Deconstruction mod adds in the world Minecraft Pocket Edition block of deconstruction, which has the function and the ability to deconstruct a ready-made blocks and objects. When there is a deconstruction of any unit, which has been done in the workbench, it is decomposed into all those elements that were used to create the element.
This is a very useful mod because you can disassemble the elements made of any block or item in the workbench getting all the resources back.
How to use? For the beginning in the workbench make Deconstruction unit, and then place it on the ground. Tap it once to open Deconstruction graphical user interface (GUI). Select the check box next to the grid 3 × 3, and will start, click on one of the units or element that you want to disassemble. For this you need to have at least some sort of block or object in its interface. To obtain the disassembled things need double clicking to click on things parsed in the grid 3 × 3. Exit the GUI or select a new location for deconstruction.
