The Aquatic Update Update [​Discontinued]

• Load this mega-datapack into a new default vanilla world, and /locate an Ocean Monument.
• In survival, when you're closeby the Monument, you'll notice you'll get a beacon-like Conduit Power and Mining Fatigue. The idea was to make all Ocean Monuments as Mega-Conduit Structures. Yes, you get to breathe and see underwater for free.
• You can go into Creative, and navigate through the inside of the Monument maze. If you've explored a Monument before (highly unlikely, amright?), you'll notice that some of the rooms look much different. They are much brighter, and every dead end in the maze will always have a treasure chest of some prismarine shards and crystals.
• This is the first ever datapack to be able to change the Monument structure, since Monuments cannot be changed with datapacks using the structure files, I've changed it manually by code and by hand, post-generation.
• Then, you can navigate to the Core room, the biggest room (2x2x2) in the deepest end of the Monument. There are conduit particle effects around the structure in the middle. You can break it open: there is a spinning conduit core in its center. Right now it does has no function, but with some code, who knows?

• The first custom item that came to mind, the Enchanted Turtle Helmet can be acquired by smashing together an Enchanted Scute and a Turtle Helmet in a Smithing Table.
  
• This Turtle Helmet is usually a must-have for exploring all that this underwater datapack has to offer!
• The Turtle Helmet already has the same armor value as an iron helmet, and enchanting it with the Enchanted Scute will also give it Protection II, Blast Prot IV, Respiration V and Unbreaking II! 
• Besides that, it also has the attributes +3 Armor, +2 Knockback Resistance, +2 Armor Toughness and -15% Speed!
• When equipped, it also grants the player temporary Water Breathing as long as their head is inside any kind of ocean vegetation!
• This means that players can stay underwater for even longer to experience all that there is!

• Yeah the idea was to replace Phantoms and make them naturally spawning Sting Rays underwater! Their flight is so organic and smooth.
• But due to problems (discussed way below), I got stuck there.
• Nevertheless, Sting Wings are a special chest item. They are actually broken Elytra wings renamed as Sting Wings.
• But, they have a different texture being broken at 0 durability, they have an insanely high repair cost and they are Unbreakable. This means they cannot be repaired in an Anvil. Being Unbreakable, fascinatingly means they cannot be grindstoned into regular Elytra wings.
• However, they can still be repaired by combining two Elytra, so personally I just turned that off (because who ever combines two Elytra, destroying one precious Elytra?)
• While equipped, a player can sneak and poke their butt at a creeper, for example, and the creeper will get poisoned. Kinda useless, but it's hilarious.
• Besides that, the Sting Wings also grant +5% Speed and some +5 Armor.
• Eventually it would be nice to have more Poison-related effects.

• A pun on calamari and khakis, this is a custom black pants that upon equipping, mimics the squid's evasive maneuvers.
• If equipped, a player that gets hit will emit a cloud of squid ink particles, besides getting Invisibility and Speed if on land and Dolphin's Grace if underwater, to make a very quick escape.
• Nearby mobs and players in the ink cloud will also get the Blindness effect, while mobs will have their follow_range attribute set to 0 for a moment, de-aggro-ing hostile mobs, making them lose their tracking of the player.
• All squids will also replicate this behavior: meaning that you will get blindness if you attack a squid up close!

• The Dol Fin went through several iterations, making sure not to overstep on the Trident of Grace.
• It also gives you a small boost of Dolphin's Grace when quickly swimming upwards out of water!
• Now Dolphin's Grace doesn't actually make you resurface faster, because it actually only applies to horizontal motion. Yet, the Dol Fin incentives players to dive down deep into the underwater trenches...
• Still, underwater movement is critical wherever possible (there still must be ways to improve this)!

• Man, I love this thing. This is a special Riptide Trident.
• This is how it works: while swimming underwater, you must launch yourself into the air using the Riptide enchantment. Then, while you're still holding the Trident Of Grace, when you reenter the water, it will grant you a few seconds of Dolphin's Grace, allowing you to zoom at supersonic speeds underwater, and when your Dolphin's Grace times out, you can repeat the process of arcing yourself over the surface of the water.
• By rainbow-ing yourself across the water, you can clear a strait or even the wide ocean much faster (and more fun!) than using a boat. You'll never want to boat again.
• After doing this a few times, you realize: Mamma Mia! I'm a dolphin.

