I have made a 2D Game using unity in which user has to select objects of similar color and now i want to display hint when user is unable to select the color for more than four seconds.
I want something similar to candy crush hint displaying system in which candy crush shows hint by highlighting the possible combination if user is not able to identify any combination himself.
I cannot figure out how to find if the user is inactive so that i can display hints.
I would really appreciate if someone can help me in figuring it out. Thanks in advance.
