Initialize SDL_ttf
    if( TTF_Init() == -1 ){
         return false;
         }
    Mix_OpenAudio( 44000, MIX_DEFAULT_FORMAT, 2, 4096 );
    sf::RenderWindow *app;
    app = new sf::RenderWindow(sf::VideoMode(800, 600), "SFML window");
     //(sf::VideoMode(800, 600), "SFML window");

    Model *model = new Model();
 //   Window *theWindow = new Window(800,600,model);
    SDL_Event event;
    bool keysHeld[10] = {false};
  //  bool keyPulses[10];
  //  keyPulses[4] = true;
    long start;
 //   SDL_ShowCursor(SDL_DISABLE);


    sf::Image Image;
    Image.LoadFromFile("backgrounds/selectscreen.bmp");
     sf::Sprite Sprite1;

     Sprite1.SetImage(Image);

     // Sprite(Image);




    while( model->quitcheck() == false )
    {

        //If there's an event to handle
        if( SDL_PollEvent( &event ) )
        {

Hello

When i try to add the following to my program

Code: [Select]

sf::Sprite test;

It replies

  variable 'vtable for sf::Sprite' can't be auto-imported. Please read the documentation for ld's --enable-auto-import for details.

What am I doing wrong.

I can use the following without a problem(that i know of)

Code: [Select]

sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window");

 sf::Image Image;
 Image.LoadFromFile("backgrounds/selectscreen.bmp");