• I've changed the loot table of squids so that they drop special but ordinary looking ink sacs.
• You can combine these Ink Sacs in a Smithing Table with a Water Bottle or Mundane Splash Potion to make a Thick (Splash) Potion of Blindness (0:05)
• (It even works with brewed potions, like a potion of Speed, destroying the old potion effect in the process)
• You can then combine this Splash Thick Potion of Blindness with Arrows in the Fletching-Crafting Table to make Tipped Arrows of Blindness! This is integrated with the Cala-Khaki's features where it will cause particle effects and can cause mobs to lose their aggro too!

• A very simple feature, I made spiders walk on water.
• At night, you might try to shake off zombies and creepers by crossing a lake or ocean, but now, these spiders will relentlessly chase you even across water.
• Their movement is SO SMOOTH and it's SO SCARY because they easily catch up to you if you're swimming backwards.
• This forces players to go underwater to escape them, which hopefully incentives them to explore more features.
• However, it is extremely easy to just whack at the spiders from underwater. But you can do that in vanilla anyways. Besides, there would preferebly be more Drowneds and hostile mobs underwater as this is taking place.

• The player is granted Dolphin's Grace for one second when the player uses a Trident. This could be useful when fighting underwater with a Loyalty Trident: you can throw it, and then dodge any incoming return projectiles! (Might make it so that you need to also be equipping the Dol Fin)

• Let's promote the neglected seafood!
  
• Both types of cooked fish now fill six-half nuggets of hunger! Same as chicken!
• Dried Kelp gives 10 seconds of Water Breathing! This means that players can raid Ruins and Shipwrecks with less worry about their breath meter!
• If you are wearing even a normal Turtle Helmet, eating Dried Kelp will give you a boosted 30 seconds of Water Breathing! We need to push players to go underwater, giving them steps on how to earn water breathing!

• Rarely spawning in the musty underwater ravines, the new hostile Deep Trench are very scary.
• They defend the exposed veins of diamond ore that are plentiful in these underwater ravines, and since the pressure is immense, their bones have been solidified into some calcium-obsidian alloy of sorts.
• Usually in packs of 2-4, they move fairly quick on the obsidian-magma seafloor, but they have lost all flesh required to swim upwards against the water pressure.
• Since they can only move on the ocean floor, they take advantage of the magma bubble columns, pulling victim fish and amateur players downwards, making for a swift end.
• Being at the bottom of the ocean's water pressure, they boast a massive 20 hearts of base health, 0.5 knockback resistance, 9 attack damage and chain chestplate and boots: these guys are late midgame tanks that must be dealt with skillfully.
• Their boots shimmer with a light purple enchantment glow that contrasts the magma blocks' orange aura: they are enchanted with Frost Walker, making the Deep Trench immune to damage from Magma Blocks!
• Upon killing them, they will leave behind 1-4 Sea Pickles planted on the ground, lighting up the dark ocean bed with just a little more light. This means that, eventually, the ocean floor won't be so dark anymore!

• For every attempt of spawning a pack of Deep Trench, there is a 10% chance of spawning a sunken Iron Golem.
  
• No idea what the lore is behind this guy yet.
• It only has 20 points of HP, so it looks very cracked and neglected, stuck at the bottom of the ocean.
• Yet the golem will try to fight any Trench or Drowned that it encounters, winning the fights half the time. This brings some life to the underwater ecosystem!
• If you find one, you can repair it with iron and let it clean out the Deep Trench for you!
• It also has invisible Frost Walker, so it won't get damaged by the Magma Blocks either!

• Functions exactly like the Deep Trench, except that it only has 20HP and 7 base attack damage.
  
• I want to see these on the regular ocean floors, not so deep, but still another threat beside Drowneds!
• They can't swim upwards (or at all) and will stay on the ocean floor, but they can move very fast!
• I haven't implemented their spawning code yet. But they can be called from the function!

• It's basically all the things from my other datapack which has its own page! It provides a crafting GUI to the fletching table!
  
• But the highlights are, the Spear Bolt! These are special arrows that fly like tridents underwater, to aid you in underwater combat! They must be shot with a crossbow, and are crafted with prismarine shards as the arrow head.
• There's the Harpoon Arrow, which acts like a Spear Bolt but also leashes the mob that it hits to you!
• There's also the TNT Rocket, a modified version of the FIrework Rocket that causes an explosion upon impact!
• Just go to the page to see all the features!

