How do I make random movements.

What is the best way to go about if i want to make random movements. Kind of like an insect (fireflies) moving around or a particle froating around in a bit turbulent air? I need a bit or randomised speed and direction but kind of smooth. no steep angle changes in direction.

Would something like sine work?

Something like this?

Random fly-movement

It's just these events:

If you want it less drastic, you could always just set an instance variable instead of changing the angle directly and rotate 1 degrees towards it if the current angle is not between -1 and +1 of the new angle..

Thanks. Maybe some anglelerp here would help smooth out the direction changes. I don't really want any sharp changes in direction, more softer curves. Will try it out when i get back home.
