---- OTHER THINGS YOU MAY WANT TO KNOW ----
This datapack contains two main functions : fill2d and fill3d. These functions makes filling area or volume much easier. Here are two precise explanations :
Type "/function bf:fill2d" with the block you want the shape to get filled with in your main hand. It has to be a closed shape like on the exemple below.
Type "/function bf:fill3d" with the same conditions and be sure to be in a 3D closed shape.
Here is an example of what you can do :

Then, by typing "/function bf:fill2d" with the block I want to use to fill the closed shape in my main hand, I get :

Todo list :
- DONE : A way to undo in case you forgot to close your shape or if you misplaced your player when executing one of the commands
- A function to change the limit of blocks for the commands
- A function to make it possible to fill with random block from your inventory
- Make it possible to fill vertical 2D closed shapes
- Make other versions available (cause not everyone uses snapshots to play ahah)
- Maybe some of your ideas... :)
