Insert images after App.Display();
« on: January 01, 2012, 11:33:27 pm »
I don't know how to do :cry:

Code: [Select]
#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
using namespace sf;
#include <iostream>
using namespace std;

 int main()
 {


     Image Image4,Image3,Image2,Image;
     // Create the main window
     RenderWindow App(VideoMode(800, 600), "Pofro Game");

     if (!Image.LoadFromFile("1.jpeg"))
         return EXIT_FAILURE;
     Sprite nav1(Image);

    nav1.SetPosition(30,20);

     if (!Image2.LoadFromFile("3.jpeg"))
         return EXIT_FAILURE;
     Sprite sfondo(Image2);


     if (!Image3.LoadFromFile("2.jpeg"))
         return EXIT_FAILURE;
     Sprite nav2(Image3);

     nav2.SetPosition(730,20);

     if (!Image4.LoadFromFile("4.jpeg"))
         return EXIT_FAILURE;
     Sprite miss(Image4);


     Font Arial;
     if (!Arial.LoadFromFile("verdana.ttf"))
         return EXIT_FAILURE;
     String Text("Hello SFML", Arial, 50);

     Music Music;
     if (!Music.OpenFromFile("nice_music.ogg"))
         return EXIT_FAILURE;

         Music.SetLoop(true);

     Music.Play();

    while (App.IsOpened())
     {

         Event Eventi;
         while (App.GetEvent(Eventi))
         {

             if (Eventi.Type == Event::Closed)
                 App.Close();

             if ((Eventi.Type == Event::KeyPressed) && (Eventi.Key.Code == Key::Escape))
             App.Close();

             if ((Eventi.Type == Event::KeyPressed) && (Eventi.Key.Code == Key::Space))
             App.Draw(miss);
                            }



float tempo = App.GetFrameTime();

        // Move the sprite
        if ((App.GetInput().IsKeyDown(Key::Left)) && (nav1.GetPosition().x>=2)) nav1.Move(-200 * tempo, 0);
        if ((App.GetInput().IsKeyDown(Key::Right)) && (nav1.GetPosition().x<=745)) nav1.Move( 200 * tempo, 0);
        if ((App.GetInput().IsKeyDown(Key::Up)) && (nav1.GetPosition().y>=2))   nav1.Move(0, -200 * tempo);
        if ((App.GetInput().IsKeyDown(Key::Down)) && (nav1.GetPosition().y<=556)) nav1.Move(0,  200 * tempo);


         App.Clear();

         App.Draw(sfondo);

         App.Draw(nav1);

         App.Draw(nav2);

         App.Display();
     }

     return EXIT_SUCCESS;
 }


doesn't work :cry:

Please, explain yourself better. By the way, App.Clear(); should be right after the while. This way the "miss" sprite never gets displayed.

Code: [Select]
App.Clear();

App.Draw(sfondo);

App.Draw(nav1);

App.Draw(nav2);

App.Display();

App.Draw(miss);


It is possible?

No, why would you want to draw after everything has been displayed?

Of course not, because you'll clear the window after drawing the last sprite.

But why do you want to do that? It makes no sense.

I want to make sure that when I press a button an object appears on the screen, but I do not want the object to be present when I app: display ()

Is there a way?

It's hard to understand you, but as Tex killer said, you have to put App.Clear on the beggining of the loop, or right after App.Display. That's why you can't see 'miss' object when you press key.

App.Clear fill the whole screen with some color, so you won't see anything displayed before you called it.

Code: [Select]

bool show;

App.Clear();

if(sf::Keyboard::IsKeyPressed(sf::Keyboard::A))
{
    show = true;
}

if(show)
{
    App.Draw(sprite);
}

App.Display();



EDIT: If you want the object only to show up while the key is still down, get rid of the boolean and the second if statement then put "App.Draw(sprite);" in the first if statement.
