You have access to petabytes (That's thousands of terabytes) of data freely available to you over this magical thing called the internet. I can guarantee you that any problem you have with unity can be found by searching through google, and if it can't be found through searching google, making an account on a unity forum and asking your questions there will have it sure to be answered. I can guarantee you they'll be able to give better answers because they are the unity forum, just like we can give better answers on torquescript because we are literally the biggest resource for torquescript on the entire internet.
Also documentation.
