Is there a way to get the wind direction and the direction of the particles in a particle system to randomly change directions during a game?

the wind automatically does this unless you set "maximum adjustment per tick" to 0 and/or the "time between adjustments" something ludicrously large.

I get it now. Before I could only get the wind to go one direction, but then I realized it was because I had to enter negative values in the I, J, and K components to get them to go the opposite direction.

Thanks.
