obj.hide() problems

[xAndrewx]

I'm having some problems with the

obj.hide()

It's finding the NPCs (using a loop)

for (temp.i: npcs) {
  if (temp.i.isinclass("event_block")) temp.i.trigger("onToggleVis", true/false);
}

in the NPC

function onToggleVis(mode) {
  if (temp.mode == true) this.hide(); 
  else this.show();
}

Although, it calls the function (onToggleVis) but it won't hide the NPC. I saw this

obj.hidetoclients = boolean

when I set it to true, it hides no problem. It just won't come back!

Thanks
