General / How does the timers/clocks work?

« on: October 24, 2012, 01:03:26 am »

Hi everybody

I dont really understand the timers/clocks. I just want my game to be on 60 fps on any computer.
In Allegro, it was very very easy.... just make a variable, start it and wupti... its 60 fps.

But in SFML it seems a little more confusing to me.

i looked at the tutorial here:
http://www.sfml-dev.org/tutorials/2.0/system-time.php

But i didn't really understand it

Hope someone helps
thanks!!!!

General / help!! Loading bitmap error in sfml 2.0 :(

« on: October 21, 2012, 12:58:09 am »

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

int main()
{
        sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "Title");

        sf::Texture mytexture;
        sf::Sprite mysprite;

        mytexture.loadFromFile("theimage.bmp");

        mysprite.setTexture(mytexture, 0);

        while (Window.isOpen())
        {
                sf::Event Event;
                while(Window.pollEvent(Event))
                {
                        if(Event.type == sf::Event::Closed || Event.key.code == sf::Keyboard::Escape)
                                Window.close();
                }

                Window.clear();
                Window.draw(mysprite);
                Window.display();
                sf::sleep(sf::milliseconds(60));

        }

        return 0;
}

I cant really seem to figure it out when i look in the documentation 
When i run it, it gives me those "dot" sounds every 0.4 sec, and then there come a box where there stand i can break, continue or ignore.
In the console window there stand "failed to load image".

I have put the image in the folder where my .cpp is.

General / A little confused in the "Getting started" Tutorial

At the buttom of the page, the little test, i got everything to work.

But im confused about the nested while-loop

it looks like to me that the nested-while-loop is like an if-statement, because it go in and do the thing 1 single time, and then jump out of the loop again. I know it because i tested it with the cout thing inside the first while-loop, and it looped around 24/7.

Why not just make it to an if-statement? That would seem less confusing because then you know for sure it will do the statement 1 single time and jump out.

i actually tried to replace "while" with "if" and it worked perfectly, but why make it to a while-loop and why does it jump out?
