40d:Floodgate
Revision as of 17:19, 4 November 2007 by Zaratustra (talk | contribs)
Floodgates are objects that regulate the flow of fluids. A wood, stone or metal floodgate will suffice for water flow, but only steel will hold back magma. Floodgates can be linked up to levers or pressure plates to create farms, a water source or as a defense against invaders. An open floodgate can be walked through, a closed one can not.
Steel floodgates are essentially "one-use only" because the magma will melt the stone mechanism, thus breaking the open/close trigger.
If there is no roof above your floodgate and there is a water source from a higher elevation, the water might spill over it.
In the new version, floodgates are almost like doors with the 'Forbidden' option set at all times.
