I write another script with another names for game scene but even I copy event system it doesn’t work. I know if I copy all the start scene elements it will work but I wanna do it all fresh. How can I add an event system? I have to know this because just need it.
SOLUTION: You can make another eventsystem from game object>ui menu and so you can write another script for another scene. I do it because it will make me free in a seeable future when I need independent events in levels and method or functions
