Hello there developers!
NOTE: this is my first community resource so I’m probably going to make a lot of mistakes
INTRO
I came up with this idea yesterday and it’s basically a mine block generation system. It’s not as advanced as in it doesn’t go down forever, but it does the job! I just believe it’s going to save you a lot of hassle.
Source Code
local generation = {}
-- weighted randomization
local function choose_random_item(items)
local total_weight = 0
for _,item_data in pairs(items) do
if item_data == "this is an ore table lol" then continue end
total_weight = total_weight + item_data[2]
end
local chance = math.random(1,total_weight)
local counter = 0
for _,item_data in pairs(items) do
if item_data == "this is an ore table lol" then continue end
counter = counter + item_data[2]
if chance <= counter then
return item_data[1]
end
end
end
generation.new = function()
local self = {}
self.rarities = {
signature = 'this is an ore table lol'
}
self.add_block = function(weight_table)

block_generation.lua (4.8 KB)
GET IT HERE:
Library
USAGE:
Constructor:
local module = require(path_to_module) -- requiring the module
local generation = module.new() -- constructing
Adding blocks:
generation.add_block({path_to_block, 1})
There's only one argument and that's a table with the first item being the block you want to add (can be a model or a basepart), and the other item is the rarity index (I'm using the weight technique so the lower the number the rarer it is)
Generate the cube:
generation.generate_blocks(path_to, 3, 3, path_to)
There's 3 arguments (and a 4th optional one). The first argument is the sample block. The code takes the sample block's size and position to generate the other blocks. The generation is going positively in all three axes, and the sample block is deleted after the generation is complete. The second argument is the height in blocks, and the third is the width in blocks. The fourth optional argument is the block container, i. e. the parent of the blocks. If not set the script will create a new one named "Block Container".
