Drawing Datapack
This datapack adds Paint which can be used to draw things in 3D!
How to use
To get Paint, you need to drop any dye on a crafting table. This will create a Paint item of the same color.
To use Paint, you need to hold the item and press F (to move it to your offhand). This will start drawing 4 blocks away from you. You can move around and rotate your camera to form shapes and lines!
To get an Eraser, just drop an Iron Ingot on the crafting table. Then, you can hold it and press F again to remove paint in front of you. The radius of the eraser is around one block.
