Carry On Mod 1.12.2/1.11.2 allows you to pick up Blocks and carry them around with you.
Ever wonder why you can carry a stack of 64 empty chests in your pocket, but you canit move a filled one with your bare hands? Well, this mod is for you.
This is a simple mod that improves game interaction by allowing players to pick up, carry, and place single block Tile Entities (such as Chests, Furnaces, Droppers, Hoopers, and your favorite machines from other Tech Mods) using only their empty hands. No items (or pickaxes) required. States, meta data, inventory and NBT data are retained. It also allows you to carry around smaller mobs.
How to install:
Make sure you have already installed Minecraft Forge.
