pri svojem ustvarjanju sem naletel na problem, kako update-ati večje število objektov(enemies), pod pogojem da igra seveda normalno teče. Objekte sem shranil v "List" in jih potem v main classu z zanko vse update-al, vendar je že v primeru da je bilo aktivnih 8 objektov igra začela močno štekat. Zanima me kako se vi, bolj izkušeni programerji, lotite takšnih problemov.
