How Do I Make a Block That Breaks a Block In Front Of It.

I Want To Make a Block Breaker In Mcreator And So I Made A Block That Looks Like a Piston And Also Made It Able To Rotate Based On The Direction The Player Put It On.

Then I Did The Procedure Thing I Came Up With a Issue That I Cant Break The Block In Front Of The Block Because If I Do "x = 1" Then It Will Break The Block beside It But Not At The Front. I Want It To Break The Block In At The Direction That The Block Face Is Pointing At.
