Random question. How hard would an underground base be to make? I dont exactly understand all the physics of water, I know sometimes it will just flow over an opening or a path and othertimes it will flood it like.. a really big flood. I always wanted to try an underground base though but Im unsure how Id honestly go about it in a vanilla world.
When water falls, it'll fall until it hits a block, then spreads out eight in all directions, on the same plane.
If there is a drop, it'll drop until it hits another block, then the same rules apply.
This is how Etho spread water across a good portion of the nether in the MC server. Melted iceblocks into water source blocks, high up in the ceiling. Every one block drop allowed the water to spread another 8 blocks. Linear returns 8:1.[DOUBLEPOST=1373527236][/DOUBLEPOST]Either dig down into the bottom of the ocean floor, or build a small room, fill it to remove the source blocks, unfill it, then you have something to work with.
It's better if you just build into the bottom, then hollow it out and build a glass roof from there.
You can even build the glass roof one block below the sea bottom, then just clear the sea bottom layer for the most time efficient/easiest way.
