I will use an example with /tellraw but also i didn't work with commands like /playsound and it broke a lot of systems
How to reproduce
1. Place a command block or paste in chat
2. put /tellraw @a[x=1430,y=56,z=2234,distance=2] {"text":"Example"} (Where 1430, 56 and 2234 are x y z coords of your map)
3. Press enter and it will appear "No player was found"
Also if you dont put the "distance=2" it will output the text "Example" even if you dont are in the coords
distance
is a range. Setting it to 2 will cause it to only look for targets exactly 2.0 blocks away, no more or less. Usedistance=..2
to get a range between minimum (0) and 2.
