Get Shape Util

This datapack allows you to get a shape of (almost) every block in the game. This was made for 1.18.2, might work on earlier ones as well (didn't test).

How to use

It's pretty easy to use, you just simply use getshape:shapegetter loot table wherever you want, and it will drop stone with the data. The path to the array of boxes is tag.boxes, and a box is formatted like this:

{
  min: [x, y, z],
  max: [x, y, z]
}

(inside those coordinates is the box, for more complicated blocks like the stair, there are more boxes)

Quick example

If you stand on a slab then run this command

loot give @s loot getshape:shapegetter

Then check the stones data with this (assuming the stone is the first item in your inventory)

data get entity @s Inventory[0].tag.boxes

This is what you get.

[{max: [1.0d, 0.5d, 1.0d], min: [0.0d, 0.0d, 0.0d]}]

Example function (is_in_block)

I made an example function that checks if an entity is inside a block or not called getshape:is_in_block. The result is inside a scoreboard, with the name output and with the objective getshape.temp. ( 0 = false; 1 = true; )

You can check the source code, for a better understanding on how this works.

Exceptions

The reason that there are exceptions is because not all blocks have always the same shape/collision box. These are the blocks that have position/context specific shapes, for these blocks it will return as it would be empty.
