Mojang have announced that they will be making some changes to the way redstone works in Minecraft Pocket and Windows 10 editions of the game. In the PC/Mac version of the game a redstone bug called quasi-connectivity has been used by builders to make all sorts of wonderful machines and contraptions.
Quasi-connectivity refers to placing a redstone power source or signal diagonally from a piston or any other block that needs power to work. You can then remove the power source and the block will remain activated – in a quasi-activated state and must be deactivated. This quasi-connectivity bug enables builders to create block update detectors which activate or deactivate once a block is broken, or a cake it eaten. The bug is very for making traps, and it is exciting news that it is being added to the Minecraft Pocket and Windows 10 editions of the game.
