Question

Okay, so I have this code which just iterates through my object array blitting what needs to be blitted:

void Render()
{
    for(int Index = 0; Index < MAX_OBJECT_INSTANCES; Index++)
    {
        if(Game::ObjectArray[Index].IsActive() == false){}
        else
        {
            if(Game::ObjectArray[Index].IsHidden() == false)
            {
                SDL_BlitSurface(Game::ObjectArray[Index].CurrentSprite, NULL, Buffer::Screen, &Game::ObjectArray[Index].Position);
            }
        }
    }
}

I had a look in the call stack and I found this:

0x681247d8  SDL_UpperBlit

I have no idea how to fix this. I should also note I am using SDL mixer and SDL image.

Answer 1

1. Run the code in a debugger.
2. Step into the SDL_BlitSurface() call.
3. Verify that the arguments are looking correct.
4. Keep stepping, to see what causes the segmentation fault.

I would suspect that one or more of the arguments is wrong/invalid.
