So..... Would it be possible to have a system for retractable bridges?
A special terrain, that would have a switch, near it, that allows a pawn to use the switch (Mabe affected by global work speed?) and need to be tagged on\off like a normal switch, but without eletricity.
When it's on, it puts X-tiles infront\near it. Work required to switch may be derived by the number of tiles.
Broken bridge? Instead of just disappearing, make a png texture of a broken symbol (similar to the broken component) and make it something that a constructor have to go there and fix it (Maybe using the same material).


The idea is to treat the Bridge and switch, more like a "Blueprint". You place the switch near a water area, and it gives you a tool to set up the bridge that will be controlled by that switch.


I don't know what kind of dark magic would be needed to make it, but seeing all the stuff the mods have beeing able to do lately, this may be able to be done?
(and would make it more cool to have moats :O
