... my ideea is similar but different.

Ideea is that after a x value of pollution we create, the enemies to did another evolutions unlock a new tech: tunnels. They are "invisible" but still gather underground, and of course, we can't see or attack them (different from rampant's, and also another ...

... did not work, sorry :D

In the screenshot above, I was trying to angry ghost a rocket turret, but the smart belt system decided it should go under instead, when I was expecting it to just delete the normal belts and not try to tunnel under the turret.

Hi, I found an error when under ground transport belt causing an issue during load game.
Issue is reproducible on sandbox, when I build new tunnel, delete one end, and change direction and force rewrite existing end (SHIFT+CONTROL) and create new second end. If I save the game, I can't load it anymore ...

... Thank you so much for considering this!

By the way, I’ve noticed something regarding the deactivated “smart mode.” In some cases, tunnels are still being created automatically when placing blueprints—for example, conveyors are sometimes turned into tunnels. This might not be intended ...

When you pick up a tunnel entrance with pipette button (Q), it keeps the orientation of the original, as expected
When you pick up a tunnel exit with the pipette button, it will reverse the orientation (turning it into a tunnel entrance).

This means that if you move a tunnel exit of an existing ...

... But by late game nothing is dangerous anymore anyway.

The vehicle would have no way to attack. It will only be able to drive or burrow itself and tunnel around underground. Exactly liKe the one from C&C. If the area is unexplored (the black fog of war thing) and you are underground as you drive ...

... seems to be an issue with the overhead train (signals). If I move the signals on the bridge down 2 squares it works fine since now it divides the 'tunnel' in two separate segments (visually, on the blueprint this looks odd). The two 'tunnel' tracks will also have different segment colors if placed in ...

... Do not do this on untrusted networks, and always implement appropriate firewall restrictions.

Alternatively, as I did, establish an SSH tunnel from the remote machine to the local machine that accomplishes the same.



On the remote machine:

... aligned. If the funnel is not on a chunk border, they move into it no problem. But if it has a wall on a chunk border, they do not care and just tunnel right through.

For demonstration, I have the following setup, in a brand new entirely-vanilla sandbox game, playing from the editor:

We played through redmin, then tried through hamachi, nothing helps.
I thought about opening a personal tunnel between computers.
But I think that the problem is not in the connection between me and the friend, but in the fact that my computer is not able to ...

... around, not much more than that, so if this idea is impossible please forgive me.

It seems to me like it should be possible to make train tunnels work like this:
--Place a tunnel on the map the same way you build underground belts/pipes.
--The tunnel tracks are still on the same game surface ...

Digger Biter/Spitter - (Attacks as normal once surfaced, Think of a sand mole, doesn't really leave a traversable tunnel in it's wake)

Drag placing is a really cool feature!

But it needs some polishing.

1) Rotate-while-drag doesn't have any visual cues for current direction.
2) It builds unfunctional mess in some situations. I.e. place two pipes with one tile between them and try to build a belt over them. Belt correctly jumps ...

... Moleholes should be destroyable individually as well, but that does not stop the biters.) - Additionally.. these could allow other biters to tunnel into the player base? (if walled in)

Why ?
More biters, more strategy, more options, more survival sense needed. It adds to the vanilla game ...

... way - for example a teleport by an entity overseeing that piece of rail.

Why ?
There is already mod (although looks abbandoned) called Train Tunnels which works on basis of additional ("underground") game layer and "Tunel Entrances/Exits" (further called Interfaces) that teleport pieces of ...
