How to make a number decrease every second in C # under unity?

Question

Unity

I am making a character satiety script and I need the number to decrease by one after some time and at the end, when the number is exactly 0, some actions are performed. Who cares about the time please tell me how to do it.

Answer 1

1) Read a book on C #, something for beginners
2) Understand what Update, TIme.deltaTime is in any way possible, for example, using unity tutorials
3) Paint the algorithm for what you need with an eye to paragraph 2
4) Implement the algorithm.
The question is not only primitive, it is also a task. If you can’t implement this, then it’s too early for you in game development

Answer 2

Yes, what's incomprehensible here, you divide Time.deltaTime by Time.deltaTime you get time.
