$issuer its the user or console that its doing the command/action $issuer->level its the level that the player its i think
$issuer->level just gets the level name so if u wanted to set it to a variable. PHP: $level = $issuer->level;return $level; That would return the level name of the player who excuted the command.
but the $issuer would tell you the player|console name but like this $issuer->level it would tell you the world that the user|console are in
I think you find the level by either: PHP: $this->api->level->get($issuer); or PHP: $issuer->level; I think that should work the same
