Solved Chack if the player is within a certain area

I want to make a survival Server with a spawn.
I want that wen you break a block in the spawn, it will cancel the event,
but I don 't know how to check if the player is within a certian area.

my spawn is x: 10, z: 10 to x: -10 and z: -10

if (someoneCouldHelp == true) {
player.sendMessage("that would be cool!")
}

 

Listen for BlockBreakEvent check if player is within the spawn location, for example:

PHP:

if (Math.abs(playerx - certainlocationx) <= 3 && playery - certainlocationy) <= 3 && playerz - certainlocationz) <= 3) {
    // Player is within a 3 block cube of location.
} else {
    // Player is not within a 3 block cube of location.
}

If player is within the location cancel the event if not just return.

Or just use Location#distance(OtherLocation )<=3

 

Thank you! it is solved!
