the minor is one of the first citizen, can you bridge the gaps and the big caverns
right now here is what he builds (not very pretty)

here is an example in fault:

another in the cave:

inconveniant:
1: can this kill by monsters (but it adds gameplay)
2: the bridge can burn through the lava and prevent it from continuing on this path so will work on another (bridge can be made of stone)

technical if possible in java minecraft (because I know that the java website)

before building
{if: (test 4 block after, an area of 5x5 = air)
{build the bridge;}
else: {normally builds minerX2Top or minerX2Right ect ...}}

example for test area (red glasse)

I'm sorry I'm french, I translate with google translate

@Raycoms who worked on the original miner Building logic?

I'd like to see the miner only fill the floors unless preventing flooding.

this is the first time I have a colony next to a fail
the nineur starts at a height according to his level, instead of the bridge it was a bend in dirt (as in the picture deeper)

for its that I thought about building a bridge for empty space.
@chriskeena the miner works remotely on the chematic before, so no problem
On the risk is the lava or the water that blocks the way, but he works on several tunelat the same time.
after if the air test area changes (ex: 5x5x2) to detect lava and water, he creates a tunnel

Edit: another possible bridge to solve the problem of water

I like this idea.

Build the bridge sections from cobble. The miner should be producing their own supply as needed. Cobble fences may require an outside source or teaching the miner the recipe.

Closed in favor of joint issue.
