1/ How to make a working barrier


1: /clone X Y Z X Y Z X Y Z replace
X Y Z : first coordinates (with the smallest values)
X Y Z : second coordinates (with the biggest values)
These represent the area to clone.
X Y Z : third coordinates
The coordinates to where to clone.
replace : delete the blocks before.

1;2;3;4;5;6;7;8;9 : the different steps of the barrier's movement.
(I will make a clone tutorial soon)

2: /testforblock X Y Z lever N (CommandBlock: repeat ; always active)
X Y Z : coordinates of the lever
N : the value of the lever
-if the lever is "on": 1 (east), 2 (west), 3 (south), 4 (north)
-if the lever is "off" you add 8 to the value: 9 , 10, 11, 12.
(To see the direction of the lever use fn 3 and point the lever, after re use fn 3 to come back at the normal mode)

2/ How to make a working machine gun

1: /kill @e[type=Arrow,score_MGBK_min=1] (CommandBlock: repeat ; always active)
Kill the arrow with the MGBK score.
2: /scoreboard objectives add MGBK dummy
Add the MGBK score.
3: /scoreboard players set @e[type=Arrow,name=MGB] MGBK 1 {inGround:1b} (CommandBlock: repeat ; always active)
Set the score MGBK to 1 for the arrows with MGB custom name (the arrows who sent the MG) and which are in the ground.


1: /testforblock X Y Z lever N (CommandBlock: repeat ; always active)
Come back to 1/ 1:
