Minecraft player looking for command?

I need a command that recognizes whether a player is in a certain area. Java version 1.16.4

Searching for contacts is prohibited at girlfriend

Believe it works if you write this:

/ locate "player name"

At least helped me with biomes, fortresses, etc.

Please read the question again

This is also not a contact search that he makes.

This is only for biomes and buildings

It has nothing to do with it xD

/ execute if entity @a [x = 0, y = 0, z = 0, dx = 0, dy = 0, dz = 0] run (command)

from

x, y, z = first block

until

dx, yx, zx = second block

a player is detected
