Ruby sleep or delay less than a second?

I'm making a script with ruby that must render frames开发者_Python百科 at 24 frames per second, but I need to wait 1/24th of a second between sending the commands. What is the best way to sleep for less than a second?

sleep(1.0/24.0)

As to your follow up question if that's the best way: No, you could get not-so-smooth framerates because the rendering of each frame might not take the same amount of time.

You could try one of these solutions:

• Use a timer which fires 24 times a second with the drawing code.
• Create as many frames as possible, create the motion based on the time passed, not per frame.

Pass a float to sleep, like:

sleep 0.1
