I'm doing a simple Levitation script just for fun.
For some reason, everything except the timeout works.
Even when I change the name of the timeout to something like "onAir" and use "scheduleEvent(0.05,"Air",null);" or changing the name of the timeout to "Air" and using "sleep(0.05); Air();" it just won't work.
Here's what I've got. Also, I don't care if you use this on your own server, just give me credit.

PHP Code:

//Scripted by Novice

function onCreated() {
  this.rep = {"walk","grab","pull","push","sit"};
  this.air = 0;
  player.z = 0;
  setTimer(0.05);
}

function onWeaponFired() {
  if (this.air == 0) {
    this.air = 1;
    for (i=0; i<this.rep.size(); i++)
      replaceAni(this.rep[i],"idle");
  }
  else if (this.air in {1,2}) {
    this.air = 0;
    for (i=0; i<this.rep.size(); i++)
      replaceAni(this.rep[i],this.rep[i]);
  }
}

function onTimeOut() {
  if (player.z == 2 && this.air != 0)
    this.air = 2;
  if (player.z == 1 && this.air != 0)
    this.air = 1;
  if (this.air == 1)
    player.z += 0.05;
  else if (this.air == 2)
    player.z -= 0.05;
  else if (this.air == 0 && player.z > 0)
    player.z -= 0.05;
  setTimer(0.05);
} 


Is there anything that looks wrong in there?
