Now that might be a lot to take in let me explain some of the other details

With the get block at x y+1 z you can change the direction and distance you can check for a certain block in by changing the number seen in the gif you can also put the x or z block in the position of where the y block was in the putcoordblockhere+1 block

Now you've got your base to check for a block or blocks in a certain direction

Personally i like to make a 2x2x2 model for my multiblock but you don't have to. So to place the blocks for the multiblock you have to do this for every position you checked for a certain block in

Now make 2 or more blocks that you want to be placed when you build the multiblock always have that 2nd block as a corner. with the 2nd block make a procedure for update tick and set the tick rate to 1 then check for air at the positions where the blocks of the multiblock are then set when any part of the multiblock is broken set air at those block positions and you're set

Hopefully this wasn't to confusing if you are confused comment and let me know
