when the user finished level, show game time and earned points. i dont know how to make. please help.
Can help you with everything you need regarding time.
As for the score that is really up to how you want to track your score and how you want to display it.
What is the problem you are having displaying it? is it working with the GUI itself? you would display these numbers the same way you display anything else on the screen.
For any problems with actually displaying everything.
Maybe try to be a little more specific because I am not sure about the problem you are actually having.
