This is partially true, a serverside triggeraction on an NPC is now received from every player who's using the V6 client. As a result, when updating attr values serverside I'm using it as an optimisation for V6 users, while using a timeout for V5 users:

PHP Code:

function updateSomething(){
  this.attr[3] = timevar2;
  triggeraction(this.x + 1, this.y + 1, "Update", NULL);
}

//#CLIENTSIDE
function onCreated(){
  if(graalversion < 6){
    this.setTimer(0.05);
  }
}

function onPlayerEnters(){
  if(graalversion >= 6){
    this.checkUpdate();
  }
}

function onTimeout(){
  this.checkUpdate();
  this.setTimer(0.05);
}

function checkUpdate(){
  if(this.updatetime != this.attr[3]){
    this.onActionUpdate();
  }
}

function onActionUpdate(){
  this.updatetime = this.attr[3];
  //stuff
} 


Might also be worth noting that for an NPC to receive a triggeraction, it requires a shape, which can be set by:

PHP Code:

//#CLIENTSIDE
function onCreated(){
  //32 pixels would be equal to 2 tiles
  this.setshape(1, 32, 32);
}
