how to check time for idle app

Danikanama

i want to make a game that runs also when its inactive(like idle games that you earn resourses even when youre not playing)

how can i count or check how much time has passed since last loggin?

HNJ

using Time.time

It just return amount of time in seconds passed from the launch of application. For example:

float startTime = Time.time();
// Do stuff
float endTime = Time.time();
Debug.Log("Time taken: " + endTime - startTime);
