canbepushed(); doesnt work if theres a wall on each side??

[scriptless]

PHP Code:

Script help for '*push*':
TServerNPC.canbepushed()
TServerNPC.cannotbepushed() 


Using this serverside and noticing that a "block.png" cannot be pushed thru a gap that is 2 tiles wide dispite the fact that it would fit.. Does anyone know if there is a solution for this?

PHP Code:

function onCreated() {
  canbepushed();
}
