Minecraft Command: The Complete Strategy Guide – Trick #36: “Using Selector Condition Filters to Specify Command Targets!”

“Using Selector Condition Filters to Specify Command Targets!”

How to Set Up the Command Blocks

Command entered in the Command Block:

Command Block A1

Block Type: Repeat / Redstone: Always Active
/execute as @e[type=splash_potion] at @s run kill@e[type=armor_stand]

➡️ This removes the previously existing armor stand so that the subsequent processing can be carried out correctly.

Command Block A2

Block Type:Chain / Redstone: Always Active
/execute as @a at @s if entity @e[name="Nether Star",r=2] run scoreboard players set @s star 20
➡️ This makes the armor stand appear at that location only when the splash potion hits the ground.

Command Block A3

Block Type:Chain / Conditional / Redstone: Always Active
/kill @e[type=splash_potion]
➡️ This causes Command Block A2 to succeed, and the potion is removed immediately after it hits the ground and the armor stand is summoned.

Command Block B1

Block Type: Repeat / Redstone: Always Active (Delay in Ticks: 20) 
/execute as @e[type=armor_stand] at @s run tag @e[family=mob,rm=0.1,r=20] add target

➡️ This allows you to mark the mobs around the armor stand as targets.

Command Block B2

Block Type:Chain / Redstone: Always Active
/execute as @e[tag=target] at @s run tp @s ^1^^0.2 facing @e[type=armor_stand]
➡️ This makes the mobs move as if they are being pulled in while rotating around the armor stand.

Command Block B3

Block Type:Chain / Redstone: Always Active
/execute as @e[type=armor_stand] at @s run kill @e[tag=target,r=2]
➡️ This causes mobs that approach the armor stand to be defeated as if they were being sucked into a black hole.

Command Block C1

Block Type: Repeat / Redstone: Always Active
/effect @e[type=armor_stand] invisibility 1 1 true

➡️ This makes the armor stand invisible, allowing you to create an effect where the true form of the black hole cannot be seen.

Command Block C2

Block Type:Chain / Redstone: Always Active
/execute as @e[type=armor_stand] at @s run particle minecraft:evoker_spell ~~~/

➡️ This creates a magical effect from the invisible armor stand, enhancing the black hole illusion.
