Graphics / Key Pressed

« on: October 28, 2010, 07:10:40 pm »

Hi
Can some one tell me why pressing the up key and moving the cursor has the same effect in the following code:

Code: [Select]

#include <SFML/Graphics.hpp>


int main()
{
    srand((unsigned int)time(NULL));

int x, y;

// Create main window
    sf::RenderWindow App(sf::VideoMode(1200, 800), "SFML Graphics");

// Change color of background
App.Clear(sf::Color(128,128,128));
App.Display();



// Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
       

   if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Up));
   {
       x = rand() % 1000 + 50;
       y = rand() % 600 + 50;

        // Draw a shape
       App.Draw(sf::Shape::Circle(x, y, 50, sf::Color::Red));

        // Finally, display the on screen
       App.Display();

    }

}

    }

    return EXIT_SUCCESS;
}

Thanks
Warren

Graphics / Event

« on: October 28, 2010, 04:47:23 pm »

Which is proper to use in graphics:

If(App.GetInput().IsKeyDown(sf::Key::F1))

or  

if(Event.Type == sf::Event::KeyPressed):: && (Event.Key.Code == sf::Key::F1))

They both appear to function.

Thanks

Graphics / determine color

« on: October 16, 2010, 05:14:12 pm »

App.Draw(sf::Shape::Circle(x,y,radius,sf::Color(255,0,0)));
App.Display();

The above code will place a red circle on the screen.
Is there code that I can use to tell me the color the circle?
Thanks

Graphics / Problem with circles coordinates

« on: June 08, 2010, 03:29:56 pm »

Why does the following code place circles at only one value of X?
Thanks
Warren

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
    {
int x, y, radius = 20;
 
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(1400, 900, 32), "Warren Graphics");

// Clear screen
App.Clear(sf::Color(128, 128, 128));

    // Start game loop
    while (App.IsOpened())
        {
// Process events
        sf::Event Event;

        while (App.GetEvent(Event))
            {
for(x = 0; x < 1400; x = x + 25);
   {
for(y = 0; y < 900; y = y + 25)
        {
App.Draw(sf::Shape::Circle(x, y,radius,sf::Color(255,0,0)));

        // Display window contents on screen
    App.Display();

    // Close window : exit
    if (Event.Type == sf::Event::Closed)
App.Close();

    //Escape key exit
    if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
App.Close();
        }
    }
}
    }
    return EXIT_SUCCESS;
}

SFML projects / first project

« on: June 07, 2010, 09:41:27 pm »

This code compiles and executes as is.
However I wish to allow the user to select the color in the function.
Using either cin or scanf compiles but does not execute.
Help please?
Warren

Code: [Select]

#include <SFML/Graphics.hpp>
#include <iostream>
using namespace std;

void NameColor();
int rd, gr, bl;

int main()
{
int j, radius = 25;
 
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(1400, 900, 32), "Warren Graphics");

// Clear screen
App.Clear(sf::Color(128, 128, 128));

for(j = 1; j < 5; j++)
{
NameColor();

// Draw circle
App.Draw(sf::Shape::Circle(250,j*100+5,radius,sf::Color(rd,gr,bl)));

// Display window contents on screen
App.Display();

}

    // Start game loop
    while (App.IsOpened())
    {
// Process events
        sf::Event Event;

        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
App.Close();

//Escape key exit
if((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape))
App.Close();

        }
    }
    return EXIT_SUCCESS;
}

void NameColor()
{
int value;

// Get color from Random
value = sf::Randomizer::Random(1,6);

// Get color from key press
// scanf("%d",&value);
// cin >> value;

// Define color
if(value == 1)
{
rd = 0;
gr = 0;
bl = 255;
}
if(value == 2)
{
rd = 255;
gr = 0;
bl = 0;
}
    if(value == 3)
{
rd = 255;
gr = 255;
bl = 255;
}
    if(value == 4)
{
rd = 0;
gr = 255;
bl = 0;
}
if(value == 5)
{
rd = 255;
gr = 255;
bl = 0;
}
if(value == 6)
{
rd = 0;
gr = 0;
bl = 0;
}
}

SFML projects / graphic.hpp vs window.hpp

« on: June 04, 2010, 04:19:06 pm »

I wish to write some code in C++ where it draws 4 circles on the screen with the program defining the location and color of each.
Then I want to draw an additional four circles with the user defining the location and color of each.
Do I need to use graphic.hpp or window.hpp?
Thanks
Warren
