Apply a force to the boxes in the direct of the wind (Possibly making it strong as it get's close to the source. Using maybe the line of sight object, test if the boxes can see the source, if not cut the amount of force WAY down.
EDIT: And certainly include an area of effect box if needed.
Its an idea too, i'm gonna try it certanly.. but any idea about if there are many boxes side by side it would be hard to move 'em all?
the idea is to make a strong ''base'' so they ill not move by the wind.. the function of the wind is to make the life of the player harder
