Need a air lock door

[Blacklotas]

There should be a door allow minions go through but stop air between two sides. I know there are mods for air lock doors, but I really like it to be built in the game.

The mod really did feel like it belongs.

It's not even the best option,  just a compact one.

shouldn't be compact (at least 4x3), shouldn't be cheap, should be an endgame option to speed up progress instead of forcing ppl to manually crease an airlock. passing speed could be upgradable, or maybe not, default slow or default fast.

the animation of a dupe going through it might include a dupe going through a playground rope crawlspace, or maybe them holding their breath, or some sort of massive ventilators.

There is one, it's called the Transit Tube

隔热门，需要单独研究制作，会显示2排制造材料，下面那一排选择没用，拆了后会掉落2个材料，就是制造的时候要用两种材料去制造

阻止气体交换，mod实测有效，气动门不会阻挡气体，机械门和电动门会阻挡气体流动，隔绝气体流动是工作正常的
