So how do I get it to go the right amount of blocks on its way back? Im sorry im asking so many questions. Im desperate to get this working. Ive been working on it for forever >.< I also need it to go forward the right amount of blocks so how do I do that since "y = math.floor(x / 8)" doesnt work…right?

Im really having trouble getting it to come back to the chest. It either doesnt go far enough to get to the chest or it overshoots it and I dont know why it does that.
