Minecraft Multiplayer: GWJ World

Most of my piston doors use a button on both sides, each connecting to the same time delay circuit. So what a time delay circuit does is take the brief redstone signal sent by a button press and make it last longer. There's two ways of doing this: basic and advanced.

The basic method is a set of redstone repeaters run in parallel set to different delay amounts. This is pretty straight-forward and simple to set up and understand. It's also more compact when using small delays.

The button signal comes in from the left, passes quickly through the first repeater, more slowly through the second pair, and slowest of all through the last 3. They're timed so that the output (top right) stays on the whole time. This circuit here will only stay on for about 3 seconds total.

The advanced method is to use a memory circuit, where the button turns the circuit "on" and also sends a signal through a long series of delayed repeaters to turn the circuit to "off".

So this would make a door stay open 3 seconds? Is that the reason a delay is needed?

I was hoping to use a lever outside and a prssure plate inside. (from a visual standpoint only)

A piston door using just a button or pressure plate runs the risk of crushing the person trying to pass through.

That's how my thing works, but with buttons. Whenever you press one of the buttons, it toggles the current on/off so that you can pass through the door at your leisure, instead of having it close on you and slowly suffocate you like Q's doors.

EDIT: this isn't the setup I have, but it's a simple and compact multi-input toggle for people just starting out with redstone. I would suggest leaving out the torch and replacing the dirt block with a redstone block to make it even more compact. You can use redstone dust to move the buttons wherever you want them, too.

I tend to build my setups as fire-and-forget doors. A door that stays open a few seconds after a button is pressed, then closes on its own.

Hmm Ill have to think about it. I don't know if I prefer automatically closing on a timer or not.

I was planning on closing an area 4 wide by 2 tall from the top and bottom kind of like a mouth. See below. I assume a piston goes from 1X1X1 to 1X1X2.

X=stone
P=piston
I=iron bars

Iron bars have the additional virtue of being a transparent block, and therefore shouldn't suffocate you if they close on you.

Yeah, but the iron bars will make the pistons visible, and if it's not a crazy super secret hidden ninja entrance than what's even the point of using pistons in the first place?

BECAUSE

Well how about 2 rows of iron for each part of the gate?

Could I walk across that? and will the piston move 2 blocks up and down?

The problem is pistons are only stuck to one block. They'll push lots of blocks, but are only going to pull the closest one back. That's why I used sand for my falling block gate.

Well shoot.

Here's a good example of what it takes to build a gate which does it:

You might be able to make it a bit more compact now that we have redstone blocks. Wouldn't it be nice if you could make faces of blocks stick to each other somehow?

When I build piston doors, they are either 2x2 that slide horizontally like a Star Trek door, or a gate 2 blocks high and 4 or more blocks wide, where the top half goes up, the bottom half goes down.

For example, here is the gate on my current castle project:

Activated by a button inside or outside, set up on a 3 second timer. The bars go up, the quartz descends. This one was novel because it's the first diagonal one I've built, but the fundamentals are the same.

Now for something more banal. I completed a horrific security system in Goodsprings (village around (-317, -183): fences with sand and cacti atop. The village is oddly situated on the border of two biomes, so while this looks okay in the desert part it doesn't quite fit in with the woods. I think it'll be okay, though. I'd be interested to hear suggestions, though.

Then I thought I'd hop on the rail to/from spawn, and noticed that there's no powered rail in my neighborhood. I recall a fairly recent discussion here about how far apart it's practical to place them, so perhaps I'm just in the doldrums, the hinterlands, the Ohio of this rail line. There are a few hills, especially one about 5-6 blocks high on the way to spawn.

What I'm saying is I wanna use the rail but am uncertain if I should make up some powered rail and adapt the local leg or if there's already a design to take care of that. I'll obviously have to create a small station anyway just for launch, but I'm not sure in which direction its intended to run.

I need to research redstone. Is there a more compact way to hide the redstone torch powering a rail than to place it directly under the block on which the rail is set?

Any news on when the server will update to 1.5.2?

I discovered today that you can't combine two different types of slabs in the same block space. I was hoping to make something that would look like a stone cap on a column, but this look works best if the cap rests a half block above the surrounding exterior, like a wainscot. For example, my plan was to have one block of stone brick, a stone brick slab on top of that to continue the pattern, and a stone slab on top of that to break it up and look like a cap. This way, the wood column above the stone cap wouldn't be floating over empty space and the cap would be above an adjoining stone wall.

Do any of you helpful folks know how to fake a stone cap on a column or create a similar look?

Edit: I meant to ask this in the main MC forum, but I'd love to hear from you guys too.

redstone blocks.

Oh, duh. I knew about 'em but it didn't even occur to me. Much obliged.

.

I put those rails there, but I have no sense of ownership over their improvement. As for powered rail every ~38 for occupied every 6 for unoccupied carts.

don't use a torch, use a redstone block. Unless you need to be able to turn it off for some reason.

Hinterlands? Are the Wildhammer dwarves giving you guff again? Because we can fix that.

Does that apply if I'm in Ohio? Because I could use some help escaping Ohio.

redstone blocks.

Or put a detector rail before & after the powered rail.

Found a bunch of loose diamonds by the anvil at the Enderman farm. Anyone forget to remove diamonds from their crafting area and drop them on the ground? If so, let me know.

So... uh... when's the server going to get the update to 1.5.2 that was released yesterday?

Erm, yeah, that was totally me.... not.

Whoops! Just found out the hard way that the client has to be the same version as the server!

Well sometimesdee, I also expect whoever claims the diamonds will know how many there were.

7! I broke down a block and used 2 on the anvil to repair my shovel.... guess I left the rest in my hand as I left the anvil/picked up the repaired shovel v_v
