Setup for a prank on a friend. :)

os.unloadAPI("sensors")
os.loadAPI("/rom/apis/sensors")
targets = sensors.getAvailableTargetsforProbe(controller,sensorName,probeName)
while true do
-- Loop through this list of targets getting the info about each one
for i=1,# targets do
  -- Get the target data, i.e. x,y,z coods and type
  targetData = sensors.getSensorReadingAsDict(controller,sensorName,targets[i],probeName)
  -- If the target is a player, i.e. has the name "vq" then check if it is close
  if targetData["name"] == "hosscat"  then
    rs.setOutput("bottom",true)
  elseif targetData["name"]
    os.reboot()
  end
