Floodgate Help
« on: June 06, 2011, 08:26:03 pm »
Are glass floodgates non-magma-safe? The wiki says they're ok for floodgates (but that small glass stuff melts), but when I opened one to let magma through, it disappeared, and I cant close it again. Unless the mechanisms have to be magma-safe too or something? I know they work fine when closed - fortunately, I had two glass floodgates in place, and the other one was closed, so I didnt flood my fort, but Im wondering what I did wrong.

I used green glass floodgates with marble or rhyolite mechanisms.

IIRC green glass things are only magma safe as long as there is no magma on the same tile as they are, otherwise they are destroyed.

According to that same article, glass floodgates are fine, but glass goods for some reason aren't.


EDIT: Neither marble or rhyolite are magma-safe, which would be the reason your floodgates failed.

Wrong; glass is entirely magma-safe. In theory, anyway, but floodgates are always magma-safe. I've heard that there are oddities where buildings made out of glass are magma-safe even if the items that make up the buildings would melt in magma, but in this case that isn't an issue.

The problem is that you used non-magma-safe mechanisms. All items that are part of the building itself - that is, items that are marked with a white [ B ] when you query the building with the t-cursor - need to be magma safe, or the building will deconstruct due to heat. Mechanisms are part of the building they are linked to, so that is why your stuff melted.

Actually, I've heard that all material is magma safe until the magma occupies the same tile.  A closed floodgate or door will hold back magma, even if it's made of lignite.  It's only when it's opened and it occupies the same tile that it catches fire.  I've never tested this, though.

Well, I know thats not true; I had a door in the room that I flooded, and it melted just fine.

And ok, I hadnt known the mechanisms needed to be magma safe too. Though apparently the other gate (which is closed) seems just fine, though it didnt have safe mechanisms either. Maybe it only matters when the gate is open, since when its closed it counts as a wall (which are always faux-magma-safe).
