Centering a nickname?

[devilsknite1]

So I was wondering (no matter the length) how I would go about setting a custom nick name right below the player, like the default one would. It's through a gani, btw

PHP Code:

SCRIPT
function onPlayerEnters() onTimeOut();
function onCreated() onTimeOut();
function onTimeOut() {
  if ( player.level.name != NULL ) {
    showText( 300, player.x, player.y + 3, "verdana", "b", player.nick );
    changeImgZoom( 300, 0.6 );
    changeImgColors( 300, player.clientr.( @ "namecolor_colors" )[ 0 ], player.clientr.( @ "namecolor_colors" )[ 1 ], player.clientr.( @ "namecolor_colors" )[ 2 ], 1 );
  } else {
    hideImg( 300 );
  }
  setTimer( 0.05 );
}
