i was wondering if there was a way to have particles that are invisible but have a physics collider similar to water, to be generated in a large world environment without lots of problems.
GameObject>CreateOther>WindZone should do what you want.
I haven’t messed around with it at all, though.
I would just create a public Vector3 called windSpeed. Then for all of your moveable objects do:
gameObject.rigidbody.AddForce (windSpeed);
a Vector 3 is just an x,y,z coordinate. so if you had:
public Vector3 windSpeed = new Vector3(1,0,0);
Your wind would be moving 1 unit in the x direction.
