Light Changing Script for Lightshow

[Struggler]

I made this for my lvl but dont know whats wrong, I tried using all players and just making it clientside, but it only affects the player who said it... Can someone help me out here? Make it so that when I say /lightson I'm not the only one viewing the lightshow?

PHP Code:

function onActionlightshow(){
  pl.seteffect(0,0,0.2,0.1);
  sleep(0.2);
  pl.seteffect(0,0.2,0,0.1);
  sleep(0.2);
  pl.seteffect(0.2,0,0,0.1);
}
//#CLIENTSIDE
function onCreated(){
  this.on = false;
}
function onPlayerChats(){
  if(player.chat.starts("/play")){
    this.playing = true;
    setTimer(0.2);
  }
  if(player.chat.starts("/stop")){
    this.playing = false;
    seteffect(0,0,0,0);
    setTimer(NULL);
  }
  if(player.chat == "/lightsoff"){
    if(player.guild == "Tree Bar Crew"){
      seteffect(0,0,0,0);
      player.chat = "Light effects turned off.";
      this.on = false;
    }
  }
  else if (player.chat == "/lightson"){
    if(player.guild == "Tree Bar Crew"){
      if(this.playing == true){
        player.chat = "Light effects turned on.";
        this.on = true;
        setTimer(0.2);
      }else{
        player.chat = "Light effects turned on.";
        this.on = true;
      }
    }
  }
}
function onTimeout(){
  if(this.on == true){
    for(temp.pl: allplayers){
      if(pl.level == "struggler-treehideout.nw"){
        pl.triggeraction(this.x,this.y,"lightshow",NULL);
        pl.seteffect(0,0,0.2,0.1);
        sleep(0.2);
        pl.seteffect(0,0.2,0,0.1);
        sleep(0.2);
        pl.seteffect(0.2,0,0,0.1);
        setTimer(0.2);
      }
    }
  }
}
