Shooting Range

This is a Shooting Range I had made in Minecraft. It features 3 Normal Shooting Rooms and 3 Long Shooting Rooms. The Long Shooting Range Has a Score Check to pick up the arrows and to check score because you cant see far not to much in Minecraft. This Also Has Reseting Buttons That Trow The Arrows To The Ground Not At You.
When You Enter There Will be A Villiger That Will Pick Up The Arrows ONLY For The Normal Shooting Ranges Witch are only 3. If The Villiger Dose not Pick up the Arrows Then You Have To Pick Them Up Your Self By Going to The Arrow Collecting That is Just behind the vileger (The Open Space). This Took Me Just 30 Minutes to make this so Diamond Subscribe And Comment.
