Okay so I'm trying to test a code so that when my "Cube" or player or cursor or whatever is near the Empty, it will turn the music on or off, so far I've been unsuccessful, I'm very new to coding and need some help

Here's the code I tried:

Code:

import bge def main():     cont = bge.logic.getCurrentController()     own = cont.owner     player = bge.logic.getCurrentObject('Cube')     sens = cont.sensors['Play']     actu = cont.actuators['Music']         sens.distance = 0.50     if sens.positive:         cont.activate(actu)     else:         cont.deactivate(actu) main()
