Hi guys, I have a Unity project. I need help to create 3 functions

The second and third ones are not necessary but if you can help me about these two functions it would be great. BUT THE FIRST ONE IS THE MOST İMPORTANT AND IRGENT.

I need help about these functions. I only need functions and a simple explanation of the lines. I have only 10 dollars budget. Can you help me?
