Can somebody tell me how one would approach making a tile engine.
I used to use sdl so im used to being to just blit a surface.
Is this possible in sfml if so how do you do it?

example code from sdl

Code: [Select]


for (int r = 0; r < rows; r++)
{
    for (int c = 0; c < columns; c++)
    {
          SDL_Rect rect = {c * tileWidth, r * tileHeight, tileWidth, tileHeight}
          
          switch(map[r][c])
          {
                case 0:
                     break;
                case 1:
                     SDL_BlitSurface(tileImage, NULL, screen, &rect);
                      break;
          }
    }

}

So pretty much is it possible to recreate something similar in sfml. Or if not what should I do?[/code]

with an image manager (there is one on my wiki), and a set of sprite (eg a std::vector).

Isn't there already one tile engine on the official wiki ?

There is this resource manager on the official Wiki. Also, in SFML 2.0 there is planned to be a batch-rendering mode that will improve the performace of tile maps.

After thinking about it for a while, you could use the sf::view class to scroll around a bunch of sf::sprite objects placed at absolute coordinates. That way you wouldn't have to calculate which tiles are visible and which tiles are not.

Batch rendering is the 2d equivalent to mesh rendering in 3d. It means that since the vertex between 4 tile images is shared between them, it will only calculate the vertex position once and apply it to all 4 tiles.
