Property in realtime

Hey guys i have a problem i am newbie at python with blender. I want to have it track to a different object for a different int value.

import GameLogic as g

get controller

cont = GameLogic.getCurrentController()
own = cont.owner
y = own[“Int”]
x = “Empty1”

get actuator attached to the controller named RaceCam

act = cont.actuators[“123”]

set object being tracked

act.object = x

activating the actuator

cont.activate(“123”)

if y == 1:
act.object = “Empty11”
