First off, thanks again for the great videos.
One question that has constantly entered my mind when watching your videos is: "How do you safely build these water channels without causing your miners to drown?" And in the magma video, you had started a small forging operation, but how did you crack into the magma pipe without flooding that room with magma? It's just something that I don't understand. Do you build some kind of doorway that can block the flow? And if so, when you crack that final wall open, does the dwarf die?
Thanks!
This is going to be in the next video (not today, maybe tommorow). Basicly what i do is first dig out the path but leave a 1 tile wall between the magma. Then i place fortifications right in front of that wall. If i want to be extra safe, i build floodgates in front of that fortification walls. Then i build some stairs up, go above the tiles that are holding the magmafrom the fortification, and channel those out.
With that, the magma can flow in, but has to go through the fortifications, that filters any nasty enemies out, then has to go through floodgates if i have any, and it goes where i want.
When the magma is in your channels, channel out 1 spaceso the magma forges will work, and your done, you have a working magma forge.
Oh, and do remember to close of the channeled tile that opened the path with a grate/floor. I had a fire imp climb in that way, luckily he didn't do much damage.
Anyway more on that in the next vid, probably tommorow.
EDIT: well things happened and "tommorow" is over, and tommorow is saturday. Next ep will be sunday or monday.
