Well, it's about time for another 'make Cauldrons useful again' thread. Here we go.
My proposition is to implement a new use for Cauldrons - precipitating crystals from Glowstone or Redstone. The crystals will be injected into currently existing recipes as well as be used for new items. Just sort of thought that crystals would make some cool decorations as well as make a lot of sense as redstone components.
To set up a Cauldron for crystal precipitation, you first need to have a Cauldron full of water. If you are making Redstone Crystals, it will need to be at least in contact with one block of fire - below, or to the left/right/front/back. For obvious reasons, the fire can't be on top of the cauldron.
Then, you need to right click the water surface to insert either Redstone or Glowstone Dust. The water will turn red or yellow, depending on what you inserted. You can only insert one dust item into each cauldron, and once inserted it cannot be removed. A bucket cannot be used to obtain the dust solution. Breaking the Cauldron will permanently destroy the contents.
Then, you will have to wait one real-time minute. As time passes, the water level will slowly drop, until all water is gone and a single crystal is left at the bottom of the Cauldron. It will look like an item, but it cannot be picked up by normal means.
Afterwards, simply right click with an empty hand on the crystal to make 2-3 of the crystal item pop out of the Cauldron, then pick it up.
Using Crystals as Decoration Blocks
By putting four crystals in a square shape within a crafting square, you get a crystal block (Redstone Crystal Block or Glowstone Crystal Block). It can be placed anywhere, and they emit light equivalent to a block of Glowstone.
The texture of the crystals are similar to an emerald block. The Redstone Crystal Block would have a pale red tint, while the Glowstone one will have a pale yellow one.
Both crystal blocks are translucent like stained glass.
Recipes Involving Crystals
Well, here are several preexisting recipes changed. Not really any point. Some of them I just thought that the original recipe made no sense, while for others I felt that the block ought to have crystal components inside them.
Redstone Lamps will have the Glowstone Block replaced with Glowstone Crystal.
Daylight Sensors will have a Redstone Crystal replacing the central Quartz.
Weighed Pressure Plates will have a Redstone Crystal placed underneath either of the metal bars.
The Beacon will have a Redstone Crystal and Glowstone Crystal replacing the middle-left and middle-right glass blocks respectively.
And below are new recipes:
Crystal Sculptures are similar to paintings in that a random shape is picked when placed. They drop naturally when broken. Possible shapes are:
1. Creeper Sculpture
2. Zombie Sculpture
3. Skeleton Sculpture
4. Zombie Pigman Sculpture
5. Enderman Sculpture
6. Steve Sculpture
Quartz is any crystal. Has to be the same type; the sculpture will appear as the same color as the crystal used.
Crystal Transceivers are basically wireless redstone signals transmitters. However, their uses are limited since there is only one 'channel' in which sending a signal to any one transceiver creates a signal in all other loaded transceivers. They could be used as possibly a rescue signal (in small SMP servers) or as a 'wake-up call' to bases with lots of mechanical devices, turning on the lights and everything.
Fire-res potions are Glowstone Crystals, health potion is a Redstone Crystal.
Crystalline Apples are an alternative to Golden Apples. However, instead of providing 'buffs' such as strength and resistance, it simply refills your hunger and saturation fully as well as 5 hearts of health. Sort of cheap, but whatever.
Fire-res potions are Glowstone Crystals.
Logic Gates are... logic gates. Anyone familiar with redstone should know most of these. Just some convenient devices to help redstoners. Thanks to AMPPL50 for suggesting this.
As usual, fire-res is Glowstone Crystals, health is Redstone Crystals.
Now I realize this is sort of a wishlist with a common theme, but... it's a common theme. Yeah.
Transceivers should have several channels, as they would be very useful at making more compact circuits.
Redstone Crystals should also replace redstone dust in the recipe for redstone torches, as a lot of circuits require massive amounts of redstone torches to work.
Another use could be to make transistors, and at making logic gates.
I didn't propose replacing redstone dust in the more 'common' recipes precisely because a lot of circuits require massive amounts of them. It would be a tad annoying to have to sit around waiting for cauldrons to cook all day in order to make redstone stuff in survival.
However, the logic gates idea is interesting. How would you propose going about doing that? There are quite a few logic gates. Would there be a separate recipe for each of them?
Simply use more cauldrons. In the end, the result would be cheaper circuits.
Logic gates would indeed have a separate crafting recipe for each. They would have 2 inputs and an output (If more inputs were needed, linking logic gates to each other would be quite easy).
True, you could use more cauldrons. At a large scale it would probably be cheaper and more efficient, but for a regular player just trying to make a sliding door or something it would be annoying to create a cauldron room just for that device.
Maybe have both recipes usable?
I'll think about the logic gates. Maybe experiment with crafting recipes a bit.
