Good points The explanation is clear. Detailed. Clean. It seems to cover the most parts in detail in our country, from easy to difficult parts. As a beginner who is not good at computers, I have watched many Unity lectures in our country, but Retro's lecture is the most helpful. The lectures are continuously added and updated, so it is very beneficial. I definitely don't regret the money. Wishful thinking Beginners like me often think of the function first, find a function that fits it, think of the variables needed for that function, and write the variables later, but the lecture was a method of a skilled expert who wrote all the variables first, so it was a little difficult to follow. I think it would have been better if the lecture had been about building a big framework and adding flesh to it from a beginner's perspective. And there are often times when following the code is difficult, so it would have been more helpful if the lecture had asked appropriate questions to the students in the middle, so that the students could pause the lecture and try coding.
