Mam taki mały problem z popularnym wskaźnikiem BetterVolume 1.4.
Mianowicie liczy całość w sekcji Start() co każdy tick mocno obciążając CPU.
Przerobiłem go tak że dodałem sekcję OnTimer() w której co 10 sekund uruchamia się funkcja licz(). Wszystko co było w Start() przeniosłem do licz() tak że obliczenia są robione co 10 sekund i wszystko jest ok ale po naniesieniu na wykres wskaźnik czeka te 10 sekund zanim naniesie wartości.
Dodałem do sekcji OnInit() aby od razu wykonał pierwszy raz funkcję licz() a i tak indykator najpierw ma zwłokę 10 sekund a dopiero rysuje wartości.
Jak to poprawić aby na starcie policzył raz a potem co ileś tam sekund ?

już o tym zapomniałem i używałem po staremu, sprawdze i zobacze
