UFO Code

Im making a Zombieland Ultimate Edit (still learning so please be kind. Offer constructive Critasism)

Iv got this as the function for UFO mode would i need anything else or just this.

Also if this is correct how could i get this to be HOST only.

ToggleUFO()
	{
	  self endon("disconnect");
	  self endon("death");
	  self endon("disableUFO");
	
	   self.UFO = booleanOpposite(self.UFO);
	   self iPrintln(booleanReturnVal(self.UFO, "UFO Mode: ^1Off", "UFO Mode: ^2On^7nPress [{+frag}] To Move!"));
	
	   if (self.UFO)
	   {
	    self.parentObject = spawn("script_origin", self.origin);
	    self.parentObject.angles = self.angles;
	    self PlayerLinkTo(self.parentObject, undefined);
	    self disableWeapons();
	
	    for(;;)
	    {
	    if(self fragButtonPressed())
	    self.parentObject moveTo(playerAnglesToForward(self, 25), 0.05);
	    wait 0.01;
	    }
	   }
	   else
	   {
	  self unlink();
	  self enableWeapons();
	  self.parentObject delete();
	  self notify("disableUFO");
	   }
	}

iv got a feeling iv got somthing missing but i cant put my finger on it.
