Graphics / Error with calling sf::Sprite

« on: December 18, 2011, 09:38:53 pm »

So after changing my code to use the global sprites I'm now getting a weird error related to:

Code: [Select]


Title = new sf::Sprite(ITitle);
Errors:

Code: [Select]


no matching function for call to 'sf::Sprite::Sprite(sf::Image*&)


Its giving the exact same error for each sprite when that line is ran.

This is pretty new territory for me, so I'm sorry its taking me a while to understand =\ Thank you so much for the help though.

That makes a bit more sense, but if I have multiple unique sprites along with music, and fonts in my LoadMedia() function, how would I handle that?

I realize I should have put that into the first bit of code, but I thought it would be a standardized solution, not handling each one separately.

--Using your way would mean using "sf::Sprite* Title = LoadMenu();" multiple times for multiple objects. While I haven't tried it, I have a feeling that wouldn't work as intended.

For example:

Code: [Select]


int LoadMedia();
int Menu(sf::Sprite*, sf::Sprite*, sf::Sprite*, bool, sf::Music*);
int Game(sf::String*, sf::Music*, sf::Sprite*, sf::Sprite*, sf::Sprite*, sf::Sprite*);

int main() {

LoadMedia();
Menu(Title, Easy, Hard,  MouseLeftDown, MenuMusic);
Game(HealthText, GameMusic, playerSprite,  World1, World2, spacestationSprite);

}


Code: [Select]


int LoadMedia () {

//Picture Data --------------------------------------------------
    sf::Image ITitle;
    if(!ITitle.LoadFromFile("media/images/UI/title.png")) {return EXIT_FAILURE;}

    sf::Sprite Title(ITitle);
    Title.SetCenter(221,51.5);

    sf::Image difficultyImage;
    if(!difficultyImage.LoadFromFile("media/images/UI/difficulty.png")) {return EXIT_FAILURE;}

    sf::Sprite Easy(difficultyImage);               //Easy
    Easy.SetSubRect(sf::IntRect(0,0,200,50));
    Easy.SetCenter(100,25);

    sf::Sprite Hard(difficultyImage);               //Hard
    Hard.SetSubRect(sf::IntRect(0,100,200,150));
    Hard.SetCenter(100,25);

//Music Data -----------------------------------------------------------------

    sf::Music MenuMusic;
    if(!MenuMusic.OpenFromFile("media/music/The Son of Flynn.ogg")) {return EXIT_FAILURE;}

    sf::Music GameMusic;
    if(!GameMusic.OpenFromFile("media/music/Separate Ways.ogg")) {return EXIT_FAILURE;}

// Text Data -----------------------------------------------------------------

    sf::Font MyFont;
    if (!MyFont.LoadFromFile("media/Bedizen.ttf", 25)) {return EXIT_FAILURE;}

    sf::String HealthText;
    HealthText.SetFont(MyFont);
    HealthText.SetColor(sf::Color::Black);
    HealthText.SetSize(20);
}


Code: [Select]


int Menu (sf::Sprite* Title, sf::Sprite* Easy, sf::Sprite* Hard, bool MouseLeftDown, sf::Music* MenuMusic) {

    (*MenuMusic).Play();

    (*Title).SetPosition(Menu.GetWidth()/2,100);
    (*Easy).SetPosition(Menu.GetWidth()/2,340);
    (*Hard).SetPosition... yadda yadda yadda

    Menu.Draw(*Title);
    Menu.Draw(*Easy);
    Menu.Draw(*Hard);
}

Anata
Unfortunately, that didn't work. Thanks for the input though.

Tex Killer
I'm not entirely sure how to do that, do you know of any good tutorials or are you willing to give an example?

Thanks guys!

Thanks!
Unfortunately after trying both methods, I'm now receiving:

Code: [Select]


error: Title was not declared in this scope


referring to where I call the Menu(Title) function in my main.

