I'm trying to create a working portcullis for my castle, but I can't seem to figure out what I could be doing wrong. I've tried so many tutorials on youtube, but when the bottom half works, the top half does not, or when it does, each piston works separately and will repeat forever. I'm trying to make it so one lever can open and close the gate (on each side of the gate).
Does anyone know how to make this work in the Java Edition, 1.15.2? I'd be really grateful for any assistance, as I've been at this for nearly two days!
Can you provide some screenshots or maybe a way I could interact with your world? You may have just accidentally gotten some of the minor components wrong which can be easily fixed.
My original gate is on a server which I do not own, but I can replicate the problem on SP. How would I go about sharing my world with you when I'm done with it?
In your minecraft directory (possibly <your username>/AppData/Roaming/.minecraft) there should be a directory named "saves", inside that is a directory for each world.
Just upload the appropriate world directory somewhere and provide the link.
It might also be helpful to post the link to whatever tutorial you used for that version of your porticullis.
I see that somebody has commented on the video with the same problem in 1.15, unless that was you that would seem to imply that it doesn't work in 1.15
With complicated things like this it's usually safest to find on that was designed for the same version you are using.
No, that was not me. I wish I had seen it before I spent time making this.
Well, that is part of the problem. I did search up how to make a working portcullis on 1.15 but nothing seems to come up, so I was hoping someone here on the forums knew of one or could help me figure out how to fix it for 1.15.
Well, you could probably tear out everything underground and replace it with some other triple piston extenders that didn't break the gravel.
I tried messing with the timing to see if that would help but I just ended up with the pistons not going all the way back down.
The design is too complex and integrated to, at least for me, modify easily.
It's not easy to understand why the gravel breaks, I'm thinking there must be some bounce in the system so that the pistons go down and then bounce back up enough to break the gravel, or something like that.
Yes, the problem is definitely bounce, when the pistons retract they very briefly go back up again, maybe because the observers fire both when the repeaters turn on and when they go off again?
So the falling sand would hit the blocks going back up when they were in the halfway position and weren't counted as full blocks.
That is fantastical news! I'm going to go try it right now! Thank you so much Hexalobular! My castle will actually look 10000x better with this.
(And yea, whenever I activated my gate, for some reason it would switch random repeaters to different delays. I have no idea why, but that was the final straw for me, decided to get some help. )
EDIT
It works! The gravel doesn't retract until the fences push it down, but at this point I do not care! I have a working gate! Thank you so much Hexalobular!
They don't go down all the way until I press it again, and the fences come down to push them down. Let me look over my repeaters again, to be sure I copied your repeater pattern. And this is on singleplayer for now, but I want to build it on a server.
EDIT
My repeaters were exactly like yours; still happened. Not sure what could be the problem. I will rebuild it again.
Odd, I don't really know what I'm doing, I'm just messing around at random but for me it works with a total delay on the 2 repeaters to each set of pistons of 4-6, so all of the variants in this screenshot.

Have you heard of the high elves?
GAH!
URG!
ARGH!

Just testing.
Hello,
Okay, I built one of them and uploaded the world. And here is the video I followed (I have tried numerous tutorials after this one):
File: https://gofile.io/?c=nluTXk
It breaks the gravel and doesn't move the top portion when I press the button at the end. So now it looks like it is all screwed up, too.
I see that somebody has commented on the video with the same problem in 1.15, unless that was you that would seem to imply that it doesn't work in 1.15

I think I've fixed it!
I replaced the top row of observers with repeaters.
Well, almost anyway!It's working fine now except that you need to push the button twice to close it.(When I redid it from a fresh copy of the world it worked normally.)
Just tear out the upper row of observers, place blocks on top of the next row of observers and repeaters on top of them.
Btw, you had the wrong timing on the middle repeater for the column of pistons furthest from the buttons.
Also I think that had caused that column of pistons to get shoved down too far.
Just testing.

What?
You mean the gravel blocks the opening while the portcullis is open? That doesn't sound very useful!
Nothing like that happens for me.
The gravel does take a while to go all the way back down but it does go down by itself.
Is this on the server or in single player?
Just testing.
Did you leave the new repeaters with the movable torch in the first position like in my picture?
I can get the gravel to stay up if I move the torch to the fourth position but 1, 2 and 3 work.
You could try moving the torch on the original top repeaters to a lower position.
Lowering the position of the original without raising it on the new ones also makes the gravel stay up for me.
It's easy to test different settings, you can have a different setting for each pillar of pistons and see what works.
I haven't found any way to break it, I just change the settings back, push the button a few times and it goes back to normal.
Just testing.
