PROS:
- Make your roofs block rain at last (the leakiest ceilings and dampest caves in history are no more; stay dry in a downpour)
- Make rain actually make drippy drops on all levels over the top of exterior / terrain builds
CONS:
- Needs zones or zone bricks to block the precipitation. Zones created with events work.
- Since the droplets actually continue for a tiny bit past the splash, a thickness of about 3 or 4 bricks is needed to be completely rid of all traces of rain inside. For example, if your roof is a 64x baseplate, it needs the event
onActivate > Self > setZone > Up [4] [0 0 0]
which, if it is not thickened, causes a layer of droplets a few bricks above the roof.
Great for caves, not so much for umbrellas and small porches.
For the tops of exteriors, replace 4 with 0, and attempt to make sure any interiors underneath it are a few bricks below the top.
