void SetcountText();
Don't put a semicolon after a method signature.
ok didn't see that ;) now it works like a code,but the game stops every time i collect a pickup object... it'says like this ----NullReferenceException: Object reference not set to an instance of an object PlayerController.SetcountText () (at Assets/_scripts/PlayerController.cs:35) PlayerController.Start () (at Assets/_scripts/PlayerController.cs:14)
drag and drop your text object to your public CountText in the inspector.
