Adding Navigation

Adding Navigation, This is a useful technique that will be really constructive in my game. I understand this but for some reason when I do the code I always mess up the code of have some small mistakes. Plus trying it on a picky computer makes trouble. The computer that I have been trying to make my game on has some glitches and will not follow simple tasks. I have been following what the teacher has instructed to do in the clip he has put on the website. It is working on one computer but not the computer I work on. I would have to do it many times just to get it do what the teacher or I did on another computer. It also had problems with the files not being able to open on other computers. Since I had these problems and miss a few steps, I totally mess up each time. So, now I am going to go back at that step and learn what I missed. Hopefully then I can learn what I need and move forward. I have a lot to learn and it is very hard when you miss lessons to only try to follow the lecture and tutorials it always fills like I am missing something and I know when it does work. I try and try again. So After that I ask a friend to help me on this project but he did not have time to help and then I asked the teacher but it is seems to be to technical to help over line but hopefully when I get to the step I mess I can do it by self. But I think I can do it now. With my real project because Navigation is a must for my game and I will learn it, No Matter what.
