Aquatica is a build for the Sustainable City Project made by me (MCOres), BusniesMan, and 4557336fvc. It is a under water city.
How we made it:
-cleared ground to a flat size
-built the center area/ middle dome
-built the hydro energy source and oxygen generator domes
-built the entertainment domes/ arcade and nature area
-built the 3 residence towers
-built grocery and food source area
-built path ways to areas
-build the floor for all of the areas
-build the sea weed around
-flooded the area around Aquatica using barriers and water blocks
We also used the / clone command to speed up clearing the area and flooding the map. All the structures were built by hand. Command blocks are also used to remove potion effects that the vending machine would give and to create a visual effect in the oxygen generating room.
