Graphics / [SOLVED] Black window after clear/draw/display - draw called from an object.

« on: May 16, 2013, 12:33:17 pm »

Here's a small mock up/example of what I have:

class MainObject
{
private:
        sf::RenderWindow window;
       
        Map map;
public:
        //Constructor/destructor
        void Draw()
        {
                window.clear();
                map.Draw(&window);
                window.display();
        };
}

class Map:
{
private:
        sf::Texture texture;

        std::vector<sf::Sprite*> spv;

        sf::Sprite testsp; //Test case.
public:
        //Constructor and destructor that load a texture and setup sprites - These work! Really, they do!
        void Draw(sf::RenderWindow* window);
        {
                for (std::vector<int>::size_type tile = 0; tile != mapTiles.size(); ++tile)
                {
                                window->draw(*spv[tile]);
                }

                window->draw(testsp); //I thought I made a mistake in the vector or iteration but even this fails.
        };
}

This makes sense, right? I'm trying to draw a sprite (more accurately, a set of sprites) on the RenderWindow passed by reference from inside a child object. My problem is that nothing gets drawn on the screen.

Formerly, MainObject itself held the texture and sprite:

class MainObject
{
private:
        sf::RenderWindow window;
        sf::Texture texture;
        sf::Sprite sprite;

public:
        //Constructor/destructor
        void Draw()
        {
                window.clear();
                window.draw(sprite);
                window.display();
        };
}
 

This worked.



Clear() works because I can change the color the window refreshes to. I tried moving the whole clear/draw/display cycle inside of Map but had no success.

I realize this might be very little to work on. Shall I post a more in-depth description with parts from my actual code?
