Graphics / passing texture through function

« on: December 23, 2011, 01:10:31 am »

Alright, I switched from SDL to SFML a few days ago, compiled 2.0 libraries and am currently using that.

In my code I create a struct for a sprite and fill the information in with a given function.

Code: [Select]


uint cSpriteManager::CreateSprite(string File, float X, float Y, uint TotalFrames, uint TotalAnimations, uint FrameWidth, uint FrameHeight, Uint32 Delay, int Repeations)
{
     uint SpriteID = m_Sprites.size() + 1;
     sSprite NewSprite;

     NewSprite.nTexture = LoadTextureFile(File);
     NewSprite.Animation = CreateAnimation(TotalFrames, TotalAnimations, FrameWidth, FrameHeight, Delay, Repeations);
     NewSprite.X = X;
     NewSprite.Y = Y;
     m_Sprites[SpriteID] = NewSprite;

     return SpriteID;
}

Texture cSpriteManager::LoadTextureFile(string filename)
{
     Texture Temp;
     Temp.LoadFromFile(filename.c_str());

     if (!Temp.LoadFromFile(filename.c_str()))
     {
          cout << "cSpriteManager: Could Not Load File " << filename.c_str() << endl;
          exit(1);
     }

     Temp.SetSmooth(true);
     return Temp;
}

There is no problem with this, it returns the Temp texture and fills it into NewSprite.nTexture no problems, the problem is trying to access it. I define the container for all the sprites as:

Code: [Select]


private:
     map<uint, sSprite> m_Sprites;


 and I have a function that I call to return the texture to display, since it is private, which is:

Code: [Select]


Texture cSpriteManager::GetTexture(uint SpriteId)
{
     return m_Sprites[SpriteId].nTexture;
}


Once I have all my textures and information stored I run the following code:

Code: [Select]


Sprite.SetTexture(SpriteMan->GetTexture(SpriteId));


This just gives me a white shape where the sprite would display, but if I make the container public and call it with:

Code: [Select]


Sprite.SetTexture(SpriteMan->m_Sprites[SpriteId].nTexture);


It works just fine, I probably missed something very simple here, I was passing the Texture around when I first loaded it up, but it doesn't seem to be working now.  I just don't understand whats going on after tinkering for an hour or so. I would greatly appreciate any opinions on the matter.
