Sep 3, 2011I don't know anything for certain, but I'd assume it's just a glitch with redstone wiring and being on a multiplayer server... Did you check which sections of wire are or are not working when it stops? That could tell you when/where the problem is.Posted in: Redstone Discussion and Mechanisms
Sep 3, 2011I came back to minecraft after a several month and several patch hiatus, so pistons were new to me. I saw some videos and things about "piston elevators" and was disappointed to find they're simply a stack of pistons that shoot you up quickly, rather than something more stylized like... an elevator car. Unfortunately, I couldn't figure out a way to have a good looking elevator car that rises as a whole, but I did manage to make a 3x3 elevator platform that, with some work, could be connected to more copies of itself and eventually be a fully functioning (if slow) elevator. Not so great for moving around fast, but definitely a nice touch for large structures or an artsy feel.Posted in: Redstone Discussion and Mechanisms
Edit: Video up:
I'm uploading a video to Youtube that explains and shows it in full, but I'll try to describe the general principles here:
The elevator platform itself is made from sand, so that, ideally, it could slowly be lowered, too. Having it made of sand also allows for a large column of 3x3 sand to be inserted 1 layer at a time under the elevator to rise it up, as I'll explain.
At the bottom of the elevator is a 3x3 set of pistons facing upwards, which all fire simultaneously (except maybe the middle, depending on how you wire it). On top of these pistons is a few layers of sand; really, you only need one, but having several layers makes it easier to work with in terms of wiring and space. The pistons will lift this column of sand up a block, and one of the lowest layers will be pushed aside and replaced by a 3x3 area of dirt. Then, the pistons will lower- leaving an empty space between the dirt and the sand that's still on the piston (or the pistons themselves if you used just one layer). Into that empty space, a 3x3 area of sand is inserted using a system of sticky and regular pistons. Then, the sand that was shoved away by the dirt is reinserted, pushing the dirt back out, and the elevator is now one story higher than it was and is in its original state- a solid column of sand.
Here's the details on how it works, step by step:
Mechanism 1: A set of 3x3 pistons face upwards, with one or more (3x3) layers of sand on it. The pistons are fired simultaneously (or almost simultaneously depending on how you wired the center piston) and raise the sand column up by 1 level. One memory unit is used to keep the pistons raised.
Mechanism 2a: While the pistons are raised, you use a 3x3 area of regular pistons facing the sand column to push a 3x3 area of dirt. If Mechanism 2b has already been fired, the 3x3 area of sand will not only be replaced by the dirt, but will also push the pistons in 2b back to their starting position.
Check: Now, you have a column of sand resting on an area of dirt, keeping it from falling. Mechanism 1 then retracts to its off position, leaving a space between the sand it's supporting and the newly placed dirt. I did this using repeaters for time counting, but you could also wire the end of Mechanism 2a's wiring (firing the 3rd normal piston) to set mechanism 1 to off.
Mechanism 3: Using a series of sticky pistons and regular pistons, a 3x3 area of sand is inserted into the gap. To do this, there are 2 rows of sticky pistons facing the column, and at the end of them, a 3rd row of regular pistons. The pistons fire like in Mechanism 2; first the furthest pistons fire, pushing the middle pistons and the pistons closest to the column. Then, the middle pistons fire, and then the last pistons fire- moving the entire 3x3 area of sand. Next, the normal pistons retract. Then, the middle pistons (sticky) pull them in. Then, the furthest (sticky) pistons pull the middle pistons in- and then the middle pistons fire again from this piston to pull the normal pistons in. This allows for a 3x3 column of sand to rest easily without clogging the piston mechanism (and jamming/breaking it).
I put an extra 1x3 row of sand between this mechanism and thecolumn, so I can add a wall there if I want to. Having the extra 1x3 row does nothing since we're not pushing 12 blocks; it just lets us put the piston mechanism farther from the column while obtaining the desired effect.
Checkpoint: You now have Mechanism 1 and 3 in the off position, while mechanism 2a is off but has a gap between each of its piston rows. You also have a column of sand resting on piston 1, which has the 3x3 layer of dirt and a column of sand on top of it.
Mechanism 2b: This is the same as mechanism 2a, except its on the other side and stores the sand until its time to push it back. Now that there's a complete column again with no gaps, it triggers, pushing the sand back into the column, and using the dirt on the other side to push Mechanism 2a back into its starting position- so when it fires, it'll push dirt into the column and sand will push 2b into the compressed position (pistons fire and turn off, never remain in the on position- you can push a closed piston, but not an extended piston).
Now you have a column of dirt that's 1 layer higher than what you started with, and all the mechanisms are ready to run through again. Simply looping the end of Mechanism 2b to the starting trigger/memory unit for mechanism 1 lets it loop until it simply fires without moving/pushes sand out from mechanism 3 until the column there is finished, as the pistons in mechanism 1 can no longer raise the column (due to pistons pushing up to 12 blocks). And there's the elevator.
Video will be up within the hour, since youtube decided either the bad quality of my video is too ugly for it, or its just being mean...
