Block Placer & Breaker Mod adds four types of block which allow you to more easily create automated processes for destroying and placing blocks. The functionality of the different types of blocks are fairly easy to understand and so is the idea of usage.
These blocks will check if there is a block in front of it and if there is one it will be destroyed and placed in the chest. The only difference with the redstone breaker is that it will only act if there’s an active redstone signal.

These blocks check for blocks in front and if it’s an empty space a block will be taken from the chest and placed down in front of the block placer. The only difference between the normal block placer and the redstone block placer is the fact that the second only will act if there’s an active redstone signal.
