Any opinions on this book

Well let’s make it quick

is it any good and worth 30Euros+ shipping wich makes about 45-50 euros

It seems to be really great,but I don’t know why one should buy a unity book if we can have plenty of great quality material on the web

I wouldn’t buy it. I don’t think (only my opinion, of course) that it’s a good way to mix two things in one book. If you want to learn Unity, start form the official tutorials. If you want to learn C#, start from it’s specification, for example, or buy a good C# book (Throelsen wrote a book for new C# users, it’s rather clear).

I get Headache if i read something off from computer screen

I have it and found it to be a fantastic resource. While there are NUMEROUS tutorials freely available, you often get what you pay for with them. This text is also less a tutorial and more a walkthrough on integrating Interfaces, methodologies, and design patterns into your Unity code.

Scripting is going to be a problem then. Perhaps you need glasses. I don’t wear mine all the time, but some days my vision is a little off and if I don’t wear them while looking at the screen I get a headache.

I don’t buy CS books on game engines. They tend to be of poor quality due to mixed focus.

Well i just get headache when im reading something off monitor other than that i don’t have a problem(i have glasses anyway)
