Sprite Sheets in SFML

[StormWingDelta]

Been hunting the forums for this and I know it has been done but can't find it.  I know it is similar to what is done with tile mapping but not sure what to use for the sheet and selecting the part of the animation.

Ehh, creating a sprite sheet is extremely simple. Just use gimp, photoshop or any other image editor to create a large image with all your small sprite images on it. Then, when setting a texture on a sprite just give the appropriate rectangle where the image you want is found in your big texture.

Create a sprite sheet, i.e. collection of multiple sprites, in your favorite image editor.
Then use setTextureRect on an sf::Sprite to "select" the part you want display.

or SFML.Graphics.Sprite.SetTextureRect(...) in SFML.NET

lol I think I'm doing it the hard way.

    public class SFMLAnimatedTexture
    {
        private List<Texture> animationlist;
        private Image sheetimage;
        private int activepaslide, delay,framecount, columns, framewidth, frameheigth;
       

        public SFMLAnimatedTexture(ref Image sheet, int animationdelay, int numberofcolumns, int framew, int frameh)
        {
            sheetimage = sheet;
            delay = animationdelay;
            columns = numberofcolumns;
            framewidth = framew;
            frameheigth = frameh;

            framecount = 0;
            activepaslide = 0;

            BreakupSpriteSheet(ref sheetimage, framewidth, frameheigth, columns);
        }

        public Texture SelectAnimationSlide(int slide)
        {

            if (slide >= 0 && slide < animationlist.Count())
            {
                return animationlist[slide];
            }
            else
            {
                return null;
            }
        }
       
        public void UpdateAnimation(ref Texture usertexture, int animationdirection)
        {
            framecount++;
            if (framecount > delay)
            {
                framecount = 0;
                activepaslide += animationdirection;
                if(activepaslide < 0)
                {
                    activepaslide = animationlist.Count() - 1;
                }
                else if (activepaslide > animationlist.Count() - 1)
                {
                    activepaslide = 0;
                }
                usertexture = SelectAnimationSlide(activepaslide);
            }
           
        }

        private void BreakupSpriteSheet(ref Image sfmlimage, int slidewidth, int slideheigth, int cols)
        {
            for (int i = 0; i < cols; i++)
            {
                int xloc = (i % cols) * slidewidth,
                    yloc = (i / cols) * slideheigth;

                animationlist.Add(new Texture(sfmlimage, new IntRect(xloc, yloc, slidewidth, slideheigth)));
            }
        }

    }
 

  Went for breaking it up into a list but I guess it wouldn't hurt to have a few different ways of doing it.
