Block Data Hacker Mod is a fun mod which can be used both in singleplayer and in local multiplayer. Basically it lets you modify the block data of blocks and activate an animation. It’s the perfect way to prank your friends!
How does it work?
Once entering a world there will be two new buttons in the bottom-right and left corners: SELECT and HACK/[ON/OFF].
There are mainly two things which you can modify: block data and animations.
Block Data: Tap on the block which you want to modify and then press SELECT. A window will popup where you can input the a block data.
Animations: Tap on a block which supports block data (basically any block which exist in multiple colors, animated states or which can face different positions). Then press HACK/OFF to enable an animation. To switch it off, simply press HACK/ON.
