This time, while taking the professor's GAS lecture, organizing the content and looking at the code inside the engine, I thought that even if you don't necessarily use Unreal Engine's GAS, just learning it and understanding its structure will be a great help to your programmer's ability. After overcoming the difficulties of first use, I think I found a way to greatly shorten the development time and testing time with excellent efficiency and flexibility. Thank you for providing a great lecture!
