Thanks for the quick reply. I'd already checked the example you linked (it is a walking animation for a goblin and a 'spineboy') and using that example I managed to replace the character in our game with the same goblin (it's going to be the goblin until we manage to solve the collision detection etc).
So my concrete question is: I have the goblin displayed in the SFML window. I'd like to move it, let's say I hold the Right arrow key then it moves right with X speed utill the key is not released. Same with left and jumping.
I just don't know hot to change it's position.
It was easy using sf::Sprite, but I think it's type is sf::Drawable now. (SkeletonDrawable wich is an extension of sf::Drawable)
