Channel doesn't stop overflow
« on: November 08, 2006, 10:24:00 pm »
I'm not sure if this is a bug in the game, or a mistake in the wiki.

The wiki says that channels stop overflow.

The game seems to disagree:

Note the bottom, left of the channel.

The channel is fully constructed - it has been so for a long time.

Natural river floods dont seem to be stopped by channels, which IMO is a bug, as well as logic-defying.

a channel is just a trough in the ground. If a cave river is flooding, it's sending a lot of water your way and could easily fill up a small hole in the ground and wash over it, especially if the channel runs north to south and the river floods from east to west.......

Channels do not stop natural river overflows.  If they did you could run channels along side the river and prevent those pesky overflows from washing things away.

But channels do stop unnatural floods.  A shallow trough in the ground has the power to stop a flood in it's tracks, to the extent that the water reaches the ceiling on one side of the channel, and yet the other side is completely dry.  That's a pretty darn effective drain.    :D

That sounds like a bug, perhaps.

Let me see if I understand you correctly:

code:

             +
FLOOD->      _
             +

You're saying that the flood is hitting that and it's going past the channel despite the doors being shut?

Are the doors being opened by the flooding as well? If so, my guess is that alternate code is being invoked without sufficient redundancy, although I'm not sure I still wouldn't be entirely certain why that code would be invoked.


Alternately, is it an permanent flood that's taking place? I'm trying to remember, but I think permanent floods aren't blocked by channels.

Natural floods also dont make steam when they hit lava.
