Create Cave Biomes ( Laggy )

Hello everyone! This is a tutorial to create cave biomes! Unfortunately, its generation method is a bit laggy and thats why i actually want to move to real coding. But still looks very good! For cave generation, you should definitely check my mod out 

https://www.curseforge.com/minecraft/mc-mods/caves-and-cliffs-mod/files…;

Nvm, let's get in this tutorial! 

What need:
- blocks and decorations for our cave biomes 
- cookies ( very important!!! )

Instead of custom blocks,im gonna use some vanilla blocks because they actually looks very good!

Im gonna use Grass Block only for the cave floor ( obvusly we dont want grass on the walls/roof ), Smooth Sandstone tor walls and roof and on the roof some random Diamond Blocks. Its just a test! Dont care about the blocks! Im also going to implement Red Tulip and Pink Tulip as floor plans and Leaves has hanging plans. Lets start!

Lets create a new block called "[cavename]_spawner". Mine will be... naturalcave_spawner! You can actually use the name you want, but im going to use that name :D

Im gonna use this texture for our block. Its the same, this block will be invisible for our player.
Dont change any value, go in tre triggers section and create a new "on block added" procedure.
Now its time to edit the procedure:

FOR BLOCKS:

FOR PLANTS:

Now we have created our custom block. At the end, add this:

OPTIONAL PART - RANDOM BIOMES

We are done with the procedure, lets now try it in-game! Start your game and place that block somewhere. Every time you place it, the blocks should be different!

Now try to run this command:
 

_{/fill ~8 ~12 ~8 ~-8 60 ~-8 mod_id:block_name replace stone}

This command ( Obvusly instead of mod_id use your mod id and instead of block_name use the name of the block you created ) will replace a cube of 16x16 around you ( in Y its from 12 to 60, but you can configure it so some biomes only spawn inside certain coords )

Now, check your caves in the ground, cool, ya?

Now lets create Another block!

Im gonna call it "Naturalcave_blockspawn" and gonna use same texture of the spawn. Create a procedure on block update tick and add the command we created before
(add the command via block "make console execute command")

_{/fill ~8 ~12 ~8 ~-8 60 ~-8 mod_id:block_name replace stone}

then a block that "place stone at x y z".

Now, yes, create another block lol!

"Naturalcave_structurespawn". Lets make same thing but no procedures. Just save it!

Now create a procedure "on player update tick"

make console execute command 4 times with this 4 commands:
_{fill ~-64 12 ~-64 ~-65 ~60 ~64 mod_id:Natruralcave_blockspawn replace mod_id:naturalcave_structurespawn}

_{fill ~64 12 ~-64 ~65 ~60 ~64 mod_id:Natruralcave_blockspawn replace mod_id:naturalcave_structurespawn}

_{fill ~64 12 ~64 ~-64 ~60 ~65 mod_id:Natruralcave_blockspawn replace mod_id:naturalcave_structurespawn}

_{fill ~64 12 ~-64 ~-64 ~60 ~-65 mod_id:Natruralcave_blockspawn replace mod_id:naturalcave_structurespawn}

Save procedure and we are done!

Now join the game, place the structurespawn and use structure blocks to save only that block! ( for the structureblock usage, check here: https://minecraft.gamepedia.com/Structure_Block )

Open options>resource packs>open resource pack folder
then go back to the minecraft "run" folder and go to saves/[yourworldname]/generated/minecraft/structure/yoursavedstructure.nbt

import this structure in MCreator and make it generate! Make it ONLY REPLACE STONE and you are done! ( you can also change The gen of the structure to find it in several biomes, or dimensions!). For any issue, join my discord server at https://discord.gg/3Af3Uer2Hj
