C++ :: OpenGL Preserve States (SFML)
Feb 12, 2013
So I did read, however it said also that it was memory intensive and I had a question... I also came across this:
Window.pushGLStates();
Window.draw("Sfml Text");
Window.popGLStates();
The problem here is that none of these commands exist!
Window.draw should exist and even though I have all the proper includes I still get it telling me that 'Draw' is not a member of sf::Window
I have encountered that error many times everywhere across my sfml related code, it's not like they removed all those features in the update (Which they did not) but, why then would it not be a member?

I have a GPIO pin(GP4) on a microcontroller with a continuous digital pulse train coming into it. I am writing to it in C and do not have interrupts on this chip. I have been calling my input "#define inputA GP4". In C, I would like to be able to find the positive edge of a pulse and trigger the timer on it. I'm not sure if an XOR will accomplish what I need by storing inputA to another variable at some point. Would it be possible to accomplish this by writing code that acts like a positive-edge triggered flip-flop?
The other problem that I have is I need to be able to do this and not get caught in an infinite loop where I can still do other things sequentially with my code, if for instance, inputA goes to 0 and stays at 0 permanently. This means that my option of using while(inputA=0); is out of the question.

I use visual studio 2012. When I asked what I should use in order to put graphics into my program, I was told by the community that SFML works well. My only problem is that now I have SFML, where and how do I unpack it?

so im trying to make a blinking cursor to give it a terminal feel, but it is speradic, since it is going at cycles instead of seconds. how can i fix this?

So I have the following code using [URL] ..... It compiles correctly, but does not display the map on the screen. Is it an issue with my code or an issue with the map file itself?

#include <SFML/Window.hpp>
#include <level.h>
int main(){
sf::RenderWindow window(sf::VideoMode(640, 480), "");

So this is my first try animating on my own, without a reference right in front of me. It's not working, I did check some of the projects I've made in the past, but for one those were done with Allegro, and really it should be able to move over to SFML quite easily, but it's not. It does display on the window in the correct place, but there are 3 pictures in the file and I want it to cycle through them, but it shows all three at the same time, and it only works once. if I press space a second time, only one of the pictures shows up, and it doesn't cycle at all. Here is my .cpp file :
#include "headers.h"
#include "SwordSprite.h"
int top = 0;
int left = 88;
int right = 132;
int bottom = 35;
SwordSprite::SwordSprite() {
[Code] .....

Any way in sfml of changing the font style and/or size used in the window title for RenderWindow?
As a secondary point - can the colour and size of the title bar itself be changed?

I am trying to position and sf::Text relatively to another sf::Text. Not over, or beneath or anything like that, but after- like so:
theTexts.push_back(UnitOfText(Text(outputstring,defaultFont, 15),theColor));
int i = (theTexts.size() - 1);
std::cout << i;
sf::FloatRect textRect ( theTexts[i].theText.getLocalBounds() );
theTexts[i].theText.setOrigin (textRect.width / 2, textRect.height / 2);
if(theTexts.size() > 1)
{
theTexts[i].theText.setPosition(theTexts[i - 1].theText.getLocalBounds().left,theTexts[i - 1].theText.getLocalBounds().top);
}

I'm currently just trying C++ with SFML. So I've installe SFML 2.0 for Visual C++ 2010 Express 64 bit, and I get an error while trying to run the debug of my code.
//Libraries
#include <SFML/Graphics.hpp>
#include <iostream>
int main() {
sf::RenderWindow window(sf::VideoMode(1280, 720),"SFML Game1");
return 0;
}
And this is the result I'm getting when trying to run it

So I am writing a map generation algorithm (with SFML), and it seems the problem is in here:
Sprite sprites[32][32];
void genmap(){
Texture grasstiletex;
grasstiletex.loadFromFile("data/grasstile.png");
[Code] .....
But when I run it I get: Unhandled exception at 0x69791f34 in sfmlproject.exe: 0xC0000005: Access violation reading location 0x001b5000.

Is there any way in sfml version 2 that I can get objects in a graphics window to retain there relative positions and sizes when the window is resized? I have tried looking in the documentation for version 2 but with no luck.
As an example suppose the window is 800x600 and there is a line running right across the window at 3/4 of the way down (i.e at y=450). If the window is then made larger say 1280x1024 how would I keep the line in the same relative position (i.e all the way across 1280 and 3/4 of the y setting down).

I'm trying to make a menu object in SFML. So far all I've added is the ability to add buttons with text inside of them. I store the buttons in a vector and then loop through that vector to draw the buttons.
The error stems from line 24 of the 2nd piece of code.
Here's what I've got:
//MenuTest.h
#include <SFML/Graphics.hpp>
#include <string>
#include <vector>
class Menu1 {
class Button1 {
sf::RectangleShape body;
[Code] ....
This causes an error at the line window.draw(text); in Menu::Button::drawButton(). With the error "Access violation reading location (some memory address)".
Everything up to trying to draw the text works fine.
