I've been using ladders to get up and down, but water elevators seems like a cool way to get up and down. They work faster, and I don't need to keep pressing keys to get up or down..



But I have some flaws in my design.. First, I haven't found a way to not step on magma block. I tried to put magma block one block below exitpoint, but if I put in a trapdoor, fence post or anything like that, I disturb the water stream and it is no longer going fast downwards.. Is there a way to avoid hitting the magma block when at the bottom? Not like it's much damage to talk about, but would be nice to avoid.



Also, going down, I can get out at various points, though I have to be fast to get of at the right stop.. But going up I seem to go very fast and I'm not able to get off at an intermediate stop. If you want to stop at many levels, are water elevators still useful? Do you typically create elevators going only one level up at a time, so you need to switch elevator to go further up?


I prefer to use water elevators that are just waterflows with air columns on all four adjacent blocks (rook adjacent not queen adjacent so no diagonals).

This is slower but it allows you to breathe and increases your max swim speed especially before 1.13. No magma blocks required and no magma damage.



Otherwise, make layered elevators are you implied.


If you struggle to swim fast enough in 1.13+, you can have just 1-3 columns, so long as you lean into the air as you swim up. Prior to 1.13 you want all four columns because swimming worked differently then.


Thanks for the info...



For now I created elevator within 7x7 structure, with an elevator in each corner. One going downwards, as I manage to get of at speed anywhere there.. One express up and two alternating upwards to interesting levels.. Might redo with more experience..



I read about the water above landing trick, but playing in a hardcore world it seems dangerous, if for instance a game patch should alter how it works or I should manage to land on sign holding up water or something.. Anyhow, bubbling down is more than fast enough for me.. Bigger gaps when getting off the upward streams sounds like a good idea..


Have you looked in your elevator lately? They get a lot of wear and tear. Carts, hospital beds, luggage and people are in and out daily. Good thing you can outfit your elevator interiors with solutions that are built to withstand the constant abuse to make sure they stay looking good. Learn how elevator interiors were born to protect.


i'd imagine these elevators are a tad different than the land elevators to account for the movement of the ship. but just curious what they do to them. is there an amount of 'roll' that they wont tolerate and will shut off?


More often an elevator simply breaks down (yep, I've been stuck in one once - eventually an engineer's face appeared in the roof trap-hatch & he sorted it :)) and if a ship is low on electrical power due to a generator problem they'll shut off half the elevators or more.


too bad there's not a people limit. after muster, way more than the 20 people that were supposed to be on it, were on it to get to top deck. probably would have been able to lift your legs and not fall


There is a roll (actually list) limit for the elevators, but it depends on the manufacturer and model. I don't believe I've heard of a statutory requirement. What most commonly happens is that the guide bearings that keep the car centered wear a bit, and the car travels up and down slightly off center, and when this gets too great the car sensors miss the floor sensors and the elevator "loses its mind" and doesn't know where to stop, so it shuts down.


We had that happen several times on just one cruise. The odd thing was that the last people who pushed their way in didn't seem to feel that it was on them to push their way back out so the rest of us could move along. It went this way every time the elevator overloaded and wouldn't go. Very strange.


The airlines spotted the one pilot problem years ago. Are you telling me that if that guy has a heart attack during rough seas and the elevators break down someone is going to come round saying "Is there an elevator engineer on board" who happens to be on a cruise vacation?


Not at all. I'm saying that of the 3-5 electrical engineers onboard (plus the electronic engineer, the automation engineer, and the Chief Electrical Engineer), there is one whose assignment is to maintain the elevators. This does not mean that he is the only person onboard who can knows how the elevators work, or could troubleshoot or repair the elevators, and even most of the mechanical engineers onboard would have the electrical knowledge to fix it.


What I am saying is that elevator maintenance is a full time job. That's all this one engineer does, keep up with required planned maintenance. Just like the rest of the electrical engineers are assigned to maintain specific equipment around the ship (one for galley and laundry equipment, one for engine room equipment, etc). The mechanical engineers also have specific equipment assignments for their primary maintenance, but everyone can lend a hand at anything.


Taking this concept of specialized maintenance further, typically there is one Assistant Refrigeration Engineer whose full time job is sanitizing the ice makers. Does that mean no one else can fix an ice maker? No. That means that by the time he finishes sanitizing the last ice maker onboard (and completing all other scheduled maintenance and checking the units for proper operation), the schedule calls for him to start over at the first one again.


Marine engineers are the definition of the "Maytag repairman", in that they are required to understand, maintain, and repair everything onboard, from the diesel engines to the machine that cuts blocks of butter into the little pats you have with your dinner rolls.


It took us too long to realize that the best way to deal with ship elevators is avoid them....or at least avoid them most of the time. There are many healthy (able bodied) passengers who use elevators all the time...even if they are going down one deck or up a deck. Sometimes these folks will wait 10 min for an elevator just to go down 1 or 2 decks. We used to also be guilty of elevator overuse. About 5 years ago, DW and I got into a crowded elevator with 2 passengers who coughed and sneezed as we moved up a few floors. About 2 days later we were also coughing and sneezing, and it occurred to use that an elevator is an easy place to pick-up some nasty critters. So we started to avoid elevators whenever possible. This is good for our personal conditioning, helps burn off a few calories, avoids waiting around for elevators, and helps those who really need to use elevators. Now we generally will walk down 5 or 6 decks and routinely walk up at least 4. The payoff is that in the past 2 years we have cruised more then 200 days.....and never caught even a sniffle. Coincidence? Perhaps. of perhaps not :).


I agree, that elevators are best left to others if possible. I try and use the stairs often, even for numerous (10) levels, however, my wife cannot do more than a few floors and even then it is preferred to be going down.


I credit elevator avoidance for my losing a few pounds on our last cruise. Those who can't take the stairs up six decks should set themselves a different goal. Take the stairs up one deck and down two or take the stairs up three decks and down four, whatever works for you.


Although there is no right answer, one should follow the SOLID principles to make the design. SOLID principles are a set ofgolden rules used by object-oriented developers. SOLID principles consist of (reference to educative.io):


As shown above, I have giving one example run of my code. In the example, there are two people inside of the elevator thatwant to go to floor 5 and 3. A person outside the elevator at floor 4 wants to go to floor 0. And two people inside ofthe elevator want to go to floor 1 and 2.
