OK, I have an object that needs to rotate once every 20-30 seconds, and basically NEVER stop at that rate, meaning an infinate loop. Now, I could just keyframe it for frames 1-1000000000 or somesuch, but that would take AGES, so is there any way I can rotate it ONCE, and have it re-peat those steps? THANKS!
You need the animation for the game engine?
For a movie, normally you “cut” the scenes, so you don’t need a much longer
animation.
For the game engine you can add a timer sensor that fires the animation after an amount of time.
Anyway to make “infinite loops” cyclic animations press the little yellow arrow
icon that points up

Go to the IPO window after you have set the keyframes for 1 rotation. At the bottom on the right there should be 4 buttons which allow you to control how the ipo’s continues - including repeating your set keyframes linearly and exponentially! 
THANK YOU!!!
That is exactly what I needed ilac!
You’re welcome
