How can you animate sprite in SFML

Question

Suppose I have 4 images and I want to use these 4 images to animate a character. These 4 images represent a character walking. I want the animation to repeat while I press a key to move, but to stop when I do not delete it. It doesn't have to be SFML if you don't know it, only the basic theory will really help me.

Thank.

You may need some simple state apparatus. When the key is unavailable (see sf :: Input IsKeyDown method ), enter the character in the "animated" state. When the key is not lowered, the character must be in a "not animated" state. Of course, you can always skip this “state” and just do what I mention below (depending on what you are doing).

, "" , "" ( . ). , , 4- , (currentIndex + 1) % ARRAY_SIZE. , , . "" , .

"4 " , sf:: Sprite SetSubRect, . 4 , , , sf:: Sprite SetImage .