• All Ocean Monuments will be converted into the custom Ocean Monument
• The Ocean Monument core room will have a "mega-conduit", a custom skull on an invisible wither skeleton. This ties in the lore of Conduits and the whole Monuments looking like pipes, and the Monument itself is like a mega-conduit structure. This is much better than the random gold blocks that were never an interesting incentive.
• Upon coming into proximity, players will get a constant beacon-like Conduit Power and Mining Fatigue III effect. (Unlike Elder Guardians who apply it every minute, the Ocean Monuments apply it every second)
• Players get Conduit Power near the Monument, allowing them to breathe and see. This is a purposeful decision, so that they don't worry about drowning and so they focus on the experience of fighting the mobs and raiding the Monument! Don't change this.
• Players who place doors or any other semi-air block to get air in the Monument will be given the Blindness effect.
• And, certain rooms in the Ocean Monument get a redesign (Sponge, DZ and DY) and post-gen variants (DY-a and DY-b), to make them look nicer.
• All dead ends (rooms with only one entrance/exit) will have a double chest of treasure, which can be changed to any loot table later.
• This takes a ton of calculation since there are no structure integrations in datapacks for Monuments, so the datapack must do it post-generation, in a similar way to my Desert Pyramid datapack. The code detects the area around the player every second for a Monument structure, and since Monuments always generates at y=39, it searches that grid for the northwest bottom corner of the Monument, and then relative to that position it locates each room "slot", detects each room type according to its unique positions of certain blocks (also accounting for rooms that are of variable sizes), then calculates how many open sides it has and then positions a /setblock at the precise relative coordinates depending on which position in a room (and which chest orientation) that the treasure chest looks most aesthetic in.
• The treasure chest will always be on the opposite end of the open side of the room (if the only opening of a room is towards the south, then the chest will be at the north end of the room, facing south) which is just great presentation
• If the only opening to the room is from the top or the bottom, then the code will randomly pick a side (North, South, East, West) to place the double treasure chest, using the bedrock pattern as randomiser. This means, if you load the datapack into two copies of a world that has generated the Monument, then it will always place the chest in the exact same orientation (as well as the post-gen variants of DY-a and DY-b). This took so much big brain but it looks so good
• I've not done the redesigns of the DXY or the DYZ megarooms yet. They definitely need some cleaning up, but they're so rare that I've only encountered them in videos. Chest placement is gonna be tricky. So you'll need to make them look good too!

• Periodically executes at all players in the deep ocean biome, with a predicate that tests for any nearby monument, unless the cornerstone armor stand of an already initialized monument is present. (to prevent re-initialization) and calls the next function, prox_20t, which tries to narrow down the possible cornerstone coordinate of the monument, and all that jazz is described above.
• Periodically changes the max_health attribute of all naturally spawning Guardians to 12 Hearts instead of the insane 15 hearts. There's a more efficient way to do this, please correct this. I chose 12 hearts according to how many Trident throws it takes to kill a Guardian (way too many to make tridents useful!)
• Periodically checks for any survival/adventure mode players nearby a monument with a y-coordinate between [​30..64] and calls a function to apply conduit power and mining fatigue for five seconds, every one second.
• Periodically applies blindness to all players in the monument who are in a semi-air block like doors. This is an early method to discourage using doors to get air, but now that players have conduit power, we can scrap this command.
  

• The auxil path just contains some developer helper functions that help me get the relative distance between two coordinates, which helped in identifying the unqiue blocks in each monument room structure. Made that so much faster.
• 25rand.mcfunction was a function that helped test the randomness of the bedrock pattern by executing it at a hundred armor stands in a 10x10 horizontal grid. It's 28-24-24-24 chance, but that's close enough.

• At the very top is the first idea to make all Drowned-thrown tridents lodged in the ground become pickup-able, as prismarine regular shards, just like how you can pick up player-shot arrows. It does go against the logic of skeletons shooting "ghost" arrows, but I do like the idea that Trident Drowneds are not throwing Tridents, but rather Harpoon Arrows, since in my other datapack, you can craft those with prismarine shards.
