What did you take away from this lecture?

Great lecture in fact its been a great section took me back to the old days of computing when it was all assembler code and hexidecimal out of some game mag.The section was really cool, really liked the way you structured it to explain things it really simplified things and made a smoother follow along. I now understand serialization properly and BinaryFormatter etc thanks Sam keep it up.

Great explanation of hex and binary. I’ve been a software engineer for around 15 years, and this lecture took me back to my university days. I have to say, this was the clearest, most concise explanation of hex and binary I have ever seen, and I have seen it explained many times over the years. If this video was available as a ‘preview’ video on Udemy, I would share with several friends who would greatly appreciate it, or would appreciate showing it to their significant others who end up with a glazed expression when it comes up. :laughing:

Well done. Sometimes the actual explanation of how something works is the simplest one. I notice a lot of other courses try to abstract away or “simplify” various explanations but you’ve said it as it is, and finally there’s no more mystery or difficulty surrounding binarywriter, serialization and whatnot. It sounds simple because it is, and you don’t treat your viewers like idiots like some courses. Really enjoy your teaching style.

I think my takeaway, as if often the case with Unity: we stand on the shoulders of giants.

I really like making game with Unity. If I had to handle the ins and outs of binary and such myself? I wouldn’t go near it. Heh - I’m a big fan of driving the car, but not much casting the metal for the crankshaft.

I actually got my start in computers having no choice but to deal with Hex and Binary on a regular basis. This was back when old presidents were saying things like “Tear down this wall” and people knew what wall he’d mean. Things have changed a LOT over 40 years, and definitely for the better. While a good understanding of Hex and Binary is helpful, it’s definitely not required these days unless you want to get into bitmasking or understand how colors are represented a bit better.

I remembered the movie THE MARTIAN

Well, I think it would make the lives of quite a few students easier when it comes to RayCasting and setting up collision layers… :wink:

True, but strictly speaking, you don’t have to know how a bitmask works to set up collision layers, if you
