So of course I rewrite it and it starts working fine.

Can you try this? When I try replacing the defines with const ints, the window refuses to display again.

Wow, I had to replace
sf::VideoMode(_WIDTH_*_ZOOM_, _HEIGHT_*_ZOOM_) with sf::VideoMode(_WIDTH_ * _ZOOM_, _HEIGHT_ * _ZOOM_)

No, I have 2 GTX260Ms in SLi.

And here's my current code:

Code: [Select]

#include <SFML/Window.hpp>
#include <SFML/System.hpp>
#include <SFML/Graphics.hpp>

#define _WIDTH_ 32
#define _HEIGHT_ 64
#define _ZOOM_ 20

int main()
{
    sf::RenderWindow App(sf::VideoMode(_WIDTH_*_ZOOM_, _HEIGHT_*_ZOOM_), "Test");
sf::View View(sf::FloatRect(0, 0, _WIDTH_, _HEIGHT_));
View.Zoom(_ZOOM_);
sf::Image Image(_WIDTH_, _HEIGHT_, sf::Color(0, 0, 0));
sf::Sprite Sprite;
sf::Uint8 *Display = new sf::Uint8[_WIDTH_ * _HEIGHT_ * 4];

while(App.IsOpened())
{
sf::Event e;
while(App.GetEvent(e))
{
if(e.Type == sf::Event::Closed)
App.Close();
}

for(int i = 0; i < _WIDTH_; i++)
for(int j = 0; j < _HEIGHT_; j++)
{
Display[(j+i*_WIDTH_)*4] = i*j % 255; // R
Display[(j+i*_WIDTH_)*4+1] = i*j % 255; // G
Display[(j+i*_WIDTH_)*4+2] = i*j % 255; // B
Display[(j+i*_WIDTH_)*4+3] = 255; // A
}

App.Clear();
Image.LoadFromPixels(_WIDTH_, _HEIGHT_, Display);
Sprite.SetImage(Image);
App.Draw(Sprite);
App.SetView(View);
App.Display();
}

delete [] Display;
    return 0;
}

Now I actually put my rendering code in the right place, but it's still not displaying.

FML. It's working now, but the window isn't showing. When I put my cursor over the icon on the taskbar, I can preview it, but it's not popping up/displaying.

I always had difficulties with pointers. I'm trying to duplicate the code here to draw pixels on the screen. I think the issue is with my pointer to Display.

Here's my code:

Code: [Select]

#include <SFML/Window.hpp>
#include <SFML/System.hpp>
#include <SFML/Graphics.hpp>

#define _WIDTH_ 32
#define _HEIGHT_ 64
#define _ZOOM_ 20

int main()
{
    sf::RenderWindow App(sf::VideoMode(_WIDTH_*_ZOOM_, _HEIGHT_*_ZOOM_), "Test");
sf::View View(sf::FloatRect(0, 0, _WIDTH_, _HEIGHT_));
View.Zoom(_ZOOM_);
sf::Image Image(_WIDTH_, _HEIGHT_, sf::Color(0, 0, 0));
sf::Sprite Sprite;
sf::Uint8 *Display = new sf::Uint8[_WIDTH_ + _HEIGHT_ * 4];

while(App.IsOpened())
{
sf::Event e;
while(App.GetEvent(e))
{
if(e.Type == sf::Event::Closed)
App.Close();

for(int i = 0; i < _WIDTH_; i++)
for(int j = 0; j < _HEIGHT_; j++)
{
Display[(j+i*_WIDTH_)*4] = i*j % 255; // R
Display[(j+i*_WIDTH_+1)*4] = i*j % 255; // G
Display[(j+i*_WIDTH_+2)*4] = i*j % 255; // B
Display[(j+i*_WIDTH_+3)*4] = 255; // A
}

App.Clear();
Image.LoadFromPixels(_WIDTH_, _HEIGHT_, Display);
Sprite.SetImage(Image);
App.Draw(Sprite);
App.SetView(View);
App.Display();
}
}

delete [] Display;
    return 0;
}

Window / Scaling a Window?

« on: June 23, 2011, 04:47:07 pm »

The intention is to keep the pixely look. I meant something like is there a setting that can scale the 64x32 resolution to whatever size the window is. I'm new to SFML so the only way I can think of is drawing boxes for each pixel.

I want to make a Chip-8 emulator. It has a 64x32 screen. What would be the best/easiest way to scale it up to a more sensible resolution?
