Fan (Mechanic)

The Fan was a gameplay mechanic in F-Stop. It was a capturable prop that would push other props and the player around in whatever direction it was facing. For example, you could place the fan on the floor, and if you were to place a box on the fan, it would start floating up. It works similarily to (and may have been the inspiration for) the excursion funnel in Portal 2.

It has several maps dedicated to it in the vmf leak and is mentioned in several F-Stop reslists.

The real code that was used for the fan was shown off in LunchHouse's Exposure series. It works the same way as the point_push entity except it has a model.
