How to See a Mob or Player Coordinates in Minecraft

Step 1: Let's start by creating 3 scoreboards to store each coordinate (X, Y, and Z)

scoreboard objectives add entityPosX dummy

scoreboard objectives add entityPosY dummy

scoreboard objectives add entityPosZ dummy

Tip: place these commands in command blocks lined up in the same direction and use a button

First: Impulse command block + button on it

Second and Third: Chain command blocks and enable Always Active

Step 2: To get the player's or mob's position, we will use the commands below. There is one command for each coordinate (X, Y, and Z)

execute store result score @p entityPosX run data get entity @s Pos[0] 1

execute store result score @p entityPosY run data get entity @s Pos[1] 1

execute store result score @p entityPosZ run data get entity @s Pos[2] 1

Do the same command block setup from the tip in step 1

Just set the Impulse command block to Repeat and Always Active to keep updating the coordinates

You can replace @p with @e and choose the mob you want, for example: @e[type=minecraft:zombie,limit=1]

You need limit=1 because we can only get the coordinates of 1 mob at a time

Because of that, it's a good idea to apply a tag to this mob

Step 3: The command below will be responsible for showing the mob's or player's coordinates in the chat

tellraw @p [{"text":"Entity coordinates: ","color":"red"},"\n",{"text":"X: ","color":"yellow","bold":true},{"score":{"name":"@p","objective":"entityPosX"},"color":"green"},"\n",{"text":"Y: ","color":"yellow","bold":true},{"score":{"name":"@p","objective":"entityPosY"},"color":"green"},"\n",{"text":"Z: ","color":"yellow","bold":true},{"score":{"name":"@p","objective":"entityPosZ"},"color":"green"}]

Just replace the @p inside the tellraw with the player or mob of your choice