Hey Guys,
So I'm in the process of trying to optimize my game/project a bit-- trying to split things up from one giant, cluttered main loop to a main loop with a LoadMedia() function which defines my Sprites, Music, Fonts, etc. A Menu() function which runs the game menu loop, and the Game() function that runs the main game loop.

I'm passing the Sprites defined in the LoadMedia function to the Menu functions; however, I'm encountering some errors.

Any help would be greatly appreciated.

Code: [Select]


int LoadMedia();
int Menu(sf::Sprite*);
int Game();

int LoadMedia() {
    sf::Image ITitle;
    if(!ITitle.LoadFromFile("media/images/UI/title.png")) {return EXIT_FAILURE;}

    sf::Sprite Title(ITitle);
    Title.SetCenter(221,51.5);
}

int Menu (sf::Sprite* Title) {
    Title.SetPosition(Menu.GetWidth()/2,100);
}

int Game() {
//The usual stuff
}

int main() {
  LoadMedia();
  Menu(Title);
  Game();

  return EXIT_SUCCESS;
}


The errors I am getting are related to any sprite functions that I call in the Menu class. The one specifically related to the .SetPosition function is here:

Code: [Select]


error: request for member 'SetPosition' in 'Title', which is of non-class type 'sf::Sprite*'


Thanks in advance for any and all help!

Graphics / sf::View, sf::Style related Screen-Warp

Awesome, that works great!

Now the only question is, if I want this to work across different computer resolutions, is there a way to manually access the GetDesktopMode X and Y?

Graphics / sf::View, sf::Style related Screen-Warp

« on: December 06, 2011, 07:38:59 pm »

In working on my Asteroids project, I began using sf::Views and sf::Style::Fullscreen.

My monitor's native resolution is 1366 x 768 (16:9), so I was typically using sf::Style::Fullscreen to have the game run fullscreen and this all worked fine; however, as soon as I started using Views it began warping the game.

Ie. all of the planets became egg-shaped (The entire game was stretched across the X axis to fill the monitor)
 
I'm curious how to fix this, either changing the definition of sf::View or changing how the RenderWindow is initialized... Any help would be greatly appreciated.

Here is the related code:

Code: [Select]


//In main.cpp
{
sf::Vector2f Center(5000, 5000);
sf::Vector2f HalfSize(512, 384);
sf::View View(Center, HalfSize);

    sf::RenderWindow App;
    App.Create(sf::VideoMode::GetDesktopMode(0), "Onyx [Alpha]", sf::Style::Fullscreen);
    {
    App.SetView(View);

    if (App.GetInput().IsKeyDown(sf::Key::Add))      View.Zoom(1.1f);
    if (App.GetInput().IsKeyDown(sf::Key::Subtract)) View.Zoom(0.9f);

    View.SetCenter(pl.RenderPlayerX, pl.RenderPlayerY);

        App.SetView(App.GetDefaultView());   //Sets View to be correct for drawing the HUD

        App.Draw(SHealth);
        App.Draw(STempTop);
        App.Draw(HealthText);
        App.Draw(EnergyText);      //Draws the HUD
        App.Draw(FuelText);
        App.Draw(CurrencyText);

    App.SetView(View);
    App.Display();
    }
return EXIT_SUCCESS;
}


Here is a picture of the warped game:

General / Vector2f Help

« on: November 25, 2011, 06:12:55 am »

Hello Everyone,
I'm in the process of learning c++ and SFML and I've been working on a game in my spare time.
I've recently starting converting everything to using sf::Views and sf::Vector2f's but I've run into two problems I can't seem to figure out:


1.) I can't access the X or Y individually from a Vector2f's (to use in trigonometric calculations) and I'm curious how exactly to do this. I've tried treating it like a normal vector; however, I only receive errors.

2.) In addition, can anyone give advice on making a Vector of Vector2f's?
For example I have 100 Asteroids that each need their own Vector2f. Any examples or links to examples would be unbelievably beneficial as I'm having a hard time finding a relevant article.

Thanks in advance!