Any questions/comments? I'm toying around with other methods that let the elevator go down and don't require sticky (or as many sticky, depending on how it works out) pistons... One idea is just having a simple 1x3 set of pistons pushing sand onto the column instead of doing the 3x3 dirt/sand combo... I'd still use 3x3 dirt, but would use a single piston to run 3x, loading sand in front of a 3x1 set of pistons, which then pushes sand and dirt. That whole thing would trigger 3x to get an area of sand into position, which may take longer, but makes wiring *much* simpler. The video will show how much circuitry and memory was needed for Mechanism 3 above- 5 sets of wiring, 3 for pushing the pistons out, all of which can be used for pulling it back in- but another 2 for getting them to withdraw in the right order... maybe more or less, I can't remember precisely. The difference between that and another loader would be, by having simpler circuitry, less concern over where it goes and more concern over moving the sand around, hopefully making it easier to remove from the system.
Edit: I now have a 1x3 loading system as well as an unloading system for the elevator, so it can go down... now to combine the two into one ugly, ugly machine.
Aug 6, 2010Posted in: Alpha - Survival Single PlayerQuote from noppa354 »scaffolding is easier than using the freezing method. build a floor one level below the top of the pit and cover it in water springs and then remove the floor. legit, doesn't need snow, and requires only enough dirt or whatever else you use to fill in that area
Read OP, that doesn't work. The water below the scaffolding will have a downward current, as opposed to still water. Try swimming in a pool made of scaffolding versus swimming in a natural lake or the ocean; the ocean will let you swim up and down at the same speed, but the scaffolding-built lake will let you swim down much faster than you can swim up, because the underwater tiles will not be source blocks, they'll be downward currents.
Aug 6, 2010I've been playing one file on hard mode, and had an epic map right off the bat. A dungeon had spawned near my spawn, down below a pile of sand (not on the beach, that was over another hill), and I looted the chests and set myself up a skeleton-harvesting room. Essentially I left the dungeon room intact but replaced one wall with glass, and had water set up to drag skeletons under. The problem I soon faced was that skeletons would spawn in the back of the room and never wander into the water; if I opened a whole next to the glass (I replaced a few of the cobblestone with wood blocks for easy access), just big enough for them to see through, they'd shoot at me- despite me being no closer than when on the other side of the glass. So today, much later in-game time, I decided to remedy this. I cut open the ceiling from above (I had replaced it with wood, so this was easy) and fell in; sunlight would set any mobs on fire, and I didn't hear anything.Posted in: Alpha - Survival Single Player
Until I landed.
Two skeletons were stuck in the water, and I presume the current changed the direction they were facing (stuck on a water source block and a falling/outward water block, each mob seemed to be able to semi-float on the source but still be fighting against current or something), and they were firing arrows. They didn't even manage to turn towards me, looking instead at each other. They then shot each other to death with at least 3 arrows each. I just sat there and watched. No screenies, unfortunately, since it went so fast, but still an awesome story.
Also, my fix for the problem of mobs spawning in the rear of the cave: fill the rear of the cave up with wool (or any ol' material), and then they can only spawn near the glass, where they promptly see me and drown themselves, giving me more free arrows. Yay science!
Aug 5, 2010Posted in: Alpha - Survival Single PlayerQuote from noppa354 »you can't get ice blocks... so not legit.
Yes, very legit. Water freezes, making ice. So you go layer by layer with the water, then build a roof so the snow stops falling. Now you break each layer of ice uninterrupted, and build the roof. It's painful if you're making an underground lake, but still fairly easy to do.
Aug 5, 2010Posted in: Alpha - Survival Single PlayerQuote from Evalora »Spawn a lot of ice blocks, place them in all of the air blocks you want to have still water, and break them. Should create completely still water.
That's actually the only legit way in this thread... Without using external tools you'd have to already have a snow map though :sad.gif: But definitely makes the most sense, since ice blocks break into water blocks, and water blocks freeze into ice blocks.
Breaking sand=falling water where the sand blocks were.
Aug 5, 2010Shakura posted a message on [Poll] Cobblestone vs Regular Stone; which do you prefer?http://www.minecraftwiki.net/wiki/FurnacePosted in: Alpha - Survival Single Player
Guess I was wrong about sticks, but this demonstrates the non-coal point better than that video does. Planks=best fuel ever, since it's renewable (thus defeating coal) and does the best of the renewable materials.
Aug 5, 2010Shakura posted a message on [Poll] Cobblestone vs Regular Stone; which do you prefer?Cobblestone walls I think look a bit better, stone floors definetly look better... Smelting doesn't take long, and doesn't take many resources. 1 log= 4 wood= 8 sticks = 4 smelts of cobblestone to stone, so you can easily smelt a ton of stuff if you cut down just a few trees.Posted in: Alpha - Survival Single Player
Aug 5, 2010Yeah... Actually I'm not sure if you can do it normally for a fairly large lake, given that destroying a block under a water block gives you a downward flowing block (which traps monsters better anyway...)Posted in: Alpha - Survival Single Player
I'd just use NBTForge, even INVEditing yourself some Still Water won't help with making anything more than 1 block deep. And if you collected the resources and cleared the area yourself anyway, it's really like you're doing it in-game...
Aug 4, 2010Posted in: General Off TopicQuote from Tails_Doll »Akward Zombie.
It's good comics.
Read through that one up to date, too... Wow I forgot a bunch. Then again, so many update fairly infrequently I just kinda come back every couple months to see what I've missed... Kinda nice that way.
Aug 4, 2010Considering you're playing a single player game, and each server is its own server... Read the rules and go ask someone in whatever server you're playing about it, can't discuss anything here. Also, if you're playing a *single player game*... go look up INVEdit, etc., which aren't considered hacks.Posted in: Alpha - Survival Single Player
