ArmorStand moving around a middle block

I am trying to make the armor stand rotate around the block, and not start rotating from it, which is what is happening.


I trying to do anythig similiar to that
But the max who i achieved is this why my armor stand doesnt rotate around the EnderChest.

Use your getCenter() method. But you'll have to make some adjustment: the "relative" coordinates should always be +.5 not negative and the y is probably not 0.5 because of the height of the armor stand. You'll have to play around a little to find the best offset
