| + | So in the end that loop could control all the billboards and lights needed in a map. The flickering effect might be very small buff to levels looks for the headache it could cause, but keeping billboards connected into lights makes changing colors **MILLION ** times more pleasant. It can also be used to for example: cool scares and changing light coming from outside from day to night | ||
