hmmm
just do in a script

function onCreated() {
  this.b_area = {2, 2}; //32x32 px
  this.join("block_area");
}

in the class

function onCreated() {
  this.setShape(1,16 * this.b_area[0], 16 * this.b_area[1]);

  save[1] = this.b_area[0];
  save[2] = this.b_area[1];
}
//#CLIENTSIDE
function onCreated() {
  this.setShape(1, 16 * save[1], 16 * save[2]);
}

Shouldn't cause any lagg
