I’m writing a simple 2d tilemap engine using C++ and SDL2.

Question:

I have a tile class that contains the data of a tile:

class cTile { private:     // It basically says you should take a 32x32 part on sprite sheet     // starting from (spriteSheetX, spriteSheetY),     // and draw on screen at (positionX, positionY)     int positionX;     int positionY;     int spriteSheetX;     int spriteSheetY; } 

and a cGraphics class that stores the sprite sheets and draw things on screen:

class cGraphics { public:     void draw(int positionX, int positionY, int spriteSheetX, int spriteSheetY); } 

Now that these two classes don’t know each other, but I want to call draw() to draw the tiles. What are some good approaches to do that?

My thoughts:

• friend
• pass cGraphics to cTile objects and create a drawTile() in cTile that simply calls draw() in cGraphics
• create a top class say cGame that knows both and call draw() from there (so basically cGame draws, plays sound, saves/loads, etc.)

Now that for games at this scale, probably all will suffice. I’m wondering what’s your thoughts? Note that cGraphics is just one example. I can also have a cFile that does save/load and serialization/de-serialization, a cSound that plays some sound, etc.
