how to make wind

im wondering how you would go a bout making wind a being able to control it happens with a mouse click?

I do not really know what you want to do. Are you using particles? Physics? Something else?

I like using AddExplosionForce, as suggested by someone else. Add a series of them and you can get quite a wind effect.

Ok it is really simple all you have to do is go to game object and click Create other and at the bottom of the list it should say "Wind Zone’ click that and then there will be an blue arrow with a fan icon.
