Command Block

The Adventure Mode Control Block (name might not be final ) is a block that will be added in a future update. It is being made with the intent to support Adventure mode and will allow mapmakers to expand the interaction with the player through server commands. The block can run specified server commands when activated by redstone current. Considering its functionality, they will not be able to be crafted and only administrators will be able to place them.

Usage
The AMCB (Adventure Mode Control Block) will execute server commands like giving items or experience to a player.
