Window / One action per isKeyPressed

« on: September 28, 2014, 05:43:09 pm »

Hello,

Here is the problem I have , I want to make something move from one lane to another , for that in a loop for window.isOpen() in the pollEvent loop I use this code , wich seemed pretty good to me :

            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Up)){
                player.moveLane(UP);
            }
            if(sf::Keyboard::isKeyPressed(sf::Keyboard::Down)){
                player.moveLane(DOWN);
            }
 

But the problem here is that on the next occurence of the isOpen loop , it will try again to move , so the player moves twice , while pressing one key. So my idea was too make the player move one lane when pressing the key , how do you do that if this code doesn't work ?

And thhanks to anyone looking here

Ok so If I have just my GPU activated I get a SIGSEGV in the SFML code Oo :

And AMD Catalyst says now that My drivers are bugged.....

EDIT : When I deactivated my AMD Car my laptop did a BSOD

My drivers could be wrong because I had problemens with them before(With a GPU that was not seen by my OS), but I have built SFML from the sources with MinGW , could It generate some problems ? And I am on a Laptop with the Graphical part of a CPU and a Radeon HD 7600M with up to date drivers. I am going to try deactivating one or the other.

Ok know I am trying to figure out if the the texture is correctly put on a Sprite , but I can't figure out how to checks it , anyone has an idea how could I do it ?

The loading seems to be fine because this :

    if(!lavaFlow.loadFromFile("lavaFlow.png")){
        cout<<"Error"<<endl;
    }

doesn't print anything , but is the loading of a picture wich is 260*260 long take some time , or is it like 0.1 sec ?

EDIT : Nevermind ,even if the loading time was a bit long , It would not be over 23 minutes .....

Is there anything for checking that the texture is loaded ? Not going throught a sprite , just cheking if there is a texture like with checking a size that is the size of the file you defined it with (in pixel) or if a pixel RGB is equal to the one on the original picture , because my code is nearrly the minimal , + texture&sprite defined + clean/draw/display

Ok so looking at my code I understood the problem of it (for the event loop) , yeah my thing was in the wrong loop because it was being refreshed only on events so I bumped it little down , in the while window.isOpen() loop , but I still have a big black screen ........

Looking at the tutorials I saw the one on drawing shapes , so should I draw A ssquare and apply a texture to it instead ?

EDIT: Nevermind RectangleShape has the same problem, could it be the texture not loading properly ?

I am coding a game , and just started some of the graphical part so I just started to try using SFML for it , but I had a bug where a sprite would not show on screen, so I tought that ther was bugs deep into my code , and so I made a fresh project with what could be considered like the most basic code to show a Sprite , but it is doing the same thing , and I can't understand why...

     Here is the basic code(even if you could guess it x) ):

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

using namespace std;
using namespace sf;

int main(){
    RenderWindow window(VideoMode(500,500),"Test");

    Texture lavaFlow;
    lavaFlow.loadFromFile("lavaFlow.png");

    Sprite lavaFlowSprite;
    lavaFlowSprite.setTexture(lavaFlow);

    while(window.isOpen()){
        Event event;

        while(window.pollEvent(event)){
            if(event.type == Event::Closed){
                window.close();
            }
            window.clear();

            window.draw(lavaFlowSprite);

            window.display();
        }
    }
    return 0;
}

And few things to know , since I am compiling on Debug , some of the error shows , so I know that the Image has been loaded , and the image was firts in jpeg so I thank that it was maybe a type problem , so I converted it into png

Thanks to anyone who could help me !
