Graphics / calss not drawing a sprite properly

« on: December 21, 2010, 04:53:31 am »

Hi all,
I'm trying to write a class that manages a cursor but I'm getting some weird behaviour and I need some help to see if someone else can figure it out before it drives me insane.
class is defined as follows

Code: [Select]

class cursor
{
public:
int getCursorX();
int getCursorY();
bool isPressed();
cursor();
void update();
private:

sf::Sprite sprite;

};

cursor::cursor()
{

sf::Image cursor1;
cursor1.LoadFromFile("cursor.png");
sf::Sprite sprite(cursor1);
sprite.SetCenter(10.f,10.f);
myWindow.Draw(sprite);
myWindow.Display();
sf::Sleep(3);




}

int cursor::getCursorX()
{
return myWindow.GetInput().GetMouseX();
}

int cursor::getCursorY()
{
return myWindow.GetInput().GetMouseY();
}

bool cursor::isPressed()
{
return myWindow.GetInput().IsMouseButtonDown(sf::Mouse::Left);
}
void cursor::update()
{
int x=getCursorX();
int y=getCursorY();
sprite.SetPosition((float) (x-10),(float) (y-10));
myWindow.Draw(sprite);


}

In the constructor, I placed a line to draw and display the loaded sprite so that I could make sure that it loaded properly.
when I create a new cursor with the command

Code: [Select]

cursor *-cursorName- = new cursor();

the image is displayed in the top left corner of the window for 3 seconds as would be expected but then when I call

Code: [Select]

-cursorName->update();

it only draws a single white pixel at the mouse location, offest by 10 pixels, rather than my loaded cursor sprite. Ive even loaded a completely black image and the pixel stilll comes up as white.
