Creo que falta entrar mas en detalle sobre que hacen ciertos métodos. Hay poca explicación.

By Dmitry Berestennikov on 12/19/2024

This course shows brilliant practices and important aspects of Unity Tools scripting. But it has some disadvantages: 1. There is no explanation of what is going on in code while showig it to me as a stuident in most of the cases. So I have to search for answers myself. As a result, that means, this course just shows how to script, but doesn't teach it. 2. The first and the last video in each section has just no sence: author tells what will be done and what was done. But that doesn't help any way. While watching videos you understand the aim anyway, and of course you understand the final result in the end whithout additional explanations of "what we have done today". Thank you for your hard work and I hope you'll take into account my comments :)

Solid and to the point. Lots of info packed into short amount of time. No fluff

By Maxime Brind'Amour on 6/26/2024

Yes, but but I think it was lacking a bit of explication on the code we were actually writing.

By J B on 4/28/2024

Good course overall. Short (3-ish hours) but the pacing is fast so it covers more ground than you'd think. The trade-off for the fast pacing is that it's more of a code-along than a course most of the time. The code gets read out loud as it's being written but not really explained. Doesn't really go in-depth on many of the concepts either but it does expose you to many different editor scripting aspects which is great. Expect to do a decent amount of documentation digging on your own though to really grasp the concepts being covered. Most of the course is on IMGUI. Barely touches on UIToolkit / UIBuilder (8 total minutes). This may or may not be a good thing depending on your preferences but it's not quite what I expected from the course description. Each section has a great overview of the features of the tool being made at the beginning which is something I wish more Udemy courses had. In my opinion, this is more of an introductory course than a "Beginner to Export" one. I don't think I'd call myself even an intermediate after completing it and certainly not an expert, but I would recommend to anyone wanting to get started with editor scripting.

If I could give this course than five stars I would. The instructor is flat out BRILLIANT!
