Hi, i wanted to render a Tiled map, each tile 12*12px.
My first way was to draw every single tile itself. But i think this may cause too many drawcalls,
any better ways?

Group a few tiles into a single image. Then cull the images off-screen, and you draw all the screen with very few tiles : )

How does sf::RenderImage work exactly?
Or to keep things simple... if i do something like

Code: [Select]


for( y = 0; y<height; y++)
{
    for(x = 0; x <width; x++)
    { 
         renderImage.Draw( tile[y][x].sprite);
     }
}

... render to window ...

will this be more effective than rendering directly to screen?[/code]

If you render all your tiles to your RenderImage once and then use that Image every frame, yes, it will be more efficent than rendering every tile every frame. If you render all your tiles to the RenderImage every frame though, it will not be any faster.
