Graphics / Having a Sprite manager. Trying drawing from it causes access violation

« on: January 03, 2014, 01:41:48 pm »

https://bitbucket.org/makerimages/chtt3r

I draw in TextBox.cpp, it causes an access violation, the call stack looks like this

        sfml-graphics-d-2.dll!5492a253()        Unknown
        [Frames below may be incorrect and/or missing, no symbols loaded for sfml-graphics-d-2.dll]

        ntdll.dll!778fb3f5()    Unknown
        ntdll.dll!778fb3c8()    Unknown

 

After I get the violation, VS leads me to    this line:

 spriteCursor=*chat->getSpriteManager()->getSprite(0);

What may the cause be and how to fix?

Graphics / Re: Positioning button sides equally

« on: December 13, 2013, 10:19:12 pm »

heres a schematic Im tring to do:

E TTTTTTTT E
E TTT E

T- text
E-button side sprite

as you can see, the buttons are not witht he same size,so what I asked for was how to make them the same size, no matter what txt is in them?

Graphics / Positioning button sides equally

« on: December 13, 2013, 02:28:44 pm »

Hey, I have this that makes my buttons:

contentT=sf::Text(content,*game->getGuiFont());
        contentT.setColor(sf::Color::Black);
        contentT.setCharacterSize(18);
        contentT.setPosition(xPos-content.length()/(2*contentT.getCharacterSize()), yPos-2);
        sprLeft=*game->getSpriteManager()->getSprite(3);
        sprLeft.setPosition(xPos-57,yPos);
       
        //sprLeft.setPosition(xPos-(content.length()/2)*(contentT.getCharacterSize()/(content.length()/2)),yPos);
        sprRight=*game->getSpriteManager()->getSprite(4);
        //sprRight.setPosition(xPos+(content.length()*content.length()*1.9),yPos);
        sprRight.setPosition(xPos+177,yPos);
 

what the matter here is, is that the sprLeft and sprRight are not aligned to equal positions on x when buttons are different in text lenght.

So for example

button with content "New Game" would be different sized than a button with content "Options", how could I make the buttons be equally sized/aligned no matter what the content lenght is?

General / sfml event handling for my buttons

« on: December 11, 2013, 08:46:14 pm »

Hey, I got a button class like this:

#include "Button.h"


Button::Button(std::string content,int x, int y,GameObject* gameO,GameWindow* wI): xPos(x), yPos(y),game(gameO), windowIn(wI)
{
        sprLeft=game->getSpriteManager()->getSprite(3);
        sprLeft->setPosition(xPos-content.length()/2,yPos);
        sprRight=game->getSpriteManager()->getSprite(4);
        sprRight->setPosition(xPos+(content.length()*content.length()*1.9),yPos);

        contentT=sf::Text(content,*game->getGuiFont());
        contentT.setColor(sf::Color::Black);
        contentT.setCharacterSize(18);
        contentT.setPosition(xPos-content.length()/2, yPos-2);
}


Button::~Button(void)
{
}
void Button::draw()
{
                windowIn->getWindow()->draw(*sprLeft);

        windowIn->getWindow()->draw(contentT);
                        windowIn->getWindow()->draw(*sprRight);

}
Button::Button(void)
{}
 

and it is made and drawin in a class like this:

#include "MainMenuWindow.h"


MainMenuWindow::MainMenuWindow(GameObject* gameO, sf::RenderWindow *rW)
{
        game=gameO;
        window=rW;
        newGameButton=Button("New Game",window->getSize().x/2-50,window->getSize().y/2-60,game,this);
}



MainMenuWindow::~MainMenuWindow(void)
{
}
void MainMenuWindow::draw(void)
{

        newGameButton.draw();
}

 

what I would like to do, is get mouse click coords in my Main.cpp event loop(standard one) and do something if newGameButton was clicked, how could I do so? Bare in mind that the  Button class is meant to create multiple buttons, all with different actions.

Graphics / [2.1] sf::Text wrap at a specific X co-ord

« on: December 11, 2013, 03:03:08 pm »

hey, lets say I have a text like this:

contentT=sf::Text(content,*game->getGuiFont());
        contentT.setColor(sf::Color::Black);
        contentT.setCharacterSize(16);
        contentT.setPosition(xPos-170, yPos-70);
 

and it has a long piece of text(like ddddddddddddddddiwwwwwwwwwwwwwwwwwwwwwwwwwwwaaaaa) in it, the xPos and yPos are relative to the current object these are in, the whole container width is 349px

How could I now make the contentT, when drawed- do a line wrap at lets say xPos+170 ? and go to the next line at xPos-170 again?

SFML wiki / Re: Animated Sprite class

« on: December 01, 2013, 12:37:23 pm »

using this for some experimenting, seems simple and easy enough to grab a hold of in a few minutes. What would be nice though, is to be able to set the frame to one fixed frame and then be able to for example only animate frames 2-6 and return pack to frame 1 when done, or something like that.

did so, found nothing I could easiliy implement...

EDIT: can I easliy convert a shared_ptr back tot he object it reffers to for sprite.setTexture()

Then you could use a shared_ptr

how?

I`m 99% sure you cant pass in a hard directory for the file path. move the test.png to your active workspace for Debug and remove the C:\ in the path

But I cant seTexture when I have the getTexture return a pointer for an example.

HAving the white square problem, but can figure out where the issue exactly is.

Can anyone figure out where exactly do I lose the texture and what to do to avoid it?
