This mod adds 2 blocks: Relocator and Platform. They can be used to move blocks in the world. Platform is responsible for grabbing blocks, while Relocator is responsible for movement of Platforms.
Relocator works when it receives a direct redstone signal. It has a UI where you can set movement directions.
Platform's sides can be toggled by an empty hand. A platform will grab blocks adjacent to its open sides. It will also grab any entities above. If you sneak while placing a platform, its back side will be closed after placement.
Both blocks are in the Transportation creative tab.
Relocator recipe is a piston with obsidian:
This mod serves as a base for sub-mods and has a simple API for people, which allows creation of other movable blocks. More details are in the GitHub repository.
