This question already has an answer here: hello again I have a basic platformer game and I want to make an fps counter and cap the fps to 30 but I don't know how. I want this because when I start up the game sometimes the character moves realy fast and other times very slow. |

You should probably use framerate-independent movement, because then you wouldn't have to care about the FPS. What you are probably doing right now is in every frame you say However, what you should probably do is have Now, no matter what the framerate is, your character will move the same distance in the same amount of time. |

I believe what you want to add is a fixed timestep. If you wish to make your game's logic independent of your framerate, you'll want to look into adding a delta - a timestep that calculates the time between update calls.
