The GUI has two buttons on the lower right hand side of the screen, one closes all doors on the ship, and the other has two functions. If clicked once, the Open Doors Button opens all internal doors, if clicked again it opens the external doors flushing the ships oxygen into space. Is there some way to lock one or multiple doors, so that I can double-click the Open Doors Button and have every door on the ship open except the locked ones?

No it's not - if you require this level of control the best method to achieve it is to pause the game (space bar) and then manipulate the state of the doors manually.

If this is to vent atmosphere to space for every compartment except the ones your crew are in then the way that I would achieve this is to pause the game and open all doors by double clicking, and then close the doors that I didn't want open. As the game is paused while doing this opening the exterior doors will not vent the atmosphere from your ship until you unpause the game.

If this is being used as a method of killing boarders, then it's also probably not the best way of dealing with the situation. In these instances what I would do is just vent the individual compartments that the boarders are in so they have to break down doors to get to the next compartment so that you have at least one set of compartments between the boarders and your crew - in the event the boarders break into the compartments that your crew reside in while you're venting atmosphere, you will immediately vent the compartments that your crew are in as well with nowhere for them to escape to.

    This being at least the third question I've asked about doors in this game, you would think I'd start assuming the answer is no. Every clever idea I come up with to manipulate the darn things is met with failure. Who'da thought screen doors would be standard in spaceships?

  • yea, I upgrade doors to at least level 2 pretty early usually. But I was hoping to expand my bag of tricks.

    The pause button is very important in FTL - use it frequently!

    The only way to truly lock a door is to have a crystal crew member(hidden race) use his Lockdown ability in the room. This locks all the doors leading to the room as long as he has his ability up.

  • I generally vent the room the boarders are trying to break into through an alternate path before they actually get in - that helps to kill them more quickly.
